Auxiliary drainage structure and building drainage system

Abstract

The invention relates to the technical field of drainage, in particular to an auxiliary drainage structure and a building drainage system. The auxiliary drainage structure comprises a shell, an innertube and a reaming and cutting device. A first butt joint structure and a second butt joint structure are correspondingly arranged at the upper end and the lower end of the shell. The inner tube is disposed in the shell. The reaming and cutting device is disposed on the inner wall of the inner tube, and the reaming and cutting device comprises reaming and cutting tracks and reaming and cutting blades. The reaming and cutting tracks are fixedly disposed on the inner wall of the inner tube, and each of the reaming and cutting tracks is provided with at least one reaming and cutting blade and thereaming and cutting blades are movable on the reaming and cutting tracks. An excitation structure is further disposed between the inner tube and the shell, and the excitation structure includes a plurality of sets of excitation teeth. The auxiliary drainage structure can ream and cut and break solid wastes in a drain pipe through the reaming and cutting device, and occurrence of problems such asblockage of the drain pipe can be avoided; and the building drainage system is convenient to use, intelligent and efficient, can effectively monitor the entire drain pipe, and can prevent blockage andraise an alarm in time.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to an auxiliary drainage structure and a building drainage system. Background technique [0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage. Drainage pipes are divided into plastic drainage pipes, concrete pipes (CP) and reinforced concrete pipes (RCP). The drainage pipes used in buildings generally undertake the function of sewage discharge at the same time, and the sewage discharge pipes are generally directly connected to the sewage discharge equipment, such as toilets, and the sewage discharge pipes generally also need to undertake the function of sewage discharge, and if the sewage accumulates on the pipe wall, It will lead to changes in the structure of the pipe wall, and even agglomeration. More importantly, if the main sewage pipe is blocked, it is very difficult to unblock it, and at the same time, the ent...
