Curing agent for stabilizing soil

Abstract

The invention relates to an environment-friendly curing agent for stabilizing soil, which can improve the bearing capacity of a subgrade. The curing agent for stabilizing the soil is characterized by comprising the following components in parts by weight: 2-18 parts of polyanionic cellulose, 2-6 parts of sodium sulfate or calcium sulphate, 12-50 parts of sulfonic acid, 2-53 parts of granulated blast furnace slag, 1-5 parts of neutral water glass and 38-150 parts of water. The curing agent for stabilizing the soil can remarkably improve the bearing capability of the cured soil and has good antiseepage effect and durability, and the situation of argillization can be reduced after the curing agent is soaked in the water; therefore, the environment-friendly curing agent is suitable for various construction pavements, in particular rural roads developed for travel and agriculture with the requirements of low cost, short construction period and fast effect. The environment-friendly curing agent not only improves the road construction quality, but also makes the material application and the construction process more environment-friendly, can be further applied to the base course and surface course of road and construction engineering and the fields of wind prevention and sand consolidation, canal seepage control, burning-free low-carbon environment-friendly bricks and the like, and is suitable for the semimechanical operation and the large-scale mechanical construction operation in country.

Description

1. Technical field [0001] The invention relates to an environment-friendly stable soil solidifying agent capable of improving roadbed bearing capacity, in particular to a stable soil solidifying agent of polyester polymer compound. 2. Background technology [0002] In road engineering and municipal infrastructure construction, the soil stabilizers and curing agents used are generally strongly alkaline. The most traditional method is to add a certain proportion of quicklime to the soil, and then roll it after mixing with the soil. Due to various Influenced by factors, such as the erosion of rainwater, this strong alkaline soil stabilizer will salinize the surrounding soil, pollute surface water and groundwater, and seriously affect the ecological environment. Therefore, this method not only causes serious pollution to the environment during construction, but also is difficult to obtain high-quality roadbed. [0003] Although other substances have appeared in the market to re...

Problems solved by technology

For example, the stabilizer mentioned in the Chinese Patent Soil Stabilizer (ZL02114518.0), after applying the stabilizer, still has the subgrade soil loose after rainwater soaking, and the road surface is caused to have potholes after being rolled by a car. The function is single, and it cannot solve the problems of low impermeability and strength, poor soil fixing effect and durability, and is not suitable for use in areas with a lot of rain
