摘要
镇海-舟山500kV线路工程(镇舟线副跨)主要包括沥港、桃夭门、响礁门3处大跨越,共8基基础,塔位均错落分布在各个海岛上,气候条件恶劣,潮汐变幻莫测,水流涌动频繁,交通不发达。本次工程借鉴以往大跨越跨江、跨海展放引绳施工经验,针对海岛特殊地形、水文条件,应用登陆艇牵引、张力机带张力展放的施工技术,成功地将φ22迪尼玛引绳全过程不落水展放过海,保证了工程架线的顺利实施,对以后大跨越施工架线方案选择具有重要的指导作用。
The Zhenhai-Zhoushan 500 kilovolt line project (Zhenzhou Line Subspan) mainly consists of three large-span crossings, namely,Ligang,Taoyumen and Xiangyoumen,with a total of 8 foundations.The towers are scattered on various islands,with harsh climate,unpredictable tides,frequent flow of water and underdeveloped traffic.This time,drawing lessons from the past construction experience of long-span river-crossing and sea-crossing rope-drawing,aiming at the special terrain and hydrological conditions of the island,applying the construction technology of landing boat traction and tension machine belt tension-spreading,the whole process of the 22 Dinima rope-drawing is successfully extended across the sea without falling into the water,which ensures the smooth implementation of the project line-drawing and plays an important guiding role in the selection of the scheme of long-span construction line-drawing in the future.
