　　近日，嵊泗至定海公路普陀鲁家峙至东港公路工程海底隧道盾构机——“中铁R148号”在中铁装备集团高端装备再制造中心完成安装调试，并顺利通过验收。“中铁R148号”为国内目前最大直径再制造盾构机。

　　“中铁R148号”原为法国造“NFM06号”盾构机，为气垫式泥水平衡盾构机，主要由主机、驱动、辅助设备系统和5节拖车等组成，总长约91米，总重量超过1100吨，开挖直径为11.7米。“中铁R148号”投用后，将为鲁家峙至东港公路工程盾构段掘进增添新动力。

　　鲁家峙至东港公路工程盾构施工段为双洞海底隧道，左洞长785米，右洞长777米，由鲁家峙工作井始发，下穿沈家门渔港后，到达沈家门侧工作井。目前，盾构始发井已完成80%的工程量，盾构区泥水处理设备完成安装调试，盾构管片预制已累计完成58环。下一步，施工方将重点做好相关设备、资料的交接，及拆机、运输、工地组装、工地调试工作，为盾构段顺利始发做好相关准备。
