Description
Technical field
The present invention relates to railway tunnel, in particular to a kind of railway tunnel lining knot with Pneumatic effect releasing function
Structure.
Background technique
Strong aerodynamic effects can be generated when High-speed Trains Passing Through Tunnel, the main manifestation mode of the effect has hole
Train parting in interior transient pressure, hole microbarometric wave and hole.Transient pressure can cause passenger's ear-drum pressure sensitivity uncomfortable, reduce passenger and relax
Appropriateness；Hole microbarometric wave will cause Property of Blasting Noise and jeopardize hole building；The train parting that train high-speed cruising generates can be right
Operating personnel to be avoided threatens safely in tunnel.Therefore, it is dynamic to alleviate the air that train generates when high-speed cruising in tunnel
Mechanics effect is most important.Currently, alleviate tunnel aerodynamic effect major measure have expand tunnel cross-section headroom, setting tunnel into
Mouth buffer structure, setting service gallery etc..Engineering cost can largely be increased by expanding tunnel cross-section；It is slow that tunnel entrance is set
Rush structure to hole outside orographic condition require, do not have setting condition in some cases；Service gallery is arranged equally can be by
To the limitation of hole orographic condition, and it will increase engineering cost.For the deficiency of the above measure, need originally to wear from tunnel structure
Hand seeks technical solution.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of railway tunnel linings with Pneumatic effect releasing function
Structure, the aerodynamic effect generated when High-speed Trains Passing Through Tunnel is effectively relieved improve ride comfort and mitigate in tunnel
The influence of external environment.
The technical solution adopted by the present invention to solve the technical problems is as follows:
A kind of railway tunnel lining structure with Pneumatic effect releasing function of the invention, it is characterized in that: tunnel-liner
Structure includes lining of tunnel portal section structure and the barrel section liner structure that is mated with, circumferentially spaced-apart setting in lining of tunnel portal section structure
The air duct longitudinally extended, the inner end that air duct closes on barrel section liner structure are connected with tunnel, and tunnel is then led in outer end
Outside road.
The air duct is provided at circumferentially spaced arch wall section and crown section in lining of tunnel portal section structure.
The air duct is formed by the pvc pipe being embedded in lining of tunnel portal section structure.
The invention has the advantages that being arranged what its inner end was connected with tunnel at lining of tunnel portal section structure inner circumferential interval
The outer end of air duct, air duct is then led to outside tunnel, the sky generated when can effectively alleviate High-speed Trains Passing Through Tunnel
Aerodynamics effect reduces transient pressure peak value in tunnel and compartment, improves ride comfort, while can reduce the micro- air pressure in hole
Crest value mitigates the influence to tunnel exit environment；It is not limited by tunnel portal orographic condition, easy for construction, construction cost
It is low.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is a kind of longitudinal sectional view of the railway tunnel lining structure with Pneumatic effect releasing function of the present invention；
Fig. 2 is a kind of cross-section diagram of the railway tunnel lining structure with Pneumatic effect releasing function of the present invention；
Fig. 3 is a kind of working principle signal of railway tunnel lining structure with Pneumatic effect releasing function of the present invention
Scheme
Component, toponym and corresponding label: lining of tunnel portal section structure 11, barrel section liner structure are shown in figure
12, air duct 13, train L.
Specific embodiment
The following further describes the present invention with reference to the drawings.
Referring to Fig.1, a kind of railway tunnel lining structure with Pneumatic effect releasing function of the present invention, tunnel lining structure
It is circumferentially spaced-apart in lining of tunnel portal section structure 11 to set including lining of tunnel portal section structure 11 and the barrel section liner structure 12 being mated with
The air duct 13 longitudinally extended is set, the inner end that air duct 13 closes on barrel section liner structure 12 is connected with tunnel, outer end
Then lead to outside tunnel.The aerodynamics that the setting of air duct 13 generates when can effectively alleviate High-speed Trains Passing Through Tunnel
Effect reduces transient pressure peak value in tunnel and compartment, improves ride comfort, while can reduce hole microbarometric wave peak value,
Mitigate the influence to tunnel exit environment.Pneumatic effect releasing structure is not limited by tunnel portal orographic condition, easy for construction,
Construction cost is low.
Referring to Figures 1 and 2, the air duct 13 is provided at circumferentially spaced arch wall section and arch in lining of tunnel portal section structure 11
Push up section.Consider from convenient for construction, the air duct 13 is formed by the pvc pipe being embedded in lining of tunnel portal section structure 11, air
The section in channel 13 is circle, a diameter of 0.5~1.0m.
Referring to Figures 1 and 2, comprehensive Pneumatic effect releasing effect, tunnel construction cost consider, the lining of tunnel portal section structure
11 length extended into hole from hole are 30~50m.1.0~1.5m of thickness of the lining of tunnel portal section structure 11, barrel section
Liner structure 12 with a thickness of 0.40~0.55m.I.e. lining of tunnel portal section structure 11 is thickened with respect to barrel section liner structure 12, to hold
Receive the air duct 13 added.
Referring to Fig. 3, when train L high speed enters tunnel, the air that train front is pressurized can be from hole air duct 13
Inner port enters in air duct 13, and flows out outside tunnel portal through 13 external port of air duct, effectively mitigates train L to tunnel
The compression degree of interior air reduces pressure transient amplitude, to achieve the effect that alleviate aerodynamic effect.
The above is a kind of railway tunnel lining knot with Pneumatic effect releasing function of the present invention that explains through diagrams
Some principles of structure are not intended to for the present invention being confined in shown and described specific structure and the scope of application, therefore all institutes
It is possible that the corresponding modification being utilized and equivalent, belong to the applied the scope of the patents of the present invention.
