Upright column pile of YCMG construction method composite precast pile and construction method of upright column pile
The invention discloses a stand column pile of a YCMG construction method composite precast pile and a construction method of the stand column pile, and belongs to the technical field of pile foundations. The stand column pile comprises the prefabricated pile, the latticed column, the cement soil pile and the rigid expansion body connecting piece, the pile hole construction noise is low, earth cutting is not needed, slurry is not needed, and environment friendliness is achieved; the precast pile is installed at the bottom of the pile hole, the cement-soil pile is formed on the periphery of the precast pile, and the concrete wrapping the reinforcement cage connecting piece is poured at the joint of the precast pile and the latticed column to form the rigid expansion body connecting piece, so that the problem of poor shear resistance of the connecting joint is solved, and the bearing capacity of the stand column pile is greatly improved. Compared with an existing stand column pile, the construction method is simple, the construction efficiency is improved by 200%-300%, the quality and safety of the joint of the precast pile and the latticed column are reliably guaranteed, the pile foundation bearing capacity of the stand column pile is improved by 10%-50%, green and pollution-free construction is achieved, the construction cost is greatly reduced, and remarkable economic and social benefits are achieved.
本发明公开了一种YCMG工法复合预制桩的立柱桩及其施工方法，属于桩基技术领域。本发明的立柱桩包括预制桩、格构柱、水泥土桩和刚性扩大体连接件，桩孔施工噪音小，且无需挖土，没有泥浆，绿色环保；预制桩安装至桩孔的孔底，并在预制桩的周边形成水泥土桩，在预制桩和格构柱的交接处浇注包裹在钢筋笼连接件的混凝土形成刚性扩大体连接件，使得连接节点的抗剪性差的问题得到解决，立柱桩的承载力得到大幅提高。与现有立柱桩相比，施工方法简单，施工效率提高200％～300％，预制桩和格构柱交接处的质量及安全得到可靠保证，立柱桩桩基承载力提高10％～50％，实现了绿色无污染施工，施工成本得以大幅度降低，有显著的经济和社会效益。
