Drainage well structure with layered energy dissipation function and drainage method
The invention provides a drainage well structure capable of dissipating energy in a layered mode and a drainage method. A flow collecting assembly comprises at least one rain and sewage collecting pool which is arranged on the peripheral side of a vertical shaft and communicates with the vertical shaft. The rainwater and sewage collecting pool collects and filters water and inputs the water into the vertical shaft; the layered energy dissipation assembly comprises a plurality of retaining walls and partition plate assemblies which extend in the vertical direction and are annularly arranged on the peripheral side of the upper portion of the lower well body. A gap is formed between every two adjacent retaining walls, and a water passing gallery is formed between each retaining wall and the inner wall of the vertical shaft; the partition plate assembly comprises a stand column extending in the vertical direction and multiple stages of partition plates. The multiple stages of partition plates are arranged at intervals in the vertical direction and arranged outside the stand column in a sleeving mode. A water drop hole for water to pass through is formed in the partition plate; the regulation and storage assembly is used for regulating the flow state and flow velocity of the water body and then introducing downstream. On the premise that the drainage capacity is met, water falling potential energy is greatly eliminated in a spatial and multi-stage mode, and damage caused by impact force of drainage in a large-flow and high-depth drainage well to the interior of the drainage well is effectively avoided.
本申请提出一种分层次耗散能量的排水井结构及排水方法，集流组件包括至少一个设置在竖井周侧且与竖井连通的雨污收集池；雨污收集池收集水体过滤后输入竖井内；分层消能组件包括多个在竖直方向延伸且环设下井体上方周侧的挡墙和隔板组件；其中相邻的挡墙之间有间隙且挡墙与竖井的内壁之间形成过水廊道；隔板组件包括沿竖直方向延伸立柱和多级隔板；多级隔板在竖直方向上间隔设置并套设在立柱外部；隔板上开设用于水体通过的跌水孔；调蓄组件用于调整水体的流态和流速后通入下游。本申请在满足排水能力的前提下，分空间、多阶段地大幅度消除水体跌落势能，有效地避免大流量、高深度排水井内排水对排水井内部的冲击力造成的损坏。
