AI Technical Summary

Technical Problem

Red mudstone is prone to softening and disintegration when exposed to water, leading to engineering problems such as landslides, slope rock mass cracking and deformation, and roadbed loosening. Existing technologies are unable to effectively suppress this water-sensitive problem.

Method used

Water-sensitive inhibitors were prepared by vacuum ball milling using raw materials such as carbon fiber, nano-tin antimony oxide, potassium methylsilicate, and γ-propyltrimethoxysilane. These inhibitors were then sprayed onto the surface of red mudstone to form a hydrophobic film and a skeleton-filling structure, thereby improving the hydrophobicity and strength of the material.

Benefits of technology

It effectively inhibits the water absorption, softening, and disintegration of red mudstone, improves the material's resistance to disintegration and strength, reduces porosity, prevents engineering defects, and is environmentally friendly and cost-effective.

Abstract

本发明公开了一种能抑制水敏性红层泥岩遇水崩解的方法:在红层泥岩表面喷洒疏水改性溶液,包括碳纤维:0.05‑0.3%、纳米氧化锡锑:0.2%‑0.5%、甲基硅酸钾:2%‑5%、γ‑丙基三甲氧基硅烷:2%‑5%、其余为水。本发明方法能较好抑制毛细水渗入红层泥岩内部,从而预防红层泥岩发生吸水软化崩解,且操作简单、环境友好、成本低廉。可应用于高陡边坡、路基边坡及路基填料中,提升红层泥岩耐崩解性,防止水敏性崩解工程病害的发生。
