するものである。According to the waterproof manhole of the above construction, (1) the contact portion between the manhole cover and the PVC pipe is provided with watertightness by press-fitting two types of packing. (2) PVC pipes mainly composed of manholes are usually constructed vertically, and the manhole cover mounted on the pipes is often constructed inclining according to the water gradient of the road. The gap is not the same, and one point is pressurized and the other creates a gap. In this case, the tube-shaped packing fitted into the groove has a performance of absorbing the displacement of the pressing height, that is, the one that absorbs the height corresponding to the radius of the packing assuming that the cross section is used from a full circle to a half circle. It is. (3) Further, if a hollow portion is provided at the upper part of the inverted U-shaped packing fitted into the upper edge of the PVC pipe, it has the same effect as the above-mentioned tubular shape and has the effect of increasing the displacement absorption amount. is there. (4) The packing is protected from external force by hanging the skirt on the outer periphery of the groove formed in the receiving frame, and the posture is fixed by screwing the packing to the PVC pipe.
