Embodiment 1

[0028] Embodiment 1 A kind of fiber soil mixed spraying method

[0029] The spraying method: mix the spraying substrate with water, stir it evenly with a spraying machine to make a slurry, and then spray it on the slope surface.

[0030] The spraying substrate includes heat-treated wood fiber and soil; 5000 grams of heat-treated wood fiber is added per cubic soil (ie 1.4 tons).

[0031] The heat-treated wood fibers: porous fibers with a length of 1.5-2.5 cm and a diameter of 0.05-0.15 mm; fibers with a length of 2 cm have a content of ≥50%.

[0032] The preparation method of the heat-treated wood fiber: it is formed by pyrolyzing bark and wood chips under high temperature and high pressure conditions; high temperature and high pressure conditions: the high temperature and high pressure conditions: the pressure is 345 kPa, and the temperature is 193°C.

Embodiment 3

[0038] Embodiment 3 A kind of fiber soil mixed spraying method

[0039] The spraying method: mix the spraying substrate with water, stir it evenly with a spraying machine to make a slurry, and then spray it on the slope surface.

[0040] The spraying substrate includes heat-treated wood fibers and soil; 3000 grams of heat-treated wood fibers are added per cubic soil (ie 1.4 tons).

[0041] The heat-treated wood fibers: porous fibers with a length of 1.5-2.5 cm and a diameter of 0.05-0.15 mm; fibers with a length of 2 cm have a content of ≥50%.

[0042] The preparation method of the heat-treated wood fiber: it is formed by pyrolyzing bark, wood chips, etc. under high temperature and high pressure conditions; high temperature and high pressure conditions: the pressure is 340 kPa, and the temperature is 195°C.

[0043] After testing, using the spraying method of Example 1-3, the mud with a water content of 65% mixed with fiber soil was sprayed on the slope with a slope ratio of 1:...

Abstract

The invention provides a fiber soil mixed spray-seeding method. According to the fiber soil mixed spray-seeding method, an adopted spray-seeding matrix comprises heat-treated wood fibers. The heat-treated wood fibers are 1.5-2.5 cm in length and 0.05-0.15 mm in diameter. According to the heat-treated wood fibers, the content of the fibers with the lengths of 2 cm is larger than or equal to 50%. Onthe basis of not using the means such as cement, concrete and wire meshes which destroy the soil structure, the adhesive force of a matrix layer on a slope is strong, and the thickness of the matrixsprayed by one time is increased by 2 to 3 times compared with that of traditional spray-seeding.

Description

technical field [0001] The invention relates to a spraying method, in particular to a fiber soil mixed spraying method, which belongs to the technical field of environmental protection. Background technique [0002] In the slope restoration project, in order to allow plants to grow on the slope, it is necessary to cover the slope with a substrate layer for plant growth. The substrate layer can be mellow soil, or a mixed substrate mixed with binders, fertilizers, etc. Plants obtain nutrients, water, etc. from the substrate layer to supply growth. Achieve greening effect in a short period of time. [0003] In the slope repair method, the matrix layer of the repaired slope needs to be attached to the slope, but the matrix layer itself has poor adhesion ability and is easy to be washed and slipped; especially in heavy rain weather, it is difficult to resist rain erosion. In the prior art, in order to increase the adhesion of the matrix layer, technicians often increase the ad...
