淮南—上海1 000 kV输变电工程全线按同杆双回钢管塔设计，钢管塔重型构件在河网泥沼地区运输存在许多困难，采取气囊和旱船是钢管塔重型构件在河网地区的可行运输方案。介绍了钢管塔重型构件河网地区的气囊和旱船运输方案及其配套机具的研制情况，以及2种运输方案的现场运输试验情况。

The design of double-circuit transmission lines of steel tube tower was used in the 1 000 kV UHV AC transmission line from Huainan to Shanghai. The transportation of steel tube tower’s heavy elements had some difficulties in the river network area. This paper introduced the transportation scheme of using gasbag and land boat, which was feasible for the steel tube tower’s heavy elements in the river network area. The development of outfitting tools for this transportation scheme was investigated, as well as the field tests.
