第二航务工程局一处汉阳预制场从1978年5月投产使用水垫水平搬运40吨T型梁的运输工艺以来,经两年的运用,积累了一定的经验,确认水垫搬运技术具有设备简单、操作方便、运输稳定安全等显著优点。将此方案与原设计的平车—钢轨道运输方案比较,节约钢材92％、水泥76％,基建直接费用降 Second Hailing Engineering Bureau, a Hanyang prefabricated yard put into operation in May 1978 from the use of water mats horizontal transport of 40 tons of T-beam since the transport process, after two years of use, has accumulated some experience to confirm the water mats handling technology with equipment Simple, easy to operate, stable transportation and other significant advantages. Comparing this plan with the original design of flat car - rail transportation scheme, saving 92% of steel, 76% of cement, direct infrastructure cost reduction
