Problems solved by technology

At present, there are mainly two ways to spread quartz sand in the construction process of sand mist seal layer. One is to pre-mix quartz sand and emulsified asphalt in a mixing tank at one time, and then spread. The amount of emulsified asphalt is large, and the mixing degree of the two is not easy to control. The asphalt storage tank on the sprinkler used in this construction method needs to be equipped with an agitator; another method is to artificially sprinkle quartz sand on the road surface in advance. , and then spray emulsified asphalt, because the spraying of quartz sand and emulsified asphalt cannot be synchronized, so the quartz sand cannot be embedded in the asphalt surface, and the anti-skid purpose cannot be achieved, and there is also uneven spreading. None of these methods can deal with special circumstances (sudden rain or other causes the construction had to be suspended), which will lead to waste of sand mist sealant materials

Abstract

The invention relates to the technical field of road fog sealing layer maintenance equipment, specifically to spraying equipment of a sand containing fog sealing layer and a spraying vehicle. The spraying equipment of the sand containing fog sealing layer comprises a first storage device, a second storage device, a stirring device, a spraying device and a control device; in the using process, a composite binder is added to the first storage device, quartz sand is added to the second storage device, the composite binder and the quartz sand can be stirred and sprayed at any time according to field construction situations to be beneficial for sufficient utilization of the quartz sand and the composite binder; instant stirring is effectively realized so that the quartz sand is preferably embedded into the asphalt surface to achieve a good anti-skid purpose; and moreover, the spraying equipment of sand containing fog sealing layer is also beneficial for uniformly spraying; and even though the spraying is suddenly interrupted, the waste of a sand containing fog sealing layer material cannot be caused.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment for road fog seals, in particular to a spraying device and a spraying vehicle containing sand and mist seals. Background technique [0002] With the development of my country's transportation industry, the increase of traffic volume and overloaded transportation, after a long period of use on asphalt concrete roads, the road surface will appear rutting, wrapping, cracking, smooth surface and other diseases. Many diseases of asphalt pavement are Caused by water seepage on the surface. At present, road pavement maintenance generally uses sand mist seal layer spraying equipment to spray mist seal layer materials to form a layer of modified asphalt adhesive layer on the road surface, restore the adhesion of road surface asphalt, fill small cracks and gaps, and prevent road surface water. Infiltration to prevent further aging of the pavement. At present, there are mainly two ways to spre...
