Foundation pit construction recharge well structure
The invention discloses a recharge well structure for foundation pit construction, which belongs to the technical field of building construction and comprises a recharge well body, a plurality of groups of holes are formed in the well wall of the recharge well body along the extension direction of the recharge well body, and a water injection core pipe for injecting water is arranged on the inner side of the recharge well body. The water injection core pipe extends into the recharge well body, the lower end of the water injection core pipe is closed, and the upper end of the water injection core pipe is connected to a hydraulic loading device; two movable sealing assemblies are fixed to the lower portion of the water injection core pipe in a spaced mode and can expand after the water injection core pipe reaches a designated position, so that a gap between the water injection core pipe and the inner wall of the recharge well body is sealed, and a water injection hole is formed in the position, between the two movable sealing assemblies, of the water injection core pipe. According to the recharge well, recharge can be conducted on stratums at different depth positions so as to meet the site construction requirement, the construction period is greatly shortened, and cost is saved.
本发明公开了一种基坑施工回灌井结构，属于建筑施工技术领域，包括回灌井体，沿着所述回灌井体的延伸方向在回灌井体的井壁上开设有若干组开孔，所述回灌井体的内侧设置有用于注水的注水芯管，所述注水芯管深入到所述回灌井体内，所述注水芯管的下端封闭，所述注水芯管的上端连接至水力加载装置；所述注水芯管的下部间隔固定有两组活动密封组件，所述活动密封组件能够在注水芯管到达指定位置后膨胀，从而将注水芯管和回灌井体内壁之间的间隙进行密封，位于两组活动密封组件之间在所述注水芯管上开设有注水孔。本发明回灌井可以针对不同深度位置的地层进行回灌，以适应现场的施工需求，大大缩短了施工周期，节约了成本。
