Embankment integrating functions of river closure, regulation and storage flood drainage as well as method for improving water environment

Abstract

The invention discloses an embankment integrating functions of river closure, regulation and storage flood drainage as well as a method for improving a water environment. The embankment integrating functions of river closure, regulation and storage flood drainage comprises a box culvert and a storm sewage inlet tube; the box culvert comprises a box culvert top plate, a box culvert bottom plate, an upstream side wall and a soil blocking side wall; the box culvert top plate and the box culvert bottom plate are transversely arranged; the upstream side wall and the soil blocking side wall are longitudinally arranged at the two sides of the box culvert top plate and the box culvert bottom plate, so that the section of the box culvert is rectangular; the upstream side wall is arranged at one side close to the river way; the soil blocking side wall is arranged at one side close to the soil layer; reinforcing parts are arranged on joints of the upstream side wall and the soil blocking side wall, and the box culvert top plate and the box culvert bottom plate; an anti-skidding front toe and anti-skidding rear toe are downwards extended from the two sides of the box culvert bottom plate; an outlet of the storm sewage inlet tube is formed in the soil blocking side wall; an overflow slot is further formed in the upstream side wall. The method for improving the water environment can be applied to greatly improve the water environment quality.

Description

technical field [0001] The invention relates to the technical field of urban water engineering facilities, in particular to an embankment with the functions of interception, storage and drainage, and a method for improving the water environment. Background technique [0002] Large densely populated cities are generally built along the banks of relatively flat rivers, while small and medium-sized towns are often built directly along the banks of small watersheds. With the development of cities and towns, various human factors lead to increased runoff intensity, increasing the pressure of flood control and drainage; at the same time, underground rainwater and sewage pipelines are dense and intricate, and it is difficult to adopt the traditional way of intercepting sewage by buried pipes before and after the river bank, and the effect is poor. affect flood drainage; the early rain interception and storage ponds that have emerged in recent years require a large piece of land, a ...
