论述铁道部第三工程局修建黎塘-钦州地方铁路飞龙深水大桥,研制和使用水上浮吊施工的做法和经验。对水上浮吊的组成结构、拼装和使用方法作了详细阐述。通过使用,浮吊与缆索吊相比,具有投资少、行动灵活、起重力大、作用范围大、安全性能较好、检修工作量和费用小等优点。使用浮吊是深水大桥施工中,满足施工现场起重、运输工作的一种理想方案,可供借鉴。

The Fei long Bridge on the Li tang-Qinzho u local raiway was bui lt by the Thi rd Engineering Bureau o f MOR. The const ructio n method and the ex periences fo r bui lding this bridg e w ithin the deep w ater by using the f loating crane are described in this paper. The st ructural compo sition of the floa ting crane and i ts assembly and application methods a re expounded. Th roug h the applica tion and by compari sio n wi th the cable crane, the f loating cra ne has the follow ing adva ntages, such as the low inv estment , flexible movement , hig h hoisting capaci ty , wide action scope, etc, as w el l as better safety and low maintenance period and cost. The flo ating cra ne is an idea scheme used in the co st ruction o f bridge w ithin the deep w ater to fulfi ll the lif ting and t ranspo rt w o rks in the co nst ructio n si te.
