A permeable automatic reset rainwater abandonment well

Abstract

The invention discloses a permeable automatic reset rainwater abandonment well, which belongs to the technical field of rainwater abandonment wells. The invention includes a well body, a water inlet pipe, an overflow pipe, an intercepting pipe, a baffle, a support rod, a bracket, a container device, and a spring. Inside the body, there are openings on the partition; the bracket is located directly below the opening and is fixedly connected with the partition through the pole, and the bracket is provided with a through hole for the long connecting rod to pass through; the container device includes the container wall, Container struts, permeable concrete and long connecting rods, the top of the container wall is lower than the lowest position of the water inlet and overflow, the outer diameter of the container wall is larger than the diameter of the opening, the container struts are set at the bottom of the container wall, and the permeable concrete is laid On the support rod of the container; the spring is sleeved outside the long connecting rod and is located between the support rod of the container and the bracket. The invention can not only realize the discarding of dirty rainwater in the early stage and the continuous collection of cleaner rainwater in the later stage, but also reduce the discarding flow of rainwater in the later stage.

Description

technical field [0001] The invention relates to a rainwater abandonment well, in particular to a permeable automatic reset rainwater abandonment well, which belongs to the technical field of rainwater abandonment wells. Background technique [0002] In the early stage of rainfall, the rainwater will contain a large amount of impurities such as sediment, particulate matter and floating objects after it falls to the ground. It is often necessary to intercept the initial rainwater by means of abandonment devices or abandonment wells, so that the initial rainwater can be discharged to the sewage treatment plant for treatment. However, the existing rainwater abandonment wells can only intercept the initial rainwater, and cannot collect the relatively clean rainwater in the later period of rainfall, resulting in too much rainwater abandonment in the later period of rainfall, which not only wastes resources but also increases sewage treatment. The burden on the plant to treat clean...

However, the existing rainwater abandonment wells can only intercept the initial rainwater, and cannot collect the relatively clean rainwater in the later period of rainfall, resulting in too much rainwater abandonment in the later period of rainfall, which not only wastes resources but also increases sewage treatment. Burden of treating cleaner stormwater

In addition, the existing rainwater abandonment wells have a complex structure and have special requirements for the shape and structure of the well body itself. When the construction method of rebuilding old wells is used to construct rainwater abandonment wells, it takes a lot of manpower and financial resources, and the cost is high and Inconvenient to maintain
