Description
Technical Field
[0001] This utility model relates to the field of slope greening technology, and more specifically, to a reinforcement device for planting grass and hanging nets on roadbed slopes. Background Technology
[0002] In road engineering, the stability of the roadbed slope, as the sloping surfaces on both sides of the roadbed, directly affects road safety. To prevent geological disasters such as landslides and erosion, grass planting slope protection technology is often used—an organic substrate containing grass seeds is sprayed onto the slope surface using a hydroseeding machine, and then covered with non-woven fabric for insulation, moisture retention, and protection against rain erosion. Traditional fixing methods often use steel stakes or discarded short ribs and wooden sticks from the construction site to fix the four corners of the non-woven fabric to the ground.
[0003] However, under strongly weathered sandstone geological conditions, this type of fixing method has significant drawbacks. The sandstone is loose and brittle, making it difficult to insert steel rods securely, and the installation process can easily lead to secondary damage to the slope. At the same time, the steel rods penetrating the non-woven fabric will cause permanent damage, which not only reduces the initial fixing effect but also reduces the number of times the non-woven fabric can be recycled, increasing construction costs and wasting resources. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a reinforcement device for planting grass and hanging netting on roadbed slopes, which solves the above problems.
[0005] This utility model is implemented as follows:
[0006] A reinforcement device for planting grass and hanging netting on roadbed slopes includes a mounting base plate. The top of the mounting base plate has a clamping groove. A clamping assembly is provided on the opposite side of the top of the two clamping grooves. The clamping assembly includes a wing plate provided on the top side of the clamping groove. The top of the wing plate has a second movable hole. An elastic clamping plate is provided in the second movable hole. The top two ends of the mounting base plate have first movable holes. An anchoring rod is provided in the first movable holes. One end of the mounting base plate has a first mating part, and the other end has a second mating part that cooperates with the first mating part.
[0007] Furthermore, the elastic clamping plate includes a guide rod movably disposed in the second movable hole, a first limiting piece is provided at the top of the guide rod, a clamping plate is provided at the bottom of the guide rod, and an abutment spring is provided between the clamping plate and the wing plate.
[0008] Furthermore, an embedded groove is provided on the bottom wall of the clamping groove directly below the clamping plate, and a guide groove is provided on the side wall of the clamping groove.
[0009] Furthermore, a slider is provided on one side of the clamping plate located in the guide groove, and the slider is slidably disposed in the guide groove.
[0010] Furthermore, the anchor rod includes a drill rod, the top of which is provided with a hinge portion, which is disposed in the first movable hole, and the top of the hinge portion is provided with a connector.
[0011] Furthermore, a mating ring is welded to the top of the connector.
[0012] Furthermore, the hinge portion includes a top plate located above, below which are three second limiting plates, and below which are abutment plates.
[0013] Furthermore, the top of the first movable hole is provided with a mounting groove for accommodating the top plate, and the inner sidewall of the first movable hole is provided with a side groove for accommodating three second limiting pieces. The top plate is located below the mounting base plate.
[0014] Furthermore, the first mating part includes a male mating head disposed at one end of the mounting base plate. Slots are provided on both outer sides of the male mating head, and a threaded hole is provided at the top center of each slot on the top of the male mating head. A hand screw is disposed in the threaded hole.
[0015] Furthermore, the second mating portion includes two insert plates on the mounting base away from the first mating portion. A positioning hole is provided at the top center of the insert plate. The insert plate is fully inserted into the slot. The positioning hole is coaxial with the threaded hole.
[0016] The beneficial effects of this invention are as follows: The anchor rod's rotary drilling function embeds itself into the highly weathered sandstone layer, avoiding excessive damage to the slope; the clamping assembly utilizes a spring-driven elastic clamping plate, and the arc-shaped clamping surface formed by the embedded groove and the clamping plate increases the contact area of the non-woven fabric. Combined with the guide groove's slider limiting structure, this ensures clamping stability and prevents penetration damage; the first and second docking parts are connected by slots and insert plates, combined with the quick tightening of hand-tightened screws, enabling the lateral splicing of multiple devices to form an integrated reinforcement network. Compared to traditional steel rod fixing methods, the anchor rod's rotary drilling adapts to highly weathered sandstone geology, improving fixing reliability and avoiding difficulties in steel rod insertion and secondary slope damage; the elastic clamping prevents penetration damage to the non-woven fabric, extends the number of cycles, and reduces construction costs.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0026] like Figure 1-5As shown, this utility model provides a reinforcement device for planting grass and hanging nets on roadbed slopes, including a mounting base plate 10. The top of the mounting base plate 10 is provided with a clamping groove 11. A clamping assembly 20 is provided on the opposite side of the top of the two clamping grooves 11. The clamping assembly 20 includes a wing plate 21 provided on the top side of the clamping groove 11. The top of the wing plate 21 is provided with a second movable hole 2101. An elastic clamping plate 22 is provided in the second movable hole 2101. The top two ends of the mounting base plate 10 are provided with first movable holes 14. An anchoring rod 30 is provided in the first movable holes 14. A first docking part 15 is provided at one end of the mounting base plate 10, and a second docking part 16 that cooperates with the first docking part 15 is provided at the other end.
