Abstract

The invention provides a tunneling machine by a new Austrian tunneling method, and aims at solving the problem of insufficient equipment in the prior art. New Austrian tunneling construction mechanized, integrated and factorized, the construction speed and construction environment are improved, the labor intensity of works is reduced, and the construction safety is improved. The tunneling machine comprises a main structure, a tunneling device, a retaining and protecting system, a deslagging system, a travelling system, a guiding system, a control system, a hydraulic system, a ventilation dust-collection system, an inverted arch casting system and an auxiliary construction system. The tunneling machine is brand-new new Austrian tunneling construction equipment, adopting mechanical tunneling, and organically combines tunneling, deslagging, retaining and supporting and inverted arch casting to realize mechanization of tunneling construction. The tunneling machine has the advantages of simple equipment design, high construction efficiency and good safety, and is applicable to construction of large soft rock tunnels.

Description

technical field [0001] The invention belongs to tunnel construction machinery, which is mainly used for excavation and construction of tunnels, in particular to a new Austrian method tunnel boring machine. Background technique [0002] At present, there are two main technologies for tunnel construction, one is tunnel boring machine technology, and the other is new Austrian method tunnel construction technology. At present, tunnel boring machine technology is mainly used for circular, hard rock, and long tunnel construction. The technology is mature and has been Basically meet the factory construction requirements, but the construction equipment for the new Austrian method tunnel construction technology mainly includes rock drilling rigs, wet spraying machines, steel arch installation machines, waterproof board laying machines and other machines, mainly using the drill and blast method Construction, there is still no set or a kind of mechanized and integrated large-scale cons...
