Abstract

The invention relates to a drainage system for old toilet room reconstruction, and aims to solve the problems that an old community toilet drainage pipeline system often has odor, floor holes need tobe knocked and repaired during reconstruction, and the pipeline replacement difficulty is high. According to the technical scheme, the drainage system for old toilet room reconstruction is composed ofa drainage vertical pipe, a sewage transverse branch pipe, a waste water transverse branch pipe and an integrated water seal, wherein the sewage transverse branch pipe is connected with a toilet bowlfor drainage; the waste water transverse branch pipe is connected with the integrated water seal before being connected with the drainage vertical pipe; a drain trap is not arranged for drainage of afloor drain, a washbasin, a shower or a bathtub any more, and all the drainage is connected into the integrated water seal; the top end of a new vertical pipe, the sewage transverse branch pipe and the waste water transverse branch pipe are all bell mouths in the upward direction; and rubber rings are arranged in the bell mouths to form sealing with an old drainage pipe and a floor. The drainagesystem can achieve the effects that floor holes do not need to be knocked and repaired during old toilet room reconstruction, pipelines are quickly updated and reconstructed, connectors are not proneto water leakage, the toilet water seal is not prone to drying up, a room is not prone to odor, and the height space of the room is increased.
