Description

Technical Field

[0001] This utility model relates to the field of anti-landslide pile technology, and in particular to an anti-landslide micropile reinforcement device. Background Technology

[0002] With the development of highway construction and the improvement of its grade, expressways have been continuously extended into mountainous areas, encountering more and more special geological environments. When constructing roadbed slopes in high-altitude areas with severe weathering, loose geology, and thin surface cover, the technology is complex, the pressure to maintain traffic flow is high, and the safety risks are high, and slope collapses often occur. At present, anti-slide piles and retaining walls are still the main methods for landslide prevention and control projects.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220789735U, disclose a landslide-resistant composite micropile reinforcement structure, including a ground pile. At least two threaded rods are spaced apart along the circumference of the ground pile. The threaded rods are inclined and rotatably connected to the ground pile. A movable plate is threaded onto the threaded rod, and an anchor rod is connected to the movable plate. The ground pile has a movable hole for the anchor rod to extend. The structure also includes a control structure for controlling the rotation of the threaded rods. The purpose of this invention is to solve the technical problems existing in the prior art and provide a landslide-resistant composite micropile reinforcement structure that improves the anchoring effect of the ground piles and simplifies the installation and use of anchor rods, thereby improving construction efficiency. However, this invention uses a first bevel gear and a second bevel gear in conjunction with multiple sets of threaded rods to achieve the extension of the anchor rods, resulting in a relatively complex structure that occupies a lot of space and is not conducive to setting multiple sets of anchor rods to increase stability.

[0004] To address the issue that anti-landslide micropiles cannot effectively balance driving efficiency and post-driving stability, existing technologies have found that while designing anti-landslide micropiles with relatively smooth surfaces and straight overall shapes facilitates driving, it also results in insufficient stability. Adding reinforcement devices to anti-landslide micropiles increases stability but reduces driving efficiency. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing anti-slope micropiles are not convenient for balancing pile driving efficiency and post-pile stability, and to propose an anti-slope micropiles reinforcement device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a landslide-resistant micropile reinforcement device, comprising a pile body, a receiving groove, and a reinforcement mechanism. The receiving groove is formed on the surface of the pile body, and the reinforcement mechanism is disposed on the surface of the receiving groove. The reinforcement mechanism includes a screw rod, which is rotatably connected to the inner wall of the receiving groove. A movable plate is threadedly connected to the surface of the screw rod, and a first insertion rod is fixedly connected to the surface of the movable plate. A first insertion hole is formed on the surface of the pile body, and the first insertion rod is inserted into the surface of the first insertion hole. A square plate is slidably connected to the surface of the screw rod, and a connecting rod is rotatably connected to the surface of the square plate. A linkage plate is rotatably connected to the end of the connecting rod away from the square plate, and a second insertion rod is fixedly connected to the surface of the linkage plate. A second insertion hole is formed on the surface of the pile body, and the second insertion rod is inserted into the surface of the second insertion hole. A first spring is sleeved and connected to the surface of the screw rod, with one end of the first spring fixedly connected to the surface of the square plate and the other end of the first spring fixedly connected to the surface of the receiving groove.

[0007] Furthermore, a limiting plate is fixedly connected to the surface of the receiving groove. There are two sets of limiting plates arranged symmetrically, and the limiting plates cooperate with the movable plate.

[0008] Furthermore, a turntable is fixedly connected to the surface of the screw, and the surface of the turntable is provided with anti-slip texture and groove.

[0009] Furthermore, the number of the first insertion rod and the first insertion hole are all four groups and are evenly distributed in a circle. The number of the connecting rod, the linkage plate, the second insertion rod, and the second insertion hole are all four groups and are evenly distributed in a circle. Each group contains multiple second insertion rods and second insertion holes.

[0010] Furthermore, the surface of the receiving groove is provided with an auxiliary mechanism, the auxiliary mechanism including a toothed column, the toothed column being rotatably connected to the inner wall of the receiving groove, a first toothed plate being fixedly connected to the surface of the movable plate, a clearance groove being opened on the surface of the pile body, and a second toothed plate being slidably connected to the surface of the clearance groove.

[0011] Furthermore, the first rack plate is meshed with the surface of the toothed column, and the second rack plate is meshed with the surface of the toothed column. There are two sets of toothed columns, the first rack plate, the relief groove, and the second rack plate, and each set contains two relief grooves and two second rack plates.

