Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, it is applied to recyclable prestressed anchor cables in waste soil. Background Technology

[0002] To meet the needs of foundation pit support in different areas, the main foundation pit support methods include: pile anchor support, slope protection, anchor spraying support, retaining pile support, pile bracing support, and cantilever pile support. When carrying out pile anchor construction, the existing anchor cable recycling technology is used for support. However, this method cannot guarantee the anchoring strength and recycling success rate of recyclable anchor cables in the waste soil layer.

[0003] Patent document CN116357364A discloses a recyclable prestressed anchor cable, which includes an anchor cable assembly, a support, and a connecting assembly. The anchor cable assembly includes steel strands and a recyclable cable. The steel strands include a free section and an anchoring section separated from each other. The support has grouting holes and mounting holes. The connecting assembly includes a connecting part and a conical first clamping member. The connecting part is embedded in the mounting hole and forms an inner cavity. The inner cavity includes a first end and a second end arranged opposite to each other. The free section is installed at the first end, and the second end is tapered along a first direction. This recyclable prestressed anchor cable can provide support for slopes, foundation pit walls, mine shafts, and other areas. The support and recycling principle is simple, the manufacturing is easy, the structure is simple, the operation is convenient, and it is easy to recycle. It can be reused multiple times, thus improving the value of the anchor cable.

[0004] The aforementioned recyclable prestressed anchor cables have certain shortcomings in use. When used in waste soil, the prestressed anchor cables cannot be properly fixed due to the influence of the waste soil itself. The ends of the prestressed anchor cables are fixed by pouring concrete structures, which cannot be used for temporary fixing operations, increasing the difficulty of recycling the prestressed anchor cables. Secondly, the aforementioned prestressed anchor cables do not have auxiliary recycling structures. The recycling methods for prestressed anchor cables are mainly mechanical, physical, and chemical, all of which involve breaking the steel strands and using jacks to apply pressure to pull them out. The recycling efficiency is low, and the recycled steel strands are easily damaged, making them unusable and reducing the recycling effect. Furthermore, the aforementioned prestressed anchor cables do not have splicing and assembly structures. When the prestressed anchor cables are repeatedly temporarily fixed, their fixing structures are easily damaged, thus affecting the fixing effect of the prestressed anchor cables. Summary of the Invention

[0005] The purpose of this invention is to provide recyclable prestressed anchor cables for use in landfill soil, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. When prestressed anchor cables are used in waste soil, the waste soil itself makes it difficult to fix the prestressed anchor cables in the waste soil. The ends of the prestressed anchor cables are fixed by pouring concrete structures, and temporary fixing operations are not possible, which increases the difficulty of recycling the prestressed anchor cables.

[0008] 2. Secondly, the above-mentioned prestressed anchor cables do not have an auxiliary recycling structure. The recycling methods of prestressed anchor cables are mainly mechanical, physical and chemical. They all involve breaking the steel strands and then using jacks to apply pressure to pull them out. The recycling efficiency is low, and the recycled steel strands are easily damaged and cannot be reused, which reduces the recycling effect.

[0009] 3. Secondly, the prestressed anchor cables mentioned above do not have a splicing and assembly structure. When the prestressed anchor cables are repeatedly subjected to temporary fixing operations, their fixing structure is prone to damage, thereby affecting the fixing effect of the prestressed anchor cables.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A recyclable prestressed anchor cable for use in landfill soil includes a conical anchor head, a reinforcing section, and several sets of steel strands. The conical anchor head is fixedly installed on the lower outer surface of the reinforcing section, and the several sets of steel strands are fixedly installed on the upper end of the reinforcing section. A protective sleeve is sleeved between the sets of steel strands and the reinforcing section. Side-rotating clamps are movably installed on both sides of the reinforcing section. The side-rotating clamps are movably connected to the reinforcing section via an elastic rotating shaft. The side-rotating clamps have an overall conical structure, and two sets of side-rotating clamps are symmetrically arranged. A control rope is connected to the upper end of the side-rotating clamps. A recycler for recycling operations is installed on the upper part of the several sets of steel strands. The recycler includes a limiting top plate and a pull-out plate. The pull-out plate is movably installed on the upper part of the limiting top plate, and the pull-out plate and the limiting top plate are driven by two hydraulic jacks.

