Description:
System for efficient collection and drainage of groundwater

The subject of the invention is a system for efficient collection and drainage of groundwater which collects groundwater continuously and thus protects the building from the groundwater with the help of water drain units that can be placed next to foundations of buildings easily and even subsequently.

Protection of building from groundwater is a reoccurring problem for the construction industry. At certain places the problem cannot be resolved entirely by just providing various waterproofing to the parts of the building in the ground, its foundation and cellar walls. Where the terrain is sloping, the flow of groundwater could be consistent and in the given case rather strong, and the waterproofing cannot ensure sufficient solution. One of the most frequently used solution utilizes so called drain pipes laid in the ground next to the foundation of houses at various levels, by which drain pipes the groundwater can be collected and drained. This solution, however, requires large space and extensive work, because the drain pipes are usually placed in gravel bedding, which needs strenuous manual work.

According to the state of art the patent US 9 045 874 makes known a drain assembly for being placed at outdoor environment, which includes a first panel and a second panel spaced-apart from the first panel, a plurality of supports extending between the first panel and the second panel. And furthermore, a water collecting element is located at the bottom of the two panels, and their top is provided with a lid.

The patent publication US 2007/0294966 makes known a water drainage system to be used in waterproofing system of cellars. The pipeline has one or two lateral elements with openings to receive water beneath ground level. The pipeline may include an intermediate element also, which provides further strengthening of the structure. 0

The PCT patent description publication WO 98/11300 makes known drainage channel, which can be used when establishing a network to guide the drained water to the rainwater collector.

The British patent GB 2 087 457 makes know inner liner pipe for sewers.

The above solutions ensure collection and draining of groundwater with various methods. Experiences indicate that the quantity of groundwater flowing into the water collecting unit is low through the holes prepared on the side walls of the water collecting units placed in the ground with vertical walls. In this case the groundwater flows down on the side wall of the water collecting unit, and as the water cannot get into the collecting unit, it is only guided to a greater depth, and it is not collected or drained. Accordingly, the solutions described above cannot ensure a proper collection and drainage of water being in the ground.

While developing the solution according to the invention we had the aim of creating a water drainage system, by which it is possible to collect and drain the groundwater accumulating at the underground parts of the buildings in a more efficient manner, so that the water flowing down the side wall of the water collecting unit placed in the ground could be introduced inside the water collecting unit, and furthermore, we had the aim to provide a solution, by which the given groundwater drainage system could be deployed in a simple manner, and that it could be cleaned on a regular basis.

During the realization of the solution according to the invention we recognised that, if an arched surface with a given radius R, preferable shaped as a half circle is formed at the cross section of lower longitudinal water collecting element of the water collecting unit, and one of the upper edges of the water collecting element has a strait connecting part having a given length H, while the other edge of the water collecting unit is provided with an inwardly offset flange having water inlet holes, and this protruding flange has another straight upper connecting part having a given length H, and the width width S of the lower connecting element of the unit, then the set out aim can be achieved.

It is characterised by that, the longitudinally aligned lower collecting element of the water drainage unit is formed with an arched surface having preferably a semicircular shape with R radius, and one upper edge of the water collecting element has a straight connecting part having a given H length, while the other edge of the water collecting element has an inwardly offset flange in which water inlet holes are created, and has another straight upper connecting part having a given H height extending upwards on this inwardly offset flange, and the 2R width of the internal part of the arched water collecting element is larger than the external S width of the connecting part of the water drainage unit.

In a preferred embodiment of the solution according to the invention a flange, having water inlet holes, is mounted at both edges of the arched surface of the water collecting element.

In another preferred embodiment of the system according to the invention the holes in the inwardly setoff flange are circular or rectangular, and preferably are formed at one end of the water collecting element with arched fixing flange and an internal arched flange.

In a further preferred embodiment of the solution according to the invention a closed lid, or a perforated lid of a sloping lid having flange and groove is connected in a shape closing manner to the internal side wall and the external side wall at the top of the water drainage unit.

