Description

[0001] This application is a divisional application of the invention patent application with the application date of June 14, 2019, the application number of 2019105158137, and the invention title of "A anti-slide pile for slope treatment". Technical Field

[0002] The invention belongs to the technical field of anti-slide piles, and particularly relates to an anti-slide pile used in slope treatment projects. Background Art

[0003] An anti-slide pile is a pile that penetrates through a landslide body and extends into the stable soil layer below, used to resist the downward sliding force of the landslide body and play a role in stabilizing the slope. It is applicable to shallow and medium-thick landslides and is an extremely important anti-slide treatment measure so far. The effect of the anti-slide pile on the landslide body is to insert the anti-slide pile into the stable stratum below the sliding surface and use the passive earth pressure of the stable soil layer of the anti-slide pile to balance the thrust of the sliding body and increase its stability. When the landslide body slides down, it is resisted by the anti-slide pile, so that the passive earth pressure in front of the pile resists the active earth pressure of the landslide body. At present, for small landslides with potential landslides, when people discover potential landslides, piles will be driven at the landslide site. Moreover, in order to improve the strength, people will fix anchor rods on the formed piles. However, before fixing the anchor rods, it is necessary to dig out the soil in the downhill section of the landslide, then drill anchor rod holes, and then pour the anchor rod holes. This is rather troublesome for small landslides. Therefore, it is very necessary to design an anti-slide pile that can directly drive the formed pile and the anchor rod into the landslide.

[0004] The invention designs an anti-slide pile used in slope treatment projects to solve the above problems. Summary of the Invention

[0005] To solve the above-mentioned defects in the prior art, the invention discloses an anti-slide pile used in slope treatment projects, which is realized by the following technical solutions.

[0006] An anti-slide pile used in slope treatment projects is characterized in that it includes a formed pile, an anchor rod for further fixing the formed pile, and a positioning and installation mechanism for positioning the installation of the anchor rod; through the positioning and installation mechanism, the approximate position of the adjustment mechanism installed on the formed pile can be determined, so that when the anchor rod is inserted, it can perfectly cooperate with the adjustment mechanism on the formed pile, and the anchor rod plays a role in strengthening the formed pile.

[0007] The above-mentioned formed pile includes a pile body and an adjustment mechanism. Among them, two adjustment mechanisms are installed in the pile body composed of reinforced concrete, and the two adjustment mechanisms are distributed up and down in the pile body; the specific number of the adjustment mechanisms on the formed pile can be determined according to the specific situation of the local landslide and the investigation and calculation of the staff, so as to determine the number of anchor rods that need to be fixed on a formed pile, so as to achieve the best stability of the formed pile.

[0008] The above-mentioned adjusting mechanism includes a first return spring, a clamping plate, a trigger swing plate, a limiting arc plate, a fixed rotating shaft, and a roller. There are two obliquely distributed square grooves on the pile body in the up-and-down direction. An obliquely distributed through groove is respectively opened on the inner end faces of the two square grooves. During the insertion process of the anchor rod, since a clamping block is installed on the anchor rod and the anchor rod is relatively long and prone to bending, the height and width of the square grooves and through grooves designed in the present invention are both greater than the height and width of the anchor rod. Its function is to prevent the interference between the anchor rod and the formed pile due to the clamping block installed on the anchor rod or the bending of the anchor rod during the insertion process; a square avoidance groove is respectively opened on the upper and lower end faces of the two square grooves, and a clamping plate groove is respectively opened on the upper and lower end faces of the two square grooves. The four clamping plate grooves correspond to the four square avoidance grooves one by one, and a limiting groove is respectively opened between the corresponding clamping plate groove and the square avoidance groove; the trigger swing plate is composed of an upper swing plate, a limiting clamping plate, a leaf spring, and a lower swing plate. The upper swing plate and the lower swing plate are connected by a hinge. Through the cooperation of the upper swing plate and the lower swing plate, it can prevent the interference between the trigger swing plate and the formed pile caused by the oblique insertion of the anchor rod during the insertion of the anchor rod. During the oblique insertion process of the anchor rod, if the lower swing plate contacts the formed pile, the lower swing plate will swing relative to the upper swing plate under the push of the anchor rod. Through the swing of the lower swing plate, it can prevent the interference between the trigger swing plate and the formed pile during the insertion of the anchor rod; a leaf spring is installed on one side of the upper swing plate and the lower swing plate. The function of the leaf spring is to reset the upper swing plate and the lower swing plate; a limiting clamping plate is installed on the other side of the upper swing plate and the lower swing plate; the function of the limiting clamping plate is to limit the reverse swing of the lower swing plate and the upper swing plate, preventing the lower swing plate from being driven to swing to the other side of the upper swing plate when the anchor rod is pulled out; a roller is installed at the lower end of the lower swing plate. The function of the roller is that when the anchor rod is inserted downward and passes through the corresponding adjusting mechanism on the formed pile, the anchor rod will push the corresponding two trigger swing plates to swing. The swing of the trigger swing plate will drive the limiting arc plate installed on it to swing, so that the limiting arc plate is disengaged from the clamping plate. When the anchor rod is inserted to the specified depth, in order to open the trigger barbs installed on the anchor rod, the anchor rod will be pulled upward by a certain distance. When the anchor rod moves upward, the anchor rod will have a relative movement with the corresponding two trigger swing plates. However, in the present invention, a roller is installed at the lower end of the trigger swing plate. Through the roller, it can prevent the interference between the anchor rod and the trigger swing plate during the upward movement of the anchor rod, so that the trigger swing plate drives the limiting arc plate to move, affecting the limitation of the anchor rod by the clamping plate; a fixed rotating shaft is installed at the upper end of the upper swing plate. The two trigger swing plates are symmetrically installed up and down through the fixed rotating shaft in two square avoidance grooves on both sides of the same square groove among the four square avoidance grooves. A limiting clamping groove is opened on the clamping plate. The two clamping plates are symmetrically installed up and down through sliding fit in two clamping plate grooves on both sides of the same square groove among the four clamping plate grooves, and two first return springs with pre-pressure are symmetrically installed between the upper ends of the two clamping plates and the inner end faces of the corresponding clamping plate grooves;The first reset spring exerts a pushing force on the corresponding clamping plate in the initial state, causing the clamping plate to tend to move inward toward the direction groove opened on the forming pile. When the limiting arc plate that restricts the downward movement of the clamping plate disengages from the limiting card slot opened on the clamping plate, the clamping plate will move downward under the pre-pressure of the corresponding first reset spring; a limiting arc plate is installed on one side of each of the two trigger swing plates, and the two limiting arc plates are respectively matched with the limiting card slots opened on the corresponding clamping plates; in the initial state, the cooperation of the limiting clamping plate and the limiting card slot limits the clamping plate corresponding to the limiting clamping plate and the limiting card slot installed on the forming pile, so that the clamping plate is located on both sides of the square groove opened on the forming pile in the initial state. In the initial state, the clamping plate does not affect the insertion of the anchor rod through the forming pile.;