[0012] As a further technical solution of the present invention, an upper chuck for connecting steel strands is spliced ​​and installed on the inner side of the pull plate, and a lower chuck for connecting steel strands is installed on the inner side of the limiting top plate. Both the upper and lower chucks have several sets of round holes on their inner sides. When the prestressed anchor is recycled, the limiting top plate and the pull plate of the recycling device are respectively passed through one end of the steel strand. The end of the steel strand is fixed by the pull plate and the fixing clip. The pull plate is driven to move up and down by the hydraulic jack. Each time the pull plate moves, the steel strand can be pulled out a certain distance. After repeating the operation several times, the entire steel strand can be pulled out, thereby completing the recycling operation of the prestressed anchor.

[0013] As a further technical solution of the present invention, a fixing clip for fixing the steel strand is provided in the circular hole of the upper chuck, and a roller is provided in the circular hole of the lower chuck. Support brackets are fixedly installed on both outer surfaces of the limiting top plate. The setting of the support brackets, together with the use of bolts, plays an auxiliary fixing role in the installation of the recycler. The fixing clip can clamp and fix both sides of the steel strand, making it convenient to pull out the steel strand.

[0014] As a further technical solution of the present invention, the fixing clip includes two sets of first clip plates and two sets of second clip plates. Both sets of first clip plates and two sets of second clip plates are inclined and symmetrical to each other. The steel strand and the reinforcing section are fixed by connecting and fixing with fixing clips. The reinforcing section is movably installed with guide wheels for use with control ropes. When the hydraulic jack drives the pull plate to move down, because both sets of first clip plates and two sets of second clip plates are designed with an inclined structure, the steel strand can pass upward through the two sets of first clip plates and two sets of second clip plates. The two sets of first clip plates and two sets of second clip plates constitute a double fixing structure.

[0015] As a further technical solution of the present invention, the first card plate and the second card plate are provided with a docking shaft in the middle. The first card plate, the second card plate and the upper chuck are movably connected by the docking shaft. By using the docking shaft, the first card plate and the second card plate can be in a side-rotating structure inside the upper chuck.

[0016] As a further technical solution of the present invention, a tension spring is movably installed at one end of the first and second clamping plates. One end of the first and second clamping plates is elastically connected to the side wall of the pull-out plate through the tension spring. The tension spring allows the first and second clamping plates to rotate actively to one end. During the use of the pull-out plate, the first and second clamping plates can be tightly attached to both sides of the steel strand. When the pull-out plate moves upward, one end of the first and second clamping plates rotates inward in coordination with the movement of the steel strand, so that the first and second clamping plates are clamped and fixed to both sides of the steel strand. When the first and second clamping plates fix the steel strand, one end of the first and second clamping plates abuts against each other, controlling the fixing angle of the first and second clamping plates and preventing the first and second clamping plates from damaging the steel strand.

[0017] As a further technical solution of the present invention, the other side of the first card plate and the second card plate are provided with arc-shaped grooves, and the inner side of the arc-shaped grooves is provided with several sets of arc-shaped teeth. The arc-shaped grooves and the arc-shaped teeth can improve the fixing effect of the first card plate and the second card plate and increase the friction between the first card plate, the second card plate and the steel strand.

[0018] As a further technical solution of the present invention, the side-rotating clamp includes a side-rotating base and a conical head. The conical head is spliced ​​and installed at one end of the side-rotating base. The side-rotating base and the conical head are spliced ​​and fixed by a threaded clamp. A rotating cap is provided at one end of the side-rotating base. The side-rotating clamp is set with an elastic rotating shaft, so that the side-rotating clamp has an elastic side-rotating structure. The opening and closing angle of the side-rotating clamp is adjusted by a control rope. When in use, the side-rotating clamp is loosened, so that the two sets of side-rotating clamps open outward. At the same time, the prestressed anchor is pulled, so that the side-rotating clamp rotates outward, so that one end of the side-rotating clamp is stuck in the garbage soil, thereby increasing its fixing effect.

[0019] As a further technical solution of the present invention, a second ring is movably sleeved on the outer surface of the steel strand, and a first ring is provided on the lower part of the second ring on the outer surface of the steel strand. Both the second ring and the first ring are provided with circular grooves. The circular grooves can be used to perform grouting operations on the fixed section of the prestressed anchor during the permanent fixing operation of the prestressed anchor.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting a side-rotating clamp, when used in recyclable prestressed anchors in waste soil, it provides an auxiliary fixing structure, improving the temporary fixing effect of the prestressed anchor and facilitating its recycling operation. During use, the side-rotating clamp is operated via a control rope, causing it to engage inside the waste soil, increasing the stress-bearing area of ​​the prestressed anchor. During recycling, the control rope is used to reset the side-rotating clamp, allowing the prestressed anchor to be pulled out. In use, a cylindrical hole is drilled in the side wall of the waste soil pit using a drill rod. The conical anchor head is inserted to the bottom of the cylindrical hole, and an elastic rotating shaft is used to create an elastic side-rotating structure for the side-rotating clamp. The control rope... Adjust the opening angle of the side-rotating clamps. When using, loosen the control rope and use the elastic shaft to open the two sets of side-rotating clamps outward, allowing one end of the side-rotating clamp to insert into the interior of the waste soil. At the same time, pull the prestressed anchor to rotate the side-rotating clamps outward, causing one end of the side-rotating clamp to be stuck in the waste soil, increasing the insertion depth of the side-rotating clamps and enhancing their fixing effect, thus completing the temporary fixing operation of the prestressed anchor. During the retrieval operation, pull the control rope to drive one end of the side-rotating clamp to reset, allowing the side-rotating clamps to be re-locked on both sides of the reinforced section. The user can then pull the steel strand to remove the prestressed anchor, completing the prestressed anchor retrieval operation.