In a further preferred embodiment of the solution according to the invention one or more corner units, which are formed in the given case with planar surface or angular surface, are connected to the water drainage unit.

In a further preferred embodiment of the solution according to the invention an opening is formed at the lower part of the closing plate formed with coupler pins and flat surface or angular surface of the corner unit, and external positioner surfaces are fixed to the external surfaces of the coupler pins, while internal positioner surfaces are fixed to its internal surfaces, and the external positioner surfaces and the internal positioner surfaces form the arched grooves, and there is a profile shaped part at the lower part of one shank of the internal positioner surfaces in front of the arched section, and there is a profile shaped part at the lower part of the same shank of the external positioner surface in front of the arched surface, and the profile shaped parts form a nest in a way, that the shape of the nest is congruent with the U shaped flanges created at the bottom of the internal side wall and the external side wall, and furthermore, a profile shaped part is formed at the lower part of the other shank of the internal positioner surface in front of the arched surface, and there is a further profile shaped part at the lower part of the external positioner surface in front of the arched surface, and the profile shaped parts form a nest, which nest is congruent with the other nest, and furthermore, there is a profile shaped part at the lower part of one shank of the internal positioner surface of the corner unit in front of the arched section, and there is a profile shaped part on the lower part of the same shank of the external positioner surface in front of the arched section, and the profile shaped parts form a nest, and there is a profile shaped part at the lower part of the other shank of the internal positioner surface in front of the arched section, and there is a profile shaped part at the lower part of the external positioner surface in front of the arched section, and the profile shaped parts form a nest.

Fig. 11 shows a possible embodiment of the installation of the water drainage unit. Fig. 12 shows a further possible configuration of deploying the water drainage unit. Fig. 13 shows a further possible configuration of the installation of water drainage unit. Fig. 1 shows a possible embodiment of the water drainage unit 1 of the system according to the invention with perspective view. The water drainage unit 1 can be seen in the figure in a condition before assembling. As can be seen in the figure, there is an internal side wall 6 and an external side wall 7 provided with holes 17, having fixing flanges 12 at their ends. The internal side wall 6 and an external side wall 7 are provided with U shaped flange 13 at their bottom, which U shaped flange 13 contains a groove 14. In addition to that, the internal side wall 6 and an external side wall 7 are connected with braces 8. At the same time, the length of the braces 8 determine the distance between the internal side wall 6 and the external side wall 7.

It can be seen well in the figure, that a closed lid 4 is placed on the top part of the internal side wall 6 and the external side wall 7. The closed lid 4 has a flange 10 and the groove 11 next to the flange 10. In this way, the top parts of the internal side wall 6 and the external side wall 7 are fixed into the grooves 11 of closed lid 4 in a shape closing manner.

The figure also shows, that an arched water collecting element 9, shaped as a half circle, is connected to the lower parts of the internal side wall 6 and the external side wall 7, so that its two edges are fixed into the grooves 14 of the internal side wall 6 and the external side wall 7.

The water collecting element 9 is created with a horizontal inwardly offset flange 60, and water inlet holes 67 are prepared in the flange 60. There is an arched fixing flange 15 formed on the external surface at one end of the water collecting element 9, and there is an internal arched flange 16 on its internal surface. The function of fixing flanges 12, the arched fixing flanges 15 and the internal arched flange 16 is to make sure that the ends of internal side wall 6 and the external side wall 7 are accurately aligned side by side when the water collecting units 1 are fitted together in longitudinal direction one by one. In addition to that, the fixing elements 12 that protrude at the internal side wall 6 and the external side wall 7 align the water drain units 1 relative to one another, and they also ensure a cover at the fitting parts. At the same time, the lower water collecting elements 9 of the water drainage units 1 are fitted together in a way, that the end of one water collecting unit 9 is slid between the arched fixing flange 15 of the other water collecting unit 9 and the internal arched flange 16. Here the necessary cover is ensured by the arched fixing flange 15.

