Water drainage and storage concrete pavement structure and construction method

Abstract

The invention provides a water drainage and storage concrete pavement structure, which comprises an embankment, a semi-rigid base layer, a bonded waterproof layer, a lower assembly board and an upperassembly board in sequence from bottom to top, wherein a flexible waterproof layer and a plate drainage board are arranged at a lateral joint of the lower assembly board and the upper assembly board,end plates are arranged on the outer side of the lower assembly board, the end plates and the lower assembly board are integrally prefabricated, the top surface elevation is the same as the elevationof an outer side slow track, and prefabricated water tanks are arranged at the lower side of the slow track and the outer side of the lower assembly board. According to the invention, the upper assembly board is arranged between the end plates on the outer side of the lower assembly board, and the flexible waterproof layer and the plate drainage board are arranged at the lateral joint of the upperassembly board and the lower assembly board, so that not only is the lateral movement of the upper assembly board limited, but also the influence of temperature stress on the single-layer board can be reduced, and the interlayer movement of a water body can be achieved. The prefabricated water tank is arranged on the outer side of the lower assembly board and communicated with a built-in drain pipe, so that rainwater on a road surface can be stored and reused.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a drainage and storage concrete 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, save project cost and road performance indicators under the premise of ensuring the quality of project construction is often the focus of engineering and academic circles. At the same time, as the road is an important collection area of ​​rainwater, how to improve the drainage performance and durability of the pavement structure has become an important factor restricting the construction of road engineering. [0003] At present, concrete pavement construction usually requires on-site reinforcement and concrete pouring. Although the construction technology and structure have the characteristics of simple on-site construction technology an...

AI Technical Summary

Problems solved by technology

Although this kind of pavement can alleviate the pavement water to a certain extent and has good anti-skid performance, the flatness and durability of the pavement surface layer are poor, and the construction period is long

[0004] In summary, although the existing concrete pavement structure and construction methods have achieved good results under suitable working conditions, there is still room for improvement in the performance of the pavement, the improvement of construction efficiency, and the improvement of drainage and storage performance.
