Anti-sedimentation structure and method for building drainage outdoor pipe

Abstract

The invention relates to the technical field of building drainage systems, in particular to an anti-sedimentation structure for a building drainage outdoor pipe. The anti-sedimentation structure comprises a building inner wall column, a building outer wall, a building bottom plate, a sewage drainage pipe, a sewage eduction pipe and a sewage and wastewater inspection well, the sewage drainage pipe comprises a first drainage vertical pipe, a second drainage vertical pipe, a drainage horizontal pipe, a first connecting elbow and a second connecting elbow, a third connecting elbow is arranged on the side, close to the sewage drainage pipe, of the sewage eduction pipe, the bottom end of the second drainage vertical pipe is inserted into the vertical end of the third connecting elbow, a rubber ring or asphalt sesame oil is arranged at the joint of the third connecting elbow and the second drainage vertical pipe, and one end, far away from the sewage drainage pipe, of the sewage eduction pipe communicates with the sewage and wastewater inspection well. The invention further discloses an anti-sedimentation method. The anti-settlement structure is easy to install and high in non-uniform settlement resisting capacity, and due to the fact that pipeline wiring is simple and clear, maintenance is easy, and certain extension adaptability is achieved.

Description

technical field [0001] The invention relates to the technical field of building drainage systems, in particular to an anti-settling structure for building drainage outlet pipes. The invention also relates to a subsidence prevention method for building drainage outlet pipes. Background technique [0002] In the drainage system, the drainage pipe is an essential part of the connection between the drainage pipes in the building and the outdoor drainage pipe network. It covers sewage pipes, waste water pipes and storm water pipes. Construction sewage or waste water is fed into the sewage or waste water standpipe by the sanitary appliances through the sewage or waste water branch pipe, and the standpipe is discharged to the outdoor sewage and waste water inspection well along the inner and outer wall columns of the building in the water pipe well. Rainwater or snowwater is guided by the slope of the roof to the rainwater gutter, enters the rainwater bucket and enters the rainwa...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an anti-settlement structure and method for building drainage outlet pipes, which solves the problem that in areas with poor geological conditions and serious ground subsidence, the foundation of the pipeline will be damaged due to uneven settlement in the outdoor field, and the drainage pipe will be broken. , leading to problems such as poor drainage in the building and sewage overflow in the toilet, it can effectively offset the uneven settlement of the outdoor pipeline within a certain limit and cause the breakage of the outlet pipe, and achieve the function of "effective, easy to install, and easy to maintain"