Fig. 2 shows a possible embodiment of the water drainage unit 1 in fitted condition. It can be seen in the figure, that in this case two water drainage units 1 having internal side walls 6 and the external side walls 7 are assembled in a way, that the upper edges of the lower water drainage unit 1 are fitted into the groove 14 of the upper water drainage unit 1 in a shape closing manner. The sloping lid 58 is placed on the top of the water drainage unit 1. A water collecting element 9 provided with flange 60 is fixed to the bottom of the lower water drainage unit 1 in a way, that the upper edges of the water collecting element 9 are fitted into the groove 14 of the lower water drainage unit in a shape closing manner.

The largest width S of the water drainage unit 1 is shown in the figure at the external plane of the U shaped flange 13. The internal width 2R of the arched surface 61 of the water colleting element 9 is also shown. Because of the width of flange 60, the internal width 2R of the arched surface 61 of water collecting element 9 shall be larger than the maximum width S of the water drainage unit 1. This arrangement ensures that the water flowing down the external side wall 7 will get into the water collecting element 9 for sure. In the given case, it is possible to place a flange 60 at both edges of the water collecting element 9, as a result of which the water flowing down can be collected at both sides of the water drainage unit 1 , and it can be routed inside the water collecting element 9.

Fig. 3 shows the water collecting element 9 of the water drainage unit 1 according to the invention in perspective view. Fig. 4 shows the top view of the water collecting element 9 introduced in Fig. 3. Fig. 5 shows section B-B indicated in Fig. 4. There is an inwardly offset flange 60 having a length L formed at one side of the arched surface 61, which has a semicircular shape with radius R, of the water collecting element 9, and water inlet holes 67 are created in it, and there is an opening 17 in it. Additional items that can be seen in the figure include one of the connecting parts 62 having height H formed at the edges of the water colleting units, together with the other connecting part 72 having height H, and the arched fixing flange 15 at one end of the water collecting element 9, and the internal arched flange 16. In case of another possible preferred embodiment, the water collecting element 9 may be established in a way, that the flange 60 having water inlet holes 67 is formed at both edges of the arched surface 61 of the water collecting element 9. In this case the radius R of the arched surface 61 is to be increased, so that the connecting parts 62, 67 could fit into the grooves 14 formed by the U shaped flanges 13 of the internal side wall 6 and the external side wall 7 in a shape closing manner.

Fig. 6 shows a possible embodiment of the lower corner unit 2 of the system according to the invention. The figure shows the closing plate 20 of the corner unit 2 created with coupler pins 28, 29, together with an opening 21 formed at its lower part. In this case the closing plate 20 is formed with a flat surface 63. It can be seen, that external positioner surfaces 23, 26 are fixed to the external surfaces of the coupler pins 28, 29, while internal positioner surfaces 22, 25 are fixed to their internal surfaces.

It can also be seen, that the external positioner surfaces 23, 26 and the internal positioner surfaces 22, 25 fixed to the coupler pins 28, 29 actually form the arched grooves 24, 27.

As can be seen the in the figure, there is a profile shaped part 43 on the lower part of one shank of the internal positioner surface 22 in front of the arched section, and there is a profile shaped part 45 on the lower part of the same shank of the external positioner surface 23 in front of the arched section, and the profile shaped parts43, 45 form the nest 44. The shape of the nest 44 is congruent with the U shaped flanges 13 formed at the bottom of the internal side wall 6 and the external side wall 7. As can be also seen the in the figure, there is a profile shaped part 46 on the lower part of the shank of the internal positioner surface 22 in front of the arched section, and there is a profile shaped part 48 on the lower part of the external positioner surface 23 in front of the arched section, and the profile shaped parts 46, 48 form the nest 47. The shape of the nest 47 is congruent with the U shaped flanges 13 formed at the bottom of the internal side wall 6 and the external side wall 7.

