Description:
Penetration Testing Apparatus The present invention relates to a penetration testing apparatus for testing the bearing strength of ground, soil layers, base-courses, subbases and subgrades without the need for manual operation. The invention is directed particularly but not solely towards a penetration testing apparatus having a mechanical operation without manual operation that can be removably attached to a support apparatus such as a vehicle and be non-manually and mechanically operated.

Background of Invention

Penetration testing apparatus are commonly used for many years by engineering staff to determine the strength of ground for the location of an engineered structure. These apparatus are part of a system devised consisting of standard apparatus that can cope with different ground types to determine the load bearing capacities of any soil types used for supporting engineering structures such as for example buildings and roads.

Current systems were developed to ensure that there was a simple system that could be consistently operated without complication with standard equipment to ensure meaningful and useful results were achieved. However using current systems has meant using cumbersome and heavy equipment that requires several staff members to transport, set up and operate. The heavy equipment includes a steel penetrating rod and slidably movable heavy weight.

Because the current systems are so heavy they can be very difficult to move over rough terrain to remote locations. Furthermore existing systems require strength to operate which can be tiring to use especially when operating over many sites or test locations. The heavy equipment can provide an ongoing hazard to staff during set up and operation which can compromise the efficacy of the results if for example the heavy weight is not properly lifted to a correct height and dropped correctly and consistently. All of these factors add significant costs to projects including staff wages, potential accidents including serious harm and length of time needed to cany out all testing.

In this specification unless the contrary is expressly stated, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge; or known to be relevant to an attempt to solve any problem with which this specification is concerned. Object of the Invention

It is an object of the invention to provide an improved penetration testing apparatus that ameliorates some of the disadvantages and limitations of the known art or at least provides the public with a useful choice. The apparatus provides an alternative choice that negates much of the manual handling involved with current testing apparatus.

Ground stabilizing means 18 includes stabilizing leg assemblies which each assembly comprise a ram apparatus or ram comprising a leg ram member 55 slidably supported within a tubular ram receiving member 56. The tubular ram receiving member 56 is upwardly and vertically supported on top of the base support frame 20 when retracted and leg ram member 55 (being co-linear with the tubular ram receiving member 56) in use is slidably supported (see cage type frame 57 in figures 1, 2 which each includes side spacing rods and an end ring plate member) underneath base support frame 20 to extend downwardly to the ground to provide support or upwardly above the frame 20 when retracted. There is at least one ground stabilizing means 18 located at each of the base support frame 20, the puipose of which is to allow the vehicle to be raised which in turn allows its mass to be utilised to push ground penetrating member 15.

A seating ram member 60 is adjustable and connected underneath to cantilevered support member 50 of the support frame 20, to ensure that the mast frame 21 when set up to conduct a test is perpendicular to the ground subject to test or at an angle as required by the operator.

As shown in figure 5 the actuating apparatus 7 which is adapted to receive electrical power from the power supply apparatus 9, to power all the components of the apparatus. In this example if using hydraulics, the actuating apparatus can be a hydraulic actuating apparatus which is adapted to receive electrical power from a battery 82 to then convert to provide hydraulic power through appropriate connecting means in the form of hydraulic lines 58 to drive all the hydraulic rams (as part of the ground stabilizing means 18, the mast ram apparatus 19 and ground penetrating members 15), of the present invention, which includes an actuating apparatus housing comprising a rectangle box with side walls 61, roof 62, base 63, front wall 64, rear wall 65 and an enclosed space and filling aperture and cap 66 and at least one outlet drain.

