Description
Technical Field
The invention relates to a drainage-assisting intercepting well, and belongs to the technical field of urban drainage pipe network systems.
Background
Catch basins are used in combined rain and sewage systems for the purpose of separating rain and sewage. In dry seasons, only sewage is contained in the pipe, the intercepting well can intercept the sewage and flow the sewage into a newly-built sewage pipe, in rainy seasons, part of rainwater and the sewage are intercepted and flow into the sewage pipe, and the rest of rainwater overflows through a weir in the well and continues to flow downstream.
At present, the municipal drainage network system is generally divided into two types: a combined drainage pipe network and a split drainage pipe network. The combined drainage system has two main functions, namely intercepting sewage in sunny days to minimize the sewage entering a water body, and discharging flood in rainy days. However, although the existing intercepting well can discharge flood in rainy days through the intercepting main pipe, the flood discharge capacity is reduced due to the fact that the liquid level in the intercepting well rapidly rises under the extreme rainstorm condition and the intercepting capacity exceeds the maximum intercepting capacity when the gravity discharges, and the flood discharge risk of an upstream service area is often caused. For this reason, some intercepting wells are provided with drainage pumps to improve flood discharge capacity, but the drainage pumps are usually large in size, and have higher requirements on the size of the intercepting well, and the large-size pumps have higher requirements on installation and maintenance. In addition, because a channel can not be shared by natural flood discharge and drainage-assisting flood discharge, a drainage pipeline needs to be separately arranged for the drainage pump, so that not only is the land and the space occupied, but also the complexity of the urban rainwater pipeline system is increased.
