[0001] The present invention relates to the technical field of engineering measurement, and in particular to an inclinometer suitable for monitoring deep horizontal displacement and a use method thereof. Background Art

[0002] The inclinometer for deep horizontal displacement monitoring is mainly used to measure the top angle and azimuth of engineering structures such as boreholes, foundation pits, foundations, walls, dam slopes, etc. at different depths, as well as to monitor the deep horizontal displacement of underground rock and soil, bridge deflection, and the movement of potential sliding surfaces of unstable slopes. Deep horizontal displacement monitoring is of great significance for ensuring the safety of people’s lives and property and the long-term stable operation of projects.

[0003] The patent document with announcement number CN220150404U discloses a protective device for an inclinometer tube for monitoring deep horizontal displacement of a pile, including an inclinometer tube, which is installed in a reinforcement cage of the pile. The portion of the inclinometer tube located at the top of the pile is wrapped with a geotextile layer, and the geotextile layer is covered with a protective tube. The protective device for the inclinometer tube for monitoring deep horizontal displacement of the pile also includes a hook. The hook is in an "S" shape, one end of the hook is hooked on the main reinforcement of the reinforcement cage of the pile, and the other end is hooked on the protective tube. The protective tube is fixed to the main reinforcement of the reinforcement cage of the pile through a number of hooks arranged at intervals above and below.

[0004] However, the above invention has the following shortcomings: the inclinometer tube can detect the deep horizontal displacement, but the inclinometer tube is only fixed and installed by hooking reinforcement, which not only has poor installation stability, but also has poor protection effect on the inclinometer tube in the later construction, which is easy to affect the normal use of the inclinometer device, so there are certain limitations. Summary of the invention

Through this device, the installation of the inclinometer device can be well realized, and it is not easy to be damaged during concrete pouring and subsequent pile breaking. After the equipment is installed, it has a good protective effect on the equipment, has stability, and the monitoring results are highly accurate. The data has better reference value and can better reflect the safety status of the foundation pit.
