Collapsible loess composite grouting material as well as preparation method and application thereof
The invention discloses a collapsible loess composite grouting material, which comprises a liquid A and a liquid B. The liquid A and the liquid B are independently stored and mixed in use. The liquidA comprises following components in parts by weight: 60-100 parts of water, 100 parts of cement and 5-15 parts of an accelerator. The liquid B comprises the following components in parts by weight: 100 parts of water and 100 parts of water glass. The grouting material has the advantages that the solidification speed is quick, the solidification time is easy to control, the permeability is good, and the impermeability is good. The grouting material is suitable for solidification of tunnel full-section water-rich collapsible loess, collapsible loess foundation treatment of newly-built buildingsor equipment foundations and collapsible loess foundation treatment of buildings or equipment foundations with differential settlement. The invention also discloses a preparation method of the collapsible loess composite grouting material. The preparation method comprises the following steps: fully stirring 60-100 parts of water and 100 parts of cement to form cement slurry, adding 5-15 parts of an accelerator into the cement slurry to form a liquid A; and uniformly stirring 100 parts of water and 100 parts of water glass to form a liquid B. When the collapsible loess composite grouting material is used, the liquid A and the liquid B are mixed to obtain the collapsible loess composite grouting material.
本发明公开了一种湿陷性黄土复合型注浆材料，包括单独保存且在使用时混合的A液和B液，其中，按混合时的重量份计，A液包括水60‑100份、水泥100份、速凝剂5‑15份；B液包括水100份、水玻璃100份，具有凝固速度快、凝固时间容易控制、渗透性好、抗渗性佳的优势，适用于隧道全断面富水湿陷性黄土的固化、新建建筑或设备基础湿陷性黄土地基处理、存在不均匀沉降的建筑或设备基础湿陷性黄土地基处理；本发明还公开了上述湿陷性黄土复合型注浆材料的配制方法：将60‑100份水和100份水泥充分搅拌，形成水泥单液浆，将5‑15份速凝剂掺入水泥单液浆形成A液；将100份水和100份水玻璃搅拌均匀形成B液；需要使用湿陷性黄土复合型注浆材料时，将A液和B液混合即得。
