Post-pouring concrete construction method for underground vertical structural column through reverse building method
The invention relates to a post-pouring concrete construction method for an underground vertical structural column through a reverse construction method. The method specifically comprises the steps that a column head is constructed, and column body longitudinal steel bars and high-pressure grouting pipes are installed; installing other constructional steel bars; arranging a mortar reverse ridge; a column body formwork and a supporting system are installed, and vibrating holes and exhaust holes are formed; a concrete discharging pipe is installed, and vibration holes are formed for vibration; after the concrete vibrating holes in the top of the column body are closed, concrete vibrating is mainly conducted through the upper layer of concrete pouring openings and the vibrating holes; performing a non-pressure water passing test on the grouting pipe; concrete curing and form removal are conducted; performing ultrasonic detection on the interface position of the construction joint; performing high-pressure grouting; the construction joint interface is detected again through ultrasonic waves; constructing a column body; closing of the reverse building method floor holes is completed, and the temporary supports are dismounted one by one. Concrete is fully vibrated, the vibration efficiency is high, gas at the position of the construction joint is fully discharged, two construction joints are not generated, the construction cost is low, and the position of the construction joint is filled with materials safely and reliably.
本发明涉及一种逆作法地下竖向结构柱后浇混凝土施工方法，具体为：施工柱头，安装柱身纵向钢筋、高压注浆管；安装其他构造钢筋；设置砂浆反坎；安装柱身模板及支撑体系，设置振捣孔和排气孔；安装混凝土下料管，设置振捣孔进行振捣；柱身顶部混凝土振捣孔封闭后主要通过上一层混凝土浇筑口及振捣孔进行混凝土振捣；对注浆管进行无压通水测试；混凝土养护，拆模；对施工缝界面位置进行超声波检测；高压注浆；使用超声波再次检测施工缝界面；柱身施工；逆作法楼板洞口封闭完成，临时支撑逐一拆除。本发明混凝土振捣充分，振捣效率高，施工缝位置气体充分排出，不会产生2道施工缝，施工成本低、施工缝位置填充材料安全可靠。
