Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit water level detection, and particularly relates to a foundation pit water level detector. Background Technique

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. Before excavation, the excavation plan should be determined based on geological and hydrological data, combined with the situation of nearby buildings on the site, and waterproof and drainage work should be done well. For those with shallow excavation, the method of sloping the side can be used to make the soil slope stable, and the slope size is determined according to relevant construction regulations. For those with deeper excavation and adjacent buildings, methods such as foundation pit wall support, shotcrete retaining wall method, and even methods such as diaphragm wall and column - type bored cast - in - place pile interlocking can be used in large - scale foundation pits to prevent the outer layer of soil from collapsing; for those with no impact on nearby buildings, the well point method can be used to lower the groundwater level and open - cut excavation with slopes can be adopted; in cold regions, the method of natural cold air freezing can be used for excavation, etc.

[0003] According to the "CN212658302U" in the Chinese utility model disclosure specification, it is recorded that "for the water level detector of the present utility model, the measuring head on the water level detector main body can penetrate into the test hole to detect the water level and is simultaneously pulled by a tape measure. When the water level detector contacts the water in the test hole, it can drive the locking mechanism to lock the reel and stop rotating. At this time, the depth of the water level in the test hole can be calculated by reading the scale of the tape measure. Among them, the guiding member has a guiding effect to prevent the measuring head from swinging and reduce its swing. Specifically, the driving motor can drive the crank to rotate, and through the transmission of the connecting rod, drive the pressing member to move. Since the pressing member is guided by the guide rail, its moving direction is vertical lifting. When the pressing member is pressed against the locking part, the locking part and the pressing member are relatively stationary, thus stopping the rotation of the reel to achieve the positioning function".

[0004] According to the above - mentioned patent, it can be known that, however, the existing water level detectors usually do not have a locking function. When the measuring head contacts the water surface, at least one person needs to hold the reel tightly to prevent the measuring head from further descending, and at least one person needs to observe the scale of the steel tape. However, when the detector is lowered, the rope will shake, resulting in the detector colliding with the inner wall of the foundation pit, damaging the detector and affecting the service life of the detector.
