隧道仰拱机械设备配套快速施工技术

Discussion on Rapid Construction Method of a Complete Set of Mechanical Equipment for Tunnel Invert

本隧道以仰拱施工以机械化为出发点,采用可移动仰拱栈桥解决隧道施工中掌子面、仰拱、二次衬砌施工之间相互干扰的办法,并配置整体式移动模架、混凝土输送泵、布料管等机械设备,大大提高了仰拱施工工效,降低了施工成本,因此,该方法在隧道施工中具有推广意义。

The tunnel invert construction takes mechanization as the starting point and solves the problem of construction disturbance between rock tunnel face,invert and secondary lining using the mechanical equipment including mobile invert trestle,the whole movable frame,concrete pump,fabric tubes and so on,which greatly improves work efficiency of invert construction and reduces construction costs. Therefore,the method in tunnel construction is to promote meaningful.
