WIPO Patent Application WO/2020/248264
Kind Code:
A1
Abstract:
Provided is a fabricated-type building drainage pipe shaft, comprising a base (1), wherein two sides of a top of the base (1) are separately and fixedly provided with a first side plate (2) and a second side plate (3), one side of the first side plate (2) is fixedly provided with a plurality of prefabricated blocks (7) symmetrically arranged, one side, away from the first side plate (2), of each of the prefabricated blocks (7) is provided with curved-surface grooves (8), and a standpipe (9) is movably clamped into the curved-surface grooves (8). The problems of the pipe shaft being subjected to on-site concrete casting, such that casting is very difficult, and the construction period is long; and the pipe shaft not being internally provided with a prefabricated member for mounting a pipe, which results in mounting of a drainage pipe at a later stage being tedious, consuming manpower and material resources, and the investment costs being high, are solved.
