Description

Technical Field

[0001] This invention belongs to the technical field of slope reinforcement near railway lines, specifically, it relates to a rapid reinforcement device for steel pipe piles on slopes near railway lines. Background Technology

[0002] When a newly constructed railway line is adjacent to an existing highway, the mountainous terrain often causes the excavation surface of the railway bridge's substructure pile foundations and abutments to encroach on the highway slope. This impacts the stability of the highway slope and the safety of traffic during the excavation process. Traditionally, concrete piles with a diameter of 1.5m to 1.8m are used for temporary slope protection. However, this requires large-scale pile foundation construction equipment and occupies at least half of the road, resulting in a large land area and a long construction period. Furthermore, large-scale pile foundation construction causes irreversible damage to the existing road surface, disrupting highway transportation during periods of high traffic volume. Therefore, the conditions for constructing large-diameter concrete retaining piles that require road occupancy are not feasible. Therefore, there is an urgent need for a rapid reinforcement device for steel pipe piles on slopes adjacent to railway lines. This device can comprehensively reinforce the soil surrounding the slope, effectively improving the overall stability of the slope, significantly reducing on-site preparation, minimizing road occupancy, reducing the impact of construction on the surrounding environment, and improving reinforcement efficiency. Summary of the Invention

[0003] This invention provides a rapid reinforcement device for steel pipe piles on slopes near railway lines, which is used to reinforce the soil around the slopes near railway lines as a whole, effectively improving the overall stability of the slopes, greatly reducing the preparation conditions at the construction site, reducing road occupation, reducing the impact of construction on the surrounding environment, and improving the efficiency of reinforcement.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rapid reinforcement device for steel pipe piles near railway line slopes includes a vertical drive rail mounted on a work vehicle. A traveling mechanism capable of vertical movement is mounted on the vertical drive rail. The traveling mechanism is connected to an assembly base via a lateral telescopic arm. A slurry distribution mechanism, a drill position adjustment mechanism, and a drilling transmission mechanism are sequentially arranged vertically downwards on the assembly base. A drive mechanism is installed between the assembly base and the drilling transmission mechanism. The drilling transmission mechanism has multiple output units, and a clamping and circumferential cutting mechanism is mounted on each output unit. The upper end of the steel pipe pile is clamped within the clamping and circumferential cutting mechanism.

[0005] Furthermore, the vertical transmission rail includes a vertical rail body fixedly connected to the work vehicle via a fixed seat. A vertical groove is provided at one end of the vertical rail body near the traveling mechanism. The traveling mechanism is slidably connected to the vertical rail body via the vertical groove. Vertical racks are fixed on both sides of the vertical rail body, and the traveling mechanism is connected to the two vertical racks in a transmission manner.

[0006] Furthermore, the traveling mechanism includes two drive motors detachably mounted on both sides of the mounting base, and a drive gear is coaxially mounted on the output shaft of each drive motor. The drive gear is connected to a corresponding vertical rack and pinion. A sliding block is constructed on the mounting base, and the sliding block is slidably mounted in a vertical groove.

[0007] Furthermore, the drill position adjustment mechanism includes a disc-shaped seat installed at the lower end of the slurry distribution mechanism, and multiple radial adjustment units are detachably installed on the disc-shaped seat at circumferential intervals. Each clamping and circumferential cutting mechanism is connected to the radial adjustment unit via a corresponding output unit.

[0008] Furthermore, the radial adjustment unit includes a radial arm with one end connected to a disc-shaped seat, an adjusting screw threaded onto the radial arm, the adjusting screw extending radially along the disc-shaped seat, and a vertical guide tube slidably mounted on the radial arm. The vertical guide tube is rotatably connected to one end of the adjusting screw, and the vertical guide tube is rotatably connected to a corresponding output unit. The vertical guide tube is connected to the steel pipe pile via the output unit.

