Preparation method of curing agent for curing soft soil to broaden roadbed
The invention provides a preparation method of a curing agent for curing soft soil to broaden a roadbed, and the curing agent is prepared from the following raw materials in percentage by mass: 32-50%of high-calcium fly ash, 5-25% of bentonite, 5-15% of cement, 10-15% of heavy calcium carbonate, 1-10% of hydrophilic fiber and 0-3% of an early strength agent. The preparation method comprises the following steps: adding the high-calcium fly ash, the cement, the heavy calcium carbonate and the hydrophilic fiber into a stirring device, uniformly stirring, adding the bentonite and the early strength agent, and continuously stirring uniformly to obtain the curing agent provided by the invention. Different curing agent proportions are selected according to different natural water contents of soft soil, so that the bearing capacity of a soft soil foundation is obviously improved, the settlement amount of the foundation is reduced, and the roadbed stability is improved; the preparation processis simple, the raw materials are easy to obtain, the cost is low, the treated soft soil is high in strength, industrial waste is reasonably utilized, and the application value is high.
本发明提供一种固化软土拓宽路基的固化剂的制备方法，该固化剂由包括如下质量分数的原料制成：高钙粉煤灰32%～50%、膨润土5%～25%、水泥5%～15%、重质碳酸钙10%～15%、亲水性纤维1%～10%、早强剂0～3%，先将所述高钙粉煤灰、水泥、重质碳酸钙以及亲水性纤维加入搅拌设备中拌和均匀，然后再加入所述膨润土和早强剂继续搅拌均匀，即可得到本发明所述的固化剂。本发明根据软土的天然含水量不同，选择不同的固化剂配比，明显提高软土地基承载力、减少地基的沉降量及提高路基稳定性；本发明的制备工艺简单，原材料易获取，成本较低，处理后的软土强度高，且合理利用了工业废料，具有较高的应用价值。
