Abstract

The invention provides an environmentally-friendly novel soil solidifier. The environmentally-friendly novel soil solidifier comprises the following components in parts by weight: 10 to 25 parts of alkyl metal compound, 5 to 10 parts of triisopropanolamine, 6 to 20 parts of polyacrylic ester, 12 to 25 parts of water-soluble cellulose, 5 to 10 parts of phosphate, 3 to 8 parts of ferrous sulfate andthe balance of solvent. Metal ions in the alkyl metal compound in the soil solidifier usually are bivalent metal and can solidify soil, and the triisopropanolamine is provided, so that the solidification time is shortened and the soil solidification effects of high compressive resistance and high water tolerance are achieved; meanwhile, in the soil solidifier, the water-soluble cellulose and themetal ions in the alkyl metal compound are crosslinked into gel, so that the components are mixed uniformly and the engineering property is stable; furthermore, the ferrous sulfate cooperates with thephosphate, and adsorption and precipitation of heavy metal are induced, so that the biological toxicity and the transfer ability of the soil can be reduced, and the environmentally-friendly novel soil solidifier is economic and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of soil curing agents, in particular to an environmentally friendly novel soil curing agent. Background technique [0002] The soil stabilizer is composed of a variety of inorganic and organic materials. After being mixed with the soil at room temperature, it will cement the soil particles and fill the soil gaps through a series of physical and chemical reactions, turning the loose soil into a dense cementing material, thereby It is an environmentally friendly new engineering material that greatly improves the engineering properties such as the strength and durability of the soil. [0003] The research on soil stabilizer, represented by the United States, Japan and other countries, started earlier. The original single use of cement, lime, and fly ash has been developed to the mixing of various materials, forming a way to improve and enhance soil engineering performance. Composite material - soil stabilizer....
