Urban subway station steel pipe column construction method adopting hole-pile method
The invention relates to the technical field of subway construction, and provides an urban subway station steel pipe column construction method adopting a hole-pile method. The urban subway station steel pipe column construction method comprises the following steps that (1) preparation before construction is achieved; (2) a foundation reinforcement cage is constructed; (3) a positioning device is mounted; (4) the foundation reinforcement cage is poured with concrete; (5) steel pipe columns are mounted; (6) an in-column reinforcement cage is mounted; (7) secondary concrete pouring is conducted on the foundation reinforcement cage; and 8) the concrete is poured in a steel pipe column. According to the urban subway station steel pipe column construction method adopting the hole-pile method, the technical problems of precise positioning of the steel pipe column under a hole pile in a narrow pilot tunnel space, transportation and hoisting of the steel pipe column, in-column concrete pouring quality control and the like are solved, the site construction progress is accelerated, and meanwhile the construction quality and construction safety of the steel pipe column are guaranteed; and a certain basic technical support is provided for subway underground excavation hole pile method station steel pipe column construction under subsequent similar working conditions.
本发明涉及地铁施工技术领域，提供了一种城市地铁洞桩法车站钢管柱施工方法，包括步骤有：1)施工前准备；2)基础钢筋笼施工；3)安装定位装置；4)混凝土浇注基础钢筋笼；5)安装钢管柱；6)安装柱内钢筋笼；7)二次混凝土浇注基础钢筋笼；8)钢管柱内混凝土浇注。本发明解决了导洞狭小空间内孔桩下钢管柱精准定位、钢管柱运输与吊装、柱内混凝土浇筑质量控制等技术难题，加快了现场施工进度的同时保证了钢管柱施工质量及施工安全，为后续类似工况下地铁暗挖洞桩法车站钢管柱施工提供一定的基础技术支持。
