Embodiment Construction
[0037] In order to facilitate the understanding of the present invention, the following will be described in conjunction with the accompanying drawings and embodiments.
[0038] see Figure 1 to Figure 7 , The present invention provides a monitoring system and monitoring method for foundation pit well point dewatering. like figure 1 The well point is provided with a steel pipe 10 and a water pump 20 arranged at the bottom of the steel pipe 10 , and the monitoring system for foundation pit well point dewatering includes the water pump 20 , a pressure gauge 30 , and a terminal device 40 . in:
[0039] The water pump 20 is arranged at the bottom of the steel pipe 10, such as figure 1 , figure 2As shown, the water pump 20 has a water delivery pipe 21 connected to the outside of the steel pipe 10 for pumping the groundwater in the well point out of the well. In the present invention, the water pump 20 is also used to output a power signal to the terminal device 40 .

The invention provides a monitoring system for well point dewatering of a foundation ditch, and a monitoring method of the monitoring system. The monitoring system is provided with a steel pipe, a water pump, a pressure gauge and terminal equipment at a well point. The pressure gauge is arranged in a well and is used for converted measurement on change in a groundwater level, and the terminal equipment is arranged outside the well and is used for measuring the change of power of the water pump and for displaying the measured water level and power data, thus the water level in the well point of the foundation ditch can be monitored and adjusted according to water level data and monitored water pumping flow, the technical problems resulting from the manually measured water level are solved, and the monitoring system for the well point dewatering of the foundation ditch is simple in setting and accurate in measurement data. The monitoring system has the beneficial technical effects that the change of the groundwater level is controlled with high efficiency, manpower and material resources are saved substantially, and the working efficiency of equipment is improved.
Description
technical field [0001] The invention relates to the technical field of foundation pit well point dewatering, in particular to a monitoring system for foundation pit well point dewatering. Background technique [0002] Groundwater resources are more complex than surface water resources. Therefore, precipitation construction, changes in the quality and quantity of groundwater itself, environmental conditions that cause groundwater changes, and groundwater migration laws cannot be directly observed. At the same time, groundwater pollution and ground subsidence caused by overexploitation of groundwater are important The slowly changing type, once accumulated to a certain extent, becomes irreversible damage; therefore, the accurate development and protection of groundwater must rely on long-term groundwater monitoring to grasp the dynamic changes in time. [0003] Well point dewatering in foundation pit engineering is a method of artificially lowering the groundwater level, so it...
