Vacuum combined surcharge preloading foundation treatment method
The invention belongs to the technical field of vacuum combined preloading foundation treatment, and particularly relates to a vacuum combined surcharge preloading foundation treatment method. According to the method, soil bags in the reclamation land from the sea are combined with a fluid soil to form a fluid-state soil bag protection layer to replace a sand protection layer in vacuum combined preloading, the fluid-state solidified soil close to the liquid state cannot generate shearing force due to the fact that the fluid-state solidified soil is large in fluidity and close to liquid in property when being injected, a sealing film below the fluid-state solidified soil is not affected, therefore, the sealing film is not damaged in the construction process. After injection construction is finished, due to the fact that a curing agent is doped, the strength of the curing agent can be gradually improved, the curing agent becomes high-strength solidified soil, certain bearing capacity is achieved, a construction platform can be provided for an upper vehicle, and it is guaranteed that stacking and loading are conducted quickly and smoothly in the later period.
本发明属于真空联合堆载预压地基处理技术领域，具体涉及一种真空联合堆载预压地基处理方法。本发明将围海造地中的土工袋与流态土相结合，形成流态土工袋保护层以代替真空联合堆载预压中的砂保护层，接近液体状态的流态固化土由于注入当时流动性大，性质接近液体，不会产生剪力，对下面的密封膜没有影响，从而保证在施工过程中不破坏密封膜。注入施工结束后，由于掺入有固化剂，所以其强度会逐步提高变成强度较高的固化土，具有一定的承载力，可以为上部车辆提供施工平台，保证后期堆载的快捷顺利进行。
