Asphalt tank suitable for asphalt fissure cementation of road maintenance road surface and fissure cementation method

Abstract

The invention provides an asphalt tank suitable for asphalt fissure cementation of a road maintenance road surface and a fissure cementation method. The asphalt tank comprises a fixed bottom plate, universal bottom wheels, a mounting frame, a storage battery, a push rod, an asphalt heating protection cover structure, a power switch, asphalt standby storage and mixing box structures, an asphalt storage tank, a suction pump, an L-shaped discharging pipe, an L-shaped extraction pipe, a transverse fixed frame, a longitudinal locating hole, an adjustable sweeping frame structure, an auxiliary presswheel structure, a fissure filling pipe and a discharging valve. The universal bottom wheels are mounted at the four corners of the lower portion of the fixed bottom plate in a bolted manner. According to the asphalt tank, through the arrangement of sweeping brushes and a rotary disc, fissures on the road surface can be swept easily; and through the arrangement of an upper fixed nut and a lower fixed nut of an external thread locating rod, the positions of the upper fixed nut and the lower fixed nut on the external thread locating rod can be conveniently adjusted according to use needs duringuse, and then the height of the sweeping frame can be conveniently adjusted.

Description

technical field [0001] The invention belongs to the technical field of road surface maintenance, and in particular relates to an asphalt tank and a joint filling method suitable for asphalt filling joints on highway maintenance road surfaces. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, r...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an asphalt tank and a joint filling method suitable for asphalt filling joints on road maintenance pavement, so as to solve the inconvenient cleaning of the cracks and inconvenient adjustment of the existing asphalt tanks for asphalt joint filling. The height of the cleaning frame does not have the ability to flatten the asphalt after filling the joints, does not have the effect of stirring and mixing the asphalt and has poor heating effect on the asphalt
