[0003] For example, in Chinese patent document CN222499935U, a road construction joint device includes a bottom plate, on which a joint mechanism is installed. The joint mechanism includes a storage tank, a connecting pipe is connected below the storage tank, the connecting pipe is connected to a filling nozzle, a rolling roller is arranged behind the filling nozzle, the rolling roller is movably installed between two mounting plates, the mounting plates are connected to a support plate, the support plate is fixedly connected to a connecting plate, the connecting plate is fixedly connected to a sliding rod, the sliding rod passes through the bottom plate and is fixedly connected to a limiting block, a spring is installed between the limiting block and the bottom plate, the spring is sleeved outside the sliding rod, and both ends of the spring are fixedly connected to the limiting block and the bottom plate respectively. When pre-installed, the spring is in a stretched state, providing a road construction joint device that can actively perform rolling and paving operations, saving time and effort, and having high work efficiency.
