(1) The water level is not controllable
The traditional well point method dewatering directly places a water pump to the bottom of a well without any control measures, and the situation that the water level is too fast in the early stage and is over-limited in the later stage often occurs when the underground water level is pumped to the bottom without external force intervention, so that the peripheral ground is easy to settle; and simultaneously, the water pumping and draining amount and the resource loss are increased.
(2) Great manpower input
The conventional equipment management method frequently adopted in pumping operation is to arrange a specially-assigned person for 24-hour duty patrol, test and record water level data at any time, and has the disadvantages of large investment of human resources, large workload and untimely and inaccurate grasp of underground water level change conditions.
(3) High failure rate of water pump
In the process of pumping water, the water pump can be continuously switched between a full-load state and an idle-load state, and a water pump motor is easy to damage, so that precipitation is interrupted, the underground water level rises again, the precipitation efficiency is influenced, and the equipment cost is increased.
