Abstract

The invention discloses a water-bound gravel paving device for road construction. Water pump, gravel rolling control box, the mechanical arm circuit control device is equipped with a pressure sensing tube, an air pressure transition tube, a water pressure control glass tube, a first energized spring, a first conductive floating ball, a first energized guide rod, a second 1. Connecting wires and connecting wire fixing rings, so that when the equipment is in use, pressure devices can be added to the water tanks on both sides, so that the range and range of sprinkling can be controlled by strong pressure during sprinkling, and the range of sprinkling can be enlarged. The work is done quickly, while the water-bound gravel is compacted by the crushing hammer to make the pavement stronger.

Description

technical field [0001] The invention relates to a water-bound gravel paving device for road construction, which belongs to the field of water-bound gravel paving devices. Background technique [0002] Water knot, which relies on the crushed stone powder slurry when the gravel is sprinkled and rolled, as the bonding material, so the stone used should be limestone or dolomite, and the stone must be compacted on a grade 3 or above road surface. The thickness is generally 8 to 16 cm. During construction, the main layer of stones should be paved according to the thickness of the road surface with a loose paving coefficient of 1.3 to 1.4, sprinkled with a small amount of water, pressed until it is basically stable, then sprinkled with a large amount of water, fully compacted, then sprinkled with caulking stones, sprinkled with water and rolled, and then rolled Sprinkle the cover material evenly, and press it until no wheel marks appear on the surface, and continue to sprinkle wate...
