Composite light pile structure, manufacturing method, construction method and pile splicing method
The invention discloses a composite light pile structure, a manufacturing method, a construction method and a pile splicing method. The composite light pile structure comprises light soil and a composite reinforcement cage, the composite reinforcement cage comprises vertical geogrids arranged at intervals in the circumferential direction and annular geogrids arranged at intervals in the vertical direction, the light soil material is low in density and high in compression resistance, and the composite reinforcement cage utilizes the tensile capacity of the geogrids to play a role of stirrup under the action of pile top loads, so that a pile body has higher compressive capacity, and pile breaking or pile breaking is avoided; meanwhile, the composite reinforcement cage can prevent the composite light pile from cracking, and the structure reduces foundation in-situ effective stress by replacing foundation rock soil, can be used for balancing overlying load and reduces additional stress ofthe overlying load in a foundation; the structure is high in compressive strength, the foundation can be reinforced, the bearing capacity of the foundation is improved, the overlying load can be transmitted to a rock-soil stratum which is well laid through the structure, the additional stress of an existing building is prevented from being increased, and the purpose of controlling foundation deformation is achieved.
本发明公开了复合轻质桩构造、制作方法、施工方法和接桩方法，复合轻质桩构造包括轻质土和复合加筋笼，复合加筋笼包括沿周向间隔设置的竖向土工格栅和沿竖向间隔设置的环形土工格栅，轻质土材料低密度且高抗压，复合加筋笼利用土工格栅的抗拉能力，在桩顶荷载作用下起到箍筋作用，使桩体有更高的抗压能力，避免溃桩或断桩发生，同时复合加筋笼可防止复合轻质桩开裂，该结构通过置换地基岩土，降低了地基原位有效应力，其可用于平衡上覆荷载，达到减小上覆荷载在地基中的附加应力，该构造抗压强度高，能加固地基，提高地基承载力，通过该构造还可将上覆荷载传递至下卧较好的岩土地层，避免既有建筑物附加应力增大，实现控制地基变形的目的。
