4 Shields can be steered by varying the thrust of the jacks from left side to right side or from top to bottom, thus varying the tunnel direction left or right or up or down. The jacks shove against the tunnel lining for each forward shove. The cycle of operation is forward shove ,line, muck, and then another forward shove. The shield used about 1955 on the third tube of the Lincoln Tunnel in New York City was 18 feet (5.5meters) long and 31.5 feet (9.6meters) in diameter. It was moved ahead 32 inches (81.2cm) per shove, permitting the fabrication of a 32-inch support ring behind it.
5 Sunken-tube tunnels. Where the riverbed subsoil is firm and the river current is not excessive,shore-fabricated tunnel sections can be towed over a prepared trench in the river bottom and suck into place to form a underwater tunnel. The first major prefabricated,floated,and sunken tunnel was the Detroit River Tunnel between Detroit and Windsor,Ontario.This vehicular tunnel was built in 1906-1910. The next important vehicular tunnel built by this method was the Posey Tube ,which was completed in 1928.It runs under a saltwater arm between Oakland and Alameda,Calif.Since then many other sunken-tube tunnels have been built under rivers and saltwater bodies,notbly the Transbay Tunnel between Oakland and San Francisco.
6 The cylindrical tunnel sections usually are made of steel in an onshore yard,Each section is about 300 feet (90 meters) long and 28 to 48 feet (8,5-14.6 meters) in diameter. After the openings at each end of a sevtion are closed with steel bulkheads, the tube is ready for launching in the manner of a ship . Once in the water, a section is ballasted with concrete until a minimum buoyancy is attained. Then the section is to the tunnel site. Before the arrival of the section,dredges and underwater excavators dig a trench to the proper depth of the tunnel.When the tube section is positioned precisely over its final location,additional concrete is added until the section sinks into prepared trench.All sections of the tunnel are transported and sunk in place in the same way.

4盾牌可以通过改变波束千斤顶推力的从左至右侧面或从上到下,从而改变了隧道方向向左或向右或上升或下降。杰克把对隧道衬砌每向前推。这个循环的运行是向前推,线条,粪,然后再向前推。使用了大约1955年盾的第三管在纽约林肯隧道是18英尺(5.5meters 315英尺)长,直径(9.6meters)。这是32英寸(81.2cm向前推,众说纷纭,每个制作出32英寸支撑环在它后面。

5 Sunken-tube隧道。在河床底土很坚决,这条河目前不过度,shore-fabricated隧道部分可被拖到一个准备在河里海沟底部和吸到适当的位置形成一个水下隧道。第一次重大的预制,浮在水面,和凹洞是长江隧道的底特律活塞,温莎,安大略之间。这是建立在1906-1910车载隧道。下一个重要的车载隧道建造了这一方法的波西管,在1928年建成的。它运行在盐水的手臂,加州奥克兰而孩童之间。从那时开始,许多其他sunken-tube隧道已经被建在河流和盐水的身体,notbly之间的Transbay隧道奥克兰和旧金山。

6这圆柱体隧道部分通常是钢制的在陆上院子里,每段大约300英尺(90米)长,28日至48英尺(8米),直径5-14.6。在每一端开口后的钢质舱壁sevtion是封闭的,与发射筒已经准备好了一艘船的方式。一旦进入水中,一节是摘要有碴与混凝土最低浮力是直到达到的。然后一节隧道的网站。这一节到来之前,疏通和水下挖掘机挖一条沟的适当深度的隧道。当管区段被放置在其最后的精确位置,具体是补充到部分沉没到准备了战壕。所有部分的隧道中沉没的地方将被以同样的方式来处理。