As can be seen also in the figure, there is a profile shaped part 43 on the lower part of one shank of the internal positioner surface 25 of the corner unit 2 in front of the arched section, and there is a profile shaped part 45 on the lower part of the same shank of the internal positioner surface 25 in front of the arched section, and the profile shaped parts 43, 45 form the nest 44. The shape of the nest 44 is congruent with the U shaped flanges 13 formed at the bottom of the internal side wall 6 and the external side wall 7. It can also be see, that there is a profile shaped part 46 at the lower part of the other shank of the internal positioner surface 25 in front of the arched section, and there is a profile shaped part 48 on the lower part of the external element 26 in front of the arched section, and the profile shaped parts 46, 48 form the nest 47. The shape of the nest 47 is congruent with the U shaped flanges 13 formed at the bottom of the internal side wall 6 and the external side wall 7.

The application of the corner unit 2 is necessary when water drainage units 1 located at the corner of the building needs to be combined in a single system while the groundwater drainage system according to the invention is being implemented, and when the water collected here needs to be drained. In this case the water drainage units 1 coming from two directions are coupled to the corner unit 2 in a way that the internal side wall 6 and external side wall 7 of the water drainage unit 1 are slid into the upper section of the arched groove 24 in a shape closing manner. At the same time, its water collecting element 9 is slid into the lower arched part of the arched groove 24, and in this case the U shaped flanges 13 of the internal side wall 6 and external side wall 7 are slid into the nests 44, 47 also in a shape closing manner. The same process is repeated at the other side of the corner unit 2 where its groove 27 is located. The corner unit 2 shown in Fig.6 in the given case is suitable for establishing a corner with inclination angle a = 90°, but it can be produced also with any inclination angle in the range 45° < a < 135°. Fig. 7 shows the extension unit 3 of the comer unit 2 introduced in Fig. 6 in perspective view. If the collection and drainage of groundwater needs to be done in a greater depth, for the purpose of which two or more water drainage units 1 are assembled on top of one another, then the corner unit 2 is to be made higher also. Fig. 7 shows a possible embodiment of the extension unit 3.

The figure depicts the closing plate 30, created with coupler pins 51, 52, of the extension unit 3, which in this case is formed with a flat surface 65. The external positioner surface 33, which has a fixing flange 39 at its lower part, is connected to the external part of the coupler pin 51, while the internal positioner surface 32, which has a fixing flange 40 at its lower part, is connected to its internal part. It can be seen, that a groove 34 is created between the internal positioner surface 32 and the external positioner surface 33.

Furthermore, the external positioner surface 36, which has a fixing flange 39 at its lower part, is connected to the external part of the coupler pin 52, while the internal positioner surface 35, which has a fixing flange 40 at its lower part, is connected to its internal part. It can be seen, that a groove 37 is created between the internal positioner surface 35 and the external positioner surface 36.

It can also be seen, that an internal positioner 54, which is provided with fixing element 41 at each lower part, is connected to the closing plate 30 through braces 38, to which a coupler pin 53 is connected, and an external positioner 55, which is provided with fixing flange 42 at each lower part, is connected to the external part of the coupler pin 53. Grooves 56 are created between the internal positioner 54 and the external positioner 55.

Fig. 8 shows section B-B of corner unit 2 introduced in Fig. 6.

Fig. 9 shows a further possible embodiment of the corner unit 2 of the system according to the invention. The corner unit 2 created according to Fig. 6 can be seen here, but in this case the closing plate 20 is made with an angular surface 64.

Fig. 10 shows the extension unit 3 of the corner unit 2 introduced in Fig. 9 in perspective view. The extension unit 3 created according to Fig. 7 can be seen here, but in this case the closing plate 30 is made with an angular surface 66.

