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

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
