[0001] The present invention relates to the technical field of civil engineering, and particularly relates to an inverted barb type self-locking anchoring device and a using method thereof. Background Art

[0002] In existing civil engineering, three-dimensional vegetation nets, reinforced mats and other net surface materials are widely used as protective materials for the slopes of slopes. Such materials are usually fixed with steel nails and U-shaped nails, which can prevent surface erosion and soil and water loss. However, such materials are only net surface structures, and the steel nails and U-shaped nails only fix them close to the slope, and cannot play an anchoring role, and cannot solve the problem of slope sliding. If it is necessary to significantly improve the stability of the shallow layer of such slopes, it is necessary to drive engineering soil nails or rock bolts. The construction of soil nails and rock bolts involves complex processes such as drilling, grouting, and tensioning, and requires various equipment such as scaffolding, drilling rigs, grouting machines, and tensioning cylinders. Professional teams are required for construction. For slopes that have been naturally sloped and are overall stable, it is uneconomical and inconvenient to improve the stability of the shallow layer of the slope surface. Summary of the Invention

By upward tensioning of the steel wire rope, the barbs on the inverted barb type anchor nail open in the soil body, and the internal soil body reaction force is transmitted to the anchor plate on the soil slope surface.

[0006] As a further improvement of the above technical solution:

[0007] As an optimized solution of the above technical solution, the inverted barb type anchor nail includes a connecting shaft rod, and barbs symmetrically hinged on the connecting shaft rod, and the upper end of the connecting shaft rod is connected to the steel wire rope.

[0008] As an optimized solution of the above technical solution, a cap tip is provided at the lower end of the connecting shaft rod.

[0009] As an optimized solution of the above technical solution, the barb includes a barb wing body hinged to the connecting shaft rod, and a barb arc wing surface provided at the other end of the barb wing body, and the opening of the barb arc wing surface faces the anchor plate direction.

[0010] As an optimized solution of the above technical solution, a placement groove is provided on the coupling rod, the barbed wing body is hinged in the placement groove, and the two barbed wing bodies can be placed in the placement groove, and the arc of the barbed arc wing surface fits the outer edge of the coupling rod.

[0011] As an optimized solution of the above technical solution, an outward-turning barbed wing tip is provided at the top of the barbed arc wing surface, and the outward-turning barbed wing tip does not fit the coupling rod.

[0012] As an optimized solution of the above technical solution, a wire rope locking assembly is provided on the anchor plate for locking and fixing the wire rope after the wire rope is tensioned.

[0013] As an optimized solution of the above technical solution, the wire rope locking assembly includes a locking box body fixedly arranged on the anchor plate. A wire rope hole and a fixed inclined groove are arranged in the locking box body. The lower end of the fixed inclined groove communicates with the lower end of the wire rope hole. A ball is arranged at the lower end of the fixed inclined groove, an elastic body is arranged at the upper end, and a cover plate is arranged at the top.

[0014] As an optimized solution of the above technical solution, a reading ratchet type tensioner assembly is further included. The reading ratchet type tensioner assembly includes a tensioner bracket. A wire rope guiding shaft is horizontally rotatably arranged on the tensioner bracket, and a wire rope winding shaft is vertically rotatably arranged. A rotating ratchet is arranged at the upper end of the wire rope winding shaft. A wire rope fixing hole is arranged at the middle position of the wire rope winding shaft. The upper end of the tensioner bracket is rotatably and resetably arranged with a ratchet positioner through a positioning shaft and a positioning spring. The end of the ratchet positioner contacts the rotating ratchet.

[0015] The present invention also provides a use method of the barbed type self-locking anchoring device, including the following steps:

[0016] Step1. Pass the wire rope through the hole at the upper end of the barbed anchor bolt and fix it with a wire rope clip. Manually drive the barbed anchor bolt into the slope soil body by using any one of a hammer, an electric hammer or a pneumatic pick. When conditions permit, it can also be pressed in by an excavator;

[0017] Step2. After the barbed anchor bolt enters the designed depth, pull out the punching rod, and then pass the wire rope exposed on the slope surface through the anchor plate placed on the slope surface, the wire rope hole on the locking box body, the wire rope guiding shaft, and the wire rope fixing hole in sequence, and fixedly arrange the tensioner bracket on the anchor plate;

[0018] Step3. Rotate the rotating ratchet through a torque wrench. The cooperation between the rotating ratchet and the ratchet positioner can realize reverse-stop one-way tensioning. The rotating wire rope winding shaft winds the wire rope to tighten the wire rope, and the barbs in the soil body are pulled open. The barbed anchor bolt after being opened will receive a greater reaction force from the soil body to form an anchoring effect;

[0019] Step 4. The radius of the wire rope wound around the wire rope winding shaft is read through the scale on the wire rope guiding shaft of the ratchet tensioner. According to the conversion relationship between the reading of the torque wrench and the winding radius, the real-time tension value can be obtained by looking up the table. When the pre-tension in the early stage reaches a certain designed value, stop the tensioning.