[0009] Furthermore, the drilling transmission mechanism includes a drive gear that is driven to rotate and is connected to the drive mechanism. The drive gear is also connected to each output unit. Each output unit includes a vertical sleeve, and a driven gear is coaxially mounted on the outside of the vertical sleeve. The drive gear meshes with the driven gear. The lower end of the vertical sleeve is connected to a clamping ring cutting mechanism, and the upper end of the vertical sleeve is rotatably connected to the corresponding vertical guide tube.

[0010] Furthermore, the drive mechanism is connected to the vertical shaft, the vertical shaft is rotatably connected to the mounting base, and the lower end of the vertical shaft is coaxially connected to the drive gear. The drive gear includes an external gear ring and a central seat coaxially arranged. The central seat is coaxially connected to the vertical shaft, and the external gear ring is detachably connected to the outside of the central seat.

[0011] Furthermore, the clamping and circumferential cutting mechanism includes a columnar seat fixed to the lower end of the output unit, an assembly opening is provided at the center of the columnar seat, the upper end of the steel pipe pile is assembled in the assembly opening, and clamping units and circumferential cutting units are assembled at intervals along the vertical direction on the columnar seat.

[0012] Furthermore, the slurry distribution mechanism includes a distribution body whose upper and lower ends are connected one-to-one with the assembly base and the drilling position adjustment mechanism. A distribution cavity is constructed in the distribution body, and a slurry inlet joint and multiple slurry outlet hoses are constructed on the distribution body. Each of the slurry outlet hoses is connected to the corresponding steel pipe pile.

[0013] Furthermore, the steel pipe pile includes a vertical pile body, in which a grouting channel is formed, and multiple grouting holes are spaced apart on the peripheral wall of the vertical pile body. Drilling blades extending spirally along the axis are constructed on the outer peripheral wall of the vertical pile body.

