Abstract
The utility model discloses a plugging device in prevention tunnel vault pitted skin cavity, including removable cover, removable cover one end is articulated with the template roof, and the other end is for can dismantle the free end of being connected with the template roof, and the middle part is close to template one side and is equipped with the shutoff boss that is used for the trompil of shutoff template. The utility model discloses can effectual anti -leakage in advance, the plugging device scheduling problem that drops, improved the concreted structure aesthetic property, and easy operation is feasible to can reduce construction cost.
Description
Technical field
This utility model is related to technical field of tunnel construction, specially a kind of closure dress in prevention tunnel vault pitted skin cavity
Put.
Background technology
Pre-buried channel flow is the parts supporting contact net in railway construction, for the Tunnel Engineering of railway.Conduit is with pre-buried
Mode pours in concrete, fixes for contact net, signal of communication and power equipment.Pre-buried channel flow can be used as cast-in-place, prefabricated mixed
The preferable scalable solution of anchor point is carried on solidifying soil component.
Before pre-buried channel flow construction, according to the position of design requirement, bolt positioning hole to be opened on two lining formwork jumbos, single
At conduit at least perforate two, to reduce template the number of openings as far as possible as principle.When have pre-buried channel flow construction when, t type bolt with
In template, institute's hole-opening connects closure, and has filled and process in conduit, is not in spillage situation；Construct when there is no pre-buried channel flow
When, how to wrap up in stopper using non-woven fabrics at present and institute's hole-opening in template is blocked.Wrap up in stopper this closure mode with non-woven fabrics
There is spillage, the shortcomings of tamper easily comes off.
Utility model content
It is to provide one kind can be seamlessly connected with template for the problems referred to above the purpose of this utility model, can effectively pre- leakproof
The plugging device in the prevention tunnel vault pitted skin cavity of the problems such as slurry and tamper fall.Technical scheme is as follows:
A kind of plugging device in prevention tunnel vault pitted skin cavity, including removable cover, removable cover one end and template top
Wall is hinged, and the other end is the free end being detachably connected with template roof, and middle part is provided with for stopend near template side
The closure boss of perforate.
Further, described free end is provided with u-shaped groove, and u-shaped groove is engaged with the fixing bolt being arranged on template roof,
And fixed by fixing nut.
Further, described fixing bolt is t type, and crossbar sections pass through the hinge hole being fixed on template roof, erect
Bar part is engaged with u-shaped groove.
The beneficial effects of the utility model are: this utility model can be seamlessly connected with template, robust, and simple to operate
Feasible, can be the problems such as effectively pre- mortar leakage prevention, plugging device come off；It is effectively reduced anthropic factor vault lining cutting may be made
The pitted skin cavity becoming, improves concrete surface aesthetic property；And reusable edible, effectively reduce construction cost.

Specific embodiment
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.As shown in figure 1, a kind of prevention tunnel
The plugging device in road vault pitted skin cavity, including removable cover 3, removable cover 3 one end is hinged with template 1 roof, and the other end is
The free end being detachably connected with template 1 roof, the closure that middle part is provided with for stopend perforate 2 near template 1 side is convex
Platform 31.
Removable cover 3 need use when turn on it is not necessary to when just block, open mode is as shown in Figure 1.Live
Setting closure boss on dynamic cover plate 3, can make cover plate and the template surface smooth-going of two lining chassis be connected, radian is consistent, can be effectively anti-
Leak-stopping is starched, it is to avoid the generation in pitted skin cavity.
The free end of the present embodiment is provided with u-shaped groove 32, and u-shaped groove 32 is blocked with the fixing bolt 4 being arranged on template 1 roof
Close, and fixing by fixing nut 5.This fixed form is opened simple and convenient with closed procedure.
The fixing bolt 4 of the present embodiment is t type, and crossbar sections pass through the hinge hole being fixed on template 1 roof, montant portion
Divide and engage with u-shaped groove 32.Montant part can be around crossbar sections left rotation and right rotation, easy disassembly.
When needing closure, first removable cover 3 is covered, then montant part vertical formwork diapire during rotary fixing screw bolt 4,
Then tighten fixing nut；When needing to open, unclamp fixing nut, fixing bolt 4 is rotated to side, open removable cover 3
?.This closure mode is firm firm, does not result in coming off of plug.
