Description

Wall-mounted micro drainage pump station for sewage interception engineering

Technical Field

The utility model relates to a wall-hanging miniature drainage pump station for cutting dirty engineering belongs to the drainage engineering field, in particular to sewage hoisting device that little pipe diameter drainage pipe cut dirty system and used.

Background

The urban drainage system is divided into a split system and a combined system. The split flow system is characterized in that rainwater and sewage are respectively discharged by two independent systems, the rainwater is discharged into water bodies such as rivers, and the sewage is collected by a pipeline and discharged into a sewage plant for treatment and then discharged into the water bodies. The confluence system is that rainwater and sewage are collected by adopting a system, sewage is intercepted before being discharged into a water body, the sewage is discharged to a sewage plant through a sewage intercepting pipeline for treatment, rainwater and sewage are converged in rainy days, the flow exceeding the designed sewage intercepting amount of the sewage intercepting pipe is directly discharged into the water body, and the manufacturing cost of the confluence pipe is relatively low. In the early construction stage of many cities, a combined drainage system is adopted due to population, capital and other problems, and some cities are directly drained into a water body even without sewage interception. In the initial stage of construction, the pollution to the water body is not serious due to less population, and the attention is not paid. With the development of economy, a large amount of sewage is directly discharged into a water body to cause pollution, and people return to the water body again to carry out environmental treatment.

Today continuously attach importance to environmental protection, drainage pipe cuts dirty transformation all being carried out in many cities, lays at the bank of waters such as river course, drainage channel and cuts dirty pipeline, sets up at the position that the confluence pipeline was arranged to the water and cuts dirty well, and no rain weather cuts off sewage and discharges into and cuts dirty pipeline. However, in practical engineering, many converging pipelines are limited by terrain and cannot be provided with a sewage interception well, such as: river channels are protected and built, buildings on two sides are built close to the river channels, drain pipes are directly arranged to the river channels from the buildings or narrow roadways, the pipe diameters of the drain outlets are small, and most of the drain outlets are water outlets for residents of one family, and the drain outlets are directly arranged into the river channels. For the sewage interception of the water outlets, a sewage interception pipeline is constructed on the shore of the canal, and a pipe can be hung on the protective wall of the river canal. In the prior art, a method for hanging a pipe on a protective wall of a river channel is adopted, a bracket welded by angle steel is arranged on the protective wall of the river channel, a sewage intercepting pipeline is arranged on the bracket, and a water outlet is connected with the sewage intercepting pipeline.

Because the sewage interception pipeline is connected into the downstream sewage pipeline and is limited by the height of the sewage pipeline connected into the downstream sewage pipeline, the sewage interception pipeline of the hanging pipe is constructed according to the designed elevation, a certain lower water outlet is lower than the sewage interception pipeline, and the sewage interception pipeline cannot be connected into the sewage interception pipeline in a self-flowing manner. Because the pipe diameter of the outlet of a family is less, and the flow is little, generally can not set up the pump station at the outlet, even the integrated pump station volume of prior art is also great, in actual engineering, the general way is that the flow is less, does not cut off and directly discharges into the river course, causes not cutting dirty direct discharge. The slightly lower water outlet may be connected to the sewage intercepting pipeline via an upward turned pipe and turned water flows into the sewage intercepting pipeline via water pressure.
