Description

[0002] In recent years, safety accidents caused by poor construction site drainage work have occurred frequently. How to understand the rainwater situation during flood season and quickly drain water has become an important condition to ensure construction safety. Therefore, we analyze the factors affecting the drainage effect of the construction site and find that it is affected by the following factors, such as poor water pump action control accuracy, no monitoring alarm device, pipe leakage, pump or pipe blockage, etc.

[0003] There are more heavy rainfall days in summer flood season, and the difficulty of flood prevention is gradually increasing. In the infrastructure project involving shaft operation, dangerous situations such as rainwater pouring into the shaft easily occur in thunderstorm weather, which poses a hidden danger to the personal safety of on-site construction personnel. The traditional shaft sump pump drainage work is mainly based on manual supervision. Due to personnel shortage, it is not possible to divert a dedicated person to carry out drainage work, which is usually handled by some nearby positions nearby; the pain point of manual supervision is that the drainage frequency is high, and the operator must come and go to observe the water storage capacity of the water tank.

[0004] However, the operator cannot leave the post under the condition that the equipment at the post is running, which may cause water accumulation in the shaft, and the operator's attention is also dispersed, which poses a safety hazard. In addition, due to the limitation of geological conditions, the space under the shaft is very narrow, and personnel cannot easily enter and exit, and when the water tank is full or empty, it cannot be handled in time, which poses a great safety hazard.

[0005] In addition, when the rainfall increases during the flood season, a large amount of water suddenly flows into the water tank, which will exceed the normal drainage capacity of the water tank. The existing shaft drainage system cannot monitor the change of water flow and give timely warning, and it is difficult to take corresponding measures in time, which may cause safety risks and accidents.
