盾构机由于其一次成洞的特点得到了广泛的应用,但同时这个特点也给维修带来了很大的麻烦,特别因其产品系列难以形成固定的规格,导致一些设计和元件的成熟度不够,这也增加了发生故障的概率。下面,向读者介绍世界上最大直径的盾构机在美国西雅图维修的历程。背景介绍美国华盛顿州的SR99公路是一条州路,相当于我国的省道,在西雅图市中心的路段以双层高架桥的形式穿过,是西雅图市中心区域两条南北方向主干道之一。由于已建成约60年,
Shielding machine due to its once-hole features have been widely used, but this feature also brought great trouble for maintenance, especially because of its product line is difficult to form a fixed specification, resulting in some of the design and component maturity Not enough, which also increases the probability of failure. Next, introduce readers to the world’s largest diameter shield machine maintenance in Seattle, the United States.