[0022] 2. By installing a recycler, when using recyclable prestressed anchors in waste soil, an automatic recycling structure is provided, improving the recycling efficiency of the prestressed anchor. Simultaneously, a side-rotating clamping structure is used for pulling and fixing the steel strand, improving the fixing effect and preventing slippage. During operation, the limiting plate and pull plate of the recycler are respectively passed through one end of the steel strand. The pull plate, in conjunction with the fixing clips, fixes the end of the steel strand. A hydraulic jack reciprocates, driving the pull plate up and down. Each movement of the pull plate pulls out a certain distance of the steel strand. After repeating this operation several times, the entire steel strand is pulled out, completing the recycling operation of the prestressed anchor. When the hydraulic jack drives the pull plate downwards... Because both sets of first and second clamping plates are designed with an inclined structure, the steel strand can pass upward through the two sets of first and second clamping plates. The two sets of first and second clamping plates form a double fixing structure. When the pull plate moves upward, one end of the first and second clamping plates rotates inward in coordination with the movement of the steel strand, so that the first and second clamping plates are clamped and fixed on both sides of the steel strand. When the first and second clamping plates fix the steel strand, one end of the first and second clamping plates abuts against each other, controlling the fixing angle of the first and second clamping plates, avoiding damage to the steel strand by the first and second clamping plates, and achieving a tight clamping and fixing of the steel strand, giving it a prestressed anchor-assisted recycling structure and improving its use effect.

[0023] 3. By setting threaded clamps and tapered heads, when used in recyclable prestressed anchor cables in waste soil, a combined installation structure is provided, optimizing the use of the side-rotating clamps and improving the safety of temporary fixing operations. During use, the threaded clamps can be used to splice and fix the tapered heads to the end of the side-rotating base. After long-term use, the tapered heads are easy to replace. Secondly, the inner side of the arc-shaped groove is provided with several sets of arc-shaped locking teeth. The arc-shaped groove and the arc-shaped locking teeth can improve the fixing effect of the first and second clamping plates, increase the friction between the first and second clamping plates and the steel strand, optimize the use of the first and second clamping plates, and make the fixing operation of the steel strand better.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0033] like Figure 1-6 As shown, a recyclable prestressed anchor cable applied in waste soil includes a conical anchor head 1, a reinforcing section 2, and several sets of steel strands 5. The conical anchor head 1 is fixedly installed on the lower outer surface of the reinforcing section 2, and the several sets of steel strands 5 are all fixedly installed on the upper end of the reinforcing section 2. A protective sleeve 13 is sleeved between the steel strands 5 and the reinforcing section 2. Side-rotating clamps 3 are movably installed on both sides of the reinforcing section 2. The side-rotating clamps 3 and the reinforcing section 2 are movably connected by an elastic rotating shaft 14. The side-rotating clamps 3 have an overall conical structure, and the two sets of side-rotating clamps 3 are symmetrically arranged. A control rope 12 is connected to the upper end of the side-rotating clamps 3. A recycler 10 for recycling operations is installed on the upper part of the several sets of steel strands 5. The recycler 10 includes a limiting top plate 7 and a pull plate 9. The pull plate 9 is movably installed on the upper part of the limiting top plate 7, and the pull plate 9 and the limiting top plate 7 are driven by two hydraulic jacks 8.

