[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 2 As shown, a monitoring point protection device for foundation pit monitoring includes: a chassis 1 fixed to the ground, with the monitoring point located in the middle of the chassis 1; a protective cover 2 detachably connected to the chassis 1; an opening and closing door 3 on the protective cover 2; an anti-pressure mechanism 4 located around the protective cover 2; and a flag insertion mechanism 5 detachably connected to the protective cover 2.

[0024] The base 1 is a cuboid with an opening in the center. The monitoring point is located in the center of the opening. Expansion bolts 11 are located at the four corners of the base 1, and the expansion bolts 11 are driven into the ground, which is a hardened concrete surface. During installation, the base 1 is fixed to the expansion bolts 11, thus fixing its position. After fixing the base 1, it will not move during routine construction by machinery and workers, thereby allowing the device to remain in a fixed position around the monitoring point. After the monitoring point fails, the upper part of the expansion bolts 11 can be cut off, and the base can be removed and reused for the next monitoring point.

[0025] The chassis 1 has a connecting plate 12 at one end, and a connecting groove 13 on the outer side of the connecting plate 12. The connecting groove 13 is used to fix the position of the protective cover 2. The two side walls of the protective cover 2 are inserted into the two connecting grooves 13 respectively, so that the protective cover 2 can be quickly installed on the base, accurately positioned, and easy to fix in the next step. After the protective cover 2 is installed, the bottom surface of the side wall of the protective cover 2 inserted into the connecting groove 13 contacts the top surface of the chassis 1, and the bottom surface of the side wall of the protective cover 2 not inserted into the connecting groove 13 contacts the ground.

[0026] The top surface of the protective cover 2 is located above the connecting plate 12. The connecting plate 12 is provided with a threaded hole, and the protective cover 2 is provided with a round hole of the same diameter as the threaded hole. After the protective cover 2 is installed, the threaded hole and the round hole are in the same straight line.

[0027] A positioning bolt 21 runs through the protective cover 2. The bottom of the positioning bolt 21 is screwed to the connecting plate 12. By turning the positioning bolt 21, the bottom of the positioning bolt 21 enters the threaded hole, thereby connecting the protective cover 2 and the chassis 1. The protective cover 2 covers the upper part of the monitoring point to prevent the monitoring point from being damaged, and at the same time prevents a large amount of rainwater and dust from eroding the monitoring point. When the monitoring point needs to be used, the positioning bolt 21 can be removed and the protective cover 2 can be removed to expose the monitoring point.

[0028] The chassis 1 is also provided with a partition plate 14, which is perpendicular to the side wall of the connecting plate 12. The partition plate 14 and the side wall of the connecting plate 12 surround the expansion bolt 11, making it easier to find the correct position so that the expansion bolt 11 can pass through the bolt when installing the chassis 1.

[0029] The opening and closing door 3 is located above the monitoring point. The opening and closing door 3 is connected to the protective cover 2 via a hinge. The front end of the opening and closing door 3 is equipped with a handle 31. The monitoring point can be exposed after the opening and closing door 3 is pulled up by the handle 31. If the support does not conflict with the protective cover 2 that opens and closes the opening and closing door 3 during the foundation pit measurement, the opening and closing door 3 can be opened directly and aligned with the monitoring point. This can save the time of opening the monitoring point and thus improve the efficiency of foundation pit monitoring.

[0030] The protective cover 2 has an upper limit groove 22, which can contact the bottom of the handle 31. The limit groove 22 restricts the opening and closing door 3 from rotating downward. When the handle 31 is in contact with the limit groove 22, the top surface of the opening and closing door 3 and the top surface of the protective cover 2 are on the same plane.

[0031] The anti-pressure mechanism 4 is used to protect the edges of the protective cover 2 and prevent the positioning bolts 21 from being deformed by mechanical pressure. The anti-pressure mechanism 4 is installed if the monitoring point is located on the roadway; otherwise, it is not necessary. The anti-pressure mechanism 4 includes a truncated cone cover 41 and a protective block 42. The sidewall of the truncated cone cover 41 is sloping, and the center of the truncated cone cover 41 has a hole larger than the size of the opening / closing door 3. The truncated cone cover 41 does not affect the opening and closing of the opening / closing door 3. The truncated cone cover 41 covers the sidewall of the protective cover 2. When construction machinery passes through, it transitions from the sloping sidewall of the truncated cone cover 41 to the top surface, reducing damage to the tires of the construction machinery compared to the right-angled sidewall of the protective cover 2. It also protects the protective cover 2 from damage and deformation, facilitating disassembly and assembly. The protective block 42 is located on the inner wall of the truncated cone cover 41, which is positioned above the positioning bolts 21. The protective block 42 protects the positioning bolts 21 from being crushed, ensuring smooth disassembly and assembly of the positioning bolts 21.

[0032] The flag-planting mechanism 5 includes a flag-planting hole 51 and a pin hole 52 on the protective cover 2. The flag-planting hole 51 and the pin hole 52 penetrate the protective cover 2 and do not contact the partition plate or the connecting plate 12. It also includes a flagpole 53, a positioning pin 54 and a connecting rod 55. The flagpole 53 is detachably connected to the flag-planting hole 51. The connecting rod 55 is slidably connected to the flagpole 53 and is perpendicular to the flagpole 53. The positioning pin 54 penetrates the connecting rod 55 and the pin hole 52 and is parallel to the flagpole 53. In use, the bottom of the positioning pin 54 and the flagpole 53 are in contact with the top surface of the chassis 1. The positioning pin 54 and the flagpole 53 are mutually supported by the positioning rod to prevent the flagpole 53 from tilting.

[0033] The flag insertion hole 51 and pin hole 52 are detachably connected to a sealing plug 6. When the monitoring point is located in a difficult-to-find location, the flagpole 53 is installed to facilitate quick discovery by monitoring personnel. When the monitoring point is located on a road, the flagpole 53 is removed and the sealing plug 6 is installed to seal the flag insertion hole 51 and pin hole 52 to prevent water and dust from passing through, and it does not affect traffic.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
