Embodiment 1

[0038] It is used for the slope protection project of highway soil slope with height H>3m. A reinforced wheat straw fiber blanket with a width of 2500mm and a thickness of 12mm was selected as the base blanket, and an ordinary wheat straw fiber blanket with a width of 2500mm and a thickness of 8mm was selected as the main material for construction. The construction process is as follows:

[0039] 1. Slope treatment

[0040] Clean up the miscellaneous rocks and debris on the slope, and backfill the low-lying areas to make sure the slope is smooth.

[0041] 2. Laying fiber blanket

[0042] (1) Laying: Lay the plant fiber blanket on the slope from top to bottom along the slope, and keep a smooth combination between the fiber blanket and the slope.

[0043] (2) Pre-embedded: The plant fiber blanket extends 40-80cm at the top of the slope, buried in the soil and compacted (it can be combined with the construction of the drainage ditch).

[0044] (3) Anchoring: Fix the plant fib...

Embodiment 2

[0052] It is used for slope protection engineering of river embankment soil slope with height H>3m. A reinforced hemp palm fiber blanket with a width of 2500mm and a thickness of 12mm was selected as the base blanket, and an ordinary wheat straw fiber blanket with a width of 2500mm and a thickness of 8mm was selected as the main material for construction. The construction process is as follows:

[0053] 1. Slope treatment

[0054] Clean up the miscellaneous rocks and debris on the slope, and backfill the low-lying areas to make sure the slope is smooth.

[0055] 2. Laying fiber blanket

[0056] (1) Laying: Lay the plant fiber blanket on the slope from top to bottom along the slope, and keep a smooth combination between the fiber blanket and the slope.

[0057] ⑵Pre-embedded: The plant fiber blanket extends 40-80cm at the top of the slope, buried in the soil and compacted.

[0058] (3) Anchoring: Fix the plant fiber blanket with U-shaped steel bars with a length of 20cm, a ...

Abstract

The invention belongs to the field of ecological engineering and relates to a construction method of spraying and covering planting in an ecological restoration project, namely, a vegetation restoration method adopting a plant fiber blanket with the assist of slurry spraying. The invention is characterized in that the method comprises the following steps: laying a slope through the plant fiber blanket firstly, spraying and covering the slope through slurry and covering the slope through the plant fiber blanket. In the invention, a three-dimensional net made of geotextile material can be replaced; chemical synthetic materials entering the natural world can be obviously reduced when the effect of improving the overall and local stability of the slope is achieved; moreover, vegetable fiber can also increase organic components of soil, is beneficial for improving the capacities of water retaining and constant-temperature keeping of the soil on the surface layer and is beneficial for the growth of vegetation on the slope; when the construction cost is reduced, the low carbon conversion and utilization of agricultural and forestal residuals are realized, agricultural and forestal chains are extended, and the industrial added value of by-products is improved; and the method has a large application value in the soil and water conservation, sand prevention and control and ecological restoration of the damaged vegetation in a project in China.

Description

technical field [0001] The invention belongs to the field of ecological engineering and relates to a construction method for spraying and covering planting in ecological restoration engineering. Background technique [0002] For the high and steep soil slopes left over from engineering wounds, the slope protection technology of hanging three-dimensional mesh vegetation is usually used. In recent years, the slope protection technology of plant fiber blankets has appeared. The former uses industrially produced three-dimensional net-wrapped structure geonet, combined with soil covering and spray planting technology to combine engineering material soil stabilization technology and spray planting vegetation restoration technology to achieve the purpose of vegetation restoration and ecological slope protection. The latter adopts the industrial production of agricultural and forestry plant fibers to form blankets containing plant seeds, covering the slope to achieve the purpose of ...