The enclosed space of the actuating apparatus housing includes the following components operatively supported and connected together therein which includes an electric motor 70, a reservoir or tank 71 for hydraulic fluid, a hydraulic pump 72, operating lever members 74 and hydraulic lines 58 (eg tubing with hydraulic fluid therein). The motor 70 and pump 72 can be called a "power pack". The actuating apparatus housing is located between the ram receiving member 56 of the ground stabilizing means 18 and one side of a side of the mast frame 21 with the housing base 63 being connected to upper surface 25 of the base support frame 20. As shown in figure 3 the operating (eg hydraulic) lever members 74 are mounted on platform 53 to allow easy access by the operator. While the hydraulic member mounting platform is shown to be rigidly mounted, this hydraulic member mounting platform 53 may pivot on one corner to allow the operator to change their position of operation. The actuating apparatus 7 is engaged to provide power to cause actuating (eg hydraulic or other) flow to move all the hydraulic rams (as part of the ground stabilizing means, the mast ram apparatus and ground penetrating members), and provide measurement control and a monitoring control bank like for example a computer including a computer operating device 78 eg laptop or tablet etc by wire or wirelessly. The hydraulic power pack (motor and pump) self circulates with operating lever members 74 which controls the mode the particular component is required to carry out which includes up and down modes for the carriage assembly 13, ground stabilizing means 18 and mast ram apparatus 19 directions. A data logger 77 is connected to the computer device 78. Additionally the hydraulic actuating apparatus 7 also has hydraulic valves 80 operatively connected to each lever handle and at least one pressure transducer 81 is operatively connected to at least one of the hydraulic valves 80.

As shown in figure 7 the power supply apparatus 9 includes a power housing which encloses and supports a portable power means in this example in the form of a battery 82. The power housing comprises a rectangle box with side walls 84, roof 85, base 86, openable front wall 87, rear wall 88 and an enclosed space. Additional batteries may be stored on the vehicle to which the apparatus is attached. An emergency Stop device or E stop device 93 is also operatively mounted to the battery 82 as a safety precaution to provide safety cut out when as required. The power supply apparatus 9 is located on an opposite side of the mast frame 21 to that of the actuating apparatus 7, to be located between the mast frame 21 and ground stabilizing means 18 with its base 86 located on top of upper surface 25 of the base support frame 20. The power supply apparatus 9 is operatively connected to the actuating apparatus 7 by supplying electric power to the electric motor 70 which in turn provides and converts power to the hydraulic pump 72 via electrical connecting means such as electric lines 75. Additionally power supply apparatus 9 includes the on/off switch charge controller 92 and an E-stop device 93 which are mounted inside the power housing.

The lever members 74 include several levers (in this example there are six levers 111, 112, 113, 114, 115 and 116) which are operatively connected via the hydraulic connecting means (e g lines) 58 from the hydraulic pump 72 to various components of the penetration testing apparatus 1. The operating lever members 74 include two levers 111, 112 to operate the ground stabilizing means 18, one lever 113 to operate the carnage assembly 13 and two levers 1 14, 115 to calibrate controlled distal movement of the carriage assembly 13 and one lever 116 to control the forward and back adjustment of the mast assembly 58 with seating ram member 60. The mast ram apparatus 19 includes at least one mast ram member 94 and at least one tubular ram receiving member 95 which is operatively connected to a non-end portion of the mast frame 21 and to the carriage drive mechanism 17 of the mast frame 21 to cause mast ram member 94 slidably inside ram receiving member 95 to move from a retracted position to a non-retracted position and vice versa to move the carnage assembly 13 up and down the mast frame 21 as required. In this example the mast ram apparatus 19 can be a hydraulically operated mast ram.

Figures 12-15, show the retracted position with the mast ram member 94 not extended, whereby the carriage assembly 13 is located at a specific position or height at the top of the mast frame 21. Figure 9, shows the mast ram member 94 upwardly extended from ram receiving member 95, to cause the carnage assembly 13 via the chain link member 17 to drop and cause the ground penetrating member 15 to hit or penetrate the ground or soil. Carriage assembly 13 is more clearly seen in figures 15-23 includes a front plate member 100 separated and connected from a rear plate member 102 by a spacer member 104, together forming side channels for sliding receipt by one of side walls (i.e. a front) of each of the side members 35 of the mast frame 21. Front plate member 100 is operatively connected to the chain link member 17. Carnage assembly 13 also includes a carriage hydraulic motor 106 operatively connected to the levers 74 via hydraulic lines 58 to rotate the ground penetrating member 15. The front plate member 100 is connected and operatively supports the carriage hydraulic motor 106.

