Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drilling and grouting equipment, in particular to a drill arm switching device in a double-arm drill rig. Background Art

[0002] During the tunnel construction process, the ground is usually reinforced by bolt grouting when the formation is weak, and drilling operations are required during the construction. Especially in the shield construction in soft soil areas, in order to enhance the bearing capacity of the formation, formation grouting reinforcement is carried out synchronously during the segment assembly process. In order to meet the high-efficiency construction of shield tunneling, a drilling and grouting integrated device system needs to be designed to complete the drilling and grouting construction when the segments are assembled at the shield tail. The drilling and grouting integrated device system includes a modular bolt drilling device. The modular bolt drilling device realizes the drilling operation through the drill arm unit, so a drill arm switching device is needed to switch between the bolt drill rig and the steel flower pipe drill rig (of the double-arm drill rig).
