Description
Technical field
The utility model belongs to Tunnel field, in particular to a kind of sliding formwork just serves as a contrast the dual-purpose trolley of excavation supporting.
Background technique
In the prior art, preliminary bracing form concrete is all made of small-sized punching block all the time and is assembled into Tunnel
Profile after, then casting concrete formed one facings of preliminary bracing.There are more safe mass hidden danger for this method.Prepare first
It works more, needs to prepare the equipments such as small-sized punching block, type steel support;Secondly process is tedious, according to the profile in design tunnel when construction
The vertical type steel support of branch, then block-by-block is assembled by small-sized punching block, is connected and fixed, and after completion pours, when demoulding needs block-by-block by small fashioned iron
Mould percussion falls off;It is that safe mass is difficult to control again, on the one hand assembled small-sized punching block inevitably will appear piece, be not fixed firmly and lean on
The problems such as, another aspect construction personnel is more, and assembling duration is long, and personnel are long in the time that face stays, and security risk increases.Most
Construction speed is slow afterwards, and tunnel tunnel face formula confined space construction, supporting in the early stage one serves as a contrast form concrete and is not finished, must not be into
Enter next procedure, and the support frame that excavation supporting uses is conflicted with each other with trolley is excavated, can not be used simultaneously in face.
Utility model content
The purpose of this utility model is to provide a kind of sliding formworks just to serve as a contrast the dual-purpose trolley of excavation supporting, realizes that just lining concrete is applied
Work slipform process, and it is supporting rack that trolley door frame is simultaneous, reduces labor workload, shortens construction personnel in the Sojourn times of face
Between, improve safety guarantee.
To achieve the goals above, the utility model takes following technical scheme: it is dual-purpose that a kind of sliding formwork just serves as a contrast excavation supporting
Trolley, including trolley, the trolley include door frame and the rubber traveling wheel connecting with door frame, the upper surface edge of the door frame
The length direction of trolley is provided with sliding rail, and support plate is provided on the sliding rail, be provided with below the support plate with
The idler wheel of sliding rail cooperation, the both ends of the support plate are connect with the intrados of semi-circular top bar template, and described appears on the stage
The both ends in the arc length direction of rank template are in the outside of the two sides of the length direction of trolley.
The door frame includes the horizontally disposed main longitudinal grider of length direction along trolley, and the rubber traveling wheel and master are vertical
Beam connects, and is vertically connected with vertical beam on the main longitudinal grider, and the upper end of the vertical beam is connect with top plate, the sliding rail arrangement
In on top plate.
It is connected with reinforcing beam between the vertical beam, is provided with main jacking cylinder between the reinforcing beam and main longitudinal grider,
It is connected with support base on the outside of the vertical beam, is provided with secondary jacking cylinder between the support base and main longitudinal grider.
Support lower margin is provided between the main longitudinal grider and ground.
Jack/screw rod, the jack/screw rod are provided between the intrados of the vertical beam and top bar template
Both ends it is hinged with the intrados of vertical beam, top bar template respectively.
Above-mentioned technical proposal has following technical effect that 1, the utility model just serves as a contrast the dual-purpose trolley of excavation supporting with sliding formwork and replaces
For traditional small shape steel plate assembling process, tunnel initial-stage lining concrete Quality Construction progress is increased substantially, is shortened
Support time reduces the labor intensity of worker.2, just the lining dual-purpose trolley of excavation supporting passes through top bar to the utility model sliding formwork
The sliding of template, realize trolley door frame and be supporting rack, solve a lining trolley it is in place when it is conflicting with supporting rack
Contradiction, without setting up interim rack when propping up vertical shaped steel arch, hanging reinforced mesh.3, the utility model sliding formwork just serves as a contrast and excavates branch
Protecting dual-purpose trolley realizes separating between top bar template and rack, reduces a lining concrete and waits concrete strength
Time improves face construction efficiency, reaches design strength when preliminary bracing one serves as a contrast form concrete intensity under normal circumstances
When 70% or more could demoulding, separated by top bar template with rack, top bar template is retained in just provide on branch face it is mixed
Solidifying soil stress greatlys save rack and stops the mechanical time for entering face.
Detailed description of the invention
Fig. 1 is that trolley and top bar template cooperate main view;
Fig. 2 is trolley side view.
Specific embodiment
It is made further instructions in conjunction with Fig. 1,2 pairs of the utility model:
