Abstract

The invention discloses a separated-type tunnel steel arch mounting device which comprises an excavation trolley, an anchor rod mesh elevator arranged on the part, close to the hole end, of the excavation trolley, an arch elevating mechanism, arch translation mechanisms arranged below side wings on the two sides of the top layer of the excavation trolley, arch top jacking mechanisms arranged on the two sides of a top layer platform of the excavation trolley and perpendicular to the top layer platform, and arch lateral jacking mechanisms arranged below the side wings on the two sides of the excavation trolley. The separated-type tunnel steel arch mounting device can be directly mounted on the top layer platform of the excavation trolley, the construction cost of the device is low, and through movement of an arch in the device in the front-back direction, left-right direction, up-down direction, oblique direction and the like, the arch is accurately in place.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment. Background technique [0002] With the development of national infrastructure, the infrastructure market is booming, and roads and railways are realizing leapfrog development, among which tunnel construction is an important part of road and railway construction. In the process of tunnel construction, there are often practical problems such as insufficient foundation bearing capacity in the process of new stress formation due to lack of solid foundation support, which leads to tunnel instability and collapse, which seriously affects the safety of people and equipment. hindered the progress of construction. In the actual construction process, in order to solve the above-mentioned practical problems such as tunnel instability and landslides, it is necessary to quickly and effectively support the excavation section during the tunnel excavation process. [0003] But at present, the actua...
