Concrete vibration device and vibration method for constructional engineering

The concrete vibration device comprises vehicle frames, a vehicle plate and a vibration rod, concrete is vibrated through the vibration rod, the two vehicle frames are arranged below the vehicle plate, the lower portion of each vehicle frame is connected with two universal wheels, and a two-stage rail adjusting assembly is arranged above each vehicle frame; the two-stage rail adjusting assembly is fixedly connected to the guide rail frame, the guide rail frame can be subjected to height adjustment, the sweeping board is slidably connected to the two-stage rail adjusting assembly, the vibrating bar is slidably connected into the sweeping board, and the buffering assembly is arranged in the middle of the vibrating bar to buffer the influence on the sweeping board in the concrete vibrating process. The upper end of the vibration rod is connected with a quick-inserting and slow-pulling mechanism through a damping assembly, the quick-inserting and slow-pulling mechanism is installed on the vehicle plate, and quick
