DETAILED DESCRIPTION

[0023] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, a detachable surface settlement monitoring device comprises:

[0025] The support rod 1 is implanted in the road opening, and the upper end thereof is connected with a monitoring dome assembly 2 for monitoring land subsidence, and also includes a protective shell 3 for wrapping and protecting the entire monitoring dome assembly 2, and the protective shell 3 includes:

[0026] A base 31 is placed in a groove on the road surface, and a rod hole 311 is provided on the base 31 for the support rod 1 to pass through;

[0027] The protective cover 32 is connected to the base 31 , and a cavity for accommodating the monitoring dome assembly 2 is formed between the protective cover 32 and the base 31 .

[0028] The monitoring dome assembly 2 is provided with an internal thread connection shaft section 21 , and the monitoring dome assembly 2 is connected to the external thread connection section 11 at the upper end of the support rod 1 via the internal thread connection shaft section 21 .

[0029] When the settlement monitoring device is installed, since the support rod 1 is directly inserted into the ground, a monitoring dome assembly 2 is left at the top thereof, and the protection cover 32 is used to protect the dome assembly 2 from the outside.

[0030] A connecting portion 22 is provided on the outer wall of the internal thread connecting shaft section 21 , and the connecting portion 22 is used for cooperation with an external disassembly tool.

[0031] The connecting portion 22 is provided with a hexagonal hole 221 for cooperation with a hexagonal wrench. When the settlement monitoring device is not needed, the entire device can be removed from the support rod 1 by cooperating with the hexagonal hole 221 through the hexagonal wrench, and can be reused.

[0032] It also includes a spring 4, which is coaxially sleeved on the outside of the internal threaded connection section. One end of the spring 4 is fixedly connected to the connection part 22, and the other end is fixedly connected to the base 31. After the entire settlement monitoring device is installed, since the entire top protective cover 32 is slightly higher than the ground, when a vehicle passes by, it will roll over the protective cover 32. In order to prevent the internal support rod 1 from moving downward under force, thereby affecting the monitoring accuracy, the protective cover 32 is buffered by the spring 4, so that when the protective cover 32 receives pressure, the downward pressure can be reduced by the spring 4.

[0033] The protective cover 32 is provided with an upper flip cover 321 capable of opening the cavity. When the sedimentation monitoring device is not in use, the protective cover 32 can be sealed by the upper flip cover 321 on the protective cover 32 to prevent foreign matter from falling into the interior and affecting the monitoring accuracy.

[0034] A buffer member 312 is disposed at the upper edge of the opening of the base 31 , and the buffer member 312 is a rubber ring, which is used to buffer the impact pressure on the top of the protective cover 32 .

[0035] Working process:

[0036] Locate the monitoring point: Use conventional staking methods to determine the point location, and implant support rods 1 after opening the road;

[0037] Device connection: After assembling and connecting the base 31, the monitoring dome assembly 2 and the spring 4, use an Allen wrench to adjust the connection between the support rod 1 and the internal threaded connecting shaft section 21;

[0038] After the rubber ring is installed, the protective cover 32 and the base 31 are fixed through the upper and lower slots.

[0039] When measuring, the upper flip cover 321 is opened, and the level rod is placed horizontally on the top of the monitoring dome assembly 2 ; after finishing the measuring work, the operator closes the upper flip cover 321 .

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