[0014] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: The lateral telescopic arm extends laterally along the road. Before drilling, multiple steel pipe piles are assembled onto various clamping and circumferential cutting mechanisms. The clamping and circumferential cutting mechanisms are controlled to switch to a clamping state, clamping the corresponding steel pipe piles. Then, by controlling the movement of the lateral telescopic arm, it drives the mounting base and other components on the mounting base to move towards the area to be drilled on the slope. When it reaches above the predetermined area, the drive mechanism is controlled to move, simultaneously controlling the traveling mechanism to move downwards on the vertical transmission rail. The drilling transmission mechanism is controlled by the drive mechanism to rotate, thereby driving the steel pipe piles to drill into the slope soil. Then, pressurized concrete slurry is injected into each steel pipe pile through the slurry distribution mechanism, consolidating the area of ​​the slope where the steel pipe piles are inserted. Afterwards, the clamping and circumferential cutting mechanisms are released from the upper end of the steel pipe piles. Next, the clamping and circumferential cutting mechanisms are controlled to switch to a cutting mode, and the drive mechanism is controlled to cut off the portion of the steel pipe pile above ground level. This invention adjusts the spacing of multiple steel pipe piles connected to the drilling transmission mechanism by adjusting the drilling position adjustment mechanism and replacing corresponding components, thereby effectively reinforcing the slope and preventing damage to the slope caused by excessively small spacing between steel pipe piles during synchronous drilling, such as large cracks or collapses. By introducing high-strength steel pipe piles and grouting materials, this invention overcomes the shortcomings of traditional reinforcement methods. The steel pipe piles themselves have higher strength and stiffness, and the surrounding soil is consolidated as a whole, effectively improving the overall stability of the slope. The steel pipe pile grouting reinforcement method combines precast steel pipe piles with grouting, resulting in a short consolidation time. Excavation can begin the day after reinforcement, significantly shortening the construction cycle and greatly reducing the impact on existing road transport. This invention is particularly suitable for highway subgrades filled with sandy gravel and pebbly soil. It features good grout penetration and diffusion, effectively consolidating with the grout, resulting in good overall integrity and a certain degree of seismic resistance. It can better adapt to the impact of vehicle movement loads, preventing slope instability. In summary, this invention can comprehensively reinforce the soil surrounding slopes near railway lines, effectively improving the overall stability of the slope. It can significantly reduce on-site preparation conditions, minimize road occupancy, reduce the impact of construction on the surrounding environment, and improve reinforcement efficiency.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0019] This invention discloses a rapid reinforcement device for steel pipe piles on slopes adjacent to railway lines, such as... Figures 1-18As shown, the system includes a vertical drive rail 100, a traveling mechanism 200, a horizontal telescopic arm 300, a mounting base 400, a drive mechanism 500, a slurry distribution mechanism 1000, a drill position adjustment mechanism 800, and a drilling transmission mechanism 700. The vertical drive rail 100 is mounted on the work vehicle, the traveling mechanism 200 is mounted on the vertical drive rail 100 and can travel vertically on the vertical drive rail 100, and the two ends of the horizontal telescopic arm 300 are connected to the traveling mechanism 200 and the mounting base 400, respectively. The slurry distribution mechanism 1000, the drill position adjustment mechanism 800, and the drilling transmission mechanism 700 are arranged vertically downwards on the mounting base 400, and the drive mechanism 500 is installed between the mounting base 400 and the drilling transmission mechanism 700. The drilling transmission mechanism 700 has multiple output units, each equipped with a clamping and circumferential cutting mechanism 600. The upper end of the steel pipe pile 900 is clamped within the clamping and circumferential cutting mechanism 600. The lateral telescopic arm 300 of this invention is generally a hydraulic cylinder. The working principle and advantages of this invention are as follows: The lateral telescopic arm 300 extends laterally along the road. Before drilling, multiple steel pipe piles 900 are respectively assembled onto each clamping and circumferential cutting mechanism 600. The clamping and circumferential cutting mechanism 600 is controlled to switch to a clamping state, clamping the corresponding steel pipe pile 900. Then, by controlling the movement of the lateral telescopic arm 300, it drives the mounting base 400 and other components on the mounting base 400 to move towards the area to be drilled on the slope. When it reaches above the predetermined area, the drive mechanism 500 is controlled to move, and simultaneously the traveling mechanism 200 is controlled to move downwards on the vertical transmission rail 100. The drilling transmission mechanism 700... The 0 is controlled by the drive mechanism 500 to rotate all the output units, thereby driving the steel pipe pile 900 to drill into the slope, so that the steel pipe pile 900 drills into the soil of the slope; then the pressurized concrete grout is injected into each steel pipe pile 900 through the grout distribution mechanism 1000, so that the area where the steel pipe pile 900 is inserted into the slope is consolidated; then, the clamping ring cutting mechanism 600 is released from the clamping of the upper end of the steel pipe pile 900, and then the clamping ring cutting mechanism 600 is controlled to switch to the cutting mode, and the drive mechanism 500 is controlled to move, so that the clamping ring cutting mechanism 600 cuts off the part of the steel pipe pile 900 above the ground. This invention allows for adjustment of the spacing between multiple steel pipe piles 900 connected to the drilling transmission mechanism 700 by adjusting the drilling position adjustment mechanism 800 and simultaneously replacing corresponding components in the drilling transmission mechanism 700. This effectively reinforces the slope while preventing damage to the slope caused by excessively small spacing between the steel pipe piles 900 during synchronous drilling, such as large cracks or collapses. By introducing high-strength steel pipe piles 900 and grouting materials, this invention overcomes the shortcomings of traditional reinforcement methods. Not only do the steel pipe piles 900 themselves have higher strength and rigidity, but they also provide overall consolidation of the surrounding soil, effectively improving the overall stability of the slope.The 900mm steel pipe pile grouting reinforcement method combines prefabricated 900mm steel pipe piles with grouting, resulting in a short consolidation time. Excavation of the foundation pit can begin the day after reinforcement, significantly shortening the construction cycle and greatly reducing the impact on existing highway transportation. This invention is particularly suitable for highway subgrades filled with sandy gravel soil. The grouting has good penetration and diffusion effects, effectively consolidating with the grout, resulting in good integrity and certain seismic performance. It can better adapt to the impact of vehicle moving loads, preventing slope instability. In summary, this invention can comprehensively reinforce the soil surrounding slopes near railway lines, effectively improving the overall stability of the slope, greatly reducing on-site preparation conditions, minimizing road occupancy, reducing the impact of construction on the surrounding environment, and improving reinforcement efficiency.

