the utility model provides a tunnel landing stage, includes two landing stage bodies that set up relatively, two be the cavity between the landing stage body, be equipped with the reinforcing bar net in the cavity, the reinforcing bar net rotates to be connected the landing stage body, the cantilever of reinforcing bar net with the landing stage body passes through the pull rod to be connected.
According to the tunnel trestle, the cavity is sealed through the reinforcing steel bar net, the reinforcing steel bar net is limited through the pull rod, when the cavity needs to be opened, the reinforcing steel bar net is rotated upwards to be close to the side edge of the trestle body, the reinforcing steel bar net can prevent constructors from stepping down when passing through the trestle body, and meanwhile the constructors below the cavity can be prevented from being injured by dropping objects in the inverted arch construction.
As a preferable technical scheme of the utility model, the reinforcing mesh is rotatably connected to the side wall of the trestle body through a hinge.
As a preferable technical scheme of the utility model, each trestle body is respectively connected with the reinforcing mesh.
As a preferable technical scheme of the utility model, the reinforcing mesh comprises a plurality of segments, the segments are sequentially arranged along the length direction of the trestle body, each segment is rotationally connected with the trestle body, and a cantilever of each segment is connected with the trestle body through at least one pull rod.
As a preferable technical scheme of the utility model, the pull rod is an iron chain, a steel wire rope or a telescopic rod.
As a further preferable technical scheme of the utility model, the pull rod is hinged with the trestle body.
As a preferable technical scheme of the utility model, guardrails are respectively arranged on the outer sides of the two trestle bodies.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
according to the tunnel trestle, the cavity is sealed through the reinforcing mesh, the reinforcing mesh is limited through the pull rod, when the cavity needs to be opened, the reinforcing mesh is rotated upwards to be close to the side edge of the trestle body, the reinforcing mesh can prevent constructors from stepping empty when passing through the trestle body, and meanwhile, the constructors below the cavity can be prevented from being injured by dropping objects in the cavity during inverted arch construction.

Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1
As shown in fig. 2 to 4, the tunnel trestle of the utility model comprises two trestle bodies 1 which are oppositely arranged, and a cavity 2 is arranged between the two trestle bodies 1.
As shown in fig. 2, a reinforcing mesh 3 is disposed in the cavity 2, the reinforcing mesh 3 is rotatably connected with the trestle body 1, a cantilever of the reinforcing mesh 3 is connected with the trestle body 1 through a pull rod 5, specifically, the reinforcing mesh 3 is rotatably connected with the side wall of the trestle body 1 through a plurality of hinges 4, the end of the pull rod 5 is hinged with the trestle body 1, the pull rod 5 adopts flexible connection rods such as an iron chain and a steel wire rope, or adopts movable connection rods such as a telescopic rod, the pull rod 5 pulls the reinforcing mesh 3 to keep a horizontal arrangement, the reinforcing mesh 3 is limited and supported, the flexible connection rods or the movable connection rods can facilitate folding of the pull rod 5, so that the reinforcing mesh 3 can be rotated and folded, and if the pull rod 5 adopts a fixed rod, the pull rod 3 can be rotated after the connecting part of the cantilever of the reinforcing mesh 3 needs to be released.
