Description
Technical field
The utility model belongs to roadway construction protection technology field, more particularly to a kind of roadway construction workbench.
Background technology
Often using double-deck shotcrete rock bolt wire mesh support in roadway construction, i.e., after an individual layer shotcrete rock bolt wire mesh support certain time is completed
Second of individual layer shotcrete rock bolt wire mesh support is carried out again, and secondary supporting must be carried out on the workbench manually set up temporarily, set up temporarily
Workbench will fully take up lane space, support work progress during cause traffic can not be by tunnel.Together
When, when personnel or vehicle have to enter into progress operation in high large empty area, because without effective safeguard procedures, causing such
There is very big potential safety hazard in work.
Utility model content
The purpose of this utility model is to provide a kind of roadway construction workbench to solve to make during the secondary supporting of tunnel
Workbench hinder traffic by with personnel's vehicle into high large empty area operation there is potential safety hazard the problem of.
In order to solve problem above, the technical solution adopted in the utility model is：
A kind of roadway construction workbench, including the protection network set on Vierendeel girder and Vierendeel girder, Vierendeel girder are surrounded by
Supporting construction and cat ladder are additionally provided with the guardrail of flexible connection, Vierendeel girder.
In order to further realize the utility model, Vierendeel girder includes the reinforcement set in cycle beam and cycle beam.
In order to further realize the utility model, the top of supporting construction and the four of Vierendeel girder angles are fixed by socket.
In order to further realize the utility model, supporting construction includes at least four columns, and the bottom of column is set at least
Joined end to end between one elongate posts, column by flange.
In order to further realize the utility model, guardrail is articulated with cycle beam.
In order to further realize the utility model, cat ladder is movable suspension cat ladder or fixed vertical ladder.
In order to further realize guardrail is not provided with the utility model, the cycle beam on cat ladder top.
The utility model has the advantages that：
The utility model is formed by the firm connection of rigid material, and general safety is reliable；Device can be split, and be readily transported and turned
Move, also allow in underground construction Assembling；One passage can be formed at the device bottom after assembling, be available for pedestrian, vehicle to pass through,
Top is a workbench, can carry out supporting operation, and the tunnel traffic capacity is not influenceed when carrying out secondary supporting operation；Dress
Put using in trackless equipment integral shift to high large empty area, personnel, plant equipment can be under the protections of workbench in dead zone
Interior carry out construction operation, eliminates dead zone job safety hidden danger.

Embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
A kind of roadway construction workbench as shown in Figure 1, including Vierendeel girder 1, Vierendeel girder 1 include cycle beam 6 and cycle beam 6
Protection network 2 is set on the reinforcement 7 of interior setting, Vierendeel girder 1, and Vierendeel girder 1 is surrounded by the guardrail 3 of flexible connection, and guardrail 3 is hinged
In on cycle beam 6, being additionally provided with supporting construction 4 and cat ladder 5 under Vierendeel girder 1, the top of supporting construction 4 and four angles of Vierendeel girder 1
Connection, supporting construction 4 includes at least four columns 8, and the bottom of column 8 is set to be passed through between at least one elongate posts 9, column
Flange 10 joins end to end, and cat ladder 5 is the movable suspension cat ladder or fixed vertical ladder that can extend, the outer ring on the top of cat ladder 5
Guardrail 3 is not provided with beam 6.
Before operation, all parts of the present utility model transport is transferred to scene and assembled.
Carry out before secondary supporting operation, the utility model is transported to job location first with trackless equipment, hangs and climbs
Ladder 5 simultaneously props up guardrail 3 of the folds flat in workbench upper surface, and workmen carries out secondary supporting on the workbench of top
Construction operation, lower passage is used for pedestrian and vehicle pass-through.
Into before the construction of dead zone, the utility model is pushed into dead zone first with facility, then workmen, equipment can be entered
Enter dead zone, construction operation is carried out under the protection of workbench.