[0009] The forming pile designed by the present invention is cast from reinforced concrete, and an installation space is left at the position where the adjustment mechanism is installed; taking the adjustment mechanism as a whole, a housing is wrapped on the outside, and then the housing and the adjustment mechanism inside the housing are placed together in the installation space left for installing the adjustment mechanism during the casting of the forming pile.

[0010] The above-mentioned anchor rod includes an anchor rod body, trigger barbs, a trigger mounting block, a clamping block, a connecting slider, a prompt bar, a second return spring, an L-shaped trigger block, a driving gear, a connecting block, a connecting rod, and a driving rack. An installation square groove is formed inside the anchor rod body. A first square opening is formed on the upper side of the front end of the installation square groove. Two sliding grooves are symmetrically formed on both side surfaces of the front end of the installation square groove. Two second square openings are symmetrically formed on the left and right side surfaces of the rear end of the installation square groove. A guiding groove communicating with the rear end face of the anchor rod body is formed on the side surface of each of the two second square openings. Two third square openings are symmetrically formed on the upper and lower side surfaces of the rear end of the installation square groove. The connecting slider is installed in the installation square groove formed on the anchor rod body. The trigger barb is a square plate, and the trigger barb is installed at the front end of the anchor rod body through a swing shaft, and the trigger barb cooperates with the first square opening formed on the anchor rod body. One end of the trigger barb passes through the first square opening and is located above the anchor rod body. The swing shaft cooperates with the sliding groove formed on the anchor rod body. When the anchor rod is pulled out after being driven into the designated position, the soil between the trigger barb and the anchor rod will squeeze the trigger barb, causing the trigger barb to swing. During the swinging process of the trigger barb, the trigger barb will drive the connecting slider connected to it through the connecting rod, causing the connecting slider to move. The driving gear is installed on the swing shaft, and the driving rack is installed on the lower end surface of the front end of the installation square groove formed on the anchor rod body. The driving rack meshes with the driving gear. When the swing shaft rotates driven by the trigger barb, the swing shaft will drive the driving gear to rotate. Since the driving gear meshes with the driving rack and the driving rack is stationary, the driving gear will move on the driving rack during the rotation process. The movement of the driving gear drives the swing shaft to move, the movement of the swing shaft drives the connecting slider to move, and the movement of the connecting slider drives the clamping block to move. The two clamping blocks move under the combined action of the swinging of the trigger barb and the movement of the driving gear. The distance between the clamping blocks installed on the anchor rod and the two clamping plates installed on the formed pile and in a matching state with the anchor rod is compensated by the movement of the two clamping blocks, so that the two clamping blocks installed on the anchor rod and the two clamping plates installed on the formed pile and in a matching state with the anchor rod always maintain contact and cooperation. In the present invention, since the driving gear needs to bear the extrusion force of the soil on the trigger barb when the trigger barb is in a tightened state on the anchor rod, the driving gear and the driving rack designed in the present invention are made of materials with relatively high strength. One end of the connecting rod is installed on the side surface of the trigger barb by means of hinge, and the other end of the connecting rod is installed on the connecting slider.The connecting block is installed at one end of the connecting slider where the connecting rod is not installed. A clamping block is installed at each end of the connecting block, and the two clamping blocks respectively pass through two third square openings formed in the anchor rod body and are located outside the anchor rod body. The movement of the connecting slider drives the movement of the connecting block, and the movement of the connecting block drives the movement of the two clamping blocks installed on it. That is, when the anchor rod is pulled outwards, the swinging of the trigger barbs installed on the anchor rod can drive the two clamping blocks to move towards the side of the formed pile. The movement of the two clamping blocks compensates for the distance between the clamping blocks installed on the anchor rod and the two clamping plates installed on the formed pile and in a matching state with the anchor rod when the anchor rod is pulled out, so that the two clamping blocks installed on the anchor rod and the two clamping plates installed on the formed pile and in a matching state with the anchor rod always maintain contact and cooperation. A spring installation groove is formed in the trigger installation block. Two trigger installation blocks are symmetrically installed on both sides of the anchor rod body, and the two trigger installation blocks are correspondingly matched with two second square openings formed in the anchor rod body. Two L-shaped trigger blocks are installed on the anchor rod body through the spring installation grooves formed in the two trigger installation blocks. One end of each of the two L-shaped trigger blocks is located outside the trigger installation block, and the other end is located in the second square opening formed in the anchor rod body. A second return spring is installed between each of the two L-shaped trigger blocks and the two spring installation grooves formed in the two trigger installation blocks. The second return spring plays a role in resetting the corresponding L-shaped trigger block. When the two L-shaped trigger blocks come into contact and cooperation with the inner end surface of the square groove formed in the formed pile during the downward insertion of the anchor rod, the inner end surface of the square groove will squeeze the two L-shaped trigger blocks, causing the two L-shaped trigger blocks to drive the two prompt bars to move, so that one end of the two prompt bars that was originally flush with the rear end surface of the anchor rod body extends out of the rear end of the anchor rod to play a prompting role for the user. When people find that the prompt bars extend out of the rear end of the anchor rod, they can determine that the anchor rod has been inserted into the designated position, and people will pull the anchor rod outwards in the reverse direction, causing the trigger barbs installed on the anchor rod to open. One end of each of the two prompt bars is installed on one of the two L-shaped trigger blocks, and the other end of the two prompt bars is located in the guide groove formed in the anchor rod body. And in the initial state, the end of the prompt bar located in the guide groove formed in the anchor rod body is flush with the rear end surface of the anchor rod body.

