Pile body positioning device of miniature steel pipe pile and construction method
The invention belongs to the technical field of micro steel pipe pile construction, and particularly relates to a pile body positioning device of a micro steel pipe pile and a construction method. The pressing ring sleeves the stand column, is in sliding fit with the stand column and is located between the top plate and the base; the top plate is connected with the pressing ring through a spring; the positioning rod is connected with the base through a horizontally-arranged first rotating shaft, and the positioning rod is obliquely arranged downwards from the position close to the center of the stand column to the position away from the center of the stand column; the upper end of the positioning rod abuts against and is movably matched with the bottom of the pressing ring. The lower end of the positioning rod is located below the base and used for abutting against the inner wall of the upper end of the steel pipe. The centers of the first rotating shafts connected with the positioning rods are equal in elevation and are equal in distance from the axis L of the stand column. When the center of the upper surface of the circular level bubble coincides with the corresponding auxiliary mark and the circular level bubble indicates to be horizontal, the center of the top of the steel pipe is located at the designed theoretical position, and the steel pipe is vertical.
本发明属于微型钢管桩施工技术领域，具体涉及一种微型钢管桩的桩身定位装置及施工方法，圆形水准泡安装于顶板的上表面、且与立柱同轴布置；压环套设于立柱上、且滑动配合，压环位于顶板与底座之间；顶板与压环通过弹簧相连；定位杆与底座通过水平设置的第一转轴相连，定位杆从靠近立柱中心处向远离立柱中心处的方向倾斜向下布置；定位杆的上端与压环的底部相抵靠、且活动配合；定位杆的下端位于底座的下方，且用于与钢管上端内壁相抵靠；与每一根定位杆相连的第一转轴中心等高程、且与立柱轴线L的距离相等。当圆形水准泡上表面的中心处与相对应的辅助标识处相重合，以及圆形水准泡指示为水平时，钢管顶部中心位于设计的理论位置且钢管竖直。
