Three-dimensional deep soft soil composite foundation and construction method
The invention discloses a three-dimensional deep soft soil composite foundation and a construction method. The three-dimensional deep soft soil composite foundation is composed of long soil cement reinforcement piles, short soil cement stirring piles and a composite reinforcement cushion layer, wherein each long soil cement reinforcement pile has an inverted-T type characteristic and is composed of a shallow layer and a deep layer, a CFG core pile is arranged in each deep layer, the diameter of the shallow layers is equal to that of the short soil cement stirring piles, and plain concrete reinforcement bands are arranged in gaps among the shallow layers of the long piles; the composite reinforcement cushion layer is composed of a rigid cushion layer, an intermediate horizontal reinforcement layer and an upper flexible cushion layer from bottom to top; interlaced staggering is adopted for pile layout of the composite foundation, and the construction sequence follows the principles that the long piles are constructed first and the short piles are then constructed, deep construction is conducted first and shallow construction is then conducted and construction is conducted from middle to the periphery. Research achievements such as the long piles, the short piles, rigid piles, flexible piles, a pile-net system and horizontal grates of multiple composite foundations are comprehensively considered, the settlement amount of the soil cement stirring piles can be effectively controlled, the bearing capacity of the foundation is reinforced, and post-construction reliability is high.
