Brief description
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described in further detail.
Fig. 1 is the anti-dislocation combination support of tunnel structural representation for passing through active fault layer.
Specific embodiment
In order to be illustrated more clearly that the present invention, with reference to preferred embodiments and drawings, the present invention is done further
Bright.In accompanying drawing, similar part is indicated with identical reference.It will be appreciated by those skilled in the art that institute is concrete below
The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
The invention discloses a kind of anti-dislocation combination support of tunnel structure for passing through active fault layer, its feature exists
In this supporting construction includes：Preliminary bracing 1 and the secondary lining 2 being used for supporting is sequentially fixed on tunnel inner wall；Described secondary
Lining cutting 2 is provided with multiple described secondary linings 2 and disconnects, along tunnel direction, the anti-dislocation slit 3 being formed；Solid in described anti-dislocation slit 3
Fixed flexible implant 4；Offer for preventing secondary lining 2 from existing between described secondary lining 2 free face and anti-dislocation slit 3
The wedge structure 6 of abrasion during dislocation.Wherein, the width of described anti-dislocation slit 3 can be 5cm～15cm.
The surface of described preliminary bracing 1 can cover waterproof layer 9, also may be used in waterproof layer 9 surface at described anti-dislocation slit 3
Setting convex hull drainable waterproofing plate 5, described convex hull drainable waterproofing plate 5 is arranged centered on described anti-dislocation slit 3, and it is axially wide along tunnel
Degree more than the width of described anti-dislocation slit 3, its length of run can be 15 times of width of described annular anti-dislocation slit 3 with
On, apply more than 10 times that length can be the width of described annular anti-dislocation slit 3.
At anti-dislocation slit 3, preliminary bracing 1 and secondary lining 2 are likely to occur infiltration and leak after being subjected to displacement
Situation, the waterproof layer 9 grade waterproof measure now adopting in the art do not consider occur dislocation after it may happen that infiltration and leakage
Regimen condition, therefore, can adopt convex hull drainable waterproofing plate 5, described convex hull drainable waterproofing plate 5 is to form multiple bulge-structures along tunnel direction
Thin plate, the material of described convex hull drainable waterproofing plate 5 can adopt silicone rubber or fluorubber.Supporting in the early stage 1 and secondary lining 2 occur
After dislocation, convex hull drainable waterproofing plate 5 can move radially along tunnel together with secondary lining 2 with preliminary bracing 1, but due to raised knot
The presence of structure, during dislocation, its structure can change convex hull drainable waterproofing plate 5 therewith, the pleat on convex hull drainable waterproofing plate 5
Wrinkle structure can flatten first, dislocation will be occurred just to rupture therewith due to preliminary bracing 1 and secondary lining 2, therefore, in a positioning
In wrong scope, the splash guard with anti-dislocation structure still has the effect of waterproof, and structure is simply it is easy to construct.
It is fixed with elastic filler 4, its material can be selected for polyethylene foamss plate or rubber in described anti-dislocation slit 3
Glue, described elastic filler 4 can be filled in anti-dislocation slit 3 with convex hull drainable waterproofing plate 5 intersection it is preferred that described elasticity is filled out
Fill radially fill that thickness is described secondary lining 2 thickness more than 1/3rd of thing 4, inside described elastic filler 4 also
The annular draining blind pipe 7 of draining can be provided for.Described elastic filler 4 combination support of tunnel structure due to Fault Creep or
When there is the axial displacement along tunnel direction in sudden earthquake, secondary lining 2 meeting of anti-dislocation slit 3 both sides under force
Mutually extrude, be provided with elastic filler 4 in described anti-dislocation slit 3, elastic filler 4 has certain decrement, can delay
Punching and the relative motion stoping anti-dislocation slit 3 both sides secondary lining 2, prevent the secondary lining 2 of both sides from colliding.
Described secondary lining 2 also can arrange steel plate water stopper 8 at described anti-dislocation slit 3, and described steel plate water stopper 8 sets
It is placed in elastic filler 4 near tunnel internal side, described steel plate water stopper 8 is spill, concave-shaped openings are filled out towards described elasticity
Fill thing 4, two horizontal ends of spill embed in both sides secondary lining 2 it is preferred that insert depth is more than 20cm.Described steel plate stops
Water band 8 it is also possible to increase the connection of the secondary lining 2 of anti-dislocation slit 3 both sides, reduces secondary lining while playing sealing
2 along tunnel direction displacement, concave-shaped openings structure can prevent from steel plate water stopper 8 from missing in place in journey rupturing at once and produce leakage
Regimen condition.
Offer between secondary lining 2 free face and anti-dislocation slit 3 and grind for during preventing secondary lining 2 mistake in place
The wedge structure 6 damaging it is preferred that wedge structure 6 is 40 °～70 ° of chamfering, it is furthermore preferred that chamfering is 60 °.Described wedge shape knot
The setting of structure 6 can effectively prevent when secondary lining 2 gap of anti-dislocation slit 3 both sides collides produce stress concentration and
Lead to secondary lining 2 that situation about destroying occurs.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not right
The restriction of embodiments of the present invention, for those of ordinary skill in the field, also may be used on the basis of the above description
To make other changes in different forms, all of embodiment cannot be exhaustive here, every belong to this
Obvious change that bright technical scheme is extended out or change the row still in protection scope of the present invention.