[0034] The inner side of the pull-out plate 9 is spliced ​​with an upper chuck 18 for connecting the steel strand 5, and the inner side of the limiting top plate 7 is spliced ​​with a lower chuck 17 for connecting the steel strand 5. The inner sides of the upper chuck 18 and the lower chuck 17 are provided with several sets of round holes. When the prestressed anchor is recycled, the limiting top plate 7 and the pull-out plate 9 of the recycling device 10 are respectively passed through one end of the steel strand 5. The pull-out plate 9 is used in conjunction with the fixing clip 20 to fix the end of the steel strand 5. The hydraulic push rod 8 drives the pull-out plate 9 to move up and down. Each time the pull-out plate 9 moves, the steel strand 5 can be pulled out a certain distance. After repeating the operation several times, the steel strand 5 can be pulled out as a whole, thus completing the recycling operation of the prestressed anchor.

[0035] The upper chuck 18 has a fixing clip 20 in the round hole for fixing the steel strand 5, and the lower chuck 17 has a roller in the round hole. Support brackets 19 are fixedly installed on both outer surfaces of the limiting top plate 7. The support brackets 19, together with the use of bolts, play an auxiliary role in fixing the installation of the recycler 10. The fixing clips 20 can clamp and fix both sides of the steel strand 5, making it easy to pull out the steel strand 5.

[0036] The fixing clip 20 includes two sets of first clip plates 21 and two sets of second clip plates 22. Both sets of first clip plates 21 and two sets of second clip plates 22 are inclined and symmetrical to each other. The steel strand 5 and the reinforcing section 2 are fixed together by fixing clips 15. The reinforcing section 2 is movably installed with guide wheels 16 that work with the control rope 12. When the hydraulic jack 8 drives the pull plate 9 to move down, the steel strand 5 can pass upward through the two sets of first clip plates 21 and two sets of second clip plates 22 because the two sets of first clip plates 21 and two sets of second clip plates 22 are inclined. The two sets of first clip plates 21 and two sets of second clip plates 22 constitute a double fixing structure.

[0037] The first chuck 21 and the second chuck 22 are both provided with a docking shaft 24 in the middle. The first chuck 21, the second chuck 22 and the upper chuck 18 are all movably connected by the docking shaft 24. By using the docking shaft 24, the first chuck 21 and the second chuck 22 can be in a side-rotating structure inside the upper chuck 18.

[0038] A tension spring 23 is movably installed at one end of the first clamping plate 21 and the second clamping plate 22. One end of the first clamping plate 21 and the second clamping plate 22 is elastically connected to the side wall of the pull-out plate 9 through the tension spring 23. The tension spring 23 allows the first clamping plate 21 and the second clamping plate 22 to rotate actively to one end. During the use of the pull-out plate 9, the first clamping plate 21 and the second clamping plate 22 can be tightly attached to both sides of the steel strand 5. When the pull-out plate 9 moves upward, one end of the first clamping plate 21 and the second clamping plate 22 rotates inward in coordination with the movement of the steel strand 5, so that the first clamping plate 21 and the second clamping plate 22 are clamped and fixed to both sides of the steel strand 5. When the first clamping plate 21 and the second clamping plate 22 fix the steel strand 5, one end of the first clamping plate 21 and the second clamping plate 22 abuts against each other, controlling the fixing angle of the first clamping plate 21 and the second clamping plate 22 and preventing the first clamping plate 21 and the second clamping plate 22 from damaging the steel strand 5.

[0039] The first card plate 21 and the second card plate 22 are each provided with an arc-shaped groove 25 on the other side. The inner side of the arc-shaped groove 25 is provided with several sets of arc-shaped teeth. The arc-shaped groove 25, together with the arc-shaped teeth, can improve the fixing effect of the first card plate 21 and the second card plate 22 and increase the friction between the first card plate 21, the second card plate 22 and the steel strand 5.

[0040] The side-rotating clamp 3 includes a side-rotating base 27 and a conical head 29. The conical head 29 is spliced ​​and installed at one end of the side-rotating base 27. The side-rotating base 27 and the conical head 29 are spliced ​​and fixed together by a threaded clamp 28. A rotating cap 26 is provided at one end of the side-rotating base 27. The side-rotating clamp 3 is set with an elastic rotating shaft 14, so that the side-rotating clamp 3 has an elastic side-rotating structure. The opening and closing angle of the side-rotating clamp 3 can be adjusted by the control rope 12. When in use, the side-rotating clamp 3 is loosened, so that the two sets of side-rotating clamps 3 open outward. At the same time, the prestressed anchor is pulled, so that the side-rotating clamp 3 rotates outward, so that one end of the side-rotating clamp 3 is stuck in the garbage soil, thereby increasing its fixing effect.

[0041] The outer surface of the steel strand 5 is movably fitted with a second ring 6, and the outer surface of the steel strand 5 is provided with a first ring 4 located below the second ring 6. Both the second ring 6 and the first ring 4 are provided with circular grooves 11. The circular grooves 11 are provided so that when the prestressed anchor is permanently fixed, the fixed section of the prestressed anchor can be grouted using the circular grooves 11.

