Steel pipe column in upper-soft lower-hard stratum subway station and construction method of subway station
According to the steel pipe column in the upper-soft lower-hard stratum subway station and the construction method of the subway station, a foundation reinforcement cage is safely connected with the bottom of the steel pipe column, and the steel pipe column and the foundation reinforcement cage serve as a whole and are lowered into a formed hole at the same time, so that the stability of the bottom foundation of the steel pipe column after construction can be effectively guaranteed; the construction space for independently constructing the bottom foundation of the steel pipe column is omitted, so that the size of the bottom foundation of the steel pipe column can be reduced, formed holes can be divided into upper large-diameter formed holes and lower small-diameter formed holes during hole forming, the volume of hard rock formed holes is reduced, the construction difficulty of hard rock hole forming is reduced, the hole forming efficiency is improved, and the construction cost is reduced. And the engineering investment is also saved. And meanwhile, the steel pipe column and the foundation reinforcement cage are put into the formed hole as a whole at the same time, the working procedure of installing a mechanical positioning head of the steel pipe column is omitted, the construction working procedure is simpler, and the construction efficiency of the steel pipe column can be further improved.
本发明涉及上软下硬地层地铁车站中钢管柱及地铁车站的施工方法，通过将基础钢筋笼与钢管柱底部安全连接，以及将钢管柱和基础钢筋笼作为一个整体同时下放至成孔内，可以有效保证钢管柱的底部基础施工后的稳定性，省去了单独施工钢管柱的底部基础的施工空间，进而可以减小钢管柱底部基础尺寸大小，使得在成孔时，可以将成孔分为上部大直径成孔，下部小直径成孔，减小了在硬岩成孔的体量，进而减小了硬岩成孔的施工难度，提高了成孔效率，也节省了工程投资。同时，将钢管柱和基础钢筋笼作为一个整体同时下放至成孔内，免去了安装钢管柱的机械定位头的工序，使得施工工序更加简单，能够进一步的提高钢管柱的施工效率。
