Embodiment Construction
[0010] Figures 1 and 2 together describe an embodiment of the present invention. In this example, on the vacuum membrane of the conventional vacuum preloading method, the water-covered and overloaded preloading is carried out inside; the settlement observation is carried out according to the vacuum preloading operation regulations for each settlement observation point, and when the preloading settlement reaches the calculated settlement value When it is above 80%, continue to preload for 5 to 10 days, and stop the water-covered overload vacuum preload after confirming that it is completely stable; remove the vacuum film and dry it for 1 to 2 days, and then perform power drainage and consolidation to quickly remove the overload vacuum preload For the water stored in the sand cushion layer, after the water level reaches below 1.5m, carry out dynamic compaction or vibratory rolling. In the vacuum membrane of the conventional vacuum preloading method, the water-covered overload pr...
