Abstract

The invention discloses a cutting and supporting dual-purpose mechanical device and method for treating tunnel surrounding rock, and belongs to the technical field of tunnel and underground engineering auxiliary construction devices. The device is convenient to move by arranging a travelling mechanism, and by adjusting the lifting height and the tilt angle of a continuous pushing jack, a cutting and supporting system is close to the surrounding rock. A cutting mechanism and a hydraulic jacking mechanism are controlled correspondingly by a controller, two working modes of surrounding rock cutting and surrounding rock supporting are provided, the device is convenient to use, the time and labor are saved, the safety of operation is high, the entire device is small in size and can be suitablefor various tunnel environments, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of auxiliary construction equipment for tunnels and underground engineering, and relates to a cutting and supporting dual-purpose mechanical equipment and method for treating surrounding rocks of tunnels. Background technique [0002] During the construction of the tunnel, when the conditions of entering the surrounding rock are complex, especially when the soft horizontal stratum is encountered, it is usually prone to over-excavation of the vault. At the construction site, for surrounding rocks that have not completely lost their bearing capacity, construction workers usually adopt a simple wooden support method to support the loose surrounding rocks in order to protect the bearing capacity of the surrounding rocks. For surrounding rocks that have lost their bearing capacity and may fall at any time In order to ensure the safety of construction, construction workers usually use high-pressure water jetting t...
