Integrated automatic intercepting well and intercepting method

Abstract

The invention provides an integrated automatic intercepting well and an intercepting method. The integrated automatic intercepting well comprises a well body, a water inlet pipe, a sewage intercepting pipe and an overflow pipe, wherein the water inlet pipe, the sewage intercepting pipe and the overflow pipe are arranged on the well body; the upper end of the well body is detachably connected with a well lid, the lower end of the well body is provided with a base, and the well body, the well lid and the base form a closed intercepting cavity; the intercepting cavity is provided with a basket grating structure, a sewage intercepting valve and an overflow valve; the basket grating structure is located at a pipe opening of the water inlet pipe; the sewage intercepting valve is located at a pipe opening of the sewage intercepting pipe; and the overflow valve is located at a pipe opening of the overflow pipe. According to the integrated automatic intercepting well and the intercepting method, the two valves which are different in structure and are hydraulically controlled are adopted for controlling the flow of the sewage intercepting pipe and the flow of the overflow pipe respectively, automatic adjustment is conducted according to the water level conditions of the valves, and then the effects of efficient sewage intercepting and high-precision sewage intercepting amount control are achieved; and meanwhile, the method is high in integration, simple in structure, convenient to control, stable in cut-off amount and easy to construct.

Description

technical field [0001] The invention relates to the technical field of drainage pipe networks, in particular to an integrated automatic interception well and an interception method. Background technique [0002] The interception well is used in the rain and sewage combined system to separate the rain and sewage. In the dry season, there is only sewage in the pipe. The interception well can intercept the sewage and flow into the sewage pipe. In the rainy season, part of the rainwater and sewage are intercepted and flow into the sewage pipe. The rest of the rainwater overflows through the weir in the well and continues to flow downstream. [0003] In recent years, pipeline sewage interception reconstruction projects have been built all over the country. The urban dry season sewage and early rainwater in the rainy season are intercepted into the sewage interception pipe through the interception well and then discharged to the sewage pipe network, so as to realize the separation...
