Description

Technical Field

[0001] This utility model relates to the field of slope reinforcement technology, specifically to a steel pipe pile reinforcement device for railway slopes. Background Technology

[0002] Railway slopes are core infrastructure components ensuring railway subgrade stability and operational safety. Railway slopes operate in a complex environment, constantly subjected to natural climatic influences such as rainwater infiltration and erosion, wet-dry cycles, and wind erosion. They also bear the high-frequency vibration loads generated by passing trains, making them highly susceptible to soil loosening, cracking, slippage, and collapse. This can lead to subgrade settlement and track deformation, and in severe cases, directly threaten railway safety, causing line shutdowns and economic losses. Therefore, reliable and long-term reinforcement and support of railway slopes is crucial for routine railway operation and disaster prevention.

[0003] Currently, steel pipe pile support structures have become the mainstream technology for railway slope reinforcement and treatment due to their high overall strength, fast construction speed, and strong site adaptability. Existing steel pipe piles, through the single support of the pile body, can basically meet the foundation support needs of conventional slopes. However, long-term engineering applications have revealed that the lack of auxiliary reinforcement structures results in poor overall reinforcement bearing capacity and resistance to loosening.

[0004] Therefore, this utility model provides a steel pipe pile reinforcement device for railway slopes to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a steel pipe pile reinforcement device for railway slopes, which effectively solves the problem that the existing steel pipe piles are supported by a single pile body and lack auxiliary reinforcement structures, resulting in poor overall reinforcement bearing capacity and anti-loosening performance.

[0006] The technical solution provided by this utility model is a steel pipe pile reinforcement device for railway slope, comprising a pile body, on which a fixing plate is detachably connected, the fixing plate being composed of two symmetrically arranged fixing plates, the two fixing plates being fixed by bolts;

[0007] Both fixed plates are fixedly connected to fixed anchor rods at their lower ends. Several rotating clamping plates are hinged to the side walls of the fixed anchor rods. A pressing block is fixedly connected to the lower end of each rotating clamping plate. A threaded rod is threaded inside the fixed anchor rod. A pushing member for pushing the pressing block is fixedly connected to the threaded rod. The pushing member has an isosceles trapezoidal cross-section.

[0008] Preferably, the hinge shaft of the rotating clamping plate is located on the upper part of the rotating clamping plate, and the distance from the hinge shaft to the top of the clamping plate is one-third of the total height of the clamping plate.

[0009] Preferably, a hexagonal screwing block is fixed at the upper end of the threaded rod.

[0010] Preferably, two opposing reinforcing plates are fixedly installed on the pile body, and the same end of the two fixed plates is fixed to the same reinforcing plate by bolts.

[0011] Preferably, a semi-circular fixing bushing is fixedly connected to each of the two reinforcing plates on the side that is close to each other. The fixing bushing is used to fit the pile body, and a rubber compression pad is provided inside the fixing bushing.

[0012] Preferably, an auxiliary clamping component is slidably connected inside the fixed bushing. A clamping rubber block is fixedly connected to one end of the auxiliary clamping component near the pile body, and a top block is fixedly connected to the other end of the auxiliary clamping component. A clamping bushing for pushing the top block is fixedly installed on one side of each of the two fixed plates that are close to each other.

[0013] Preferably, the end of the compression rubber block near the pile body has multiple longitudinally arranged grooves.

[0014] Preferably, two extended pressing blocks are symmetrically arranged at the upper and lower ends of the pressing rubber block, and the cross-section of the extended pressing blocks is triangular.

[0015] Preferably, a reinforcing rib is connected between the clamping bushing and the fixing plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model solves the problem that existing steel pipe piles rely on a single pile body for support, lacking auxiliary reinforcement structures, resulting in poor overall reinforcement bearing capacity and anti-loosening performance. This is achieved by setting up a pile body, a fixing plate, a fixing anchor rod, a rotating clamping plate, a pressing block, a threaded rod, and a pushing component, thereby realizing auxiliary reinforcement through anchor rods.

[0018] The fixing plate is fixed to the pile body by adding a fixed bushing, rubber pressure pad, auxiliary pressure component, pressure rubber block, top block, pressure bushing and extension pressure block.

[0019] This utility model optimizes the structure of the fixing device and adds auxiliary fixing anchors in conjunction with an adaptive clamping structure, which effectively improves the fixing firmness of steel pipe piles and the overall slope reinforcement effect, thereby meeting the long-term stability reinforcement and protection needs of railway slopes.

[0034] Refer to the instruction manual appendix Figure 1-7 A steel pipe pile reinforcement device for railway slope includes a pile body 1, characterized in that a fixing plate is detachably connected to the pile body 1, the fixing plate is composed of two symmetrically arranged fixing plates 2, and the two fixing plates 2 are fixed by bolts.

