Description

Technical Field

[0001] The invention relates to the technical field of slope anchor cable reinforcement, and in particular to a pressure dispersive slope anchor cable structure. Background Art

[0002] Slope anchor cable is a prestressed steel strand used for slope reinforcement. One end of the cable is fixed to the slope surface, and the other end is anchored in the stable rock mass within the sliding surface. This reinforcement method plays an important role in slope management. It mainly passes through the slope sliding surface and directly generates anti-sliding resistance on the sliding surface, thereby enhancing the anti-sliding friction resistance. The anchor cable is mostly made of seven strands of steel strands. During the construction process, it is first necessary to drill holes on the slope. The depth of the drilling hole should not be less than the designed length of the anchor cable. After the drilling is completed, the anchor cable is placed in the drill hole, and then cement slurry is injected for anchoring.

[0003] When constructing slope anchor cables, the anchor cables are usually composed of multiple steel strands, which are generally provided with multiple anchor heads. The anchor heads are generally bearing plates, on which strand holes are provided. The steel strands pass through the strand holes and a pier head larger than the strand holes is fixed at the rear end. During operation, the steel strands transfer stress to the anchor heads, which transfer stress to the concrete, and the concrete then disperses and transfers the stress to the rock mass around the anchor holes.

[0004] In the process of the anchor head transferring prestress to the concrete, the anchor head exerts a large pressure on the local concrete due to the small transfer area of ​​the load stress, which will cause the problem of stress concentration. The deeper into the rock mass, the greater the stress will be. Stress concentration may lead to insufficient local strength of the anchor cable, thus affecting the stability of the entire anchor cable system.

[0005] In order to solve the above problems, this application proposes a pressure dispersing slope anchor cable structure. Summary of the invention

[0006] The present invention proposes a pressure-dispersing slope anchor cable structure, which solves the problem in the related art that in the process of the anchor head transferring prestress to concrete, the anchor head exerts a large pressure on the local concrete due to the small transfer area of ​​the load stress, resulting in stress concentration.

The push rod is arranged in a fixed cylinder. The push rod slides through one end of the fixed cylinder and is connected to the outer periphery of the bag sleeve.

[0016] As a further optimization solution of the present invention, the inner wall of the expansion ring is connected with an annular liner.

[0017] As a further optimization scheme of the present invention, the air supply assembly includes an air pump, an air supply hose and a shunt pipe. The shunt pipe passes through multiple first cone heads and second cone heads and is located between multiple steel ropes. Multiple air guide tubes are connected to the shunt pipe, and the multiple air guide tubes are respectively connected to multiple bag sleeves. One end of the air supply hose is connected to one end of the shunt pipe, and the air pump is connected to the end of the air supply hose away from the shunt pipe.

[0018] As a further optimization solution of the present invention, valve bodies are installed on the plurality of air guide pipes.

[0019] As a further optimization solution of the present invention, a positioning shaft fixed on a plurality of steel ropes is installed on the side of the loading plate.

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. The present invention first performs drilling operations on the slope. After the drilling is completed, the steel strand and the double-cone assembly thereon are placed into the drilled hole. The loading plate on the steel strand is fixed on the slope surface. Then, air is supplied to the bag assembly through the air supply assembly. The bag assembly expands under the action of air pressure and pushes the annular expansion plug assembly to be inserted into the rock body. Then, cement slurry is injected into the hole. The double-cone assembly consists of a first cone head and a second cone head to form a double-cone structure. This structure enables the double-cone assembly to have a gradually changing contact area when in contact with the steel strand and concrete. When stress is transmitted from the steel strand to the double cone, the double-cone assembly is When the double-cone assembly is used, the first cone head of the double-cone assembly will transfer part of the stress to the concrete. During use, the second cone head of the double-cone assembly will further disperse the stress to a wider concrete area. This multi-stage dispersion method gradually reduces the stress during the transmission process, avoiding the problem of excessive local stress. The double-cone assembly of this structure can effectively expand the stress transfer area between the anchor cable and the concrete. Compared with the traditional method of transferring stress only through the anchor head, the double-cone assembly can disperse the stress on the steel strand to a larger area, thereby reducing the local stress concentration phenomenon;

