Problems solved by technology

[0002] During the dewatering construction of the project, the traditional method uses a large number of manual garrisons to check the water level of the dewatering well. When the water level drops to the design elevation, the power is turned off, and when the water level exceeds the design water level, the power is turned off again.... Repeatedly, until the whole project is dewatered The construction of the project is completed. During this process, a large number of personnel are required to inspect the site, resulting in a large waste of human resources.

Embodiment Construction

[0012] The present invention is further illustrated below by specific examples.

[0013] like figure 1 , figure 2 Shown, a kind of automatic control method of dewatering well power supply, comprises

[0014] Step 1, install an automatic control switch 3 on the power line 2 of each dewatering well water pump 1,

[0015] Step 2, set the upper and lower limits of the water level to the automatic control switch 3,

[0016] Step 3, connect the power supply for the automatic control switch 3 .

[0017] In the automatic control method of the power supply of the dewatering well, the automatic control switch 3 includes a hollowed-out metal drum 31, a pressure-sensitive switch 32 is arranged on the top of the inner wall of the metal drum 31, and a floating switch 32 is arranged below the pressure-sensitive switch 32. Ball 33, the floating ball 33 is also located in the metal cylinder 31; when the water level rises, the floating ball 33 rises thereupon to generate pressure on the pr...

Abstract

The invention aims to overcome the above shortcomings and provides an automatic control method for a power supply of dewatering wells. The automatic control method is characterized by comprising the steps of 1, installing an automatic control switch on a power supply line of a water pump of each dewatering well; 2, setting an upper water level limit and a lower water level limit for the automaticcontrol switches; and 3, connecting the automatic control switches to a power supply. The automatic control method can simultaneously perform automatic control on multiple dewatering wells through adopting the automatic switches, and thus can liberate a lot of manpower resources and improve the operation efficiency.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an automatic control method for a precipitation well power supply. Background technique [0002] During the dewatering construction of the project, the traditional method uses a large number of manual garrisons to check the water level of the dewatering well. When the water level drops to the design elevation, the power is turned off, and when the water level exceeds the design water level, the power is turned off again.... Repeatedly, until the whole project is dewatered The construction of the project is completed. During this process, a large number of personnel are required to inspect the site, resulting in a large waste of human resources. Contents of the invention [0003] The object of the present invention is to overcome the above defects and provide an automatic control method for the power supply of the dewatering well. [0004] An automatic control method for a ...
