Flow-dividing transferring opening for utility tunnel drainage cabin

Abstract

The invention discloses a flow-dividing transferring opening for a utility tunnel drainage cabin. The flow-dividing transferring opening comprises a rainwater and sewage passing tank culvert which isarranged on the lower portion of the standard section of a utility tunnel; the rainwater and sewage passing tank culvert comprises a rainwater passing tank culvert body communicating with a rainwatertank culvert cabin, and a sewage passing tank culvert body communicating with a sewage tank culvert cabin; drainage through-wall casing pipes are pre-embedded on wall plates at the ends of the rainwater passing tank culvert body and the sewage passing tank culvert body, and thus the rainwater passing tank culvert body and the sewage passing tank culvert body can be connected to a municipal drainage system in the direction perpendicular to the way side of the utility tunnel through a pipeline. According to the flow-dividing transferring opening for the utility tunnel drainage cabin, the problems that a traditional drainage piping enters the utility tunnel, the drainage lower points are located on the side close to an integrated cabin, rainwater and sewage cannot cross the tunnel integratedcabin to be drained in the process, consequently, the drainage pressure at the tail end is excessively large are solved; and by combining the arrangement of a corresponding rainwater inspection well and a sewage inspection well, the drainage requirements of land blocks on the two sides of a road are met, and meanwhile, overhauling is convenient.

Description

technical field [0001] The invention relates to the problem of drainage in the middle of a drainage pipeline entering a comprehensive pipe gallery, in particular to a diversion transfer interface of a drainage compartment of a comprehensive pipe gallery. Background technique [0002] In order to make intensive use of urban construction land and adapt measures to local conditions to benefit the longitudinal slope of roads, gravity flow pipelines such as rainwater and sewage and other municipal pipelines are included in the centralized management and arrangement of comprehensive utility corridors. For drainage pipelines entering corridors, some main lines and branch lines have long comprehensive pipe corridors, and all the rainwater and sewage collected in the plots along the lines are poured into the rainwater tanks of the pipe corridors, which will cause excessive drainage pressure at the end of the pipe corridors; because the comprehensive pipe corridors have certain Coveri...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a diversion transfer interface for the drainage compartment of the comprehensive pipe gallery, which can overcome the problem of excessive drainage pressure at the end of the pipe gallery caused by the terrain problem and the inability to drain water in the middle due to the drainage pipeline being incorporated into the comprehensive pipe gallery
