Abstract
Description
Technical Field
[0001] The utility model provides a ground subsidence monitoring device, belonging to the technical field of ground subsidence monitoring. Background Art
[0002] Subsidence, also known as ground subsidence or land subsidence, can occur quickly or slowly. It can be caused by natural factors, such as the compaction of natural sediments, or by human activities, such as the excessive exploitation of groundwater, oil, and natural gas. Subsidence caused by human activities is becoming more and more common. When encountering soft strata during subway or building construction, it is necessary to monitor ground subsidence when working on soft strata to facilitate changing construction methods according to actual geological conditions. When monitoring ground subsidence, it is essential to use a ground subsidence monitoring device.
[0003] When conducting inspections, the ground subsidence monitoring device buries the bedrock benchmark at an appropriate depth in the ground, exposes the level head and observation plate, and drops the observation plate onto the ground. When the ground settles, the observation plate sinks with the ground, causing the bedrock benchmark to rise and extend. Then, by carrying the measuring tool to the appropriate location to measure the relative height between the level head and the reference object, the ground subsidence can be observed.
[0004] The above-mentioned existing ground subsidence monitoring devices can basically meet the needs of use. However, when monitoring and measuring ground subsidence, the measuring tool is often carried to the appropriate location and then the relative height between the level head and the reference object is measured. This is relatively time-consuming and labor-intensive, and the fatigue level of the workers is relatively high. In addition, the lack of protective components makes the bedrock benchmark directly exposed to the external environment vulnerable to rain erosion and collisions with foreign objects such as flying sand and gravel, which in turn causes the bedrock benchmark to be affected by external factors and affect the ground subsidence monitoring effect. Based on this, the utility model provides a ground subsidence monitoring device. Utility Model Content
[0005] The technical problem solved by the utility model is that monitoring and measuring ground subsidence is relatively time-consuming and labor-intensive, and the fatigue intensity of workers is relatively high; the bedrock benchmarks exposed to the external environment are easily eroded by rainwater and collided with foreign objects, which in turn causes the bedrock benchmarks to be affected by external factors and the ground subsidence monitoring effect.
[0006] In order to solve the technical problem, the technical solution provided by the utility model is: a ground subsidence monitoring device, including an observation plate, a bedrock benchmark passed through the center of the observation plate, a scale rod placed on the outside of the bedrock benchmark on the top of the observation plate, a positioning sleeve on the scale rod, a locking bolt provided on one side wall of the positioning sleeve, a hollow rod provided on the other side wall of the positioning sleeve, a slide plate slidably connected inside the hollow rod, and a connecting rod passing through the hollow rod and placed above the bedrock benchmark on the side wall of the slide plate; an annular groove is provided on the top of the observation plate to the outside of the scale rod, and a protective cover is provided in the annular groove and placed on the outside of the bedrock benchmark and the scale rod.
[0007] Furthermore, a plurality of limiting protrusions are provided on the circumference of the inner side wall of the annular groove, and a plurality of limiting grooves matching the limiting protrusions are provided on the circumference of the bottom of the protective cover.
[0008] Furthermore, a through hole for a bedrock pole to pass through is provided at the center of the observation plate, a level head is provided at the top of the bedrock pole, and a cone is provided at the bottom of the bedrock pole.

[0010] Furthermore, a threaded hole matching the locking bolt is provided on one side wall of the positioning sleeve, and the screw end of the locking bolt penetrates into the positioning sleeve and is tightly attached to the side wall of the scale rod.
[0011] Furthermore, a blunt-round limit stopper is provided at the end of the connecting rod, and a slide rail that matches the side wall of the slide plate is symmetrically provided on the inner side wall of the hollow rod.
[0012] Beneficial effects of the utility model:
[0013] 1. It can facilitate workers to monitor ground subsidence conveniently and at any time. There is no need to carry measuring tools to the appropriate location to measure the relative height between the level head and the reference object, which saves time and effort and reduces the fatigue intensity of workers;

