Multifunctional flow-dividing well

Abstract

The invention discloses a multifunctional flow-dividing well which comprises a well body with a sealed lower part, wherein the well body is divided into a water inlet zone, a water collecting zone and a water outlet zone by a first partition board, a second partition board and a third partition board, and the first partition board, the second partition board and the third partition board are arranged in a Y shape. The water inlet zone is formed by the first partition board, the second partition board and a well wall. The water collecting zone is formed by the second partition board, the third partition board and a well wall. The water outlet zone is formed by the third partition board, the first partition board and a well wall. A water inlet pipe, a water collecting pipe and a water outlet pipe are arranged on the well walls corresponding to the water inlet zone, the water collecting zone and the water outlet zone respectively. The second partition board is lower than the first partition board, the third partition board and the well walls, and a sewage drain opening is formed in a position, in contact with a well bottom, of the lower part of the first partition board. The multifunctional flow-dividing well has the functions of primarily abandoning flow, dividing flow, draining overflowing water, dredging and the like; a rainwater inspection well does not need to be arranged; no special requirement for the arrangement of a zonal drain pipeline is needed.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and utilization, in particular to a multifunctional diversion well. Background technique [0002] In recent years, with the decrease of global water resources, the effective use of rainwater has been widely concerned. In the specific engineering design, the following conditions need to be met: [0003] 1. The rainwater that enters the diversion well during the initial period of rainfall is of poor water quality and flows directly out of the diversion well from the outlet pipe instead of entering the collection pipe, that is, the diversion well should have the function of initial rainwater abandonment; [0004] 2. Collect a certain amount of rainwater with better water quality during a rainfall, and flow it into the storage tank through the collection pipe, that is, the diversion well should have the diversion function of rainwater; [0005] 3. After the pool is full, the water level ...

Problems solved by technology

[0006] 4. The outlet pipe should have the dual functions of receiving initial rainwater and overflow rainwater, and the drainage of initial rainwater should not have special technical requirements for the drainage pipeline in the area, otherwise, the layout cost of the drainage pipeline will be greatly increased;

[0010] The existing rainwater wells cannot fully meet the various conditions mentioned above. Multiple single-function wells are often combined, which is very expensive, and often cannot be installed due to site constraints, so that the rainwater cannot be completely and conveniently realized. use
