Abstract

The invention discloses an ultra-large-section special-shaped segment assembly machine. The ultra-large-section special-shaped segment assembly machine comprises a special-shaped track with the innercircumferential side being provided with an upper-layer rail surface and a lower-layer rail surface, and a first assembly mechanism and a second assembly mechanism used for assembling segments on theupper layer and the lower layer are arranged on the upper-layer rail surface and the lower-layer rail surface correspondingly. The first assembly mechanism and the second assembly mechanism of the ultra-large-section special-shaped segment assembly machine simultaneously travel along the special-shaped track, assembly of the segments on the upper layer and the lower layer is completed, interference is avoided, and the assembly effect of the segments is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a super-large-section special-shaped segment assembly machine. Background technique [0002] With the continuous advancement of my country's urban three-dimensional transportation, civil air defense projects and other infrastructure construction, the shape of the tunnel section presents a variety of requirements, such as underground parking lots, subways, highways and railways and other construction fields will have a large number of non-circular sections, that is, special-shaped tunnel section space development needs. [0003] Compared with circular tunnels, special-shaped tunnels can increase the effective use area by more than 25%, which not only greatly reduces the amount of land used and underground excavation area, but also reduces the overall cost of the project. The construction of special-shaped tunnels is relatively difficult, segment division and segment as...
