Abstract
The utility model is related to a kind of stifled row's integrated structure of rich water karst tunnel.The purpose of this utility model is to provide a kind of simple in construction, easy construction, the stifled row's integrated structure of lower-cost rich water karst tunnel, to strengthen the quantitative excretion of liner structure and realization to karst water.The technical solution of the utility model is:A kind of stifled row's integrated structure of rich water karst tunnel, it is characterised in that:In the original liner structure of tunnel and karst intersection arrangement stiffener concrete lining structure;The karst bottom, remote tunnel side are disposed with scupper, graded broken stone filter layer and concrete block wall are sequentially provided between karst and scupper, concrete block wall is provided with some drainpipes that graded broken stone filter layer and scupper are connected through concrete block wall.The utility model is applied to hydraulic tunnel, traffic tunnel, water delivery gas pipeline, underground pipe gallery that karst area is built etc..
Description
Technical field
The utility model is related to a kind of stifled row's integrated structure of rich water karst tunnel.The water built suitable for karst area
Work tunnel, traffic tunnel, water delivery gas pipeline, underground pipe gallery etc..
Background technology
Karst is one of common geological disaster in the underground engineering constructions such as railway, highway, water conservancy and hydropower, mine working.
The landform that 15% is there are about on the earth is karst features, and many countries are annual all because of different degrees of tunnel karst disaster in the world
Cause huge economic loss.China is vast in territory, and it is mountain area to have 70%, and geographical geological conditions is sufficiently complex, is rock in the world
Molten distribution most wide country, it is western built and positioned at karst area occupy sizeable proportion in tunnel is built, in these tunnels
In, because the presence of karst unfavorable geology disaster to the construction and operation of tunnel causes serious threat.Positioned at tunnel top plate,
Bottom plate and the solution cavity of side caving in suddenly in construction or chip off-falling cause the heavy damage of Wall Rock of Tunnel and supporting construction, and
Trigger a large amount of landslides, have a strong impact on the normal construction of tunnel.The Geological Hazards such as large-scale water burst, prominent mud, into
One of middle most serious, most common geological disaster are built for China's karst area tunnel, large-scale gushing water, prominent mud not only jeopardize
Tunnel construction safety, influences construction speed, once improper measures, tunnel can often built up, and rear operating environment is severe, and earth's surface is ecological
Deteriorate, the production and life given people causes heavy losses.
Tunnel occur water burst dash forward mud when, the conventional more principle use based on " row ", drainage sunk well mainly passes through secretly
Ditch, pipeline, culvert, drain cavern etc. dam exclusion underground water.But this processing method based on " row " generate it is many tight
The geological disaster of weight and environmental problem, such as surface subsidence, surface subsidence deformation, dry pool wellspring, farmland water shortage, forest are withered
Deng, had a strong impact on around the ecological balance.Meanwhile, this regulation principle, cause the operation of the tunnel after lining cutting there is also
Very big future trouble.
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
The stifled row's integrated structure of convenient, lower-cost rich water karst tunnel, to strengthen liner structure and realize quantitative row to karst water
Let out.
The technical scheme that the utility model is used is:A kind of stifled row's integrated structure of rich water karst tunnel, it is characterised in that:
In the original liner structure of tunnel and karst intersection arrangement stiffener concrete lining structure;
The karst bottom, remote tunnel side are disposed with scupper, are sequentially provided between karst and scupper
Graded broken stone filter layer and concrete block wall, concrete block wall pass through concrete block wall connection level with broken provided with some
The drainpipe of stone filter layer and scupper.
The depth that the drainpipe enters graded broken stone filter layer is more than 1m.
The thickness of the graded broken stone filter layer is 1.5~2m.
The thickness of the concrete block wall is 1.5~2m.
The scupper size is 3m.
The stiffener concrete lining structural thickness is more than or equal to 50cm.
The beneficial effects of the utility model are:The utility model realizes the reinforcement to structure and the quantitative row to underground water
Put, be effectively reduced the water pressure acted on liner structure, it is ensured that structure safety, and the silt that karst is gushed out is entered
Processing is gone, it is ensured that the permanently effective operation of drainage effect and scupper.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
As shown in figure 1, the present embodiment is a kind of stifled row's integrated structure of rich water karst tunnel, feelings are disclosed according to karst
Condition, in the original liner structure 2 of tunnel and the intersection of karst 4 arrangement stiffener concrete lining structure 3, the structural thickness
It is difficult to be less than 50cm, and carries out arrangement of reinforcement, is dashed forward water burst and prominent mud with resisting karst 4, it is ensured that the safety of original liner structure.
Scupper 8 is arranged in the bottom of karst 4, away from the side of tunnel 1, scupper size requires about 3m, to ensure hole
It is interior that there is enough spaces to be constructed.In karst 4 and the intersection of scupper 8, the He of graded broken stone filter layer 5 is sequentially arranged
Concrete block wall 6, concrete block wall 6 is provided with some through the connection graded broken stone of concrete block wall 6 filter layer 5 and row
The drainpipe 7 in water hole 8.
The thickness of graded broken stone filter layer 5 is general in 1.5~2m in the present embodiment, and main function is reply karst 4
The blocking that block stone, silt for inside gushing out etc. may be caused to scupper 8 and drainpipe 7, it is ensured that drainage effect, and one can be played
Fixed cushioning effect.
The thickness of concrete block wall 6 is general in 1.5~2m in this example, and main function is resistant to the high pressure of karst 4
Prominent water burst, to ensure the plugging effect to karst 4.
Drainpipe 7 need to enter the certain depth of graded broken stone filter layer 5 (being more than 1m) in the present embodiment, it is ensured that in filter layer
Water can be discharged in time, reduce the water pressure acted on stiffener concrete lining structure 3 and concrete block wall 6.
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.
