Abstract
Karst method for treating water is related to karst method for treating water in tunnel in team road.Mainly solve the problems, such as that pipe laying ejectment is invented there are larger difficulty of construction in hole when current water yield is larger.It is applied in front of tunnel heading and bores advanced hole, advanced hole starting point is at prediction gushing water with preceding 5~10m；Range of grouting is the circle of radius 12m, and slip casting section point tricyclic is implemented；6m is stayed not excavate the only slurry disk as next slip casting section after the completion of one slip casting section；Injected hole arrangement is radial in umbrella shape towards direction is excavated by working, and drilling is arranged to a few, and is combined using long short-bore；Injecting paste material is cement slurry；Drilling and grouting sequence are from outer ring to inner ring since arch, and same collar aperture interval construction buries seamless steel pipe as orifice tube in only slurry disk before slip casting；Single hole grouting pressure reaches design final pressure and continues slip casting 10min or more, can terminate this hole slip casting.Advantage is that difficulty of construction is small, and effect is good.
Description
Technical field:
The present invention relates to karst method for treating water in tunnel.
Background technique:
Karst water is underground water of the preservation in the corrosion fissure and solution cavity of soluble rock stratum, most evident characteristic be distributed pole not
Uniformly, especially common in limestone area.The tunnel construction phase encounters the surprise attack of water burst, often floods construction site, destroys by rush of water
Equipment, causes equipment and personal injury, and schedule delays increase construction investment.The permanent runtime can also jeopardize the knot of diversion system
Structure safety.For the water burst, according to the conventional method, the mode of pipe laying ejectment in hole is mainly taken to be handled, due to karst
Actually move towards complex, there are biggish difficulty of construction and construction risk, handlings for pipe laying ejectment in hole when water yield is larger
With higher, effect not can guarantee.
Summary of the invention:
Technical problem to be solved by the invention is to provide a kind of processing karst water expense is low, difficulty of construction is small, the good team of effect
Karst method for treating water in road.
Above-mentioned purpose is achieved in that
Objective condition limitation cannot use drainaging scheme, or because solution cavity is larger and is filled-type, and when having abundant underground water,
Using grouting water blocking method；
Tunnel is discharged, total flow >=10m by fracture, rich water karst band when visiting at least 4 holes in the hole of 5~6, water hole3It is adopted when/h
With tunneling boring deep hole grouting water blockoff；
One, according to advance geologic prediction data, front of tunnel heading applies 5~6 advanced holes of brill, verifies underground water developmental state and molten
The geologic aspects such as hole, the orientation of solutional cavity, scale, advance borehole starting point should be at prediction gushing waters with preceding 5~10m；
Two, range of grouting is the circle of radius 12m, and slip casting segment length 30m, a point tricyclic implemented, the long 12m of the first ring, the long 10m of the second ring,
The long 8m of third ring；6m is stayed not excavate the only slurry disk as next slip casting section after the completion of one slip casting section；
Three, by working, towards direction is excavated, in umbrella shape, radial, opening diameter 115mm, drilling are arranged to a few to injected hole arrangement,
Internal and external cycle presses quincunx arrangement, and is combined using long short-bore, by reach slip casting sufficiently, do not stay dead angle for the purpose of, slurries diffusion
Radius 2m, bottom hole spacing are not more than 3m；
Four, injecting paste material is cement slurry (using cement-sodium silicate double liquid when necessary), and concentration of slurry is according to rock mass condition and water
Amount size is adjusted, and the ratio of mud of cement slurry is 0.5:1~1:1, and dual slurry matching parameter is C:S=1:0.6~1.0(volume
Than), modulus of water glass 2.6~2.8, concentration of sodium silicate 35B；
Five, grouting pressure value is 0.5~1.0MPa of first pressing, 3.0~5.0MPa of final pressure；
Six, when rock crusher, cranny development, using protrusive slip casting；Wall-rock crack is not enough developed, when rock stratum is slightly good, after
Formula slip casting is moved back, drilling and grouting sequence are from outer ring to inner ring since arch, and same collar aperture interval is constructed；
Seven, Φ 140mm seamless steel pipe is buried in only slurry disk before slip casting as orifice tube, aperture pipe range 3m, exposed 0.2~
0.3m；
Eight, slip casting ending standard: single hole grouting pressure reaches design final pressure and continues slip casting 10min or more, can terminate this hole note
Slurry；Single hole grouting amount with design grouting amount it is roughly the same, at the end of 20~30L/min or less of grout absorption can terminate this hole note
Slurry；
Nine, after the injected hole of a slip casting section has all been infused, bores 2~3 holes and slip casting effect is checked, and coring is observed
Slurries fill situation, while water yield should not exceed 0.2L/min.m in inspection hole, and the water leakage of certain is not more than 10L/
min；Or under 1.0MPa packer permeability test, inspection hole inflow is less than 2L/min.m, otherwise encrypts bored grouting.
Ten, slip casting start-up operation identity distance predicts 5~8m at gushing water, to guarantee that enough sealing batholites, terminal should be more than pre-
Survey gushing water section 5m.
The invention has the advantages that processing karst water expense is low, difficulty of construction is small, and effect is good, guarantees tunnel structure object and battalion
Transport the normal use and traffic safety of equipment.
