Preparation method of sand reinforcing agent and rapid curing method of medium-coarse sand
The invention discloses a preparation method of a sandy soil reinforcing agent and a rapid curing method of medium-coarse sand, and belongs to the technical field of engineering construction.The rapid curing method of the medium-coarse sand comprises the steps that firstly, the medium-coarse sand is naturally paved; 2, a sandy soil reinforcing agent is applied to the naturally-paved medium-coarse sand; and thirdly, the first step and the second step are repeated in sequence till the medium-coarse sand is stacked and a conical stacking body is formed. Medium-coarse sand is laid in a layered mode, the sandy soil reinforcing agent is sprayed to each layer of medium-coarse sand, sodium alginate and sodium carboxymethyl starch in the sandy soil reinforcing agent and medium-coarse sand particles form gelling matter through the gelling effect, and therefore the cohesive force and strength between the particles are increased, a stacked body is reinforced and becomes more stable and firmer, and the stacking effect is improved. In addition, the subsequent use performance is not affected, the preparation process of the sand reinforcing agent is simple, and medium-coarse sand piles can keep good engineering stability in large-scale engineering application.
本发明公开了一种砂土加固剂的制备方法及中粗砂的快速固化方法，属于工程建设技术领域，本中粗砂的快速固化方法包括步骤一：将中粗砂进行自然摊铺；步骤二：向自然摊铺的中粗砂施加砂土加固剂；步骤三：依次重复步骤一和步骤二，直至中粗砂堆存完毕并形成锥形堆放体。分层铺设中粗砂，并对每层中粗砂喷淋砂土加固剂，砂土加固剂中的海藻酸钠和羧甲基淀粉酸钠通过胶凝作用与中粗砂颗粒形成胶凝物，从而增加颗粒之间的粘聚力和强度，使堆放体得到加固，变得更加稳定和坚固，并且不影响后续的使用性能，且砂土加固剂的制备工艺简单，能够在大规模工程应用中使中粗砂堆保持良好的工程稳定性。
