Problems solved by technology
[0004] In the interception and storage system, the inflow speed of the traditional inflow well is too fast, which has a large impact on the storage pipe, which is easy to damage the storage pipe and affects the rapid inflow of initial rain, resulting in overflow of the upstream of the pipe and affecting rainwater collection.

The invention discloses an energy dissipating well for initial rainwater in an ultra-deep storage adjustment pipe. The energy dissipating well comprises a well body, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is communicated onto the side wall at the upper part of the well body; the water outlet pipe is communicated to the lower part of the well body; and a step-shaped energy dissipating sill is also arranged in the well body and spirally connected to the lower side of the water inlet pipe. The energy dissipating well is simple in structure, convenient and practical, has a good energy dissipating effect on the rainwater and the like entering into the well body, and greatly reduces the impact of the rainwater on the lower part of the well body and the storage adjustment pipe.
Description
technical field [0001] The invention relates to the technical field of urban drainage, in particular to an energy-dissipating well for initial rainwater inflow of an ultra-deep regulating storage pipe. Background technique [0002] With the development of industrial economy and the discharge of waste water in people's daily life, the rivers in many cities have been seriously polluted, and this phenomenon is common throughout the country. [0003] In order to prevent river pollution, it is necessary to collect initial rainwater and dry sewage. The common method is to intercept the sewage before draining into the river. However, due to the limited capacity of the interception pipeline along the coast, overflow is likely to occur in rainy days, which seriously pollutes the river. Therefore, it is necessary to intercept and store the initial rainwater to reduce pollution to the river. [0004] In the interception and storage system, the inflow speed of the traditional inflow we...
