Abstract

The invention discloses a disassembling and assembling method for a shield tunneling machine in a tunnel. The disassembling and assembling method comprises the following steps: firstly, preparation work before the disassembling and assembling as well as the entering of the site, providing a supporting mechanism, wherein the length of the supporting mechanism is at least greater than the height between a bridge of the shield tunneling machine and the ground; secondly, disassembling, assembling and entering the site: transferring the supporting mechanism to the lower part of a bridge frame of the shield tunneling machine, and welding the supporting mechanism with the bridge frame of the shield tunneling machine to form the support for the bridge frame of the shield tunneling machine; thirdly, disassembling the shield tunneling mechanism: disassembling the shield tunneling mechanism, maintaining and overhauling various systems of the shield tunneling machine, and removing faults; fourthly, assembling the shield tunneling machine: reassembling the maintained shield tunneling machine, disassembling and transferring the supporting mechanism out of the tunnel. According to the disassembling and assembling method for the shield tunneling machine in the tunnel, the drilling of a vertical shaft in the ground is avoided, and the shield tunneling machine is hoisted out of the tunnel for maintenance; most of faults of the shield tunneling machine can be handled in the tunnel, huge construction is omitted, the construction time is greatly shortened, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a method for disassembling and assembling a shield machine, in particular to a method for disassembling and assembling a shield machine in a tunnel. Background technique [0002] The shield machine is a special engineering machine for tunnel construction, widely used in various tunnel projects such as subway tunnels, railway tunnels, water diversion tunnels, highway tunnels, mine roadways, and urban municipal tunnels. Due to the advantages of safety and reliability, high degree of mechanization, less earthwork, fast progress, and low construction cost, shield tunneling method construction can only rely on shield tunneling machines, especially when the geology is complex, the groundwater level is high and the tunnel depth is large. It is widely used in tunnel construction. [0003] Due to the complex construction conditions, narrow space and poor conditions of the shield machine, if the shield machine breaks down during the con...
