Description
Technical field
The utility model is related to TBM driving arrangements under the conditions of a kind of extruding large deformation.Suitable for water conservancy and hydropower, hand over
The underground engineering fields such as logical, municipal administration, water delivery gas transmission.
Background technology
The country has achieved considerable progress, has been widely used in the works such as railway, water conservancy, water power in terms of TBM constructions at present
Cheng Zhong.Because TBM carries out extensive guide and monitoring using monitoring, remote control and electronic information technology etc. to work progress extensively, make
Tunneling process is in optimum state all the time, relative to drilling and blasting method have the advantages that efficiently, quickly, high-quality and safe.Normal condition
The lower far super drilling and blasting method of speed of application, construction quality is good；In addition TBM mechanization degrees are high, easy construction, be conducive to environmental protection and
Labour is saved, mitigates labor strength, is easy to construction management.
But TBM is poor to the adaptability of unfavorable geological condition, reply complex geological condition is especially not as drilling and blasting method flexibly
Be soft rock environment ability it is relatively weak.
These unfavorable geological conditions are not only possible to cause the reduction of TBM excavation operations time availability, it could even be possible to occurring
TBM damages and is difficult to situation about passing through.The supporting of TBM During Initial Stage Constructions is comprehensive in time not as drilling and blasting method, rock before preliminary bracing
Open-assembly time is different in size, the accident for easily occurring danger stone injury device, and does not have drilling and blasting method machine in terms of preliminary bracing is carried out
It is dynamic flexible.TBM constructions take advance support measure flexible, timely not as drilling and blasting method tunneling construction, and advance support measure is not also complete
Into or advance support measure bearing capacity have not yet been formed, TBM advance developments.Above-mentioned unfavorable factor is in unfavorable geological condition
Consideration well must be given during lower construction.
The content of the invention
The technical problems to be solved in the utility model is：For above-mentioned problem, there is provided a kind of simple in construction, construction
TBM driving arrangements, are that TBM is smoothly dug to improve TBM drivage efficiencies under the conditions of convenient, lower-cost extruding large deformation
Enter to create conditions.
The technical scheme that the utility model is used is：TBM driving arrangements under the conditions of one kind extruding large deformation, it is special
Levy and be：It is disposed with extruding parallel and advance development with TBM driving tunnels and becomes TBM drivings tunnel both sides is spaced apart
Shape bears hole；Well cementing region is set in front of the TBM drivings tunnel, hole is born in the well cementing region by crimp
Wall rock drill-hole, which is in the milk, in front of to TBM driving tunnels to form.
The TBM driving tunnels bear the TBM drivings tunnel footpath that the distance between hole is 3 times with crimp.
The hole footpath that hole is born in the crimp is 3m.
The crimp bears hole and excavates to be formed using drilling and blasting method.
The beneficial effects of the utility model are：The utility model overcomes the limitation of TBM equipment of itself, utilizes external condition
Most country rock crimp is discharged, reduces the crimp that TBM tunnels are born in itself, and country rock in front of TBM can be entered
Row advance support.Supporting expense can be greatly lowered in the utility model, improve TBM drivage efficiencies.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
Fig. 2 is Fig. 1 top view.
Embodiment
Under soft rock environment, due to tunnel excavation, easily cause tunnel to extrude large deformation, influence is produced on TBM driving.
But TBM is due to the limitation of equipment of itself condition, it is impossible to implement advance support, the supporting measure and support apparatus used does not have yet
Flexibly, simple be difficult to successfully manage this extruding large deformation by TBM itself ability to drilling and blasting method, it is necessary to considers external means.
As shown in Figure 1 and Figure 2, the present embodiment is TBM driving arrangements under the conditions of a kind of extruding large deformation, in TBM drivings
The both sides of tunnel 1 are spaced apart to be respectively disposed with crimp parallel and advance development with TBM driving tunnels 1 and bears hole 2,
Hole, which is born, using the crimp discharges most crimp.Crimp bears hole 2 and TBM and tunnels tunnel 1 in this example
Between spacing be about 3 times of TBM drivings tunnel 1 hole footpath, on the one hand avoid crimp from bearing hole 2 and excavate to tunnel TBM
Tunnel 1 produces influence, on the other hand can also reduce the workload of TBM advance supports.
The hole footpath about 3m in hole 2 is born in crimp, is easy to construct and is reduced investment, is excavated using drilling and blasting method, is used
Random supporting, it is ensured that the construction time of cavern is stable, the later stage can optionally be blocked.
The characteristics of the present embodiment bears hole advance development using crimp, is bored to the TBM driving front country rocks of tunnel 1
Hole is in the milk, and the integrality of country rock in front of well cementing region 3, increase TBM driving tunnels is formed in the front of TBM drivings tunnel 1, is subtracted
Small TBM driving difficulty, it is ensured that TBM Advance rate.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the range of the utility model, change, addition or the replacement made should all belong to this reality
With new protection domain.
