Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, and more specifically, to a tunnel boring machine large-slope translation device. Background Technology

[0002] A tunnel boring machine (TBM) is an integrated tunnel construction equipment that uses a cutterhead to cut through soil layers and simultaneously complete processes such as excavated soil transportation and segment assembly to form a tunnel structure in one step. Its core advantages lie in construction efficiency, adaptability to geological formations, and environmental friendliness, making it widely used in subways, municipal utility tunnels, and other applications. TBM launching is one of the most dangerous processes in TBM construction. Improper handling during this process can lead to a series of serious consequences, such as water inrush at the tunnel portal, sand inrush, and ground subsidence, causing irreparable losses. The conditions above the launching shaft are complex, and the presence of existing structures such as municipal utility tunnels significantly increases the difficulty of TBM launching. Furthermore, some TBM launching points require a certain slope, further increasing the difficulty. Therefore, we have proposed a TBM steep-slope translation device. Utility Model Content
