Description

Technical Field

[0001] The invention belongs to the technical field of engineering monitoring technology, and in particular relates to an installation and recovery method of a surface settlement monitoring point protection device. Background Art

[0002] Project monitoring is essential to ensuring safety and quality throughout the construction process. The accuracy and real-time nature of monitoring data provide the most effective basis for guiding on-site construction. Surface settlement monitoring, in particular, is crucial for the safety and control of underground spaces, urban rail transit, and slope (foundation pit) projects.

[0003] The number and layout of monitoring points should meet the specifications and design requirements. In particular, the number of monitoring points is generally large, which requires more monitoring personnel and material costs. According to statistics, the total investment in instruments and materials for a monitoring project can account for 20% to 40% of the entire monitoring cost. Therefore, faced with the increasingly difficult engineering construction environment, the recycling of instrument and material costs has become one of the key issues of concern to monitoring personnel, and the recycling of materials has always been one of the initiatives advocated by the country.

[0004] At present, the protective covers of settlement monitoring points are usually cylindrical devices made of iron and plastic materials. Each protective cover is expensive and is used in large quantities. In addition, for urban subway and deep foundation pit monitoring projects, if the monitoring points and protective covers are left untreated for a long time, they may be affected by the outside world and the climate and protrude from the surface, thereby posing safety hazards such as stumbling and punctures to residents and vehicles. In addition, the clean road surface becomes "riddled with holes" because of the monitoring points, which is very detrimental to the development of urban civilization construction.

[0005] Therefore, in response to the above series of problems, it is urgent to propose a recyclable installation and recycling method for a surface subsidence monitoring point protection device. Summary of the Invention

[0006] The present invention provides an installation and recycling method for a surface settlement monitoring point protection device in order to solve a series of major problems such as the inability to recycle existing settlement monitoring point protection covers, which wastes materials, increases monitoring costs, poses safety hazards such as tripping and punctures to urban residents and vehicles, and affects the development of urban civilization construction.

[0007] The present invention is achieved through the following technical solutions:

[0008] A method for installing and recovering a surface subsidence monitoring point protection device, the surface subsidence monitoring point protection device comprising a top cover, a main retaining wall, an adapter body, and a splicing block; the main retaining wall is a curved plate structure, provided with a first groove and a second groove on both sides thereof, and axial holes are respectively provided on both sides of the main retaining wall, and the top cover is hinged to the main retaining wall; the adapter body is a curved plate structure, provided with a third groove and an axial hole on one side of the adapter body, and a first mounting ring is provided on the other side of the adapter body; the splicing block is a curved plate structure, provided with a second mounting ring and a third mounting ring on both sides of the splicing block;

[0009] The installation and recovery method of the surface settlement monitoring point protection device is as follows:

[0010] Step 1: Use a water drill to drill a hole at the designed monitoring point and clean the bottom of the hole until it is flat to form an installation hole;

[0011] Step 2: Use an electric drill to drill a hole in the center of the installation hole, and then use an air drill to insert the steel bar vertically into the hole;

[0012] Step 3: Use the first latch to connect the first groove of the main guard wall and the third mounting ring of the splicing block, use the second latch to connect the second groove of the main guard wall and the first mounting ring of the adapter, and use the third latch to connect the third groove of the adapter and the second mounting ring of the splicing block, thereby enclosing and splicing the main guard wall, the adapter, and the splicing block into a cylinder.

[0013] Step 4: Place the cylinder into the installation hole in step 1, cover it with the top cover, and fill the gap between the installation hole and the cylinder with fine sand to fix it, thus completing the installation of the surface settlement monitoring point protection device;

[0014] Step 5: After the project monitoring period is over, use pliers to pull out the pin of the surface settlement monitoring point protection device, push the splicing block and the adapter inward, so that the surface settlement monitoring point protection device is disassembled and the diameter becomes smaller;

[0015] Step 6: After the surface settlement monitoring point protection device is decomposed and its diameter becomes smaller, it can be easily taken out of the installation hole, and then asphalt is backfilled in the installation hole until the surface is leveled, thereby completing the recovery of the surface settlement monitoring point protection device.

[0016] In the above technical solution, the surface settlement monitoring point protection device is made of iron or high-strength plastic.

[0017] In the above technical solution, the wall thickness of the main protective wall, the adapter body and the splicing block is 3mm-5mm, and the height is 50mm-100mm.

[0018] In the above technical solution, an axial welding strip is welded to the outer wall of the main protective wall, and the top cover is hinged to the top of the welding strip.

