Description
Technical field
The invention belongs to tunnels and underground engineering guarded drainage technical field, relate to a kind of tunnel siphon drainge system and
Method of construction.
Background technology
The principle of " prevent, arrange, cut, block up, treatment in accordance with local conditions, comprehensive control " is followed in tunnel water handling design, existing
Waterproof/drainage structure geotechnique's non-woven fabrics is predominantly set between gunite concrete just supporting and form concrete two lining
And the flexible waterproof layer of splash guard, wherein, splash guard also serves as sealing coat.In actual use, this structure is prevented
There is certain defect in water plate sealing coat, such as, in the tunnel of IV, V, VI grade of country rock, and pushing away over time
Moving, the molecule in country rock accumulates over a long period, and makes geotechnique's non-woven fabrics produce and hardens phenomenon and cannot play a role in filtering,
So that the water that tunnel-liner is behind cannot smoothly flow therein in drain pipe.Investigation finds, major part tunnel-liner infiltration
It is the drain pipe not water outlet owing to arranging in lining cutting, it is impossible in meeting dewatering needs, and pipe, produce Sediment Siltation, lining
Building water behind to increase lining cutting generation corrosiveness or the tunnel-liner accumulation water yield behind, hydraulic pressure increases, and causes at lining
Build the infiltration of quality weakness or cracking.
Application publication number is that the Chinese invention patent of CN 102635402A discloses a kind of Tunnel wall infiltration disposal
The boring siphon drainage method that has a down dip, the method particularly as follows: have a down dip boring in the probing formation of Tunnel wall seepage point, brill
At the bottom of the aperture in hole and hole, relative relief is less than 8m；Standpipe at the bottom of the insertion hole, one end of siphon drainage pipe, storing up at the bottom of hole
Water pipe inserts foot of hole together with siphon drainage pipe；The other end of siphon drainage pipe inserts in the aqua storage tank of mozzle；
The subsoil water that country rock infiltrates enters the boring that has a down dip and causes water level in borehole to rise, and siphonic process occurs, and siphon drainage pipe will
Subsoil water in boring is discharged in mozzle in real time, and mozzle is again outflow tunnel in the gutter in water importing tunnel
Road.In the technical scheme of above-mentioned patent disclosure, by the way of dredging rather than be stifled, administer seepage, it is to avoid subsoil water oozes
The diffusion of leakage scope, will not produce lining cutting impervious barrier and destroy and produce bad consequence.Compared with above-mentioned patent, this
Invention improvement and technique effect as follows: 1) patent CN 102635402A do not explicitly point out construction siphonal
Bore angle and construction location, bring inconvenience in practice of construction, and uses bore angle 45-75 ° in the present invention,
Vertically drawing, set-up mode is simple；2) siphon material and parameter is set in patent CN 102635402A
Indefinite, and in the present invention, siphon uses PU pipe, boring to set a length of 1.8m, seeps water away from Tunnel wall
The cross section, tunnel of point, at the abutment wall of above 1.2m height at the bottom of hole, processes percolating water mode more convenient easy, and
PU pipe cost is the most economical, saves percolating water cost of disposal；3) in patent CN 102635402A, outlet makes
With water leg so that catchmenting of siphonage discharge is difficult to flow out along gutter, may affect continuing of siphonage
Carry out, be easily generated siphonage and lost efficacy, and the present invention places Plastic Drum in using siphon water outlet gutter,
Separately on Plastic Drum, at 0.1-0.2m, offer osculum so that siphonic process draining can be flowed out in time, also because going out
When mouth of a river water shortage siphonage vacuum is difficult to maintain, can suitably moisturizing in time, it is ensured that entering smoothly of siphonage
OK, work simply, easily operate；4) in patent CN 102635402A, bore mode is indefinite, and the present invention uses
Gas leg type hands air drill, the easy operation of construction party；5) in patent CN 102635402A, siphon water exit end is too short,
Separately connecing mozzle, both junctions easily leak gas leak phenomenon, are unfavorable for persistently carrying out of siphonage, and this
In invention, siphon directly leads out in outlet Plastic Drum, it is to avoid because siphon leaks, gas leakage affects siphon
The persistence of effect so that treatment technology for tunnel seepage water treatment efficiency is more significantly；6) siphon of the present invention uses polychlorostyrene second
Alkene pipe overcoat PU manages, and durability is good, beneficially the carrying out for a long time of siphonage, has saved siphon simultaneously
Material replacement cost, it is ensured that siphonal service life.
Summary of the invention
