Description
Technical field
The present invention relates to a kind of constructing device of tunnel-liner, and in particular to a kind of for the seamless of Tunnel Second Lining
Stopend.
Background technology
With the extensive construction of Tunnel Engineering, tunnel double-lining popularity is carried out using lining trolley.But due to
In Modern Traffic, to prevent the underground water destruct lining concrete in tunnel, generally in first branch concrete surface and two lining concrete
Between set layer of non-woven fabric and waterstop.When two linings are applied, the termination of lining trolley carries out termination envelope using combination plank sheathing
It is stifled.In view of the first concavo-convex situation of branch concrete surface, two linings easily cause closure leakiness and the situation of spillage occur when applying；Plug
There is plank sheathing certain rigidity to easily cause splash guard or waterstop damage；Needed sealing using general gang form closure termination
Band is folded into an angle of 90 degrees, and waterstop destruction or crooked is buried in easily causing.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of seamless stopend for Tunnel Second Lining, solves tunnel
Leakiness is blocked when road secondary lining is applied, easily the situation of spillage occurs, it is to avoid spillage.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of seamless stopend for Tunnel Second Lining, including circular arc support base and the rubber of circular arc
Air bag；Support base is arranged on the steel form of lining trolley top nose, and rubber pneumatic bag is arranged at just branch lining cutting with support bottom
Between seat and in squeezed state.
According to such scheme, also including push rod fixture and spiral ejection pin；Push rod fixture is connected horizontally on the side of support base
Front, spiral ejection pin is passed perpendicularly through push rod fixture and is fixed by runner.
According to such scheme, the top of the spiral ejection pin is provided with buffer rubber gasket.
It is additionally provided with is buried with according to such scheme, in the support base and bury in sealing belt shape identical waterstop positioning
Frame.
Compared with prior art, the beneficial effects of the invention are as follows：It is combined with lining trolley using rubber pneumatic bag and is used,
Tight of the energy effective guarantee just between the concavo-convex gunite concrete face of branch lining cutting and the steel form of lining trolley is close to closure, keeps away
The problem of imprecision caused by conventionally employed plank sheathing closure termination and spillage is exempted from.
Brief description of the drawings
The specific embodiment invented is described further below in conjunction with the accompanying drawings, wherein：
Fig. 1 is operating diagram of the present invention when Tunnel Second Lining is applied；
Fig. 2 is the enlarged drawing of I part in concrete structure schematic diagram of the invention, i.e. Fig. 1.
Each label is interpreted as in figure：1- just branch lining cutting, 2- secondary linings, 3- back of the body patch waterstops, 4- steel forms are buried in 5-
Waterstop, buries waterstop locating rack, 7- joint fillers, 8- push rod fixtures, 9- spiral ejection pins, 10- buffer rubber gaskets, 11- in 6-
Rubber pneumatic bag, 12- non-woven fabrics, 13- support bases.
Specific embodiment
The present invention is arranged at the front end of lining trolley, including support base 13 and rubber pneumatic bag 11, support base 13 and rubber
The circumferentially disposed front end in lining trolley of glue air bag 11.The lower section of first branch lining cutting 1 in tunnel is connected with non-woven fabrics 12 in turn and the back of the body is pasted
Waterstop 3.The end surface of steel form 4 is connected with support base 13, and the top of support base 13 is provided with buries the shape of waterstop 5 with
Waterstop locating rack 6 is buried in identical, in bury during waterstop 5 is arranged at and bury waterstop locating rack 6, rubber pneumatic bag 11 is arranged at
In bury waterstop 5 and the back of the body patch waterstop 3 between and be in squeezed state.In bury waterstop 5 and be sandwiched in support base 13 and rubber
Between air bag 11, therefore 90 degree need not be folded into secondary lining 2 is applied, bury waterstop 5 in effectively preventing and damaged
It is bad.Rubber pneumatic bag 11 is used in combination with lining trolley, can the concavo-convex gunite concrete face of branch lining cutting 1 at the beginning of effective guarantee and lining cutting platform
Tight is close to closure between the steel form 4 of car, it is to avoid imprecision caused by conventionally employed plank sheathing closure termination and leak
The problem of slurry.The veneer of support base 13 and rubber pneumatic bag 11 is clamped simultaneously, and bury in combining waterstop locating rack 6 reached it is solid
The effect of waterstop 5 and back of the body patch waterstop 3 is buried in fixed.Termination is blocked due to instead of original plank sheathing with rubber pneumatic bag 11,
Realize that waterstop 5 is buried in centering and the softness of back of the body patch waterstop 3 being close to without sky, it is to avoid bury waterstop 5 in locking plug template destruction
With the problem of back of the body patch waterstop 3.
Also include push rod fixture 8 and spiral ejection pin 9.Push rod fixture 8 is connected horizontally on the side front of support base 13, spiral
Push rod 9 is passed vertically through push rod fixture 8 and can be fixed by the runner of push rod fixture 8.By the support of spiral ejection pin 9, make rubber
Air bag 11 can bear the coagulation earth lateral pressure of secondary lining 2.Buffer rubber gasket 10 is additionally provided with the top of spiral ejection pin 9, can be had
Effect avoids spiral ejection pin 9 from destroying back of the body patch waterstop 3.
Simple structure of the present invention, can have strong operability, it is convenient to assemble and disassemble, cheap, with very wide application prospect.