[0020] Step 5. After the tensioning stops, the wire rope will naturally retract under the action of the soil body and its own elasticity, which will drive the rolling of the balls in the anchor plate locking box. Due to the setting of the fixed inclined groove in the locking box, the balls in the locking box will move towards the direction close to the wire rope, thereby producing a locking effect on the wire rope, so as to achieve self-locking under the given tension condition.

[0021] Step 6. Cut the wire rope, remove the tensioner bracket, and complete the slope anchoring.

[0022] Compared with the existing technology, the beneficial effects of the present invention are:

[0023] 1. Compared with the traditional soil nails and anchor bolts, this solution has simple procedures, does not require large-scale professional equipment, does not require a professional team, and can be operated by a single ordinary worker for driving and tensioning.

[0024] 2. Compared with U-shaped nails used for slope material protection, etc., the anchor nails of this device penetrate deep into the soil body, provide a controllable pre-tension for the slope through tensioning, make the anchor plate press tightly against the slope material, and can provide a more effective slope anchoring force, thus solving the problem of shallow surface sliding of soil slopes that cannot be solved by steel nail and U-shaped nails.

[0025] 3. The present invention provides a wire rope self-locking device, which can self-lock when the tension reaches a suitable value, does not require manual locking, is simple to operate. At the same time, after the wire rope is self-locked by the locking box, it will maintain the pre-tension in the early stage, so as to tighten the anchor plate, and the anchor plate will tightly press the slope protection material, achieving the effect of force transmission from point to surface.

[0026] 4. The present invention also provides a corresponding readable ratchet type tensioner, which is convenient for tensioning the wire rope. At the same time, the ratchet method is adopted to prevent rotation during the tensioning process, ensure the tensioning efficiency. At the same time, the wire rope guiding shaft is provided with a scale, and through the scale reading and the reading of the torque wrench, the pre-tension value in the early stage can be obtained.

[0040] 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.

[0041] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The technical solution discloses a barbed self-locking anchor device for shallow soil reinforcement, which mainly includes three parts: 1. a barbed anchor 1; 2. a self-locking anchor plate 3; 3. a ratchet tensioner 4 with readable data;

[0044] As attached Figure 1 As shown, it is a structural diagram of a barbed anchor 1, and its specific structure is as follows:

[0045] The barbed anchor 1 is composed of a cap tip 14, barbs 12 and a coupling rod 11. The barbs 12 are symmetrically arranged in pairs on the left and right sides of the coupling rod 11 and connected to the coupling rod 11 through an axle pin. Although there is only one pair in the attached figure, the corresponding barbs 12 can be quantitatively increased as needed. The main purpose of increasing the barbs 12 is to increase the tension. Therefore, the increased pairs of barbs 12 should be distributed at a certain angle to each other when viewed from above, and should not overlap as much as possible.

[0046] At the same time, a through placement groove 13 is provided on the coupling rod 11. When the barb 12 is driven into the soil, it is retracted and parallel to the coupling rod 11 in the vertical direction. When tensioning, the soil squeezes the outward-turned barb wing tip 123 of the barb 12, so that the barb 12 is unfolded inside the soil, and the barb-type anchor nail 1 forms an anchor shape. Therefore, in order to meet this function, the barb 12 includes three parts:

[0047] One is a barbed wing 121 that is rotatably arranged in the coupling rod 11 through an axle pin, and at the same time, the length of the barbed wing 121 should correspond to the placement slot 13, so that it can be completely placed in the closed state, and the barbed wing 121 of the two barbs 12 should be staggered, so that both barbed wing 121 can be placed. The barbed wing 121 is placed in the coupling rod 11, which can reduce the penetration resistance when the barb-type anchor 1 is driven in, and can also reduce the side resistance when the barbs 12 are opened;

