Prefabricated slab pile composite foundation and construction method
The invention relates to the technical field of constructional engineering, and discloses a prefabricated slab pile composite foundation and a construction method. Rigid fence structures defined by wedge jointing of prefabricated slab piles serve as multifunctional reinforcement bodies of a natural foundation, and the prefabricated slab piles are sunken into foundation soil by adopting a hammeringor static pressure method to form a composite foundation together with the natural foundation and a gravel mattress layer arranged at the top of the natural foundation; the sunken piles and the wedgejoint rigid fence structures are used for confining, compacting and reinforcing soil bodies inside the sunken piles and the wedge joint rigid fence structures and between the sunken piles and the wedge joint rigid fence structures, so that the soil body bearing capacity is improved, and settlement deformation is reduced; due to the fact that the wedge joint rigid fence structures are large in lateral rigidity and high in stability, the capacity of resisting adverse influences of environmental changes and the anti-seismic property are improved; the prefabricated slab piles are in mutual wedgejoint in the pile sinking process, so that pile bodies are fully connected and jointly bear force; the prefabricated slab piles are flexibly wedged and combined, the shape can be adjusted according tothe upper load distribution characteristics, and the piles do not need to be arranged in the fence structure, so that the number of conventional pile-soil composite foundation reinforcement bodies can be greatly reduced, and the construction cost is reduced.
本发明涉及建筑工程技术领域，公开了一种预制板桩复合地基及施工方法，由预制板桩楔接围成的刚性围栏结构作为天然地基的多功能增强体，采用锤击或静压法将预制板桩沉入地基土中与天然地基及其顶部设置的碎石褥垫层共同构成复合地基；由沉桩、楔接刚性围栏结构对其内部及其之间的土体的围限、挤密和补强作用，提高土体承载力并减少沉降变形；因楔接刚性围栏结构侧向刚度大、稳定性强，提升抵抗环境变化不利影响能力及抗震性能；沉桩过程中预制板桩相互楔接，使桩体充分连结共同承载；预制板桩楔接组合灵活，能根据上部荷载分布特征调整形状且围栏结构内不必设桩，可大大减少常规桩土复合地基增强体的数量，降低工程造价。
