Description

Technical Field

[0001] The present invention relates to the technical field of anti-slide piles, and particularly to a new type of slope retaining and anchor-pulling anti-slide pile. Background Art

[0002] An anti-slide pile is a pile column that penetrates through a landslide body and extends deep into the sliding bed, used to resist the sliding force of the sliding body and play a role in stabilizing the slope. It is applicable to shallow and medium-thick landslides and is a main measure for anti-slide treatment. The action of the anti-slide pile on the landslide body is to use the resistance (anchoring force) of the stable formation below the sliding surface into which the anti-slide pile is inserted 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, making the sliding body in front of the pile reach a stable state. Wooden piles, steel piles, concrete, and reinforced concrete piles can be selected according to the thickness of the sliding body, the magnitude of the thrust, waterproof requirements, and construction conditions, etc.

[0003] However, when the anchor rod of the existing slope retaining and anchor-pulling anti-slide pile is connected and installed to the anti-slide pile, its installation angle is fixed and cannot be adjusted, making it difficult to adapt to landslide bodies in different situations and having a small scope of application; the anchor rod of the existing slope retaining and anchor-pulling anti-slide pile is a smooth rod body, and the friction and bite force between it and the mortar are small; moreover, both the body of the existing slope retaining and anchor-pulling anti-slide pile and the anchor rod are hollow structures, and their strength needs to be enhanced. Summary of the Invention

[0004] The present invention discloses a new type of slope retaining and anchor-pulling anti-slide pile, aiming to solve the technical problems in the background art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A new type of slope retaining and anchor-pulling anti-slide pile includes an anchor rod and an anti-slide pile body. The anti-slide pile body is filled with quartz sand. An installation hole is opened above one side of the anti-slide pile body, and a vertical groove is opened above the opposite side of the anti-slide pile body to the installation hole. The anchor rod passes through the installation hole and the vertical groove. An installation box is fixedly connected below the vertical groove on the anti-slide pile body. A support mechanism for supporting the anchor rod is provided in the installation box. The anchor rod is hollow inside. An installation box is horizontally welded below the inside of the anchor rod. The opposite ends of the installation box are both slidably connected with pointed cones. Both pointed cones penetrate the side wall of the anchor rod and are slidably connected with the anchor rod. A plug rod penetrates through the middle of the installation box. A synchronous movement mechanism for driving the two pointed cones to move synchronously is provided in the installation box. Four water extraction branch pipes are vertically installed at the four corners inside the anti-slide pile body, and a cross reinforcing rib is welded between the four water extraction branch pipes.

[0007] Multiple mounting boxes horizontally arranged inside the anchor rod can provide internal support for the hollow anchor rod, making it stronger and less prone to deformation; the quartz sand can filter the water flowing into the anti-slide pile body, thereby preventing impurities from being sucked into the pumping branch pipe and causing blockage.

[0008] In a preferred solution, the support mechanism includes a support member and a lead screw. The lead screw is vertically and rotatably connected inside the installation box. A lifting sleeve rod is sleeved outside the lead screw. The lead screw and the lifting sleeve rod are connected by threads. The top end of the lifting sleeve rod extends out of the installation box and is slidably connected to the installation box. The support member is welded to the top end of the lifting sleeve rod. The bottom end of the lead screw is fixedly connected with a driven bevel gear. A driving bevel gear is meshed on the side of the driven bevel gear. The other side of the driving bevel gear is horizontally welded with a rotating rod. The other end of the rotating rod extends out of the installation box and is rotatably connected to the installation box. A turntable is welded to the other end of the rotating rod. Sliders are welded to both sides of the bottom of the lifting sleeve rod. Vertical sliding grooves are opened on the opposite inner walls of the two sides inside the installation box. The two sliders are respectively slidably connected inside the two sliding grooves.

[0009] By providing a support mechanism, the anchor rod is passed through the installation hole and the vertical groove. The anchor rod is placed on the support member. The turntable drives the rotating rod to rotate. The rotating rod drives the driving bevel gear to rotate. The driving bevel gear drives the lead screw to rotate through the driven bevel gear, so that the lifting sleeve rod rises and falls on the lead screw, driving the support member to rise and fall, thereby driving the anchor rod on the support member to change the angle. After adjusting to the required angle, the position between the anchor rod and the anti-slide pile body is fixed by using existing fixing technology. The installation angle of the anchor rod can be adjusted, which can adapt to landslide bodies in different situations and has a wider application range.

