Improved loess and preparation method, construction method and application thereof
The invention relates to improved loess and a preparation method, a construction method and application thereof. The improved loess is prepared from the following components in percentage by mass: 4-8% of acetylene sludge, 4-8% of sodium silicate and 84-92% of loess of required improved soil bodies, and the improved loess is formed by uniformly mixing the acetylene sludge, the sodium silicate andthe loess. According to the improved loess and the preparation method, the construction method and application thereof, the acetylene sludge and the sodium silicate are used for mixing and improving aloess foundation, the improved foundation is large in strength, small in transformation and high in water stability, meanwhile, the brittleness is low, coefficients of collapsibility are obviously reduced, meanwhile, the utilization efficiency of the acetylene sludge is improved, and the problems of occupied land sources and environmental pollution due to massive stacking of the acetylene sludgeare solved. Used improved materials are low in price, low in implement cost, simple and feasible in construction technology, and have good economic benefits.
本发明涉及一种改良黄土及其制备方法、施工方法和应用，改良黄土包括质量百分比为4～8％的电石渣，质量百分比为4～8％的水玻璃，质量百分比为84～92％的所需改良土体的黄土，改良黄土由电石渣、水玻璃和黄土均匀混合而成。本发明提出利用电石渣和水玻璃混合改良黄土地基，改良后的地基不仅强度大、变形小、水稳定性高，同时脆性较低，湿陷性系数显著减小，同时提高了电石渣的利用效率，改善了因电石渣大量堆放占用土地资源和污染环境的问题，本发明利用的改良材料价格低廉，实施成本低，施工工艺简单可行，具有较好的经济效益。
