Pile and column integrated construction technology in tunnel pile method subway station
The invention discloses a pile-column integrated construction process in a hole-pile method subway station, and relates to the technical field of civil engineering. The pile-column integrated construction process comprises the following steps: pulping, and performing reverse circulation drilling to form a hole; hoisting and lowering a reinforcement cage; hoisting and lowering the steel casing; the steel casing and the reinforcement cage are installed; a lowering guide pipe is installed, and pile foundation concrete is poured; hoisting and positioning the steel pipe column by using a multifunctional steel pipe column mounting machine and a tool section; after the bottom of the steel pipe column is pre-stabilized, sand is filled outside the steel pipe column, and mortar is filled outside the steel casing; withdrawing the multifunctional steel pipe column mounting machine, and dismounting the tool section; mounting a steel pipe column top section; and pouring concrete in batches. According to the construction technology, the steel casing is additionally installed before the steel pipe column is hoisted, and the risk of hole collapse is avoided; slurry pumping drainage is conducted before the steel pipe column is installed, and buoyancy is prevented from affecting perpendicularity measurement and correction of the steel pipe column. The steel pipe column is arranged to be a conical sealing bottom and is integrally formed through one-time batch rapid pouring, and the construction quality is improved; the steel pipe column is provided with a conical sealing bottom and is integrally formed through one-time batch rapid pouring.
本发明公开一种洞桩法地铁车站中桩柱一体化施工工艺，涉及土木工程技术领域，制浆，反循环钻进成孔；吊装下放钢筋笼；吊装下放钢护筒；钢护筒和钢筋笼安装完成；安装下放导管并浇筑桩基混凝土；使用多功能钢管柱安装机及工具节吊装定位钢管柱；钢管柱底部预稳定后，钢管柱柱外填沙，钢护筒外填充砂浆；多功能钢管柱安装机撤出，拆除工具节；安装钢管柱顶节；批量浇筑混凝土。本发明中的施工工艺，钢管柱吊装前增加安装钢护筒，避免了塌孔的风险；钢管柱安装前先进行泥浆抽排，防止浮力影响钢管柱垂直度测量修正；钢管柱设置成锥形封底，整体一次批量快速浇筑成型，提高了施工质量；钢管柱设置成锥形封底，整体一次批量快速浇筑成型。