[0011] The anchor rod designed in the present invention is cast from reinforced concrete, and steel blocks are used to replace the positions where the trigger barbs, drive tooth plates, drive gears, trigger installation blocks and clamping blocks are installed, and other parts are cast through specific molds.

[0012] As a further improvement of the present technology, the front end of the above-mentioned anchor rod has a conical end that is convenient for inserting into the soil.

[0013] As a further improvement of the present technology, two guiding blocks are symmetrically installed on both sides of the above-mentioned clamping plate. Two guiding through grooves are symmetrically formed on the inner side surfaces of the four clamping plate grooves. The four clamping plates are respectively installed inside the formed pile by the sliding fit of the two guiding blocks installed on them with the two guiding through grooves formed on the corresponding clamping plate grooves among the four clamping plate grooves; the sliding fit of the two guiding blocks with the two guiding through grooves plays a guiding and limiting role for the corresponding clamping plate.

[0014] As a further improvement of the present technology, one first telescopic rod is respectively installed inside the two first return springs installed between the above-mentioned clamping plate and the corresponding clamping plate groove. One end of the first telescopic rod is installed at the upper end of the clamping plate, and the other end of the first telescopic rod is installed on the inner end surface of the corresponding clamping plate groove; the first telescopic rod can prevent the first return spring from bending during the compression process, affecting the pushing of the clamping plate by the first return spring.

[0015] As a further improvement of the present technology, the above-mentioned clamping plate has a first inclined surface facilitating the cooperation between the clamping plate and the anchor rod.

[0016] As a further improvement of the present technology, the above-mentioned two clamping blocks are connected by a reinforcing sleeve, and the reinforcing sleeve is nested outside the anchor rod; the function of the reinforcing sleeve is to strengthen the two clamping blocks and prevent the two clamping blocks from being damaged during the process of being pushed by the formed pile.

[0017] As a further improvement of the present technology, one end of the above-mentioned L-shaped trigger block located outside the anchor rod has a second inclined surface facilitating the cooperation between the L-shaped trigger block and the square groove formed on the formed pile.

[0018] As a further improvement of the present technology, the above-mentioned driving gear is fixedly installed on the swing shaft by welding.

[0019] As a further improvement of the present technology, the above-mentioned second return spring is a compression spring.

