Rigidity adaptive prefabricated concrete sheet pile composite foundation and construction method
The rigidity-adaptive prefabricated concrete sheet pile composite foundation comprises prefabricated sheet pile structures, each prefabricated sheet pile structure comprises a first sheet pile, a second sheet pile, a third sheet pile, a fourth sheet pile, a seventh sheet pile and an eighth sheet pile, and a natural foundation soil body is arranged outside the structure formed by connecting and combining the multiple sets of prefabricated sheet pile structures through mortises and tenons. A unit internal soil body defined by the multiple sets of prefabricated plate pile structures serves as a unit reinforcing body of a natural foundation soil body and sinks into a foundation to form a composite foundation with a soil body retaining and restraining effect, hammering or static pressure pile sinking is adopted in the pile sinking process, and the soil body retaining and restraining effect is achieved along with continuous sinking of the multiple sets of prefabricated plate pile structures. When the lateral confinement unit structure is used, the natural foundation soil body and the unit internal soil body are compacted through compaction, each unit internal soil body defined by the multiple sets of prefabricated plate pile structures serves as a restraining structure, lateral confinement soil bodies in the plate piles can be restrained to prevent lateral deformation, and vertical sedimentation of the internal soil bodies of the lateral confinement unit structure is further reduced.
本发明公开了一种刚度适应型预制混凝土板桩复合地基，包括预制板桩结构，预制板桩结构包括一号板桩、二号板桩、三号板桩、四号板桩、七号板桩和八号板桩，多组预制板桩结构通过榫卯连接组合的结构外部设置有天然地基土体，利用多组预制板桩结构合围成的单元内部土体作为天然地基土体的单元增强体，沉入地基形成具有对土体围挡约束作用的复合地基，沉桩过程采用锤击或静压沉桩，随着多组预制板桩结构的不断沉入，天然地基土体和单元内部土体会受到挤密而密实，多组预制板桩结构合围形成的每个单元内部土体作为约束结构，可以约束板桩内部的侧限土体防止侧向变形，进一步减小侧限单元结构内部土体的竖向沉降。
