Concrete preassembled road high in rupture strength

Abstract

The invention discloses a concrete preassembled road high in rupture strength. The concrete preassembled road comprises four concrete precast slabs; the two sides of each concrete precast slab are provided with holes used for placing steel strands; adjacent concrete precast slabs are connected via the steel strands; the diameter of the steel strand is 15.50mm; the four sides of each concrete precast slab are provided with the holes used for placing the steel strands, and adjacent concrete precast slabs are connected via the steel strands; one road surface unit is formed from the four concrete precast slabs via the steel strands and steel connecting plates arranged on the outsides of the concrete precast slabs; connecting key structures are arranged between adjacent concrete precast slabs; each connecting key structure comprises a shearing-resistant convex key and a shearing-resistant concave key matching with each other. The concrete preassembled road is convenient for transportation, and rapid and convenient for installation; road slabs can be divided into a plurality of kinds and types according to the ratio of the short edges to the long edges; and the plurality of positioning shearing-resistant connecting keys are arranged on the joint interfaces of the precast slabs so as to ensure that rupture or breakage of the road slabs is not caused under repeated action of overload vehicles.

Description

technical field [0001] The invention relates to a concrete prefabricated road with high flexural strength. Background technique [0002] my country's economy is currently in a period of rapid development, and a large number of roads of various grades are built every year, a large part of which is concrete roads. At present, domestic concrete roads mainly adopt cast-in-place concrete construction technology, which requires on-site support formwork, binding steel bars, pouring concrete, concrete curing and other construction processes. The disadvantages of the cast-in-place concrete production process are mainly as follows: [0003] The production efficiency is low, a large amount of human resources are consumed, and the construction period is long. The on-site construction mainly adopts manual operation, and the product quality is not easy to guarantee. Great environmental pollution, on-site pouring of concrete produces noise, sewage, waste and other environmental pollutio...

AI Technical Summary

Problems solved by technology

[0003] Low production efficiency, consume a lot of human resources, long construction period

On-site construction mainly adopts manual work, and product quality is not easy to guarantee

Great environmental pollution, on-site concrete pouring produces noise, sewage, waste and other environmental pollution

When the pavement is demolished or abandoned, the pavement materials will form construction waste, which cannot be reused, resulting in a waste of resources

Construction is greatly affected by the climate

Rainy and cold seasons are unfavorable for construction, resulting in longer seasonal downtime

Therefore, the above shortcomings of cast-in-place concrete roads have become a bottleneck restricting the industrialization of concrete roads
