Description
Technical field
The present invention relates to tunnel drainage technical field, and in particular to a kind of pressure surface shape of tunnel rich water country rock, which is dropped down in adfluxion, to be drawn
Drainage mechanism.
Background technology
After rich water tunnel is excavated, the original seepage field of underground water is destroyed, tunnel turns into the new drain passage of underground water, from
And easily there is infiltration, water burst in tunnel tunnel face.Currently, tunnel water damage remains one of domestic outer tunnel Common Diseases, water
Harmful regulation is the technical barrier that domestic and international project interface is faced.Tunnel water damage harm is very big, no matter constructing or runing
It is open to traffic, all influences larger.In construction, rich water country rock has pressure surface planar trickling water to deteriorate tunnel construction environment, greatly hinders
Effective progress of preliminary bracing working procedure, while diluting gunite concrete, greatly reduces the intensity of preliminary bracing, very
To the formation seepage flow of supporting weak floor in the early stage breach, and then influence Second Lining Construction；Meanwhile, after tunnel operation is open to traffic,
Rich water country rock has pressure surface shape to drop down flowing water long-term aggregated, can reduce tunnel service life and tunnel in service life of equipment, deteriorate
Tunnel environment, influences traffic safety, adds operation maintenance cost；When running into severe wall rock geology condition, the effect of water
Surface collapse is easily caused, tunnel safety is influenceed.
In the extremely incident tunnel of these water damages, particularly high altitudes and cold highlight lines surrounding rock tunnel, country rock planar is dropped down
The relatively general weather of flowing water disease is more serious with wall rock condition, significantly impacts constructing tunnel and carries out in order and later stage operation peace
Entirely.In frigid plateau region country rock planar assemble water after thawing is circulated, at the beginning of tunnel branch, two lining concrete strengths cause compared with
Big influence, or even Local Cracking, can carry out great hidden danger to structure safety belt.
Currently the administering method on such disease, mostly adds insulation material, to prevent tunnel from enclosing in supporting in the early stage
The frost heave action produced in rock by water damage；Occur a large amount of planars when preliminary bracing and drop down flowing water disease, or ejectment of punchinging, or oozing
Splash guard, progress of the reduction water damage to preliminary bracing gunite concrete are fixed in water country rock face.But all there is construction effect in these methods
Rate is low, and cost is high, and can not effectively prevent influence of the water damage to later stage operation tunnel.How both efficiently to prevent water damage to construction
Influence, while can block influence of the water damage to later stage operation tunnel at the root of water damage again, the problem of be individual urgent need to resolve.
The content of the invention
To solve above technical problem, the present invention provides a kind of pressure surface shape of tunnel rich water country rock and drops down ejectment water dispenser in adfluxion
Structure.
Technical scheme is as follows：
A kind of pressure surface shape of tunnel rich water country rock, which drops down, draws drainage mechanism in adfluxion, its key is：, should including tunnel surrounding
The pressure surface shape of tunnel surrounding inwall drops down to be sticked to have along the short transverse in tunnel at stream to be opened at least one aqueduct, the aqueduct
Provided with priming hole, the pressure surface shape drop down stream place tunnel surrounding on covered with waterproof roll, the aqueduct is located at described
Between waterproof roll and the tunnel surrounding, the lower end of the aqueduct, which is connected with, drops down water collecting mechanism.Using above-mentioned technical side
Case, which is collected tunnel surrounding pressure surface shape using waterproof roll and dropped down at stream, drops down water, prevents from dropping down first branch and two lining concretes that water penetrates into tunnel
Interior, the water that drops down collected is entered in aqueduct by priming hole and is discharged into and drops down in water collecting mechanism, and collection drops down water and can concentrate discharge
Tunnel, this set effectively increases the effect of tunnel scar water harnessing, and simple in construction, and strong operability, cost is relatively low, waterproof
Evil effect is lasting, while can prevent tunnel in cold area water damage from producing freeze-thaw damages to branch, two lining concretes at the beginning of tunnel.
As preferred：The above-mentioned water collecting mechanism that drops down includes longitudinal drainage french drain, circle draining french drain and centre drain, institute
State length direction of the longitudinal drainage french drain along tunnel to set, width of the circle draining french drain along tunnel is set, described
Centre drain is located at the bottom in tunnel, and the lower end of the aqueduct is introduced in the longitudinal drainage french drain, the circle draining
One end of french drain is connected with the longitudinal drainage french drain, and the other end is connected with the centre drain.Using program aqueduct
Interior dropping down after water all flows into longitudinal drainage french drain enters dropping down in centre drain, centre drain through circle draining french drain again
Water can concentrate discharge tunnel by water pump.
Above-mentioned waterproof roll and aqueduct are clenched on the tunnel surrounding by rivet respectively.Using the design waterproof
Coiled material and aqueduct fix simple, solid and reliable, workable
Above-mentioned aqueduct is Permeable blind pipe, and the Inter-fiber voids of the Permeable blind pipe form the priming hole.Set using this
The spacing gap using Permeable blind pipe is counted permeable and water will be dropped down be fully incorporated in longitudinal drainage french drain, without starting diversion in addition
Hole.
Each pressure surface shape, which is dropped down at stream, is at least equipped with two Permeable blind pipes, is spaced between the adjacent Permeable blind pipe
1 meter.Ensure that the water that drops down that pressure surface shape is dropped down at stream is all effectively introduced in longitudinal drainage french drain using this design, prevent overflow from oozing
Leakage.
Beneficial effect：Using the beneficial effects of the invention are as follows collect tunnel surrounding pressure surface shape with waterproof roll to drop down dropping down at stream
Water, prevents from dropping down water and penetrates into the first branch and two lining concretes in tunnel, and the water that drops down collected is entered in aqueduct and is discharged into by priming hole and drops down
In water collecting mechanism, collection drops down water and can concentrate discharge tunnel, and this set effectively increases the effect of tunnel scar water harnessing,
And it is simple in construction, strong operability, cost is relatively low, and anti-water damage effect is lasting, while tunnel in cold area water damage can be prevented at the beginning of tunnel
Branch, two lining concretes produce freeze-thaw damage.
Brief description of the drawings