[0020] As a preferred embodiment of the present invention, such as Figure 2 As shown, the vertical drive rail 100 includes a vertical rail body 101. A fixed seat 102 is constructed at one end of the vertical rail body 101, and the fixed seat 102 is fixedly connected to the work vehicle. A vertical groove 105 is formed at the end of the vertical rail body 101 near the traveling mechanism 200. The traveling mechanism 200 is slidably connected to the vertical rail body 101 through the vertical groove 105. Vertical racks 103 are fixed on both sides of the vertical rail body 101. Side flanges 104 are formed on both sides of each vertical rack 103. Each side flange 104 extends vertically from the lower end of the vertical rail body 101 to the upper end of the vertical rail body 101. The traveling mechanism 200 is drively connected to the two vertical racks 103. Specifically, as shown... Figure 3 As shown, the traveling mechanism 200 includes a mounting base 201 and two drive motors 203. These two drive motors 203 are detachably mounted on both sides of the mounting base 201. Drive gears 204 are coaxially mounted on the output shafts of the drive motors 203, and the drive gears 204 are connected to a corresponding vertical rack 103. A sliding block 202 is constructed on the mounting base 201, and the sliding block 202 is slidably fitted within a vertical groove 105. This embodiment controls the synchronous operation of the two drive motors 203. To ensure synchronous operation of the two drive motors 203, a dedicated synchronous controller is used, employing integrated motor drive chips or controllers, such as TI's DRV series or ST's L6206. These chips have built-in synchronization logic, which can copy one control signal to the drive channels of the two drive motors 203, ensuring no signal delay difference. Driven by the drive gear 204 and the vertical rack 103, the two drive the mounting base 201 to move in the vertical direction. The mounting base 201 drives the assembly base 400 to move through the horizontal telescopic arm 300, so that the assembly base 400 indirectly drives the steel pipe pile 900 to anchor towards the slope, so as to facilitate subsequent grouting reinforcement.

