Problems solved by technology

However, the above-mentioned technology is only suitable for the construction of inclined shafts with large slopes and high buried depths. It is difficult to switch between inclined shafts and flat tunnels. Two roadheaders are still needed to complete the excavation of inclined shafts and flat tunnels. The construction investment is large and the construction efficiency is low.

Abstract

The invention discloses a tunnel inclined shaft construction system and a construction method. The tunnel inclined shaft construction system involves a starting device, an inclined shaft TBM and a receiving device, wherein a follow-up transportation system is arranged inside an inclined shaft excavated by the inclined shaft TBM, the inclined shaft TBM comprises a tunneling main machine and a rearmatching part, and a safety anti-running device is arranged between the tunneling main machine and the rear matching part; and the tunneling main machine comprises a cutterhead, a main drive, a star-shaped beam and a muck discharging mechanism, the main drive is arranged on the star-shaped beam and connected with the cutterhead, a cutter conveying tool is arranged inside the star-shaped beam, andthe muck discharging mechanism corresponds to the cutterhead. The structural design of the tunnel inclined shaft construction system is suitable for large-gradient inclined shafts, and the construction method is simple and effective, improves efficient and safe starting of the inclined shaft TBM, is a great innovation of inclined shaft construction and has high popularization value.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel construction system and construction method for an inclined shaft. Background technique [0002] TBM hard rock tunnel boring machine is a special construction machine for tunnel boring. It has the functions of excavating and cutting soil, conveying mud and slag, and assembling tunnel lining. It has been widely used in tunnel projects such as subways, railways, highways, municipalities, and hydropower. . Conventional TBM roadheaders are suitable for the construction of flat tunnels with a slope of ±5%, and there is no case of TBM application in large-slope inclined shafts in China. In the pumped storage power station, the diversion inclined shaft and the upper level tunnel are usually connected. If the TBM construction method is used, the diversion inclined shaft needs an inclined shaft TBM, which is suitable for the construction of large-slope tunnels; the f...
