Title: Invert of manhole and manufacture thereof
Inventor: SATO HIROSHI
IPC: E03F5/02
Filed: 1992-08-22
Abstract: PURPOSE:To facilitate the manufacturing by forming a conical recess in the center of the upper face an invert and providing a straight groove having a width smaller than the diameter of the recess from the recess toward a sewerage pipe. CONSTITUTION:Water flowing from a sewer pipe 3 reaches a recess 5 via straight groove 6 and then flows through another groove 6 into another sewer pipe 3. Next, when the water enters the recess 5 from the groove 6, the flow of water becomes slower, and hence mud tends to accumulate in the recess 5 so that earth and sand are separated. And in the case of washing of the pipe 3, a washing machine can easily be inserted into the pipe 3. Further, the groove 6 has a straight shape and hence the pipe can be manufactured more easily as compared with a conventional curved one. As a result, the manufacturing can be performed in a simple manner and the cost is reduced and a washing machine can easily be used and further can turn slowly around the recess, so that the water is allowed to flow smoothly.
