Temporary drainage construction process for large-pipe-diameter river channel crossing pool body construction

Abstract

The invention relates to the technical field of large-pipe-diameter riverway crossing pool body construction, in particular to a temporary drainage construction technology for large-pipe-diameter riverway crossing pool body construction. The method specifically comprises the following steps of surveying and setting out, plugging upstream and downstream culvert mouths, newly building box culverts on the upstream and the downstream, erecting drainage pipes, treating drainage pipe connectors, detecting and inspecting the drainage pipes, and removing upstream plugging measures. By means of the temporary drainage construction technology for the storage pond, the problems that in the prior art, when a water treatment complex is built in an existing drainage system for closure, the rainfall is huge in the rainy season or in the rainstorm weather when upstream water flow is drained to the downstream through a submersible sewage pump, and the water pumping and drainage capacity of the submersible sewage pump is limited can be effectively solved; the problems that rainwater overflows, urban waterlogging is caused, and personal and property safety is harmed due to the fact that actual requirements cannot be met are solved, and water can be effectively and directly drained to the downstream box culvert through the drainage pipe.

Description

technical field [0001] The invention relates to the technical field of storage pond construction, in particular to a temporary drainage construction process involving a large-diameter river channel crossing the pond body. Background technique [0002] In today's society, although the economy is developing rapidly, the ecology has also been damaged to a certain extent, resulting in frequent occurrence of severe weather. Therefore, the construction of urban water treatment complexes is currently a major direction for mitigating storm disasters and rational utilization of water resources. Among them, the construction of storage tanks is used to reduce flood peak flow, reduce the diameter of downstream rainwater main pipes, and improve regional drainage standards and Flood control capability and reduction of waterlogging disasters are the main measures. And building a storage tank in the existing drainage system is a way to save the project cycle and save manpower and economic ...
