Highway road surface basement floating pulp cleaning machine

Abstract

This invention discloses a kind of road surface base laitance descaling machine. It includes the shell. The lower shell has open. On the shell there set the gear change mechanism which connects with the pulling mechanical power export and the suspension mechanism which connects with the pulling mechanism. In the shell there is the revolution axis which connects with the gear change mechanism power. On the revolution axis there sets the steel wire brush disk, it rotates with the revolution axis .The stated steel wire brush disk has many sequent superposition groups to form it. And the stated revolution axis is divided into two connecting segments. This invention let the pulling mechanism push the semirigid stable base surface which edge needs disposing to move. And it lets the steel wire brush disk has reverse rotation which is relative to the pulling mechanism heading position. It cleans up the semirigid stable base surface's laitance and has a galling. It clears the surface to the shape of 'water brushing rock' and effectively increases the appetency between bitumen layer and semirigid stable base surface layer. It improves the felt effect. Its structure is simple and the working efficiency is high. It largely lowers the worker's labor strength. Its social economic efficiency is prominent.

Description

technical field [0001] The invention relates to a machine for building and repairing roads, airports, and squares, in particular to a laitance cleaning machine for road surface bases. Background technique [0002] At present, in the process of highway construction and maintenance, a semi-rigid and stable base layer composed of gravel, lime, fly ash, cement, crushed (gravel) stone, sand, etc. Asphalt pavement. There are certain defects in this construction method, that is, the upper surface of the semi-rigid stable base has low affinity with the asphalt surface layer, and the bonding effect is poor, resulting in diseases such as "bone-returning" and "water-permeable grout" on the pavement, resulting in road damage. Early damage shortens service life. The first reason is that the surface of the semi-rigid stable base has laitance and sticks to the upper surface of the aggregate; the second is that the surface of the semi-rigid stable base composed of powder is relatively smo...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that during the construction of the road, due to the presence of laitance on the surface of the semi-rigid and stable base and the smooth surface, the affinity between the asphalt layer and the semi-rigid and stable base is reduced, and the bonding effect is poor. According to the current situation of area treatment, a laitance cleaning machine for highway pavement base is provided to effectively clean the surface of semi-rigid and stable base, and to meet the construction requirements of effective bonding between asphalt layer and semi-rigid and stable base
