Soil curing agent for water conservancy dam and preparation method of soil curing agent

Abstract

The invention discloses a soil solidifying agent for water conservancy dams and a preparation method thereof. The raw materials of the soil solidifying agent for water conservancy dams include Portland cement clinker, water, industrial waste residue, aliphatic sulfonate, and sulfamic acid Acid, water-soluble silicone, lime, anhydrite, triethanolamine, polycarboxylic acid compound, sorbitol monolaurate, first elicitor, second elicitor; raw materials for first elicitor sodium sulfate, sodium nitrite, Calcium chloride, calcium nitrite, ammonium persulfate and ethylenediamine; the raw materials of the second elicitor include sodium polyacrylate, water-based epoxy resin, titanate coupling agent, ethanol and ethylene glycol monobutyl ether. The soil curing agent of the present invention has high compressive strength, less construction consumption, low transportation costs, and little impact on project cost, and embankment crests, dams, and roads built with it have compressive resistance, durability, waterproof and high adaptability; It can replace or partially replace natural materials for roofing and slope protection to meet the urgent needs of sustainable development of water conservancy and transportation.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a soil solidifying agent for water conservancy dams and a preparation method thereof. Background technique [0002] Water conservancy projects are a major project involving people's livelihood and a strong support for my country's economic and social development. The quality of water conservancy projects is related to the life, property and safety of the country and people. The construction quality of embankment crests, dams, and slope protection in water conservancy projects is also an important link in flood control and disaster reduction. Therefore, the technical requirements for seepage prevention, waterproofing, and freeze-thaw resistance in the construction of embankment crests, dams, and slope protection are very important. [0003] In the construction of embankment crests, dams, and slope protection of water conservancy projects, the project requires...

AI Technical Summary

Problems solved by technology

[0003] In the construction of embankment crests, dams, and slope protection of water conservancy projects, the project requires a large amount of curing agents. The commonly used curing agents are mostly lime, cement, etc. The disadvantage of this type of traditional curing agent is that the early strength of the cured soil is not high. Adding a large amount, the solidified soil is easy to dry and shrink, forming cracks, destroying the structure, affecting water stability, and it is difficult to obtain high-quality roadbed

Moreover, the dust in the production, processing, transportation, storage and use of these traditional construction materials is serious, polluting the surrounding environment, and the calcination of limestone will release a large amount of CO2 gas, which will aggravate the greenhouse effect

Moreover, it is difficult to obtain high-quality roadbed using this type of traditional curing agent.

Although ion solutions and bio-enzyme curing agents have appeared in modern times, these curing agents have strong selectivity to soil components, which limits the popularization and application of products.

[0004] In the face of the increasing shortage of natural curing agent resources, it is impossible to meet the resource supply of water conservancy and transportation construction, which restricts the construction of water conservancy and transportation, and the use of traditional curing agents will pollute the ecological environment. How to solve the shortage of curing agent supply, Reducing the negative impact of water conservancy and transportation construction on the ecological environment has become an urgent research issue
