Protection device for building foundation pit displacement monitoring and supporting based on capacitance change

Abstract

The invention discloses a capacitance change-based protection device for building foundation pit displacement monitoring support, which comprises a protection cylinder, a monitoring box body is slidably mounted on the side surface of one end of the protection cylinder, a monitoring rod is slidably mounted on the surface of one end of the monitoring box body, and a puller spring slidably sleeves the surface of one end of the monitoring rod. A top plate is fixedly connected to the surface of the other end of the monitoring rod, auxiliary rods are fixedly connected to the two ends of the surface of the periphery of the monitoring box body, guide wheels are rotationally installed on the surfaces of one ends of the auxiliary rods, a connecting ring is fixedly connected to the surface of the other end of the protective cylinder, and a T-shaped ring groove is formed in the surface of the connecting ring. And a T-shaped block is slidably installed on the side face of the T-shaped ring groove, a locking threaded rod is fixedly connected to the surface of one side of the T-shaped block, and a positioning block is fixedly connected to the surface of the other end of the locking threaded rod, so that the use convenience and stability can be greatly improved, and the comprehensiveness and accuracy of installation and protection are guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, and more specifically relates to a protection device for monitoring and supporting building foundation pit displacement based on capacitance changes. Background technique [0002] In the foundation pit excavated during the construction process, in order to ensure the follow-up construction, it is necessary to use a displacement monitoring device to monitor the foundation pit. Most of the commonly used monitoring devices are based on capacitance changes, which can be monitored and displayed by changing the capacitance through distance changes. In order to avoid interference from external factors, it is necessary to use protective devices to protect the monitoring equipment. [0003] However, most of the existing foundation pit monitoring equipment protection devices are simple fixed base structures, which are directly connected to the bottom of the monitoring equipment to assist positioning, w...

Problems solved by technology

[0003] However, most of the existing foundation pit monitoring equipment protection devices are simple fixed base structures, which are directly connected to the bottom of the monitoring equipment to assist positioning, which not only cannot provide comprehensive protection, but also easily causes displacement monitoring errors due to equipment movement. angle, and can only be positioned in one direction, and cannot be adjusted according to the shape of the foundation pit. The positioning stability is insufficient, the practicability is poor, and there is no protection for the monitoring connection position, which is not conducive to adjustment and use, and needs to be improved.