[0012] Furthermore, a second spring is fixedly connected to the surface of the rack plate two, and the end of the second spring away from the rack plate two is fixedly connected to the surface of the receiving groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a reinforcement mechanism, after the pile is driven into the ground, the screw is rotated to make the movable plate move downward, causing the first insertion rod to slide out from the first insertion hole and be inserted longitudinally into the ground. At the same time, when the movable plate moves downward to contact the square plate, the square plate is squeezed downward and compresses the first spring. The connecting rod drives the linkage plate to make the second insertion rod slide out from the second insertion hole and be inserted laterally into the ground, thereby reinforcing the pile. When inserting or removing the pile, the first and second insertion rods can be retracted to avoid increasing resistance. When the ground is relatively soft, the turntable can be manually rotated to make the screw rotate. When the ground is relatively hard, the groove can be used in conjunction with a power tool to make the screw rotate. By setting up a reinforcement mechanism, the pile is reinforced by multiple sets of first insertion rods inserted longitudinally into the ground and second insertion rods inserted laterally into the ground. The retraction of the first and second insertion rods when inserting and removing the pile also saves effort, thus effectively improving the stability of the equipment.

[0014] 2. In this utility model, by setting an auxiliary mechanism, when the movable plate moves downward, the first rack plate drives the toothed column, which in turn drives the second rack plate. With the rebound force of the second spring, the second rack plate extends out of the clearance groove, increasing the contact area between the pile and the ground surface and improving the stability of the ground pile. When the movable plate moves upward, the second rack plate retracts and tightens the second spring, reducing the space occupied. By setting an auxiliary mechanism and utilizing the extendable and retractable second rack plate, the stability of the ground pile is increased during use, and the space occupied is reduced when not in use, thus effectively improving the convenience of the equipment.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a landslide-resistant micropile reinforcement device, including a pile body 1, a receiving groove 2 and a reinforcement mechanism 3. The receiving groove 2 is opened on the surface of the pile body 1, and the reinforcement mechanism 3 is disposed on the surface of the receiving groove 2.

[0018] The specific setup and function of its reinforcement mechanism 3 and auxiliary mechanism 4 will be explained below.

[0019] In this embodiment: the reinforcement mechanism 3 includes a screw 301, which is rotatably connected to the inner wall of the receiving groove 2. A movable plate 302 is threadedly connected to the surface of the screw 301. A first insertion rod 303 is fixedly connected to the surface of the movable plate 302. An insertion hole 304 is opened on the surface of the pile body 1. The first insertion rod 303 is inserted into the surface of the first insertion hole 304. A square plate 305 is slidably connected to the surface of the square plate 305. A connecting rod 306 is rotatably connected to the surface of the connecting rod 306 away from the square plate 305. A linkage plate 307 is rotatably connected to the end of the linkage plate 306 away from the square plate 305. A second insertion rod 308 is fixedly connected to the surface of the linkage plate 307. An second insertion hole 309 is opened on the surface of the pile body 1. The second insertion rod 308 is inserted into the surface of the second insertion hole 309. A first spring 310 is sleeved and connected to the surface of the screw 301. One end of the first spring 310 is fixedly connected to the surface of the square plate 305, and the other end of the first spring 310 is fixedly connected to the surface of the receiving groove 2.

[0020] The effects achieved by the above components are as follows: rotating the screw 301 allows the movable plate 302 to move up and down; the insertion rod 303 and insertion hole 304 are provided so that when the movable plate 302 moves downward, the insertion rod 303 slides out of the insertion hole 304 and inserts longitudinally into the ground depth, and also serves to limit the movable plate 302 to prevent it from rotating with the screw 301; the square plate 305, connecting rod 306, linkage plate 307, insertion rod 308, and insertion hole 309 are provided so that when the movable plate 302 moves downward, the insertion rod 308 slides out of the insertion hole 309 and inserts laterally into the ground; the spring 310 is provided so that when the movable plate 302 moves upward, its rebound effect facilitates the reset of the insertion rod 308 and retracts it into the pile body 1, avoiding affecting the pile driving efficiency.

[0021] Specifically, a limiting plate 311 is fixedly connected to the surface of the receiving groove 2. There are two sets of limiting plates 311 arranged symmetrically, and the limiting plates 311 cooperate with the movable plate 302.

[0022] The effect achieved by the above components is as follows: the limiting plate 311 is set to prevent the movable plate 302 from moving upward too much, causing the first insertion rod 303 to disengage from the second insertion rod 308, thereby causing the limiting of the movable plate 302 to fail.

[0023] Specifically, a turntable 312 is fixedly connected to the surface of the screw 301. The surface of the turntable 312 is provided with anti-slip texture 313 and groove 314.