[0035] Both fixed plates 2 are fixedly connected to fixed anchor rods 3 at their lower ends. Several rotating clamping plates 4 are hinged to the side wall of the fixed anchor rods 3. The lower end of the rotating clamping plates 4 is fixedly connected to a pressing block 5. The fixed anchor rods 3 are internally threaded with threaded rods 6. A pushing member 7 for pushing the pressing block 5 is fixedly connected to the threaded rod 6. The pushing member 7 has an isosceles trapezoidal cross section.

[0036] A hexagonal screw block 8 is fixed at the upper end of the threaded rod 6.

[0037] When in use, the pile body 1 is inserted into the preset position, the fixed anchor rod 3 is inserted into the ground, the screwing block 8 is rotated, the threaded rod 6 rotates and moves downward inside the fixed anchor rod 3, the pushing part 7 moves downward synchronously, the inclined surface below the pushing part 7 contacts the pressing block 5, and then the pushing part 7 continues to move downward to push the pressing block 5 to move away from the threaded rod 6. The pressing block 5 simultaneously pushes the lower end of the rotating clamping plate 4 to swing and open away from the threaded rod 6, thereby fixing the fixed anchor rod 3 in the current position, thus improving the fixing effect.

[0038] The hinge shaft of the rotating pressure plate 4 is located on the upper part of the rotating pressure plate 4, and the distance from the hinge shaft to the top of the pressure plate is one-third of the total height of the pressure plate.

[0039] After use, the threaded rod 6 is rotated in the opposite direction, and the threaded rod 6 moves upward. The pushing part 7 moves upward synchronously, so that the pushing part 7 and the upper end of the rotating clamping plate 4 come into contact. Then, the upper end of the rotating clamping plate 4 is pushed to swing away from the threaded rod 6, so that the rotating clamping plate 4 remains in a vertical state, which facilitates the insertion and removal of the anchor rod 3.

[0040] Two opposing reinforcing plates 9 are fixedly installed on the pile body 1. The same end of the two fixing plates 2 is fixed to the same reinforcing plate 9 by bolts, which is used to reinforce the fixing plates 2.

[0041] Two reinforcing plates 9 are fixedly connected to semi-circular fixed bushings 10 on their sides that are close to each other. The reinforcing plates 9 are provided with arc-shaped grooves on their sides that are close to each other for fitting with the outer wall of the pile body 1. The fixed bushings 10 are used to fit with the pile body 1. A rubber compression pad 11 is provided inside the fixed bushings 10.

[0042] With this setup, during installation, two reinforcing plates 9 are installed on both sides of the pile body 1, the fixing bushing 10 is fitted with the pile body 1, and after being fixed with bolts, the rubber pressure pad 11 is pressed onto the pile body 1, thereby fixing the reinforcing plates 9 in the current position.

[0043] An auxiliary clamping component 12 is slidably connected inside the fixed bushing 10. A clamping rubber block 13 is fixedly connected to one end of the auxiliary clamping component 12 near the pile body 1, and a top block 14 is fixedly connected to the other end of the auxiliary clamping component 12. A clamping bushing 15 for pushing the top block 14 is fixedly installed on one side of the two fixed plates 2 that are close to each other.

[0044] Two extended pressing blocks 17 are symmetrically arranged at the upper and lower ends of the pressing rubber block 13, and the cross-section of the extended pressing block 17 is triangular.

[0045] In use, two reinforcing plates 9 are installed on both sides of the pile body 1, and two fixing plates 2 are placed on the reinforcing plates 9. Then, the fixing plates 2 are fixed to the reinforcing plates 9 with bolts. After the clamping bushing 15 and the top block 14 come into contact, the top block 14 pushes the auxiliary clamping member 12 towards the pile body 1. The clamping rubber block 13 clamps the outer wall of the pile body 1, fixing the reinforcing plate 9 to the pile body 1. When the auxiliary clamping member 12 is pushed towards the pile body 1, the extension clamping block 17 is simultaneously squeezed and deformed towards the pile body 1. After the extension clamping block 17 is squeezed and deformed, the inclined surface of the extension clamping block 17 fits against the outer side of the pile body 1, further fixing the reinforcing plate 9.

[0046] Multiple longitudinally arranged grooves 16 are provided at one end of the compression rubber block 13 near the pile body 1 to increase the friction of the compression rubber block 13.

[0047] A reinforcing rib plate 18 is connected between the clamping bushing 15 and the fixing plate 2 to reinforce the clamping bushing 15.

[0048] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
