| CLAIM As nobody need enter the man hole and thus in hale poisonous gases emanating from the sewer line as sewer block is done from the ground level. It is 100% fool proof. Poisonous gas deaths are avoid. Less labours involved in clearing the block. In this method suggested more thrust can be given easily from the ground or road level with less labour. Sewer blocks may be cleared by Bamboo strips and sewerage cleaning rod as more thrust can be given easily from the ground level. Where sewer block occurs in small lanes jet roding machine can not enter whereas in the method now suggested is implemented there is no necessity for the jet roding machine. |
SEWERAGE BLOCK COMPLETE SPECIFICATION
This Invention relates to human safety and to avoid human suffering in clearing sewerage block in the sewerage system.
The Existing system of sewerage channeling there are Block clearing pits in rectangular at regular intervals which are called man holes, the depth of which is upto 2.50 meter deep in which there is provision for deposit of silt and rubbish a pit below the sewer line to the depth of about half meter which is cleared currently by a new method, whereas when the sewer line is blocked which is parallel to the road there is no proper technology to clear the same as it is difficult it necessitates a man enter the said manhole and clear the block as it is parallel to the man hole.
To overcome the above difficulty and to avoid human entrance in to the manhole which is full of sewerage water and silt I suggest a new civil construction method by which nobody need entering the manhole which is prohibited by recent judicial order.
In the method suggested a civil construction of providing two pipes just below nine inches of the manhole on both side of the Sewer line at right angle as illustrated in the drawing No. l it can be direct pipe line from the mouth of the manhole connecting the main sewer line at point away from the manhole the said pipe may be a parabolic shape to facilitate such operation of Bamboo strip (which is conventionally used currently) sewerage cleaning can be given easily to clear obstinate block.
In the existing system there is no possibility for clearing a obstinate block unless an man enters the manhole which involves danger of inhalation of poisonous gas resulting in death which occurs frequently.
This system suggested is applicable to other man holes as illustrated in my drawing No.2 this manhole deeper than the manhole No. l (this is more than 2.50 meters deep).
Two pipes suggested to be installed on both sides of the man hole should be at 45o more or less deepening upon the depth of the pipe line both side of the manhole just below 9" from the ground level connecting the main sewer line. So that whenever sewer block occurs it can be cleared through the additional pipes originally suggested.
In the old system there is no provision for cleaning the block, as easily as in the method suggested in the invention as per drawing No.3 & 4.