[0022] 2. When the present invention supplies air to the bag sleeve assembly through the air supply assembly, the bag sleeve assembly can be expanded by the air pressure, so that the bag sleeve assembly contacts the rock mass. Since a small steel ball is arranged in the bag sleeve body, the friction between the bag sleeve body and the rock mass can be increased. Since the stress is greater as the depth of the rock mass increases, a valve body is arranged on the air supply assembly, and the air entering the bag sleeve assembly near the deep rock mass can be controlled by the valve body, so that more air can enter the bag sleeve assembly deep in the rock mass, so that the expansion degree is greater, thereby better contacting the rock mass and enhancing the contact tightness with the rock mass. The air volume of the bag sleeve assembly far from the deep rock mass is relatively small, and decreases from the deep rock mass to the slope surface. This design makes full use of the small steel ball arranged in the bag sleeve body, further increases the friction between the bag sleeve body and the rock mass, so that the bag sleeve assembly can form a stable contact and anchoring with the rock mass at different positions, effectively improving the anchoring effect of the anchor cable in the rock mass, enhancing the overall stability of the anchor cable system, enabling it to better withstand the load stress of the slope, adapt to the complex rock mass environment, and improve the reliability and safety of slope anchor cable construction;

[0023] 3. The bag assembly of the present invention expands under the action of air pressure, which can push the rod-type liquid pushing part on the annular expansion plug assembly to move, so that the spiked plug rod connected to the rod-type liquid pushing part is inserted into the rock body. This structural design makes the anchor cable more firmly anchored in the rock body. The insertion of the spiked plug rod further enhances the bonding strength between the anchor cable and the rock body, improves the pull-out resistance of the anchor cable system, and can better resist the influence of adverse factors such as slope sliding. Under complex geological conditions, this enhanced anchoring effect can effectively ensure the stability of the anchor cable system, provide strong support for the long-term stability of the slope, reduce the risk of slope instability, and improve the safety and reliability of slope anchor cable construction;

[0024] 4. When the present invention injects cement slurry into the borehole, the moisture in the cement slurry can be absorbed by the expansion ring on the annular expansion plug-in assembly. The expansion ring can expand after absorbing water, thereby increasing the contact area and friction with the rock mass. This design makes the cement slurry more tightly bonded to the expansion ring and the rock mass during the solidification process, further enhancing the integrity between the anchor cable and the rock mass and improving the anchoring effect of the anchor cable system. At the same time, the expansion effect of the expansion ring can also play a certain supporting and filling role on the cement slurry, making the cement slurry more evenly distributed in the borehole, further improving the anchoring quality of the anchor cable, enhancing the stability of the anchor cable system, and reducing problems such as loosening of the anchor cable caused by uneven solidification of the cement slurry or loose bonding with the rock mass, providing a higher quality anchoring guarantee for the slope anchor cable construction and effectively improving the stability and safety of the slope.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0039] like Figure 1-12 As shown, a pressure dispersive slope anchor cable structure proposed by the present invention comprises a loading plate 1, a plurality of steel strands 101, a plurality of double-conical components 2 and an air supply component 5;

[0040] A plurality of steel strands 101 are fixed on the loading plate 1, and a plurality of double-cone assemblies 2 are installed on the plurality of steel strands 101 at intervals;

[0041] The outer circumferences of the multiple double-cone components 2 are all covered with a bag cover component 3, and the outer circumferences of the bag cover component 3 are covered with an annular expansion plug-in component 4;

[0042] The air supply component 5 is connected to the multiple bag assembly 3 and is used to supply air to the multiple bag assembly 3. When the air supply component 5 supplies air to the bag assembly 3, the bag assembly 3 expands due to the air pressure and pushes the annular expansion plug-in component 4 to be inserted into the rock mass.