[0010] In a preferred solution, the position of the vertical groove is lower than the installation hole. There are multiple mounting boxes and they are evenly distributed along the direction of the anchor rod below the inside of the anchor rod. Water inlet holes are opened on the opposite sides outside the anti-slide pile body. There are multiple water inlet holes.

[0011] The water flowing down from the landslide body can enter the anti-slide pile body through multiple water inlet holes.

[0012] In a preferred solution, the synchronous movement mechanism includes triangular blocks. There are two triangular blocks. The two triangular blocks are symmetrically and slidably connected inside the mounting box. The inclined surfaces of the two triangular blocks face each other. Connecting plates are welded to the ends of one side of the two triangular blocks. Springs are welded to the opposite sides of the two connecting plates away from each other. The other ends of the two springs are respectively welded to the opposite inner walls of the mounting box. Sharp cones are welded to the sides of the two triangular blocks away from each other.

[0013] By setting up a synchronous movement mechanism, after the anchor rod is installed, the insertion rod is inserted into multiple installation boxes in sequence. When the insertion rod is inserted into the interior of the installation box, the top end of the insertion rod abuts against the inclined surfaces of the two triangular blocks, thereby squeezing the two triangular blocks to both sides, driving the two pointed cones to protrude from the interior of the installation box and the anchor rod. When the insertion rod is inserted to the lowest end of the anchor rod, the pointed cones in all the installation boxes protrude and are located on both sides of the anchor rod. The multiple pointed cones make the outer surface of the anchor rod no longer smooth, thereby strengthening the frictional force and biting force between the anchor rod and the mortar.

[0014] In a preferred solution, a locking bolt is screwed on the side surface of the top end of the anchor rod. The other end of the locking bolt penetrates through the top end of the insertion rod and is threadedly connected to the insertion rod. All four water pumping branch pipes are in an "L" shape, and the top ends of the four water pumping branch pipes communicate with the same water pumping main pipe. The other end of the water pumping main pipe extends out of the ground and is connected to a water pump.

[0015] After the insertion rod is completely inserted into the interior of the anchor rod, the insertion rod and the anchor rod can be fixed together by screwing on the locking bolt to prevent the insertion rod from falling off; regularly turning on the water pump to pump the water entering the interior of the anti-slide pile body to the ground through the water pumping main pipe and the four water pumping branch pipes can drain the water and avoid excessive groundwater from affecting the slope stabilizing force.

[0016] In a preferred solution, multiple cross stiffeners are provided and are evenly distributed vertically between the four water pumping branch pipes, and the position of the uppermost cross stiffener is lower than the position of the vertical groove.

[0017] The cross stiffeners arranged inside the anti-slide pile body and the filled quartz sand can provide internal supporting force for the hollow anti-slide pile body, making it stronger in strength and not easily deformed.

[0018] As can be seen from the above, the novel slope retaining anchor-pulled anti-slide pile provided by the present invention can adjust the installation angle of the anchor rod, can adapt to landslide bodies in different situations, and has a wider application range; multiple pointed cones make the outer surface of the anchor rod no longer smooth, thereby strengthening the frictional force and biting force between the anchor rod and the mortar; it can provide internal supporting force for the hollow anti-slide pile body and the anchor rod, making it stronger in strength and not easily deformed.

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a new type of slope retaining anchor-pulled anti-slide pile, including an anchor rod 6 and an anti-slide pile body 10. The anti-slide pile body 10 is filled with quartz sand. An installation hole 14 is opened above one side of the anti-slide pile body 10. A vertical groove 2 is opened above the opposite side of the anti-slide pile body 10 and the installation hole 14. The anchor rod 6 passes through the installation hole 14 and the vertical groove 2. (Through holes are provided on the surface of the anchor rod 6, not marked in the figure, so that when pressure grouting, cement mortar can be squeezed into the soil from the through holes to reinforce the soil around the anchor rod 6). A fixing box 7 is fixedly connected below the vertical groove 2 on the anti-slide pile body 10. A support mechanism for supporting the anchor rod 6 is provided in the installation box 7. The inside of the anchor rod 6 is hollow. An installation box 25 is horizontally welded below the inside of the anchor rod 6. The opposite ends of the installation box 25 are both slidably connected with pointed cones 5. Both pointed cones 5 penetrate the side wall of the anchor rod 6 and are slidably connected with the anchor rod 6. An insertion rod 12 passes through the middle of the installation box 25. A synchronous movement mechanism for driving the two pointed cones 5 to move synchronously is provided in the installation box 25. Four pumping branch pipes 9 are vertically installed at the four corners inside the anti-slide pile body 10. A cross stiffener 15 is welded between the four pumping branch pipes 9. The quartz sand can filter the water flow entering the anti-slide pile body 10, thereby preventing impurities from being sucked into the pumping branch pipe 9 and causing blockage. The multiple horizontally arranged installation boxes 25 inside the anchor rod 6 can provide internal support force for the hollow anchor rod 6, making it stronger and not easily deformed.

