Method for reinforcing loess by inducing calcium carbonate deposition through combination of guar gum and soybean urease
A method for reinforcing loess by inducing calcium carbonate deposition through combination of guar gum and soybean urease is characterized in that guar gum and a curing solution are respectively added into loess soil according to a certain proportion, and the combined reinforcing effect of the guar gum and the curing solution is achieved; the guar gum is added to provide a plurality of nucleation sites for the curing solution in the soil body, so that the generation amount of the calcium carbonate is increased, and the calcium carbonate is uniformly distributed in the soil body; the bonding effect of the guar gum and calcium carbonate generated by the soybean urease solution play a dual reinforcing effect, on one hand, soil particles are stabilized, and on the other hand, soil pores are filled with the calcium carbonate, so that the overall strength of the solidified soil body is greatly improved; the water sensitivity and permeability of the solidified soil body are greatly reduced, the compressive strength, crack resistance and water stability of loess are effectively improved, and the method has the advantages of being environmentally friendly, good in adaptability and high in solidification efficiency.
一种瓜尔豆胶联合大豆脲酶诱导碳酸钙沉积加固黄土的方法，通过将瓜尔豆胶与固化溶液按一定比例分别添加到黄土土料中，实现了两者的联合加固效应；瓜尔豆胶的加入为固化溶液在土体中提供多个成核位点，从而增加了碳酸钙的生成量，且使得碳酸钙在土体中均匀分布；瓜尔豆胶的粘结作用与大豆脲酶液所生成的碳酸钙起到双重加固作用，一方面稳定了土颗粒，另一方面碳酸钙填充土壤孔隙，从而极大提升了固化土体的整体强度；本发明不仅大幅降低了固化土体的水敏性和渗透性，而且有效提升了黄土的抗压强度、抗裂性能和水稳定性，具有绿色环保，适应性好，固化效率高的特点。
