Premixed weathered sandstone flow state solidified soil for loess filling area cracks
The invention relates to premixed weathered sandstone flow state solidified soil for cracks in a loess filling area. The flow state solidified soil is prepared from the following raw materials in parts by weight: 90 to 110 parts of weathered sandstone coarse aggregate, 40 to 55 parts of loess, 20 to 30 parts of quick lime, 10 to 20 parts of weathered sandstone fine aggregate, 6 to 8 parts of expansive soil, 10 to 15 parts of cement, 1 to 2 parts of short aramid fiber and 0.5 to 1 part of pumping agent. Compared with a traditional single filling material, the premixed weathered sandstone flow state solidified soil has the characteristics of high strength, weak shrinkage performance, low consolidation settlement and low permeability, and can solve the problems of irregular development and difficult filling in cracks of a loess filling site; the method is suitable for filling and reinforcing work after a large number of cracks appear in a fill site due to large span of geological units, complex geological conditions, different fill thicknesses and human or natural factors when strategic engineering of building a city by flat mountains and filling ditches and reclaiming lands is implemented in western loess areas.
本发明涉及一种用于黄土填方区裂缝的预拌风化砂岩流态固化土，该流态固化土由下述重量份的原料组成：风化砂岩粗骨料90~110份、黄土40~55份、生石灰20~30份、风化砂岩细骨料10~20份、膨胀土6~8份、水泥10~15份、短芳纶纤维1~2份以及泵送剂0.5~1份。本发明所得预拌风化砂岩流态固化土相比于传统单一的填充材料，具有强度高、收缩性能弱、固结沉降低、渗透性能低的特点，可以解决黄土填方场地裂缝内部发育不规则、填充难的问题，适用于西部黄土地区实施平山造城、填沟造地战略工程时，由于地质单元跨度大、地质条件复杂、填方薄厚不同以及人为或自然因素影响导致填方场地内出现大量裂缝后的填充加固工作。
