Construction method for underwater positioning of embedded rock-socketed foundation steel pipe pile
The construction method comprises the steps that a pair of main lifting lugs is arranged on the left outer side wall and the right outer side wall of the same horizontal plane of the upper portion of the steel pipe pile, a pair of limiting devices is arranged on the front outer side wall and the rear outer side wall of the steel pipe pile, and when the steel pipe pile is put down, positioning blocks are welded to the outer sides of the main lifting lugs and the limiting devices and used for horizontal positioning of the steel pipe pile; and a steel wire measuring rope is mounted at the pile top for controlling the pile top elevation, so that underwater positioning construction of the steel pipe pile is completed. Underwater positioning construction of the steel pipe pile can be achieved, the structure is simple and ingenious, construction is convenient, materials are saved, and construction procedures are simplified; lifting lugs and limiting devices are arranged on the outer side of the upper portion of the steel pipe pile, positioning blocks are welded during lowering construction, the plane position of the steel pipe pile can be accurately controlled, construction is easy and convenient, and operation is flexible; the steel wire measuring rope is adopted to directly measure the pile top elevation of the underwater steel pipe pile, underwater measurement is converted into overwater control, visual and controllable effects are achieved, and underwater construction and underwater measurement work are avoided.
本发明公开了一种用于植入嵌岩基础钢管桩水下定位的施工方法，在钢管桩上部同一水平面的左右外侧壁设置一对主吊耳，前后外侧壁设置一对限位装置，钢管桩下放时在主吊耳和限位装置的外侧焊接定位块用于钢管桩水平定位，在桩顶安装钢丝测量绳用于控制桩顶标高，从而完成钢管桩的水下定位施工。本发明能实现钢管桩水下定位施工，结构简单灵巧，施工方便，且节省了材料，简化了施工工序；在钢管桩上部外侧设置吊耳和限位装置并在下放施工时焊接定位块，可以精确控制钢管桩平面位置，且施工简便、操作灵活；采用钢丝测量绳可直接测得水下钢管桩桩顶标高，将水下测量转为水上控制，直观可控，避免了下水施工和水下测量工作。
