Description

Technical Field

[0001] This utility model relates to the field of non-fired ecological slope protection brick technology, specifically a non-fired ecological slope protection brick based on phosphogypsum, construction waste and carbide slag. Background Technology

[0002] There are many methods for slope protection, but all are closely related to civil engineering technology. Using masonry, dry-laid stone, cast-in-place concrete slabs, and precast bricks for slope protection is the most common method due to its simple construction process, excellent protective effect, and significant impact. However, slopes treated using traditional civil engineering measures not only have poor landscape effects but also hinder vegetation growth, failing to purify the air and absorb noise, thus failing to achieve the desired environmental management results. Therefore, ecological slope protection bricks have emerged.

[0003] Ecological slope protection bricks are a special type of product used in slope management projects. They not only ensure the stability of slopes and soil and water conservation, but also focus on the protection and restoration of the ecological environment. They are now widely used in slope protection for hillsides, road edges, and river channels.

[0004] However, existing ecological slope protection bricks have the following problems:

[0005] 1. Not all slopes are suitable for plant growth, therefore slope environmental management cannot be achieved;

[0006] 2. Most plant seeds are grown using hydroseeding, a complex process;

[0007] 3. It uses a large amount of natural mineral resources, resulting in high costs and heavy weight;

[0008] 4. Lack of connecting structures results in poor overall stability;

[0009] 5. The drainage or grass planting structure design is complex and lacks practicality.

[0010] The Chinese patent, titled "An Ecological Slope Protection Structure for Water Conservancy Projects" (publication number CN221702289), discloses a slope protection brick containing slots, inserts, fixed rings, and sleeves. This design not only provides some protection for vegetation but also effectively prevents excessive water accumulation in planting troughs, thus avoiding root rot. However, this design is overly complex and intricate, hindering both production and on-site construction, resulting in poor practicality.

[0011] The Chinese patent, titled "Slope Protection Bricks and Interlocking Slope Protection Block Components" and with publication number CN220953219U, discloses a slope protection brick with a mating structure on its outer wall. This type of brick can form an interlocking structure with adjacent slope protection bricks, achieving the effect of soil stabilization and planting. The characteristic of this type of brick is that it has a hollow structure, and plant seeds are sown in the soil inside the brick. However, not all slopes have soil suitable for plant growth, which limits its application. Furthermore, the sowing method of this type of brick is relatively cumbersome and costly.

[0012] Based on the shortcomings of existing technologies, an ecological slope protection brick is proposed, which uses bulk solid waste as raw material, has a simple and easy production process, is lightweight and high-strength, and has a stable connection structure. It can achieve the effect of environmental governance while preventing landslides. Utility Model Content

[0013] The purpose of this utility model is to provide a non-fired ecological slope protection brick based on phosphogypsum, construction waste and carbide slag, in order to solve the problems mentioned in the background art that the existing ecological bricks on the market are not suitable for all slopes for plant growth, thus failing to achieve slope environmental management; plant seeds are mostly planted by hydroseeding, which is a complicated process; a large amount of natural mineral resources are used, resulting in high cost and weight; there is a lack of connecting structure, poor overall stability; and the drainage or grass planting structure design is complicated and lacks practicality.

[0014] To achieve the above objectives, this utility model provides the following technical solution: a non-fired ecological slope protection brick based on phosphogypsum, construction waste, and carbide slag, characterized in that it includes a square frame, a grass-planting filler, and a connecting body; the square frame and the grass-planting filler constitute a complete brick; the complete brick has pits around its perimeter, and the bricks are directly connected to each other through the connecting body to form a stable mortise and tenon structure; furthermore, the edges and bottom of the square frame are made from phosphogypsum, construction waste, and carbide slag as raw materials, which are mixed with water, pressed into shape, demolded, and cured to obtain the square frame.

[0015] Furthermore, the phosphogypsum and carbide slag are acidic and alkaline, respectively, and have a certain neutralizing effect after being mixed.

[0016] Furthermore, the grass filling material comprises a mixture of soil, phosphogypsum, carbide slag, seeds, and polymers; the phosphogypsum provides phosphorus-containing nutrients for plant growth, and the carbide slag is used to adjust the pH value of the filling material.

[0017] Preferably, the square frame has at least one recess on each side; the recesses are arranged both axially symmetrically and centrally symmetrically on the whole brick block.

[0018] Preferably, the connector has an axially symmetrical and centrally symmetrical structure, and the size of the recess matches the size of both ends of the connector to form a mortise and tenon structure.

[0019] Furthermore, the lengths of the connecting bodies are all the same, and the lengths are greater than the sum of the distances between the pits between the two bricks, so that the space formed when they are connected can serve as a drainage channel.

[0020] Preferably, there is at least one drainage hole on each side of the recess, and the drainage hole is positioned slightly higher than the bottom of the square frame; the drainage hole can connect the inside of the square frame with the drainage channel to prevent water accumulation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This non-fired eco-friendly slope protection brick, based on phosphogypsum, construction waste, and carbide slag, uses bulk solid waste as raw materials, has a simple and easy production process, is lightweight and high-strength, and possesses a stable bonding structure. Using phosphogypsum, construction waste, and carbide slag as raw materials not only reduces the consumption of natural mineral resources but also provides an effective way to process solid waste in large quantities. Compared to purchasing natural mineral resources, phosphogypsum, construction waste, and carbide slag are inexpensive, significantly reducing enterprise production costs. Due to the lightweight nature of phosphogypsum, the formed bricks are also lightweight, enhancing their practicality. Furthermore, addressing the cumbersome planting process of traditional eco-friendly slope protection bricks, a planting filler is inserted inside the brick. When soaked in water, the embedded seeds can grow into plants, reducing manual planting costs. Attached Figure Description

After demolding, it is as follows: Figure 1 As shown, a hollow brick with overall dimensions of 400 mm * 200 mm * 100 mm is obtained.

[0032] Specifically, the grass filling material is a mixture of soil, phosphogypsum, carbide slag, seeds, and polymers.

When the grass filling material comes into contact with water, the seeds can grow into plants.

[0033] Specifically, each side of the square frame 1 has at least one recess 3; the recesses 3 are arranged both axially symmetrically and centrally symmetrically on the whole brick block.

[0034] It should be noted that the bottom of the recess 3 should not penetrate the entire square brick; space must be left.

The length of the connector 4 needs to be greater than the distance between the recesses of the two bricks, and the space formed during connection can serve as a drainage channel 5.

[0036] Specifically, each recess has at least one drainage hole 6 on each side, and the drainage hole 6 is positioned slightly higher than the bottom of the square frame 1. In this embodiment, the center of the drainage hole 6 is 3 cm away from the bottom of the square frame 1.
