Description
Technical field
The utility model is related to tunnel lining structure, more particularly to a kind of the hard rock tunnel or karst region of underground water development
Area's tunnel lining structure.
Background technology
Come into 21st century, with railway construction in China high speed development, speed per hour 200km above high standard double track railways
Build more and more, especially in western mountainous areas, circuit show line is by many factors such as big, the topographic and geologic complicated conditions of sweep
Restriction, length of tunnel, scale increase sharply.Especially in karst area, because karst and underground water development have complexity, various
The features such as property and irregularities, major long tunnel builds risk particularly operations risks more and more higher.
In recent years, suitable ten thousand, be there occurs during Shanghai elder brother, the expensive Railway Tunnel operation such as wide some ballastless track beds deformations,
The water damage event such as inverted arch and filling protuberance, lining side wall (generally within abutment wall substrate to upward two meters of scopes) cracking, causes
Railway Design, construction, build and operation each side great attention.
Traditional double track tunnel lining cutting typically using bent liner structure form of the wall with inverted arch, uses Concrete Filled on inverted arch
Used as railway roadbed basis, inverted arch is separately poured with inverted arch filling in construction.Central drain+bilateral ditch, middle edema with the heart involved are set in tunnel
In the obturator that ditch is placed on inverted arch.Underground water discharge path is：Country rock → preliminary bracing → draining blind pipe → lateral sulcus → horizontal stroke
Permeated by preliminary bracing to drainpipe → Central drain, the i.e. water on tunnel structure periphery and enter tunnel via draining blind pipe ejectment
Central drain within structural body, outside final discharge hole.The maximum defect of conventional drainage systems is：Central drain is located at tunnel
Within road structure, the periphery underground water of the main main ejectment arch wall scope of ejectment, the ponding below tunnel inverted arch cannot effectively draw
Row.It is traditional because of groundwater run off abruptly increase under continuous rainfall or rainstorm weather especially in the close region of ground hydraulic connection
In the gutter that drainage system often cannot be in ejectment in time to tunnel structure body, so as to cause level of ground water drastically to raise.
Under hydraulic pressure effect high, cause tunnel bottom inverted arch or inverted arch filling protuberance, so as to 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 hydraulic pressure, as reduce karst area tunnel water damage risk, it is ensured that operation security in the urgent need to.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of frame branch arched tunnel lining structure, to be prevented effectively from
Rain flood season underground water increases severely but discharge capacity deficiency causes abutment wall structure crack to destroy, and reduces and even eliminate underground water to tunnel
The effect of lining cutting polycrystalline substance, and then eliminate destruction risk of the rain flood season underground water to liner structure.
It is as follows that the utility model solves the technical scheme that its technical problem used：
The utility model frame branch arched tunnel lining structure, including arch wall preliminary bracing structure, secondary liner structure and position
In waterproof and water drainage system between the two, secondary liner structure includes crown section, abutment wall section and inverted arch section, it is characterized in that：The side
Wall section is abutment wall frame branch structure, used as the bearing structure of crown section；The inverted arch section is the tunnel bottom framework knot with internal cavities
Structure, the top surface laying base plate of tunnel bottom framework structure；The ring port of the waterproof and water drainage system guides the inside of tunnel bottom framework structure into
Cavity.
The beneficial effects of the utility model are to replace traditional liner structure form using frame branch arch lining structure, as
The bearing structure of arch secondary lining, substitutes abutment wall secondary lining form concrete in traditional lining cutting, can save concrete, and
Be conducive to the ground water discharge of abutment wall behind；Frame structure system is set under tunnel floor, can guarantee that the draining of tunnel bottom is unobstructed, underground water
Do not had an effect directly with tunnel floor, it is to avoid traditional lining cutting is not enough due to abutment wall bottom spilled water hole impeded drainage or drainability
Suitable inverted arch hydraulic pressure is caused to uprush and cause tunnel bottom structure to destroy；The external draining of liner structure is realized, arch wall scope underground water directly draws
Enter in the space under tunnel floor, be prevented effectively from traditional lining cutting because the rain excessive lateral sulcus drainability of flood season underground water is inadequate
Pour in railway roadbed, it is ensured that the smooth exclusion of underground water and avoiding causes tunnel bottom structure to ftracture protuberance.