[0027] Refer to Figure 1 And Figure 4, in a preferred embodiment, the support mechanism includes a support member 3 and a lead screw 17. The lead screw 17 is vertically and rotatably connected to the inside of the installation box 7. A lifting sleeve rod 4 is sleeved outside the lead screw 17. The lead screw 17 and the lifting sleeve rod 4 are connected by threads. The top end of the lifting sleeve rod 4 extends out of the installation box 7 and is slidably connected to the installation box 7. The support member 3 is welded to the top end of the lifting sleeve rod 4.

[0028] Refer to Figure 1 and Figure 4 , in a preferred embodiment, a driven bevel gear 16 is fixedly connected to the bottom end of the lead screw 17. A driving bevel gear 21 is meshed with the side of the driven bevel gear 16. A rotating rod 20 is horizontally welded to the other side of the driving bevel gear 21. The other end of the rotating rod 20 extends out of the installation box 7 and is rotatably connected to the installation box 7. Pass the anchor rod 6 through the installation hole 14 and the vertical groove 2. Place the anchor rod 6 on the support member 3. Drive the rotating rod 20 to rotate through the turntable 8. The rotating rod 20 drives the driving bevel gear 21 to rotate. The driving bevel gear 21 drives the lead screw 17 to rotate through the driven bevel gear 16, so that the lifting sleeve rod 4 rises and falls on the lead screw 17, driving the support member 3 to rise and fall. Thus, the anchor rod 6 on the support member 3 can be driven to change the angle. After adjusting to the required angle, use the existing fixing technology to fix the position between the anchor rod 6 and the anti-slide pile body 10. The installation angle of the anchor rod 6 can be adjusted, which can adapt to landslide bodies in different situations and has a wider application range.

[0029] Refer to Figure 1 and Figure 4 , in a preferred embodiment, a turntable 8 is welded to the other end of the rotating rod 20. Sliders 19 are welded to both sides of the bottom of the lifting sleeve rod 4. Vertical sliding grooves 18 are formed on the opposite inner walls of the two sides inside the installation box 7. The two sliders 19 are respectively slidably connected to the two sliding grooves 18. The sliders 19 being slidably connected to the inside of the sliding grooves 18 can limit the lifting sleeve rod 4 so that it can only rise and fall and cannot rotate with the lead screw 17.

[0030] Refer to Figure 1 and Figure 5 , in a preferred embodiment, the position of the vertical groove 2 is lower than that of the installation hole 14. A plurality of installation boxes 25 are provided and are evenly distributed along the direction of the anchor rod 6 below the inside of the anchor rod 6. Water inlet holes 11 are formed on the opposite outer sides of the anti-slide pile body 10. A plurality of water inlet holes 11 are provided. The water flowing down from the landslide body can enter the inside of the anti-slide pile body 10 through the plurality of water inlet holes 11.

[0031] Refer to Figure 5 , in a preferred embodiment, the synchronous moving mechanism includes triangular blocks 22. There are two triangular blocks 22. The two triangular blocks 22 are symmetrically and slidably connected to the inside of the installation box 25. The inclined surfaces of the two triangular blocks 22 face each other. Connecting plates 24 are welded to the end portions of one side of the two triangular blocks 22.

