Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a double - layer traffic lane slab trolley for urban circular tunnels. Background Art

[0002] In the process of urban development, the requirement for traffic flow is getting higher and higher. Some tunnel projects adopt a double - layer layout, with both the upper and lower layers being urban arterial roads. Columns are set on the lower - layer road for the upper - layer road, and then the lane slab is designed on the upper layer.

[0003] During the construction of such projects, after the lower - layer construction is completed, the upper - layer construction is carried out. Due to the design of the columns of the upper - layer lane, sometimes the full - hall support method is used during construction. This construction method has a large construction area, but requires more manpower and material resources.

[0004] Although the current tunnel trolleys can facilitate the operation of workers, their application scope is small, and they cannot make reasonable adjustments for tunnels of different widths. Moreover, due to the space limitation between the tunnel columns and the edge, it is often not a one - time construction, and secondary pouring is mostly used, resulting in low construction efficiency and a cumbersome formwork removal process. Content of the Utility Model

The two movable support plates 4 are respectively slidably installed at both ends of the fixed support plate 3. Thrust mechanisms are installed at both ends of the upper part of the trolley body 1, and the thrust mechanisms are used to drive the movable support plates 4 at the same side position to move. The two L-shaped flap plates 5 are respectively movably hinged and installed at the outer ends of the two movable support plates 4. A stay cylinder 13 is movably hinged and installed at the lower part of the L-shaped flap plate 5, and the other end of the stay cylinder 13 is movably hinged with the trolley body 1. The two plugging turning plates 51 are respectively detachably installed at the lower ends of the two L-shaped flap plates 5. The plugging turning plates 51 are used to support the ends of the lane slab formwork 2, and a support column 8 is arranged between the lower part of the plugging turning plate 51 and the tunnel floor for supporting the plugging turning plate 51.

[0026] In this embodiment, the thrust mechanism includes a thrust cylinder 6, a U-shaped guide rail 7 and a slider 72. The U-shaped guide rail 7 and the thrust cylinder 6 are both fixedly installed on the upper part of the trolley body 1. The slider 72 is slidably installed in the U-shaped guide rail 7. The upper end of the slider 72 is fixedly connected with the movable support plate 4, and the piston rod of the thrust cylinder 6 is fixedly connected with the slider 72.

[0027] In this embodiment, a plurality of chute openings 32 are uniformly formed at both ends of the fixed support plate 3. Limiting grooves 33 are formed along the length direction on both inner sides of the chute openings 32.

At this time, the assembly work of the lane slab formwork 2 can be carried out;

[0035] After the construction is completed, the screw rod support 14 is removed, and at the same time, the lower end of the L-shaped turning plate 5 is disengaged from the corresponding blocking turning plate 51. The overall lowering of the trolley body 1 is controlled by the lifting oil cylinder 12, and then the diagonal pulling oil cylinder 12 is started. At this time, the L-shaped turning plate 5 can be disengaged from the lane slab formwork 2, and the trolley body 1 is driven by the traveling wheel 11 to move to the next section of the tunnel for construction.
