Embodiment 1

[0025] 1. Selection of soil materials and reagents

[0026] The soil samples were taken from the typical original soil slopes in Changsha area. The common soil samples were crushed and placed on porcelain plates and spread out evenly, and then placed in an oven to air dry. The ground soil samples were passed through a 20-mesh standard sieve, and finally the sieved soil materials were put into an airtight container and stored in a cool place.

[0027] The screening of reagents is based on the principles of water absorption, water retention, and coagulation, while fully considering the following points: 1) Good stability, stable performance, easy to disperse into a stable network system, and a long cycle; 2) Good cementation , strong permeability, equivalent viscosity; 3) less dosage, fast and durable, economical and reasonable; 4) no pollution or little pollution, easy to biodegrade; 5) scientific and reasonable formula, simple preparation process, convenient application. Fina...

Abstract

The invention discloses a soil solidifying agent with a compound function and a use method thereof. The soil solidifying agent is used for preventing soil, sand dunes and the like from being subjected to wind erosion, water erosion and generating environmental pollution. Anionic polyacrylamide, sodium silicate and aluminum sulfate are selected as the components of the soil solidifying agent. According to an L9 (34) orthogonal design, three levels of concentration is selected for each reagent. An unconfined compressive strength test, an indirect tensile strength test and a water soaking test are used for testing a formed standard test piece, thereby obtaining an optimal formula of the soil solidifying agent. A test result shows that a novel soil solidifying agent developed in a spraying applying form has an excellent solidifying function and obtains an excellent composite economic benefit. The soil solidifying agent is an ideal environment-friendly product and has a huge ecological environmental protection benefit.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to the fields of roads under construction in cities, mine pavement, tailing ponds, wasteland, sand dune stabilized soil, etc., and specifically relates to a soil-fixing agent with composite functions and its application method. Background technique [0002] In places such as bare soil and sand dunes, in dry and windy seasons, the dust on the surface is easily generated by the wind. It not only causes air, clean ground and water environment pollution, affects the growth of crops, but also threatens human health. Facing the increasingly serious problem of dust pollution, it is necessary to develop a soil-fixing agent and apply it to the surface of soil, sand dunes, etc. to form a relatively stable state, which will solve this problem. [0003] At present, in addition to the commonly used soil-fixing agents, such as lime, cement and various industrial waste residues, some scien...