[0043] First, drill a hole in the slope, fix the loading plate 1 on the slope, put the steel strand 101 and the connected components into the hole, and the air supply component 5 supplies air to the bag assembly 3. The bag assembly 3 expands and pushes the annular expansion plug assembly 4 to insert into the rock mass. Then, cement slurry is injected, and the double cone assembly 2 disperses the stress. The bag assembly 3 and the annular expansion plug assembly 4 further enhance the anchoring effect, and jointly ensure that the anchor cable stabilizes and reinforces the slope.

[0044] like Figure 2 , Figure 3 ,and Figure 4 As shown, in this embodiment, the double-cone component 2 includes a first cone head 21 and a second cone head 22, and the first cone head 21 and the second cone head 22 are interconnected and fixed on multiple steel strands 101, and the first cone head 21 and the second cone head 22 are oriented in the same direction; during the operation of the overall anchor structure, the first cone head 21 and the second cone head 22 of the double-cone component 2 work together to play a key role in stress transfer. When the steel strand 101 is subjected to stress, the first cone head 21 first disperses part of the stress to the concrete, and the second cone head 22 further disperses the stress to avoid stress concentration in local areas. Through this multi-stage transfer method, the stress transfer area between the anchor and the concrete is expanded, effectively reducing local stress concentration and improving the stability of the anchor system.

[0045] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in this embodiment, the bag sleeve assembly 3 includes a bag sleeve body 31, one end of the first cone head 21 and the second cone head 22 are both covered with the bag sleeve body 31, and densely arranged small steel balls 32 are arranged in the bag sleeve body 31. The annular expansion plug-in assembly 4 is mounted on the outer periphery of the bag sleeve body 31; after the air supply assembly 5 expands the bag sleeve body 31, the bag sleeve body 31 contacts the rock mass, and the internal small steel balls 32 will roll between the bag sleeve body 31 and the rock mass, increasing the friction between the two, enhancing the anchoring effect of the bag sleeve assembly 3 and the rock mass, making the anchor cable more stable in the rock mass, and improving the ability of the anchor cable system to resist external forces.

[0046] like Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, the annular expansion plug assembly 4 includes an expansion ring 41, which is sleeved on the outer periphery of the bag sleeve 31. The expansion ring 41 is a water-swelling waterproof rubber ring. A plurality of connectors 42 arranged circumferentially and connected to the outer periphery of the bag sleeve 31 are installed on the expansion ring 41; when the bag sleeve 31 expands, it pushes the expansion ring 41, and the expansion ring 41 drives the connector 42 to move toward the rock mass. The connector 42 is inserted into the rock mass, which increases the anchoring points between the anchor cable and the rock mass, improves the pull-out resistance of the anchor cable system, and makes the anchor cable more firmly fixed in the rock mass. Since the expansion ring 41 is a water-swelling waterproof rubber ring, when the cement slurry contacts the expansion ring 41, the expansion ring 41 can expand and harden.

[0047] like Fig.10 , Fig.11 and Fig.12 As shown, in this embodiment, the connector 42 includes a fixed tube 421, and a plurality of circumferentially arranged fixed tubes 421 are installed on the expansion ring 41. A rod-type liquid pushing portion 422 is slidably provided in the fixed tube 421, and the rod-type liquid pushing portion 422 is connected to the outer periphery of the bag sleeve 31, and a spiked plug rod 423 is connected to the rod-type liquid pushing portion 422, and one end of the spiked plug rod 423 slides through the end of the fixed tube 421 away from the expansion ring 41; the bag sleeve 31 expands and pushes the rod-type liquid pushing portion 422 to slide in the fixed tube 421, and the rod-type liquid pushing portion 422 drives the spiked plug rod 423 to move toward the rock mass, and finally the spiked plug rod 423 is inserted into the rock mass. The insertion of the spiked plug rod 423 into the rock mass enhances the bonding strength between the anchor cable and the rock mass, further improves the pull-out resistance of the anchor cable system, and ensures the stability of the anchor cable under complex geological conditions.

