Description

Technical Field

[0001] This utility model relates to the field of concrete block technology, specifically to a phosphogypsum-based vegetation-type ecological concrete block. Background Technology

[0002] Existing ecological blocks are mostly made of ordinary cement, which has problems such as high alkalinity, which is not conducive to plant growth, high cost, and lack of ecological value. Directly using phosphogypsum on slopes poses risks of low strength, poor water resistance, and potential leaching of harmful components. There is an urgent need for an innovative block structure that can simultaneously meet the multiple goals of ecological vegetation, soil stabilization and slope protection, and solid waste utilization. Utility Model Content

[0003] The purpose of this invention is to provide a phosphogypsum-based plant-based ecological concrete block to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A phosphogypsum-based vegetation-type ecological concrete block includes: A phosphogypsum block, wherein the phosphogypsum block has planting holes; The phosphogypsum block is provided with arc-shaped interlocking blocks and square interlocking blocks, which are located on adjacent sides of the phosphogypsum block. The phosphogypsum blocks are provided with arc-shaped interlocking grooves and square interlocking grooves. The arc-shaped interlocking blocks cooperate with the arc-shaped interlocking grooves to make two phosphogypsum blocks interlock from front to back. The square interlocking blocks cooperate with the square interlocking grooves to make two phosphogypsum blocks interlock from side to side.

[0005] Preferably, the arc-shaped interlocking block is provided with an arc-shaped slot, and the phosphogypsum block is also provided with a semi-circular sliding block.

[0006] Preferably, the arc-shaped slot is inserted into the semi-circular sliding block, allowing the phosphogypsum blocks to be stacked vertically.

[0007] Preferably, the phosphogypsum block is provided with a drainage channel, one end of which is opened in the planting hole and the other end is opened between the arc-shaped interlocking blocks.

[0008] Preferably, the planting hole is filled with planting filler material.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The phosphogypsum block material in this invention is environmentally safe after curing, and the planting filler in the planting holes provides an excellent growth substrate for plants with suitable alkalinity and a high success rate of greening. The connection structure between the blocks provides excellent erosion and sliding resistance. The plant roots and blocks form a composite slope protection system that combines flexibility and rigidity, which is far superior to a single material. Both phosphogypsum blocks and vegetation fillers consume large amounts of phosphogypsum, achieving a perfect combination of engineering application and ecological restoration, turning waste into treasure; Phosphogypsum blocks are prefabricated in the factory and assembled on site, which is fast, requires no large equipment, and is easy to maintain.

[0012] 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.

[0013] Please see Figures 1 to 3 This utility model provides a technical solution: A phosphogypsum-based vegetation-type ecological concrete block includes: The phosphogypsum block 1 has planting holes 2 on it. The phosphogypsum block 1 is made of high-strength phosphogypsum-based material. The material composition is: phosphogypsum, slag powder and cement as the main cementing materials. Through alkaline activation and polymer emulsion (such as VAE emulsion) modification, the block is ensured to have sufficient strength (compressive strength ≥15MPa) and water resistance, and to effectively solidify heavy metals.

[0014] The planting hole 2 is filled with planting filler 10, which is a mixture of improved phosphogypsum nutrient soil (phosphogypsum, garden soil, organic fertilizer, water-retaining agent, and slow-release fertilizer in a certain proportion), plant fiber, and grass seeds. This mixture is weakly acidic or neutral, rich in nutrients and water required for plant growth, providing space and nutrients for seed germination and root growth. After the roots grow, they can penetrate the planting hole 2 and anchor into the slope, forming a strong reinforced soil stabilization network.

[0015] The phosphogypsum block 1 is provided with an arc-shaped interlocking block 3 and a square interlocking block 4. The arc-shaped interlocking block 3 and the square interlocking block 4 are located on adjacent sides of the phosphogypsum block 1.
