Description

Technical Field

[0001] The utility model belongs to the technical field of anchor cables, and in particular relates to a recoverable anchor cable structure for reinforcement. Background Art

[0002] Anchor cables are one of the most commonly used components in geotechnical engineering. In recent years, with the large-scale construction of projects, thousands of foundation pits are added every year in China, which in turn generates a large number of anchor cables. However, most of these anchor cables are needed for temporary support. If they are left underground for a long time after use, many problems will arise. In minor cases, they will form underground garbage and cause environmental pollution, and in severe cases, they will cause harm to surrounding construction. Considering factors such as long-term urban planning and sustainable development, many cities in China have banned the use of anchor cables in construction projects such as foundation pits.

[0003] In the prior art, in order to avoid the pollution caused by the anchor cable, a recyclable anchor cable is set in the anchor hole. The structure of this type of anchor cable usually includes a recovery cable. The recovery cable is subsequently dragged or pulled to release the position limit of each anchor cable, thereby realizing the recovery of the anchor cable. For example, the application number is: CN202320939152.2; the patent name is: A recyclable prestressed anchor cable. In the actual installation process of this structure, the recovery cable is easily released from the position limit of the anchor cable due to external force. Special attention should be paid to avoid the recovery cable to prevent the recovery cable from being accidentally pulled, which makes the installation process time-consuming and labor-intensive, and has poor practicality.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Please also read Figure 1 and Figure 2 , the reinforcing recyclable anchor cable structure provided by the utility model is now described. The reinforcing recyclable anchor cable structure comprises a constant resistance embedded seat 10, an anchor cable 20, a sliding limiter 30 and a water pipe 40. The constant resistance embedded seat 10 can be lowered and fixed in the anchor hole. The constant resistance embedded seat 10 has a receiving cavity 11. A plurality of anchor cables 20 are provided, and each anchor cable 20 is arranged in the anchor hole in a ring-shaped interval around the axis of the anchor hole, and one end of each anchor cable 20 passes through the constant resistance embedded seat 10 and extends into the receiving cavity 11. A plurality of sliding limiters 30 are provided, and each sliding limiter 30 is slidably arranged in the receiving cavity 11, and is detachably connected to each anchor cable 20. The water pipe 40 is arranged in the anchor hole, and is arranged colinearly with the axis of the anchor hole. One end of the water pipe 40 is detachably connected to the constant resistance embedded seat 10, and is communicated with the receiving cavity 11.

[0029] Specifically, water is injected into the accommodating chamber 11 through the water conduit 40 to push each sliding limiter 30 to move, so that each sliding limiter 30 releases the locking of each anchor cable 20 .

[0030] The water injection into the water guide pipe 40 can be performed by a high-pressure water pump.

[0031] Compared with the prior art, the reinforcing retractable anchor cable structure provided in the present embodiment has a constant resistance embedded seat 10 which can ensure the anchoring effect, and a plurality of sliding limit members 30 arranged in the accommodating cavity 11 can ensure the connection of a plurality of anchor cables 20, and a water pipe 40 can ensure that water is injected into the accommodating cavity 11 outside the anchor hole, so as to drive each sliding limit member 30 by water pressure, thereby releasing the connection of each sliding limit member 30 to the anchor cable 20. This structure can change the structure of the previous recovery cable, does not require dragging or pulling, is easy to install, and is highly practical.

[0032] In some embodiments, the accommodating cavity 11 may be formed as follows: Figure 2 See the structure shown. Figure 2 The accommodating chamber 11 includes a cylindrical space 111 colinear with the axis of the anchor hole and a plurality of sliding spaces 112 connected to the cylindrical space 111. The sliding spaces 112 are arranged in annular intervals around the cylindrical space 111, and the length direction of each sliding space 112 is arranged along the radial direction of the cylindrical space 111. Each sliding space 112 can be slidably connected to each sliding stopper 30.