[0027] In this embodiment, the elastic clamping plate 22 includes a guide rod 2201 movably disposed in the second movable hole 2101. A first limiting piece 2203 is disposed at the top of the guide rod 2201, and a clamping plate 2202 is disposed at the bottom end of the guide rod 2201. An abutment spring 2204 is disposed between the clamping plate 2202 and the wing plate 21. An embedded groove 12 is provided on the bottom wall of the clamping groove 11 directly below the clamping plate 2202. A guide groove 13 is provided on the side wall of the clamping groove 11. A slider is disposed on one side of the clamping plate 2202 located in the guide groove 13. The slider is slidably disposed in the guide groove 13. The arc design of the embedded groove 12 and the bottom of the clamping plate 2202 can increase the clamping area of the non-woven fabric. At the same time, the formed clamping concave surface can further improve its clamping stability. The guide groove 13 is used to increase the stability of the clamping plate 2202 during the up and down movement.
[0028] In this embodiment, the anchor rod 30 includes a drill rod 31, and a hinge part 32 is provided at the top of the drill rod 31. The hinge part 32 is disposed in the first movable hole 14, and a connector 33 is provided at the top of the hinge part 32. The size of the connector 33 adopts the size of the drill bit mating part of the existing electric drill, that is, the anchor rod 30 can be quickly fixed by cooperating with the electric drill.
[0029] In another embodiment, a docking ring 34 is welded to the top of the connector 33, that is, manual drilling is achieved by setting a steel pipe in the docking ring 34 as a connecting member for rotational force.
[0030] In this embodiment, the hinge portion 32 includes a top plate 3201 located above, with three second limiting pieces 3202 disposed below it. An abutment plate 3203 is disposed below the second limiting pieces 3202. The top of the first movable hole 14 is provided with a mounting groove for accommodating the top plate 3201, and the inner sidewall of the first movable hole 14 is provided with a side groove for accommodating the three second limiting pieces 3202. That is, through the interaction between the side groove and the second limiting pieces 3202, the anchor rod 30 is movably disposed in the first movable hole 14. The top plate 3201 is located below the mounting base plate 10 and is used to limit the maximum drilling depth to avoid over-drilling.
[0031] In this embodiment, as Figure 2 As shown, the first docking part 15 includes a male docking head 1501 disposed at one end of the mounting base plate 10. Slots 1502 are provided on both sides of the outer side of the male docking head 1501. A threaded hole 1503 is provided at the top center of each slot 1502 on the top of the male docking head 1501. A hand screw 1504 is disposed in the threaded hole 1503.
[0032] Furthermore, the second docking part 16 includes two insert plates 1601 on the mounting base plate 10 away from the first docking part 15. A positioning hole 1602 is provided at the top center of the insert plate 1601. The insert plate 1601 is fully inserted into the slot 1502. The positioning hole 1602 is coaxial with the threaded hole 1503.
[0033] That is, two mounting base plates 10 form a group. When they need to be used together, the first mating part 15 and the second mating part 16 of any two groups of mounting base plates 10 cooperate with each other so that the opposing insert plates 1601 are inserted into the slots 1502, and then tightened and fixed by hand screws 1504.
[0034] Examples, such as Figure 5 As shown, the mounting base plate 10 is placed at the target position. Using an electric drill or steel pipe, the anchor rod 30 is rotated into the weathered rock layer until the bottom contact plate 3203 contacts the ground, thus completing the installation. The edge of the non-woven fabric is then pulled into the clamping groove 11, the first limiting plate of the clamping assembly 20 is pulled, and a corner of the non-woven fabric is placed between the inner groove 12 and the clamping plate 2202. Through the elastic force of the contact spring 2204, the clamping plate 2202 clamps the non-woven fabric, thus achieving fixation. The above structure solves the problem of poor stability and damage to the non-woven fabric, which reduces the number of times it can be reused, caused by the steel rod insertion fixation method in the strong weathered rock geological environment in the prior art.
[0035] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
