Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, and particularly relates to a road slope structure for preventing landslides. Background Art

[0002] As an important part of a highway, the stability of a highway slope is directly related to the safety and service life of the highway. Especially in areas with complex geological conditions and frequent rainfall, highway slopes are prone to geological disasters such as landslides and collapses.

[0003] Currently, there are already devices on the market for preventing landslides on highway slopes. Referring to a slope anti-slip device disclosed in a Chinese utility model patent with the patent application number 2022214276252, which includes a top catchment ditch, a linear drainage ditch, an impact-resistant blanket, a geotechnical soil-retaining compartment, and fixed piles; a permeable grid cover plate is arranged on the top surfaces of the top catchment ditch and the linear drainage ditch. The top catchment ditch is installed at the top of the slope. One end of the linear drainage ditch is hermetically connected through an opening on the side of the top catchment ditch. The linear drainage ditch is inclined along the slope surface. The impact-resistant blanket is covered on the slope surface, and a geotechnical soil-retaining compartment is arranged above the impact-resistant blanket through fixed piles. This structure has a geotechnical soil-retaining compartment arranged above the impact-resistant blanket through fixed piles, which plays a role in fixing the linear drainage ditch and the impact-resistant blanket, and also further performs anti-landslide treatment on the soil on the slope surface, reducing the cost of the anti-slip roadbed and improving the soil environment.

[0004] However, this method of covering the slope surface with an impact-resistant blanket still has deficiencies in the soil-fixing effect. The impact-resistant blanket can only perform anti-slip reinforcement on the soil layer on the slope surface, and cannot effectively prevent landslides on deeper soil layers. Therefore, landslides may still occur. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a road slope structure for preventing landslides.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0007] A road slope structure for preventing landslides includes a plurality of slope-fixing plates that can be spliced with each other. The slope-fixing plate includes a rectangular frame, a fixed ring seat located in the middle of the frame, and a support rod connected between the fixed ring seat and the frame. An assembly hole is provided in the middle of the fixed ring seat. A fixed column is fitted in the assembly hole. An insertion rod for inserting into the soil slope is provided at the bottom of the assembly hole. After the insertion rod is inserted into the soil slope, it is embedded into the soil for slope fixation through the pressing cooperation of the fixed column; connection structures for splicing between multiple slope-fixing plates are provided at the four corners of the frame, and multiple slope-fixing plates are sequentially spliced through the connection structures.

[0008] In the present utility model, connection seats are respectively provided at four corners of the frame, the connection structure is arranged on the connection seats, the connection structure includes a clamping groove arranged on the connection seats and a clamping buckle protruding outside the connection seats, and the relative positions of the clamping groove and the clamping buckle on each connection seat are the same.

The support rods extend obliquely upward from the connection seats to the fixed ring seat, and the fixed ring seat protrudes from the top surface of the frame.

[0010] In the present utility model, there are multiple groups of insertion rods, and the multiple groups of insertion rods are circumferentially distributed around the assembly hole. Under normal conditions, the insertion rods contract inwardly towards the assembly hole from top to bottom, and an inverted buckle structure extending outward is further provided at the bottom of the insertion rods. When the fixed column is inserted into the assembly hole from top to bottom, the insertion rods are gradually pushed outward to embed the inverted buckle structure into the soil.

[0011] Further, an internal thread structure is provided on the inner side of the assembly hole, an external thread structure is provided on the outer side of the fixed column, and after the fixed column is inserted into the assembly hole, fastening is achieved through the cooperation of the external thread structure and the internal thread structure.

[0024] Such as Figures 1 to 4As shown in the figure, this embodiment discloses a road slope structure for preventing landslides, which includes a number of slope-fixing plates 1 that can be spliced with each other. The slope-fixing plates 1 are made of plastic material and have a certain deformation ability. The slope-fixing plate 1 includes a frame 11 with a rectangular structure, a fixing ring seat 12 located in the middle of the frame 11, and a support rod 13 connected between the fixing ring seat 12 and the frame 11. An assembly hole 120 is provided in the middle of the fixing ring seat 12, a fixing column 14 is fitted in the assembly hole 120, and a plug rod 121 for inserting into the soil slope is further provided at the bottom of the assembly hole 120. After the plug rod 121 is inserted into the soil slope, it is embedded into the soil for slope fixation through the pressing fit of the fixing column 14; connection structures 15 for splicing between multiple slope-fixing plates 1 are provided at the four corners of the frame 11. After multiple slope-fixing plates 1 are sequentially spliced through the connection structures 15, they are embedded on the road slope to prevent landslides.