[0033] The cylindrical space 111 can be easily processed and manufactured, and can adapt to the distribution of the anchor cables 20 , while the sliding space 112 can ensure the sliding connection of the sliding stoppers 30 .

[0034] Specifically, the sliding space 112 may be a cylindrical cavity or a square cavity.

[0035] It should be noted that the constant resistance embedded seat 10 may include a main seat body and an end cover threadedly connected to the main seat body. The specific accommodating cavity 11 needs to be formed by the two. Figure 1 .

[0036] In some embodiments, the anchor cable 20 may be Figure 1 See the structure shown. Figure 1 Each anchor cable 20 includes a connecting column 21 and a stranded wire 22. The connecting column 21 is slidably arranged on the constant resistance embedded seat 10 along the axial direction of the cylindrical space 111, and one end of the stranded wire 22 extends into the cylindrical space 111. The stranded wire 22 is arranged in the anchor hole, and one end of the stranded wire 22 is fixedly connected to the other end of the connecting column 21.

[0037] The connecting column 21 and the stranded wire 22 are combined to form the anchor cable 20. The connecting column 21 can ensure the sliding effect with the constant resistance embedded seat 10, reduce the friction between the pattern on the outer edge of the stranded wire 22 and the constant resistance embedded seat 10, and thus ensure the smooth recovery of the anchor cable 20. The connecting column 21 and the stranded wire 22 can be welded or integrally connected.

[0038] In some embodiments, the sliding stopper 30 may be configured as follows: Figure 2 See the structure shown. Figure 2Each sliding stopper 30 includes a piston 31 and a plug-in column 32. The piston 31 is slidably disposed in the corresponding sliding space 112. The plug-in column 32 is fixed on the piston 31 and arranged along the radial direction of the cylindrical space 111, and one end of the plug-in column 32 is inserted into the socket provided on the corresponding connecting column 21.

[0039] The piston 31 can be slidably arranged in the sliding space 112 and arranged along the radial direction of the cylindrical space 111 , so as to drive the corresponding plug-in column 32 to move, so as to ensure a detachable connection with each anchor cable 20 .

[0040] It should be noted that the axial direction of each socket is perpendicular to the axial direction of the corresponding connecting column 21 .

[0041] The piston 31 divides the sliding space 112 into a water inlet chamber connected to the cylindrical space 111 and a buffer chamber located on the other side of the piston 31 . A plurality of air holes connected to the buffer chamber may be provided on the constant resistance embedded seat 10 to ensure stable sliding of the sliding limiter 30 .

[0042] In some embodiments, the piston 31 may be Figure 2 See the structure shown. Figure 2 A sealing ring 33 is provided on the outer edge surface of the piston 31. This structure can ensure the sealing effect and thus avoid water pressure failure.

[0043] In some embodiments, the plug-in column 32 may be used as follows: Figure 1 See the structure shown. Figure 1 Each plug-in column 32 is in contact with the end surface of the cylindrical space 111, which can ensure that the tension of the anchor cable 20 acts directly on the end surface of the cylindrical space 111 through the plug-in column 32, thereby ensuring the stability of the anchor cable 20 and preventing the piston 31 from being subjected to torque.

[0044] In some embodiments, the constant resistance embedded seat 10 can be used as follows Figure 1 See the structure shown. Figure 1 The constant resistance embedded seat 10 is provided with a connection port 12 which is connected to the cylindrical space 111 and for threaded connection of the water pipe 40. This structure can ensure that the water pipe 40 can be disassembled after the anchor cable 20 is recovered. It only needs to rotate the water pipe 40, which is easy to operate.

[0045] In some embodiments, see Figure 1 The reinforcing recyclable anchor cable structure further includes a plurality of auxiliary sleeves 50 respectively sleeved on each anchor cable 20 . The auxiliary sleeves 50 can ensure the protection of the anchor cables 20 and also facilitate the recovery of the anchor cables 20 .
