Title:
COMMUNICATION TUNNEL BORING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/056959
Kind Code:
A1
Abstract:
A communication tunnel boring machine comprises a pipe section crane trolley (3). A pipe section conveying device (1) is provided on one side of the pipe section crane trolley. A rear supporting system is provided on the other side of the pipe section crane trolley. The pipe section crane trolley is supported on and spans a counterforce support system. A pipe section pushing system is provided on the counterforce support system. The pipe section pushing system pushes a pipe section (2), and the pipe section acts on a main boring machine (4). An extensible conveying device (13) is provided between the pipe section pushing system and the main boring machine. The boring machine distributes force on a counterforce frame of the counterforce support system to a main tunnel pipe piece by means of a bridge plate, such that sufficient counterforce support is provided during tunnel boring. Muck is discharged continuously, thereby avoiding the case in which boring needs to be stopped when the muck is being discharged from a muck container, and achieving automated mechanical boring.
