Problems solved by technology

In the 1970s, in developed countries such as Germany and the United States, the soil improvement technology was first developed in depth. The technical level has improved rapidly, and the modified materials have gradually changed from commonly used inorganic building materials such as cement and lime to organic materials. material direction, and has become a new type of soil stabilizer material specially used to strengthen the soil; currently, these new soil stabilizers and corresponding reinforcement technologies have mostly been used in traffic road engineering and water conservancy channel anti-seepage engineering, but they have a great impact on The solidification ability of the soil is generally weak, and the strength is low, and the impermeability is poor, which cannot meet the engineering requirements
[0003] In the field of water and soil management, there are relatively few anti-corrosion and growth-promoting curing agents, and the existing curing agents also have problems such as short service life, brittleness, cracking, and environmental pollution.

Embodiment 1

[0032] Weigh 4g of ordinary Portland cement, 0.35g of fly ash, 0.5g of silicon powder, 5g of dihydrate gypsum, 0.15g of naphthalene-based superplasticizer, and 190g of water to form a slurry with a solid content of 5%; weigh 0.6 g sodium polyacrylate is configured as a 0.6% aqueous solution.

[0033] Effect test:

[0034] Sprinkle 100 Bison Grass seeds in two groups of gravel soil respectively, and after shallow burial, the experimental group sprays the curing agent of the present invention according to the method of the present invention, repeating 3 times; the control group sprays the same amount of water. After 3 days, the compressive strength was tested.

[0035] The results showed that the strength of the experimental group was 3.3MPa, and that of the control group was 0 (the 7-day consolidation layer was broken by the vegetation and could not be tested). The germination rate of the experimental group was 92.7%. The germination rate of the control group was 41.5%. Aft...

Abstract

The invention discloses a consolidation growth-promoting stabilizer, and a preparation method and an application method thereof. The stabilizer is composed of the following components, by weight: 20-50% of common Portland cement, 1-30% of fly ash, 5-10% of silica fume, 30-50% of dihydrate gypsum, 0.5-1.5% of a dispersant, and 5-15% of sodium polyacrylate. The above components are prepared into liquid by using water with the method disclosed by the invention. When in use, with the method disclosed by the invention, soil is consolidated with a slurry injection manner using a high pressure gun. The stabilizer provided by the invention has high stabilization capacity and high adhesion to soil. With the stabilizer, soil capacities of absorbing and storing water can be improved. While an easily-weathered slope is effectively stabilized, sowed seed normal germination and growth can be ensured and can be promoted to a certain extent. Therefore, erosion can be resisted, vegetation restoration can be promoted, and good soil stabilization and regeneration effects can be realized. When the stabilizer is used in treatments of desertified areas and slopes, even more outstanding effect can be performed.

Description

technical field [0001] The invention relates to a soil curing agent for soil erosion slope control, in particular to a soil curing agent suitable for slopes below 45°, which has good soil curing effect and water retention function, and can resist erosion and promote vegetation restoration. The invention relates to a consolidation growth-promoting curing agent and a method for preparing and using the same, which belong to the field of environmental science. technical background [0002] Soil stabilizer has always been a hot issue in the field of soil and water conservation and slope management, which can significantly improve the physical and mechanical properties of the soil surface. Since the 20th century, many places have adopted a soil consolidation plan to solidify the soil when constructing roads, ports and other places, and the soil has been improved, and a series of good results have been achieved. In the 1970s, in developed countries such as Germany and the United S...
