Embodiment 1

[0020] According to the percentage by weight, 60% industrial waste silica powder, 20% pregelatinized starch, and 20% sodium polyacrylate (molecular weight above 1,000,000) were mixed and ground for 1 hour to obtain the soil stabilizer of the present invention. 0.5% of the total weight of the soil curing agent is stirred and mixed with grass seeds, soil and water to form a sludge, which is sprayed on the slope. Rinse with a small amount of water after 10 minutes without collapse or loss. The grass seeds germinated and thrived after 3 days.

Embodiment 2

[0022] According to the percentage by weight, 60% of fly ash, 20% of pregelatinized starch and 20% of sodium polyacrylate (molecular weight above 1,000,000) are mixed and ground for 1 hour to obtain the soil stabilizer of the present invention. 0.5% of the total weight of the soil curing agent is stirred and mixed with grass seeds, soil and water to form a sludge, which is sprayed on the slope. Rinse with a small amount of water after 10 minutes without collapse or loss. The grass seeds germinated and thrived after 3 days.

Embodiment 3

[0024] According to weight percentage, 60% of blast furnace slag, 20% of pregelatinized starch and 20% of sodium polyacrylate (molecular weight above 1,000,000) are mixed and ground for 1 hour to obtain the soil stabilizer of the present invention. 0.5% of the total weight of the soil curing agent is stirred and mixed with grass seeds, soil and water to form a sludge, which is sprayed on the slope. Rinse with a small amount of water after 10 minutes without collapse or loss. The grass seeds germinated and thrived after 3 days.

Abstract

The invention discloses a green and environment-friendly soil stabilizer taking industrial waste as raw material and an application method thereof, which overcomes the problem of the prior art that lime or cement is taken as the main component of hardening agent, and the lime or cement is hardened to form a fully dense structure, plants can not grow in the structure, so the road greening can not be realized, and other problems. The soil stabilizer of the invention takes the industrial waste as raw material, the industrial waste is evenly mixed with pre-gelatinized starch and sodium polyacrylate, the industrial waste can be of one or the combination of more kinds of coal ash, blast furnace slag or silica micropowder and is used for solidifying soil and preventing water loss and soil erosion; the application method is as follows: the soil stabilizer, plant seed, soil and water are stirred into complex soil, and then the complex soil is coated on the construction surface, the complex soil can be solidified in short time, and usually can not generate water loss and soil erosion under the rainfall condition. The soil stabilizer of the invention has good water permeability, air permeability, water-retaining capacity and nutrient preserving capability, has neutral PH value and facilitates the sprouting and growing of plants.

Description

technical field [0001] The invention relates to a soil curing agent used for road construction, water and soil loss prevention and vegetation greening. Background technique [0002] Existing soil solidification materials mainly adopt hardening agents mainly composed of lime or cement. These cured materials form a completely dense structure after hardening, in which plants cannot grow, which is not conducive to greening in road construction. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned technologies, and to provide a green environmental protection soil curing agent preparation method that makes full use of industrial waste to protect the environment, realize sustainable development and reduce costs. [0004] The green and environment-friendly soil solidifying agent of the present invention takes industrial waste as the main raw material, and is uniformly mixed with pregelatinized starch and sod...
