Foundation pit excavation graded precipitation device and method
The invention discloses a foundation pit excavation graded precipitation device and method, and relates to the field of drainage of foundation pit excavation. The problems that automatic graded precipitation cannot be realized, the efficiency is low and the safety around a foundation pit is influenced in the prior art are solved. According to the key point of the technical scheme, the foundation pit excavation graded precipitation device comprises a precipitation well, a water pumping device, a water level monitoring device and a control device; the control device is electrically connected with the water level monitoring device and the water pumping device; and a water inlet of the pumping device is located below the liquid level of the precipitation well. The foundation pit excavation graded precipitation method comprises the following steps that according to the requirement of graded excavation, a needed liquid level value is calculated; an initial liquid level value is measured; a highest liquid level value and a lowest liquid level value are set; when the liquid level value is greater than or equal to the highest liquid level value, the water pumping device is started; and when the liquid level value is smaller than or equal to the lowest liquid level value, the water pumping device is closed. Excessive settlement caused by sudden drop of the underground water level around the foundation pit is effectively reduced, and safety of buildings around the foundation pit is guaranteed.
本发明公开了一种基坑开挖分级降水装置及方法，涉及基坑开挖排水领域，解决了现有技术不能实现自动化的分级降水、效率低、影响基坑周边安全的问题。其技术方案要点是：一种基坑开挖分级降水装置，包含降水井，还包含抽水装置、水位监测装置、控制装置；控制装置与水位监测装置，控制装置与抽水装置电连接；抽水装置进水口位于降水井液面下。一种基坑开挖分级降水方法，包含如下步骤：根据分级开挖的要求，计算所需的液位值；测量初始液位值；设定最高液位值与最低液位值；当液位值大于等于最高液位值，启动抽水装置；当液位值小于等于最低液位值，关闭抽水装置。有效减少基坑周边因为地下水位过大骤降带来的过大沉降，保证基坑周边建筑安全。
