Description

Technical Field

[0001] The present application relates to the technical field of slope support, and in particular to a high and steep slope support structure. Background Art

[0002] Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its environment. High and steep slope support is a common type of slope support. Commonly used support structure types include: gravity retaining wall, buttress retaining wall, cantilever support, plate rib or lattice anchor retaining wall support, pile anchor retaining wall support, anchor spraying support, and slope method.

[0003] The patent document with the published announcement number CN209129004U provides a high and steep slope support structure, including a slope body, a slope surface of the slope body being a 45-degree slope surface, and a slope step being provided on the slope surface, and the slope step being evenly spaced along the height direction on the slope surface, and the slope body being supported by anchor cables and anchor rods combined with grouting, and the anchor cables being evenly spaced along the horizontal and vertical directions on the slope surface, and the distance between two adjacent anchor cables being 1m, and anchor rods being provided in the middle positions of the two adjacent anchor cables, and a trench being provided along the bottom of the slope surface, and the surfaces of the slope surface, the slope step and the trench being sprayed with a concrete layer, which can solve the problems of difficult slope maintenance and great safety hazards of high and steep slopes due to inconvenient transportation in mountainous areas, changeable climate and water disasters at this stage.

[0004] The above-mentioned slope support structure fixes the support mechanism by anchor cables and anchor rods. When the anchoring effect of some anchor rods fails, it will affect the effective fixation of the overall structure and pose a safety hazard. However, the above-mentioned structure lacks corresponding measures to monitor whether the anchoring effect of the anchor rods is effective. This leads to the possibility that the local anchoring effect of the slope support structure may fail without being discovered in time, eventually causing the entire slope support structure to become unstable. Therefore, a high and steep slope support structure is proposed to address the above-mentioned problem. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a high and steep slope support structure, which overcomes the deficiencies of the prior art and aims to solve the problem that the existing high and steep slope support structure lacks corresponding measures to monitor whether the anchoring effect of local anchor rods fails.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A high and steep slope support structure comprises a slope protection structure, an anchoring structure and a displacement measuring mechanism, wherein the anchoring structure and the displacement measuring mechanism are both fixedly arranged at the rear side of the slope protection structure, the displacement measuring mechanism comprises a measuring component and a pull-connection seat pre-buried in the slope protection structure, the measuring component is electrically connected to a data transmission line, a pull-connection fixing rod is fixedly connected to the rear end face of the measuring component, the end of the pull-connection fixing rod is anchored in the soil through a grouting anchor section, and the connecting shaft of the measuring component is fixedly connected to the pull-connection seat through a transmission connecting piece.

At the same time, the displacement measuring mechanism anchored in the soil is connected to the slope protection structure. When part of the anchoring structure fails, the local slope protection structure will deform and displace under the action of soil pressure. At this time, the measuring component will monitor the position information and transmit the information to the monitoring station through the data transmission line. By comparison, it can be determined whether the anchoring effect of the anchoring structure at this location has failed, which can play a preventive role and improve safety.

When the connecting shaft is fixedly connected to the slope protection structure, when the slope protection structure is displaced, it will drive the connecting shaft to move, thereby realizing the displacement change of the slope protection structure monitored by the linear displacement sensor, and then judging whether the anchoring of the anchoring structure has failed. The waterproof and sealed casing and the sealed cylinder can protect the linear displacement sensor and prevent the humid environment of the soil from damaging the linear displacement sensor.

[0011] As a preferred technical solution of the present application, the transmission connecting part includes a threaded sleeve threadedly connected to the connecting shaft of the linear displacement sensor, the front end of the threaded sleeve is fixedly connected to a connecting screw, the front part of the connecting screw is located at the rear side of the pull-connector seat and is fixed with a positioning end plate, and the front end of the connecting screw is threadedly connected to a locking nut.

