Grouting material for reinforcing silty cohesive soil karst cave as well as preparation method and application of grouting material
The invention discloses a grouting material for reinforcing a silty cohesive soil karst cave as well as a preparation method and application thereof. The grouting material for reinforcing the silty cohesive soil karst cave is prepared from the following components: cement, coal ash, mineral powder, a water reducing agent, rubber powder, silicon-based nano hybrid emulsion, calcium carbonate, quartzsand, shale ceramsite, cellulose ether and water. The grouting material for reinforcing the silty cohesive soil karst cave has the following effects: (1) water is drained, and the soft plastic stateof a covering layer is improved into capable of being molded into a hard plastic state so as to improve the erosion resistance; (2) the stress condition of the top plate of the karst cave is improved;(3) the anti-seepage capability is improved, and the change speed of underground water level and the influence degree on the covering layer are reduced; and (4) the permeability of macroporous stratum is reduced by filling the grouting material, the permeability is greatly improved, the permeability of the stratum is obviously reduced, and the key reinforcement of the stratum within a depth rangeis realized.
本发明公开了用于粉质粘性土溶洞加固的注浆材料、制备方法及其应用。所述用于粉质粘性土溶洞加固的注浆材料，包括如下组分：水泥，粉煤灰，矿粉，减水剂，橡胶粉，硅基纳米杂化乳液，碳酸钙，石英砂，页岩陶粒，纤维素醚，水。本发明所述用于粉质粘性土溶洞加固的注浆材料承载能力增强，具有以下效果：①排出水分，将覆盖层软塑状态提高为可塑至硬塑状态，提高抗冲刷侵蚀能力；②改善溶洞顶板受力状况；③提高防渗水能力，减小地下水位变化速度和对覆盖层的影响程度；④通过灌入注浆材料降低了大孔隙地层的渗透率，渗透性得到大幅度改善，地层的渗透性显著下降，实现了深度范围内地层的重点加固。