[0048] Two barbed arc wing surfaces 122 connected to the ends of the barbed wing bodies 121. When the barbs 12 are in a vertical state, the barbed arc wing surfaces 122 can fit with the outer edge of the connecting rod 11. The reason for setting the arc shape is to fit with the connecting rod 11, which can reduce the soil resistance during driving. After opening, the arc surface contacts the soil and can provide a greater reaction force;

[0049] There are three everted barbed wing tips 123 provided at the end of the barbed arc wing surface 122. When the barbs 12 are in a closed state, the everted barbed wing tips 123 face outward and do not contact the connecting rod 11. This design is to prevent the barbed arc wing surface 122 from being unable to open due to excessive tight contact during tensioning. The existence of the everted barbed wing tips 123 provides an area for contact with the soil and being squeezed during tensioning, ensuring that the barbs 12 can open.

[0050] Threads are provided at the lower end of the connecting rod 11, and a cap tip 14 is connected through the threads. Its main purpose is to reduce resistance when driving into the soil and prevent sediment from squeezing the pin connection part of the barbs 12.

[0051] As attached Figure 2 Shown in the figure is the structural diagram of the self-locking anchor plate 3, which is connected to the barbed anchor bolt 1 through the steel wire rope 2. The specific structure of the self-locking anchor plate 3 is as follows:

[0052] It is mainly composed of an anchor plate 3 and a locking box body 31 (the locking box body 31 includes a box body, balls 34, an elastic body 35, and a cover plate 36). The locking box body 31 is processed with 4 fixed screw holes, 2 ball-pulling holes, 1 inclined groove, 321 steel wire rope holes, and 1 cover plate groove. The balls 34 and the elastic body 35 are placed in the inclined groove, and the cover plate 36 is placed in the cover plate groove for encapsulating the balls 34 and the elastic body 35. For the elastic body 35, elastic materials such as sponge or rubber can be used.

[0053] The locking box body 31 is connected to the anchor plate 3 by four screws, and there are interconnected steel wire rope holes 32 and a fixed inclined groove 33 in the locking box.

[0054] When the steel wire rope 2 is tensioned outward, when the steel wire rope 2 passes through the steel wire rope hole 32 of the locking box body 31 towards the outside of the slope body, it drives the balls 34 to move upward to the fixed inclined groove 33. The balls 34 do not squeeze the steel wire rope 2. After the tensioning is completed, when the steel wire rope 2 rebounds under the action of the soil and its own elasticity, it drives the balls 34 to move downward to the inclined groove, and the balls 34 will squeeze the steel wire rope 2 to lock the steel wire rope 2, achieving the purpose of self-locking.

[0055] The setting of the elastic body 35 ensures that the balls 34 can contact the steel wire rope 2 at any time, so that they can be driven by the steel wire rope to move in the same direction; after the steel wire rope 2 is locked by the locking box, it will maintain the pre-tension in the early stage, thus tightening the anchor plate 3, and the anchor plate 3 will tightly press the slope protection material, achieving the effect of force transmission from point to surface.

[0056] At the same time, it can be known from the attached figure that the shape of the anchor plate 3 is circular, and the locking box body 31 is located at its center position. However, the anchor plate 3 can also be square or irregular. But to ensure the uniformity of the force on the anchor plate 3, the locking box body 31 must be located at a point where the surrounding forces are uniform.

[0057] Meanwhile, the above-mentioned anchor plate 3 and the locking box body 31 are of a combined type. However, the anchor plate 3 and the locking box body 31 in this technical solution can also be of an integral type, that is, the locking box and the anchor plate 3 are integrally cast without assembly. At the same time, a ball 34, an elastic body 35 and a cover plate 36 are provided in cooperation.

[0058] As shown in the Figure 3 accompanying figure, there is a readable ratchet type tensioner 4 (which is one of the ways to tension the steel wire rope 2. For related components that can also tension the steel wire rope 2, they belong to simple replacements of the technical solution). Its specific structure is as follows:

[0059] The readable ratchet type tensioner 4 includes a tensioner bracket 41, a steel wire rope winding shaft 43, a rotating ratchet 44, a steel wire rope guiding shaft 42, a ratchet positioner 46, a positioner shaft, a positioner limit pin, and a position spring.

[0060] The tensioner bracket 41 is the main structure. Each part is installed on the bracket through openings. At the same time, a handle is provided on the bracket for convenient operation. The tensioner bracket 41 is provided with a slot corresponding to the anchor plate 3 to facilitate positioning during tensioning.

