Embodiment Construction
[0027] Specific embodiments of the present invention are described in detail below to facilitate a further understanding of the present invention.
[0028] The new seismic isolation composite foundation of this embodiment, from top to bottom, is: superstructure 8, raft 7, multi-layer seismic isolation strengthening cushion, pile 1; the multi-layer seismic isolation strengthening cushion is sequential from top to bottom It is composed of: fiber-solidified soil layer 6, double-layer wrapped geotechnical composite crushed stone layer 3-5, and solidified soil layer 2.
[0029] First, prefabricated steel pipe piles and rafts;
[0030] Then the prefabricated piles are driven in. The piles are made of steel pipe piles. The piles are arranged in a square shape. The pile length is determined according to the specific soil conditions. A certain height is reserved for the top surface of the foundation and buried in the solidified soil layer. The reserved height of the pile top accounts ...
