Claims

[Scope of utility model registration request]

It consists of an inflow side socket, an outflow side socket, and an inspection port side socket, and the pipe axis connecting the inflow side socket and the outflow side socket is bent at a large angle of 90°. The outer circumferential axis of the inspection port side socket is perpendicular to the pipe axis, and the inner circumferential axis of the inspection port side socket is inclined at an angle θ toward the inflow port with respect to the perpendicular to the pipe axis. The upper end surface of the inspection port side socket is perpendicular to the inner circumferential axis, and the inner periphery of the inspection port side socket has a tapered shape whose diameter gradually decreases downward, and the taper angle α is a mold for forming a drainage basin whose angle is equal to or larger than the angle θ, and includes an outer mold having a mold surface shape corresponding to the outer surface shape of the drainage basin, and the pair of inflow side sockets. , an inner mold for molding a socket part having a mold surface shape corresponding to the inner surface shape of the outflow side socket part and the inspection port side socket part, respectively, and the inner mold for molding the inspection port side socket part has a mold surface shape corresponding to the inner surface shape of the outlet side socket part. A mold for a drainage basin, characterized in that it is rotatable around a perpendicular to a pipe axis connecting a side socket and an outflow side socket.
