Road element crane used for shield tunneling machine synchronous box culvert construction

Abstract

The invention relates to a road element crane used for shield tunneling machine synchronous box culvert construction. The road element crane comprises a crane traveling beam, traveling trolleys, lifting devices, a positioning support and a box culvert bracket. The two sets of traveling trolleys are arranged on the crane traveling beam and connected through the positioning support. The box culvert bracket is connected with the traveling trolleys through the lifting devices and is of a U-shaped structure. By adoption of the structure, box culverts can be mounted while a shield tunneling machine performs tunneling, and accessories of the box culverts are easy to mount; and meanwhile, mounting of the accessories is not limited to the mounting speed of the box culverts any more, the construction period of the whole project is greatly shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shield machine construction, in particular to a box culvert crane used for shield machine synchronous box culvert construction. Background technique [0002] With the development of transportation, more and more attention is paid to tunnel engineering. The construction period of tunnels is about 1-2 years or even longer. The earlier the tunnel is completed, the earlier the tunnel will be able to play its role and generate economic benefits. In tunnel section design, especially for larger diameter tunnels, box culverts are often designed below the tunnel section as installation space for drainage, power, communication and other pipelines. Under normal circumstances, the installation of the box culvert will be carried out after the tunnel excavation is completed. In this construction method, due to the transportation of segments and auxiliary materials during the excavation process of the shield machine, it...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the installation of the box culvert will be carried out after the tunnel excavation is completed. In this construction method, due to the transportation of segments and auxiliary materials during the excavation process of the shield machine, it is necessary to wait for the completion of the tunnel excavation before the box culvert can be installed. Installation, and during installation, the box culvert needs to be installed before installing the box culvert accessories. The whole process is time-consuming and laborious, and the longer the tunnel, the longer the material transportation distance and other reasons, the later construction efficiency is getting lower and lower.
