Abstract

The invention discloses a full-section rock ripper for a long-distance heavy-gradient inclined shaft. The full-section rock ripper comprises a shield body, a handpiece arranged on the front end of the shield body and composed of a cutterhead and a main driving system, a cutterhead capable of rotating in two directions to discharge slag, an excavation cabinet located behind the cutterhead, a sealable slag receiving hopper and an anti-surge door, which are arranged in the excavation cabinet, a stabilizer arranged at the top part in the shield body, a propelling oil cylinder arranged in the shield body and hinged with the handpiece, an explosion proof drainage system, an explosion proof ventilating and dedusting system and a mainframe belt conveyor, wherein the full-section rock ripper further comprises a duct piece assembling machine arranged at the back end of the shield body, an assorted back belt conveyor connected with the mainframe belt conveyor and a quick material pouring and conveying system. The full-section rock ripper disclosed by the invention can effectively solve such problems in the long-distance heavy-gradient inclined shaft as burst of massive water and harmful gases, tunneling speed and efficiency, auxiliary material transport, mainframe overturning and lateral rolling of mainframe.

Description

technical field [0001] The invention belongs to a full-section rock tunneling machine (TBM), in particular to a full-section rock tunneling machine for long-distance and large-slope inclined shafts. Background technique [0002] At present, the maximum slope of tunnels constructed by the tunnel boring machine method in foreign countries is 84% ​​upward and 58% downward. Unfavorable geological problems such as a large amount of water gushing. On the other hand, tunnels with large slopes (more than -10%) that are excavated downwards mainly use pressure-balanced shields, which can easily solve unfavorable geological problems such as large amounts of water gushing and large amounts of harmful gases, but the excavation speed is slow, the efficiency is low, and the scope of geological adaptation is narrow. [0003] The maximum slope of the tunnels constructed by the domestic tunneling machine method is only ±5.5%, and all of them adopt pressure-balanced shields, which have slow t...
