Cableway pipe installation method
The invention provides a cableway pipe installation method which comprises the following steps: carrying out lofting on a stiff framework according to design coordinates, and welding a temporary support and a limiting stopper through angle steel; hoisting a cableway pipe to a mounting position, and pre-fixing and locating the cableway pipe; measuring the coordinates of the upper and lower outlet points of the cableway pipe for multiple times, and repeatedly adjusting the spatial position of the cableway pipe to reach the position of the designed coordinates; and after positioning is completed, fixing the cableway pipe to the stiff framework in a spot welding mode. According to the invention, the positioning principle of a three-dimensional space straight line is applied, the position path of the space straight line can be determined only by measuring the position paths of the two points on the straight line, the positioning method is rapid and simple, complex equipment and positioning calculation are not needed, the positioning precision is high, positioning and mounting of the cableway pipe are facilitated, and the influence on follow-up stay cable construction is reduced.
本申请提供一种索道管安装方法，包括以下步骤：根据设计坐标在劲性骨架放样，并用角钢焊接临时支撑和限位器；将索道管吊装至安装位置后并对该索道管进行预固定并定位；多次测量索道管上、下出口点的坐标，并反复调整索道管的空间位置，使其达到设计坐标的位置；定位完成后，将索道管点焊固定在劲性骨架上。本申请通过运用三维空间直线的定位原理，只需测定出直线上的两点的位路，则该空间直线的位路即被确定，该定位方法快捷简单，无需复杂的设备及定位计算，且定位精度高，便于索道管的定位安装，降低对后续斜拉索施工的影响。
