The invention discloses a maintenance construction method of an asphalt road surface solid permeability wearing layer. The construction method includes the following steps that the spreading amount ofa solid permeability agent is surveyed; a road surface is cleaned; the road surface is pre-processed; the solid permeability agent is sprayed; a wearing layer is spread; manual trimming is carried out; preliminary maintenance is carried out. According to the maintenance construction method, the solid permeability agent is demulsified immediately after being atomized or smeared on the original road surface, heavy cycloparaffin distilled oil rapidly infiltrates to restore old asphalt performance, early diseases of the original asphalt road surface are repaired, and meanwhile a matrix asphalt and tackifier mixture is left on the road surface to form a binding layer. A solid permeability layer is formed by the repaired original asphalt road surface and the binding layer. The maintenance construction method is high in construction speed and efficiency.

The invention discloses a drying device for printed products, which comprises a seat box plate, a partition plate is fixedly connected to the top of the seat box plate, an air hole is opened in the middle of the top of the partition plate, and the top of the partition plate is located at A heating mechanism is movably connected to the outer side of the airflow hole, and the middle and lower positions of the inner surface of the heating mechanism are movably connected to a distribution shelf, and the top of the distribution shelf is movably connected to an airflow fan, and the top of the partition plate is movably connected to a Conveying rollers, the top of the partition plate is located outside the heating mechanism and between the conveying rollers are provided air hole slots. The present invention relates to the field of printing technology. By placing the printed product vertically and using the airflow to continuously blow upwards, the wind resistance generated by the wind will inhibit the weight of the printing dye from falling, preventing the printed dye from penetrating or dripping to the surrounding area, and reducing its damage to the quality of its own products , to ensure the safety of the surrounding environment.

The invention belongs to the field of structural design of stirring equipment, and in particular relates to a composite bearing deflection limiting device for a stirring shaft. The composite bearing deflection limiting device comprises a bearing block and a support frame, wherein the bearing block comprises an outer ring sleeve directly sleeving a shaft body of the stirring shaft, and a hole wall of the outer ring sleeve is spaced from the shaft body of the stirring shaft; a plurality of roll shaft parts are annularly arranged on the hole wall of the outer ring sleeve along the axial line of the hole wall, each roll shaft part comprises a stator shaft and a rotating sleeve, and the axial line of the outer ring sleeve, the axial line of a stator shaft and an ideal axial line of the stirring shaft are coaxially and vertically arranged; a section, matched with the rotating sleeve, of the stator shaft has a spindle-shaped structure, and the rotating sleeve correspondingly has a sleeve structure with a concave spherical inner cavity; on the axial cross section passing through the axial line of the stator shaft, the diameters of generatrixes of the stator shaft and the rotating sleeve at sections matched with each other are consistent and the circle centers are positioned on the same horizontal plane, and the diameter of the generatrix at a hole cavity of the rotating shaft is greater than that of the generatrix of the stator shaft. By adopting the composite bearing deflection limiting device provided by the invention, the effect of fixing the shaft body of the stirring shaft within an allowed deflection quantity range can be realized.
