Description

Technical Field

[0001] This invention relates to the field of rock slope restoration technology, and more particularly to a soil and water conservation device for ecological restoration of rock slopes. Background Technology

[0002] The ecological restoration of steep slopes in abandoned quarries typically requires the use of the following technologies: slope grading treatment, slope greening, and slope drainage and water storage. Among these, the existing slope grading treatment method for quarries mainly involves directional blasting. Blasting can loosen the rock mass around the blasting area, making it prone to becoming a dangerous rock mass and posing a significant safety hazard.

[0003] When anchor bolts are used to fix rock slopes, such as in the form of anchored frame beams, traditional anchor bolt anchoring methods typically involve single grouting or single mechanical expansion, requiring individual anchoring, which is slow. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil and water conservation device for ecological restoration of rocky slopes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil and water conservation device for ecological restoration of rocky slopes includes a base plate and an inclined plate fixed to one end of the base plate. A groove is provided on the upper side of the base plate, and a drainage hole is provided in the groove. An installation hole is provided at one end of the base plate, and an anchor rod is hingedly connected in the installation hole. A reset torsion spring is provided on the hinge axis of the anchor rod.

[0007] The anchor bolt includes an embedded cylinder, with a prefabricated bag fixedly connected to the bottom of the embedded cylinder. The prefabricated bag is filled with adhesive material, and a squeezing device is slidably connected inside the embedded cylinder. The squeezing device is used to puncture the prefabricated bag.

[0008] Preferably, the adhesive material is crushed stone and cement slurry, and the prefabricated bag has several compartments, in which crushed stone and cement slurry are filled at intervals.

[0009] Preferably, through holes are uniformly provided at the bottom end of the embedded cylinder.

[0010] Preferably, the extrusion device includes a horizontal plate, which is fixedly connected inside the embedded cylinder. The horizontal plate is slidably connected to an extrusion rod along the axial direction of the embedded cylinder. The lower end of the extrusion rod is provided with a cone. The upper end of the extrusion rod is fixedly connected to a toothed plate. The upper inner wall of the embedded cylinder is rotatably connected to a gear. The main shaft of the gear is fixedly connected to a ratchet. One end of the hinge shaft of the anchor rod is fixedly connected to the inner wall of the mounting hole. The other end of the hinge shaft extends into the embedded cylinder and is provided with a rocker arm, which is set corresponding to the ratchet arm.

[0011] Preferably, the inclined plate is a fixed connecting pressure plate away from the base plate.

[0012] Preferably, the pressure plate is provided with comb-tooth grooves evenly distributed.

[0013] Preferably, the bottom of the base plate is fixedly connected with cross plates at intervals.

[0014] Preferably, an ear plate is fixedly connected to the upper side of the inclined plate, and the ear plate is fixedly connected to the traction cable.

[0015] The advantages of this invention are as follows: The soil and water conservation device for ecological restoration of rocky slopes provided by this invention involves throwing soil blocks onto the slope. Some of the larger soil blocks press down on the inclined plate, causing the bottom plate and the inclined plate to rotate relative to the anchor rod. The device is pulled up and down by the lugs of the traction cable, which facilitates the breaking of soil blocks and the compaction of soil around the bottom plate and the inclined plate, reducing the impact of rainwater erosion. The groove facilitates soil storage and drainage.

[0016] This invention uses through holes distributed tangentially around the embedding cylinder. As the pressure rod is pushed down, the cone pierces the precast bag. With the downward push of the pressure rod, the action of the ball bearings and spiral grooves causes the cylinder to deflect. To facilitate the embedding cylinder entering the pre-drilled hole, the diameter of the pre-drilled hole is larger than that of the embedding cylinder. This allows the cone, with its inclined groove, to push the crushed stone from the through hole to the outside of the embedding cylinder. Since the embedding cylinder may be eccentric within the pre-drilled hole, this extrusion method facilitates the filling of cement mortar and crushed stone into the gap between the embedding cylinder and the pre-drilled hole, thereby enhancing the solidification effect of the anchor. As shown in the figure, the cement slurry is squeezed out in the forward direction, ensuring that the cement slurry does not directly face the inner wall of the pre-drilled hole, making it easier to discharge. Unlike existing grouting and mechanical expansion anchoring methods, this invention can achieve batch anchoring and facilitates the solidification of slope soil. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figure 1-6 As shown, the present invention provides a soil and water conservation device for ecological restoration of rocky slopes, including a base plate 1 and an inclined plate 2 fixed to one end of the base plate 1. A groove 11 is provided on the upper side of the base plate 1, and a drainage hole 12 is provided in the groove of the groove 11. The groove 11 has an arc-shaped structure to facilitate drainage. An installation hole 13 is provided at one end of the base plate 1. An anchor rod 3 is hinged in the installation hole 13, and a reset torsion spring is provided on the hinge shaft 30 of the anchor rod 3.

[0025] Ear plate 21 is fixedly connected to the upper side of inclined plate 2. The ear plate 21 is fixedly connected to the traction cable. The traction cable is a straw rope or steel wire rope, which can be reused. Alternatively, the straw rope can be left on the slope and buried with soil to stabilize the soil.