[0048] like Fig.12 As shown, in this embodiment, the rod-type liquid pushing part 422 includes a push rod 4221, a first piston 4222 and a second piston 4223. The push rod 4221 is arranged in the fixed cylinder 421, and the push rod 4221 slides through one end of the fixed cylinder 421 and is connected to the outer periphery of the bag sleeve body 31. The push rod 4221 is fixed with the first piston 4222 and the second piston 4223 located in the fixed cylinder 421. The other end of the spiked plug rod 423 is connected to the second piston 4223. The first piston 4222 and the second piston 4223 are connected to each other. A liquid storage area is formed between the plugs 4223, and adhesive liquid is stored in the liquid storage area. A plurality of openings 424 arranged circumferentially are provided on the fixed cylinder 421. When the air supply assembly 5 supplies air to the bag assembly 3, the bag assembly 3 expands under the action of air pressure, pushing the push rod 4221 to drive the first piston 4222 and the second piston 4223 to move in the fixed cylinder 421. The adhesive liquid between the first piston 4222 and the second piston 4223 is discharged through the opening 424, and the spiked rod 423 is inserted into the rock mass.

[0049] The expansion of the bag assembly 3 pushes the push rod 4221 to move, and the push rod 4221 drives the first piston 4222 and the second piston 4223 to slide in the fixed cylinder 421, so that the adhesive liquid between the first piston 4222 and the second piston 4223 is discharged from the opening 424, and at the same time, the spike rod 423 is inserted into the rock mass. After the adhesive liquid is discharged, it fills the gap between the spike rod 423 and the rock mass. After solidification, the connection strength between the anchor cable and the rock mass is further enhanced, thereby improving the stability and reliability of the anchor cable system.

[0050] like Fig.10 As shown, in this embodiment, the inner wall of the expansion ring 41 is connected to an annular lining 43; the annular lining 43 mainly plays a protective and auxiliary role. During the expansion process of the expansion ring 41, it can prevent the inner wall of the expansion ring 41 from being worn, and at the same time, it can also make the contact between the expansion ring 41 and the bag body 31 closer, thereby extending the service life of the expansion ring 41, ensuring the stability of the expansion ring 41 during operation, and indirectly improving the overall performance of the anchor system.

[0051] like Figure 1 and Figure 4 As shown, in this embodiment, the air supply assembly 5 includes an air pump 51, an air supply hose 52 and a shunt pipe 53. The shunt pipe 53 passes through the plurality of first cone heads 21 and the second cone heads 22 and is located between the plurality of steel strands 101. The shunt pipe 53 is connected to a plurality of air guide tubes 54, and the plurality of air guide tubes 54 are respectively connected to the plurality of bag sleeves 31. One end of the air supply hose 52 is connected to one end of the shunt pipe 53, and the air pump 51 is connected to the end of the air supply hose 52 away from the shunt pipe 53.

[0052] After the air pump 51 is started, high-pressure gas is generated. The gas enters the shunt pipe 53 through the air supply hose 52, and is then transported to each bag sleeve body 31 by the shunt pipe 53 through the air guide pipe 54, providing a stable air source for the bag sleeve assembly 3, ensuring that the bag sleeve assembly 3 can expand smoothly, and driving the annular expansion plug-in assembly 4 to work. It is the power source for the entire anchor cable structure to realize the anchoring function.

