AI Technical Summary
Existing TBM dismantling technology requires the deployment of large hoisting equipment inside the dismantling tunnel, resulting in high construction difficulty, long construction period, and high cost. In particular, it is inefficient when two TBMs are connected under terrain constraints, and transportation and installation are difficult.
An auxiliary TBM dismantling device is adopted, which includes a bearing device at the bottom of the tunnel, a jacking and hoisting mechanism, and a tilting device. The TBM parts can be dismantled without disassembly through the jacking and tilting mechanism, and the dismantling is carried out using components such as arc-shaped ground beams, anchor bolts, jacking devices, and tilting fixtures.
It enables the rapid and convenient dismantling of the TBM without the need to remove the opening, shortening the construction cycle, reducing costs, improving efficiency, and minimizing the impact on subsequent construction.
