Description

Technical Field

[0001] This utility model belongs to the field of road cutting construction technology, specifically a road cutting high slope anchoring structure. Background Technology

[0002] High slopes refer to areas where the height of soil slopes is greater than 20m but less than 100m, or where the height of rock slopes is greater than 30m but less than 100m. Construction safety is of paramount importance for these types of slopes because instability could lead to serious safety accidents. During construction, anchoring structures are usually installed to prevent slope deformation.

[0003] Meanwhile, an anchoring structure for a high road cut slope with application number CN202121088583.X includes a grass grid beam, an anchor cable, and an anchor head. One end of the anchor cable extends into a borehole in the slope, and the other end passes through a through hole in the grass grid beam on the slope and is fixedly connected to the anchor head. The anchor cable includes a grouting pipe, multiple steel strands, a secondary grouting pipe, multiple central circular plate frames, and multiple hoop rings. The central circular plate frames are used to place the grouting pipe in the center of the borehole in the slope, and the hoop rings are wrapped around the periphery of the multiple steel strands to bind the grouting pipe and the steel strands together. This patent uses anchor cables to fix the grass grid beams laid on the slope, making the grass grid beams more stable. Because a central circular plate frame is added to the anchor cable, it not only keeps the anchor cable in the center during drilling, but also limits the position of the secondary grouting pipe. Because the steel strand is surrounded by a protective sleeve, it protects the steel strand and ensures that the steel strand is separated from water, making it less prone to rust and oxidation.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing device can prevent slope deformation, it cannot ensure that the anchor rods used for anchoring remain stable during grouting, resulting in poor grouting effect. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an anchoring structure for high slopes in road cuts, which has the advantage of ensuring the stability of multiple first anchor rods during grouting, resulting in better grouting effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anchoring structure for high slopes in road cuts, comprising a grass paver and multiple first anchor holes and second anchor holes arranged side by side on the top of the grass paver. A first anchor rod is inserted into the inner side of the first anchor hole. A support plate supporting the top of the grass paver is integrally formed on the top of the first anchor rod, and an anchor head is integrally formed on the top of the support plate. A reinforcement hole is constructed on the upper part of the side wall of the anchor head. Reinforcing screws are screwed between the multiple reinforcement holes. Two fixing bolts are symmetrically screwed between the support plate and the top of the grass paver. A second anchor rod is inserted into the second anchor hole. A support plate supporting the top of the grass paver is welded to the top of the second anchor rod, and a U-shaped plate is welded to the top of the support plate.

[0007] Preferably, the first anchor rod and the support plate, and the support plate and the anchor head are both integrally formed by die casting.

[0008] Preferably, a reinforcing plate is connected to the front side of the grass paver, and multiple third anchor rods are inserted side by side at the top of the reinforcing plate.

[0009] Preferably, the top of the support plate and the top of the grass grid are symmetrically provided with two fixing holes, and the fixing bolts are screwed between the corresponding fixing holes.

[0010] Preferably, the support plate has two symmetrical grouting holes on its top, and the grouting holes are located above the first anchor hole.

[0011] Preferably, a baffle is connected to the rear side of the grass paver, and the baffle is perpendicular to the reinforcing plate.

[0012] Preferably, the side wall of the reinforcing screw is fitted with a washer, and the washer is supported between the head of the reinforcing screw and the corresponding anchor head.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses two fixing bolts to reinforce each anchored first anchor rod, and the top of multiple first anchor rods is reinforced by reinforcing screws. The above structure works together to ensure that the multiple anchored first anchor rods remain stable, thus improving the grouting effect during grouting.

[0015] 2. This utility model allows for manual fine-tuning of the position of the second anchor rod via a U-shaped plate, thereby adjusting the gap between the side wall of the second anchor rod and the inner wall of the borehole, resulting in a better grouting effect when grouting is performed through the second anchor hole.

