Multi-pile type composite pile foundation structure, pile foundation and construction method of pile foundation
The invention provides a multi-pile type composite pile foundation structure, a pile foundation and a construction method of the pile foundation. The multi-pile type composite pile foundation structure comprises a first pile set, a second pile set and a third pile set, wherein the first pile set comprises a plurality of gravel piles at least surrounding the periphery of a whole pile foundation structure, the second pile set comprises a plurality of stiff composite piles, the stiff composite piles are distributed within the surrounding range of the first pile set, and the third pile set comprises a plurality of lap joint piles, the lap joint piles are at least distributed between the adjacent stiff composite piles, and the adjacent lap joint piles and/or the lap joint piles and outer core piles of the stiff composite piles are engaged with one another. According to the multi-pile type composite pile foundation structure, the first pile set is embedded into the liquefied foundation and can play a compaction role on the liquefied foundation, the stiff composite piles are adopted as the bearing piles to construct the second pile set, the lap joint piles are arranged in an engaged mode,the lap joint piles and the outer core piles of the stiff composite piles are arranged in an engaged mode, stress of the stiff composite piles can be shared, and the effect of improving the strengthand the bearing capacity of the stiff composite piles is achieved.
本发明提供一种多桩型复合桩基结构、桩基础、及其施工方法，包括：第一桩组，包括若干砂石桩，砂石桩至少围设在整体桩基结构的外围；第二桩组，包括若干劲性复合桩，劲性复合桩分布在第一桩组的包围范围之内；第三桩组，包括若干搭接桩，搭接桩至少分布在相邻劲性复合桩之间，相邻搭接桩之间和/或搭接桩与劲性复合桩的外芯桩之间相互咬合。第一桩组嵌入液化地基内能够对液化地基起到挤密作用，采用劲性复合桩做承载桩以构建第二桩组，搭接桩之间、搭接桩与劲性复合桩的外芯桩之间咬合设置，能够分担劲性复合桩受力，起到提高劲性复合桩的强度以及承载能力的作用。
