Description

Technical Field

[0001] The utility model belongs to the technical field of ecological bricks, and in particular relates to a vegetative bare soil covered ecological brick. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Soil erosion caused by exposed soil or exposed solid waste from construction is a global problem, especially in arid, semi-arid and mountainous areas. At the same time, exposed soil and construction waste are easily washed away by rainfall, leading to soil erosion. This not only weakens the fertility of the land, but may also cause geological disasters such as mudslides and landslides. It is also easy to generate dust, which seriously affects air quality. These dusts may carry harmful substances and pose a threat to human health, especially increasing the risk of respiratory diseases. Exposed land and garbage accumulation areas may destroy local biological habitats and affect ecological diversity. At the same time, these areas are usually unable to grow plants, resulting in vegetation destruction and further deterioration of soil and water conservation functions. It will reduce land productivity, reduce biodiversity, and may lead to desertification. Soil and water conservation is essential for the sustainable development of agriculture and forestry, which can not only increase crop yields and forest coverage, but also protect natural resources.

[0004] In order to achieve mine reclamation and ecological restoration, restore the damaged ecosystem, and rebuild a stable soil structure and vegetation coverage, this can be achieved by laying ecological bricks. There are many ecological brick structures in the prior art. For example, Chinese utility model patent CN205444103U discloses an ecological slope protection brick, in which a core is filled in a hexagonal frame, a through hole is set at the center of the core, and soil is filled in the through hole and seeds are buried. This ecological brick structure provides a small growth space for plants. Due to the limitation of plant volume, the vegetation coverage rate is low; at the same time, due to the limitation of the seed growth environment, the entire growth process of vegetation is relatively slow, and environmental recovery requires a long time to achieve. Utility Model Content

[0005] The purpose of the utility model is to provide a vegetation-type bare soil covering ecological brick, which adds seed capsules and a raw permeable concrete matrix on the basis of traditional ecological bricks, effectively accelerating the growth rate of vegetation. At the same time, due to its more stable structure, it reduces the risk of soil erosion and contributes to soil and water conservation and ecological restoration.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] In the first aspect, an embodiment of the utility model provides a vegetation-type bare soil covered ecological brick, comprising a nutrient soil matrix, a vegetation permeable concrete matrix and a seed capsule, wherein the vegetation permeable concrete matrix is ​​located below the nutrient soil matrix, and the seed capsule is pre-buried in the nutrient soil matrix; a seed bin and a nutrient solution bin are provided in the seed capsule, and the seed bin and the nutrient solution bin are separated by a water-soluble degradable cementitious material.

[0011] As a further technical solution, the seed capsules are evenly distributed in the nutrient soil matrix, and the intervals between the seed capsules are not less than 3 cm.

[0012] As a further technical solution, the thickness of the nutrient soil matrix is ​​13-17 cm, and the thickness of the vegetation permeable concrete matrix is ​​8-12 cm.

[0013] As a further technical solution, the seeds in the seed capsule are wrapped with a heated sodium alginate solution.

[0014] As a further technical solution, the nutrient soil matrix with the seed capsules embedded in it and the vegetation permeable concrete matrix are formed at one time in a static pressure forming mold.

[0015] As a further technical solution, the pressure of the static pressure forming mold is set to 20-25Mpa.

[0016] As a further technical solution, the seeds in the seed capsule are plants that are resistant to drought and poor soil.

[0043] B. Mix sodium alginate and water in proportion, heat until dissolved and form a jelly.

[0044] C. Use a syringe or dropper to drop the hot sodium alginate solution into the double-layer mold with seeds and stir gently to ensure that each seed is evenly coated.

[0045] D. Liquid fertilizer is injected into the outer layer (gap part) of the double-layer capsule mold.

[0046] E. Pour the capsule solution into the outer part of the mold and seal the nutrient solution compartment. Make sure the capsule solution completely covers the nutrient solution to form a complete double-layer structure.