[0016] 3. This utility model increases the stability of the anchoring by using multiple second anchor rods for anchoring, and the second anchor rods can also be reinforced by grouting. With the addition of multiple third anchor rods on the front side for further reinforcement, the stability of the grass grid anchoring is even higher. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides an anchoring structure for a high slope in a road cut, including a grass grid 1 and multiple first anchor holes and second anchor holes 8 arranged side by side on the top of the grass grid 1. Holes are pre-drilled on the high slope corresponding to the first anchor holes and second anchor holes 8. A first anchor rod 2 is inserted into the inner side of each first anchor hole and anchored within the corresponding drilled hole. A support plate 3 is integrally formed on the top of the first anchor rod 2, supporting the top of the grass grid 1. An anchor head 5 is integrally formed on the top of the support plate 3. Reinforcement holes are constructed on the upper side wall of the anchor head 5. Reinforcement screws 6 are screwed between the multiple reinforcement holes. This structure can reinforce multiple first anchor rods 2, preventing the first anchor rods 2 from being damaged during drilling. The hole is deflected to ensure the quality of grouting. Two fixing bolts 7 are symmetrically screwed between the top of the support plate 3 and the top of the grass grid 1. The two fixing bolts 7 can further reinforce the first anchor rod 2 and keep it stable during grouting. The second anchor rod 9 is inserted into the second anchor hole 8. The first anchor rod 9 is anchored in the corresponding drill hole. The top of the second anchor rod 9 is welded with a support plate 10 that supports the top of the grass grid 1. The top of the support plate 10 is welded with a U-shaped plate 11. By holding the U-shaped plate 11, the position of the second anchor rod 9 can be finely adjusted so that its side wall is kept at a reasonable distance from the inner wall of the drill hole. The corners of the U-shaped plate 11 are rounded to improve the grip.

[0023] Specifically, the first anchor rod 2 and the support plate 3, and the support plate 3 and the anchor head 5 are both die-cast integral structures. The die-cast integral structure has high structural strength, is not easy to deform, break or be damaged, and is durable.

[0024] Furthermore, a reinforcing plate 12 is connected to the front side of the grass paver 1. Multiple third anchor rods 13 are inserted side by side on the top of the reinforcing plate 12. The reinforcing plate 12 is laid on the flat ground surface and then reinforced by multiple third anchor rods 13 to increase the overall anchoring stability. No grouting is required at the third anchor rods 13.

[0025] Furthermore, two fixing holes are symmetrically opened on the top of the support plate 3 and the top of the grass grid 1, and the fixing bolts 7 are screwed between the corresponding fixing holes, so that the two fixing bolts 7 can play a strong fixing role.

[0026] It is worth noting that two grouting holes 4 are symmetrically opened on the top of the support plate 3, and the grouting holes 4 are located above the first anchor hole. The setting of the grouting holes 4 facilitates grouting.

[0027] It is worth noting that a baffle 14 is connected to the rear side of the grass paver 1. The bottom of the baffle 14 is inserted into the ground, and the baffle 14 is perpendicular to the reinforcing plate 12. The baffle 14 can block the gravel or other objects rolling down the high slope and ensure the safety of the top structure of the grass paver 1.

[0028] It is worth mentioning that the side wall of the reinforcing screw 6 is fitted with a washer (not shown in the figure), and the washer is supported between the head of the reinforcing screw 6 and the corresponding anchor head 5, so as to prevent the reinforcing screw 6 from being tightened too much and making it difficult to unscrew.

[0029] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: First, grass pavers 1 are poured on the high slope beside the road cut, and holes corresponding to the first anchor hole and the second anchor hole 8 are pre-drilled. Then, the first anchor rod 2 and the second anchor rod 9 are anchored in sequence. After the first anchor rod 2 is anchored, it is reinforced by fixing bolts 7. The anchor heads 5 at the top of multiple first anchor rods 2 are reinforced by screw-connected reinforcing bolts 6 to ensure that the first anchor rod 2 remains stable during grouting. Then, grouting can be done through the grouting hole 4 to obtain a good grouting effect. When grouting the hole of the second anchor rod 9, the position of the second anchor rod 9 can be finely adjusted by holding the U-shaped plate 11 to maintain a reasonable distance between its side wall and the inner wall of the hole, thereby obtaining a good grouting effect. Then, the reinforcing plate 12 is laid on the flat surface, and then reinforced by multiple third anchor rods 13 to increase the overall anchoring stability. The combination of multiple first anchor rods 2, second anchor rods 9, and third anchor rods 13 makes the grass pavers anchored more stable.