Fig. 1 1 shows a possible embodiment of the installation of the water drainage unit 1. The wall of building 49 and the foundation 57 of the building, as well as the closely located water drain unit 1 can be seen in the figure. In this case the water drain unit 1 is located entirely below the soil 50, therefore a closed lid 4 is placed on the water drain unit 1. If a perforated lid 5 is placed here to enhance drainage, then so called geotextile is to be laid on the cover to catch the earth.

AITOWS are placed in the figure to show where the groundwater seeps into the water drainage unit 1 through the holes 17. It can be seen well, that part of the groundwater coming from the soil 50 flows down on the external wall 7 and enters into the water collecting element 9 through the holes 17 created in the flange 60 of the water collecting element 9. Fig. 12 shows a further possible configuration of deploying the water drainage unit 1. The building wall 49 and the building foundation 57, together with the water drainage unit 1 placed directly next to it can be seen in the figure. In this case the water drainage unit 1 is installed in a way, that its top parts extend slightly over the soil 50, therefore an outward sloping lid 58 is placed on the water drainage unit 1.

Arrows are used in the figure to show where the groundwater flows into the drain 1 through the holes 17. It can be seen well, that part of the groundwater coming from the soil 50 flows down on the external wall 7 and enters into the water collecting element 9 through the holes 17 created in the flange 60 of the water collecting element 9.

Fig. 13 shows a further possible configuration of the installation of water drainage unit 1. The building wall 49 and the building foundation 57, together with the two water drainage units 1 fitted on top of another directly next to it can be seen in the figure. In this case the lower water drainage unit 1 is entirely below the soil 50, while the upper unit is located in a way, that its top part slightly extends over the soil 50, therefore a perforated lid 5 is placed on the water drainage unit 1. Arrows are placed in the figure to show where water seeps into the water drainage unit 1 through the holes 17.

In case of an actual embodiment and application the elements of the system according to the invention are made of plastic or glass fibre reinforces resin and is installed in trenches dug in the soil 50 next the building foundation 57, and the system protects the house or building foundation 57 in this way from the groundwater seeping in lateral direction. Large portion of the side towards the house or building is closed, and at the bottom in the given case is provided with a row of holes 17, while its external side being in contact with the soil is perforated on a large surface having holes 17, so that it could collect groundwater from lateral direction into itself.

The entire system shall be sloped in a single direction, so that the collected water could be drained. It is routed into tank placed in the soil 50, into ditch or water collecting well. The elements of the system are established in a way, that they can be extended in every direction. At the fitting parts the corners shall be formed with bevels, so that they could be slid easily into one another. The elements of the system in the given case are preferably provided with lid, the top of which lid may be perforated or closed, which closes and protects the system from blocking. The lid may be flat closed lid 4 and/or perforated lid 5 and or sloping lid 58. The internal part of the lid is formed in a way that it functions also as a spacer.

The water drainage unit 1 is configured in a way, that it can be cut at the given angle, so that the drop of the terrain could be followed, and the lid can be placed on it in this case too. The water drainage unit 1 shall be installed with suitable gradient, so the water could not remain in it. The diameter of the holes 17, 67 created in its side and in the flange is about 2-3 mm.

The water collecting element 9 has a length L, the cross section of which is formed with arched surface 61 having semicircular shape with radius R, at one of its sides an inwardly offset flange 60 is formed, and water inlet holes 67 are created along a length L in the flange 60. Both sides of the arched surface 61 of the water collecting element 9 are terminated with a connecting part 62, and an arched fixing flange 15 and an internal arched flange 16 is formed at one end of the water collecting element 9.

The advantages of the system according to the invention:

- The collected water is not let back into the ground. It means that a larger amount of water can be collected for utilization.

- With the help of the holes formed along the brim of the water collecting element it is possible to collect water more efficiently.

- It can be produced in any size, and the ready elements can also be formed.

- It can be assembled easily and quickly.

- The spoil is less after competing the work.
