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 2
[0033] Embodiment 2 A kind of fiber soil mixed spraying method
[0034] 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.
[0035] The spraying substrate includes heat-treated wood fiber and soil; add 4000 grams of heat-treated wood fiber per cubic soil (ie 1.4 tons).
[0036] 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%.
[0037] 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 350 kPa, and the temperature is 190°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:...