[0021] As a preferred embodiment of the present invention, such as Figures 5-8As shown, the drill position adjustment mechanism 800 includes a disc-shaped seat 801 and multiple radial adjustment units. The disc-shaped seat 801 is detachably installed at the lower end of the slurry distribution mechanism 1000. The multiple radial adjustment units are arranged circumferentially around the disc-shaped seat 801, and one end of each radial adjustment unit is detachably connected to the disc-shaped seat 801. Each clamping and circumferential cutting mechanism 600 is connected to the radial adjustment unit via a corresponding output unit. The specific structure of the radial adjustment unit in this embodiment is as follows: the radial adjustment unit includes a radial arm 803, a vertical guide tube 806, and an adjusting screw 809. The radial arm 803 extends radially outward along the disc-shaped seat 801. A transition seat 804 is constructed at one end of the radial arm 803. Annular limiting grooves 802 are respectively opened at the upper and lower ends of the disc-shaped seat 801. The axis of the annular limiting groove 802 coincides with the axis of the disc-shaped seat 801. The transition seat 804 is fastened to the edge of the disc-shaped seat 801, and the upper and lower ends of the transition seat 804 are respectively fastened in the corresponding annular limiting grooves 802. Multiple locking bolts are threaded onto the transition seat 804. The ends of the locking bolts are screwed onto the disc-shaped seat 801, thereby fixing the transition seat 804 and the disc-shaped seat 801. A strip-shaped assembly hole 805 is provided on the radial arm 803, extending along the length of the radial arm 803. An assembly block 807 is installed on the vertical guide tube 806, and the assembly block 807 is slidably assembled in the strip-shaped assembly hole 805. In this embodiment, the adjusting screw 809 extends radially along the disc-shaped seat 801. The end of the assembly block 807 away from the disc-shaped seat 801 is rotatably connected to the end of the adjusting screw 809 near the disc-shaped seat 801. The other end of the adjusting screw 809 passes through the strip-shaped assembly hole 805 and exits the radial arm 803. An operating handwheel 810 is installed at this end of the adjusting screw 809. The adjusting screw 809 is threadedly connected to the radial arm 803. The lower end of the vertical guide tube 806 is rotatably connected to the upper end of the corresponding output unit, and the vertical guide tube 806 is connected to the steel pipe pile 900 through the output unit. The working principle and advantages of this embodiment are as follows: When it is necessary to adjust the distance between the steel pipe piles 900 that are synchronously anchored downwards, one or more adjusting screws 809 are controlled to rotate, so that the adjusting screws 809 drive the corresponding vertical guide tube 806 to move along the length direction of the radial arm 803, thereby adjusting the position of the steel pipe pile 900 indirectly connected to the vertical guide tube 806. After the adjustment is completed, the corresponding transmission components of the drilling transmission mechanism 700 are replaced, so that the drilling transmission mechanism 700 can drive the steel pipe pile 900, causing the steel pipe pile 900 to rotate and gradually anchor downwards into the soil of the slope. This embodiment can also adjust the connection position between the radial arm 803 and the disc seat 801 to change the corresponding position between the steel pipe piles 900. Specifically, the locking bolt is loosened, the position of the radial arm 803 is adjusted along the circumference of the disc seat 801, and after the adjustment is completed, the locking bolt is tightened.This embodiment can also combine the two adjustment methods mentioned above to adjust the position of the steel pipe pile 900. The purpose is to effectively reinforce the slope and ensure that after grouting, the concrete slurry can cover the entire anchorage area, so that the anchorage area forms a stable whole, and at the same time avoid the occurrence of slope damage during the anchoring process.

