TECHNICAL FIELD

[0002] The paving and tamping device is a road construction equipment combining paving and tamping functions, mainly used to improve paving efficiency and compactness of the road. The patent application No. 202411243294.0 discloses a paving and tamping device for road construction and a paving and tamping method thereof, which comprises: the paving frame comprises an inner plate and an outer plate, and the paving frame is bolted to an external tractor for limiting and fixing the soil shoulder to be paved to a certain size specification. The device is provided with an elastic adjusting paving structure inside, which can adjust the height of the paved soil shoulder according to different construction roads, improve the flexible adjustment effect during road construction, and cooperate with the vertical tamping mechanism during subsequent work to stabilize the compaction of the paved soil shoulder during the operation of the vertical tamping mechanism, prevent the soil from loosening after paving, and set the adjustable slope baffle and inclined tamping mechanism on the side of the vertical tamping mechanism to pave and tamp the slope with different angles, thereby preventing the slope from collapsing during use. The technical solution of the above-mentioned invention mainly aims to adapt to different slopes during paving and tamping, but the conventional paving and tamping device is also difficult to achieve stable and uniform paving and tamping during the paving and tamping of flat roads.
