Self-propelled tunnel inverted arch trestle waterproof and drainage operation platform

The utility model relates to a self-propelled tunnel inverted arch trestle waterproof and drainage operation platform which comprises a trestle main beam and trestle walking supporting legs connected with the trestle main beam through sliding rails, one side of each trestle walking supporting leg is connected with an operation platform in a rotating mode, and a hydraulic oil cylinder is connected between each trestle walking supporting leg and the operation platform. The hydraulic oil cylinder stretches and retracts to drive the working platform to be folded. The foldable waterproof and drainage operation platform is arranged on one side of the front supporting leg of the self-propelled inverted arch trestle, so that the operation platform not only can realize radial telescopic folding of a tunnel, but also can realize deep sliding of the tunnel along with the front supporting leg of the inverted arch trestle, and the problem of position conflict between the operation platform and an inverted arch template is
