Method for reinforcing calcareous sand foundation
The invention discloses a method for reinforcing a calcareous sand foundation, which comprises the following steps of: uniformly pouring aspergillus sydowii liquid from the surface of the calcareous sand foundation, pouring auxiliary liquid after pouring the aspergillus sydowii liquid for 1-1.5 hours each time, and pouring reaction liquid after 1-1.5 hours to react for 8-10 hours; repeating the steps; the auxiliary liquid is an aqueous solution containing 0.1 to 0.3 g/L of phenylalanine; the reaction liquid is a mixed aqueous solution of urea and calcium chloride. The problems that in the calcareous sand foundation reinforcing process, the reinforcing strength is not ideal, and the reinforcing uniformity is poor are effectively solved. After reinforcement treatment is conducted through the method, the surface strength range of the foundation reaches about 22-25 MPa, the reinforcement strength and uniformity are good, and the reinforcement effect is good.
本发明公开了一种钙质砂地基的加固方法，包括以下步骤：从钙质砂地基表面均匀倾倒聚多曲霉菌液，每次倾倒菌液1～1.5小时后，倾倒辅助液，再1～1.5小时后倾倒反应液反应8～10小时；重复以上步骤；所述辅助液为：含0.1～0.3g/L苯丙氨酸的水溶液；所述反应液为：尿素和氯化钙的混合水溶液。本发明有效解决钙质砂地基加固过程中的加固强度不理想和加固均匀度较差的问题。经本发明方法加固处理后，地基表面强度范围达到22～25MPa左右，加固强度和均匀度较好，加固效果良好。