[0020] As a further improvement of the present technology, the above-mentioned positioning and installation mechanism includes a fixed sleeve, a telescopic fixed rod, a locking ring, and a positioning sleeve. The fixed sleeve is installed at the upper end of the formed pile; one end of the telescopic fixed rod is installed on the fixed sleeve, and the other end of the telescopic fixed rod is installed with a positioning sleeve. There is a locking ring on the telescopic fixed rod. The function of the locking ring is to limit the length of the telescopic fixed rod. After the position of the adjusting mechanism on each formed pile is determined and the insertion angle of the anchor rod is also determined, the length of the telescopic fixed rod is determined each time the anchor rod is inserted. People can determine the length of each elongation of the telescopic fixed rod in advance according to the position of the adjusting mechanism on each formed pile and the insertion angle of the anchor rod. The length that the telescopic fixed rod needs to elongate each time can be designed in advance through the locking ring, and the insertion position of the anchor rod can be determined through the locking ring, so that the best matching state between the anchor rod and the adjusting mechanism on the formed pile can be achieved; the technology of the locking ring controlling the elongation length of the telescopic fixed rod is realized through the prior art; during use, after determining the insertion angle of the anchor rod through exploration, set the locking ring, and then manually control the telescopic fixed rod to elongate. When the telescopic fixed rod elongates to the length at which the first anchor rod can be installed, the locking ring will automatically limit the telescopic fixed rod to prevent it from continuing to elongate. After installing one anchor rod, pull the telescopic fixed rod again to make it elongate until the next anchor rod is installed.

[0021] When using the anti-slide pile designed by the present invention, first, through the prior art, the positions and depths of the sliding bed and the sliding zone on the landslide are explored, and then the specific position of the formed pile, the fixing positions and angles of the anchor rods on the formed pile, the sizes of the formed pile and the anchor rods, and the length of the anchor rods are determined to make the impedance of the formed pile to the landslide reach the best; after determination, the formed pile and the anchor rods are inserted into the landslide by a pile driver; to ensure the stability of the formed pile, one-third of the formed pile is driven into the lower side of the sliding bed and two-thirds remain on the upper side of the sliding bed when driving the pile.

[0022] Compared with the traditional anti-slide pile technology, for the anti-slide pile designed in the present invention, after determining the specific position of the formed pile, the fixing position and angle of the anchor rod on the formed pile, the sizes of the formed pile and the anchor rod, and the length of the anchor rod, first, the formed pile is driven into the ground by a pile driver. After the formed pile is driven in, the anchor rod is driven into the ground from the upper side of the landslide through the adjusted positioning and installation mechanism; the processes of excavating the soil, drilling the anchor rod hole, and casting the anchor rod hole before fixing the anchor rod by people are eliminated, and the labor cost is reduced; in the present invention, two square grooves and through grooves are obliquely distributed up and down on the pile body. Designing the square grooves and through grooves to be obliquely distributed can ensure that the anchor rod can smoothly pass through the pile body when being inserted downward, and will not cause interference between the anchor rod and the pile body; moreover, for the anchor rod designed in the present invention, the trigger barbs installed on the anchor rod are simply connected by a connecting slider during the process of driving the clamping block to move, with a simple structure, easy to repair, and easy to cast; at the same time, in the present invention, by simply designing a barb and increasing the strength and size of the barb, the pulling force of the barb on the anchor rod is increased, that is, the stability of the anchor rod to the pile body is improved.

Specific embodiments

[0058] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0059] As Figure 1 、 13 shown, it includes a formed pile 1, an anchor rod 24 for further fixing the formed pile 1, and a positioning and installation mechanism 2 for positioning the installation of the anchor rod 24; through the positioning and installation mechanism 2, the approximate position of the adjusting mechanism 8 installed on the formed pile 1 can be determined, so that when the anchor rod is inserted, it can be perfectly matched with the adjusting mechanism 8 on the formed pile 1, and the anchor rod plays a role in strengthening the formed pile 1.

[0060] As Figure 4 shown, the above-mentioned formed pile 1 includes a pile body 7 and an adjusting mechanism 8, wherein two adjusting mechanisms 8 are installed in the pile body 7 made of reinforced concrete, and the two adjusting mechanisms 8 are distributed up and down in the pile body 7; the specific number of the adjusting mechanisms 8 on the formed pile 1 can be determined according to the specific situation of local landslides and the survey and calculation of the staff, so as to determine the number of anchor rods to be fixed on a formed pile 1, and make the stability of the formed pile 1 reach the best.

