A mobile sand-fixing unit and sand-fixing method

Abstract

The invention relates to a movable sand-fixing unit and a sand-fixing method, comprising a bottom support with a plurality of meshes, a sealing baffle is fixed on the edge of the bottom support, the bottom support and the sealing baffle form a box structure, and the bottom support The upper surface is laid with an air-permeable water-proof layer, a planting layer, an air-permeable water-permeable layer and a grid layer arranged sequentially from bottom to top inside the box structure. The planting layer is used for planting plants, and the air-permeable water-permeable layer is provided for plant Through the through holes, the planted plants can pass through the air-permeable and water-permeable layer and the mesh layer through the through holes and the mesh of the mesh layer. The construction of the sand-fixing unit of the present invention is quick and convenient, and solves the problem of sand utilization, accumulation and sand-fixation. problem of contradictions.

Description

technical field [0001] The invention relates to the technical field of sand-fixing devices, in particular to a movable sand-fixing unit and a sand-fixing method. Background technique [0002] Today's world is facing serious ecological problems such as serious destruction of forest vegetation, soil desertification and desertification, which pose a serious threat to the sustainable development of society. With the gradual increase of the Yellow River Diversion Project, including the use of the Yellow River Water Project and the Yellow River Diversion Project, a large amount of sediment will inevitably be introduced, and the traditional sedimentation method of dredging instead of sinking is basically adopted in the grit chamber, and the dredged mud The sand is deposited on the shore, forming a large area of ​​sandy wasteland, and the accumulation of sand is exposed, forming a local barren land. The sediment in the Yellow River is mainly fine sand, which is very easy to produce...

AI Technical Summary

Problems solved by technology

For this kind of bare barren sandy land, it is difficult to form an ecology by natural forces to prevent wind erosion. In addition, due to the continuous generation of silt and sand, and sometimes the use of silt, the sandy wasteland will continue to increase, expand or shrink, and will continue to change. It has caused great difficulties to the problem of sand fixation

A large number of exposed soil slopes will be formed on railway slopes, highway slopes, river embankments, lake embankments, and areas with severe desertification. For these exposed soil slopes, if the ecological balance is restored purely by natural forces, that is, the germination and growth of plants It is very slow, and even if it is restored, it will be very messy. In addition, some soil slopes cannot be completely restored, which will cause great damage to the ecological green environment.

[0003] The traditional method of biological sand fixation is to prevent and control deserts, stabilize oases, and improve the environmental quality of sandy areas by planting plants and other means. The inventors found that the sand control effect is slow and some areas with harsh natural conditions are difficult to provide plants for survival. basic conditions, and the inventor also found that after the above three sand-fixing methods are used, the sediment cannot be utilized, and there is a contradiction between the utilization, accumulation and sand-fixation of the sediment, and the construction cost is relatively high
