Stay cable installation method implemented by using cable-stayed hanging basket
The invention provides a stay cable installation method implemented by using a stay cable hanging basket, which comprises the following steps of: adjusting the position of the stay cable hanging basket, measuring and positioning the anchoring point position of a stay cable on the stay cable hanging basket, installing the stay cable, tensioning the stay cable for the first time, and installing the stay cable on the stay cable hanging basket; the installation position of a cable guide pipe is determined on the cable pulling hanging basket according to the position of the tensioned stay cable; mounting a cable guide pipe, and arranging a limiting mechanism at the opening of the cable guide pipe; mounting of steel bars and formworks is completed, beam section concrete is poured, and stayed cables are tensioned multiple times in a graded mode in the pouring process; after the strength of the concrete of the beam section meets the design requirement, the anchoring point of the stay cable is transferred to the poured beam section from the guy cable hanging basket, the stay cable is tensioned again, and stay cable installation of the current beam section is completed; and the steps are circulated until bridge construction is completed. The problem that the cable guide pipe is buried deeply and is difficult to adjust and position due to too much poured beam section concrete is solved, construction operation is convenient, and stress safety of the stay cable is guaranteed.
本申请提供一种利用牵索挂篮实施的斜拉索安装方法，其包括以下步骤：调整牵索挂篮的位置，在牵索挂篮上测量定位斜拉索的锚固点位置并安装斜拉索，对斜拉索进行第一次张拉，并根据斜拉索张拉后的位置在牵索挂篮上确定索导管的安装位置；安装索导管，并在索导管口处设置限位机构；完成钢筋和模板的安装，浇筑梁段混凝土，浇筑过程中对斜拉索进行分级多次张拉；待梁段混凝土的强度达到设计要求后，将斜拉索的锚固点由牵索挂篮转移至浇筑完成的梁段上，对斜拉索再次张拉，完成当前梁段的斜拉索安装；循环上述步骤直至桥梁施工完成。本申请解决了索导管因为被浇筑过多梁段混凝而掩埋较深难以调整定位的情况，施工操作方便，确保斜拉索的受力安全。