From left to right as seen in figures 6 and 8 there are five levers 74 whereas in figures 1, 2, 7, 9-11, 23, 24, there are six levers 74.

Levers 111 and 112 control separately or together, the ground stabilizing means 18.

Lever 113 is operatively connected to the carnage hydraulic motor 106 to provide rotational movement i.e. drilling of the ground penetrating member 15.

Lever 114 is operatively connected to slidably move the carriage assembly 13 up and down the mast frame 21 in regard to speed control which allows for coarse control of the carriage assembly 13.

Lever 115 is operatively connected to the carriage assembly 13 for controlled distance movement through a flow control valve or similar allows for controlled adjustment at a constant rate of travel normally for example at 1 meter per minute

Lever 116. Is operatively connected to the mast adjustment ram. This allows the mast position to be adjusted to a perpendicular position when pushing the rod 15 or any other attachment into the ground

As shown in figures 23-32 the penetration testing apparatus 1 can be attached to a rear of a vehicle 122. During movement and positioning of the penetration testing apparatus 1 and vehicle 122, the carriage assembly 13 and ground stabilizing means 18 are both positioned to be in a retracted position as shown in figures 23, 25-29 whereby all the wheels of the vehicle touch the ground. However as seen in figures 29-32 when the apparatus and vehicle 122 are positioned to be ready for testing, the ram members 55 of both ground stabilizing means 18 are caused to be downwardly extended to contact the ground which causes the rear wheels of the vehicle 122 to be lifted off the ground. After that the carriage assembly 13 is moved to a pre-determined height, downwardly during the actual testing process as a constant rate penetrometer test.

The penetration testing apparatus of the present invention can be used to cany out at least one of the following or any other selected tests:

1. Constant rate penetration tests

2. In-situ California Bearing Ratio testing

3. Core cutting tests

4. Auger boreholes tests

5. Cone Penetration testing

These tests utilize different ground penetrating members 15 ie different end members or probes which can be interchanged or combined as required.

Operational Steps

Penetration testing apparatus 1 is removably attached to the rear of a vehicle 122 whereby the apparatus 1 is bolted to a chassis in a similar position to a standard tow-bar.

Power for the penetration testing apparatus 1 is activated by the actuating apparatus 7 run from battery 82. Battery 82 can be recharged by a vehicle alternator so a cable can be installed to electrically connect them if required. Actuating apparatus 7 includes operating lever members 74, hydraulic valves 80 and hydraulic lines 58 which are all operatively connected to the components of the assembly 1 to control movement of the ground stabilizing means 18, the carriage drive mechanism, the caniage assembly 13, in two modes, standard mode allowing user controlled rate of travel and detent which allows a controlled rate of movement independent of the operator accordingly.

As shown in figures 1, 2, 6-20 and 24-32 at the caniage assembly 13, which is operatively connected to the carnage hydraulic motor 106, there is shown a first end member fixing housing 130 which allows for interchanging of the ground penetrating member 15 with other ground penetrating members as seen in figures 33-37. As seen in figures 20-22 there is shown a second end member fixing housing or coupling 132 which includes a manually operated CBR apparatus 135 and load cell 137 which are both operatively connected and powered electrically directly from the battery 82.

The data logger 77 which connects the output of the load cell 137 and the computer device 78 are operatively connected to the components of the apparatus to enable the computer device 78 to control and measure the results of the movement of the ground penetrating member 15. The load cell 137 is connected between the first end member fixing housing 130 and second end member fixing housing 132.

