Description
Technical field
The present invention relates to tunnel lining structure, the hard rock tunnel grown particularly to a kind of subsoil water or karst area tunnel
Road lining structure.
Background technology
Enter 21st century, along with railway construction in China high speed development, speed per hour 200km above high standard double track railway
Build more and more, the many factors such as especially in western mountainous areas, circuit show line is big by sweep, topographic and geologic complicated condition
Restriction, length of tunnel, scale increase sharply.Especially in karst area, grow due to karst and subsoil water and there is complexity, various
The feature such as property and irregularities, it is more and more higher that major long tunnel builds risk particularly operations risks.
In recent years, there occurs during suitable ten thousand, Shanghai elder brother, the expensive Railway Tunnel operation such as extensively some ballastless track bed deformation,
Inverted arch and fill the water damage event such as protuberance, lining side wall (generally abutment wall substrate to upwards two meters of scopes within) cracking, causes
Railway Design, construct, build and run the great attention of each side.
Tradition double track tunnel lining cutting typically uses the liner structure form of bent wall band inverted arch, and inverted arch uses Concrete Filled
As railway roadbed basis, in construction, inverted arch is filled with inverted arch and is separately poured.Central drain+bilateral ditch, middle edema with the heart involved are set in tunnel
Ditch is placed in the obturator on inverted arch.Underground water discharge path is: country rock → preliminary bracing → draining blind pipe → lateral sulcus → horizontal stroke
Tunnel is entered by preliminary bracing infiltration via draining blind pipe ejectment to drain pipe → Central drain, the i.e. water of tunnel structure periphery
Central drain within structural body, outside final discharge hole.The defect of conventional drainage systems maximum is: Central drain is located at tunnel
Within road structure, the periphery subsoil water of main ejectment main ejectment arch wall scope, the hydrops below tunnel inverted arch cannot effectively draw
Row.Especially in the close region of ground hydraulic connection, under continuous rainfall or rainstorm weather, because of groundwater run off abruptly increase, traditional
Drainage system often cannot ejectment in time in the gutter in tunnel structure body, thus cause level of ground water drastically to raise.?
Under high hydraulic pressure effect, cause inverted arch at the bottom of tunnel or inverted arch to fill protuberance, thus destroy ballast bed structure.
Therefore, optimize liner structure and drainage system, it is ensured that draining is unobstructed, reduce even eliminate side wall lining behind and
Tunnel bottom water pressure, becomes reduction tunnel, karst area water damage risk, it is ensured that operation security in the urgent need to.
Summary of the invention
The technical problem to be solved is to provide a kind of frame and props up arched tunnel lining structure, to be prevented effectively from rain flood
Season subsoil water increase severely but discharge capacity deficiency causes abutment wall structure crack to destroy, reduce even elimination subsoil water to tunnel-liner
The effect of polycrystalline substance, and then eliminate the rain flood subsoil water in the season destruction risk to liner structure.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Frame of the present invention props up arched tunnel lining structure, including arch wall preliminary bracing structure, secondary liner structure be positioned at two
Waterproof and water drainage system between person, secondary liner structure includes crown section, abutment wall section and inverted arch section, it is characterized in that: described abutment wall section
Structure is propped up, as the carrying structure of crown section for abutment wall frame；Described inverted arch section is the tunnel bottom framework structure with internal cavities, tunnel
The end face of bottom framework structure lays base plate；The hoop port of described waterproof and water drainage system guides the internal cavities of tunnel bottom framework structure into.
The invention has the beneficial effects as follows, use frame to prop up arch lining structure and replace tradition liner structure form, as arch
The carrying structure of secondary lining, substitutes abutment wall secondary lining form concrete in tradition lining cutting, can save concrete, the most favorably
In abutment wall ground water discharge behind；Under tunnel floor, frame structure system is set, can guarantee that at the bottom of tunnel, draining is unobstructed, subsoil water not with
Tunnel floor is directly had an effect, it is to avoid traditional lining cutting causes suitable due to spilled water hole impeded drainage at the bottom of abutment wall or drainability deficiency
Inverted arch hydraulic pressure is uprushed and is caused tunnel bottom structure to destroy；Realizing the external draining of liner structure, arch wall scope subsoil water is introduced directly into tunnel
In space under road base plate, it is prevented effectively from tradition lining cutting and pours in owing to rain flood subsoil water in season excessive lateral sulcus drainability is inadequate
In railway roadbed, it is ensured that the smooth and easy eliminating of subsoil water and avoid causing tunnel bottom structure cracking protuberance.
