Description

Technical Field

[0001] This utility model relates to the field of slope protection block structures, and in particular to a U-shaped slope protection arch self-locking block. Background Technology

[0002] Slope protection blocks are core components for slope protection in transportation and water conservancy projects. Their primary function is to effectively protect slopes along roads and rivers, resisting erosion and damage from natural environmental factors. They prevent soil erosion and slope collapse caused by excessive rainfall, and mitigate ecological damage such as soil shrinkage and cracking, and structural instability caused by extreme temperature differences between winter and summer. This provides a fundamental guarantee for the safety of construction projects and the stability of the surrounding ecological environment. Currently, mainstream slope protection blocks on the market have significant technical shortcomings. Their fixing and connection methods are relatively simple, with most using a planar structure design at the bottom, relying mainly on concrete pouring for connection and fixation during installation. This rigid fixing method has extremely poor adaptability to environmental temperature. Because concrete has no elastic buffer space after curing, it cannot cope with the thermal expansion and contraction effects caused by temperature changes. Misalignment and loosening of blocks, and between blocks and the slope base, are very likely to occur. In severe cases, this can lead to the collapse of the entire protective structure, significantly reducing the slope protection effect and failing to meet the long-term protection needs in complex environments. Therefore, it is necessary to develop a U-shaped slope protection arch self-locking block to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a U-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] A U-shaped slope protection arch self-locking block includes an integrally formed anti-slip base plate, a first guide plate, and a second guide plate. The front end of the anti-slip base plate is provided with multiple sets of anti-slip protrusions, which are vertically arranged and gradually increase in cross-section from top to bottom. The upper end of the anti-slip base plate is provided with a splicing protrusion, which is arranged in the left-right direction. The lower end of the anti-slip base plate is provided with a splicing groove, which is arranged in the left-right direction and matches the shape of the splicing groove with the splicing protrusion. The first guide plate and the second guide plate are respectively connected to the left and right sides of the rear end of the anti-slip base plate. The first guide plate, the second guide plate, and the rear end face of the anti-slip base plate enclose a guide channel.

[0006] Further description of the present invention: The anti-slip boss is in the shape of a quadrangular frustum with the upper end being the smaller end.

[0007] Further description of the present invention: The rear left and right sides of the anti-slip boss are provided with first rounded corners, and the front left and right sides of the anti-slip boss are provided with second rounded corners.

[0008] 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 U-shaped slope protection arch self-locking blocks can be inserted into the anti-slip groove of another set of U-shaped slope protection arch self-locking blocks.

[0009] Further description of the present invention: The splicing boss is trapezoidal in shape with the upper end being the smaller end, and the shape of the splicing groove matches the shape of the splicing boss.

[0010] Further description of this utility model: The left and right sides of the rear end face of the anti-slip base plate are rounded to the first guide plate and the second guide plate.

[0011] The beneficial effects of this utility model are as follows: the connection between the slope protection blocks adopts a mortise and tenon structure, and the anti-slip protrusion at the bottom adopts a mortise and tenon structure. This represents a significant improvement in structure compared to previous slope protection blocks. In the past, slope protection blocks were only connected and fixed by cast-in-place concrete, which made the structure relatively fragile and subject to high environmental requirements. This design, however, increases the interaction force between the blocks by using mortise and tenon connections and the mortise and tenon joints at the bottom of the bricks that contact the slope surface. At the same time, the bottom mortise and tenon joints, which are wider at the top and narrower at the bottom, further enhance its stability and improve its anti-slip ability. After construction, all the bricks become a whole, further enhancing the overall stability. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1 to 3As shown, a U-shaped slope protection arch self-locking block includes an integrally formed anti-slip base plate 1, a first guide plate 2, and a second guide plate 3. The front end of the anti-slip base plate 1 is provided with multiple sets of anti-slip protrusions 11, which are vertically arranged and gradually increase in cross-section from top to bottom. The upper end of the anti-slip base plate 1 is provided with a splicing protrusion 12, which is arranged in the left-right direction. The lower end of the anti-slip base plate 1 is provided with a splicing groove 13, which is arranged in the left-right direction and matches the shape of the splicing groove 13 with the splicing protrusion 12. The first guide plate 2 and the second guide plate 3 are respectively connected to the left and right sides of the rear end of the anti-slip base plate 1. The first guide plate 2, the second guide plate 3, and the rear end face of the anti-slip base plate 1 enclose a guide channel 4.

[0019] The slope protection blocks in this design have a flow channel 4 at the rear end and an anti-slip protrusion 11 at the front end. The anti-slip protrusion 11 has a narrow side near the splicing protrusion 12 and a wide side near the splicing groove 13. During construction, the splicing protrusion 12 is placed towards the bottom of the slope and the splicing groove 13 is placed towards the top of the slope. At the same time, the two sets of adjacent slope protection blocks are connected by the splicing protrusion 12 and the splicing groove 13 to form a mortise and tenon structure, which prevents the blocks from being misaligned or even collapsing due to thermal expansion and contraction or heavy rain. After placement, the blocks are connected by mortise and tenon joints. The blocks are fixed to the slope surface by the anti-slip protrusion 11 and the cast-in-place concrete. After construction, it is a whole, and no block can be pulled out independently. The advantages of this design are as follows: the connection between the slope protection blocks adopts a mortise and tenon structure, and the anti-slip protrusion 11 at the bottom adopts a mortise structure. This represents a significant improvement in structure compared to previous slope protection blocks. In the past, slope protection blocks were only connected and fixed by cast-in-place concrete, which made the structure relatively fragile and subject to high environmental requirements. This design, however, increases the interaction force between the blocks by using mortise and tenon connections and the mortise structure at the bottom of the bricks that contacts the slope. At the same time, the bottom mortise structure, which is wider at the top and narrower at the bottom, further enhances its stability and improves its anti-slip ability. After construction, all the bricks become a whole, further enhancing the overall stability.

[0020] The anti-slip protrusion 11 is shaped like a truncated pyramid with a smaller upper end. Setting the anti-slip protrusion 11 as a truncated pyramid satisfies the requirement that the anti-slip protrusion 11 is wider at the top and narrower at the bottom when the blocks are placed, and also facilitates the forming of the anti-slip protrusion 11 during the manufacturing process.

[0021] The anti-slip protrusion 11 has a first rounded corner 111 on both the left and right sides of its rear end, and a second rounded corner 112 on both the left and right sides of its front end. This reduces stress concentration on the slope protection blocks, prevents cracking, and improves service life.

[0022] Two sets of adjacent anti-slip protrusions 11 form an anti-slip groove 14. The anti-slip protrusions 11 of one set of U-shaped slope protection arch self-locking blocks can be inserted into the anti-slip groove 14 of another set of U-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.

[0023] The splicing boss 12 is trapezoidal with a smaller upper end, and the shape of the splicing groove 13 matches the shape of the splicing boss 12. The trapezoidal evaluation boss and the splicing groove 13 have a simple structure and are easy to manufacture.

[0024] The left and right sides of the rear end face of the anti-slip base plate 1 are rounded to the first guide plate 2 and the second guide plate 3. The flow channel 4 is used for water flow. The rounded transition between the anti-slip base plate 1 and the first guide plate 2 and the second guide plate 3 can avoid stress concentration at the joint and improve service life.

[0025] 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.
