Foundation pit dewatering system and control method
The invention provides a foundation pit dewatering system and a control method, and belongs to the technical field of foundation pit dewatering. The system comprises a master control box and a plurality of single-well control systems, and each single-well control box is connected with a corresponding water pump and a corresponding dewatering well. The master control box is used for determining the number of dewatering wells needing to pump water based on the difference value between the water level of an observation well and a water level control threshold value. The water pumping instruction is sent to single well control boxes corresponding to the first n water pumps in a preset water pump starting sequence list; wherein the preset water pump starting sequence list is determined based on a water pumping and dewatering test, the water pumps are ranked in the preset water pump starting sequence list according to the descending order of the influence degree of unit time on the water level of the observation well, n represents the number of dewatering wells needing water pumping, and n is an integer larger than zero; and each single well control box is used for controlling the water pump to start water pumping after obtaining the water pumping instruction. The precipitation amount and the water level can be accurately controlled, and the precipitation efficiency is improved.
本发明提供一种基坑降水系统及控制方法，属于基坑降水技术领域。该系统包括总控制箱和多个单井控制系统，每个单井控制箱分别和各自对应的水泵和降水井连接：总控制箱用于基于观察井的水位与水位控制阈值的差值确定需要进行抽水的降水井数量，并将抽水指令发送至预设的水泵启动顺序列表中前n个水泵对应的单井控制箱；其中，预设的水泵启动顺序列表基于抽降水试验确定，预设的水泵启动顺序列表中按照单位时间对观察井的水位的影响程度从大到小的顺序对水泵排序，n表示需要进行抽水的降水井数量，n为大于零的整数；每个单井控制箱用于在获取到抽水指令后，控制水泵启动抽水。本发明能够对降水量和水位的精确控制，并提高降水效率。