[0024] The effects achieved by the above components are as follows: the turntable 312 is set to facilitate manual rotation of the screw 301; the anti-slip texture 313 is set to increase friction and prevent slippage when rotating the turntable 312; and the groove 314 is set to cooperate with power tools to rotate the screw 301.

[0025] Specifically, there are four sets of plug rod 303 and plug hole 304, which are evenly distributed in a circle. There are four sets of connecting rod 306, linkage plate 307, plug rod 308 and plug hole 309, which are evenly distributed in a circle. Each set of plug rod 308 and plug hole 309 contains multiple plug rods 308 and plug hole 309.

[0026] The effect achieved by the above components is as follows: four sets of insertion rod 1 303 and insertion rod 2 308 are set, and each set of insertion rod 2 308 is set in multiples to increase the stability of pile body 1.

[0027] Specifically, the surface of the receiving groove 2 is provided with an auxiliary mechanism 4, which includes a toothed column 41. The toothed column 41 is rotatably connected to the inner wall of the receiving groove 2. The surface of the movable plate 302 is fixedly connected with a first toothed plate 42. The surface of the pile body 1 is provided with a clearance groove 43, and the surface of the clearance groove 43 is slidably connected with a second toothed plate 44.

[0028] The effects achieved by the above components are as follows: The toothed column 41, the first toothed plate 42, and the second toothed plate 44 are designed so that when the first toothed plate 42 moves downward, the toothed column 41 drives the second toothed plate 44, and with the rebound force of the second spring 45, the second toothed plate 44 extends out of the relief groove 43, increasing the contact area between the pile body 1 and the ground surface and improving the stability of the ground pile body 1. When the first toothed plate 42 moves upward, the second toothed plate 44 retracts and tightens the second spring 45, reducing the space occupied. The relief groove 43 is designed to facilitate the extension or retraction of the second toothed plate 44.

[0029] Specifically, rack plate 42 is engaged with the surface of rack post 41, and rack plate 44 is engaged with the surface of rack post 41. There are two sets of rack post 41, rack plate 42, clearance groove 43 and rack plate 44, and each set has two clearance grooves 43 and two rack plates 44.

[0030] The effect achieved by the above components is as follows: setting two sets of rack plates 44, and setting two rack plates 44 in each set, is to increase structural stability.

[0031] Specifically, a spring 45 is fixedly connected to the surface of the rack plate 44, and the end of the spring 45 away from the rack plate 44 is fixedly connected to the surface of the receiving groove 2.

[0032] The effect achieved by the above components is as follows: the second spring 45 is set to prevent the second rack 44 from moving arbitrarily after the first rack 42 moves downward and disengages from the gear post 41, while ensuring that the first rack 42 can smoothly engage when it moves upward and contacts the gear post 41.

[0033] Working principle: By setting up the reinforcement mechanism 3, after the pile 1 is driven into the ground, rotating the screw 301 causes the movable plate 302 to move downwards, driving the insertion rod 303 to slide out from the insertion hole 304 and vertically insert deep into the ground. At the same time, when the movable plate 302 moves downwards to contact the square plate 305, the square plate 305 is compressed downwards and presses the spring 310. The connecting rod 306 drives the linkage plate 307, causing the insertion rod 308 to slide out from the insertion hole 309 and horizontally insert into the ground, thereby reinforcing the pile 1. When inserting or removing the pile 1, the insertion rod can be retracted. Rod 1 303 and insert rod 2 308 are designed to avoid increasing resistance. When the ground is soft, the turntable 312 can be manually rotated to rotate the screw 301. When the ground is hard, the groove 314 can be used in conjunction with a power tool to rotate the screw 301. By setting up the reinforcement mechanism 3, multiple sets of insert rod 1 303 inserted deep into the ground longitudinally and insert rod 2 308 inserted laterally into the ground are used to reinforce the pile 1. Insert rod 1 303 and insert rod 2 308 can also be retracted when inserting and removing the pile 1, which saves effort and effectively improves the stability of the equipment.

[0034] Furthermore, by setting up an auxiliary mechanism 4, when the movable plate 302 moves downward, the first rack plate 42 drives the rack column 41, which in turn drives the second rack plate 44. With the rebound force of the second spring 45, the second rack plate 44 extends out of the clearance groove 43, increasing the contact area between the pile body 1 and the ground surface and improving the stability of the ground pile body 1. When the movable plate 302 moves upward, the second rack plate 44 retracts and tightens the second spring 45, reducing the space occupied. By setting up the auxiliary mechanism 4 and utilizing the extendable and retractable second rack plate 44, the stability of the ground pile body 1 is increased during use, and the space occupied is reduced when not in use, thus effectively improving the convenience of the equipment.
