Abstract
A kind of truss-like tunnel inverted arch liner structure, effectively to enhance the rigidity of structure of tunnel inverted arch, to advantageously reduce the generation of tunnel inverted arch protuberance.Tunnel bottom structure includes Tunnel Second Lining inverted arch section and fills inverted arch filled layer thereon with concrete, and Central drain is arranged in inverted arch filled layer central part.Truss is buried in the inverted arch filled layer, truss is arranged along line direction interval, and bottom end is located in Tunnel Second Lining inverted arch section.
Description
Technical field
The utility model relates to railway tunnel, in particular to a kind of truss-like tunnel inverted arch liner structure.
Background technique
Along with the beginning of national extensive railway construction, northwest is being constructed with southwestern important trunk railway part tunnel
There is different degrees of inverted arch protuberance phenomenon at rear, significant impact is caused safely to railway operation.Part location inverted arch is again
Processing, brings huge difficulty to construction, while also improving engineering cost.Therefore, how to control and handle inverted arch protuberance
Have become the problem of paying high attention in railway tunnel construction.
The complex genesis of inverted arch protuberance, with the formation lithology of Tunnel Passing, underground water developmental state, special geological structure etc.
It is related.Often during railway operation, the reason after inverted arch protuberance occurs is investigated and is handled again for the discovery of inverted arch protuberance
Relatively difficult, the effect of processing is also poor.
Therefore, the detail design stage is directed to the adverse geological condition that may cause tunnel inverted arch protuberance, suitably enhancing tunnel
The rigidity of structure of inverted arch advantageously reduces the generation of tunnel inverted arch protuberance.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of truss-like tunnel inverted arch liner structures, effectively to increase
The rigidity of structure of strong tunnel inverted arch, to advantageously reduce the generation of tunnel inverted arch protuberance.
It is as follows that the utility model solves technical solution used by its technical problem:
A kind of truss-like tunnel inverted arch liner structure of the utility model, tunnel bottom structure include Tunnel Second Lining inverted arch section
Inverted arch filled layer thereon is filled with concrete, Central drain is set in inverted arch filled layer central part, it is characterized in that: facing upward
Encircle and bury truss in filled layer, truss is arranged along line direction interval, and bottom end is located in Tunnel Second Lining inverted arch section.
The utility model has the beneficial effects that burying truss along line direction interval in tunnel inverted arch filled layer, can have
The rigidity of structure of effect enhancing tunnel inverted arch improves ability and safety stock that tunnel inverted arch resists protuberance deformation；Trussmember knot
Structure is simple, can scene perform also can prefabrication assembled in situ construction, it is easy to operate, have good economic serviceability.
Detailed description of the invention
This specification includes such as next width attached drawing:
Fig. 1 is a kind of cross-section diagram of truss-like tunnel inverted arch liner structure of the utility model；
Component and corresponding label: Tunnel Second Lining inverted arch section 11, inverted arch filled layer 12, Central drain are shown in figure
13, truss 14.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of truss-like tunnel inverted arch liner structure of the utility model, tunnel bottom structure include the secondary lining in tunnel
It builds inverted arch section 11 and fills inverted arch filled layer 12 thereon with concrete, the edema with the heart involved in the setting of 12 central part of inverted arch filled layer
Ditch 13.Truss 14 is buried in inverted arch filled layer 12, truss 14 is arranged along line direction interval, and bottom end is located at the secondary lining in tunnel
It builds in inverted arch section 11.The rigidity of structure of tunnel inverted arch can effectively be enhanced by truss 14, tunnel inverted arch is improved and resist protuberance deformation
Ability and safety stock.14 structure of truss is simple, can scene perform also can prefabrication assembled in situ construction, operation side
Just, there is good economic serviceability.
The truss 14 can use steel truss, reinforced concrete truss, prestressed concrete truss or steel-concrete
The other materials such as composite roof truss.
Referring to Fig.1, Central drain 13 is prefabricated by armored concrete in figure, is embedded in inverted arch filled layer 12, and longitudinal direction is worn
Cross 14 inner space of truss.The section configuration of Central drain 13 can also be designed and sized to according to water amount, truss rectangle etc. other
Pattern.
The above is a kind of some principles of truss-like tunnel inverted arch liner structure of the utility model that explain through diagrams,
Shown in being not intended to for the utility model to be confined to and in the specific structure and the scope of application, thus it is all it is all may be sharp
Corresponding modification and equivalent, belong to the applied the scope of the patents of the utility model.
