Description
Technical field
The present invention relates to traffic engineering technical field, and in particular to a kind of prefabricated supporting for large-deformation tunnel in soft rock is served as a contrast
Build structure and construction method.
Background technology
Large-deformation tunnel in soft rock, due to stress direction, the attitude of rocks, stratigraphic structure, the soft or hard inequality in rock stratum, underground water etc.
The comprehensive function of various factors, often shows as deflection greatly, the deformation duration is long, supporting construction stress is complicated in construction,
It will bear to act on from different directions, different size of pressure from surrounding rock, traditional combined bolting and shotcrete structure is from performing to giving full play to
Its maximum efficiency generally requires the regular hour, before gunite concrete gives full play to efficiency supporting construction integral rigidity compared with
It is weak, it is impossible to enough rigidity is provided in time and supporting construction is tended to occur in soft rock large deformation, construction is not up to design to resist
Before intensity, it is local first occur gunite concrete crack and flake off, steelframe bending, distortion and the problems such as unstability, and then cause
Supporting construction loses bearing capacity in advance.Therefore, develop that to be capable of the supporting construction of fast onset its load-carrying properties be the big change of soft rock
In shape tunnel the problem of a urgent need to resolve.
The content of the invention
It is an object of the invention to provide a kind of prefabricated support lining structure and construction method for large-deformation tunnel in soft rock,
Reduce to greatest extent because supporting construction is further exacerbated by the risk of deformation not in time, caused by early stage support rigidity is not enough.
The technical solution adopted in the present invention is：
Prefabricated support lining structure for large-deformation tunnel in soft rock, it is characterised in that：
Prefabricated support lining structure is built armored concrete secondary liner structure by prefabricated pipe chip preliminary bracing structure and mould and constituted；
Prefabricated pipe chip preliminary bracing structure is assemblied to form by the unit section of jurisdiction of some prefabrications, unit section of jurisdiction it is horizontally-spliced into
Ring, each ring is longitudinal spliced into pipe along tunnel axis direction.
The unit section of jurisdiction of prefabricated pipe chip preliminary bracing structure assembling construction in tunnel, is interconnected into by bolt
Ring.
Space internal pressure water filling cement mortar between prefabricated pipe chip preliminary bracing structure and stratum body, makes prefabricated pipe chip
Preliminary bracing structure is in close contact with stratum body.
Mould builds armored concrete secondary liner structure and is segmented one-piece casting along tunnel axis direction.
Prefabricated pipe chip preliminary bracing structure interior surface lays waterproof layer.
Construction method for the prefabricated support lining structure of large-deformation tunnel in soft rock, it is characterised in that：
Comprise the following steps：
Step one：Stratum body is excavated along tunnel contour, after the completion for the treatment of that stratum body is excavated, section of jurisdiction is used in its inner surface immediately
Assembling machine assembly prefabricated pipe chip preliminary bracing structure；
Step 2：After prefabricated pipe chip preliminary bracing structure assembly is finished, by stratum body inner surface and prefabricated pipe chip
Space internal pressure water filling cement mortar between preliminary bracing structural outer surface, it is ensured that stratum body and prefabricated pipe chip preliminary bracing knot
Structure is closely connected；
Step 3：After pressure injection cement mortar is finished, waterproof layer is laid in prefabricated pipe chip preliminary bracing structure interior surface；
Step 5：After waterproof layer laying is finished, the secondary lining of armored concrete is built in waterproof layer inner surface segmentation one-piece casting mould
Build structure.
The present invention has advantages below：
The present invention is used in high ground stress soft rock stress large deformation tunnel, by prefabricated pipe chip preliminary bracing structure, cast in place reinforced bar coagulation
Native secondary liner structure and its waterproof layer composition between the two, prefabricated preliminary bracing structure can realize that batch production is prefabricated, scene
Assembly, do mechanization operation degree is high, and prefabricated piecemeal can be adjusted according to structure stress and construction, be passed through between prefabricated section
Bolt connection, can be achieved quick-assembling, and realization is quickly performed, and the effect that supporting construction undertakes stratum load be played as early as possible, in tunnel
Road can realize immediate support after excavating, and supporting construction bearing capacity is given full play to as early as possible, and effectively reduction is because of early stage support rigidity
Deficiency causes the risk for being further exacerbated by deformation.

Embodiment
With reference to embodiment, the present invention will be described in detail.
A kind of prefabricated support lining structure for large-deformation tunnel in soft rock of the present invention, by prefabricated pipe chip initial stage
Supporting construction 2 and mould are built armored concrete secondary liner structure 5 and constituted.Prefabricated pipe chip preliminary bracing structure 2 is by some factories
Prefabricated unit section of jurisdiction is assemblied to form, and the horizontally-spliced cyclization in unit section of jurisdiction, each ring is longitudinal spliced into pipe along tunnel axis direction.
The unit section of jurisdiction of prefabricated pipe chip preliminary bracing structure 2 assembling construction in tunnel, is interconnected into by bolt
Ring.Space internal pressure water filling cement mortar between prefabricated pipe chip preliminary bracing structure 2 and stratum body 1, at the beginning of making prefabricated pipe chip
Phase supporting construction 2 is in close contact with stratum body 1.Mould is built armored concrete secondary liner structure 5 and is segmented along tunnel axis direction
One-piece casting.The inner surface of prefabricated pipe chip preliminary bracing structure 2 lays waterproof layer 4.
Work progress is：
Along tunnel contour after the excavation of stratum body 1, immediately in inner surface assembling construction prefabricated pipe chip preliminary bracing structure 2；