As shown in figures 33-37 the end members or probes of a ground penetrating member 15 can be interchanged with selected end members including:

- Cone penetrometer 140

Coring barrel 142

Split spoon sampler 144

Dutch auger 146

Auger 148

CBR apparatus with end member 139- see figures 20-22

Constant Rate Penetrometer Test

1 The mechanism of the penetration testing apparatus 1 first requires calibration to correlate the force being exerted by the ground penetrating member 15 (eg a probe or rod) to a reading on the load cell 137 of the actuating apparatus 7. Once calibrated, the apparatus 1 can be used for all soil types. As soil resistance increases, the reading from the load cell 137 increases.

2 Operate the levers 111 and 112 whereby the leg ram members 55 are extended downwards. At this stage leg ram members 55 can allow for the levelling of the rear of the vehicle 122 as required. 3. If required lever 116 can be used to adjust the position of the mast frame 21 in a forwards and backwards motion. This allows the rod 15 to be perpendicular to the ground surface.

4. Lever 114 is then used to position the carnage assembly 13 so the rod cone tip 85 comes into contact with the ground. The movement of the mast ram member 94 by this lever 114 allows for the rapid movement to quickly find the required position. The arrangement of the carriage drive mechanism increases the movement of the carnage assembly 13 by a magnitude of 2 or greater than the movement of the mast ram member 94.

5. Once in position lever 115 is then engaged. In the hydraulic circuit there is a flow control valve (needle valve or similar) to control the speed of the penetration of the rod. Lever 115 has detent capability to allow the motion to be engaged at a constant rate of penetration, and maintained without operator interaction so that they are free to interact with monitoring and recording the load cell output 137. Measurements should be taken at every 50 to 100mm of penetration or at specific time intervals as required to allow a profile of bearing strength compared with depth to be plotted. Where fitted a linear transducer can be used to measure the distance of the probe has travelled.

6. Once the testing to the required depth of the ground penetrating member 15 in the ground is complete, lever 114 can be used to reverse the direction of the carnage to remove the probe 15 from the ground.

7. Lever 114 is then engaged to rapidly upwardly remove the ground penetrating member 15 from the ground in an upward motion.

8. On completion of the testing, levers 111 and 112 are then engaged to retract the leg ram members 55.

Auger boreholes (see figures 36, 37) and core cutting (see figure34)

1. Operate levers 111 and 112 whereby the leg ram members 55 are extended downwards. At this stage, leg ram members 55 can allow for the levelling of the rear of the vehicle 122 as required. Lever 116 can be used to adjust the position of the mast.

2. Auger length and head to be connected to the carriage assembly 13. 3. Lever 114 is then engaged to move the auger head or coring barrel to be moved into contact with the ground or surface.

4. Once in contact with the ground, lever 113 is engaged to allow rotation of the auger and lever 1 14 is engaged to allow downward motion.

5. To extract the auger or coring barrel, lever 114 is used for upward motion.

Possible examples of attachments for ground penetrating members 15 with different end members:

• Cone Penetrometer 140 as shown in figure 33

· Coring barrel 142 as shown in figure 34

• Split spoon sampler 144 as shown in figure 35

• Dutch auger 146 as shown in figure 36

• Screw Auger 148 as shown in figure 37 In-situ California Bearing Ratio (CBR) Testing using a CBR test rig

1. Operate Levers 111 and 112 whereby the leg ram members 55 are extended downwards. At this stage leg rem members 55 can allow for the levelling of the rear of the vehicle 122 as required. Seating ram member 60 can be used to adjust the position of the mast to allow the CBR plunger 139 to be seated perpendicular to the test location.

2. If required a coring barrel 142 or similar can be attached to the carriage assembly 13 to allow the boring of a hole to test the soil at depth. Once the coring barrel 142 or similar is attached, lever 1 14 is used to move the coring ban-el 142 into contact with the ground. Lever 1 13 will allow rotational movement to cut the hole. Lever 114 can be used for downward movement.

