Automatic water level monitoring device in foundation pit water level observation well

Abstract

The invention discloses an automatic water level monitoring device in a foundation pit water level observation well. The automatic water level monitoring device comprises a floater, a plumb and a measuring line with length identification. The plumb is tied on the floater, the floater is tied at one end of the measuring line and then placed in the foundation pit water level observation well, the automatic water level monitoring device further comprises an elastic stretching unit, an automatic recorder and a data processor, the other end of the measuring line passes between an upper meshing wheel and a lower meshing wheel in the automatic recorder and is connected with the elastic stretching unit which can be stretched by sensing tension on the measuring line, and water level altitude data can be obtained by the data processor according to received moving variation values of the measuring line recorded by the automatic recorder. The automatic water level monitoring device greatly reduces work load of manual measuring, can achieve automatic, real-time and continuous monitoring, improves accuracy of monitoring and improves working efficiency.

Description

technical field [0001] The invention belongs to the technical field of water level measuring equipment, and in particular relates to an automatic water level monitoring device in a foundation pit water level observation well. [0002] Background technique [0003] When carrying out foundation pit dewatering construction in urban buildings, in order to ensure the safety of existing buildings and underground pipelines and other facilities outside the foundation pit, it must be ensured that the groundwater level drop outside the foundation pit does not exceed the allowable safety range. Therefore, several groundwater level observation wells are often arranged outside the foundation pit and near existing buildings to observe the groundwater level. Once the groundwater level drops below the safety line, immediately stop the foundation pit precipitation or carry out groundwater recharge treatment outside the foundation pit to ensure the safety of existing buildings. [0004] In ...