[0061] As Figure 5 shown, the above-mentioned adjusting mechanism 8 includes a first return spring 9, a clamping plate 10, a trigger swing plate 11, a limiting arc plate 12, a fixed rotating shaft 19, and a roller 20. Among them, as Figure 6 , 7 shown, two square grooves 14 are formed in the pile body 7 and are obliquely distributed up and down. An obliquely distributed through groove 17 is formed on the inner end surface of each of the two square grooves 14. The oblique distribution facilitates the insertion of the anchor rod. When the anchor rod is being inserted, since the anchor rod is provided with a clamping block 30 and the anchor rod is relatively long and prone to bending, the height and width of the square groove and the through groove designed in the present invention are both larger than the height and width of the anchor rod. Its function is to prevent the interference between the anchor rod and the formed pile 1 due to the clamping block 30 installed on the anchor rod or the bending of the anchor rod during the insertion process. As Figure 8 shown, a square avoidance groove 13 is formed on the upper and lower end surfaces of each of the two square grooves 14, and a clamping plate groove 16 is formed on the upper and lower end surfaces of each of the two square grooves 14. The four clamping plate grooves 16 correspond to the four square avoidance grooves 13 one by one, and a limiting groove 15 is formed between the corresponding clamping plate groove 16 and the square avoidance groove 13. As Figure 11As shown in the figure, the trigger swing plate 11 is composed of an upper swing plate 37, a limit clamping plate 58, a leaf spring 59 and a lower swing plate 60. The upper swing plate 37 and the lower swing plate 60 are connected by a hinge. Through the cooperation of the upper swing plate 37 and the lower swing plate, it can prevent the interference between the trigger swing plate 11 and the formed pile 1 caused by the inclined insertion of the anchor rod when the anchor rod is inserted. During the inclined insertion of the anchor rod, if the lower swing plate 60 contacts the formed pile 1, the lower swing plate 60 will swing relative to the upper swing plate 37 under the push of the anchor rod. Through the swing of the lower swing plate 60, it can prevent the interference between the trigger swing plate 11 and the formed pile 1 during the insertion of the anchor rod; a leaf spring 59 is installed on one side of the upper swing plate 37 and the lower swing plate 60. The function of the leaf spring 59 is to reset the upper swing plate 37 and the lower swing plate 60; a limit clamping plate 58 is installed on the other side of the upper swing plate 37 and the lower swing plate 60; the function of the limit clamping plate 58 is to limit the reverse swing of the lower swing plate 60 and the upper swing plate 37, preventing the lower swing plate 60 from being driven to swing to the other side of the upper swing plate 37 when the anchor rod is pulled out; a roller 20 is installed at the lower end of the lower swing plate 60. The function of the roller 20 is that when the anchor rod is inserted downward and passes through the corresponding adjusting mechanism 8 on the formed pile 1, the anchor rod will push the two corresponding trigger swing plates 11 to swing. The swing of the trigger swing plate 11 will drive the limit arc plate 12 installed on it to swing, so that the limit arc plate 12 is disengaged from the clamping plate 10. After the anchor rod is inserted to the specified depth, in order to open the trigger barbs 27 installed on the anchor rod, the anchor rod will be pulled upward by a certain distance. When the anchor rod moves upward, the anchor rod will have a relative movement with the two corresponding trigger swing plates 11. However, in the present invention, a roller 20 is installed at the lower end of the trigger swing plate 11. Through the roller 20, it can prevent the interference between the anchor rod and the trigger swing plate 11 during the upward movement of the anchor rod, so that the trigger swing plate 11 drives the limit arc plate 12 to move, affecting the limit of the clamping plate 10 on the anchor rod; a fixed rotating shaft 19 is installed at the upper end of the upper swing plate 37, as Figure 5 shown, the two trigger swing plates 11 are symmetrically installed up and down through the fixed rotating shaft 19 in two square avoidance grooves 13 on both sides of the same square groove 14 in the four square avoidance grooves 13, as Figure 12 shown, a limit card slot 57 is opened on the clamping plate 10, as Figure 9 、 10As shown in the figure, two clamping plates 10 are symmetrically installed up and down through sliding fit in two of the four clamping plate grooves 16 located on both sides of the same square groove 14 in the clamping plate grooves 16. Two first return springs 9 with pre-pressure are symmetrically installed between the upper ends of the two clamping plates 10 and the inner end faces of the corresponding clamping plate grooves 16 respectively. The first return spring 9 exerts a pushing force on the corresponding clamping plate 10 in the initial state, so that the clamping plate 10 has a tendency to move towards the inside of the direction groove opened on the forming pile 1. When the limiting arc plate 12 that restricts the downward movement of the clamping plate 10 is disengaged from the limiting card slot 57 opened on the clamping plate 10, the clamping plate 10 will move downward under the pre-pressure of the corresponding first return spring 9. One limiting arc plate 12 is installed on one side of each of the two trigger swing plates 11, and the two limiting arc plates 12 are respectively matched with the limiting card slots 57 opened on the corresponding clamping plates 10. In the initial state, the cooperation of the limiting clamping plate 58 and the limiting card slot 57 plays a limiting role on the clamping plate 10 installed on the forming pile 1 corresponding to the limiting clamping plate 58 and the limiting card slot 57, so that the clamping plate 10 is located on both sides of the square groove 14 opened on the forming pile 1 in the initial state. In the initial state, the clamping plate 10 does not affect the insertion of the anchor rod through the forming pile 1.

[0062] The forming pile 1 designed by the present invention is cast from reinforced concrete, and an installation space is left at the position where the adjustment mechanism 8 is installed. Taking the adjustment mechanism 8 as a whole, a layer of shell is wrapped on the outside, and then the shell and the adjustment mechanism 8 inside the shell are placed together in the installation space left for the installation of the adjustment mechanism 8 when the forming pile 1 is cast.

