Description
Technical field
The invention belongs to tunneling and underground engineering technical fields；Particularly relate to a kind of shield jacking New Austrian Tunneling Method supporting
Counterforce device and its setting method.
Background technology
At present tunnel is carried out in no underground water or the soft rock of few underground water, such as IV, V grade of country rock or soil property and rocky stratum
Road boring construction is generally constructed using New Austrian Tunneling Method or shield method；Wherein shield method is that one kind of tunneling and underground engineering is complete
Mechanized construction method, it is to promote Shield-type machinery in the earth formation, and supporting surrounding country rock by shield shell and section of jurisdiction prevents
Caving in tunnel occurs, while soil excavation is carried out with cutting apparatus in front of excavation face, machinery transports hole by being unearthed
Outside, it pressurizes in the lining cutting of the assembled cyclization in rear portion jacking by jack, then assembled precast concrete section of jurisdiction, forms tunnel structure
A kind of mechanized construction method；Shield method can realize the continuous driving in the construction of stratum, and construction efficiency is high, but liner structure
Using prefabricated pipe section assembled structure, cost is higher.
The construction of underground New Austrian Tunneling Method be using safeguard and using tunnel surrounding self-bearing ability as basic point, it is mixed using anchor pole and injection
Solidifying soil is main supporting means, timely carries out supporting, controls the deformation and relaxation of country rock, and country rock is made to become supporting and protecting system of tunnel
Component part, and the side for constructing tunnel and underground engineering design being instructed to construct by measurement to country rock and supporting, monitoring
Method and principle；Use New Austrian Tunneling Method construction tunnel section that circle, rectangle etc. can also be used based on the shape of a hoof, lining cutting mode is general
It is using composite lining form, i.e., highly beneficial to lining cutting stress in a manner that preliminary bracing adds secondary lining to be combined；Country rock
Under the conditions of the larger preliminary bracing of flexibility, larger deformation can be generated, releases most deformation energy, thus is set after making
Secondary lining reduce stress, after secondary lining applies, but can to preliminary bracing generate radial-thrust force, so as to improve initial stage branch
The stress condition of shield；And lining cutting any surface finish is smooth, is conducive to tunnel ventilation and waterproof, protects outer layer supporting；But on ground
When in lower IV, V grade of country rock of soft rock using New Austrian Tunneling Method construction, it need to generally divide bench excavation, mechanization degree is low, and operation is with artificial
Based on, construction efficiency is relatively low, and security risk is high, and tunneling operation environment is poor.
