Abstract

The invention relates to the technical field of municipal engineering, in particular to a flow dividing well. The flow dividing well comprises a flow dividing well body and an overflowing weir, an overflowing groove is formed by the connection of the overflowing weir and the flow dividing well body, a closure groove is formed by the outer side wall of the overflowing weir and the flow dividing well, the side wall of the flow dividing well body is connected with an upstream rain water inlet pipe, a downstream water outlet pipe, a standard-exceeding rain water outlet pipe and an initial rain water closure pipe, the upstream rain water inlet pipe, the downstream rain water outlet pipe and the initial rain water closure pipe are communicated with the closure groove respectively, and the standard-exceeding rain water outlet pipe is communicated with the overflowing groove. The flow dividing well has the advantages that initial rain water collection, middle stage rain water emission and standard-exceeding rain water storage can be achieved, the well is particularly suitable for accumulated water treatment engineering with limited downstream pipeline scale, the problem of waterlogging water accumulation under the condition of limited drainage capability of downstream pipelines is solved, the pollution of the downstream water body of the initial rain water is reduced, and regional rainwater utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a diversion well. Background technique [0002] With the rapid development of urbanization and the increase of hardened road surfaces, the problem of urban waterlogging has gradually become prominent, and many cities in my country have serious waterlogging problems. Waterlogging and stagnant water control projects are often limited by site conditions or project investment and cannot solve the expansion of the drainage pipe network in the entire catchment area at one time. In order to meet the requirements of waterlogging prevention and control, the diameter of the drainage pipeline in the reconstruction section needs to be enlarged, which may easily cause upstream reconstruction. The elevation of the finished drainage pipe is lower than that of the rainwater pipeline in the downstream unrenovated section, which may easily cause poor drainage and blockage of the pipe...
