Portable hand-push joint bonding device

Technical Field

The utility model relates to the technical field of pavement groove filling tools, in particular to a portable hand-push joint bonding device.

Background

Asphalt pavement refers to various types of pavement paved by incorporating road asphalt materials into mineral materials. The asphalt binder improves the capability of paving granules to resist damage to the road surface caused by driving and natural factors, so that the road surface is flat, less in dust, waterproof and durable. Accordingly, asphalt pavement is one of the most widely used advanced pavements in road construction.

The crack is one of main diseases of the asphalt pavement, and various technical means are adopted to seal the pavement crack, prevent water from penetrating into the pavement structure, and are widely regarded as effective means for slowing down the occurrence of pavement diseases and prolonging the service life of the pavement internationally. The crack is usually repaired by filling or pouring the crack, wherein the crack is not expanded by the filling technology, and the crack is directly filled by the filling material, so that the use effect is generally poor; the slotting and seam expanding technology firstly carries out slotting and seam expanding, then adopts sealant to fill the seam, and has relatively good use effect, but the slotting and seam expanding construction efficiency is low, secondary diseases can be caused by slotting, and the pollution such as noise, dust and the like can not be avoided in the construction process.
