The invention discloses a ceramic tile as well as a preparation method and application thereof. The ceramic tile comprises the following components in percentage by mass: 62-78% of ore weathered powder and 22-38% of bauxite. The mineral weathered powder and the bauxite are compounded to prepare the ceramic tile, recycling of the mineral weathered powder is achieved, the problem of stockpiling of the mineral weathered powder and the problem of shortage of raw materials in the brick making industry are solved, and the prepared ceramic tile meets the performance requirement of the optimal-grade first-class ceramic tile (the water absorption rate is lower than 3%) in the national standard (GB / T 4100-2015).

The application discloses a low-carbon solidified soil matrix and application. The matrix is made of dredged soil, biochar, slag and gypsum mixed in a specific ratio, and the preferred ratio (T1) is that the mass ratio of the dredged soil, the biochar, the slag and the gypsum is 60:15:10:15. By comparing the mechanical properties and the plant growth effects of different ratios (CK, T1, T2 and T3), it is found that the unconfined compressive strength of the T3 ratio (with the highest content of slag) is the highest (up to more than 3000kPa) after 60 days; however, the T1 ratio (with the highest content of biochar) exhibits the best ecological effect, including significantly promoting the growth of ryegrass, increasing the biomass, optimizing the carbon-nitrogen ratio of soil and enhancing the soil microbial activity, while maintaining sufficient engineering strength (about 1000kPa after 60 days) and excellent dry-wet cycle performance. The application realizes the balance between the mechanical and ecological restoration functions through the collaborative utilization of multi-source solid wastes, and provides an economic, environment-friendly and efficient solution for erosion areas.

The invention belongs to the technical field of ecological slope protection, and particularly relates to a soil fixation flood control ecological regulation and storage slope protection. Comprising a plurality of slope protection brick units which are inserted up and down and clamped left and right; each slope protection brick unit comprises a slope protection brick and a water absorption and guide block, and the slope protection brick is higher than the water absorption and guide block; conical piles are inserted into the slope protection bricks, and the lower ends of the conical piles are inserted into the slope. The slope protection brick is good in anti-sliding capacity, a self-locking structure is formed between the slope protection brick units, stability is kept in the transverse direction and the longitudinal direction, and a slope body is more stable; in addition, the protection slope can bear broken stones, mud scraps or rainfall runoff which roll down from the slope top, the broken stones, mud scraps or rainfall runoff are accumulated in the protection slope brick units, and the landslide risk is reduced. The protection slope has better landscape and ecological effects, water can be stored step by step, the stored water and nutrients carried by the charcoal matrix are utilized, and growth and maintenance of vegetation and an ecological system in a region are supported.

The invention provides an ecological restoration device for an ocean light beach and a using method of the ecological restoration device, and belongs to the technical field of ocean engineering and water environment engineering. The ecological restoration device for the ocean light beach comprises a planting cylinder, planting soil, a cushion material, a clamping groove, a landing pile and a buoyancy block. The ecological restoration device for the ocean light beach is ecological, is made of moso bamboo, and is ecological and environment-friendly; pollution and energy consumption are avoided; components are standard and easy to produce; according to the ecological restoration device for the ocean light beach, it is guaranteed that the ecological restoration device horizontally falls to the beach face, planting soil can be prevented from losing, and therefore the purpose of planting sea grass on the light beach is achieved.

Hollow hump type ecological slope protection structure: composed of a hump part and a plane part, the hump part includes a hump solid part and a hump hollow part, the plane part includes a plane solid part and a plane hollow part; the hump part is a strip boss composed of the solid parts on both sides of the hump and the plane solid parts on the top, rectangular holes are opened in the solid parts on both sides of the hump, and the hump hollow part is used for wave dissipation and water permeability; the plane part is the plane solid part at the bottom between the two humps, and rectangular holes are opened in the plane solid part, and the plane hollow part is used for wave dissipation and water permeability. The present invention has good energy dissipation effect, can effectively absorb wave energy, reduce water climbing, reduce wave height, help reduce the impact of waves on the structural stability of hydraulic structures, and control land water and overtopping. The present invention itself has good stability. Due to its high water permeability, the negative pressure is small when the wave trough acts, and the wave force it is subjected to is also relatively small.
