Abstract

The invention discloses a road maintenance crack pouring construction process which is characterized by comprising the following steps: S1, preparation of crack pouring glue: a constructor adds molten crack pouring glue into a placing tank (3) of a crack pouring device, then a heater (7) is started, the heater (7) continuously heats the bottom of the placing tank (3), and the bottom of the placing tank (3) is heated continuously; the contact time of the crack pouring glue at the bottom of the placing tank (3) and heat is prolonged, so that the crack pouring glue in the placing tank (3) is comprehensively and uniformly heated; step S2, crack repairing: after heating is completed, a constructor pushes a crack pouring device to the crack, then an air pump (16) and a gear pump (4) are started, compressed air is provided by the air pump (16), the compressed air is sprayed into the crack through an air spraying head (20) so as to remove impurities in the crack, then crack pouring glue in a placing tank (3) is conveyed into a spraying head (6) through the gear pump (4), and the crack pouring glue is sprayed into the spraying head (6) through the spraying head (6); the crack pouring glue is sprayed to the crack, and the crack is repaired.

Description

technical field [0001] The invention relates to the technical field of highway maintenance, in particular to a construction technology for filling joints for highway maintenance. Background technique [0002] Highway maintenance is the maintenance and maintenance of highways. Maintenance focuses on the maintenance of the whole process from the time it is completed and opened to traffic. Maintenance focuses on repairing the damaged parts. After long-term rolling by vehicles, many cracks will form on the road, and the construction personnel need to Use a seam filling machine to fill the cracks with seam filling glue, so as to repair the cracks, so that the road can be restored to the level, so as to avoid ensuring the safety of driving. [0003] However, the internal temperature distribution of the traditional road maintenance joint filling construction process is uneven, and local heating is prone to occur. The joint filling glue in the incompletely heated area is easy to con...
