一种模仿蚯蚓似的新奇的隧道工程系统,在伦敦已首次运用,并获得了英国国家核研究开发公司和“新土木工程师”所颁发的革新竞赛奖。该联合隧道系统像一条蚯蚓,是利用土壤的摩擦阻力来推进。有三个相邻的管段作为隧道衬砌,用一个千斤顶顶开中间的节点之一,从而使一个管段移向土中反抗其他两段上较大的土壤摩擦力。该联合隧道系统是Marcon国际有限公司的Mike Riehardon发明的,并经John,Mowlem和两个公司的改进。它可用在常规的隧道施工法或推进钻进法所能用的任何地方,并比传统方法优越。特别在有困难的情形。例如,面层、有沉陷或在隧道四周的围岩有剪切位移而无法用传统方法的地方。
A novel tunneling system that mimics earthworms has been used for the first time in London and won an Innovation Award from the National Nuclear Research Corporation and the New Civil Engineer. The joint tunnel system is like an earthworm that uses the frictional resistance of the soil to propel it. There are three adjacent pipe sections acting as tunnel linings with one jack jacking one of the middle nodes so that one pipe section moves towards the soil against the larger soil friction on the other two sections. The joint tunnel system was invented by Mike Riehardon of Marcon International Limited and was refined by John, Mowlem and two companies. It can be used anywhere conventional tunneling or propulsion drilling can be and is superior to traditional methods. Especially in difficult situations. For example, the surface layer, subsidence, or where the surrounding rock around the tunnel has shear displacement can not use the traditional methods.
