Urban emergency drainage system with rapid transit and underground pipe gallery functions

Abstract

The invention discloses an urban emergency drainage system with rapid transit and underground pipe gallery functions. The urban emergency drainage system comprises at least one set of complex positioned in an underground space, wherein the complex comprises a rectangular section concrete outer shell, and the outer shell is divided into a top layer and a bottom layer through a split panel; the top layer is a comprehensive pipe gallery layer; the bottom layer is a traffic layer which is used for relieving urban traffic jam in non-flood seasons and for urban emergency drainage in flood seasons, the middle of the traffic layer is bottom-layer small passenger car traffic lanes, traffic emergency evacuation lanes are arranged on the two sides of the traffic layer, a water alarm is arranged on the upper portion of the traffic layer, and at least one drainage pump station is arranged in the traffic layer; and the two ends of the outer shell are provided with water inlets or outlets which communicate with an urban road network and are capable of blocking water and discharging water. According to the urban emergency drainage system, the functions of underground rapid transit, comprehensive pipe gallery and emergency drainage are integrated, so that the urban traffic pressure is relieved, and meanwhile, the storage capacity of city to rainwater and accumulation capacity of city to waterlogging flood are improved.

Description

technical field [0001] The invention relates to underground corridors, in particular to an urban emergency drainage system with the functions of rapid traffic and underground pipe corridors. Background technique [0002] On the one hand, under the background of my country's urbanization and urban modernization, the rapid development of motor vehicles has made traffic problems a common urban problem in modern metropolises and has a lot of social reflection. Widening the existing roads, increasing the density of the road network, and building overpasses and viaducts are common solutions now, and they have also been considered effective for a long time. However, after more than 20 years of construction practice, especially in the core area of ​​the city, due to a series of unavoidable problems such as urban noise pollution, shortage of land resources, damage to the landscape, difficulties in traffic connection, and obstacles to pedestrians, road traffic construction has entered...

AI Technical Summary

Problems solved by technology

[0005] At present, the existing patents in this area mainly consider the solution of urban traffic congestion and urban waterlogging under the concept of "sponge city", and do not consider the method of integrating urban underground pipe corridors, underground rapid transit and urban waterlogging
