Description

Technical Field

[0001] The utility model relates to the technical field of ground building coordinates, in particular to a protection device for ground building coordinates. Background Art

[0002] Settlement observation is a basic work in deformation observation of construction projects. With the vigorous development of my country's construction industry and transportation construction, settlement observation is becoming more and more important, especially in underground engineering and foundation engineering construction. Due to the increase of overlying load on the soil or the drop of groundwater level, the soil will produce a certain amount of settlement. In order to ensure the safety of buildings and personnel and minimize the impact of engineering construction on the geological environment, we need to conduct stratified settlement monitoring of the soil in a specific area. At the same time, we can also accumulate actual settlement data into the database for reference in subsequent engineering construction and scientific research institutes.

[0003] In the publication number 202020103977.7, the utility model discloses a downhole measurement control point protection device, including a main body, mounting holes are arranged around the top of the main body, fixing bolts are arranged inside the mounting holes, the main body is fixedly connected to the base by fixing bolts, a measuring nail is arranged in the middle of the base, the middle part of the main body is hollow, a top cover is sleeved in the middle part of the main body, the top cover and the main body are gap-matched, the top cover is located above the measuring nail, a handle is fixedly connected to the top of the top cover, a sealing gasket is arranged at the connection between the top cover and the main body, and the material of the sealing gasket is rubber. The utility model relates to the field of control and measurement technology. This underground measurement control point protection device has achieved the purpose of transforming the main body, adopting a solid main body, installed on the top of the base, and the top cover is installed with the main body, and a fixing device is set to facilitate the quick disassembly and installation of the top cover, thereby improving the service life and meeting the use requirements. However, the above-mentioned device structure is relatively simple, and the pressure may cause the device to be unable to be adjusted when a vehicle passes, resulting in deformation of the device, and the height of the device cannot be adjusted according to the height of the observation nail when in use. For this reason, we propose a more widely applicable protection device for ground building coordinates. Summary of the invention

[0004] The utility model aims to solve the deficiencies of the prior art and provides a protection device for ground building coordinates.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A protective device for ground building coordinates comprises an observation nail, a fixing frame is arranged outside the observation nail, two groups of opposite protective shells are arranged on the fixing frame, two groups of supporting components are arranged on the left and right sides of the fixing frame below the protective shells, positioning pieces are arranged on the left and right sides of the fixing frame, and positioning bolts are inserted at both ends of the positioning piece through a threaded structure.

[0007] A gasket is arranged at the bottom of the fixing frame.

[0008] The bottom ends of the two groups of protective shells are hinged to the fixed frame through hinges.

[0009] The outer side surface of the middle and lower part of the protective shell is three slope surfaces.

[0010] A handle groove is provided on the top of the protective shell.

[0019] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] like Figure 1-Figure 4 As shown, a protective device for ground building coordinates includes an observation nail 1, a fixed frame 2 is arranged outside the observation nail 1, two groups of opposite protective shells 6 are arranged on the fixed frame 2, two groups of supporting components are arranged on the left and right sides of the fixed frame 2 below the protective shells 6, positioning pieces 3 are arranged on the left and right sides of the fixed frame 2, and positioning bolts 4 are inserted at both ends of the positioning piece 3 through a threaded structure. The design of the positioning piece 3 and the positioning bolt 4 helps to firmly fix the positioning device at a predetermined position to prevent it from moving during the observation process, thereby ensuring the accuracy of the observation result.

[0022] A gasket 5 is provided at the bottom of the fixed frame 2, which can increase the contact area with the ground and reduce the impact of uneven ground on observation accuracy. At the same time, it provides buffering and reduces the interference of vibration on observation. It is also convenient to increase the height of the device by adding the number of gaskets 5 according to the height of the observation nail 1 when in use.

[0023] The bottom ends of the two groups of protective shells 6 are hinged to the fixed frame 2 through hinges 7, and can be easily opened and closed to protect the internal observation nails 1 from bad weather or external impacts.

[0024] The outer side surface of the middle and lower part of the protective shell 6 is three slopes, and the slope structure can facilitate the passage of vehicles.

[0025] A handle groove 8 is provided on the top of the protective shell 6. The design of the handle groove 8 enables an operator to open or close the protective shell 6 more easily, thereby improving the convenience of operation.

[0026] The contacting side of the two groups of protective shells 6 and the contacting side of the fixing frame 2 are both provided with rubber pads 9, which provide additional sealing and buffering. The rubber pads 9 can also allow the protective shells 6 to have a certain angle change space when a vehicle passes.

[0027] The support assembly includes a support frame 10, an adjusting rod 11 is movably inserted at the upper end of the support frame 10, a limiting ring 13 is arranged on the outer periphery of the lower end of the adjusting rod 11, and a supporting spring 12 is arranged inside the support frame 10. When the protective shell 6 descends, the protective shell 6 can be supported by the adjusting rod 11 and the supporting spring 12 at the upper end of the support frame 10, so that the protective shell 6 can be quickly reset after deformation, and the limiting ring at the lower end of the adjusting rod 11 can prevent the support frame 10 from being separated from the position of the adjusting rod 11.

[0028] Working principle: When in use, the fixing frame 2 is sleeved on the outside of the observation nail 1, and a suitable number of washers 5 are added to the lower side of the fixing frame 2 according to the height of the observation nail 1. Then, the positioning device is firmly fixed in a predetermined position through the design of the positioning piece 3 and the positioning bolt 4 to prevent it from moving during the observation process, thereby ensuring the accuracy of the observation result. When observation is required, the design of the handle groove 8 allows the operator to more easily open or close the protective shell 6 hinged to the fixing frame 2 through the hinge 7, thereby improving the convenience of operation. When a vehicle passes, the protective shell 6 is subjected to a decrease in pressure, and the protective shell 6 is supported by the adjusting rod 11 and the supporting spring 12 at the upper end of the support frame 10, so that the protective shell 6 can be quickly reset after deformation, and the limiting ring 13 at the lower end of the adjusting rod 11 can prevent the support frame 10 from being separated from the position of the adjusting rod 11.