[0013] As a preferred technical solution of the present application, the anchoring structure includes a pull rod, the end of which is anchored in the soil through a grouting anchoring section, the front end of the pull rod passes through the slope protection structure and extends out, the front end of the pull rod is threadedly connected with a fastening nut, and a gasket is provided on the pull rod outer sleeve on the rear side of the fastening nut.

[0014] By adopting the above technical solution, the slope protection structure can be restricted from moving forward by tightening the nut and the gasket in combination. At the same time, under the pulling force of the pull rod, the slope protection structure will be firmly fixed on the slope surface of the steep slope to play a slope protection role.

[0015] As a preferred technical solution of the present application, the slope protection structure is cast by reinforced concrete material, which is composed of transversely arranged cross beams and longitudinally arranged longitudinal beams that are perpendicularly staggered to each other, and square through holes are formed between the cross beams and longitudinal beams.

[0016] By adopting the above technical solution, the overall weight of the slope protection structure can be reduced, and the stability of the slope can be prevented from being affected by excessive deadweight while playing a supporting role.

[0017] As a preferred technical solution of the present application, the data transmission line is a waterproof and moisture-proof cable buried in the soil of the slope, and the end of the data transmission line away from the slope protection structure is electrically connected to the equipment in the existing slope monitoring station or to the computer used for monitoring.

[0018] By adopting the above technical solution, the monitored displacement information can be transmitted to the outside via a data transmission line.

[0019] The beneficial effects of the present application are as follows: the slope protection structure can be anchored on the slope with an anchoring structure to play a role in slope protection, and at the same time, the displacement measuring mechanism anchored in the soil is connected to the slope protection structure. When part of the anchoring structure fails, the local slope protection structure will deform and displace under the action of soil pressure. At this time, the measuring component will monitor the position information and transmit the information to the monitoring station through the data transmission line. By comparison, it can be determined whether the anchoring effect of the anchoring structure at that location has failed, which can play a preventive role and improve safety.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Reference Figure 1-2 A high and steep slope support structure includes a slope protection structure 1, an anchoring structure 2 and a displacement measuring mechanism 3. The anchoring structure 2 and the displacement measuring mechanism 3 are both fixedly arranged at the rear side of the slope protection structure 1. The displacement measuring mechanism 3 includes a measuring component 31 and a pull-connection seat 35 pre-buried in the slope protection structure 1. The measuring component 31 is electrically connected to a data transmission line 32. A pull-connection fixing rod 33 is fixedly connected to the rear end face of the measuring component 31. The end of the pull-connection fixing rod 33 is anchored in the soil through a grouting anchor section 34. The connecting shaft of the measuring component 31 is fixedly connected to the soil through a transmission connecting member 36. By adopting the above-mentioned technical scheme, the slope protection structure 1 can be anchored on the slope by the anchoring structure 2 on the pull-connecting seat 35 to play a role in slope protection. At the same time, the displacement measuring mechanism 3 anchored in the soil is connected to the slope protection structure 1. When part of the anchoring structure 2 fails, the local slope protection structure 1 will deform and displace under the action of soil pressure. At this time, the measuring component 31 will monitor the position information and transmit the information to the monitoring station through the data transmission line 32. By comparison, it can be determined whether the anchoring effect of the anchoring structure 2 at this location has failed, which can play a preventive role and improve safety.

[0027] In addition, the slope protection structure 1 is cast with reinforced concrete material, and is composed of transversely arranged cross beams and longitudinally arranged longitudinal beams that are perpendicularly staggered with each other, and square through holes are formed between the cross beams and longitudinal beams. This structural form can reduce the overall weight of the slope protection structure 1, and can avoid excessive deadweight that affects the stability of the slope while playing a supporting role. The data transmission line 32 is a waterproof and moisture-proof cable buried in the soil of the slope, and the end of the data transmission line 32 away from the slope protection structure 1 is electrically connected to the equipment in the existing slope monitoring station or to the computer used for monitoring, and the monitored displacement information can be transmitted to the outside via the data transmission line 32.

