Problems solved by technology

Using this method to line the emergency avoidance belt requires disassembly, transportation, and assembly operations in the tunnel. Due to the narrow space in the tunnel and the limited space, and the repeated disassembly of the lining trolley, this method not only directly leads to the difficulty of guaranteeing the lining accuracy, Moreover, the on-site assembly is labor-intensive, the construction efficiency is low, and the construction period is long.

Abstract

A retractable emergency car avoidance belt tunnel lining trolley comprises a portal assembly, a formwork assembly and a bracket assembly. The portal assembly comprises a left portal assembly (1) and a right portal assembly (20) which are separated, the upper portion of the left portal assembly (1) is successively connected with a left bracket assembly (30) and a left formwork assembly (70), the upper portion of the right portal assembly (20) is successively connected with a right bracket assembly (40) and a right formwork assembly (70'), a detachable middle bracket assembly (50) is connected between the left bracket assembly (30) and the right bracket assembly (40), and a retractable connecting mechanism is disposed between an upper crossbeam (2) of the left portal assembly (1) and an upper crossbeam (21) of the right portal assembly (20). The trolley can be automatically and fast assembled into a lining formwork of an emergency car avoidance belt, so that lining speed of the emergency car avoidance belt is effectively increased, lining quality is guaranteed, and labor intensity is reduced.

Description

technical field [0001] The invention relates to a tunnel construction machine, in particular to a telescopic emergency vehicle avoidance belt tunnel lining trolley. Background technique [0002] In the construction of relatively long road tunnels, a plurality of emergency avoidance strips are usually lined. The known emergency avoidance strips of highway tunnels are mainly used to prevent accidents in the tunnel from hindering the entire traffic and avoiding casualties. Because the section of the emergency avoidance zone of the tunnel is several meters wider than the section of the main tunnel, the conventional emergency avoidance zone lining trolley cannot directly pass through the main tunnel to the next emergency avoidance zone tunnel. The general construction process is to disassemble part of the emergency avoidance belt trolley after pouring is completed, so that the trolley can easily pass through the main hole to reach the next emergency avoidance belt, and the remain...
