Description

Technical Field

[0001] The utility model belongs to the field of foundation settlement monitoring devices, in particular to a monitoring device for measuring the settlement of land foundations constructed by sea reclamation. Background Art

[0002] Foundation settlement refers to the sinking of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt and crack, making it impossible to use normally, and increase the safety hazard of the building. In order to prevent hidden dangers such as tilting of the building, the sinking position of the foundation surface is generally monitored to determine whether to carry out settlement reinforcement to eliminate the safety hazard. At present, the foundation settlement monitoring device is generally composed of a rack, a terminal, a laser transmitter and a light sensor. When in use, the rack is first placed at the foundation settlement position, and the laser transmitter installed at the top of the rack is started, so that the laser transmitter generates laser and irradiates the foundation settlement surface. The foundation surface will reflect the laser, and the light sensor located at the top of the rack will respond to the reflected laser. The laser is used to capture and collect data, and the collected information is transmitted to a terminal installed at the top of the rack. The terminal then compares and analyzes the collected information with the benchmark data to calculate the depth of foundation settlement. However, factors such as foundation settlement may easily cause the ground on which the rack is placed to be uneven. The rack is generally placed in the form of multiple supporting legs, and the specifications of the multiple supporting legs are the same. When in use, the insertion parts on the multiple supporting legs are first inserted into the ground. At this time, the supporting parts of the supporting legs are attached to the ground. If the ground is uneven, the ground placement points of the multiple supporting legs are at different heights, which will cause a high probability of the rack tilting, thereby causing the probe part composed of a laser emitter and a light sensor located at the top of the rack to tilt, thereby affecting the inaccurate monitoring data.

[0003] The Chinese patent application number CN202221582611.8 discloses a foundation settlement monitoring device, including a settlement monitoring body and two parallel inverted T-shaped rods, the upper side of the vertical parts of the two inverted T-shaped rods is rotatably connected to a horizontally arranged rotating shaft, the outer end of the rotating shaft is fixed with a U-shaped frame, the bottom end of the U-shaped frame is provided with a settlement monitoring body and the settlement monitoring body is located at the lower side of the rotating shaft, the two probes of the settlement monitoring body extend out of the lower side of the U-shaped frame, the middle position of the lower end of the U-shaped frame is fixedly connected to a load-bearing outer cylinder and the load-bearing outer cylinder is fixedly connected to the load-bearing outer cylinder. The cylinder is located on the inner side of the two probes. This design will cause the load-bearing outer cylinder, the U-shaped frame and the settlement monitoring body to rotate around the rotating axis under the action of the weight of the load-bearing outer cylinder itself, so that the settlement monitoring body is rotated to a vertical state with the ground, so as to achieve the purpose of making the probe of the settlement monitoring body always vertical to the ground, which is easy to use, improves the monitoring quality, and effectively improves the practicality. The foundation settlement monitoring device in this application has an inverted T-bar setting, so that the height of the foundation settlement monitoring device is higher when the foundation settlement monitoring device is placed flat, which increases the occupied volume of the device.

[0004] In view of this, the present utility model is proposed. Utility Model Content