[0028] Reference Figure 3 The measuring component 31 includes a waterproof and sealed shell 311, in which a linear displacement sensor 312 is fixedly arranged, and a sealed tube 313 is fixedly arranged on the front end surface of the waterproof and sealed shell 311. The connecting shaft of the linear displacement sensor 312 is slidably arranged in the sealed tube 313. When the connecting shaft of the linear displacement sensor 312 slides back and forth, the linear displacement sensor 312 will monitor the information of the displacement change. After the connecting shaft is fixedly connected to the slope protection structure 1, when the slope protection structure 1 is displaced, it will drive the connecting shaft to move, thereby realizing the displacement change of the slope protection structure 1 through the linear displacement sensor 312, and then judging whether the anchoring of the anchoring structure 2 fails. The waterproof and sealed shell 311 and the sealed tube 313 can protect the linear displacement sensor 312 and prevent the humid environment of the soil from damaging the linear displacement sensor 312.

[0029] Reference Figure 3 The transmission connecting member 36 includes a threaded sleeve 361 threadedly connected to the connecting shaft of the linear displacement sensor 312, and a connecting screw 362 is fixedly connected to the front end of the threaded sleeve 361. The front part of the connecting screw 362 is located at the rear side of the pull-connection seat 35 and is fixedly sleeved with a positioning end piece 363. The front end of the connecting screw 362 is threadedly connected to a locking nut 364. By adopting the above technical scheme, after the slope protection structure 1 is fixedly connected to the anchor structure 2, that is, when the position of the slope protection structure 1 is fixed, the connecting screw 362 is connected to the connecting shaft of the linear displacement sensor 312 through the threaded sleeve 361, and the positioning end piece 363 is pressed against the rear end surface of the pull-connection seat 35, and then the locking nut 364 and the positioning end piece 363 are combined to work to fix the connecting screw 362 and the pull-connection seat 35. At this time, the displacement of the slope protection structure 1 will be synchronously transmitted to the connecting shaft of the linear displacement sensor 312.

[0030] Reference Figure 4The anchoring structure 2 includes a tie rod 21, the end of which is anchored in the soil through a grouting anchoring section 22, the front end of the tie rod 21 passes through the slope protection structure 1 and extends out, the front end of the tie rod 21 is threadedly connected with a fastening nut 24, and a gasket 23 is provided on the outer sleeve of the tie rod 21 on the rear side of the fastening nut 24. By adopting the above technical solution, the slope protection structure 1 can be restricted from moving forward through the combination of the fastening nut 24 and the gasket 23. At the same time, under the pulling force of the tie rod 21, the slope protection structure 1 will be firmly fixed on the slope surface of the high and steep slope to play a slope protection role.

[0031] Working principle: After the slope protection structure 1 is cast, the combination of the fastening nut 24 and the gasket 23 can be used to restrict the slope protection structure 1 from moving forward. At the same time, under the pulling force of the pull rod 21, the slope protection structure 1 will be firmly fixed on the slope surface of the high and steep slope to play a role in slope protection. After the slope protection structure 1 is fixedly connected with the anchor structure 2, that is, when the position of the slope protection structure 1 is fixed, the connecting screw 362 is connected to the connecting shaft of the linear displacement sensor 312 through the threaded sleeve 361, and the positioning end piece 363 is pressed against the rear end face of the pull-connecting seat 35, and then the locking nut 364 is used to tighten the positioning end piece 3 The 63 combination works to fix the connecting screw 362 and the pull-connecting seat 35. At this time, the displacement of the slope protection structure 1 will be synchronously transmitted to the connecting shaft of the linear displacement sensor 312. When the connecting shaft of the linear displacement sensor 312 slides back and forth, the linear displacement sensor 312 will monitor the displacement change information. After the connecting shaft is fixedly connected to the slope protection structure 1, when the slope protection structure 1 is displaced, it will drive the connecting shaft to move, thereby realizing the displacement change of the slope protection structure 1 through the linear displacement sensor 312, and then judging whether the anchoring of the anchoring structure 2 has failed, which can play a preventive role and improve safety.
