Flood diversion equipment and method of using flood diversion equipment to solve urban waterlogging

Abstract

The invention belongs to the sponge city construction flood diversion and flooded field draining technical field and discloses a vertical flood diversion blind shaft drainage technology, in particular, a flood diversion device and a method for solving urban waterlogging by using the same. The flood diversion device and the method of the invention have the advantages of low investment, simple facilities, simple operation and high sustainability. With the flood diversion device and the method of the invention adopted, the sufferings of urban residents caused by floods can be eliminated, and personal safety and property safety of people of cities attacked by waterlogging can be effectively protected; after the flood diversion device is built, operation and maintenance costs are basically not required. The flood diversion device and the method are applicable to flood control and drainage in regions which are vulnerable to waterlogging disasters, such as cities, villages, factories, mines, institutions, roads and railways. The method includes the following steps that: flood diversion amount of a region is calculated according to underground hydrologic conditions, historical waterlogging conditions of the region and urban flood draining ability; and the total amount of flood diversion facility construction, the number of individual facilities and the volume of the individual facilities are determined; and vertical flood diversion blind wells and auxiliary facilities are constructed.

Description

technical field [0001] The invention relates to the technical field of urban flood control and drainage, in particular to a low-investment, simple-equipment, easy-to-operate, high-sustainability solution that can effectively solve the suffering of urban residents suffering from floods for many years and effectively protect the lives and properties of people in disaster-prone areas. Safety. After completion, there is basically no need for operation and maintenance costs. It is suitable for flood control and drainage equipment wells for flood control and drainage in cities, villages, factories, mines, institutions, highways, railways and other areas that are easily submerged by rainwater, and the method of using flood diversion equipment to solve urban waterlogging. Background technique [0002] Urban waterlogging refers to the phenomenon of flooding disasters in cities caused by heavy or continuous rainfall exceeding the city's drainage capacity. The objective cause of water...

AI Technical Summary

Problems solved by technology

In some cities in China, the pipelines are aging, the design drainage capacity does not match the actual flood volume, the drainage facilities are not perfect, and the construction of the drainage system is lagging behind, which is an important cause of waterlogging

In addition, a large number of hard pavements in cities, such as a large number of asphalt roads and cement pavements, have poor water permeability during rainfall, are not easy to infiltrate, and are easy to form pavement water

[0003] At present, some people at home and abroad suggest to build some temporary water storage regulating tanks and regulating tanks, and then carry out secondary drainage after the flood peak. This not only requires huge manpower and financial resources, but also makes maintenance difficult in the later stage. More importantly, the torrent caused by heavy rain And temporary storage water is directly discharged into the water without treatment, which will cause serious water pollution to the water system
