Mounting and positioning method for underwater reinforcement cage of pile foundation
The invention relates to the technical field of pile foundation construction, and discloses a mounting and positioning method of a pile foundation underwater reinforcement cage, which comprises the following steps: at least three main reinforcements are reserved at the top of the reinforcement cage and are respectively connected with measurement positioning reinforcements, and the measurement positioning reinforcements and the connected main reinforcements are coaxially arranged; hoisting the reinforcement cage into the pile hole by the hoisting equipment; a reflecting part is arranged at the top of each measuring and positioning rib, the position coordinates of the reflecting part on each measuring and positioning rib are measured through a total station, the circumcircle center coordinates of three points are calculated through the three-point circle solving theorem, and the actual circle center coordinates of the reinforcement cage are obtained; and whether the deviation between the actual circle center coordinates of the reinforcement cage and the circle center design coordinates of the reinforcement cage is within an allowable error range or not is judged, and if the deviation exceeds the allowable error range, deviation correction is conducted on the reinforcement cage till the deviation is within the allowable error range. The installation accuracy of the underwater reinforcement cage is improved, deviation of pile foundation finished products is reduced, and the construction quality of circular structures such as pile foundations is improved.
本发明涉及桩基施工技术领域，公开了一种桩基水下钢筋笼的安装定位方法，包括以下步骤：在钢筋笼顶部至少预留三根主筋分别连接测量定位筋，测量定位筋与连接的主筋同轴设置；起吊设备将钢筋笼吊放至桩孔内；在每一测量定位筋的顶部设置反射件，通过全站仪测量每一测量定位筋上的反射件的位置坐标，通过三点求圆定理计算得出三点的外接圆心坐标，来获得钢筋笼的圆心实际坐标；判断钢筋笼的圆心实际坐标与钢筋笼的圆心设计坐标之间的偏差是否在允许的误差范围内，若超出允许误差范围，则对钢筋笼进行纠偏，直至偏差在允许的误差范围内。本发明提高水下钢筋笼的安装准确度高，减少桩基成品的偏差，提高桩基等圆形构筑物的施工质量。
