Description

Technical Field

[0001] This utility model relates to the field of concrete blocks, and in particular to a reinforced self-embedding porous concrete block. Background Technology

[0002] With the acceleration of urbanization, the problem of urban surface hardening has become increasingly prominent. Traditional impermeable paving materials prevent rainwater from infiltrating, which can easily lead to problems such as waterlogging, insufficient groundwater replenishment, and exacerbation of the heat island effect. Porous concrete block paving is of great significance for preventing soil erosion of surface water bodies, maintaining the safety and stability of river and lake banks, and improving biodiversity.

[0003] The existing masonry blocks are fixed by mortar or adhesive materials, which requires many construction steps, increases the construction period, and the stability after paving is not good. After long-term use, adjacent concrete blocks are prone to loosening and displacement, requiring additional connectors or mortar to ensure the connection between adjacent blocks, which increases construction costs and difficulty. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a reinforced self-embedding porous concrete block, which aims to improve the problem in the prior art that "there are many construction steps, and additional connectors or mortar are needed to ensure the connection between adjacent blocks is stable".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced self-embedding porous concrete block, comprising a concrete block, wherein the concrete block is composed of block one, block two, block three, and block four. Block one has reserved spaces on its front and left sides for forming holes when it cooperates with another block. Block one also has grooves on its front and left sides. Block two has reserved spaces on its rear and right sides for forming holes when it cooperates with another block. Block two has an integrally formed insert fixedly connected to its left side and a groove on its rear side. Block three has reserved spaces on its rear and left sides for forming holes when it cooperates with another block. Block three has an integrally formed insert fixedly connected to its front side and a groove on its right side. Block four has reserved spaces on its rear and right sides for forming holes when it cooperates with another block. Block four has an integrally formed insert fixedly connected to its front and left sides.

[0006] As a further description of the above technical solution: The cross-section of the insert is a right trapezoid with rounded corners at the edges, and two inserts are combined to form a prism with an isosceles trapezoidal cross-section.

[0007] As a further description of the above technical solution: Ecological holes are provided in the middle of each of the blocks 1, 2, 3 and 4. The ecological holes are prism structures with triangular cross sections.

[0008] As a further description of the above technical solution: The hole is a cylindrical structure with a circular cross-section.

[0009] As a further description of the above technical solution: Both the holes and the ecological holes penetrate vertically through the upper and lower surfaces of the concrete block.

[0010] As a further description of the above technical solution: The sum of the areas of the holes and ecological holes formed after the concrete blocks are laid accounts for 35% of the total paved area.

[0011] As a further description of the above technical solution: The edges of the multiple concrete blocks after paving are connected by edge strip one and edge strip two.

[0012] This utility model has the following beneficial effects: 1. In this utility model, two corresponding inserts are fitted together in the groove and interlock with each other, restricting the relative displacement of the blocks in any two-dimensional direction, such as front and back or left and right, in the horizontal direction.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a reinforced self-embedded porous concrete block, comprising a concrete block 1, which is prefabricated from porous concrete instead of traditional ordinary concrete. The material is ordinary silicate cement with a grade of 42.5, crushed stone, water-cement mixture, mineral admixtures, high-performance water-reducing agents, alkaline slow-release agents, etc., mixed and formed by stirring, pressing, vibrating or tamping. The porous structure can provide a surface for microorganisms to attach and grow, in which microorganisms can carry out metabolic and other life activities, participate in the degradation and transformation of pollutants in water, and help improve water quality. The four corners of the outer wall of the concrete block 1 are rounded to facilitate demolding. The concrete block 1 is composed of block one 11, block two 12, block three 13 and block four 14.

[0018] Reference Figure 1 - Figure 3 Block 11 has reserved spaces on its front and left sides that will form holes 15 when it mates with another block. Block 11 also has grooves 112 on its front and left sides. Block 212 has reserved spaces on its rear and right sides that will form holes 15 when it mates with another block. A single-piece insert 111 is fixedly connected to the left side of Block 212, and a groove 112 is provided on its rear side. Block 313 has reserved spaces on its rear and left sides that will form holes 15 when it mates with another block. The front side of the block is fixedly connected with an integrally formed insert 111, and the right side is provided with a groove 112. The rear and right sides of the block 14 are provided with reserved spaces that can be used to form holes 15 when they cooperate with another block. The front and left sides of the block 14 are fixedly connected with integrally formed inserts 111. During the paving operation, each concrete block 1 is connected to each other through the cooperation of the insert 111 and the groove 112. The two inserts 111 are combined and fitted into the groove 112, which restricts the horizontal displacement of adjacent blocks and forms a stable paving surface.

