Description

Technical Field

[0001] The utility model belongs to the technical field of ground subsidence observation, and particularly relates to a ground subsidence observation device. Background Art

[0002] Ground subsidence is also called ground subsidence or ground subsidence, which specifically refers to a phenomenon of ground subsidence. It is currently a major engineering geological problem in major cities around the world. It generally manifests itself in two forms: regional subsidence and local subsidence. It can cause buildings to tilt and destroy the stability of the foundation. Coastal cities will cause seawater to flow back, which has a great impact on production and life. There are many reasons for ground subsidence. Crustal movement, sea level rise, etc. can cause regional subsidence; and the main cause of local ground subsidence in cities is closely related to the large-scale exploitation of groundwater. At present, the observation and detection method of building settlement is mainly to install ground settlement observation marks at the four corners of the building. In the ground settlement observation, the level can be used to observe the changes in the settlement observation mark, thereby measuring the settlement of the ground or building. By comparing the elevation values ​​of the same point at different times, the settlement can be calculated, and then the stability of the foundation and the safety of the building can be evaluated.

[0003] A Chinese patent with publication number CN216344811U discloses a level that is easy to install and disassemble, including a level and a bracket, the bottom of the level is fixedly connected to a connecting seat, the bottom surface of the connecting seat is provided with a socket, the inner wall of the socket is provided with an annular groove, the bracket includes a mounting seat, the bottom of the mounting seat is hinged with no less than three supporting tubes, the top of the mounting seat is integrally formed with a cylindrical boss, the socket is adapted to the cylindrical boss, and the inner wall of the mounting seat is rotatably connected with a bidirectional screw.

[0004] The ground subsidence observation level in the above-mentioned prior art still has certain shortcomings during actual use.
