Description

Technical Field

[0001] The invention belongs to the field of river ecological slope protection, and relates to an ecological prefabricated slope protection block adaptable to multiple slopes and a splicing and laying method thereof. Background Art

[0002] With the booming construction industry and rapid economic growth, the problem of construction waste has become increasingly severe and has become an environmental challenge that needs to be solved urgently. In order to effectively meet this challenge, prefabricated slope protection, as an innovative means of recycling construction waste, is gradually showing its broad application prospects, and its types are constantly enriching and improving.

[0003] Traditional slope protection is known for its excellent slope protection ability, but unfortunately, its appearance design is often monotonous and difficult to blend harmoniously with the surrounding environment. In addition, traditional slope protection has a significant limitation, that is, it is usually difficult to adapt to complex and changeable terrain and multi-angle slopes. This rigid structure often lacks sufficient flexibility and adaptability when facing slopes with different inclination angles, curved surfaces or irregular shapes, which may lead to increased construction difficulty, poor slope protection effect or increased costs. In contrast, ecological slope protection pays more attention to its own strength, safety and durability, and is committed to building a stable and lasting slope protection system. It aims to achieve ecological restoration and protection of slopes by using vegetation, soil engineering materials and biotechnology. However, the current ecological slope protection still has shortcomings in the connection and fixation between blocks, which makes many slope protection structures prone to slip during long-term use, thereby weakening their slope protection effect. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide an ecological prefabricated slope protection block that is adaptable to multiple slopes and a method for splicing and laying the same. The present invention has a simple and reasonable structure, which not only greatly simplifies the construction process and realizes fast and efficient operation, but also significantly enhances the protective ability of the slope protection and the stability of the overall structure.

[0005] The technical solution of the present invention is: the prefabricated slope protection block adapted to multiple slopes described in the present invention comprises two categories: standard components and special components;

[0006] The standard assembly is composed of a double gear on the top and an 8-shaped base on the bottom;

[0007] The special assembly consists of a single gear on top and a ring-shaped base on the bottom.

[0008] Furthermore, the top body of the double gear is constructed in the form of two regular hexagonal prisms, with a cut-off arc portion at the top corner, a concave ecological hole at the center of the top, and a convex docking column at the bottom.

[0009] Furthermore, the bottom body of the 8-shaped base also includes two regular hexagonal prisms matching the top body, the upper half of which is provided with a through hole, and the lower half is provided with a first leg, a second leg, a third leg, a fourth leg, a fifth leg, and a sixth leg, a total of six legs, and the six legs are formed by hollowing out concave gear pores matching the shape of the upper double gear component;

[0010] The standard components are firmly connected to the 8-shaped base through the docking column passing through the opening;

[0011] The assembly principle of the special assembly is the same, that is, the upper and lower components are separated and then butted together;

[0012] The standard components can be nested in each other up and down, left and right, to construct a staggered stepped or porous ecological slope protection structure, while special components are used for leveling in the edge areas.

[0013] Furthermore, the ecological holes may be filled with ecological concrete, which not only enhances the bonding strength between components but also improves the aesthetics of the slope protection.

[0014] Furthermore, the concave gear holes of the bottom 8-shaped base together with the first leg, the second leg, the third leg, the fourth leg, the fifth leg, and the sixth leg, a total of six legs, can be effectively embedded in the river bank soil, thereby enhancing the overall stability of the slope protection.

[0015] Furthermore, the present invention utilizes gravity and unique structural design to enhance the connection firmness between blocks, and by flexibly adjusting the assembly mode, it is suitable for both steep slopes and gentle slopes. By adjusting the overall size specifications of the components, the present invention can also accurately meet the needs of river slope protection of different slopes.

[0016] Furthermore, a splicing and laying method of ecological prefabricated slope protection blocks suitable for multiple slopes is divided into the following types:

[0017] (1) After the slope surface is leveled, standard components are used for paving, special components are trimmed, pressed into the slope protection soil, and ecological concrete is added to the ecological holes formed after splicing. After curing and forming, alkali reduction and soil covering are carried out;

[0018] (2) Insert two standard components up and down, insert the first leg of the lower base of the upper component into the ecological hole in the upper double gear of the lower component, stack them layer by layer, and pour ecological concrete into the ecological hole after splicing to reduce alkali and plant vegetation. This method is used for rivers with gentle slopes. The specific plan is shown in the attached figure.

[0019] (3) Insert two standard components up and down, insert the second leg of the lower base of the upper component into the ecological hole in the upper double gear of the lower component, stack them layer by layer, and pour ecological concrete into the ecological hole after splicing to reduce alkali and plant vegetation. This method is used for rivers with steeper slopes.

