Foundation pit dewatering control method
A foundation pit dewatering management and control method relates to the technical field of foundation pit dewatering, and comprises the following steps: dividing water level observation wells of a foundation pit into A-type water level observation wells based on foundation pit safety and B-type water level observation wells based on environmental safety according to dewatering types and arrangement positions; the upper limit value and the lower limit value of the safe water level burial depth of the A-type water level observation well are calculated according to the excavation depth of the foundation pit, the top of the target water-containing layer and the bottom of the target water-containing layer, and the B-type water level observation well is divided into a partition type B-type observation well and a non-partition type B-type observation well according to the relation of the waterproof curtain; calculating the safety water level burial depth value of the non-partition type B-type observation well according to the actual water level of the adjacent A-type water level observation well, and respectively setting the safety water level burial depth upper limit value and the safety water level burial depth lower limit value of different types of observation wells according to the calculated safety water level burial depth value of each observation well; and corresponding early warning and alarm information is output through comparison with the actual water level burial depth.
一种基坑降水管控方法，涉及基坑降水技术领域，该方法根据降水类型及布设位置将基坑的各个水位观测井分为基于基坑安全的A类水位观测井、基于环境安全的B类水位观测井，并根据基坑开挖深度及目标含水层层顶、目标含水层层底计算A类水位观测井的安全水位埋深上、下限值，根据止水帷幕的关系将B类水位观测井分为隔断型B类观测井、非隔断型B类观测井，根据相邻A类水位观测井的实际水位来计算非隔断型B类观测井的安全水位埋深值，并根据计算出来的各个观测井的安全水位埋深值分别设置不同类型观测井的安全水位埋深上、下限值，并通过与实际水位埋深的对比输出相应的预警、报警信息。
