马迹山港21#廊道拆除与安装工程
   
 

【工程简介】

    马迹山港位于浙江省嵊泗县泗礁岛西南约1.5km处的马迹山岛,距上海吴淞口约60海里,距南汇芦潮港约31海里,距舟山定海约74海里。本工程为满足环保要求,对腐蚀较为严重存在安全隐患的21#廊道实施整体更新改造,我司主要负责共计13跨钢结构桁架的整体拆除及安装施工。

    102日下午158分,我司完成马迹山港21号廊道上部结构报废更新项目中第3跨钢结构桁架的安装工作。至此,项目中难度最大、风险最大的钢桁架拆除安装工作全部完成。

 本次施工工期较紧,同时存在以下施工难点,首先,本次施工区域狭小,船机设备较多,拆除安装过程中进出频繁,保证船机设备进出正常是本工程的难点之一。其次,受潮汐和风浪影响,作业环境差。第三,部分施工区域水深不够,需要利用高潮位施工,时间把控是本工程的又一个难点。

   针对该工程难点,项目部人员不断改进拆除、安装技术,吊点计算力争无误,创新设计安装导向,使得整体工作效率提高50%以上,大幅度缩短了拆除、安装时间。
