Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation, in particular to a wheel-mounted mobile platform for supporting small-section tunnel excavation. Background Art

[0002] A hydraulic tunnel refers to a water tunnel dug in a mountain or underground. A hydraulic tunnel can be used for irrigation, power generation, water supply, water discharge, water transfer, construction diversion and navigation. In the construction process of small-section tunnels, traditional gantry is usually used as the working platform, and the loader is used to lift and move the traditional gantry. During the construction process, it was found that the traditional gantry has a fixed structure. Although the loader can move the position in the tunnel, the overall height of the gantry cannot be adjusted, and it is difficult to take into account the construction at different heights in the tunnel, which makes the operation inconvenient. In addition, the traditional gantry is generally welded by I-beams, steel bars, steel plates and other steel materials. The structure is relatively simple, and the stability and safety are poor during construction. Utility Model Content
