Description

Technical Field

[0001] The utility model belongs to the technical field of settlement observation, and in particular relates to a settlement observation device. Background Art

[0002] Under the load of the building, the foundation soil is compressed and causes vertical deformation or sinking. Uniform settlement generally does little harm to the building, but when it is too large, it will also reduce the elevation of the building and affect its use; uneven settlement is more harmful to the building, causing additional stress in the building and causing cracks, or even partial component fractures, endangering the safety of the building. When designing the foundation, the settlement should be estimated, so a device that can accurately measure the settlement is needed.

[0003] The patent document with announcement number CN203949661U discloses a settlement observation device, including: a settlement observation plate, including an observation plate, an observation tube vertically supported on the observation plate, and an outer sleeve sleeved on the observation tube; a limit structure, including a limit part movably sleeved on the outer sleeve and a support frame connected to the limit part. The settlement observation device of the utility model is provided with a support frame on the peripheral side of the settlement observation plate, so that the settlement observation plate always moves in the vertical direction. However, if the device is set at a position close to the construction building, the single support mode of the support frame is easily affected by the construction vibration, thereby affecting the measurement results.

[0004] The patent document with the announcement number CN217358491U discloses a new type of settlement observation plate settlement observation nail, including a wall, an observation plate is detachably fixedly provided on one side of the wall, a plug-in slot is provided on one side of the observation plate, an L-shaped observation nail is movably connected in the plug-in slot, and the top and bottom of the L-shaped observation nail are fixedly provided with limit plates, and limit slots are provided on the top inner wall and the bottom inner wall of the plug-in slot, and two limit plates are respectively slidably sleeved in the corresponding limit slots. The utility model can quickly fix the L-shaped observation nail on the observation plate in a plug-in manner to avoid the phenomenon of slipping or screwing too loose or too tight, which leads to inaccurate measurement results. At the same time, disassembly and recycling are relatively convenient and quick. Through the cooperation of the cross plate, reinforcement hole and fixing bolt, the L-shaped observation nail can be reinforced again to avoid tilting and affecting subsequent observations. However, the utility model is suitable for being set on the main body of the building. If it is to be set on the ground alone for measurement, it is necessary to set up a fixed platform separately, and the use conditions are subject to certain restrictions. Utility Model Content
