Hydraulic lifting type vertical large pipeline hoisting method
The invention discloses a hydraulic lifting type vertical large pipeline hoisting method, and relates to the technical field of pipeline hoisting. Comprising the following steps: selecting hoisting equipment and tools; positioning and paying off the pipeline in the pipe well; pipeline hoisting preparation; the first section of pipeline is pulled to the hoisting position, and the first section of pipeline is kept in a vertical state; the first section of pipeline is lifted and temporarily reinforced; the second section of pipeline is pulled to the hoisting position, and the second section of pipeline is kept in a vertical state; the first section of pipe and the second section of pipe are subjected to butt welding treatment; and the third section of pipeline is hoisted in place, butt welding is conducted on the third section of pipeline and the second section of pipeline according to the same method, and then lifting is conducted. The hydraulic jack anchorage device is adopted, reverse movement self-locking performance is achieved, the lifting process is quite safe, and a component can be reliably locked at any position in the lifting process for a long time. And during hoisting, a guide bracket and a temporary reinforcing device chain block are also arranged, so that various anti-falling mounting protection devices are formed, and the safety of hoisting operation is ensured.
本发明公开了一种液压提升式竖向大型管道吊装方法，涉及管道吊装技术领域。包括：吊装设备、工具选型；管井内管道定位放线；管道吊装准备；将第一节管道拉至吊装位置，使其保持竖直状态；将第一节管道提升并进行临时加固；将第二节管道拉至吊装位置，使其保持竖直状态；将第一节管、第二节管对口焊接处理；将第三节管道吊装就位，按照同样方法与第二节管进行对口焊接，之后提升。本发明采用液压千斤顶锚具，具有逆向运动自锁性，使提升过程十分安全，并且构件可以在提升过程中的任意位置长期可靠锁定。吊装时还有导向支架、临时加固装置手拉葫芦，形成多种防坠落安装防护装置，保证了吊装作业的安全。