[0053] like Figure 4 As shown, in this embodiment, valve bodies 541 are installed on the multiple air guide tubes 54; by controlling the opening and closing degree of the valve bodies 541, the amount of gas entering each bag body 31 can be adjusted. For the bag body 31 close to the deep rock mass, the valve body 541 can be opened to increase the amount of gas entering. For the bag body 31 close to the slope, the valve body 541 is closed to reduce the amount of gas entering, so that the bag assembly 3 at different positions can expand to different degrees according to the stress of the rock mass, better contact with the rock mass, enhance the anchoring effect of the anchor cable at different depths, and improve the adaptability of the anchor cable system.

[0054] like Figure 1 and Figure 2As shown, in this embodiment, a positioning shaft 102 fixed on a plurality of steel strands 101 is installed on the side of the loading plate 1; when installing the anchor cable, the positioning shaft 102 is used to determine the position of the steel strands 101, to ensure that the relative positions of the plurality of steel strands 101 are fixed, to prevent the steel strands 101 from being entangled or shifted in position in the borehole, to improve the accuracy and efficiency of the anchor cable installation, to ensure that the various components of the anchor cable can be correctly installed and work together, and to ensure the stability of the anchor cable system.

[0055] The specific working principle of the present invention is as follows:

[0056] After the drilling operation is completed on the slope, the loading plate 1 is fixed on the slope surface, and multiple steel strands 101 and multiple double-cone components 2 installed thereon at intervals are placed into the drilled hole. At this time, the positioning shaft 102 plays a role. It is installed on the side of the loading plate 1 and fixed on the steel strands 101 to ensure that the relative positions of the steel strands 101 are fixed, avoid entanglement or deviation in the drilled hole, and improve the installation accuracy and efficiency. Then, the air supply component 5 is started, and the high-pressure gas generated by the air pump 51 enters the shunt pipe 53 through the air supply hose 52, and is then transported to each bag sleeve body 31 through the multiple air guide pipes 54 connected to the shunt pipe 53. The air guide pipe 5 The valve body 541 installed on 4 can adjust the amount of gas entering the bag sleeve body 31 according to the stress conditions at different depths of the rock mass, so that the bag sleeve assembly 3 close to the deep rock mass can enter more air to make it expand to a greater extent, and the amount of air in the bag sleeve assembly 3 far away from the deep rock mass is relatively small, and it decreases from the deep rock mass to the slope surface. The bag sleeve assembly 3 expands under the action of air pressure, and the small steel balls 32 densely arranged in the bag sleeve body 31 increase the friction with the rock mass, and at the same time push the annular expansion plug assembly 4 to be inserted into the rock mass. The expansion ring 41 in the annular expansion plug assembly 4 is sleeved on the outer periphery of the bag sleeve body 31, and the plug 42 on the expansion ring 41 moves accordingly;

[0057] In the fixed cylinder 421 of the connector 42, the rod-type liquid pushing part 422 slides under the push of the expansion of the bag sleeve body 31, and the push rod 4221 of the rod-type liquid pushing part 422 drives the first piston 4222 and the second piston 4223 to move in the fixed cylinder 421, so that the adhesive liquid in the liquid storage area between the first piston 4222 and the second piston 4223 is discharged through the opening 424 on the fixed cylinder 421, and at the same time, the spiked plug rod 423 is inserted into the rock mass, thereby enhancing the bonding strength and pull-out resistance of the anchor cable and the rock mass. The double-cone component 2 is composed of a first cone head 21 and a second cone head 22. When the stress is transmitted from the steel strand 101 to the double-cone component 2, the first cone head 21 first transmits part of the stress to the concrete, and the second cone head 22 further disperses the stress to a wider concrete area, thereby expanding the stress transmission area and reducing local stress concentration.

[0058] Finally, cement slurry is injected into the borehole, and the expansion ring 41 expands after absorbing the water in the cement slurry, thereby increasing the contact area and friction with the rock mass, so that the cement slurry is more closely combined with the rock mass during the solidification process, supporting and filling the cement slurry, making the cement slurry more evenly distributed in the borehole, and improving the anchoring quality of the anchor cable and the stability of the system.

[0059] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
