Cement pavement structure and construction method thereof

Abstract

The invention provides a cement pavement structure and a construction method thereof. The cement pavement structure comprises a base layer, a connecting reinforced layer, a lower assembling plate, a bonding water-resisting layer, a heat-preservation and insulation layer and an upper assembling plate from bottom to top in sequence. According to the cement pavement structure, the connection strengthbetween the upper assembling plate and the lower assembling plate can be effectively enhanced by arranging the lower assembling plate and the upper assembling plate, so that horizontal movement of the upper assembling plate is prevented, the influence of warping deformation, differential settlement deformation of the lower assembling plate on the upper assembling plate is reduced, at the same time, rainwater which seeps downwards can further be removed in time to prevent the road structure from occurring water-induced damage, the integrity of the upper assembling plate is enhanced, and the upper assembling plate is prevented from occurring plate edge or plate angle damage; and by arranging the bonding water-resisting layer and the heat-preservation and insulation layer between the upper assembling plate and the lower assembling plate, a channel for upper water body to seep downwards can be effectively blocked, heat transfer between layers is reduced, and the influence of temperature stress on the pavement structure is reduced.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a cement pavement structure and a construction method. Background technique [0002] In the construction and construction process of urban roads and highways in my country, how to effectively shorten the construction period and save project cost under the premise of ensuring the quality of project construction is often the focus of engineering and academic circles. Concrete pavement construction usually requires on-site reinforcement and concrete pouring. The on-site construction process is simple, and the requirements for construction machinery are low, and good engineering construction results have been achieved under suitable working conditions. [0003] For example, the Chinese invention patent application with the publication number CN 105603843A discloses an assembled reinforced concrete prefabricated road slab and its construction method. The prefabricated road slab include...

AI Technical Summary

Problems solved by technology

[0004] The pavement structure is a single-layer cement pavement slab, and it is difficult to effectively reduce the thickness of the cement pavement slab. The connection strength between the metal edge protection and the pavement slab is low. It is difficult to eliminate the influence of temperature stress on the performance of the pavement structure as a whole, and it is difficult to realize the overall force of the structure.

In addition, cast-in-place concrete often requires a long maintenance period, and has high requirements for on-site construction quality control, which is prone to problems such as insufficient pavement thickness and low strength, and further improvement in pavement performance and construction efficiency
