Description
Technical field
Railway tunnel is the utility model is related to, more particularly to a kind of Tunnel Passing active fault section lining structure.
Background technology
China is the multiple country of an earthquake.With moving forward steadily for national the Belt and Road strategy, domestic communication is built
If having welcome fast-developing period, the tunnel for passing through active breaking belt is more and more.Weight of the tunnel as transportation lifeline engineering
Want part, keep unimpeded under the conditions of macroseism or can rob in time it is logical to shake after earthquake relief work and restoration and reconstruction have it is important
Meaning.
A large amount of Disaster Datas show, active fault due to country rock is weak, stress concentration is obvious, after hair shake with obvious
The feature such as creep, Lining cracks, faulting of slab ends easily occur after macroseism, concrete scaling, the disease such as collapse, are the concentration of tunnel earthquake
Position and antidetonation weak link.Active fault tunnel earthquake is passed through mainly to be caused by two kinds of factors of seismic shock and fault movement,
Wherein fault movement is principal element, and the lining section vault contact after fault movement close to tomography will be multiplied.
At present both at home and abroad to passing through the antidetonation in active breaking belt tunnel, glissando has done substantial amounts of research and engineering is real
Trample, mainly have lining cutting back-grouting reinforce country rock, expand tunnel cross-section size with ensure the tunnel cross-section area after fault movement,
Along longitudinally disposed absorbing joint in tunnel etc., but to the error resilience set up defences between lining cutting and non-lining cutting of setting up defences of tomography both sides is disconnected, waterproof measure
Research and application are relatively fewer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Tunnel Passing active fault section lining structure, to have
Effect reduces faulting in additional stress caused by lined internal, and effective guarantee is provided for railway operation is safe.
Technical scheme is as follows used by the utility model solves its technical problem：
Tunnel Passing active fault section lining structure of the present utility model, including common antidetonation outside active fault are set
Anti- section of lining cutting, it is characterized in that：Active breaking belt lining cutting is set in the active fault, and section lining cutting of commonly providing fortification against earthquakes is broken with activity
The joint for being set with the adjacent one end of lining cutting and consolidating and being integrated with it is split, between the joint end face relative with active breaking belt lining cutting
Expansion joint is set, water sealing structure is set in expansion joint；The common section lining cutting of providing fortification against earthquakes, the vertical section of joint are L-shaped, joint
Outline it is consistent with the outline of active breaking belt lining cutting, Internal periphery and the activity of commonly provide fortification against earthquakes section lining cutting and joint
Reserved displacement space is formed between fracture belt lining cutting Internal periphery.
The beneficial effects of the utility model are can to effectively reduce faulting in additional stress caused by lined internal, increasing
The rigidity of adjunction head, structure error resilience kinetic force is strong, and can solve the leakage problem of joint caused by fault movement,
Structural shape easy construction, effective guarantee is provided safely for railway operation, Social benefit and economic benefit is obvious.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is the floor map of the utility model Tunnel Passing active fault section lining structure；
Fig. 2 is in the utility model Tunnel Passing active fault section lining structure；
Component and corresponding mark are shown in figure：Common provide fortification against earthquakes a section lining cutting L1, joint L2, active breaking belt lining cutting
L3, expansion joint L4, reserved displacement space K, buried galvanized steel plain sheet waterstop 10, polysulfide building sealant 11, external labeling type plastics stop
Water band 12, polyethylene foams plate 13.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, Tunnel Passing active fault section lining structure of the present utility model, including it is general outside active fault
The logical section lining cutting L1 that provides fortification against earthquakes, active breaking belt lining cutting L3 is set in the active fault, commonly provide fortification against earthquakes section lining cutting L1 with
One end adjacent active breaking belt lining cutting L3 sets the joint L2, joint L2 and active breaking belt lining cutting L3 for consolidating and being integrated with it
Expansion joint L4 is set between relative end face, water sealing structure is set in the L4 of expansion joint.The common section lining cutting L1 that provides fortification against earthquakes, connect
Head L2 vertical section is L-shaped, and joint L2 outline is consistent with active breaking belt lining cutting L3 outline, commonly provides fortification against earthquakes
Reserved displacement space K is formed between section lining cutting L1 and joint L2 Internal periphery and active breaking belt lining cutting L3 Internal peripheries.
If routinely designing, active fault sets up defences lining cutting using expanding section, itself and common lining cutting contact position of providing fortification against earthquakes
Faulting of slab ends will be formed, the joint of faulting easily therebetween produces larger stress concentration, increases the probability of earthquake.This reality
L-type joint is used in the less side of rigidity with new, Joint Bending Stiffness adds nearly 4 times, enhances the antidetonation energy of joint
Power, simultaneously because the contact area increase of joint, the error resilience cutting capacity of joint are strong.
Reference picture 2, buried plating during the water sealing structure is embedded in joint L2, active breaking belt lining cutting L3 in advance including both sides
Zinc steel plate water stopper 10, in the section of buried galvanized steel plain sheet waterstop 10 be in Ω types.Galvanized steel plain sheet buried in the L4 of expansion joint
Waterstop 10 is filled out to active breaking belt lining cutting L3 Internal peripheries and sets polysulfide building sealant 11, the buried galvanized steel plain sheet waterstop 10 in
Opposite side fill out and set polyethylene foams plate 13, in pasting outer patch on active breaking belt lining cutting L3 and joint L2 outer surface
Formula plastics waterstop 12.After structure position changing, waterstop is suitable for malformation, adds structurally waterproof reliability.
Some principles of the utility model Tunnel Passing active fault section lining structure described above that simply explains through diagrams,
Be not intended to by the utility model be confined to shown in and described concrete structure and the scope of application in, therefore every be possible to sharp
Corresponding modification and equivalent, belong to the apllied the scope of the claims of the utility model.
