Description

Intelligent foundation pit dewatering and pressurizing recharging system suitable for seashore tidal zone Technical Field The utility model relates to the technical field of foundation pit dewatering, in particular to an intelligent foundation pit dewatering and pressurizing recharging system suitable for a seashore tidal zone. Background At present, urban construction in China is rapidly developed, and urban problems such as dense population, traffic jam and the like are increasingly prominent. With the continuous advancement of urban areas, underground space utilization is becoming increasingly mainstream, and underground structure depths are also continuously extended downwards. The foundation pit dewatering is an important process in deep foundation pit excavation operation, and under the conditions that the depth of the foundation pit is continuously increased and the dewatering requirement is continuously improved, enough dewatering wells or other dewatering equipment are required to be arranged to reduce the water level in order to ensure the safety of the open excavation foundation pit. However, at present, the observation means for precipitation of the deep foundation pit is mainly through naked eye observation of constructors, and a precipitation well is started after ponding occurs at the bottom of the foundation pit. The quantity of the dewatering wells is started, and the opening time period of the dewatering wells is judged subjectively, so that the engineering efficiency is extremely low. In addition, for coastal city coast tidal zones, under the dynamic water environment, the foundation pit water level can be changed continuously along with the fluctuation of tides, and the foundation pit precipitation is more prone to the conditions of untimely precipitation and insufficient water-lowering and draining depth only by artificial observation, so that the construction safety problem is induced.
