AI Technical Summary

Technical Problem

In the prior art, when dealing with solid waste inorganic materials, it is difficult to effectively improve the strength and water stability of the soil, especially in the absence of aggregates, the traditional method is costly and has poor structural stability.

Method used

Solid waste inorganic material modifiers, including water, tert-butyl acrylamide sulfonic acid, calcium lignin sulfonate, sodium tripolyphosphate, sodium hydroxide, polyacrylamide, ethylenediamine and sodium gluconate, are used to form a mixed liquid by adding these ingredients to the water in a specific proportion, and mixing them thoroughly with soil and ordinary silicate 42.5 cement, and then press them in the mold and undergo constant temperature and humidity maintenance.

Benefits of technology

It significantly improves the water repellency of the soil and the water stability of the structure, so that it can meet the strength requirements of foundation treatment, and can replace traditional cement-stabilized gravel structures, and can be adjusted to flowing mud state for backfill to ensure the controllability of backfill quality.

Abstract

The invention discloses a solid waste inorganic material modifier and a use method thereof. The solid waste inorganic material modifier comprises water, tert-butyl acrylamide sulfonic acid, calcium lignosulphonate, sodium tripolyphosphate, sodium hydroxide, polyacrylamide, ethylenediamine and sodium gluconate. Adding the materials into water in proportion to form a mixed solution; fully stirring and mixing the mixed solution, a soil body and ordinary silicate 42.5 cement to obtain a mixture; the mixture is placed in a mold to be pressed and fixed, and constant-temperature and constant-humidity curing is carried out for more than 7 days; the hydrophobic property of a soil body and various powdery solid wastes can be improved, under the aggregate-free condition, an inorganic gelling material is supplemented, so that the structure meets the strength requirement and the water stability requirement, can be used for foundation treatment, can also replace a traditional cement stabilized macadam structure and can be adjusted to be in a flowing slurry state for foundation pit fertile groove backfilling, and the construction efficiency is improved. And the controllability of backfilling quality is ensured. The soil body or solid waste powdery particles treated by the soil stabilizer can greatly improve the hydrophobicity and improve the water stability of the structure.
