Problems solved by technology

Therefore, cement has been widely used in construction of roads, ports, airports and other projects. Due to lime soil, cement soil has good frost resistance and various advantages of itself, and has been widely used in major projects, but in During the construction, it was gradually discovered that lime soil and cement soil have low strength, large drying shrinkage, and easy cracking, and their performance is greatly affected by soil quality. The curing effect on plastic clay, organic soil, and saline soil is relatively poor, and sometimes even no curing effect

Abstract

The invention discloses a high-molecular organic soil solidifying agent and a synthetic method of same. The solidifying agent includes 2-6 parts of magnesium chloride, 4-8 parts of calcium chloride, 0.3-0.8 parts of calcium oxide, 0.3-0.8 parts of magnesium oxide, 3-8 parts of acrylamide, 0.1-0.4 parts of ammonium persulfate, 0.2-0.6 parts of potassium persulfate, 10-20 parts of soluble cellulose, 5-15 parts of sodium carboxymethylcellulose, 0.5-1 part of sodium hydroxide and 50-70 parts of water. The high-molecular organic soil solidifying agent is simple in operation, is low in cost, is quick in effect and is green and environment-friendly, is excellent in solidifying effect on soil, is strong in anti-pressure ability, achieves standard requirement, and is suitable for construction of various roads, fields and the like.

Description

technical field [0001] The invention relates to soil solidification technology, in particular to the soil solidification technology applicable to various roads and foundation constructions. Background technique [0002] In order to meet the needs of life, people have long applied plant fibers and ginger stones to improve various properties of soil engineering. After lime was invented, lime became the most commonly used material for improving soil. With the development of society, after cement was invented, cement has gained people's attention for its good mechanical properties and stability. Therefore, cement has been widely used in construction of roads, ports, airports and other projects. Due to lime soil, cement soil has good frost resistance and various advantages of itself, and has been widely used in major projects, but in During the construction, it was gradually discovered that lime soil and cement soil have low strength, large drying shrinkage, and easy cracking, ...
