Description

Technical Field

[0001] This utility model relates to a slope protection device, and more particularly to a prefabricated slope protection device, belonging to the field of slope protection technology. Background Technology

[0002] In recent years, with the large-scale construction of water conservancy and transportation projects, as well as the exploitation of mineral resources in my country, many exposed slopes have been created, causing significant soil erosion and potential geological hazards, while also exacerbating ecosystem degradation. Slope protection is an important safety measure for slopes, referring to various paving and planting methods used on slopes to prevent erosion. However, due to the increasing scarcity and cost of large natural stone resources, precast concrete blocks are used for paving operations. Precast concrete blocks are generally prefabricated in factories and then transported to the slope construction site for use.

[0003] Ordinary block structures, lacking effective connecting and limiting mechanisms, are often used as independent units in practical applications. This lack of a robust interconnected protection structure makes them prone to displacement under external forces, failing to achieve their intended slope protection function and thus presenting limitations. To address this, interlocking bricks have been proposed. These bricks employ simple interlocking structures, some connecting through gaps between blocks, others through slotted joints, linking multiple blocks together to achieve a slope protection effect.

[0004] While interlocking bricks can be connected into a single unit during assembly, some interlocking bricks can still detach perpendicular to the brick surface when the slope settles or is impacted by river waves, affecting the overall protective effect. Furthermore, the connections between interlocking bricks are not very secure, so turf is often planted on the slope protection structure to improve its effectiveness, enhance aesthetics, and protect the natural landscape. Planting troughs are typically cut into the bricks for planting. If the troughs are too small, the planting space is limited and cannot accommodate small shrubs; sometimes, the turf in the troughs dies for various reasons, and removal is not convenient when replacement is needed. If the troughs are too large, they are unsuitable for rainy conditions with frequent heavy rainfall. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a prefabricated slope protection device.

[0006] The technical solution adopted by this utility model is as follows: a prefabricated slope protection device is designed, which includes prefabricated slope protection bricks and prefabricated connecting bricks. The prefabricated slope protection bricks and prefabricated connecting bricks can be connected and limited between each other and between any two prefabricated slope protection bricks. In use, several prefabricated slope protection bricks and prefabricated connecting bricks are assembled into a slope protection structure covering the slope surface. In the slope protection structure, four adjacent prefabricated slope protection bricks form a limiting groove, and a prefabricated connecting brick is placed in the limiting groove. The prefabricated connecting brick limits the lateral movement of the prefabricated slope protection brick connected to it. Limiting structures are respectively set at the left and right ends of the prefabricated slope protection bricks. In the slope protection structure, the prefabricated slope protection bricks arranged in a horizontal row are fastened to each other through the limiting structures to limit the movement of the prefabricated slope protection bricks in the vertical and horizontal directions and the front and back directions. A planting mother groove is set in the middle of the prefabricated slope protection bricks. An adjusting block is inserted in the planting mother groove, and multiple planting sub-grooves are set in the adjusting block.

[0007] Furthermore, the precast slope protection bricks adopt a cross-shaped structure, with limiting shoulders set on the upper and lower sides of the left and right ends respectively. The precast connecting bricks are set in an I-shaped structure. In the slope protection structure, the four limiting shoulders of four adjacent precast slope protection bricks are locked in the belly of the precast connecting bricks.

[0008] Furthermore, the limiting shoulder adopts a right-angled trapezoidal structure, and the upper and lower sides of the precast connecting brick are provided with isosceles trapezoidal grooves. When the precast slope protection brick is connected to the precast connecting brick, the hypotenuse of the limiting shoulder fits into one side of the hypotenuse of the isosceles trapezoidal groove on one side of the precast connecting brick.

[0009] Furthermore, the limiting structure includes a first step and a second step, which are respectively disposed on opposite sides of the thickness direction of the end of the precast slope protection brick and staggered along the length direction of the end of the precast slope protection brick. When the precast slope protection bricks are fastened together by the limiting structure, the limiting structure of one brick is inserted into the limiting structure of the other brick.

[0010] Furthermore, the planting mother trough is a rectangular trough, the adjusting block is a corresponding rectangular block, and four rectangular planting sub-troughs are set inside the adjusting block.

[0011] Furthermore, the thickness of the adjusting block is less than the depth of the planting mother trough, and when the adjusting block is placed in the planting mother trough, its upper surface is lower than the planting mother trough.

[0012] Furthermore, the front and rear surfaces of the precast slope protection bricks are respectively provided with connecting grooves that communicate with the planting trough. In the slope protection structure, the connecting grooves between adjacent precast slope protection bricks are interconnected.

[0013] Furthermore, the front and rear surfaces of the precast slope protection bricks are respectively arranged with cross-shaped connecting grooves, which penetrate the surface of the precast slope protection bricks from left to right and from top to bottom.

[0014] Furthermore, the limiting groove includes a limiting part and a brick-removing part. The upper and lower sides of the limiting part are respectively provided with brick-removing parts. The limiting part is used to receive the precast connecting brick, and the brick-removing part is used to penetrate into the upper and lower sides of the precast connecting brick to remove the precast connecting brick.

