Positioning device and method for construction of steel pipe columns of subway station through cover and excavation top-down method
The invention discloses a positioning device and method for construction of a steel pipe column of a subway station through a cover and excavation top-down method. The positioning device comprises a fixed track beam, a transverse moving track beam, a longitudinal moving track beam, a positioning pulley assembly and a positioning instrument. The two fixed track beams are parallel and fixed at intervals, and the pair of transverse moving track beams are installed on the two fixed track beams through the positioning pulley assemblies and are perpendicular to each other. The pair of longitudinal moving track beams is installed on the two transverse moving track beams through the positioning pulley assemblies and is perpendicular to the two transverse moving track beams. Meanwhile, the positioning pulley assembly in the transverse moving track beam is located on the inner side of the positioning pulley assembly in the fixed track beam; the positioning instrument is placed on the pile top or fixed above the steel pipe column; the position indicator projects towards the center of the steel pipe column, the position of the steel pipe column is adjusted by moving the transverse moving track beam and the longitudinal moving track beam, and the pile center coincides with the steel pipe column center. According to the invention, the steel pipe column can be quickly and conveniently positioned.
本发明公开了一种盖挖逆作法地铁车站钢管柱施工定位装置及方法，定位装置包括固定轨道梁、横向移动轨道梁、纵向移动轨道梁、定位滑轮组件及定位仪；两个固定轨道梁平行、间隔固定，一对横向移动轨道梁通过定位滑轮组件安装在两个固定轨道梁上，且二者互相垂直；一对纵向移动轨道梁通过定位滑轮组件安装在两个横向移动轨道梁上，且二者互相垂直；同时横向移动轨道梁内的定位滑轮组件位于固定轨道梁内的定位滑轮组件内侧；定位仪放置在桩顶或固定在钢管柱上方；定位仪向钢管柱中心投射，通过移动横向移动轨道梁、纵向移动轨道梁调整钢管柱位置，使得桩中心与钢管柱中心重合。本发明能够快速、方便的对钢管柱进行定位。