[0019] In the above technical solution, the top cover is circular, and its diameter is equal to the diameter of the cylinder enclosed by the main protective wall, the adapter and the splicing block, so that the top cover can cover the opening of the cylinder.

[0020] In the above technical solution, the diameter of the cylinder formed by the main protective wall, the adapter body and the splicing block is slightly smaller than the diameter of the mounting hole so that it can be placed in the mounting hole.

[0021] The advantages and beneficial effects of the present invention are:

[0022] The present invention is an assembled structure, each component can be recycled, and the size fit and cooperative work between the main protective wall, the transition body and the splicing block can ensure the normal use and recycling of the entire protective device.

[0023] The present invention has a simple structure and low production cost, can meet the market demand for mass production, and solves the problem that traditional monitoring point protective covers cannot be recycled, effectively reduces the investment in monitoring costs, and avoids material waste.

[0024] The application of this invention solves a series of major problems such as the safety hazards of tripping and tire punctures to urban residents and vehicles caused by the failure to recycle the protective covers of traditional monitoring points in a timely manner, and affects the development of urban civilization construction.

[0031] The wall thickness of the main guard wall 2, the adapter body 3 and the splicing block 4 is 3mm-5mm, and the height is 50mm-100mm. The main guard wall 2, the adapter body 3 and the splicing block 4 can form a cylinder a, and the diameter of the cylinder is slightly smaller than the diameter of the mounting hole (usually 135mm-155mm) so that it can be placed in the mounting hole.

[0032] Specifically, the main guard wall 2 is an arc-shaped plate structure with a base at its bottom end. A first groove 2-2 and a second groove 2-3 are provided on either side of the main guard wall 2. Axial holes are provided at both ends of the main guard wall 2 corresponding to the first groove 2-2 and the second groove 2-3. An axial welding strip 2-1 is welded to the outer wall of the main guard wall 2. The top cover 1 is hinged on the top of the welding strip 2-1. The diameter of the top cover 1 is equal to the diameter of the cylinder enclosed by the main guard wall 2, the adapter body 3, and the splicing block 4, so that the top cover 1 can cover the opening of the cylinder. The adapter body 3 is an arc-shaped plate structure with a base at its bottom end. A third groove 3-1 is provided on one side of the adapter body 3. An axial hole is provided on the side corresponding to the position of the third groove 3-1.

The splicing block 4 supports, connects and disassembles the surface settlement monitoring point protection device.

[0033] The guard wall 2, adapter body 3 and splicing block 4 are in an enclosed state. The first groove 2-2 of the main guard wall 2 and the third mounting ring 4-2 of the splicing block 4 are connected by a first pin, the second groove 2-3 of the main guard wall 2 and the first mounting ring 3-2 of the adapter body 3 are connected by a second pin, and the third groove 3-1 of the adapter body 3 and the second mounting ring 4-1 of the splicing block 4 are connected by a third pin, thereby enclosing a cylinder a.

[0034] The installation and recovery method of the surface settlement monitoring point protection device is as follows:

[0035] Step 1: Use a water drill to drill a hole at the designed monitoring point and clean the bottom of the hole until it is flat, forming an installation hole with a height of 50mm-100mm and a diameter of 140mm-160mm.

[0036] Step 2: Use an electric drill to drill a hole in the center of the installation hole, then use an air drill to insert the steel bar into the hole vertically from the ground until the top of the steel bar is 2cm-5cm lower than the opening of the installation hole.

[0037] Step 3: Enclose and assemble the protective wall 2, the adapter 3 and the splicing block 4 into a cylinder.

[0038] Step 4: Place the cylinder into the installation hole in Step 1, cover it with top cover 1, and fill the gap between the installation hole and the cylinder with fine sand to secure it. This completes the installation of the surface settlement monitoring point protection device. During the project monitoring period, when settlement needs to be checked, open top cover 1 and use leveling to check the settlement of the settlement monitoring point.

[0039] Step 5: After the engineering monitoring period is over, use pliers to pull out the pin of the surface settlement monitoring point protection device, push the splicing block 4 and the adapter 3 inward, so that the surface settlement monitoring point protection device is disassembled and its diameter becomes smaller.

[0040] Step 6: After the surface settlement monitoring point protection device is decomposed and its diameter becomes smaller, it can be easily taken out of the installation hole, and then asphalt is backfilled in the installation hole until the surface is leveled, thereby completing the recovery of the surface settlement monitoring point protection device.

[0041] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.
