Water-bound macadam road paving device for road construction

Abstract

The invention discloses a water-bound macadam road paving device for road construction. The water-bound macadam road paving device for road construction structurally comprises a water sprinkling and rolling vehicle body, a water sprinkling and rolling vehicle head, a first water sprinkling water tank, a second water sprinkling water tank, an external driving motor, a control water suction pump anda macadam rolling control box, wherein a mechanical arm circuit control device is provided with a pressure sensing tube, an air pressure transition guide pipe, a water pressure control glass tube, afirst energizing spring, a first conductive floating ball, a first energizing guide rod, a first connecting conductor and a connecting conductor fixing ring. The water-bound macadam road paving devicehas the advantages that in the use process, by arranging pressure devices in the water tanks at both sides, the water sprinkling range and scope can be controlled by pressure during water sprinkling,the water sprinkling scope is increased, and the water sprinkling can be quickly completed; the water-bound macadam is rolled by a macadam rolling hammer, so that the paving is firmer.

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...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a water-bound gravel paving device for road construction to solve the problem of watering and rolling after the prior art is used, while the traditional road paving The equipment cannot fully meet the paving requirements, the sprinkling of water is uneven, and the paving efficiency is low, which will affect the progress of road construction
