Pipe truss jacking, unloading and installing method
The invention discloses a pipe truss jacking, unloading and installing method. The method comprises the following steps that an assembly type supporting system is installed; and a jacking and unloading device is manufactured, and the jacking and unloading device is installed on the assembly type supporting system. And hoisting the truss, and enabling the truss to fall on the jacking and unloading device. And aligning the trusses, and jacking or lowering the trusses through a jacking and unloading device. And tensioning the prestressed inhaul cable. And unloading the truss. The height of the pipe truss is adjusted through the jacking and unloading device, so that the position of a high-altitude butt joint opening is adjusted, and the hoisting and butt joint precision of the large-span pipe truss is improved.
本发明公开了一种管桁架顶升卸载安装方法，包括以下步骤：安装装配式支撑体系。制作顶升与卸载装置，并将顶升与卸载装置安装在装配式支撑体系上。桁架吊装，并使桁架落于顶升与卸载装置上。桁架对口，并通过顶升与卸载装置将桁架进行顶升或下放。预应力拉索张拉。桁架卸载。本发明通过顶升与卸载装置来调节管桁架高度，从而调整高空对接口位置，提升大跨度管桁架吊装对接精度。
