目前的隧道衬砌混凝土是用混凝土搅动卡车从混凝土预拌工厂运来的,坑道内运输使用的是混凝搅动轨道小车。向模板内浇注时一般都使用压气式螺旋压送桩或拌运压力灌注车,但是如果在长大隧道内或寒冷地区,由于搬运距离过长和产生冻结,而很难设置混凝土预拌工厂时,也有采用干料分拌系统将干料运到工作面上后掺入水和混和剂,再搅拌浇注的,但是 The current tunnel lining concrete is delivered from a concrete ready-mix plant using a concrete mixing truck that uses a coagulating and agitating rail car. Pouring into the formwork usually involves the use of compressed-air spiral piles or mixed-pressure pours into the formwork. However, if it is difficult to set up the concrete ready-mix plant due to the long moving distance and the freezing in long tunnels or cold areas , But also the use of dry material mixing system to the dry material transported to the face after mixing water and mixing agent, and then mixing pouring, but