[0026] The anchor bolt 3 includes an embedded cylinder 31. A precast bag 32 is fixedly connected to the bottom of the embedded cylinder 31. The precast bag 32 is filled with an adhesive material, which is crushed stone 322 and cement grout 323. The precast bag 32 has several cavities 321. The crushed stone 322 and cement grout 323 are filled in the cavities 321 at intervals. Before construction, the cement grout 323 is pushed into the cavities 321 through the injection pipe. An extrusion device 4 is slidably connected inside the embedded cylinder 31. The extrusion device 4 is used to puncture the precast bag 32. Through holes 311 are evenly provided at the bottom of the embedded cylinder 31 to facilitate the discharge of cement grout to the outside of the embedded cylinder 31 and contact the inner wall of the pre-drilled hole on the slope, thereby playing a further reinforcement role.

[0027] Several pre-drilled holes are drilled on the rocky slope. Anchor rods 3 are inserted into the pre-drilled holes. Soil is dumped on the slope where the invention is installed. The dumping position is located on the slope above the corresponding base plate 1 and inclined plate 2. Soil clods roll down the slope and are blocked by the base plate 1 and inclined plate 2. After grass seeds are sown, the base plate 1 and inclined plate 2 can be used as a base to fix the soil and green the rocky slope.

[0028] When soil clods are thrown onto the slope, some of the larger clods press down on the inclined plate 2, causing the bottom plate 1 and the inclined plate 2 to rotate relative to the anchor rod 3. The ear plate 21 of the traction cable pulls the soil up and down, which facilitates the breaking of soil clods and the compaction of soil around the bottom plate 1 and the inclined plate 2, reducing the impact of rainwater erosion. The groove 11 is convenient for storing soil and drainage.

[0029] As a specific embodiment of the extrusion device 4 of the present invention, the extrusion device 4 includes a horizontal plate 41, which is fixedly connected inside the embedded cylinder 31. The horizontal plate 41 is slidably connected to the extrusion rod 42 along the axial direction of the embedded cylinder 31. The lower end of the extrusion rod 42 is provided with a cone 43. The upper end of the extrusion rod 42 is fixedly connected to a toothed plate 44. The upper inner wall of the embedded cylinder 31 is rotatably connected to a gear 45. The main shaft of the gear 45 is fixedly connected to a ratchet 46. One end of the hinge shaft 30 of the anchor rod 3 is fixedly connected to the inner wall of the mounting hole 13. The other end of the hinge shaft 30 extends into the embedded cylinder 31 and is provided with a rocker arm 47. The rocker arm 47 is provided corresponding to the ratchet 46.

[0030] Based on the extrusion device 4, in order to improve the bonding strength between the lower end of the embedded cylinder 31 and the pre-drilled hole of the slope, a spiral groove 8 is provided on the inner wall of the embedded cylinder 31. The lower end of the pressure rod 42 is fixedly connected to the slider 81. The cylinder 82 is slidably connected inside the embedded cylinder 31. The upper side of the cylinder 82 is provided with an annular groove 83, which is adapted to the slider 81. The outer circle of the cylinder 82 is provided with a ball bearing 84, which is located in the spiral groove 8. The cone 43 is eccentrically fixedly connected to the bottom of the cylinder 82, and the cone 43 is provided with an inclined groove 85.

[0031] The through holes 311 are tangentially distributed around the embedded cylinder 31. As the pressure rod 42 pushes downwards, the cone 43 pierces the precast bag 32. With the downward push of the pressure rod 42, the action of the ball bearings 84 and the spiral groove 8 causes the cylinder 82 to deflect. To facilitate the entry of the embedded cylinder 31 into the pre-drilled hole, the diameter of the pre-drilled hole is larger than that of the embedded cylinder 31. This allows the cone 43, carrying the inclined groove 85, to push the crushed stone from the through holes 311 outwards from the embedded cylinder 31. Furthermore, since the embedded cylinder 31 may be eccentrically positioned within the pre-drilled hole, this extrusion method facilitates the filling of cement mortar and crushed stone into the gap between the embedded cylinder 31 and the pre-drilled hole, thereby strengthening the curing effect of the anchor bolt 3. Figure 6 The cement slurry is extruded in the direction shown in the diagram, so that the cement slurry is not directly perpendicular to the inner wall of the pre-drilled hole, making it easier to discharge the cement slurry.

[0032] This invention differs from existing anchoring methods such as grouting and mechanical expansion, and can achieve the effect of batch anchoring, which facilitates the solidification of slope soil.

[0033] Furthermore, a fixed connecting plate 5 is provided on the inclined plate 2 away from the bottom plate 1. The pressure plate 5 is evenly provided with comb grooves 51. When soil is thrown on the inclined plate 2 and the bottom plate 1 rotate around the anchor rod 3, the soil clods thrown on the slope are pressed to the bottom of the inclined plate 2 and the bottom plate 1, which helps to fix the soil.

[0034] Furthermore, the bottom of the base plate 1 is fixedly connected with cross plates 6 at intervals. The cross plates 6 are made of bamboo strips, which can bend when the inclined plate 2 rotates, thus pressing down the soil. After the soil is thrown, they facilitate the entanglement of plant roots in the soil, further fixing the soil.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
