Description

Intercepting well capable of reducing sludge blockage

Technical Field

The utility model relates to a vatch basin field especially relates to a reduce vatch basin that silt blockked up.

Background

In the early urban construction process of old urban areas in China, due to the lack of advanced design ideas of drainage systems, drainage systems of the old urban areas are all in a rain and sewage confluence mode, and a plurality of sewage straight drainage openings exist in river channels in the old urban areas. With the continuous and deep innovation of our country, the social economy has a rapid development, and the requirements of residents on the surrounding environment are higher and higher. In order to improve the environment around urban residents, the nation vigorously carries out actions of eliminating urban black and odorous water, improving the quality and the efficiency of a pipe network and the like, and a large number of straight discharge openings along a river are regulated. In the renovation process, two ways of 'distribution of rain and sewage transformation' and 'mixed flow interception' are mainly adopted, wherein a large amount of manpower and material resources are consumed in the distribution of rain and sewage transformation, so that the interception mode is adopted in the drainage port renovation process of the river channel in most cities.

The drainage cut-off mode is adopted, two types of cut-off wells are mainly adopted, namely a groove type cut-off well and a weir type cut-off well, the sewage cutting pipes of the two types of cut-off wells are located at the lowest positions, and all the sewage cut-off in the rainwater pipes directly enters a sewage pipeline. Rainwater pipelines are usually connected with a large number of rainwater grates and rainwater openings, so that a large amount of sludge can be stored in the rainwater pipelines. After damming through the above two types of catch basins, all silt can directly enter the sewage pipe network, and the sewage pipe network can be frequently blocked.

In the intercepting process of the rainwater pipe network, after the interception is carried out through a common intercepting well, sewage flows into the intercepting well through a rainwater pipe, and all the sewage enters the intercepting pipe because the intercepting pipe is located at the lowest point. When silt in the rainwater pipe enters the intercepting well, all silt can also enter the intercepting pipe together because a sand sediment trap is not arranged, so that the sewage pipe is blocked. When the intercepted sewage directly and completely enters the sewage pipe network, the silt and the garbage in the sewage can be brought into the sewage pipe network, and the sewage pipe network is blocked.

(1) in sunny days, water (basically sewage) in the rainwater inlet pipe flows into the sedimentation area, and after sludge is precipitated in the sedimentation area, the water overflows to the sewage intercepting pipe through the water retaining weir and then flows into the sewage pipe network through the sewage intercepting pipe.

(2) During the initial stage of raining and the period of raining, water (a part of sewage and a part of rainwater) in the rainwater inlet pipe flows into the precipitation zone, after sludge is precipitated in the precipitation zone, overflows to the sewage intercepting pipe through the water retaining weir, and then flows into a sewage pipe network through the sewage intercepting pipe.

(3) During heavy rain, water (mostly rainwater, small part sewage) in the rainwater inlet pipe flows into the precipitation zone, and because of the great water flow in the rainwater inlet pipe, the displacement that leads to cutting dirty pipe can not satisfy the drainage demand, and most rainwater can directly flow into the rainwater outlet pipe, finally flows into external environment. At the moment, the rainwater inlet pipe has large water flow, partial silt in the precipitation area can be flushed into the rainwater outlet pipe by the rainwater to be discharged into the external environment, and blockage caused by untimely cleaning of the silt is avoided.
