| 揭秘吊装带在管道行业的应用 Reveal the application of the condole belt in the pipeline industry 1、管道下管：采用吊装带以免伤及管身混凝土。吊装带吊装前应找出管体重心，做出标志以满足管体吊装要求。下管时应使管节承口迎向流水方向。下管、安管不得扰动管道基础。 Pipe: use a sling to avoid damage and concrete. The lifting of the sling should find the weight of the tube and make the mark to meet the requirements of the pipe. The pipe socket should be held in the direction of the flow line. The lower tube and the tube shall not disturb the foundation of the pipe. 2、稳管：管道就位后，为防止滚管，应在管两侧适当加两组四个楔形混凝土垫块。管道安装时应将管道流水面中心、高程逐节调整，确保管道纵断面高程及平面位置准确。每节管就位后，应进行固定，以防止管子发生位移。用吊装带稳管时，先进人管内检查对口，减少错口现象。管内底高程偏差在±l0mm内，中心偏差不超过l0mm，相邻管内底错口不大于3mm。 Stabilisation pipe: after the pipe is in place, two sets of four wedge-shaped concrete blocks should be added to the two sides of the tube to prevent the pipe. When the pipe is installed, the center of the water surface of the pipe should be adjusted to make sure that the height of the pipe and the plane position are accurate. After each pipe is in position, it should be fixed to prevent the pipe from moving. When using a sling to hold the pipe, the advanced man will check the right and wrong mouth. The height deviation in the inner tube is not greater than l0mm in the plus or minus l0mm, and no more than 3mm in the adjacent tube. |
