| 摘 要： | 随着码头建设逐步迈向深水化、外海化,带动上部预制梁板向大型化发展,但外海海况恶劣,传统起重船安装工艺无法保证精度。以青岛港董家口港区40万t矿石码头为例介绍外海精确安装500 t预制箱梁的整套施工工艺,主要包括采用海上塔吊、三维千斤顶与调梁扁担结合使用等。该工艺的成功实施,为海上大型预制箱梁的安装开辟了新思路。

| Abstract: | The tendency of deep water and offshore wharf construction leads to the enlargement of the upper precast beam slab.However,due to severe offshore conditions,the installation process by conventional rigging boat is insufficient in ensuring accuracy.Taking Dongjiagang 400 000 ton class mining wharf of Qingdao port for example,we introduce a complete set of accurate installation process for 500 t precast box girder at offshore,which mainly includes a combination adoption of offshore tower crane,3-D jack and beam-adjustment lever. |