[0022] As a preferred embodiment of the present invention, such as Figure 4 As shown, the drive mechanism 500 includes a power motor 501, a vertical shaft 503, a drive pulley 502, a driven pulley 504, and a transmission belt 505. The power motor 501 is mounted on a mounting base 400, and the vertical shaft 503 is rotatably mounted on the mounting base 400. The vertical shaft 503 passes through the disc-shaped seat 801 of the slurry distribution mechanism 1000 and the drill position adjustment mechanism 800 and is connected to the drilling transmission mechanism 700. The vertical shaft 503 is rotatably connected to the slurry distribution mechanism 1000 and also rotatably connected to the disc-shaped seat 801. In this embodiment, the drive pulley 502 is coaxially mounted on the output shaft of the power motor 501, and the driven pulley 504 is coaxially mounted on the vertical shaft 503. The drive pulley 502 and the driven pulley 504 are connected by the transmission belt 505. The specific structure of the drilling transmission mechanism 700 in this embodiment is as follows: Figures 8-12As shown, the drilling transmission mechanism 700 includes a driving gear and the aforementioned multiple output units. The driving gear is coaxially connected to the vertical shaft 503, and the multiple output units are spaced apart circumferentially along the driving gear, and these output units are drively connected to the driving gear. In this embodiment, the output unit includes a vertical sleeve 705 and a driven gear 706. The driven gear 706 is coaxially mounted outside the vertical sleeve 705. The upper end of the vertical sleeve 705 is fitted and rotatably connected to the lower end of the corresponding vertical guide tube 806, and the vertical sleeve 705 and the vertical guide tube 806 are interconnected. The driving gear meshes with each driven gear 706, and the lower end of the vertical sleeve 705 is connected to the clamping ring cutting mechanism 600. In this embodiment, the driving gear includes a coaxially arranged external gear ring 703 and a central seat 701. The central seat 701 is coaxially connected to the vertical shaft 503, and the external gear ring 703 is detachably connected to the outside of the central seat 701. Specifically, a plurality of first connecting arms 702 are uniformly constructed along the circumference of the center seat 701, and each first connecting arm 702 extends outward along the radial direction of the center seat 701; a plurality of second connecting arms 704 are uniformly constructed along the circumference of the inner circumferential wall of the outer gear ring 703, and each second connecting arm 704 extends inward along the radial direction of the outer gear ring 703, and the second connecting arm 704 is fixed to the corresponding first connecting arm 702 by a plurality of connecting bolts, thereby realizing the connection and fixation between the center seat 701 and the outer gear ring 703. The working principle and advantages of this embodiment are as follows: This embodiment controls the operation of the power motor 501 to drive the vertical shaft 503 to rotate. The vertical shaft 503 drives the drive gear to rotate, which in turn drives each driven gear 706 to rotate. This enables each output unit to drive the steel pipe pile 900 to rotate through the clamping and ring-cutting mechanism 600. Combined with the downward movement of the traveling mechanism 200, this achieves the purpose of downward rotary drilling of the steel pipe pile 900 on the slope. After the steel pipe pile 900 is anchored to the predetermined depth of the slope, grouting is performed. The concrete slurry enters each vertical guide pipe 806 through the slurry distribution mechanism 1000, then passes through the vertical sleeve 705 and the clamping and ring-cutting mechanism 600 before entering the steel pipe pile 900, and finally disperses into the surrounding soil. After completion, the clamping and ring-cutting mechanism 600 releases the steel pipe pile 900 to facilitate switching to the cutting mode, removing the portion of the steel pipe pile 900 exposed above the ground.In this embodiment, during the adjustment of the radial adjustment unit, under normal circumstances, the position of the radial adjustment unit is adjusted along the circumference of the disc seat 801, and the adjustment screw 809 is not adjusted, so there is no need to replace the external gear ring 703. When adjusting the adjustment screw, the adjustment length of all the adjustment screws 809 is the same, which adjusts the radial distance between the driven gear 706 and the driving gear, thereby causing the driven gear 706 and the driving gear to lose their meshing relationship. At this time, it is necessary to replace the corresponding model of the external gear ring 703 so that the external gear ring 703 maintains a meshing relationship with each driven gear 706, ensuring that the driving gear drives all the output units to rotate during the driving process.

