Description
Technical Field
The utility model relates to a lining cutting platform truck that tunnel construction used, concretely relates to additional component that adapts to curved straight line tunnel and prevents that lining cutting seam from staggering, leaking thick liquid.
Background
In the tunnel construction process, because the sections of the two front and rear end surfaces of the lining trolley have production and processing errors, the sections are not ideal coupling sections, or the two sections are not coupled due to deformation in the construction process, so that the formed two lining end surfaces cannot be well attached to the next plate lining trolley. In order to avoid the phenomenon that the formed secondary lining is squeezed and cracked due to uneven stress, the support is stopped after the lapping section of the lining trolley template of the next plate is partially propped against the formed secondary lining, so that gaps can be generated in the partial sections, and the phenomena of slurry leakage and slab staggering can be caused when the newly-poured secondary lining is poured, thereby not only influencing the appearance quality of concrete, but also influencing the entity quality of construction joints.
