Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection block structures, and in particular to an L-shaped slope protection arch self-locking block. Background Technology
[0002] As a core component of slope protection in transportation and water conservancy projects, slope protection blocks play a crucial role in resisting erosion and damage from the natural environment, thus building a solid defense for project safety and ecological stability. Along highways, railways, and around rivers and reservoirs, slopes often face multiple challenges, including excessive rainfall leading to erosion and extreme temperature fluctuations between winter and summer. These factors can easily cause soil erosion and loosening, and in severe cases, slope collapse, threatening not only the safety of the main structure but also potentially disrupting the surrounding ecological balance. However, current slope protection blocks on the market have significant technical shortcomings. Their fixing and connection methods are relatively simple, and the bottom often uses a planar structure design, relying primarily on concrete for installation. This traditional connection method has strict requirements on ambient temperature. Because concrete is a rigid material, the resulting connection structure lacks elastic buffer space, and when encountering drastic temperature changes, the blocks will expand and contract with temperature fluctuations. Rigid fixing cannot adapt to such volumetric deformation, and the stress between the bricks cannot be effectively released. Over time, this easily leads to problems such as splicing misalignment and widening gaps, ultimately causing the slope protection structure to become unstable and collapse. This severely affects the protective effect and the service life of the project, making it difficult to meet the long-term protection needs in complex environments. Therefore, it is necessary to develop an L-shaped slope protection arch self-locking block to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide an L-shaped slope protection arch self-locking block to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An L-shaped slope protection arch self-locking block includes an integrally set placement base plate and a vertical connecting plate. The lower end of the vertical connecting plate is connected to the rear end of the placement base plate. The lower end of the placement base plate is provided with multiple sets of anti-slip protrusions. The left and right sides of the vertical connecting plate are respectively provided with splicing protrusions and splicing grooves. The splicing protrusions are vertically set and correspond to the rear side of the vertical connecting plate. The splicing grooves are vertically set and correspond to the rear side of the vertical connecting plate. The shapes of the splicing protrusions and splicing grooves are matched.
[0006] Further description of this utility model: the anti-slip protrusions are arranged along the left-right direction along their length, and multiple sets of anti-slip protrusions are arranged along the front-back direction.
[0007] Further description of the present invention: The anti-slip protrusion is trapezoidal in shape with a smaller upper end, and the upper end of the anti-slip protrusion is connected to the base plate.
[0008] Further description of the present invention: The upper end of the anti-slip boss is provided with a first rounded corner on both the front and rear sides, and the lower end of the anti-slip boss is provided with a second rounded corner on both the front and rear sides.
[0009] Further description of the present invention: an anti-slip groove is formed between two sets of adjacent anti-slip protrusions, and the anti-slip protrusion of one set of L-shaped slope protection arch self-locking blocks can be inserted into the anti-slip groove of another set of L-shaped slope protection arch self-locking blocks.
[0010] Further description of the present invention: A first buffer slope is provided on the front side of the splicing boss, the outer end of the first buffer slope transitions to the end face of the splicing boss with a rounded corner, the inner end of the first buffer slope is inclined forward and connected to the end face of the vertical connecting plate, and a second buffer slope is provided on the front side of the splicing groove, the shape of the second buffer slope matching that of the first buffer slope.
[0011] The beneficial effects of this utility model are as follows: It adopts a new mortise and tenon structure, and abandons the flat structure at the bottom to adopt a concave-convex structure, which is a great improvement in structure compared with the previous slope protection blocks. The previous slope protection blocks were only connected and fixed by cast-in-place concrete, which made the structure relatively fragile. Moreover, the connection with the slope surface was not subjected to much force, and it was very easy to misalign or even collapse. However, this utility model relies on the mortise and tenon connection and the concave-convex structure of the bottom of the brick contacting the slope surface, as well as its unique placement method, to increase the force between the brick and the brick, while also giving the whole a force inclined to the bottom of the slope, which enhances its stability and further improves its anti-slip ability. At the same time, after the construction is completed, all the slope protection blocks become a whole, which further enhances the overall stability. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] like Figures 1 to 4 As shown, an L-shaped slope protection arch self-locking block includes an integrally formed placement base plate 1 and a vertical connecting plate 2. The lower end of the vertical connecting plate 2 is connected to the rear end of the placement base plate 1. The lower end of the placement base plate 1 is provided with multiple sets of anti-slip protrusions 11. The left and right sides of the vertical connecting plate 2 are respectively provided with splicing protrusions 21 and splicing grooves 22. The splicing protrusions 21 are vertically arranged and correspond to the rear side of the vertical connecting plate 2. The splicing grooves 22 are vertically arranged and correspond to the rear side of the vertical connecting plate 2. The shapes of the splicing protrusions 21 and the splicing grooves 22 are matched.
