Highway subgrade maintenance pavement crack pouring device

Abstract

The invention discloses a highway subgrade maintenance pavement crack pouring device which comprises a base and a stone dust collecting cavity arranged at the front end of the bottom of the base, wherein two damping adjusting rods are rotationally installed at the rear end of the interior of the stone dust collecting cavity, and a first rotating roller is installed between the lower ends of the damping adjusting rods; a plurality of groups of first brushes are arranged outside the first rotating roller; a protective shell which is arranged on the stone dust collecting cavity, wherein a dust collecting cover is fixedly mounted at the upper end of one side in the stone dust collecting cavity; a positioning groove which is formed in the rear end of the stone dust collecting cavity; and a stirring barrel which is arranged in the middle of the upper end of the base, wherein a leveling device is installed outside the glue injection head on the glue injection device, and telescopic plates are installed on the two sides of the interior of the leveling device in a sliding mode. In the repairing process of the pavement gap, the pouring sealant can be accurately and compactly injected into the pavement gap along the notch direction of the gap, and the gap can be cleaned.

Description

technical field [0001] The invention relates to the technical field of highway maintenance, in particular to a road surface joint filling device for highway subgrade maintenance. Background technique [0002] The subgrade of the highway refers to the pavement foundation of the highway, which is a geotechnical structure formed after excavation or filling. The main function of the roadbed is to provide the necessary conditions for pavement laying and driving operation, and to bear the static and dynamic loads of rolling stock or road surface and traffic loads, and at the same time transfer and spread the load to the depth of the foundation. Urban roads and highways paved with asphalt Long-term use or due to geography and heavy vehicles, the pavement often has more irregular cracks. Asphalt pavement cracks are one of the early major diseases that are most likely to cause other lesions on asphalt pavement under heavy-duty traffic. Asphalt pavement cracks not only destroy The co...

Problems solved by technology

[0004] However, there are some problems in the use of the existing seam filling device: 1. During the process of injecting the seam glue into the gap, due to the large temperature difference between the seam body and the seam glue, under the action of thermal expansion and cold action It is easy to generate air bubbles and affect the effect of filling joints; 2. During the process of joint filling, the dust and residual stones in the notch have a great influence on the adhesion performance of the potting compound, so it does not meet the existing needs. For this, we propose a road Subgrade maintenance pavement filling device
