Assembling type inclined slow-adhesion pre-stressed concrete road surface structure

Abstract

The invention discloses an assembling type inclined slow-adhesion pre-stressed concrete road surface structure. The assembling type inclined slow-adhesion pre-stressed concrete road surface structure comprises a rubber waterstop, a CA mortar connection layer and an anchor head; the structure is formed by the mutual connection of a plurality of prefabricated pre-stressed concrete road surface plates; a plurality of pore channel holes and grouting holes are formed in the adapted positions of each side face and the upper end face of the prefabricated pre-stressed concrete road surface plates; and slow-adhesion pre-stressed steel bars are inserted into a steel bar pore channel through the pore channel holes and cement mortar is filled from the grouting holes. The structure disclosed by the invention is prefabricated in a factory and is positioned and mounted in a construction site; concrete does not need to be cast on site; the structure is convenient and rapid to mount, the influences caused by the environment are slight, the production efficiency is high and the quality is good; and a lot of manpower resources are saved. A road surface does not need to be provided with a transverse seam so that a damage phenomenon caused by the seam on a common cement concrete road surface is solved; the road surface repairing and maintenance cost is reduced; the use performance of the road surface is improved, the noise of the road surface is lowered and the driving comfort is improved; and the service life of the cement concrete road surface is prolonged.

Description

technical field [0001] The invention relates to a concrete pavement structure, in particular to an assembled oblique slow bonding prestressed concrete pavement structure suitable for road engineering. Background technique [0002] In the ordinary cement concrete pavement structure, because the concrete material has the characteristics of high rigidity and high brittleness, it is easy to fracture and damage. At the same time, due to thermal expansion and contraction of ordinary cement concrete pavement, many transverse joints need to be built. Under the action of traffic load, the joints are easy to cause water seepage, mud pumping, wrong platform, void at the bottom of the slab, uneven subsidence and other diseases; at the same time , a large amount of maintenance work is required for the joints, which not only increases the complexity of the construction, but also reduces the driving comfort; [0003] The prestressed concrete pavement is prestressed by tensioning steel bar...

AI Technical Summary

Problems solved by technology

Therefore, it is difficult for the longitudinal prestressing technology to adapt to large-area paving of concrete pavements from the perspective of theory and construction technology.

In addition, prestressed concrete pavement is usually poured on site, the construction quality cannot be effectively guaranteed, it is difficult to realize automatic and mechanized construction, and the construction period is long
