Multi-level expanding body rigid composite pile, construction equipment and construction method
The invention discloses a multi-level expanding body rigid composite pile, construction equipment and a construction method, and belongs to the technical field of pile foundations. The multi-level expanding body rigid composite pile comprises a stirring pile or a jet grouting pile and a rigid pile arranged in the stirring pile or the jet grouting pile. A multi-layer branch expanding body mixing pile or a jet grouting pile is creatively combined with a rigid pile of a multi-layer rigid expanding body to form a multi-node branch type cement mixing pile or a high-pressure jet grouting pile rigid composite pile, and a plurality of layers of rigid branches which can be radially expanded and extend into the mixing pile or the jet grouting pile are utilized; the side wall friction resistance and the end bearing capacity of a soil body are fully improved, and the effect of greatly improving the bearing capacity and the pulling resistance of the pile is achieved; meanwhile, soil taking construction is not needed, outward transportation of earthwork is avoided, cost is saved, mud cannot be generated, and construction is more environmentally friendly; the rigid pile of the multi-layer rigid expanding body can be a factory precast pile, the quality is reliable, and the pile forming quality of the multi-layer expanding body rigid composite pile is guaranteed.
本发明公开了一种多层级扩大体刚性复合桩、施工设备及施工方法，属于桩基技术领域。本发明的多层级扩大体刚性复合桩，包括搅拌桩或旋喷桩和置入搅拌桩或旋喷桩内的刚性桩。创造性地将多层支盘扩大体搅拌桩或旋喷桩与多层刚性扩大体的刚性桩相结合，形成多节点支盘式的水泥搅拌桩或高压旋喷桩刚性复合桩，利用多层可径向展开并伸入搅拌桩或旋喷桩的支盘扩大体内的刚性支盘，充分提高了土体侧壁摩阻力以及端部承载力，达到大幅度提高桩的承载力和抗拔力的作用；同时采用不需要取土施工，避免了土方外运，节约了成本，也不会产生泥浆，施工更加环保；多层刚性扩大体的刚性桩可以为工厂预制桩，质量可靠，保证了多层级扩大体刚性复合桩的成桩质量。