[0042] This recyclable prestressed anchor cable, applied to waste soil, features a side-rotating clamp 3. This provides an auxiliary fixing structure, enhancing the temporary fixing effect of the prestressed anchor and facilitating its recycling. During use, the side-rotating clamp 3 is operated via a control rope 12, causing it to engage within the waste soil, increasing the stress-bearing area of ​​the prestressed anchor. During recycling, the control rope 12 is used to reset the side-rotating clamp 3, allowing the prestressed anchor to be pulled out. In use, a cylindrical hole is drilled into the side wall of the waste soil pit using a drill rod, and the conical anchor head 1 is inserted to the bottom of the cylindrical hole. The elastic rotating shaft 14 is used to provide the side-rotating clamp 3 with an elastic side-rotating structure. The opening and closing angle of the side-rotating clamp 3 is adjusted by the control rope 12. When in use, the control rope 12 is released, and the elastic rotating shaft 14 is used to make the two sets of side-rotating clamps 3 open outward, so that one end of the side-rotating clamp 3 is inserted into the interior of the garbage soil. At the same time, the prestressed anchor is pulled, so that the side-rotating clamp 3 rotates outward, and one end of the side-rotating clamp 3 is stuck in the garbage soil, increasing the insertion depth of the side-rotating clamp 3 and increasing its fixing effect, thus completing the temporary fixing operation of the prestressed anchor. When it is retracted, the control rope 12 is pulled, so that the control rope 12 drives one end of the side-rotating clamp 3 to reset, so that the side-rotating clamp 3 is re-clamped on both sides of the reinforced section 2. The user can pull out the prestressed anchor by pulling the steel strand 5 to complete the prestressed anchor retrieval operation.

[0043] By setting up the recycler 10, when the prestressed anchor cable is used in the waste soil, it has an automatic recycling structure, which improves the recycling efficiency of the prestressed anchor. At the same time, a side-rotating clamping structure is used to pull and fix the steel strand 5, which improves the fixing effect of the steel strand 5 and avoids slippage. During operation, the limiting top plate 7 and the pull plate 9 of the recycler 10 are respectively passed through one end of the steel strand 5. The pull plate 9 is used in conjunction with the fixing clip 20 to fix the end of the steel strand 5. The hydraulic jack 8 drives the pull plate 9 to move up and down. Each time the pull plate 9 moves, the steel strand 5 is pulled out a certain distance. After repeating the operation several times, the steel strand 5 can be pulled out as a whole, thus completing the recycling operation of the prestressed anchor. When the hydraulic jack 8 drives the pull plate 9 to move down, because of the two sets of first clamping plates 21 and two The second set of clamping plates 22 all adopt an inclined structure design, which allows the steel strand 5 to pass upward through the two sets of first clamping plates 21 and the two sets of second clamping plates 22. The two sets of first clamping plates 21 and the two sets of second clamping plates 22 form a double fixing structure. When the pull plate 9 moves upward, one end of the first clamping plate 21 and the second clamping plate 22 rotates inward in coordination with the movement of the steel strand 5, so that the first clamping plate 21 and the second clamping plate 22 are clamped and fixed on both sides of the steel strand 5. When the first clamping plate 21 and the second clamping plate 22 fix the steel strand 5, one end of the first clamping plate 21 and the second clamping plate 22 abuts against each other, which controls the fixing angle of the first clamping plate 21 and the second clamping plate 22, avoids the first clamping plate 21 and the second clamping plate 22 from damaging the steel strand 5, and achieves clamping and fixing of the steel strand 5, giving it a prestressed anchor-assisted recycling structure and improving its use effect.

[0044] By setting the threaded clamp 28 and the conical head 29, when used in recyclable prestressed anchor cables in waste soil, a combined installation structure is provided, optimizing the use of the side-rotating clamp 3 and improving the safety of its temporary fixing operation. In use, the threaded clamp 28 can be used to splice and fix the conical head 29 to the end of the side-rotating base 27, making it convenient to replace the conical head 29 after long-term use. Secondly, the inner side of the arc-shaped groove 25 is provided with several sets of arc-shaped locking teeth. The arc-shaped groove 25, together with the arc-shaped locking teeth, can improve the fixing effect of the first clamping plate 21 and the second clamping plate 22, increase the friction between the first clamping plate 21, the second clamping plate 22 and the steel strand 5, optimize the use of the first clamping plate 21 and the second clamping plate 22, and make it better to use the fixing operation of the steel strand 5.