[0025] In this structure, a fixing ring seat 12 is arranged in the middle of the frame 11. A plug rod 121 is provided at the bottom of the fixing ring seat 12 and inserted into the soil slope, and the plug rod 121 is deeply embedded into the soil by cooperating with the fixing column 14, improving the firmness of the deep soil, thereby improving the slope fixation effect; at the same time, connection structures 15 are arranged at the four corners of the frame 11, enabling the slope-fixing plates 1 to be spliced one by one. The operation method is simple and the installation is convenient.

[0026] In this embodiment, connection seats 150 are respectively arranged at the four corners of the frame 11, and the connection structure 15 is arranged on the connection seats 150. The connection structure 15 includes a card slot 151 arranged on the connection seat 150 and a buckle 152 protruding outside the connection seat 150. It can be determined that the card slot 151 and the buckle 152 on each connection seat 150 are arranged at corresponding positions, thus facilitating splicing. When installing the slope-fixing plate 1 on the road slope, there is no need to distinguish the installation direction, and it can be directly installed in place, improving the installation efficiency.

[0027] Furthermore, four support rods 13 are provided. One ends of the four support rods 13 are respectively connected to the connection seats 150, and the other ends are commonly connected to the outside of the fixing ring seat 12. Preferably, the support rods 13 extend obliquely upward from the connection seats 150 to the fixing ring seat 12, so that the fixing ring seat 12 protrudes from the top surface of the frame 11. In this way, a gap can be formed below the support rods 13, and vegetation can be planted in the gap, which can not only improve the soil environment but also enhance the aesthetic degree.

[0028] In this embodiment, there are multiple groups of the insertion rods 121, and the multiple groups of insertion rods 121 are circumferentially distributed around the assembly hole 120. Under normal conditions, the insertion rods 121 contract inwardly towards the assembly hole 120 from top to bottom. At the same time, an inverted buckle structure 122 extending outward is provided at the bottom of the insertion rods 121. When the fixing column 14 is inserted into the assembly hole 120 from top to bottom, the insertion rods 121 are gradually pushed outward, so that the inverted buckle structure 122 is embedded in the soil. This can not only improve the firmness of the soil, but also improve the stability of the slope protection plate 1 and prevent loosening.

[0029] Furthermore, an internal thread 123 structure is provided at a position near the top inside the assembly hole 120, and an external thread structure 140 is also provided at a position near the top outside the fixing column 14. After the fixing column 14 is inserted into the assembly hole 120, the external thread structure 140 cooperates with the internal thread 123 structure to achieve fastening, preventing the fixing column 14 from being easily pulled out.

[0030] Furthermore, a limit cap 141 is provided at the top of the fixing column 14. When the fixing column 14 is fully fitted in the assembly hole 120, the limit cap 141 abuts against the top of the fixing ring seat 12. In addition, an anti-slip groove 142 for facilitating the rotation of the fixing column 14 is provided at the top of the limit cap 141. When the fixing column 14 is inserted into the assembly hole 120, it will be subject to the resistance of the insertion rods 121, and the rotation method can play a role in saving effort and is convenient for installation.

[0031] In this embodiment, slope protection structures are provided at the bottoms of the frame 11 and the connecting seat 150. The slope protection structure at the bottom of the frame 11 extends along the length direction to form a slope protection piece 111, and the slope protection structure at the bottom of the connecting seat 150 extends downward to form a conical slope protection rod 112. The slope protection piece 111 and the slope protection rod 112 can reinforce the shallow soil and improve the slope protection effect.

[0032] What is described above in this specification is only an example of the present invention. Those skilled in the technical field to which the present invention belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present invention or exceed the scope defined by this claims, they should all belong to the protection scope of the present invention.
