盾构外径为6262mm,总长8000mm,共有20组推进千斤顶。盾构总重450T,各主要部件的尺寸及重量如上表所示
五、施工方案
由于该盾构机尺寸大、重量重,需要分件、分批运输和吊装。本盾构机在大连装船后海运至深圳码头,然后再从码头转运至深圳香梅北站。由于散件的尺寸较大,通过对施工工艺、工序、经济性的综合分析后,我们决定采用260T履带式吊车作为主力,负责盾体、台车的下井和组装;用一台200汽车式液压吊车作辅助,负责协助后配套台车下井和组装并配合260T履带式液压吊车进行盾体翻身、吊装工作;在设备运输进入施工场地后,利用场地优势直接将设备卸车下井,这样既能满足施工技术和安全的要求,节约了施工成本。
六、施工作业要求及土建配合工作
1、吊装前将260T吊车工作位置的地基加固,如有必要可为履带吊工作位置铺设20厚钢板;
2、确保井口到井底的空间,四周井壁有12m×18m的空间;
3、各构件应加焊吊环〔按沈重维尔特设计要求及图纸〕;
4、在井口四周安装固定的防护栏及安全网;
5、在盾构机卸车、下井以及组装期间应设置施工禁区,其它无关人员不得入内;
6、施工现场内的运输车道应在8米宽以上;
7、如有改动见《吊装平面布置图》。
