Composite foundation bearing structure for placing prefabricated pile into cement-soil mixing pile
The invention discloses a composite foundation bearing structure for placing a prefabricated pile into a cement-soil mixing pile. According to the composite foundation bearing structure for placing the prefabricated pile into the cement-soil mixing pile, the cement-soil mixing pile is constructed according to the distribution range of the prefabricated pile on the bottom face of a cushion cap or raft foundation or box type foundation of a building foundation and the prefabricated pile center position, an auxiliary material and/or an additive are/is mixed in cement-soil curing agent preparationslurry of the cement-soil mixing pile, then a reinforced concrete prefabricated pile is placed into the corresponding cement-soil mixing pile, and the top of the prefabricated pile is provided with areinforced concrete cushion cap or a raft foundation or a box type foundation. By means of the composite foundation bearing structure, the cement-soil mixing pile and the reinforced concrete prefabricated pile are organically combined, physical and mechanical properties of foundation soil are improved by mixing pile construction, pile sinking construction of the reinforced concrete prefabricatedpile is facilitated, and the soil compaction effect on the site foundation can be significantly reduced, standard values of side resistance and end resistance of the prefabricated pile are increased,and the bearing capacity characteristic value of the foundation soil treated by the mixing pile is enhanced, so that the composite foundation bearing capacity is improved.
本发明公开了一种在水泥土搅拌桩中置入预制桩的复合地基承载结构，根据建筑地基基础的承台或筏板基础或箱形基础底面预制桩分布范围及预制桩中心位置施工水泥土搅拌桩，水泥土搅拌桩的水泥土固化剂制备浆液中掺入辅料和/或外掺剂；然后在相应的水泥土搅拌桩中置入钢筋混凝土预制桩，预制桩顶设置钢筋混凝土承台或筏形基础或箱形基础。本发明的复合地基承载结构将水泥土搅拌桩和钢筋混凝土预制桩有机地结合起来，通过搅拌桩施工改善了地基土的物理力学性质，利于钢筋混凝土预制桩的沉桩施工，并可显著减少对场地地基的挤土效应，增加预制桩的侧阻力、端阻力标准值，增强搅拌桩处理的地基土承载力特征值，从而提高复合地基的承载力。
