Description
Technical field
The present invention relates to tunnel lining trolley end head formwork technical field of construction, specially a kind of combination tunnel lining trolley
Hold the method for embedding of mould and waterstop.
Background technique
Road and rail tunnel is built frequently with New Austrian Tunneling Method, that is, first carries out initial support to tunnel excavation face after excavating, so
After-pouring inverted arch, finally the two lining trolley of arrangement in tunnel, carries out pouring for secondary lining.Since two lining trolley length are limited
, it is poured so the secondary lining in tunnel is all segmented, this is resulted between two adjacent section concretes, and there are gaps, easily
Percolating water.Current way is buried water stop in being arranged between two section concretes.In the prior art, generally all pass through reinforcing bar
Card is fixed, and reinforcing bar card takes a long time when welding and pad connecting line is difficult to ensure on same circular arc line, and waterstop installs matter
Amount is difficult to ensure.
Trolley end mould is generally using full plank sealing end or steel end mould in such a way that plank combines.Steel end mould there is needs
Repeat the problem of dismounting；Carry out assembled closure using plank, there is also many problems: the heat of hydration of concrete makes plank heated
Deformation, so that timber recycling rate of waterused is very low, and then leads to the waste of a large amount of timber；Assembled and disassembly process is very troublesome, takes
When it is laborious, spin out the duration；It is rough just to prop up the sealing end poor effect so that timber, lead to the problem that spillage is serious；Plank
It is lower to block too loose lateral pressure, the easy spillage of concrete, plank blocks too tight easy damaged splash guard, and it is hidden in turn result in tunnel leak
Suffer from.
For hole after two backings of filling and end concrete damage is repaired, vault band is molded into sizing process using more, this is just
It is required that trolley end mould can be provided biggish lateral pressure to prevent concrete destruction at not-go-end mould.And traditional wooden end mould or steel wood
In conjunction with end mould cannot provide larger lateral pressure since there are more splicing seams for wood board splicing, when vault band is molded into slurry
Easy spillage causes concrete damage at the mould of end.
Summary of the invention
In view of above-mentioned background technique, it is an object of the invention to: provide a kind of tunnel double-lining steel capsule locking plug template and its
Application method quickly blocks end, can provide biggish lateral pressure and guarantee that vault band is molded into the progress of sizing process, have
The embedded quality of buried water stop in effect guarantee meets Tunnel Second Lining Construction requirement to reach；Overturning can be realized again, torn open
Dress is flexible, reduces construction procedure.

Top can contradict the connection support card slot, so that the vertical beam be driven to swing and adjust the angle around the installation free bearing.Its
In, cylinder, oil cylinder etc. can also be used using screw mechanism automatically or semi-automatically in the telescoping mechanism.
Baffle is additionally provided in the vertical beam, the baffle, supporting table and vertical beam form chamfer triangle, stabilized structure
Reliably.
The lever fixture includes runner and casing, and described sleeve pipe connects the lever or vertical beam, when work the runner
Spiral, which is transferred in described sleeve pipe, holds out against the lever or vertical beam, and other retaining mechanisms (such as lock-screw) also can be used and replace
It changes.
The lacing for facilitating several spacing of positioning to arrange is additionally provided between the lever and the vertical beam.
Each air bag includes airbag body, air bag protective layer and charge and discharge gas nozzle, and the air bag protective layer coats air bag
Ontology, and closely coupled common stretch of the two does not depart from；Charge and discharge gas nozzle is in air bag protective layer, and communicated air bags ontology.
The upper and lower surfaces of each air bag are equipped with the radian being centainly consistent with tunnel/sealing belt shape, section
Face is the rectangle that quadrangle is in arc side, has certain height.
The upper and lower surfaces of each air bag are also respectively with the velcro for facilitating fitting to stack.
It is additionally provided with the positioning ring for matching the lever on each air bag, lever passes through all air bags when use
Positioning ring is positioned.
The present invention also provides a kind of method for embedding of waterstop to be led to using a kind of above-mentioned combination tunnel lining trolley end mould
It crosses installation free bearing and steel end mold device and adjusting supporting device is mounted on the front end of lining trolley by connecting rod respectively, adjust institute
The top for stating telescoping mechanism, which contradicts, connects the support card slot, so that the end face direction lining cutting side to be poured of supporting table, it will
Middle buried water stop is placed in supporting table, and the number of air bag is arranged according to two liner thickness degree of concrete engineering, and air bag is stacked and is placed
On middle buried water stop, the height of up and down adjustment lever makes locating piece hold out against one end of back-adhering waterstop, then passes through
The position of the fixed lever of the lever fixture；Last air bag inflation compress in buried water stop and back-adhering waterstop until
Grouting process finishes.
The beneficial effects of the present invention are:
