Embodiment Construction

[0026] figure 1 with figure 2 Shows a specific embodiment of the road drainage system of the present invention, a road drainage system, such as figure 1 As shown, it includes a pavement drainage part and a roadside drainage part, and the pavement drainage part is as follows from bottom to top: a base layer, a waterproof layer, and a permeable layer. The base layer is the soil base layer 7; the waterproof layer is the air-permeable anti-seepage sand layer 6; the above-mentioned air-permeable anti-seepage sand layer 6 is provided with a protective geotextile layer 5; the permeable layer includes: a permeable concrete layer 4 , fine gravel layer 3, leveling layer that is graded gravel layer 2, and ecological sand surface layer 1. A pavement drainage ditch is arranged above the waterproof layer. A pavement drainage groove is arranged above the waterproof layer, which is a municipal diversion channel under the permeable road curb. The roadside drainage part includes permeable ...

Abstract

The invention discloses a road drainage system comprising a road surface drainage part and a road side drainage part, wherein the road surface drainage part is orderly provided with a base layer, a waterproof layer and a non-watertight layer from bottom to top; the upper part of the waterproof layer is provided with a road surface drainage groove; the road side drainage part comprises non-watertight curbstones and road side drainage grooves; the non-watertight curbstones are arranged on both sides of a road and adjacent to the road surface drainage part; the road side drainage grooves are arranged under the non-watertight curbstones; the non-watertight curbstone comprises a non-watertight surface layer and a non-watertight strengthening layer; the non-watertight surface layer contains non-watertight material; the non-watertight strengthening layer is adjacent to the inner surface of the non-watertight surface layer and a cavity is arranged in the non-watertight strengthening layer. The road drainage system is provided with the road surface drainage part and the road side drainage part; the road side drainage part is provided with a guide cavity; and the rain water is drained in time after quickly penetrating through the thinner non-watertight surface layer, thereby ensuring the normal traffic of vehicles and the passerby traffic.

Description

technical field [0001] The invention relates to a drainage system, in particular to a road drainage system. Background technique [0002] In order to facilitate traffic when it rains, the road surface is mostly slightly raised in the middle, and the two sides near the curb are slightly lower than the middle of the road surface. This is to ensure that the driving position in the middle of the road surface is free of water. The drainage of existing ground all is to rely on the sewer outlet that is arranged on the roadside and sewer pipe drainage. Aiming at the above-mentioned technical problems, the Chinese patent literature with the publication number CN101046119A discloses a method for laying a ground or roof rainwater collection system. The waterproof layer has a certain slope or there are several water collecting grooves with a certain slope on it, which can guide rainwater to a designated catchment; lay a permeable surface layer on the waterproof layer; or lay a water-pe...
