Prefabricated concrete road system and construction method

Abstract

The invention relates to the technical field of road construction, and provides a prefabricated concrete road system, which includes base layer curb stones; the curb stones are composed of horizontal stones and vertical edge stones; the area surrounded by the horizontal stones is paved with asphalt surface layer, Concrete pavement base and graded gravel layer; the concrete pavement base is spliced ​​by several concrete slabs; the lower part of the gap between adjacent concrete slabs is filled with elastic materials, and the upper part is filled with expansion waterstop strips. The quality of the prefabricated concrete road system is easy to guarantee, easy to install, and easy to replace after being damaged. Also provided is a construction method, which includes filling the foundation layer; paving curb stones and rainwater wells; paving the graded crushed stone layer; paving the concrete pavement base; filling the joints of the concrete slabs with elastic materials; The curbstones and concrete slabs in this construction method are all processed in the factory, the site construction efficiency is high, and the later maintenance period is short.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a prefabricated concrete road system and a construction method. Background technique [0002] At present, cast-in-place concrete pavement systems are generally used for roads. Due to the influence of natural environmental factors and maintenance conditions, the quality of cast-in-place concrete is not easy to guarantee, and the construction period is long. In addition, after the concrete pavement has been used for several years, the pavement is prone to damage, cracking, and subsidence. Every repair needs to destroy the original damaged road, which is easy to generate a lot of construction waste, and seriously affects the traffic of vehicles, causing huge economic losses. [0003] In engineering construction, it is often necessary to lay some temporary construction roads, such as temporary sidewalks during urban subway construction. These temporary roads need to be dism...

AI Technical Summary

Problems solved by technology

[0002] At present, the road generally adopts cast-in-place concrete pavement system, and the cast-in-place concrete is affected by natural environmental factors and maintenance conditions, its quality is not easy to guarantee, and the construction period is long

In addition, after the concrete pavement has been used for several years, the pavement is prone to damage, cracking, and subsidence. Every time it is repaired, the original damaged road needs to be destroyed again, which is prone to generate a lot of construction waste, and seriously affects the traffic of vehicles, causing huge economic losses.

[0003] In engineering construction, it is often necessary to lay some temporary construction roads, such as temporary sidewalks during urban subway construction. These temporary roads need to be dismantled after the use function is completed, and a large amount of construction waste will be generated during dismantling, resulting in waste of resources. also pollute the surrounding environment
