Rapid tunneling method and device suitable for full-soil hole, mudstone and sandstone tunnel
The invention provides a rapid tunneling method and device suitable for a full-soil hole, mudstone and sandstone tunnel. The rapid tunneling method comprises the following steps that S1, a grooving mechanical gripper is used for grooving along the edge of a tunneling tunnel face of the tunnel, and the outer edge of a groove is the designed outer edge of the tunnel; an advance support guide pipe is driven into the weak position of the excavation inner wall of the tunnel, and grouting is conducted; s2, the excavator bucket is used for excavating other positions of the tunneling tunnel face; s3, soil is loaded on a soil conveying belt through an excavator bucket, and the soil is conveyed to the outside of the tunnel through a transport vehicle; s4, a first lining layer is constructed on the inner wall of the tunnel; s5, a second lining layer is constructed on the inner wall of the first lining layer; through the steps, rapid tunneling of a full-soil hole, a mudstone tunnel and a sandstone tunnel is achieved. The tunneling tunnel face is of an inclined structure, and the top of the tunneling tunnel face inclines towards the tunneling direction. By adopting the scheme that the groove is firstly dug in the edge of the tunnel face, and then the other part of the tunnel face is dug, the step-by-step core soil reserving excavation method can be achieved, and the construction efficiency is improved.
本发明提供一种适用于全土洞、泥岩及砂岩隧道的快速掘进方法及装置，包括以下步骤：S1、以挖槽机械爪沿着隧道的掘进掌子面边缘挖槽，槽的外缘为隧道的设计外缘；在隧道开挖内壁软弱的位置打入超前支护导管，并注浆；S2、以挖斗开挖掘进掌子面的其余位置；S3、以挖斗将泥土装载在泥土输送带上，将泥土以运输车输送至隧道外；S4、在隧道的内壁施工第一衬砌层；S5、在第一衬砌层的内壁施工第二衬砌层；通过以上步骤实现全土洞、泥岩及砂岩隧道的快速掘进。所述的掘进掌子面为倾斜的结构，掘进掌子面的顶部向掘进方向倾斜。通过采用先在掌子面边缘挖槽，然后开挖掌子面其余部分的方案，能够实现分台阶预留核心土开挖方法，提高了施工效率。
