Abstract

The invention relates to the technical field of civil engineering, in particular to a movable-type hydraulic work protective platform applied into a tunnel. The movable-type hydraulic work protectiveplatform comprises a flat transporting trolley, a wheeltrack-type hydraulic lifting rack part mounted on a trolley body, a wheeltrack-type hydraulic lifting arching mounting trolley part and a wheeltrack-type hydraulic lifting telescopic protective rack part. The wheeltrack-type hydraulic lifting rack part comprises a wheeltrack-type hydraulic lifting rack which comprises a rack upper part and a rack lower part. The rack lower part is provided with a rack travelling device and supporting legs for supporting the hydraulic lifting rack, and the rack upper part is provided with a lifting device and a foldable working platform. The wheeltrack-type hydraulic lifting arching mounting trolley part comprises a mounting trolley mounted on the trolley working platform. The wheeltrack-type hydrauliclifting telescopic protective rack part comprises a wheeltrack-type hydraulic lifting telescopic protective rack, a protective rack lifting device and a protective rack lifting platform. The movable-type hydraulic work protective platform has the technical advantage that the safety degree of centralized operation is high.

Description

technical field

[0001] The invention relates to the technical field of civil construction engineering, in particular to a mobile hydraulic work protection platform used in tunnels. Background technique

[0002] With the continuous rapid development of my country's economy, the focus of the construction of high-speed railways and expressways is gradually tilted to the west, and the terrain and landforms of the mountains and valleys in the west make the proportion of tunnel construction more and more high, and some even exceed 80%. , especially long tunnels, high ground stress tunnels, soft rock tunnels and other unfavorable geological tunnels have many types, rapid changes, and difficult construction tasks. Tunnel engineering is often the control point of engineering construction projects. Layers, alteration zones, landslides, high ground stress, rockbursts, etc., are prone to landslides, falling blocks, surface subsidence, deformation, collapse, etc. The progress of the projec...
