Description

Technical Field

[0001] The present application relates to the field of municipal roads, and in particular, to an auxiliary device for laying curb stones for municipal roads. Background Art

[0002] A curb stone refers to a flat curb stone laid between the road surface and the vertical curb stone. After the side curb stones (installed on both sides of the road surface, which are accessories that distinguish the sidewalk, the driving lane or the green belt, and are generally 15 cm higher than the road surface) are laid, the curb stones will be laid beside the side curb stones. When laying the curb stones, it is necessary to level the sand and gravel base beside the side curb stones. Usually, the sand and gravel base is leveled by special vehicles or by workers manually. The manual leveling efficiency is low, and the cost of using special vehicles for leveling is high. Therefore, a sand and gravel leveling device with good practicability is needed.