[0063] As Figure 13 shown, the above-mentioned anchor rod 24 includes an anchor rod body 25, a trigger barb 27, a trigger mounting block 29, a clamping block 30, a connecting slider 39, a prompt strip 43, a second return spring 45, an L-shaped trigger block 48, a driving gear 55, a connecting block 50, a connecting rod 54, and a driving toothed plate 53. Among them, as Figure 19 、 20 shown, an installation square groove 34 is opened on the inner side of the anchor rod body 25, and a first square opening 33 is opened on the upper side of the front end of the installation square groove 34. As Figure 20 shown, two sliding grooves 56 are symmetrically opened on both sides of the front end of the installation square groove 34. As Figure 22 shown, two second square openings 35 are symmetrically opened on the left and right side surfaces of the rear end of the installation square groove 34, and a guide groove 38 communicating with the rear end face of the anchor rod body is opened on the side surface of each of the two second square openings 35. As Figure 21 shown, two third square openings 36 are symmetrically opened on the upper and lower side surfaces of the rear end of the installation square groove 34. As Figure 15 、 23 shown, the connecting slider 39 is installed in the installation square groove 34 opened on the anchor rod body 25. As Figure 14As shown, the trigger barb 27 is a square plate. The trigger barb 27 is mounted at the front end of the anchor rod body 25 through a swing shaft 40, and as Figure 16 shown, the trigger barb 27 cooperates with the first square opening 33 formed on the anchor rod body 25, and the swing shaft 40 cooperates with the chute 56 formed on the anchor rod body 25; one end of the trigger barb 27 passes through the first square opening 33 and is located above the anchor rod body 25; when the anchor rod is pulled out after being driven into the designated position, the soil between the trigger barb 27 and the anchor rod will squeeze the trigger barb 27, causing the trigger barb 27 to swing. During the swinging process of the trigger barb 27, the trigger barb 27 will drive the connection slider 39 connected to it through the connecting rod 54, causing the connection slider 39 to move; the driving gear 55 is mounted on the swing shaft 40, and the driving toothed plate 53 is mounted on the lower end surface at the front end of the mounting square groove 34 formed on the anchor rod body 25. The driving toothed plate 53 meshes with the driving gear 55; when the swing shaft 40 rotates driven by the trigger barb 27, the swing shaft 40 will drive the driving gear 55 to rotate. Since the driving gear 55 meshes with the driving toothed plate 53 and the driving toothed plate 53 is stationary, the driving gear 55 will move on the driving toothed plate 53 during rotation. The movement of the driving gear 55 drives the swing shaft 40 to move, the movement of the swing shaft 40 drives the connection slider 39 to move, and the movement of the connection slider 39 drives the latch 30 to move; the two latches 30 move under the combined action of the swing of the trigger barb 27 and the movement of the driving gear 55. The distance between the two latches 30 mounted on the anchor rod and the two clamping plates 10 mounted on the formed pile 1 and in a mating state with the anchor rod is compensated by the movement of the two latches 30, so that the two latches 30 mounted on the anchor rod and the two clamping plates 10 mounted on the formed pile 1 and in a mating state with the anchor rod always maintain contact and cooperation; in the present invention, since the driving gear 55 needs to bear the extrusion force of the soil on the trigger barb 27 when the trigger barb 27 is in a state of tensioning the anchor rod, the driving gear 55 and the driving toothed plate 53 designed in the present invention are made of materials with higher strength; as Figure 24 shown, one end of the connecting rod 54 is mounted on the side surface of the trigger barb 27 by means of hinge, and the other end of the connecting rod 54 is mounted on the connection slider 39; as Figure 32 shown, the connecting block 50 is mounted at the end of the connection slider 39 where the connecting rod 54 is not mounted, as Figure 30As shown, a clamping block 30 is installed at each end of the connecting block 50, and the two clamping blocks 30 respectively pass through two third square openings 36 formed in the anchor rod body 25 and are located outside the anchor rod body 25. The movement of the connecting slider 39 drives the movement of the connecting block 50, and the movement of the connecting block 50 drives the two clamping blocks 30 installed thereon. That is, when the anchor rod is pulled outwards, the swing of the trigger barbs 27 installed on the anchor rod can drive the two clamping blocks 30 to move towards the side of the formed pile 1. The movement of the two clamping blocks 30 is used to compensate for the distance between the clamping blocks 30 installed on the anchor rod and the two clamping plates 10 installed on the formed pile 1 and in a matching state with the anchor rod when the anchor rod is pulled out, so that the two clamping blocks 30 installed on the anchor rod and the two clamping plates 10 installed on the formed pile 1 and in a matching state with the anchor rod always maintain contact and cooperation; As Figure 28 shown, a spring installation groove 46 is formed in the trigger installation block 29, as Figure 17 , 25 shown, the two trigger installation blocks 29 are symmetrically installed on both sides of the anchor rod body 25, and the two trigger installation blocks 29 are correspondingly matched with two second square openings 35 formed in the anchor rod body 25; As Figure 27 shown, the two L-shaped trigger blocks 48 are installed on the anchor rod body 25 through the spring installation grooves 46 formed in the two trigger installation blocks 29, and one end of each of the two L-shaped trigger blocks 48 is located outside the trigger installation block 29, and the other end is located in the second square opening 35 formed in the anchor rod body 25; As Figure 29 shown, a second return spring 45 is installed between each of the two L-shaped trigger blocks 48 and the two spring installation grooves 46 formed in the two trigger installation blocks 29; The second return spring 45 plays a role in resetting the corresponding L-shaped trigger block 48. When the two L-shaped trigger blocks 48 are in contact and cooperation with the inner end surface of the square groove 14 formed in the formed pile 1 during the downward insertion of the anchor rod, the inner end surface of the square groove 14 will squeeze the two L-shaped trigger blocks 48, so that the two L-shaped trigger blocks 48 drive the two prompt bars 43 to move, so that one end of the two prompt bars 43 that was originally flush with the rear end surface of the anchor rod body extends out of the rear end of the anchor rod to play a prompting role for the user. When people find that the prompt bar 43 extends out of the rear end of the anchor rod, it can be determined that the anchor rod has been inserted into the designated position, and people will pull the anchor rod outwards in the reverse direction, so that the trigger barbs 27 installed on the anchor rod are opened; As Figure 26 shown, one end of each of the two prompt bars 43 is installed on the two L-shaped trigger blocks 48, and the other end of the two prompt bars 43 is located in the guide groove 38 formed in the anchor rod body 25, and in the initial state, the end of the prompt bar 43 located in the guide groove 38 of the anchor rod body 25 is flush with the rear end surface of the anchor rod body.

