Abstract

The invention discloses a multifunctional combined crawler-type ascending and descending operation vehicle. The multifunctional combined crawler-type ascending and descending operation vehicle comprises a first ascending and descending work table, a second ascending and descending work table, a trolley and a walking mechanism, wherein the first ascending and descending work table and the second ascending and descending work table are respectively connected with the trolley, and can ascend and descend relative to the trolley; and the walking mechanism is connected with the trolley and is used for moving the trolley. By using the multifunctional combined crawler-type ascending and descending operation vehicle, construction personnel can flexibly drill in a working face.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a multifunctional combined crawler-type lifting operation vehicle. Background technique [0002] The pre-reinforcement of the full section of the tunnel regulates the ability of the surrounding rock to naturally form an "arch effect" and the deformation response of the tunnel by controlling the stiffness and deformation of the core body to be excavated, so as to achieve the overall stability of the tunnel during the construction stage. In the weak surrounding rock, the full-section pre-reinforcement technology makes full use of the "arch effect" of the surrounding rock through artificial "pre-reinforcement" measures, and further exerts the self-stabilizing ability of the surrounding rock, which also increases the strength of the surrounding rock equivalently. , so that mechanized full-section excavation and tunneling can be realized. [0003] The working process of tunnel full-s...
