The water in the guide pipe 14 is sprayed out through the atomizing nozzle 15. The atomized water is sprayed on the concrete, which makes the concrete more moist and allows the concrete to contact the pebbles more closely. Then the water supply tank 16 is closed and the atomizing nozzle 15 stops spraying water. In this way, the pebbles can be paved more stably on the concrete, thereby further improving the stabilization effect.
