WATER CONVEYING HOLE AND SOCKET FOR MANHOLE

摘要

PURPOSE: A water conveying hole and a socket for a manhole are provided to be simply installed by offering an assembling-typed manhole supply with separately producing the water conveying hole, the socket and a guide socket by recycling a waste vinyl, to reduce an air and a cost and to improve the working efficiency by finishing a construction in an early stage. CONSTITUTION: A passage is equipped to conform a downstream hole(23) of a water conveying hole(20) formed by a waste vinyl on a lower plate(10) to a right downstream hole(42) of a sphere(40). A drain pipe is connected by reclaiming a socket in the downstream hole(42) of a right wall of the sphere and a guide socket is reclaimed inside an upstream hole(41) left the sphere. And the water conveying hole(20), the guide socket and the socket are equipped to drain a sewage flowed from an inflow pipe in the side by flowing to the water conveying hole(20) inside a manhole when a fall is generated. The water conveying hole is corresponding to various flowing angles because a width of the hole faced from the upstream to the center is widened and the hole is a swelled form and the construction is able as it is when a position is controlled inside a permitted range of the angle in the case that the position of the manhole is changed by obstacles.