[0032] Referring to Figure 5 , in a preferred embodiment, springs 23 are welded to the outer sides of the two connecting plates 24 away from each other, and the other ends of the two springs 23 are respectively welded to the opposite inner walls of the mounting box 25. The two pointed cones 5 are respectively welded to the outer sides of the two triangular blocks 22 away from each other. After the anchor rod 6 is installed, the insertion rod 12 is inserted into the plurality of mounting boxes 25 in sequence. When the insertion rod 12 is inserted into the interior of the mounting box 25, its top end abuts against the inclined surfaces of the two triangular blocks 22, thereby squeezing the two triangular blocks 22 to both sides, driving the two pointed cones 5 to protrude from the interior of the mounting box 25 and the anchor rod 6. When the insertion rod 12 is inserted into the lowest end of the anchor rod 6, the pointed cones 5 in all the mounting boxes 25 protrude and are located on both sides of the anchor rod 6. The plurality of pointed cones 5 make the outer surface of the anchor rod 6 no longer smooth, thereby strengthening the frictional force and biting force between the anchor rod 6 and the mortar.

[0033] Referring to Figure 1 and Figure 2 , in a preferred embodiment, a locking bolt 13 is screwed on the side surface of the top end of the anchor rod 6, and the other end of the locking bolt 13 penetrates through the top end of the insertion rod 12 and is threadedly connected to the insertion rod 12. The four water pumping branch pipes 9 are all in an "L" shape, and the top ends of the four water pumping branch pipes 9 communicate with the same water pumping main pipe 1. The other end of the water pumping main pipe 1 extends out of the ground and is connected to a water pump. The water pump is regularly turned on to pump the water entering the anti-slide pile body 10 to the ground through the water pumping main pipe 1 and the four water pumping branch pipes 9, so as to drain the water and avoid excessive groundwater from affecting the slope fixation strength.

[0034] Referring to Figure 1 and Figure 3 , in a preferred embodiment, a plurality of cross stiffeners 15 are provided and are evenly distributed vertically between the four water pumping branch pipes 9, and the position of the uppermost cross stiffener 15 is lower than the position of the vertical groove 2. The cross stiffeners 15 arranged inside the anti-slide pile body 10 and the filled quartz sand can provide internal support force for the hollow anti-slide pile body 10, making it stronger in strength and not easily deformed.

[0035] Working principle: During use, the anchor rod 6 is passed through the mounting hole 14 and the vertical groove 2, and the anchor rod 6 is placed on the support member 3. The turntable 8 drives the rotating rod 20 to rotate, the rotating rod 20 drives the driving bevel gear 21 to rotate, the driving bevel gear 21 drives the lead screw 17 to rotate through the driven bevel gear 16, so that the lifting sleeve rod 4 is lifted and lowered on the lead screw 17, driving the support member 3 to lift and lower, thereby driving the anchor rod 6 on the support member 3 to change the angle. After adjusting to the required angle, the position between the anchor rod 6 and the anti-slide pile body 10 is fixed by using the existing fixing technology. The installation angle of the anchor rod 6 can be adjusted, which can adapt to landslide bodies in different situations and has a wider application range;

[0036] After the anchor rod 6 is installed, the inserting rod 12 is inserted into a plurality of installation boxes 25 in sequence. When the inserting rod 12 is inserted into the interior of the installation box 25, the top end thereof abuts against the inclined surfaces of the two triangular blocks 22, thereby squeezing the two triangular blocks 22 towards both sides, and then driving the two pointed cones 5 to protrude from the interior of the installation box 25 and the anchor rod 6. When the inserting rod 12 is inserted into the lowermost end of the anchor rod 6, the pointed cones 5 in all the installation boxes 25 protrude and are located on both sides of the anchor rod 6. The plurality of pointed cones 5 make the outer surface of the anchor rod 6 no longer smooth, thereby enhancing the frictional force and biting force between the anchor rod 6 and the mortar.

[0037] The cross-shaped reinforcing ribs 15 provided inside the anti-slide pile body 10 and the filled quartz sand can provide internal support for the hollow anti-slide pile body 10, making it stronger in strength and not easily deformed; the plurality of installation boxes 25 horizontally arranged inside the anchor rod 6 can provide internal support for the hollow anchor rod 6, making it stronger in strength and not easily deformed.

[0038] The water flowing down from the landslide body can enter the interior of the anti-slide pile body 10 through a plurality of water inlet holes 11, and the quartz sand can filter the water flowing into the anti-slide pile body 10, thereby preventing impurities from being sucked into and clogging the pumping branch pipe 9. The water pump is regularly turned on to pump the water entering the interior of the anti-slide pile body 10 to the ground by using the pumping main pipe 1 and the four pumping branch pipes 9, so as to drain the water and avoid excessive groundwater from affecting the slope fixing strength.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
