Description

A diversion well with an overflow weir and a drainage system including the diversion well

technical field

The utility model belongs to the technical field of drainage, in particular to a diversion well with an overflow weir and a drainage system comprising the diversion well.

Background technique

At present, the drainage system of cities and buildings mainly includes diversion system, confluence system and mixed flow system, the main purpose of which is to realize the collection, transportation and treatment of water bodies. For example, a system that treats all wastewater in one way is called combined. It has only one drainage system, called the confluence system, and its drainage pipe is called the confluence pipe. The system that treats different types of wastewater in different ways is called the diversion system, which generally has two drainage systems. One can be called a rainwater system, which is used to collect rainwater and industrial wastewater with a very low pollution level that is directly discharged into the water body without treatment, and its pipeline is called a rainwater pipeline. The other can be called a sewage system, which collects domestic sewage and industrial wastewater that needs to be treated before it can be discharged, and its pipeline is called a sewage pipeline. The mixed flow system is a system between the diversion system and the confluence system. It is mainly due to the misconnection and mixing of pipelines in the area of the diversion system, which leads to the occurrence of different types of wastewater in some pipelines, that is, rainwater pipes or sewage. The pipes actually become confluent pipes. Wastewater in urban sewage pipes and combined pipes is often collectively referred to as urban sewage.

With the emergence of modern housing sanitation equipment and high-rise buildings, the population is dense, and the excrement is transported by water, which greatly increases the intensity of urban sewage; coupled with the development of industry, the industrial wastewater has increased greatly, and the rivers and lakes near the city have intolerable pollution. . Therefore, a sewage treatment plant was added, and various water outlets were connected with pipes, and the wastewater in each main drainage pipe was collected into the sewage treatment plant for treatment, forming an intercepting confluence system. The pipeline that connects the water outlet and intercepts the waste water to the sewage treatment plant is called the interception pipeline or sewage interception pipeline.

When it rains, the amount of waste water increases sharply. If all the waste water is intercepted, the interception pipeline and the sewage treatment plant will inevitably need a large scale, which will increase the engineering cost too much. Therefore, the inspection well at the intersection of the main drainage pipe and the interceptor pipe is generally replaced with a shunt well. The structure of the diversion well can have different designs, but the current design is not perfect, and there is no improvement for different sewage and rainwater quantities. In the dry season, there is only sewage in the pipe, and the diversion well can intercept the sewage and flow to the sewage pipe; in the rainy season, part of the rainwater and sewage are intercepted and flow into the sewage pipe, and the rest of the rainwater overflows through the weir in the well and continues to flow downstream. For the flow direction of rainwater and sewage, most of the current control methods use water level or rainfall to control, but the existing water level control method or rainfall control method is not very good for the diversion control of rainwater and sewage, thus losing the diversion The meaning of well existence.
