Drainage template and construction method of permeable pavement

Abstract

The invention relates to a drainage template and a construction method of a permeable pavement. The drainage template comprises a template body with a space inside; drainage columns communicating withthe space are arranged at the top of the template body. The construction method of the permeable pavement comprises the steps of using multiple drainage templates on a basal layer to form a drainagefoundation, wherein water collection spaces are formed between the multiple drainage templates and the basal layer; and then laying bar-mat reinforcements on the drainage foundation; pouring concreteto the drainage foundation to form a concrete layer; and forming multiple holes, which correspondingly communicate with drainage openings in the top end of each row of drainage column, in the top surface of the concrete layer so as to form a porous permeable pavement with water reservoir so that the porous permeable pavement can be applied to a surface pavement to rapidly guiding rainwater to enter the water collection space in the bottom of the drainage foundation through the drainage openings. Problems that the water permeability of an existing concrete layer surface pavement is poor and rainwater is hard to be guided into a soil layer on the downside through the concrete layer surface pavement.

Description

technical field [0001] The invention relates to a permeable pavement construction method with the function of reducing surface runoff and a drainage template used in the construction method. Background technique [0002] Due to abnormal climate change, severe floods have occurred in many cities in recent years, causing damage to people's lives and property. In addition, due to urban floods, runoff pollution, loss of rainwater resources, aging drainage systems and backward construction, the deterioration of the water environment and ecological environment has become an important factor hindering the sustainable development of cities. [0003] As mentioned above, the problem of urban flooding is mainly due to the continuous development of urban land, resulting in more and more impermeable pavements, and the runoff of rainwater on urban roads is becoming more and more serious. In particular, modern urban construction is mostly composed of concrete, asphalt, Driveways, walkways...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a construction method for drainage formwork and permeable pavement, which solves the problem that the current surface pavement has poor water permeability, and there is no space for storing rainwater, so it is difficult to quickly guide rainwater through the surface pavement to the bottom. The problem of reducing surface runoff in the soil layer
