[0032] Highway slope refers to the slope on both sides of the highway. It is a slope with a certain inclination formed to ensure the stability and safety of the highway. When the highway is being built, when the slope needs to be protected, the commonly used protection method is to use pre-measurement and layout, and use artillery to drill holes on the slope. The drilling positions are all measured in advance, and then anchor rods are placed. Then, a grouting machine is used to fill the holes. After the concrete solidifies, a steel frame is built outside the slope, and then concrete is poured outside the steel frame to protect the slope.

[0033] like Figure 1 As shown, Figure 1 Schematic diagram of an existing slope protection device, in which A is a slope, B is a hole, C is an anchor rod, and D is concrete. The anchor rod C of the existing slope protection device is inserted into the hole B. Since the anchor rod C has no supporting mechanism, the anchor rod C is generally located at the bottom of the hole B. When pouring concrete D, the anchor rod C is located on the side of the concrete D, resulting in that the fixing effect of the anchor rod C will be greatly weakened.

[0034] The present application arranges a first fixing ring and a second fixing ring on the anchor rod that match the inner diameter of the drilled hole, so that the first fixing ring and the second fixing ring support the anchor rod and the anchor rod is located in the middle of the drilled hole. Therefore, after pouring concrete, the anchor rod is located in the middle of the concrete, thereby ensuring the fixing quality of the anchor rod and achieving the purpose of stable reinforcement.

[0035] The specific structure of the highway roadbed slope support reinforcement device provided in this application is described in detail below in conjunction with the accompanying drawings.

A plurality of second connecting rods 15 are arranged between the anchor rod 11 and the second fixing ring 13. The first connecting rod 14 and the second connecting rod 15 can both be metal connecting rods. The anchor rod 11, the first connecting rod 14, the second connecting rod 15, the first fixing ring 12 and the second fixing ring 13 can be welded as a whole, and the anchor rod 11, the first fixing ring 12 and the second fixing ring 13 are coaxial. The right end of the anchor rod 11 extends out of the borehole and is connected to the frame assembly 20.

[0038] When reinforcing the roadbed slope, the left end of the anchor rod 11 is inserted into the drill hole, the first fixing ring 12 and the second fixing ring 13 are both inserted into the drill hole, and the outer walls of the first fixing ring 12 and the second fixing ring 13 are both in contact with the hole wall of the drill hole, thereby supporting the anchor rod 11 and fixing the anchor rod 11 in the middle of the drill hole; after pouring concrete, the anchor rod 11 is in the center of the concrete, thereby ensuring the fixing quality of the anchor rod and achieving the purpose of stable reinforcement.

[0039] Reference Figure 3 and Figure 4 As shown, in some embodiments, the reinforcement assembly 10 further includes a guide plate 16, and the guide plate 16 may be a metal plate body with a smooth exterior;

The guide plates 16 can be arc-shaped plates, and the left end of the guide plates 16 is narrow and the right end is wide, so that the geometric body formed by the multiple guide plates 16 is closer to a cone.

[0041] When the reinforcement assembly 10 is inserted into the drill hole, the outer wall of the guide plate 16 is slidably connected to the wall of the drill hole to serve the purpose of guidance, thereby facilitating the stable insertion of the anchor rod 11 into the drill hole.

[0042] In some embodiments, the reinforcement assembly 10 further includes a threaded sleeve 17 and an enlarged plate 18 disposed at the end of the threaded sleeve 17;

[0043] The threaded sleeve 17 is a metal tube body with internal threads. The left end of the threaded sleeve 17 is an open end. The right end of the anchor rod 11 is screwed to the inner wall of the threaded sleeve 17. The enlarged plate 18 can be a metal plate body. The enlarged plate 18 is located in the frame assembly 20 to ensure that the reinforcement assembly 10 is tightly connected to the frame assembly 20 to achieve the purpose of stable reinforcement.

[0044] Reference Figure 5 and Figure 6 As shown, in some embodiments, the frame assembly 20 includes a steel frame 21, which is made of metal welding, and the steel frame 21 is rectangular as a whole, and its upper part is arc-shaped;

[0045] A planting area is formed inside the steel frame 21 for planting green plants to serve a protective purpose. The outer wall of the steel frame 21 is cast with a first concrete 22.

[0046] In some embodiments, the right end of the anchor rod 11 is hinged to the enlarged plate 18 through a connecting piece, and the connecting piece can be a conventional hinged piece, so that the angle between the enlarged plate 18 and the anchor rod 11 can be adjusted, thereby meeting the requirements for slope reinforcement of various slopes;

[0047] The right end of the anchor rod 11 , the connecting piece and the enlarged plate 18 are all fixed in the first concrete 22 , thereby ensuring that the reinforcement assembly 10 and the frame assembly 20 are tightly connected.

[0048] In some embodiments, the frame assembly 20 further includes a reinforcement steel frame 23;

[0049] The reinforcement steel frame 23 is fixed in the steel frame 21 . A plurality of reinforcement steel frames 23 may be arranged in the steel frame 21 . The plurality of reinforcement steel frames 23 divide the planting area into a plurality of sub-areas, thereby improving the strength of the reinforcement steel frames 23 .

[0050] In some embodiments, the reinforcement steel frame 23 may be a trough plate, the upper surface of the trough plate is an open end, and the second concrete 24 is poured in the reinforcement steel frame 23 .

[0051] Reference Figure 5 and Figure 6 As shown, in some embodiments, the reinforcement steel frame 23 is arranged in an arc shape, and the protrusion direction of the arc-shaped reinforcement steel frame 23 is upward.

[0052] In some embodiments, the upper outer wall of the reinforcement steel frame 23 is provided with a first protective mesh plate 25, which may be a metal mesh plate, and the end of the first protective mesh plate 25 is connected to the inner wall of the reinforcement frame 21, and the reinforcement steel frame 23, the first protective mesh plate 25 and the lower surface of the reinforcement steel frame 21 are parallel;

[0054] In the exposed planting area of ​​the steel frame, green plants are generally planted for protection purposes. In the early stage of slope protection, the exposed planting area is still soil. Once heavy rain occurs before the green plants grow, the rainwater gathers and flows. At this time, the soil in the planting area above the reinforced steel frame 23 is easily washed away, causing soil loss and local collapse, which in turn affects the quality of slope protection. The device sets a first protective mesh plate 25 to cover the outside of the soil, and sets a second protective mesh plate 26 on the bottom side of the steel frame 21. At this time, multiple groups of protective mesh plates can play a certain role in preventing soil loss, and the overall frame assembly 20 is set at an angle, which can match the slope at this time for stable protection purposes.

[0055] The highway roadbed slope support and reinforcement device provided by the present application is provided with a first fixing ring 12 and a second fixing ring 13 on an anchor rod 11, the outer diameters of the first fixing ring 12 and the second fixing ring 13 are matched with the inner diameter of the borehole, the anchor rod 11 passes through the first fixing ring 12 and the second fixing ring 13, and the anchor rod 11, the first fixing ring 12 and the second fixing ring 13 are coaxial, and when the anchor rod 11 is inserted into the borehole, the outer walls of the first fixing ring 12 and the second fixing ring 13 are fitted with the wall of the borehole, so that the anchor rod 11 is stably located in the middle of the borehole. After pouring concrete, the anchor rod 11 is located in the center of the concrete, thereby ensuring the fixing quality of the anchor rod and achieving the purpose of stable reinforcement.
