Description
Technical field
The present invention relates to technical field of tunnel construction, more particularly to a kind of double main holes of three hole vcehicular tunnels and middle drift TBM-
Bore quick-fried combined construction method.
Background technology
Existing two hole vcehicular tunnel, when being constructed using central drift method, is considered, middle drift design area for cost of investment
It is often smaller, so cause that middle drift material channel is narrow, material organizational stress is big, delayed construction speed.And due to general
The escape and rescue scarce capacity of logical two hole tunnels, once there is accident, is highly detrimental to escape and rescue.
Three hole vcehicular tunnels are excavated according to traditional drilling and blasting method, and construction speed is slow, completion time of project length, work efficiency
It is low, in tunnel piercing construction location apart from hole remotely, construction exist very big safety risks.Tunnel boring machine method is to excavate
A kind of method in tunnel, tunnel and other underground spaces.Abbreviation TBM (tunnel boring manchine) method, it utilizes spy
The Large Cutting equipment of system, then rock shearing attrition crushing is transported rubble by supporting transporting equipment.TBM methods exist
Speed of application under normal circumstances is significantly faster than drilling and blasting method, and not only construction quality is good, and mechanization degree is high, easy for construction, has
Beneficial to environmental protection and save labour., should be not as flexible as drilling and blasting method but TBM methods are poor to the adaptability of unfavorable geological condition
It is relatively weak to the ability of complex geological condition especially soft rock environment., should therefore, it is necessary to a set of scientific and reasonable construction method
Construction method has the advantages of drilling and blasting method and TBM methods concurrently, to ensure quickly and safely to excavate three hole vcehicular tunnels.
The content of the invention
