(接上期)梁体的运输、存放移动重物的可能方案有:空中运输方案,如利用直升飞机起吊、运输;水中运输方案,如利用船舶装载运输;陆地运输方案,如龙门吊机起吊、运输等。由于预应力混凝土箱梁的重量大,目前条件下采用空中运输的方案不可能实现。垂直移动重物的方案有:龙门吊机提升、汽车或履带吊机等提升、千斤顶提升、抽水注水或涨潮落潮升降等。水平移动重物的方案有:轮式台车运输,如轮胎式、轮轨式、履带式台车;滚辊式台车运输,如气囊,钢滚筒;滑移式台车运输;水上船舶运输等。
(Continued) The transport and storage of moving heavy objects may include: air transport solutions such as lifting and transporting by helicopter; underwater transport solutions such as ship loading and transport; land transport solutions such as gantry crane lifting, Transport and so on. Due to the heavy weight of prestressed concrete box girders, it is not possible to implement air transport solutions under current conditions. Vertical weight of the program are: gantry crane upgrade, car or crawler cranes and other upgrades, lifting jack, pumping water or ebb and flow ebb and flow. The scheme for moving heavy objects horizontally is as follows: wheeled trolley transport, such as tire type, wheel rail type, tracked trolley; roller trolley transport, such as air bag, steel drum; sliding trolley transport; Wait.