[0015] The present invention has the following advantages:

[0016] This invention, through the design of a limiting structure, ensures that when prefabricated slope protection bricks arranged in horizontal rows are interlocked in pairs during assembly to cover the slope surface. This limiting structure restricts the movement of the prefabricated slope protection bricks in the vertical and forward / backward directions. Furthermore, the use of prefabricated slope protection bricks and prefabricated connecting bricks further restricts their lateral displacement, forming a three-axis limiting structure. Even when the slope experiences minor settlement or wave impact, localized prefabricated slope protection bricks will not disengage in the interlocking state along directions perpendicular to the brick surface, resulting in good overall protection. In addition, the design of planting mother troughs, adjusting blocks, and planting daughter troughs allows for flexible planting of small shrubs and lawns. Planting mother troughs and planting daughter troughs can be used individually or in combination for better slope protection while enhancing aesthetics and protecting the natural landscape. For example, if the opening of the planting trough is too small, limiting the planting space for the desired plants, the adjusting block can be removed, and a larger planting trough can be used to accommodate plants such as small shrubs. Conversely, if the opening of the planting trough is too large and unsuitable for rainy or frequent heavy rainfall conditions, an adjusting block can be inserted, offering flexibility and various options. Furthermore, if the turf in the planting trough becomes necrotic and needs replacement, the adjusting block can be removed first before removal, making the process more convenient. This invention allows for flexible arrangement of planting troughs and plants according to site conditions and environmental factors, maximizing the ecological benefits of the slope protection structure.

[0017] When this utility model is used, any one of the prefabricated slope protection bricks can form a three-axis lock, and the connection method has good stability. The components are not easy to separate. Even if the slope experiences large-area settlement or collapse, the assembled slope protection structure can still play a good protective and support role, making the application scenarios of this application more extensive.

[0018] The precast slope protection bricks and precast connecting bricks of this utility model have simple structures, are easy to connect, and are easy to assemble on the construction site. They can ensure high on-site splicing construction efficiency and have broad application space and promotion value. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-4As shown, a prefabricated slope protection device includes prefabricated slope protection bricks 1 and prefabricated connecting bricks 2. The prefabricated slope protection bricks 1 and prefabricated connecting bricks 2 can be connected and positioned between each other, and between any two prefabricated slope protection bricks 1. The prefabricated slope protection bricks 1 and prefabricated connecting bricks 2 are used together to form a prefabricated slope protection device. In use, several prefabricated slope protection bricks 1 and prefabricated connecting bricks 2 are assembled to form a slope protection structure 3 covering the slope surface to be protected. In the slope protection structure 3, four adjacent prefabricated slope protection bricks 1 form a limiting groove 4. A prefabricated connecting brick 2 is placed in the limiting groove 4. The prefabricated connecting brick 2 limits the lateral movement of the prefabricated slope protection bricks 1 connected to it. That is, the lateral displacement of the four prefabricated slope protection bricks 1 forming the limiting groove 4 is restricted by the prefabricated connecting brick 2 within the limiting groove 4. The precast slope protection bricks 1 are provided with limiting structures 5 at both ends. In the slope protection structure 3, the precast slope protection bricks 1 arranged in a horizontal row are fastened together in pairs by the limiting structures 5 to limit the movement of the precast slope protection bricks 1 in the vertical and horizontal directions and the front and back directions. The precast connecting bricks 2 and the limiting structures 5 form a three-axis (X-axis, Y-axis, Z-axis) limiting for the precast slope protection bricks 1, that is, limiting in three dimensions. A planting mother trough 6 is provided in the middle of the precast slope protection bricks 1. An adjusting block 7 is inserted into the planting mother trough 6, and multiple planting sub-troughs 8 are set in the adjusting block 7. When the adjusting block 7 is not placed in the planting mother trough 6, small shrubs can be planted, while grass and other green plants can be planted in the planting sub-troughs 8. In the same slope protection structure 3, small shrubs and grass can be planted together. In addition, when the grass in the planting sub-trough 8 becomes necrotic, the adjusting block 7 can be removed before cleaning, at which time the trough opening is larger and the removal is convenient.

[0029] Example 2

[0030] This embodiment is a further optimization and refinement of the precast slope protection brick 1 structure based on Embodiment 1, specifically as follows:

[0031] like Figure 2-3 As shown, the precast slope protection brick 1 adopts a cross-shaped structure, that is, it has protruding bosses on its four sides (top, bottom, left, and right). Limiting shoulders 9 are provided on the top and bottom sides of the left and right ends of the precast slope protection brick 1. The precast connecting brick 2 is configured with an I-shaped structure, as shown... Figure 4 As shown, a groove is provided on its abdomen. In the slope protection structure 3, the four adjacent limiting shoulders 9 of the four adjacent prefabricated slope protection bricks 1 are locked in the abdomen of the prefabricated connecting bricks 2, thereby limiting the prefabricated slope protection bricks 1.

