全断面岩石隧道掘进机(Full Face Hard Rock Tunrnel Boring Machine),简称掘进机或TBM。全断面岩石掘进机与传统钻爆法相比,优势如下:1、快速;2、优质;3、经济;4、安全;5、环保。TBM工作原理:步进时,TBM后支腿和举升油缸收起,主机压在弧形滑轨上,通过步进推进油缸向前推动底护盾,利用底护盾与弧形滑轨间的摩擦力小于弧形滑轨与混凝土底板之间的摩擦力,便可推动TBM向前步进,后配套可随TBM主机一起在铺设的轨道上前行。
Full Face Hard Rock Tunnel Boring Machine (Full Face Hard Rock Tunrnel Boring Machine), referred to as road boring machine or TBM. Full-face rock drilling machine compared with the traditional method of drilling and blasting, the advantages are as follows: 1, fast; 2, high quality; 3, economy; 4, safety; TBM working principle: When stepping, TBM support leg and lifting cylinder stowed, the host pressure on the arc slide, pushing forward by stepping cylinder forward shield at the bottom, the use of shield between the arc and the arc between Of friction less than the friction between the arcuate slide and the concrete floor can push the TBM forward and the back kit can be advanced along with the TBM host on the laid track.