[0023] As a preferred embodiment of the present invention, such as Figure 9 , Figure 13 , Figure 14 , Figure 15 , Figure 16As shown, the clamping and circumferential cutting mechanism 600 includes a columnar seat 601, a clamping unit, and a circumferential cutting unit. The upper end of the columnar seat 601 is coaxially and fixedly connected to the lower end of the vertical sleeve 705 of the output unit. An assembly port 602 is provided at the center of the columnar seat 601, passing through both the upper and lower ends of the columnar seat 601. The assembly port 602 is connected to the vertical sleeve 705. The upper end of the steel pipe pile 900 is assembled within the assembly port 602. The clamping unit and the circumferential cutting unit are assembled vertically downwards at intervals on the columnar seat 601. The clamping unit is used to clamp the upper part of the steel pipe pile 900 so that the column base 601 can rotate and anchor the steel pipe pile 900 within the slope as the output unit rotates. The circumferential cutting unit is used to cut off the portion of the steel pipe pile 900 that protrudes from the slope surface. That is, as the column base 601 rotates with the output unit, the circumferential cutting unit rotates along the circumference of the steel pipe pile 900, thereby cutting the upper part of the steel pipe pile 900. The clamping unit in this embodiment includes two first assembly cavities symmetrically opened in the column base 601. The ends of these two first assembly cavities that are close to each other are connected to the assembly opening 602. Each first assembly cavity extends radially along the column base 601. A first annular groove 607 is formed on the outer peripheral wall of the columnar seat 601. The first annular groove 607 coincides with the axis of the columnar seat 601. Two first through holes 609 are formed on the columnar seat 601 at each first assembly cavity, and each first through hole 609 connects the first assembly cavity and the first annular groove 607. A first adapter ring 611 is fitted outside the columnar seat 601 at the first assembly cavity. The first adapter ring 611 is rotatably connected to the columnar seat 601 and is also rotatably connected to the first... Two sealing rings are provided at the outer edge of the annular groove 607. These two sealing rings are fitted over the columnar seat 601. The two sealing rings are located at the upper and lower parts of the contact surface between the first adapter ring 611 and the columnar seat 601, respectively, to prevent hydraulic oil or compressed air from escaping. A first medium connector 612 is constructed on the first adapter ring 611. The first medium connector 612 is connected to the first assembly cavity through the first annular groove 607. A first solenoid valve is installed on the first medium connector 612. In this embodiment, a clamping block 605 is assembled in each first assembly cavity. The clamping block 605 can extend radially into the assembly opening 602 along the columnar seat 601. A first spring 603 is provided at the end of the clamping block 605 away from the assembly opening 602. The two ends of the first spring 603 are connected to the clamping block 605 and the inner wall of the first assembly cavity, respectively, and the first spring 603 extends radially along the columnar seat 601.Hydraulic oil or compressed air enters the first annular groove 607 through the first medium connector 612, and then enters the first assembly cavity through the first through hole 609. This drives the clamping block 605 to gradually extend into the assembly opening 602. At this time, the first spring 603 is elastically stretched and stores energy, so that the clamping block 605 clamps onto the steel pipe pile 900, so that the steel pipe pile 900 can be driven to perform rotary drilling operations during the rotation of the column base 601. After the anchoring of the steel pipe pile 900 is completed, the pressure in the first assembly cavity is released. Under the action of the first spring 603, the clamping block 605 gradually returns to its original position, and the hydraulic oil or compressed air in the first assembly cavity is gradually driven out. The circumferential cutting unit of this embodiment includes two second assembly cavities symmetrically opened in the column base 601. The ends of these two second assembly cavities that are close to each other are connected to the assembly opening 602. Each second assembly cavity extends radially along the column base 601. A second annular groove 608 is formed on the outer peripheral wall of the columnar seat 601. The second annular groove 608 coincides with the axis of the columnar seat 601. Two second through holes 610 are formed on the columnar seat 601 at each second assembly cavity. Each second through hole 610 connects the second assembly cavity and the second annular groove 608. A second adapter ring 613 is fitted outside the columnar seat 601 at the second assembly cavity. The second adapter ring 613 is rotatably connected to the columnar seat 601. Two sealing rings are also fitted between the contact surfaces of the second adapter ring 613 and the columnar seat 601. Their function is the same as that of the sealing ring installed between the first adapter ring 611 and the columnar seat 601. A second medium connector 614 is constructed on the second adapter ring 613. The second medium connector 614 is connected to the second assembly cavity through the second annular groove 608. A second solenoid valve is installed on the second medium connector 614. In this embodiment, a cutting blade 606 is assembled in each second assembly cavity. The cutting blade 606 can extend into the assembly port 602 along the radial direction of the columnar seat 601. A second spring 604 is provided at the end of the cutting blade 606 away from the assembly port 602. The two ends of the second spring 604 are respectively connected to the inner wall of the cutting blade 606 and the second assembly cavity, and the second spring 604 extends radially along the columnar seat 601. Hydraulic oil or compressed air enters the second annular groove 608 through the second medium connector 614, and then enters the second assembly cavity through the second guide hole 610. This drives the cutting blade 606 to gradually extend into the assembly opening 602. At this time, the second spring 604 is elastically stretched and stores energy, causing the cutting blade 606 to contact the outer circumferential surface of the steel pipe pile 900. This allows the cutting blade 606 to perform rotary cutting on the steel pipe pile 900 during the rotation of the column base 601. During the rotary cutting process, the pressure of the hydraulic oil or compressed air is gradually increased to cut off the upper end of the steel pipe pile 900. After the steel pipe pile 900 is cut off, the pressure in the second assembly cavity is released. Under the action of the second spring 604, the cutting blade 606 gradually returns to its original position, and the hydraulic oil or compressed air in the second assembly cavity is gradually driven out.In this embodiment, both the first adapter ring 611 and the second adapter ring 613 are fixed to the vertical guide tube 806 via the adapter plate 615. Thus, during the process of the columnar seat 601 being driven to rotate, the first adapter ring 611 and the second adapter ring 613 remain in a non-rotating state to facilitate the supply of hydraulic oil or compressed air.