[0032] In this embodiment, the limiting shoulder 9 adopts a right-angled trapezoidal structure, and the upper and lower sides of the prefabricated connecting brick 2 are provided with isosceles trapezoidal grooves 10, making the structure more robust. When the prefabricated slope protection brick 1 is connected to the prefabricated connecting brick 2, the hypotenuse of the limiting shoulder 9 fits against one hypotenuse of the isosceles trapezoidal groove 10 on one side of the prefabricated connecting brick 2, making the connection more stable and reliable. It is understood that the limiting shoulder 9 can also adopt other structures, such as a rectangular block structure.

[0033] Example 3

[0034] This embodiment is a further optimization and refinement of the limiting structure 5 based on embodiment 2, specifically as follows:

[0035] The limiting structure 5 includes a first step 11 and a second step 12. The first step 11 and the second step 12 are respectively disposed on opposite sides of the thickness direction of the end of the precast slope protection brick 1, and are staggered along the length direction of the end of the precast slope protection brick 1. When the precast slope protection bricks 1 are fastened together by the limiting structure 5, the limiting structure 5 of one brick is inserted into the limiting structure 5 of the other brick, thereby limiting the precast slope protection brick 1 in the vertical and horizontal directions and the front-back direction (i.e., the direction perpendicular to the surface of the precast slope protection brick 1). The limiting structure 5 can also be a protrusion and a groove respectively disposed at the left and right ends of the precast slope protection brick 1. The protrusion can be inserted into the groove, but this structure is relatively difficult to cast and demold, and the structural strength is also relatively weak.

[0036] Example 4

[0037] This embodiment is a further optimization and refinement of the slope protection device structure based on Embodiment 3, specifically as follows:

[0038] In this embodiment, the prefabricated slope protection device has a rectangular planting trough 6 and a corresponding rectangular adjusting block 7. The adjusting block 7 facilitates the insertion or removal of the planting trough 6. Four rectangular planting sub-troughs 8 are provided within the adjusting block 7, serving both for planting grass seeds and for easy removal of the adjusting block 7. Alternatively, the planting trough 6 can be configured with a circular hole structure, and correspondingly, the adjusting block 7 can be configured as a cylindrical structure.

[0039] In this embodiment, the thickness of the adjusting block 7 is less than the depth of the planting trough 6. When the adjusting block 7 is placed in the planting trough 6, its upper surface is lower than the planting trough 6. When planting grass seeds in the planting sub-troughs 8, each planting sub-trough 8 is filled with soil or nutrient soil. Furthermore, soil is also applied to the planting trough 6 above the adjusting block 7, ensuring the grass seeds are fully covered and providing a good growing environment. Additionally, setting the adjusting block 7 lower than the planting trough 6 also provides a certain water retention effect, facilitating the growth of the planted plants.

[0040] Example 5

[0041] This embodiment is a further optimization and refinement of the precast slope protection brick 1 structure based on embodiment 4, specifically as follows:

[0042] The front and rear surfaces of the precast slope protection bricks 1 are respectively provided with connecting grooves 13 that communicate with the planting troughs 6. In the slope protection structure 3, the connecting grooves 13 between adjacent precast slope protection bricks 1 are interconnected. The connecting grooves 13 can drain water from the surface of the slope protection structure 3 to prevent water accumulation on its surface for a long time and affect its use. On the other hand, they can also facilitate the flow of water between the precast slope protection bricks 1, so that the water content is balanced throughout the slope protection structure 3, thereby ensuring balanced growth of green plants on it.

[0043] In this embodiment, the front and rear surfaces of the prefabricated slope protection brick 1 are respectively arranged with cross-shaped connecting grooves 13. The connecting grooves 13 penetrate the surface of the prefabricated slope protection brick 1 from left to right and from top to bottom. This ensures that water can flow in multiple directions and also makes the prefabricated slope protection brick 1 more versatile.

[0044] In addition, soil can be placed in the connecting groove 13, which allows for better water transfer to the vegetation within the multiple bricks during planting.

[0045] Example 6

[0046] This embodiment is a further optimization and refinement of the structure of the limiting groove 4 based on embodiment 5, specifically as follows:

[0047] The limiting groove 4 includes a limiting part 14 and a brick-taking part 15. The brick-taking part 15 is provided on the upper and lower sides of the limiting part 14, and preferably symmetrically arranged. The limiting part 14 is used to receive the precast connecting brick 2, and the brick-taking part 15 is used to penetrate into the upper and lower sides of the precast connecting brick 2 to take out the precast connecting brick 2, which facilitates the laying operation.

[0048] When using this utility model, the prefabricated slope protection bricks 1, prefabricated connecting bricks 2 and adjusting blocks 7 are laid along the slope surface.

[0049] This utility model can be used to support slopes or sides, ensuring slope stability and preventing soil erosion. It can also be used for planting vegetation to form a comprehensive slope protection system composed of engineering structures and plants, further improving slope stability and making it more aesthetically pleasing.

[0050] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple," "multiple roots," and "multiple groups" mean two or more, and "several," "several roots," and "several groups" mean one or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used only for descriptive purposes and should not be construed as indicating or implying relative importance.

[0051] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
