COLLECTING PIPE FOR DRAINAGE

摘要

PROBLEM TO BE SOLVED: To provide a collecting pipe for drainage capable of facilitating piping design and construction, and preventing breakage of a trap of facilities for drainage by aligning the shaft core of a joint part of a lateral drainage pipe connecting part with a shaft core of a drainage collecting pipe. SOLUTION: This collecting pipe for drainage is formed by a collecting pipe body having a large bore diameter than a vertical drain pipe and a lateral drain pipe for connecting the lateral drain pipe to the collecting pipe body, and the lateral drain pipe connecting part is formed by bending and connecting an inflow part for making drain of each floor flow in the tangential direction of the collecting pipe body and a connecting part having a shaft core passing the shaft core of the collecting pipe body. A drain guide plate pointing in the axial direction is provided on the upper part of the inner surface positioned on the collecting pipe body side of the inflow part.