[0019] Reference Figure 2 and Figure 3 The cross-section of the insert 111 is a right trapezoid with rounded corners at the edges. Two inserts 111 are combined to form a column with an isosceles trapezoidal cross-section. During paving, the two corresponding inserts 111 are interlocked in the groove 112 to restrict the displacement of two adjacent blocks in any direction in the horizontal position. No block will have relative displacement in the two-dimensional direction, thus ensuring the safety and stability of the paved surface. No connectors or fasteners are required. After the blocks are connected into a piece, a stable paved surface is formed. It has the advantages of flexible combination application, simple and convenient construction, and saving construction costs.

[0020] Reference Figure 1 - Figure 3 Ecological holes 16 are provided in the middle of blocks 11, 12, 13, and 14. The ecological holes 16 are prism structures with triangular cross sections, providing space for the growth of aquatic plants. For example, some aquatic plants can take root and grow in the holes, thus providing habitats, breeding grounds, and shelters for aquatic insects, fish, shrimp, and other small animals. This is conducive to building a diverse aquatic ecosystem. Holes 15 are cylindrical structures with circular cross sections. The porous structure gives the precast blocks good permeability. When water flows through holes 15, it will rub against the walls of holes 15. At the same time, the direction and velocity of the water flow will change continuously, consuming the energy of the water flow, reducing the scouring of the revetment foundation, improving the revetment's scouring resistance, and extending the service life of the revetment. Holes 15 and ecological holes 16 penetrate the upper and lower surfaces of concrete blocks 1 vertically. The sum of the areas of holes 15 and ecological holes 16 formed after the concrete blocks 1 are laid accounts for 35% of the total paved area.

[0021] Reference Figure 4 Multiple concrete blocks 1 are connected by edge strip 1 21 and edge strip 22 after paving. Edge strip 1 21 and edge strip 22 are used to seal the edges after paving to ensure the stability and aesthetics of the overall structure.

[0022] Working principle: During use, the precast concrete blocks 1 are transported to the construction site and dry-laid on a flat and compacted base according to the design layout. During construction, blocks 11, 22, 33, and 44 are spliced ​​together in sequence through their unique interlocking structure. When adjacent blocks are joined, the insert 111 on one block is inserted into the corresponding groove 112 of the other block. The two right-angled trapezoidal blocks 111 are embedded into the groove 112 after being spliced ​​together, forming a column structure with an isosceles trapezoidal cross section. Due to the self-locking property of the trapezoidal structure, when subjected to external loads or water flow impact, normal pressure is generated between the insert 111 and the groove 112, which further enhances the interlocking force and effectively restricts the relative displacement of the blocks in any two-dimensional direction in the horizontal direction, such as front-back and left-right. This achieves self-locking between the blocks, forming a stable and non-loose paving structure without the need for mortar, connectors, or fixing bolts.

[0023] After the paving is completed, the reserved spaces between adjacent blocks are aligned to form circular holes 15 that penetrate the upper and lower surfaces. These holes, together with the ecological holes 16 in the middle of each block, form a multi-channel, multi-scale interconnected pore system. This system ensures good structural strength and excellent permeability. Rainwater or surface runoff can quickly infiltrate vertically into the base soil through the holes 15 and ecological holes 16, effectively reducing the hydrostatic pressure behind the revetment and preventing structural instability caused by water pressure accumulation. At the same time, the rough concrete surface inside the pores provides abundant attachment sites for microorganisms. Through the metabolism of microorganisms, organic pollutants and other substances in the water are degraded, thus exerting a natural purification function and improving the nearshore water quality.

[0024] Furthermore, in ecological applications, planting soil can be filled into holes 15 and ecological holes 16, and suitable aquatic or wetland plants, such as reeds, cattails, and rushes, can be planted. The plant roots penetrate deep into the pores and the base layer, further anchoring the blocks and soil, enhancing the overall stability of the slope. After the vegetation grows, it forms a green shoreline, which not only beautifies the environment but also provides habitat, breeding, and refuge space for insects, frogs, small fish, and other organisms, promoting the connectivity of aquatic and terrestrial ecosystems and the restoration of biodiversity. Under the scouring action of water flow, the porous structure can disperse the direction of water flow, increase the flow channel resistance, consume the kinetic energy of water flow, significantly reduce the direct scouring of the revetment foundation by water flow, improve the scouring resistance, and extend the service life of the project.

[0025] For the edge of the paved area, special edge strips 21 and 22 are used for edge sealing. The inner side of the edge strip is provided with a groove structure that matches the block insert 111, which can firmly fasten the edge block, prevent the edge from loosening or collapsing, and ensure the safety and appearance integrity of the overall structure.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
