19世纪初,英国准备在泰晤士河上修建一条水下隧道,但由于土质松软极易塌方,因此给施工带来很大困难。负责工程指挥的工程师布鲁尔为此焦急万分,但一时也未找到有效的解决方法。有一天,布鲁尔外出散步,偶然间发现一只昆虫在其外壳的保护下使劲向一棵树的皮里钻。布鲁尔被此情景吸引住了。随后他想,按照这种方法改变一下掘进方式是否可行呢? 于是他创造性地提出了一种新的掘进方案:先把空心柱打进河底,以此作为“构盾”,在构盾的保护下开挖。实践证明,这种方法是行之有效的。这样一来,布鲁尔就发明了一种新型施工方法——构盾式掘进法,被世界各国普遍采用。
At the beginning of the 19th century, Britain was going to build an underwater tunnel on the Thames. However, due to its extremely soft soil and its easy collapse, it brought great difficulties to the construction. Brewer, engineering engineer in charge, was anxious for this but did not find an effective solution for a while. One day, Brewer went out for a walk, accidentally finding an insect in the shell under the protection of hard to drill a tree's skin. Brewer is attracted to this scene. Then he thought that it would be feasible to change the way of heading according to this method. Then he creatively proposed a new excavation plan: he first hit the hollow pillars into the bottom of the river and used it as a “structural shield” Excavation under protection. Practice has proved that this method is effective. As a result, Brewer invented a new type of construction method - shield tunneling method, is widely used in all countries in the world.