[0024] As a preferred embodiment of the present invention, such as Figure 7 , Figure 18 As shown, the slurry distribution mechanism 1000 includes a distribution body 1001, a slurry inlet connector 1002, and multiple slurry outlet hoses 1003. The upper end of the distribution body 1001 is connected and fixed to the mounting base 400, and the lower end of the distribution body 1001 is connected and fixed to the disc-shaped seat 801 of the drill position adjustment mechanism 800. A distribution cavity is constructed within the distribution body 1001, and the slurry inlet connector 1002 is constructed on the outer peripheral wall of the distribution body 1001, communicating with the distribution cavity. The aforementioned plurality of grout outlet hoses 1003 are evenly arranged circumferentially along the distribution body 1001. Each grout outlet hose 1003 communicates with the distribution chamber. A connecting sleeve 1004 is constructed at the end of each grout outlet hose 1003 away from the distribution body 1001, and a connector 808 is constructed at the upper end of each vertical guide tube 806. The connecting sleeve 1004 and the connector 808 are connected together. Preferably, the connecting sleeve 1004 and the connector 808 adopt a quick-connect coupling method, which has the advantages of convenient disassembly and assembly and good sealing performance. Furthermore, the grout outlet hoses 1003, vertical guide tubes 806, vertical sleeves 705, assembly port 602 of column base 601, and steel pipe pile 900 are connected. In this way, concrete grout enters the distribution chamber through the grout inlet connector 1002, is evenly distributed into each grout outlet hose 1003 by the distribution chamber, and then indirectly supplied to the steel pipe pile 900, seeping into the area surrounding the steel pipe pile 900.

[0025] As a preferred embodiment of the present invention, such as Figure 17As shown, the steel pipe pile 900 includes a vertical pile body 901, within which a grouting channel 902 is formed. Multiple grouting holes 903 are spaced apart on the peripheral wall of the vertical pile body 901. A drilling blade 904 is constructed on the outer peripheral wall of the vertical pile body 901, extending spirally along the axis of the vertical pile body 901. The working principle and advantages of this embodiment are as follows: During the process of being driven to rotate and move downwards, the steel pipe pile 900, under the action of the drilling blade 904, gradually excavates downwards and anchors itself within the slope. Furthermore, due to the constraint of the drilling blade 904, after anchoring, the vertical pile body 901 is prevented from relative displacement with the slope soil when subjected to external forces. After the vertical pile 901 is anchored, the concrete grout is pressurized and injected into the grouting channel 902. Then, it seeps into the area around the vertical pile 901 through each grouting hole 903, so that the steel pipe pile 900 and its surroundings are solidified by concrete. Moreover, the concrete grout coming out of the adjacent steel pipe piles 900 is connected to each other and forms a whole. After the concrete solidifies, it forms a complete protective barrier, which improves the reinforcement effect.
