Description

Technical Field

[0001] The utility model relates to the field of ecological restoration, in particular to an assembled self-locking ecological concrete precast brick for slope vegetation restoration. Background Technique

[0002] With the continuous promotion of ecological civilization construction, green and low-carbon development has gradually become one of the development concepts of major enterprises. During the engineering construction process, reducing carbon emissions and improving resource utilization efficiency through means such as design optimization, improvement of construction technology methods, and material selection are important starting points for protecting the ecological environment and achieving sustainable development. For this reason, a variety of concrete precast blocks and self-locking precast blocks have been successively introduced in China. However, most concrete precast blocks only reserve holes with a certain size inside the bricks for plant growth, resulting in the vegetation coverage rate of the slopes where the concrete precast blocks are spliced and constructed far from meeting the engineering acceptance standards. At the same time, after the non-designed self-locking concrete precast blocks are spliced and constructed on-site, affected by natural and human factors, the settlement of the slope causes the splicing area of the concrete precast blocks to break away, resulting in local collapse, and the concrete precast blocks have poor effects on slope protection and vegetation restoration.

[0003] In recent years, ecological concrete technology has been gradually popularized and applied in the slope safety protection and vegetation restoration of production and construction project engineering, achieving relatively good ecological restoration effects. In most application cases, ecological concrete construction is carried out by means of on-site mixing, paving, curing, etc. of materials, involving a large number of personnel and different mechanical equipment entering the site, consuming a large amount of manpower, material resources, and financial resources. At the same time, some projects lack sites for material mixing and mechanical equipment placement and use, and the on-site coordination is difficult.

[0004] Therefore, in the context of ecological civilization construction and green and low-carbon development, based on the current application mode of ecological concrete technology, there is an urgent need for an ecological concrete brick precast technology that can not only meet the requirements of slope safety protection and vegetation restoration of projects, but also reduce carbon emissions, improve construction efficiency, and reduce the impact of the project on the external environment. Therefore, the utility model patent designs an assembled self-locking ecological concrete precast brick for slope vegetation restoration. This technology will effectively improve the slope safety protection standard of production and construction project engineering, increase the slope vegetation coverage rate, enhance the overall stability after the splicing of ecological concrete precast blocks, significantly reduce carbon emissions during project construction, and is of great significance for vigorously promoting the realization of the "dual carbon" goal of the whole process of green and low-carbon project construction. Content of the Utility Model

[0005] The object of the present utility model is to solve the problems in the application of existing concrete precast bricks in engineering slopes, such as complex splicing process, local collapse, vegetation coverage rate, and on-site paving construction of ecological concrete, and to provide an assembled self-locking ecological concrete precast brick on which plants can grow and the overall stability of the splicing blocks can be ensured.

[0006] To achieve the above object, an assembled self-locking ecological concrete precast brick for slope vegetation restoration designed by the present utility model includes a precast brick main body. The precast brick main body is in the shape of a hexagonal prism. Three of the six side faces of the hexagonal prism are provided with card slots at intervals, and the other three side faces are provided with insertion columns corresponding to the card slots. The card slots and the insertion columns are of square structure. A central hole is also provided in the middle part of the precast brick main body, and the central hole penetrates through the precast brick main body.

[0007] Further, the central hole is composed of multiple holes or a single hole, and the cross-section of the hole is circular, square or hexagonal.

[0008] Further, two card slots are respectively provided on three of the side faces of the precast brick main body at intervals, and two insertion columns are respectively provided on the other three side faces.

[0009] Further, the square dimensions of the card slots and the insertion columns are the same, and the space of the card slots is reserved for the insertion columns.

[0010] Further, the proportion of the area of the central hole in the cross-section of the ecological concrete precast brick is 1.54%-9%.

[0011] The advantages of the present utility model are as follows: The ecological concrete precast brick itself is an eco-friendly material. The brick is made by mixing and pressing materials such as water, cement, coarse aggregate, ecological agent, and alkali-reducing agent during the precast process, and has a large pore structure with a moderate pH value, meeting the external environmental requirements for the rooting and germination of herbaceous plants; the reserved central hole in the ecological concrete precast brick further increases the pores of the brick body itself, providing a growth space for herbaceous plants and shrubs; through the ingenious design of the card slots and insertion columns on the six side faces of the ecological concrete precast brick, multiple identical ecological concrete precast bricks can be tightly spliced and stacked through the card slots and insertion columns to achieve the overall assembly of the ecological concrete precast bricks on the slope; the ecological concrete precast brick is prefabricated and pressed in advance, and can be mass-produced. The sizes of the card slots and insertion columns on the six side faces of the ecological concrete precast brick are small, and the card slots and insertion columns are not easily damaged, which is convenient for transportation. The construction process is simple, meeting the requirements of low-carbon, environmental protection, and ecological restoration in engineering construction. Description of the Drawings

