Integrated construction method for independent bearing platform and pile foundation
The invention relates to the technical field of constructional engineering, in particular to an integrated construction method for an independent bearing platform and a pile foundation. A bearing platform groove is excavated according to the designed bearing platform size, and a slurry groove is excavated in one side of the bearing platform groove; embedding a steel template, cutting a round hole aligned with the pile position in the bottom of the steel template, and forming a slurry overflow hole in the side surface of the steel template on the right side; cohesive soil is backfilled around the steel formwork; drilling in place by a pile machine; a drilling machine drills to a designed depth; concrete is pumped underwater, when the top face of the concrete is poured to the lower edge of the grout overflow hole, the grout overflow hole is closed, the concrete continues to be poured, and the concrete face is flush with the upper surface of the steel formwork; after the free surface of the concrete is flush with the upper surface of the steel formwork, a reinforcement cage system which is formed by integrating and binding the pile foundation and the bearing platform foundation is hoisted in, and column steel bars are fixed before initial setting of the concrete of the bearing platform foundation; the set-shaped steel formwork is dismantled; and backfilling and maintaining. The concrete pile foundation and the bearing platform foundation are integrally constructed, the construction period is greatly shortened, and the construction cost is saved.
本发明涉及建筑工程技术领域，具体为一种独立承台与桩基础一体化施工方法，测放桩位，打孔；根据设计承台尺寸开挖承台槽，在承台槽一侧开挖泥浆槽；埋设定型钢模板，钢模板底部切割与桩位对齐的圆孔，右侧钢模板侧面开溢浆孔；钢模板四周回填粘性土；桩机就位开钻；钻机钻至设计深度；水下泵送混凝土，混凝土顶面灌至溢浆孔下缘时，封闭溢浆孔，继续灌入混凝土，使混凝土面与钢模板上表面齐平；混凝土自由面与钢模板上表面齐平后，吊入桩基础与承台基础集成到一起绑扎的钢筋笼系统，在承台基础混凝土初凝前固定柱体钢筋；拆除定型钢模板；回填及养护。本发明将混凝土桩基与承台基础一体化施工，极大缩短了工期，节省施工成本。
