China News Agency, Wuhan, March 23 (reporters Xu Jinbo) 23rd press conference in Wuchang Riverside xujia shed see, Line 7 subway tunnel across the river South of the site of Wuhan is noisy machinery, the workers are sending well construction of shield machines. Wuhan municipal government officials said this marked China's first natural moat cross the Yangtze River highway-railway dual-purpose tunnel, is also the biggest tunnel project officially entered the comprehensive construction phase.
Male iron dual purpose Wuhan bridge and tunnel across the river is located in the Yangtze River Yangtze River, between Highway North of sanyanglu and South of Wuchang, Hankou xujia sheds, railways belonging to the Metro 7th line across the river.
According to builders – introduction to the project Chief Engineer Zhang Yi of Shanghai tunnel engineering company, male iron dual purpose Wuhan Yangtze River tunnel about two lines, 2599 m length, maximum depth of 40 meters. According to the planning of each tunnel is divided into three levels, upper level is smoke in highway tunnel road, Highway 3 traffic lanes in the Middle, the lower track 7th subway line and cable galleries, exhaust and escape.
Male iron dual purpose Wuhan Yangtze River tunnel 15.76 meters in diameter, equivalent to 5 stories tall, exceeded its section height and width has been set up in the city's first road tunnels and railway tunnels, is China's largest tunnel projects, tunnel shield machine for tunnel boring machine to complete the tunnel work. To this end, the construction company at a cost of 800 million Yuan, specially from Germany ordered two "large" shield machine, cutter nearly 16 meters in diameter, slated from Germany arrived in Wuhan. By then, the tunnel boring machine will go from Wuchang air shaft, crossing the Yangtze River to Hankow excavation, expected in February 2017 tunnel.
Wuhan Academy of social sciences, Li Chunyang experts pointed out that Yangtze River Bridge and the Yangtze River Bridge of Wuhan inner circle consisting of, is the core area of the central city of Wuhan, river-crossing traffic demand. Although Wuhan during this interval built China's first highway tunnel and the subway tunnel crossing the Yangtze River, but still can not meet the demand. While the relatively limited resources of the regional location of bridge and tunnel, this first male iron dual purpose built tunnel across the River, to conserve limited resources of bridge and tunnel, and promoting balanced economic and social development is of great significance in Wuhan.

中新社武汉3月23日电 (记者 徐金波)23日记者在武昌江边的徐家棚看到，武汉地铁7号线过江隧道江南工地正机器轰鸣，工人们正在进行盾构机始发井施工。武汉市政府官员称，这标志着中国首条穿越长江天堑的公铁两用隧道，同时也是国内第一大隧道工程正式进入全面施工阶段。
武汉公铁两用过江隧道位于长江大桥与长江二桥之间，其中公路连接江北汉口三阳路与江南武昌徐家棚，铁路属于地铁7号过江线。
据施工方——上海隧道工程公司项目总工张轶介绍，武汉公铁两用过江隧道设左右两条线，长度均为2599米，最大埋深达40米。根据规划每条隧道内部分为三层，上层是公路隧道排烟道，中间是公路3条车道，下层为地铁7号轨道线及电缆廊道、排烟道和逃生通道等。
武汉公铁两用过江隧道直径达15.76米，相当于5层楼高，其截面高度和宽度超过了该市业已建成的首条公路隧道和首条铁路隧道，是中国国内最大的隧道工程，一般的隧道盾构机无法完成该隧道盾构工作。为此，施工方耗资8亿元，特意从德国定制了两台“超大”盾构机，其刀盘直径接近16米，预计明年从德国运抵武汉。届时，盾构机将从武昌风井出发，穿越长江向汉口方向掘进，预计2017年2月隧道贯通。
武汉社科院专家李春洋指出，长江大桥与长江二桥组成的武汉内环线，是武汉中心城区的核心区，过江交通需求旺盛。尽管武汉在这个区间建成了中国首条穿越长江的公路隧道和地铁隧道，但仍然满足不了需求。同时该区域过江桥隧选址的资源比较有限，此番开建第一条公铁两用过江隧道，对节约有限的过江桥隧资源，促进武汉经济社会均衡发展等方面具有重要意义。(完)
