Soil stabilizer, stabilized soil and method for roadbed backfilling in soft stratum
The invention relates to the field of road engineering, and particularly discloses a soil stabilizer, stabilized soil and a method for roadbed backfilling in a soft stratum. The soft stratum roadbed soil stabilizer is prepared from the following raw materials in parts by weight: 10 to 30 parts of quick lime, 5 to 20 parts of aluminum oxide, 2 to 15 parts of silicon dioxide, 3 to 10 parts of triethanolamine, 2 to 10 parts of diisopropanolamine, 3 to 15 parts of a silane coupling agent, 5 to 20 parts of water glass and 2 to 15 parts of gypsum. The solidified soil comprises the following raw materials: soil, the soil stabilizer, cement and water. The method for roadbed backfilling in a soft stratum by using the solidified soil comprises the following steps of: uniformly mixing and stirring the solidified soil, backfilling and rolling layer by layer, and maintaining. According to the soft stratum roadbed soil stabilizer, all the components interact and cooperate with one another, the surface activity of soil particles can be improved, the bonding capacity of the surfaces of the soil particles is improved, and therefore the soil strength is improved.
本申请涉及道路工程领域，具体公开了一种土壤固化剂、固化土及在软弱地层进行路基回填的方法。软弱地层路基土壤固化剂包括以下重量份数的原料：生石灰10‑30份、氧化铝5‑20份、二氧化硅2‑15份、三乙醇胺3‑10份、二异丙醇胺2‑10份、硅烷偶联剂3‑15份、水玻璃5‑20份、石膏2‑15份；固化土包括以下原料：土、土壤固化剂、水泥、水；利用固化土在软弱地层路基的回填方法为，将固化土混合搅拌均匀后，分层回填碾压并进行养护。本申请的软弱地层路基土壤固化剂各个成份相互作用，相互配合，能够改善土壤颗粒表面活性、提高土壤颗粒表面的粘结能力，从而提升土壤强度。