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Taking an assembled self-locking ecological concrete precast brick for slope vegetation restoration as a reference, the technical solution of the patent will be described in conjunction with the attached drawings:

[0026] Figure 1 It is the top view plan and isometric view of the assembled self-locking ecological concrete precast brick in the first embodiment, including a precast brick main body 1, a central hole 2, a card slot 3, and an insertion column 4. The precast brick main body 1 is in the shape of a hexagonal prism. Three of the six sides of the hexagonal prism are provided with card slots 3 at intervals, and the other three sides are provided with insertion columns 4 corresponding to the card slots 3. The card slots 3 and the insertion columns 4 are of square structure, and the square sizes of the card slots 3 and the insertion columns 4 are the same. The space of the card slot 3 is reserved for the insertion column 4. A central hole 2 is also left in the middle part of the precast brick main body 1, and the central hole 2 penetrates through the precast brick main body 1. The central hole 2 is composed of multiple holes or a single hole, and the cross-section of the hole is circular, square or hexagonal. In this embodiment, it is circular. In this embodiment, two card slots 3 are respectively provided on three of the six sides of the precast brick main body 1 at intervals, and two insertion columns 4 are respectively provided on the other three sides.

[0027] Among them, the precast brick main body 1 itself is a large-pore structure, and the brick body itself meets the germination environment of plant grass seeds through alkali reduction treatment, and the large-pore structure provides a guarantee for plant rooting.

[0028] Among them, the central hole 2 can further increase the plant growth space. After covering the soil in the central hole 2, it meets the growth environment of both herbaceous plants and shrubs. At the same time, through the distribution design of the central hole 2, the overall aesthetic degree of the slope is improved after the ecological concrete precast bricks are stacked.

[0029] Among them, the precast brick main body 1 realizes the self-locking function through the mutual tight connection of the card slot 3 and the insertion column 4 on the side of the brick body, so that there is no gap between the ecological concrete precast bricks. After the ecological concrete precast bricks are assembled and spliced, the overall stability of the slope is high.

[0030] Among them, the precast brick main body 1 is a block formed by pressing. When multiple identical blocks are stacked, no other accessories are required to form a self-locking assembled ecological concrete slope surface.

[0040] Figure 11 It is the overall sectional effect drawing of the slope after on-site stacking, soil covering, grass planting, and maintenance in Embodiment 1 of the present invention, including the precast brick main body 1, the slope 5, the central hole 6 after filling soil, the herbaceous plants 7, the plant roots 8, and the shrubs 9.

[0041] It should be noted that the central hole 2 in Example 1 is composed of thirteen small cylindrical holes, and these thirteen small cylindrical holes penetrate the precast brick main body 1. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 3.93%; the central hole 2 in Example 2 is a cylindrical hole, and this cylindrical hole penetrates the precast brick main body 1. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 2.72%; the central hole 2 in Example 3 is an equilateral hexagonal prism, and this equilateral hexagonal prism penetrates the precast brick main body 1. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 9%.

[0042] It should be noted that the central hole 2 in the fourth embodiment is composed of a large cylindrical hole and eight small cylindrical holes. The large cylindrical hole is located at the center of the ecological concrete precast brick, and the eight small cylindrical holes are evenly distributed around the large cylindrical hole. Both the large cylindrical hole and the small cylindrical holes penetrate through the main body 1 of the precast brick. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 5.14%. The central hole 2 in the fifth embodiment is composed of a large cubic hole and eight small cylindrical holes. The cross-section of the large cubic hole is square. The large cubic hole is located at the center of the ecological concrete precast brick, and the eight small cylindrical holes are evenly distributed around the large cubic hole. Both the large cubic hole and the small cylindrical holes penetrate through the main body 1 of the precast brick. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 3.96%. The central hole 2 in the sixth embodiment is a large cubic hole. The cross-section of the large cubic hole is square. The large cubic hole penetrates through the main body 1 of the precast brick. The area ratio of the central hole in the cross-section of the ecological concrete precast brick is 1.54%.

[0043] It should be known that the cross-section of the central hole 2 of the six ecological concrete precast bricks designed in the first to sixth embodiments accounts for 1.54% - 9% of the cross-section of the entire ecological concrete precast brick, and the proportion is relatively small, so that the compressive strength of the ecological concrete precast brick is less affected by the central hole. At the same time, the ecological concrete brick is made by mixing and pressing materials such as water, cement, coarse aggregate, ecological agent, and alkali reducing agent. The porosity of the non-opening area itself is very large. Reserving the central hole 2 in the central part thereof will further increase the porosity of the ecological concrete precast brick.

[0044] As mentioned above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