[0064] The anchor rod designed in the present invention is cast from reinforced concrete. At the positions of the installation trigger barbs 27, the driving tooth plates 53, the driving gears 55, the trigger installation blocks 29 and the clamping blocks 30, steel blocks are used instead, and other parts are cast through specific molds.

[0065] The anchor rod can be customized. The manufacturing process flow is all prior art, and the on-site ground pouring method can also be adopted. In the present invention, the anchor rod is mainly for tensile resistance. Multiple steel bars are installed at the non-hollow positions therein to play a role in tensile resistance.

[0066] To sum up:

[0067] The beneficial effects of the design of the present invention: For this anti-slide pile, after determining the specific position of the formed pile 1, the fixing position and angle of the anchor rod on the formed pile 1, the sizes of the formed pile 1 and the anchor rod, and the length of the anchor rod, first drive the formed pile 1 through a pile driver. After the formed pile 1 is driven in, drive the anchor rod into the ground from the upper side of the landslide through the adjusted positioning and installation mechanism 2; it eliminates the processes of excavating soil, drilling anchor rod holes, and casting the anchor rod holes before people fix the anchor rod, and reduces the labor cost.

[0068] As Figure 14 shown, the front end of the above-mentioned anchor rod has a conical end 28 that is convenient for inserting into the soil.

[0069] As Figure 12 shown, two guide blocks 21 are symmetrically installed on both sides of the above-mentioned clamping plate 10. As Figure 8 shown, two guide through grooves 18 are symmetrically opened on the inner side surfaces of the four clamping plate grooves 16. As Figure 5 shown, the four clamping plates 10 are respectively installed inside the formed pile 1 through the sliding fit of the two guide blocks 21 installed on them with the two guide through grooves 18 opened on the corresponding clamping plate grooves 16 among the four clamping plate grooves 16; the sliding fit of the two guide blocks 21 and the two guide through grooves 18 plays a role of guiding and limiting the corresponding clamping plate 10.

[0070] As Figure 12 shown, one first telescopic rod 22 is respectively installed inside the two first return springs 9 installed between the above-mentioned clamping plate 10 and the corresponding clamping plate groove 16. One end of the first telescopic rod 22 is installed at the upper end of the clamping plate 10, and the other end of the first telescopic rod 22 is installed on the inner end surface of the corresponding clamping plate groove 16; the first telescopic rod 22 can prevent the first return spring 9 from bending during the compression process, affecting the pushing of the first return spring 9 on the clamping plate 10.

[0071] As Figure 12 shown, the above-mentioned clamping plate 10 has a first inclined surface 23 that is convenient for the clamping plate 10 to cooperate with the anchor rod.

[0072] As Figure 31As shown, the above two clamping blocks 30 are connected by a reinforcing sleeve 32, and the reinforcing sleeve 32 is nested outside the anchor rod; the function of the reinforcing sleeve 32 is to strengthen the two clamping blocks 30 and prevent the two clamping blocks 30 from being damaged during the process of being pushed by the formed pile 1.

[0073] As Figure 29 shown, one end of the above L-shaped trigger block 48 located outside the anchor rod has a second inclined surface 47 that facilitates the cooperation between the L-shaped trigger block 48 and the square groove 14 opened on the formed pile 1.

[0074] The above driving gear 55 is fixedly installed on the swing shaft 40 by welding or the driving gear is installed on the swing shaft by a key.

[0075] The above second return spring 45 is a compression spring.

