Pipe-culvert combined sewage interception structure with functions of sewage discharge and initial rainwater regulation and storage

Abstract

The invention provides a pipe-culvert combined sewage interception structure with functions of sewage discharge and initial rainwater regulation and storage. The sewage interception structure includesa box-culvert structure which is embedded in a municipal drainage pipe network; and a front-end regulation and storage tank, a main regulation and storage tank and a drainage tank are arranged in sequence from upstream to downstream in the box-culvert structure, and the drainage tank is connected with a municipal drainage pipe on the downstream side of the box-culvert structure; and a normal drainage channel is arranged on the upper part inside the box culvert structure and directly communicates with the municipal drainage pipe on the downstream side of the box culvert structure without passing through the drainage tank. According to the pipe-culvert combined sewage interception structure with the functions of the sewage discharge and initial rainwater regulation and storage, collecting and transferring of sewage can be completed in a dry season under the condition of limited land use conditions, and the phenomenon that mixed sewage overflow is directly discharged into a river causedby a combined drainage system during a rainy season can further be effectively coped with; and sewage conveyance and initial rainfall regulation and storage are integrated to enable combined sewage overflow pollution to be easier to be controlled. The sewage interception structure can be applied flexibly at the front end, the middle end and the tail end of a sewage collection system based on various engineering characteristics.

Description

technical field [0001] The invention relates to a pipe-culvert combined sewage intercepting structure with the functions of sewage discharge and primary rain regulation and storage. It is suitable for sewage discharge, regulation and storage and similar projects in water conservancy, municipal and other engineering fields. Background technique [0002] The problem of urban water environment pollution is becoming more and more serious, especially the phenomenon that the combined rain and sewage sewage is directly discharged into the river, and the combined sewage is often intercepted and collected in the form of sewage interception along the river. During the rainy season, due to the influence of the effective volume of the sewage interceptor, the part exceeding the capacity will overflow, and the mixed-flow sewage will be directly discharged into the river. In view of the above phenomenon, in order to effectively control the overflow pollution of the combined system, measur...

AI Technical Summary

Problems solved by technology

In view of the above phenomenon, in order to effectively control the overflow pollution of the combined system, the measures of setting up mixed-flow sewage storage tanks are generally adopted, but the storage tanks occupy a large area, and the urban land conditions are often limited, and the measures for mixed-flow sewage storage tanks are difficult. be effectively implemented
