Mounting and positioning method for curve unbonded prestressed tendons of underground diaphragm wall

The invention provides a method for installing and positioning curve unbonded prestressed tendons of an underground diaphragm wall. According to the installing and positioning method for the curve unbonded prestressed tendons of the underground diaphragm wall, a pre-drawn linear installing and positioning map of the curve unbonded prestressed tendons of the underground diaphragm wall serves as a construction drawing for installing and positioning the curve unbonded prestressed tendons, and accurate installing and positioning construction of the curve unbonded prestressed tendons is conducted in cooperation with corresponding construction steps. And it is effectively ensured that the linear positioning of the curve unbonded prestressed tendons of the underground diaphragm wall is accurate and remains unchanged during the installation, reinforcement cage hoisting into a groove and underwater concrete pouring. 本发明提供了一种地下连续墙曲线无粘结预应力筋的安装定位方法，所述地下连续墙曲线无粘结预应力筋的安装定位方法基于预先绘制的地下连续墙的曲线无粘结预应力筋线形安装定位图作为曲线无粘结预应力筋安装定位的施工图，配
