Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to a road construction pavement splicing and repairing device. Background Art

[0002] When cracks appear on various types of roads such as urban roads, expressways and trunk roads, airport runways, parking lots, industrial park roads, bridges and tunnels, and rural roads after long-term use, they are generally cleaned with fans and brushes first, and then repaired with asphalt.

[0003] Most of the existing road asphalt repairs are done manually with a hand-held pot for grouting. However, manual labor requires bending over for a long time, which is relatively labor-intensive and has the problem of poor grouting quality due to hand shaking. An existing Chinese utility model patent (CN 221441259 U) discloses an asphalt road repair device. When in use, the worker pours asphalt or grouting glue into a grouting oil pot, pushes the repair device to the upper side of the road crack, aligns the feed port with the gap, and presses the gate handle. The gate handle can control the opening and closing of the baffle through the pull wire to control the discharge of the feed port. The worker pushes the push rod to make the feed port on the lower side move along the gap, and the crack is repaired. Loosening the gate spring can make the baffle rebound and reset, stopping the discharge of the feed port.

[0004] The above method can avoid workers bending over when repairing the road surface, but the shape and size of the feed opening are fixed, and the feed opening cannot extend into cracks of different sizes. When repairing the road surface in low temperature weather and windy weather, the feed opening does not penetrate deep into the cracks, which will increase the height of the asphalt falling. Strong winds will also affect the falling trajectory of the asphalt, making it difficult for the asphalt to fall into the cracks, increasing the difficulty of road repair and wasting asphalt. In addition, the temperature of the asphalt will decrease during the falling process, and its fluidity will deteriorate, so there is a situation where the asphalt cannot flow to every corner of the crack.