[0061] A steel wire rope guiding shaft 42 is horizontally rotatably arranged on the tensioner bracket 41, and a steel wire rope winding shaft 43 is vertically rotatably arranged. A rotating ratchet 44 is arranged at the upper end of the steel wire rope winding shaft 43. At the same time, a corresponding steel wire rope fixing hole 45 is arranged at the middle position of the steel wire rope winding shaft 43. The steel wire rope winding shaft 43 and the rotating ratchet 44 are arranged as a concentric integral shaft structure. For the ratchet positioner 46, it is arranged at the upper end of the tensioner bracket 41 through the ratchet positioner 46 shaft, the positioner limit pin and the position spring. The end of the ratchet positioner 46 is in contact with the rotating ratchet 44.

[0062] Before tensioning, the steel wire rope 2 passes through the self-locking anchor plate 3 and then turns horizontal on the steel wire rope guiding shaft 42, and then passes through the steel wire rope fixing hole 45. During tensioning, a torque wrench acts on the upper end of the rotating ratchet 44, and the steel wire rope winding shaft 43 rotates to wind the steel wire rope 2, thereby tightening the steel wire rope 2, promoting the barbed anchor nails 1 to open inside the soil body and the steel wire rope 2 to generate prestress. When the torque wrench does not act, the positioner acts on the ratchet to prevent the ratchet shaft from rotating back, ensuring the tensioning efficiency.

[0063] At the same time, a scale is provided on the steel wire rope guiding shaft 42 or an external scale is provided. Through the scale reading and the torque wrench reading, the pre-tension force in the early stage can be obtained.

[0064] As can be seen from the above, this technical solution provides a structure for tensioning the steel wire rope 2 by using a ratchet method and quantifying and controlling the pre-tension force in the early stage. For other similar solutions that can meet the requirements, they should also belong to simple replacements of this technical solution.

[0065] As shown in theFigure 4 As shown in Figure 5 Figure 1, it is the structure diagram of the using process of this technical solution. The specific steps are as follows:

[0066] Step 1: Pass the steel wire rope 2 through the hole at the upper end of the coupling rod 11 and fix it with a steel wire rope clip. Manually use any one of a hammer, an electric hammer or an electric pick (any tool of the same type can be used) to drive the barbed anchor bolt 1 into the slope soil body with a punch rod. When conditions permit, it can also be pressed in by an excavator;

[0067] Step 2: After the coupling rod 11 enters the designed depth, pull out the punch rod. Then pass the steel wire rope 2 exposed on the slope surface through the anchor plate 3 placed on the slope surface, the steel wire rope hole 32 on the locking box body 31, the steel wire rope guiding shaft 42, and the steel wire rope fixing hole 45 in sequence, and fixedly set the tensioner bracket 41 on the anchor plate 3;

[0068] Step 3: Rotate the ratchet wheel 44 through a torque wrench. The cooperation between the rotating ratchet wheel 44 and the ratchet wheel retainer 46 can achieve reverse-stop one-way tensioning. The rotating steel wire rope winding shaft 43 winds the steel wire rope 2 to tighten the steel wire rope 2, and the barbs 12 in the soil body are pulled open. The opened barbed anchor bolt 1 will receive a greater reaction force from the soil body, which is transmitted to the anchor plate 3 arranged on the ground surface through the steel wire rope 2 to form an anchoring effect;

[0069] Step 4: The radius of the steel wire rope 2 wound on the steel wire rope winding shaft 43 is read through the scale on the steel wire rope guiding shaft 42 of the ratchet tensioner. According to the conversion relationship between the reading of the torque wrench and the winding radius, the real-time tension value can be obtained by looking up the table. When the pre-tension in the early stage exceeds a certain designed value, stop the tensioning;

[0070] Step 5: After the tensioning stops, the steel wire rope 2 naturally retracts under the action of the soil body and its own elasticity, which will drive the ball 34 in the locking box of the anchor plate 3 to roll. Due to the setting of the inclined groove in the locking box, the ball 34 in the locking box will move towards the direction close to the steel wire rope 2, so as to produce a locking effect on the steel wire rope 2, thus realizing self-locking under the given tension condition;

[0071] Step 6: Cut off the steel wire rope 2, take out the tensioner bracket 41, and complete the slope surface anchoring.

[0072] The above is only the preferred specific implementation manner 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
