Problems solved by technology

[0002] There are five major disadvantages in the existing foundation pit deep tube well dewatering technology: 1. The existing technology cannot monitor the groundwater level change accurately in real time. For foundation pit dewatering projects with special or high technical requirements, it can only be achieved by increasing the frequency of manual detection Require
Not only labor-intensive, but also a huge safety hazard
2. The existing technology can only manually control the water pump switch to control the groundwater level, which cannot effectively control the displacement, nor can it stabilize the groundwater level at the bottom of the basement and the precipitation curve around the foundation pit in a short time
3. In the process of precipitation, the existing technology lacks data monitoring and statistics, human subjective factors are greatly affected, and lack of scientific rigor
4. Lack of monitoring of the operation of the equipment, resulting in a high maintenance rate of the equipment
5. Cannot scientifically and effectively control power consumption
