Embodiment Construction

[0039] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0040] Such as figure 1 It can be seen that the cracks on the asphalt pavement are in the form of a network before significant frost heaving and grouting have occurred. At this time, in order to prevent water from penetrating into the cracks, surface treatment is required for repair.

[0041] Such as figure 2As shown in -7, this embodiment is an integrated device for antifreeze repair of asphalt pavement, which can repair the network cracked pavement, including a mobile platform 1, which is provided with a repair agent brushing mechanism 2, and the repair agent is applied A ready-mixed stone chips distributing mechanism 3 is arranged behind the brush mechanism 2;

[0042] Restoration agent brushing mechanism 3 includes restoration agent supply structure 4, restoration agent supply structure 4 is connected with restoratio...

Abstract

The invention discloses an asphalt pavement anti-freezing and repairing integrated device which comprises a moving platform, the moving platform is provided with a repairing agent brushing mechanism, and a premixed stone chip laying mechanism is arranged behind the repairing agent brushing mechanism; the repairing agent brushing mechanism comprises a repairing agent supply structure, the repairing agent supply structure communicates with a repairing agent discharging device, a discharging hole is formed in the lower end of the repairing agent discharging device, and a repairing agent brushing roller is arranged below the discharging hole; the discharging hole faces the rear portion of the moving platform, the spraying direction of the discharging hole is completely blocked by the brushing roller, and a repairing agent sprayed out of the discharging hole is located on the front surface of the upper side of the brushing roller. The brushing roller comprises a fixing shaft, the fixing shaft is rotationally connected with a plurality of rolling wheels, and fiber layers are arranged on the wheel faces of the rolling wheels. According to the description of the scheme, the scheme has the beneficial effects that the structure is simple, the design is reasonable, not only is the labor saved, but also the efficiency is improved; in addition, a repairing agent oil material can be uniformly coated on an uneven pavement with cracks.

Description

technical field [0001] The invention relates to the field of asphalt pavement maintenance, in particular to an integrated device for antifreezing and repairing asphalt pavement. Background technique [0002] With the advent of winter, the antifreeze task of the road surface becomes onerous. On the one hand, it is because the asphalt pavement is prone to temperature cracks in winter. There are two types of temperature cracks in the asphalt pavement, one is low-temperature shrinkage cracks or low-temperature cracks for short, and the other is temperature fatigue cracks. Low-temperature cracks mainly occur when the temperature drops sharply, and the asphalt material gradually hardens and begins to shrink. At this time, the bottom of the semi-rigid base will produce tensile stress. When the stress relaxation of the tensile stress asphalt mixture cannot keep up with the temperature stress growth, the stiffness of the mixture increases sharply. Since the asphalt pavement is cons...
