Underground rainwater and sewage mixed-discharging and shunting pipe network

Abstract

The invention provides an underground rainwater and sewage mixed-discharging and shunting pipe network. A discharge pipe into which rainwater and sewage are discharged in a mixed manner, a sewage drainage pipe and a rainwater drainage pipe are separately arranged on the periphery in an inspection sinking well, wherein the lower parts of the discharge pipe, in which the rainwater and the sewage are discharged in the mixed manner and the sewage drainage pipe, are positioned at the bottom of the inspection sinking well at the same height; the rainwater drainage pipe is higher than the discharge pipe and the sewage drainage pipe. When the underground rainwater and sewage mixed-discharging and shunting pipe network is mounted and used, the rainwater and the sewage in a residential area can be discharged outwards and directly enter the discharge pipe to share one pipeline; after the rainwater and the sewage enter the inspection sinking well, the commonly produced domestic sewage is directly discharged into an urban sewage pipe network from the sewage drainage pipe because the rainwater drainage pipe is higher than the sewage drainage pipe; when a large amount of rainwater is produced, the rainwater can be discharged outwards through the rainwater drainage pipe which is higher than the bottom if the amount of the water which enters the sinking well is large; therefore, the waste caused by separately setting discharging amounts is favorably reduced.

Description

technical field [0001] The invention relates to an underground drainage pipe for construction of urban districts, in particular to an underground rainwater and sewage mixed discharge and diversion pipe network. Background technique [0002] In urban construction, since the rainwater and sewage are discharged from the external pipe network, the rainwater discharge pipes and sewage discharge pipes must be buried in the underground of each building during the construction of each community, so that the rainwater and sewage are separated from the rainwater pipes in the city. The main reason is that the direction of diversion is different. However, in actual application, the generation of rainwater discharge is limited, while the generation of sewage discharge is continuous, but the discharge of rainwater is relatively large, and life The amount of sewage discharge is limited, so it is a great waste to set up discharge pipes separately, and it also creates a complicated situation...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned complex and wasteful problems of separately setting up pipe networks for discharge, and to provide an underground rainwater and sewage mixed discharge and diversion pipe network, which can allow rainwater and sewage in the community to share the same pipe when they are discharged.