[0020] like Figure 4 As shown, multiple sets of slope protection blocks are arranged in a V-shape. The base plate 1 of the slope protection blocks is placed on the slope, and the surface of the base plate 1 is a drainage area. The anti-slip protrusions 11 in contact with the slope surface exert force on the slope surface. At the same time, the splicing protrusions 21 and splicing grooves 22 are mortise and tenon structures. The combination of these two parts ensures that the slope protection blocks will not be misaligned or collapse down the slope, effectively preventing soil erosion. When combined with other slope protection blocks for overall construction, the L-shaped self-locking blocks on both sides also make the overall structure more stable. Placing these slope protection blocks in layers on the slope can more effectively intercept rainwater and further prevent natural disasters such as slope collapse caused by rainwater erosion. Because the splicing protrusions 21 and splicing grooves 22 are mortise and tenon structures, the placed slope protection blocks become a whole, preventing the phenomenon of individual slope protection blocks being misaligned and causing the whole structure to collapse. The advantage of this design lies in its use of a novel mortise and tenon structure. The bottom abandons the planar structure and adopts a concave-convex structure, representing a significant structural improvement over previous slope protection blocks. Traditional slope protection blocks are simply connected and fixed with cast-in-place concrete, resulting in a relatively fragile structure. Furthermore, the connection between the blocks and the slope surface experiences minimal stress, making them prone to misalignment or even collapse. This new design, however, utilizes mortise and tenon connections and a concave-convex structure where the bottom of the brick contacts the slope surface, along with its unique placement method. This increases the force between the brick and the slope surface while simultaneously creating an overall force directed towards the bottom of the slope, enhancing stability and further improving anti-slip capabilities. Moreover, after construction, all the slope protection blocks become a unified whole, further enhancing overall stability.
[0021] The anti-slip protrusions 11 are arranged along the left-right direction along their length, and multiple sets of anti-slip protrusions 11 are arranged along the front-back direction. This allows for a greater interaction force between the anti-slip protrusions 11 and the slope surface, thus improving the anti-slip effect.
[0022] The anti-slip protrusion 11 is trapezoidal in shape with a smaller upper end, and the upper end of the anti-slip protrusion 11 is connected to the base plate 1. The anti-slip protrusion 11 is set as a trapezoidal platform. After construction, the space between the trapezoidal platforms is filled with sloping soil or concrete, which interlocks with the anti-slip protrusion 11, making it difficult for the anti-slip protrusion 11 to detach from the slope.
[0023] The anti-slip protrusion 11 has a first rounded corner 111 on both the front and rear sides of its upper end, and a second rounded corner 112 on both the front and rear sides of its lower end. This reduces stress concentration on the slope protection blocks, prevents cracking, and improves service life.
[0024] The two sets of adjacent anti-slip protrusions 11 form an anti-slip groove 12, and the anti-slip protrusions 11 of one set of L-shaped slope protection arch self-locking blocks can be inserted into the anti-slip groove 12 of another set of L-shaped slope protection arch self-locking blocks. This allows the slope protection blocks to be tightly interlocked during transportation, reducing the space occupied and minimizing collisions.
[0025] The front side of the splicing boss 21 is provided with a first buffer slope 211. The outer end of the first buffer slope 211 transitions to the end face of the splicing boss 21 with a rounded corner. The inner end of the first buffer slope 211 is inclined forward and connected to the end face of the vertical connecting plate 2. The front side of the splicing groove 22 is provided with a second buffer slope 221. The shape of the second buffer slope 221 matches that of the first buffer slope 211.
[0026] When the slope protection blocks expand in summer, the gap between the splicing protrusion 21 and the splicing groove 22 can provide buffer space for adjacent slope protection blocks to avoid compression and cracking. At the same time, the first buffer slope 211 and the second buffer slope 221 cooperate to allow the slope protection blocks to buffer a certain distance along the slope direction.
[0027] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
