Document Type and Number:
WIPO Patent Application WO/2018/133743
Kind Code:
A1
Abstract:
Disclosed is an tunnelling apparatus for use in a pipe jacking method, the tunnelling apparatus comprising an excavating apparatus (1), a head front-end track (2), a central track (3) and a rear apparatus (4), wherein the excavating apparatus (1) is composed of a transmission apparatus (1-1) and a chain cutter (5), the transmission apparatus (1-1) being composed of a driving apparatus (1-1-1) and a sprocket (1-1-3); during construction, the chain cutter (5) for excavating rock and earth runs on the head front-end track (2) and the central track (3), and the shape of a head excavation face is the same as that of the cross section of a tube section (6); the rear apparatus (4) comprises a jacking apparatus (4-1), mounted in a construction well; the front end of the central track (3) is connected to the head front-end track (2), the tail end of the central track (3) is connected to the rear apparatus (4), and during construction, the driving apparatus (1-1-1) drives the chain cutter (5), so that the chain cutter (5) runs along the tracks; and a cutter on the head front-end track (2) excavates the ring-shaped rock and earth in a projection part of the cross section of the tube section (6).In a work well, an operating platform is constructed, and the impact on the surrounding environment is low. The head of a first tube section (6) is an excavating face of the excavating apparatus (1), excavated rock and earth are driven along with the chain cutter (5) into the work well, the tube section (6) is ejected into position and then the rock and earth are cleared in the tube section (6), construction is simple, quality is good, the construction period is short, and costs are low.