[0020] The beneficial effects of the present invention are as follows: 1. The prefabricated components are made entirely of environmentally friendly fully recycled aggregates, which not only greatly improves the utilization rate of renewable resources, but also reduces resource waste; while ensuring that the slope protection structure is stable and durable, the components also incorporate environmental protection concepts and effectively improve the ecological environment; 2. Through the clever mutual splicing of standard components and filling with high-performance ecological concrete, the connection strength between blocks can be significantly improved, making the entire slope protection structure more compact and stable; not only the bearing capacity of the slope protection is enhanced, but also its long-term working performance is guaranteed, providing reliable protection for the protection of the river channel; 3. The design of the prefabricated components is extremely flexible. By adjusting the splicing method of the components and their overall size, various complex and changeable slope protection requirements can be easily met. Whether it is a gentle river channel with a small angle or a steep river bank with a large slope, a suitable component combination method can be found. At the same time, without changing the size of the ecological hole, by adjusting the external dimensions of the masonry, its scope of application can be further broadened to meet the actual needs of different river slope protection projects. When the size is increased, the applicable slope becomes smaller, and when the size is reduced, the applicable slope becomes larger. 4. The concave gear design used at the bottom not only enhances the connection strength between the blocks, making the entire slope protection structure more stable and reliable, but also greatly improves the stability and durability of the slope protection by increasing the bite force between the blocks and the river soil slope protection.

[0032] The specific technical solutions of the present invention are further described in detail below in conjunction with specific examples.

[0033] As shown in the figure, the multi-slope ecological prefabricated slope protection block described in the present invention includes a standard component and a special component. The standard component is composed of an upper double gear 1 and a lower 8-shaped base 2; the special component is composed of an upper single gear 3 and a lower annular base 4.

[0034] Furthermore, the upper double gear 1, the lower 8-shaped base 2, the upper single gear 3 and the lower annular base 4 can all be processed and formed in batches in advance at the prefabrication site, reducing the difficulty of construction.

[0035] Furthermore, a concave ecological hole 101 is arranged at the upper center of the upper double gear 1, and a convex docking column 102 is arranged at the lower part. Ecological concrete can be filled in the ecological hole 101 to increase the connection strength between blocks and improve the overall stability, and then grass can be planted to integrate into the river environment.

[0036] Furthermore, the lower 8-shaped base 2 is composed of two regular hexagonal prisms of the same size as the upper main body, the upper part of which is provided with an opening 201, and the lower part is provided with a first leg 203, a second leg 204, a third leg 205, a fourth leg 206, a fifth leg 207, and a sixth leg 208, a total of six legs; the six legs are formed by hollowing out a concave gear pore 202 that matches the shape of the upper double gear 1; the standard assembly is fixed together by inserting the docking column 102 into the lower 8-shaped base 2 through the opening 201;

[0037] The special assembly is assembled in the same manner as the standard assembly, that is, the upper and lower components are split into a single form and then connected.

[0038] Furthermore, these legs not only support the upper and lower splicing of blocks to achieve flexible construction, but the legs at the bottom layer can also be embedded in the original soil of the river channel, thereby effectively enhancing the stability and protection capabilities of the slope protection structure.

[0039] Furthermore, by changing the outer dimensions of the components, standard components of different specifications can be produced, so that the slope of the block construction can be accurately adjusted to meet the needs of various river bank protection.

[0040] Furthermore, the standard components can be nested up and down to form a staggered ecological slope protection, or laid flat to form a multi-hole slope protection;

[0041] The edges are smoothed with special components;

[0042] Ecological concrete can be filled into the ecological hole 101 to strengthen the bite force between the components and beautify the slope protection environment; the first leg 203, the second leg 204, the third leg 205, the fourth leg 206, the fifth leg 207, and the sixth leg 208 of the lower base, a total of six legs, can bite the soil of the river slope, thereby increasing the overall strength of the slope protection.

[0043] Furthermore, there are three laying methods for the same type of blocks, and the most suitable slope protection can be flexibly built by changing the laying method.

[0044] Furthermore, during assembly and laying, the actual operation process of the present invention is as follows:

[0045] Masonry assembly: Splice the upper double gear 1 and the lower 8-shaped base 2 to form an integral standard component. The same is true for the assembly of special components. It is simple and easy to operate, which improves the efficiency of on-site construction and assembly.

[0046] Laying method: Method 1: transport the assembled standard components and special components to the construction site and lay them one by one. After laying, fill the original ecological holes 101 and the later assembled ecological holes 101 with ecological concrete grass to increase the connection strength and integrate into the slope protection environment;

[0047] Method 2: transport the assembled standard components and special components to the construction site, level the bottom of the river channel and lay the blocks, insert the base side legs (first legs 203) of the second layer of blocks into the ecological holes 101 in the first layer of blocks, stack them one by one, trim the special components, fill the bottom pores (concave gear pores 202) with soil after the construction is completed, and then fill the ecological holes 101 with ecological concrete for planting grass. This method is suitable for rural rivers with steep slopes;

[0048] Method three: transport the assembled standard components and special components to the construction site, level the bottom of the river channel and lay the blocks, insert the front support leg (second support leg 204) of the base of the second layer of blocks into the ecological hole 101 in the first layer of blocks, stack them up in sequence, trim the special components, fill the bottom gap (concave gear gap 202) with soil after construction is completed, and then fill the ecological hole 101 with ecological concrete for planting grass. This method is suitable for wide rivers with gentle slopes.
