Description

Technical Field

[0001] The utility model relates to the technical field of pavement grouting, in particular to a vehicle-mounted semi-flexible pavement grouting device. Background Art

[0002] At present, rutting disease has become one of the main forms of asphalt pavement disease. In order to prevent and control rutting disease on asphalt pavements, a semi-flexible composite pavement anti-rutting technology has gradually been applied. Its principle is to first lay a large-pore asphalt pavement with a void ratio of 20% to 30% on the road. After its surface temperature drops, a slurry material is poured into the large-pore asphalt mixture. After hardening, the slurry has greater rigidity, and forms a "rigid and flexible" semi-flexible composite pavement with the large-pore asphalt mixture, thereby effectively resisting rutting disease on asphalt pavement.

[0003] During the construction of semi-flexible pavement, a set of efficient grouting and grouting equipment is a prerequisite for the smooth progress of the project. However, the existing grouting and grouting equipment still has certain shortcomings in terms of construction efficiency and convenience. For example, the patent with application number 201921867244.4 discloses a direct-throw semi-flexible pavement slurry making equipment, including a feeding device, a stirring device, a power device and a water storage device. The equipment is small as a whole and easy to move, but its discharge port is at the bottom of the equipment. When the slurry is transported to a long distance, additional manpower is required, and the second cylinder of slurry can only be produced after one cylinder of slurry is used up. It is difficult to achieve continuous discharge and the efficiency is low; for example, the patent with application number 201510713520.1 discloses a grouting equipment suitable for the construction of semi-flexible pavements, including a frame, a slurry storage box, a vacuum pump, and a sealing gasket. The grouting equipment improves the grouting process to a certain extent and reduces the design requirements of the grouting material. However, during the use of the equipment, slurry production cannot be carried out, and the pre-prepared slurry needs to be additionally introduced into the slurry storage box, and there is no stirring device in the slurry storage box. When the slurry is consumed slowly in the slurry storage box, segregation is likely to occur, which is not conducive to the quality assurance of the semi-flexible pavement. The above-mentioned existing semi-flexible pavement construction equipment is difficult to achieve efficient and convenient slurry making and grouting. In order to change this situation, this application proposes a vehicle-mounted semi-flexible pavement grouting equipment, which can realize self-service slurry making and all-round grouting, which can save manpower and ensure the uniformity of the slurry, and has important practical significance.
