隧道开挖的方法,可分三种:矿山法(钻、爆法)、盾构法和掘进机法。目前我国铁路施工中,一般都采用矿山法,就是用钻眼爆破的方法进行开挖。随着机械化水平的发展,打眼使用液压多臂钻孔台车,功效大大提高,但安装炸药如何提高功效已成为迫切需要解决的问题,而现在所采用的是在解放牌汽车上搭一个大木架子,这种方法费工,费时,工人劳动强度大,与铁路建设的发展是极不相符的。因此,要求我们设计出 The tunnel excavation method can be divided into three types: mine method (drilling, blasting method), shield method and tunneling machine method. At present, in China’s railway construction, the mining method is generally adopted, that is, excavation is performed by blasting. With the development of the level of mechanization, the use of hydraulic multi-arm drilling trolleys has greatly improved the effectiveness. However, how to increase the effectiveness of explosive installation has become an urgent problem to be solved. Now, the adoption of a large wooden shelf on liberated vehicles has been adopted. This method is time-consuming, labor-intensive and labor-intensive. It is inconsistent with the development of railway construction. Therefore, we need to design