3. If required to cut a hole to test below ground level, once the hole has been cut to the correct depth, lever 113 is engaged to provide an upward motion for the carriage assembly 13.

4. The CBR test rig includes manually operated CBR apparatus 135 and CBR plunger 139, which is then moved into position and the underside of the CBR plunger 139 is moved to make contact with the soil or ground. Manually operated CBR apparatus 135 has a handle which is wound to control the rate of travel of the CBR plunger 139. Accepted rate of movement for the test can be 1mm per minute to a total depth of 7.5mm. The load cell 137 takes pressure measurements which are recorded by the laptop 78 through the data logger 77 for later download and data analysis.

5. On completion of the CBR test, the CBR rig is to be removed by raising the carnage assembly 13. The CBR rig is attached to the load cell 137 and the carriage assembly 13 by fixed housing 130 and coupling 132. The coupling 132 is unscrewed to separate the two (CBR rig and carriage assembly 13). The ground penetrating member 15 including any selected end member (eg 140, 142,144, 146 and 148) can then be re-attached or connected as required.

Throughout the description of this specification, the word "comprise" and variations of that word such as "comprising" and "comprises", are not intended to exclude other additives, components, integers or steps. Hydraulic actuating means is disclosed in this specification as one example of a suitable operating systems able to operate and/or move all or some of the components of the apparatus 1 but equally other activating means such as electrical or pneumatic are also possible either in place of or in combination with.

It will of course be realised that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is hereinbefore described.

The shape, length, height, width, cross sectional shape, number of cross members of the base support frame 20, mast frame 21 and ground supporting means 18 can be varied to suit requirements. Similarly for the support frame 45 this can also be varied without departing from the scope of the invention which can be made larger than that shown or be formed from a different elongate member cross section.

The apparatus can be mounted or removably mounted on a vehicle as shown or a tracked unit, tractor, trailer or any other means of making the unit mobile for field use. The ground penetrating means 15 can include any means of drilling or boring for the puiposes of extracting sample for observation or creating a hole or determining bearing strength. The apparatus shows that a hydraulic power pack (combination of electric motor 70 and pump 72) and/or battery power unit 82 are located on the base support frame 20, and also in another option these maybe mounted on a transport vehicle or replaced by a power take off unit if required.

The flexible drive member 17 can include any means that is both flexible and able to be driven such as for example a chain link member, notched belt member, cable or strap. The number of levers 74 can be varied to suit requirements like for example there are 5 levers shown in figures 6 and 8 whereas the other figures show 7 levers.

It will also be understood that where a product, method or process as herein described or claimed and that is sold incomplete, as individual components, or as a "kit of Parts", that such exploitation will fall within the ambit of the invention. These and other features and characteristics of the present invention, as well as the method of operation and functions of the related elements of structures and the combination of parts and economics of manufacture, will become more apparent upon consideration of the following description with reference to the accompanying drawings, all of which form part of this specification, wherein like reference numerals designate corresponding parts in the various figures.

It is acknowledged that the term 'comprise' may, under varying jurisdictions, be attributed with either an exclusive or an inclusive meaning. For the purpose of this specification, and unless otherwise noted, the term 'comprise' shall have an inclusive meaning - i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components or elements. This rationale will also be used when the term 'comprised' or 'comprising' is used in relation to one or more steps in a method or process.

For purposes of the description hereinafter, the terms "upper", "lower", "right", "left", "vertical", "horizontal", "top", "bottom", "lateral", "longitudinal", "side", "front", "rear" and derivatives thereof shall relate to the invention as it is oriented in the drawing figures. However it is to be understood that the invention may assume various alternative variations, except where expressly specified to the contrary. It is also to be understood that the specific devices illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the invention. Hence specific dimensions and other physical characteristics related to the embodiments disclosed herein are not to be considered as limiting. In this example "front" is meant to refer to a user facing a rear of a vehicle which serves to define a "rear" but this is only a relative orientation with other definitions being equally possible.
