Preposed press-wheel device of road roller, and operation method of preposed press-wheel device
The invention discloses a preposed press-wheel device of a road roller, and an operation method of the preposed press-wheel device. The press-wheel device comprises a wheel body I, a wheel body II and press-wheel frames, wherein the wheel body I is positioned in front of the wheel body II; the press-wheel frames are respectively positioned on two sides of the wheel body I and the wheel body II; the wheel body I and the wheel body II are respectively prepared from 30% of gravel, 10% of limestone, 15% of cement, 10% of inorganic adhesive materials, 1% of hydroxypropyl methyl cellulose, 1% of heavy calcium carbonate, 1% of polyethylene fibers, 2% of rubber powder, 5% of kaolin powder, 5% of water, 8% of aggregate, and 12% of asphalt; the grain diameter of the gravel is greater than 1.7mm; the cement is pozzolana cement. The press-wheel device of the road roller is novel in structure. Through the adoption of the press-wheel device, working staff in an operation room can learn about the leveling conditions of road surfaces in real time, and agglomeration and dirt cannot be generated, so that the leveling degree is high.
