The invention discloses a debris-retaining and backflow-preventing intercepting well with the sewage flow controllable.The debris-retaining and backflow-preventing intercepting well comprises an intercepting well structure.A draining port of the intercepting well structure is connected with a natural water body.A fixed weir is arranged in the intercepting well structure.A swage intercepting port is formed in the portion, between a water inlet of the intercepting well structure and the fixed weir, of the side wall of the intercepting well structure.An intercepting device capable of controlling the sewage flow is arranged at the swage intercepting port.A debris retaining device is arranged between the swage intercepting port and the fixed weir.A backflow preventing device is arranged at a draining port of the fixed weir or the draining port of the intercepting well structure.The debris-retaining and backflow-preventing intercepting well is simple in structure, the debris retaining function of the intercepting well and accurate control over the sewage flow can be achieved, and meanwhile downstream water can be prevented from flowing back.
Description
technical field [0001] The invention relates to an interception well, which belongs to the technical field of water supply and drainage systems, in particular to an interception well with controllable sewage flow and slag-stopping and anti-backflow prevention. Background technique [0002] In the combined pipeline system in urban drainage projects in our country, interception wells have existed for a long time. However, the previous interception well cannot realize the function of slag blocking, and the flow of sewage flowing to the sewage pipe cannot be controlled. At the same time, when the downstream water level rises above the elevation of the upstream pipe top, it will cause downstream water backflow. Therefore, there is an urgent need for a new type of interception well technology that can not only realize slag retention and precise control of sewage flow, but also prevent downstream water backflow.