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] According to the attached Figure 1 As shown: The utility model provides a ground subsidence monitoring device: it includes an observation plate 2, a bedrock benchmark 1 is passed through the center of the observation plate 2, a through hole 13 for the bedrock benchmark 1 to pass through is provided in the center of the observation plate 2, a level head 14 is provided on the top of the bedrock benchmark 1, and a cone 15 is provided at the bottom of the bedrock benchmark 1. The bedrock benchmark 1 can be conveniently buried at a suitable depth in the ground through the cone 15, and the level head 14 and the observation plate 2 are exposed. The observation plate 2 falls on the ground. When the ground settles, the observation plate 2 settles with the ground, causing the bedrock benchmark 1 to rise and extend. By carrying a measuring tool to a suitable position to measure the relative height between the level head 14 and the reference object, the ground subsidence can be observed.
[0022] According to the attached Figure 1 、 34: The top of the observation plate 2 is provided with a scale rod 3 placed on the outside of the bedrock benchmark 1, and the scale rod 3 is provided with scale lines 16. A positioning sleeve 4 is sleeved on the scale rod 3, and a locking bolt 5 is provided on one side wall of the positioning sleeve 4. A threaded hole matching the locking bolt 5 is provided on one side wall of the positioning sleeve 4. The screw end of the locking bolt 5 penetrates into the positioning sleeve 4 and fits tightly against the side wall of the scale rod 3 so as to lock the positioning sleeve 4 in a suitable position. A hollow rod 6 is provided on the other side wall of the positioning sleeve 4, and a slide plate 7 is slidably connected in the hollow rod 6. The side wall of the slide plate 7 is provided with a connecting rod 8 that passes through the hollow rod 6 and is placed above the bedrock benchmark 1. The end of the connecting rod 8 is provided with a blunt-round limit stop head 17, and the inner wall of the hollow rod 6 is symmetrically provided with a slide rail 18 that matches the side wall of the slide plate 7, which plays a role in limiting the slide plate 7. By moving the positioning sleeve 4 to a suitable height, the hollow rod 6 and the connecting rod 8 are driven to move to a suitable height, and the connecting rod 8 is pulled out from the hollow rod 6, so that the top of the level head 14 fits with the top of the connecting rod 8. The positioning sleeve 4 is locked in the appropriate position by turning the locking bolt 5, which makes it convenient for the staff to monitor the ground subsidence at any time, saves time and effort, and reduces the fatigue intensity of the staff monitoring.

The inner wall circumference of the annular groove 9 is provided with multiple limiting protrusions 11, and the bottom circumference of the protective cover 10 is provided with multiple limiting grooves 12 matching the limiting protrusions 11. By limiting the protective cover 10 in the annular groove 9, the bedrock benchmark 1 and the scale rod 3 inside the protective cover 10 can be protected, effectively preventing the bedrock benchmark 1 and the scale rod 3 from being directly exposed to the external environment and eroded by rainwater, avoiding collision with foreign objects such as flying sand and gravel, so as to prevent external factors from affecting the ground subsidence monitoring effect.
[0024] Principle of the utility model
[0025] The bedrock benchmark 1 can be conveniently buried at a suitable depth in the ground by inserting the cone 15, exposing the level head 14 and the observation plate 2, and the observation plate 2 falls on the ground. When the ground settles, the observation plate 2 settles with the ground, causing the bedrock benchmark 1 to rise and extend. By moving the positioning sleeve 4 to a suitable height, the hollow rod 6 and the connecting rod 8 are driven to move to a suitable height, and the connecting rod 8 is pulled out from the hollow rod 6, so that the top of the level head 14 fits with the top of the connecting rod 8. The positioning sleeve 4 is locked in a suitable position by turning the locking bolt 5, so that the staff can conveniently monitor the ground settlement at any time. There is no need to carry measuring tools to the appropriate position to measure the relative height between the level head 14 and the reference object, which saves time and effort and reduces the fatigue intensity of the staff monitoring.
[0026] By limiting the protective cover 10 in the annular groove 9, the bedrock benchmark 1 and the scale rod 3 inside the protective cover 10 can be protected, effectively preventing the bedrock benchmark 1 and the scale rod 3 from being directly exposed to the external environment and eroded by rainwater, and avoiding collisions with foreign objects such as flying sand and gravel, so as to prevent external factors from affecting the ground subsidence monitoring effect.
