Abstract

The invention discloses a civil engineering deep foundation pit inclinometer base tube. The civil engineering deep foundation pit inclinometer base tube comprises a tube body, wherein an inclinometer is arranged in the tube body, the top of the tube body is fixedly connected with a cover plate, a threading pipe is arranged at an upper end of the cover plate, the threading pipe is communicated with the tube body, a clamping device is arranged at the bottom of the tube body, the clamping device comprises a bottom plate and a water-soluble paper adhesive tape, the bottom plate is fixed to a lower end of the tube body, the lower side of the bottom plate is fixedly connected with a plurality of fixing shafts which are evenly and annularly arranged with the axis of the bottom plate as the center, and outer sides of the fixing shafts are rotationally connected with a rotating plate. The civil engineering deep foundation pit inclinometer base tube is advantaged in that after the water-soluble paper adhesive tape is broken when encountering water, a tip of the rotating plate is in contact with a hole wall, and the pipe body is controlled to rotate reversely through the cover plate, so the tip of the rotating plate is inserted into the hole wall, the pipe body is firmly mounted, the inclinometer does not move during use, and detection accuracy is high.

Description

technical field [0001] The invention relates to the technical field of foundation inclinometers, in particular to a base pipe for inclinometer pipes for deep foundation pits in civil engineering. Background technique [0002] With the rapid development of municipal infrastructure in major cities in China, it has become a common phenomenon to construct subways and high-rise buildings near existing buildings. In the prevention of geological landslides, construction monitoring, dams and other scenarios, the sliding inclinometer application is used to monitor the deep displacement and deformation under the surface, and it is a very widely used subsurface displacement and deformation measurement equipment. . Therefore, during the construction process, the sliding inclinometer is used to monitor the deep horizontal displacement to monitor the deformation of the building during the construction process. However, after the inclinometer in the prior art is installed in the inclinom...
