Butt-joint construction method of super-deep underground continuous wall reinforcement cage lengthened sleeves
The embodiment of the invention discloses a butt-joint construction method of super-deep underground continuous wall reinforcement cage lengthened sleeves. According to the method, according to the design requirements and the construction technical specifications, rebars are pretreated, and preliminary blanking is achieved; a reinforcement cage is manufactured, the width of the reinforcement cageand the width of a notch which is being subjected to grooving are consistent, and a hoisting point is arranged on the reinforcement cage; the reinforcement cage is subjected to segmentation hoisting,and is divided into two L-shaped reinforcement cage bodies, and hoisting is performed through two crawler cranes; orifice butt joint is performed, the sleeves are selected for butt joint; and under the joint effect of lengthened sleeve right threads and locking nuts, orifice butt joint is achieved. The butt-joint construction method of the super-deep underground continuous wall reinforcement cagelengthened sleeves solves the problems that continuous wall reinforcement cages are large in butt joint construction difficulty and the period is long.
本发明实施例公开了一种超深地连墙钢筋笼加长套筒对接施工方法，所述方法为：根据设计要求及施工技术规范，对钢筋进行预处理，实现初步下料；制作钢筋笼，钢筋笼的宽度与正在成槽的槽口宽度一致，在钢筋笼上设置吊点；对钢筋笼进行分节吊装，分为两幅L型钢筋笼，利用两台履带吊进行吊装；进行孔口对接，选择套筒进行对接，采用加长套筒正丝和锁紧螺母共同作用实现孔口对接。本发明解决了连续墙钢筋笼对接施工难度大、周期长的问题。
