Permeation type automatic reset rainwater flow abandoning well

Abstract

The invention discloses a permeation type automatic reset rainwater flow abandoning well, and belongs to the technical field of rainwater flow abandoning wells. The permeation type automatic reset rainwater flow abandoning well comprises a well body, a water inlet pipe, an overflow pipe, a flow intercepting pipe, a partition plate, a support rod, a frame support, a container device and a spring. The well body is provided with a water inlet, an overflow port and a flow intercepting port. The partition plate is horizontally arranged in the well body and provided with a hole. The frame support isarranged under the hole and fixedly connected with the partition plate through the support rod. The frame support is provided with a through hole for a long connecting rod to penetrate. The containerdevice comprises a container wall, a container support rod, water permeation concrete and the long connecting rod. The top of the container wall is lower than the lowest position of the water inlet and the overflow port. The outer diameter of the container wall is larger than the diameter of the hole. The container support rod is arranged at the bottom in the container wall, and the water permeation concrete is laid on the container support rod. The spring sleeves the long connecting rod and is located between the container support rod and the frame support. By means of the permeation type automatic reset rainwater flow abandoning well, early-stage dirty rainwater flow abandoning and later clean rainwater continuous collection can be achieved, and the later rainwater flow abandoning amount can be reduced as well.

Description

Technical field [0001] The invention relates to a rainwater abandonment well, in particular to a permeable automatic reset rainwater abandonment well, belonging to the technical field of rainwater abandonment wells. Background technique [0002] In the early stage of rainfall, when rainwater falls to the ground, it will contain a lot of impurities such as sediment, particulate matter and floating matter. It is often necessary to intercept the initial rainwater with abandoning device or abandoning well, 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 cleaner rainwater in the later stage of the rainfall, resulting in too much rainwater discarded in the later stage of the rainfall, which not only greatly wastes resources but also increases sewage treatment The plant handles the burden of cleaner rainwater. In addition, the e...

Problems solved by technology

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
