A row of quick pavement breaking device

Abstract

The application relates to the field of road construction, in particular to a row type rapid road surface breaking device. All the first ground drilling bits and all the second ground drilling bits form a row type distribution structure, the second ground drilling bit uses a small-diameter drill bit, is drilled into the road surface first to perform pre-splitting treatment, and a plurality of crack structures are drilled on the road surface, the first ground drilling bit uses a large-diameter drill bit, is drilled into the road surface later, and performs complete breaking treatment on the basis of the pre-formed crack structure, realizes rapid breaking work of a large-width range on the road surface, and can also switch the second ground drilling bit and the first ground drilling bit to a front-and-back staggered distribution structure state to perform rapid breaking work on the road surface in a large-area range. The application solves the technical problems of a small working width of a traditional ground drilling machine, incapability of meeting the demand of large-area road surface treatment, and influence on road surface renovation and maintenance construction efficiency.
