Embodiment 1

[0028] figure 1 The invention discloses a road drainage and water filtration structure, which includes a road surface drainage part and a roadside drainage part.

[0029] Described pavement drainage part is successively from bottom to top: base layer 3, waterproof layer 2, permeable layer 1;

[0030] Wherein, the permeable layer 1 includes, from bottom to top, a coarse sand cushion layer 15 , a gravel layer 14 , a concrete cushion layer 13 , a cement mortar layer 12 and a permeable brick layer 11 . The thickness ratio between the above layers is set according to the existing road paving standards.

[0031] The permeable brick layer 11 is paved with permeable bricks, and the permeable bricks contain aggregate particles and a hydrophilic binder covering the aggregate particles; the particle size of the aggregate particles is 0.045-0.2mm, The above-mentioned aggregate particles are a mixture of slag and glass microspheres in a weight ratio of 3:1. The hydrophilic adhesive is a...

Abstract

The invention discloses a road drainage and filtration structure, which comprises a road surface drainage part and a roadside drainage part; the road surface drainage part is as follows from bottom to top: a base layer (3), a waterproof layer (2), and a water permeable layer (1) ; The roadside drainage part is placed on the outside of the road adjacent to the road surface drainage part, and the roadside drainage part includes a filter water drainage tank (5) located in the lower layer and a seal for closing the filter water drainage tank (5) A water filter cover (4), the upper surface of the side adjacent to the water permeable layer (1) of the water filter cover (4) is flush with the upper surface of the water permeable layer (1), and the water filter cover A water filter drain (41) is formed on the plate (4). The road drainage and filtration structure solves the problems of poor drainage performance, easy drainage blockage, and frequent maintenance and cleaning of the existing road drainage system when there is heavy rainfall; Trouble with traditional rainwater follow-up treatment.

Description

technical field [0001] The invention relates to the technical field of road paving, in particular to a road drainage and filtering structure. Background technique [0002] In order to facilitate traffic when it rains, most of the existing roads in the city are slightly raised in the middle, and the two sides near the curb are slightly lower than the middle of the road. This is to ensure that the driving position in the middle of the road is free of water. Existing ground drainage all is to rely on the sewer that is arranged on the roadside and sewer pipe drainage. When the amount of rainwater is large, ponding will form at the drain. [0003] In view of the above technical problems, Chinese patent document CN101649592B discloses a road drainage system, comprising a road drainage part and a roadside drainage part, and the road drainage part is sequentially from bottom to top: a base layer, a waterproof layer, and a water-permeable layer, and the waterproof layer There is a ...