[0076] As Figure 3 shown, the above positioning and installation mechanism 2 includes a fixed sleeve 3, a telescopic fixed rod 4, a locking ring 5, and a positioning sleeve 6. As Figure 2 shown, the fixed sleeve 3 is installed at the upper end of the formed pile 1; As Figure 3 shown, one end of the telescopic fixed rod 4 is installed on the fixed sleeve 3, and a positioning sleeve 6 is installed at the other end of the telescopic fixed rod 4. There is a locking ring 5 on the telescopic fixed rod 4. The function of the locking ring 5 is to limit the length of the telescopic fixed rod 4. After the position of the adjusting mechanism 8 on each formed pile 1 is determined and the insertion angle of the anchor rod is also determined, the length of the telescopic fixed rod 4 is also determined each time the anchor rod is inserted. And people can determine the length that the telescopic fixed rod 4 needs to extend each time according to the position of the adjusting mechanism 8 on each formed pile 1 and the insertion angle of the anchor rod. And through the locking ring 5, the length that the telescopic fixed rod 4 needs to extend each time can be designed in advance. By the locking ring 5, the insertion position of the anchor rod can be determined, so that the best matching state between the anchor rod and the adjusting mechanism 8 on the formed pile 1 can be achieved; the technology of the locking ring 5 controlling the extension length of the telescopic fixed rod 4 is realized through the prior art; during use, after determining the insertion angle of the anchor rod through exploration, set the locking ring 5, and then manually control the telescopic fixed rod 4 to extend. When the telescopic fixed rod 4 extends to the length at which the first anchor rod can be installed, the locking ring 5 will automatically limit the telescopic fixed rod 4 to prevent the telescopic fixed rod 4 from continuing to extend. After installing one anchor rod, pull the telescopic fixed rod 4 again to make it extend until the next anchor rod is installed.

[0077] When using the anti-slide pile designed by the present invention, first, the positions and depths of the sliding bed and the landslide zone on the landslide are surveyed through the prior art, and then the specific position of the formed pile 1, the fixing positions and angles of the anchor rods on the formed pile 1, the sizes of the formed pile 1 and the anchor rods, and the lengths of the anchor rods are determined so that the impedance of the formed pile 1 to the landslide reaches the optimum; after the determination, the formed pile 1 and the anchor rods are inserted into the landslide by a pile driver; in order to ensure the stability of the formed pile 1, one-third of the formed pile 1 is driven into the lower side of the sliding bed and two-thirds remain on the upper side of the sliding bed.

[0078] As Figure 34 shown, preferably, the anchor rod body includes a limiting block that cooperates with the connecting block at one end of the connecting slider. The limiting block slides, and the original limiting block is fixed under the connecting block by the connecting block. After the connecting slider moves, the limiting block moves to the end of the connecting block under the action of the spring to limit the connecting block. When the formed pile transmits the acting force to the anchor rod, the anchor rod can directly transmit the force to the anchor rod body through the limiting block, reducing the stress on the transmission structure.

[0079] Specific working process: When people use the anti-slide pile designed by the present invention, before use, first, the positions and depths of the sliding bed and the landslide zone on the landslide are surveyed by the prior art, and then the specific position of the formed pile 1, the fixing positions and angles of the anchor rods on the formed pile 1, the sizes of the formed pile 1 and the anchor rods, and the lengths of the anchor rods are determined so that the impedance of the formed pile 1 to the landslide reaches the best; after determination, the formed pile 1 is inserted into the landslide by a pile driver; in order to ensure the stability of the formed pile 1, one-third of the formed pile 1 is driven into the lower side of the sliding bed and two-thirds remains on the upper side of the sliding bed when driving the pile; after the formed pile 1 is fixed, then manually control the telescopic fixing rod 4 to extend. When the telescopic fixing rod 4 extends to the length at which the first anchor rod can be installed, the locking ring 5 will automatically limit the telescopic fixing rod 4; then the anchor rod is driven through the guide of the positioning and installation mechanism 2 by a pile driver. When the anchor rod is inserted downward through the corresponding adjusting mechanism 8 on the formed pile 1, the anchor rod will push the corresponding two trigger swing plates 11 to swing. The swing of the trigger swing plates 11 will drive the limit arc plates 12 installed thereon to swing, so that the limit arc plates 12 are disengaged from the clamping plates 10, and the clamping plates 10 move outward. When the anchor rod is driven into the designated position, in order to make the barbs swing to the working position, the anchor rod needs to be pulled out by a section. The soil between the trigger barb 27 and the anchor rod will squeeze the trigger barb 27, causing the trigger barb 27 to swing. During the swinging process of the trigger barb 27, the trigger barb 27 will drive the connecting slider 39 connected thereto through the connecting rod 54 to move; the movement of the connecting slider 39 will drive the connecting block 50 to move, and the movement of the connecting block 50 will drive the two clamping blocks 30 installed thereon to move. That is, when the anchor rod is pulled out, the swing of the trigger barb 27 installed on the anchor rod can drive the two clamping blocks 30 to move toward the side of the formed pile 1. By the movement of the two clamping blocks 30, the distance between the clamping blocks 30 installed on the anchor rod and the two clamping plates 10 installed on the formed pile 1 and in a matching state with the anchor rod is compensated when the anchor rod is pulled out, so that the two clamping blocks 30 installed on the anchor rod and the two clamping plates 10 installed on the formed pile 1 and in a matching state with the anchor rod always maintain contact and cooperation; to prevent the gap between the clamping blocks and the two clamping plates due to the anchor rod being pulled out by a section, thus failing to play the role of anchor rod reinforcement; through the cooperation of the two clamping blocks 30 and the corresponding two clamping plates 10, the anchor rod plays a role in strengthening the formed pile 1.
