Problems solved by technology

[0011]2. The combination between the permeable surface layer and the cushion layer of the pavement is weak, and the brick pavement is easy to "turn bricks"
The current permeable cement concrete pavement, permeable brick + permeable cement concrete cushion permeable pavement, etc., during the excavation of the subgrade, often produces a large amount of concrete waste when the permeable cement concrete surface or cushion is damaged, resulting in material damage. waste
The removal and recycling of these concrete wastes requires a lot of energy

Embodiment 1

[0084] Embodiment 1: (Pavement surface unit direct paving type 1).

[0085] Such as figure 1 A new semi-flexible permeable roadway is shown, which includes a permeable roadbed 100 composed of an original soil layer 101, a gravel cushion 102, and a coarse sand cushion 104, and is paved on the leveled permeable roadbed 100 One layer is a permeable grid cushion layer composed of several permeable grid panels 10 , and a pavement surface course 200 composed of several permeable pavement bricks 20 is laid on the permeable grid panels 10 .

[0086] Such as figure 2 with image 3 As shown, this Example The quadrilateral water-permeable grid plate 10 is integrally injection-molded by thermoplastics, and the lattice sheets 12 in the water-permeable grid plate 10 form water-permeable holes 11 that run through its upper and lower planes. The water-permeable holes 11 in this embodiment are quadrangular prism holes.

[0087] Such as figure 1 ~ image 3 As shown, the ab...

Embodiment 2

[0095] Embodiment two: (walkway surface unit direct pavement type two).

[0096] This embodiment is the same as the embodiment for the direct laying of the surface unit, the difference is that the pavement surface 200 is composed of colored prefabricated permeable asphalt paving blocks, and its surface water permeability coefficient is required to be ≥ 1.1×10 -2 cm, pavement compressive grade Cc35. The paving steps and methods of the roadway:

[0097] ①. Compact the original soil layer 101 with an 8-ton road roller, and the degree of compaction is 90-92%.

[0098] ②. Lay a graded gravel layer 102 with a particle size of 3-5 cm and a thickness of 16-20 cm. Use an 8-ton road roller to compact and rough level the layer, and the compaction degree is 92%.

[0099] ③. Lay a graded coarse sand cushion layer 103 with a particle size of 2 to 4 mm and a thickness of 4 cm. Compact it with an 8-ton road roller and do fine leveling. The compaction degree is 92%.

[0100] ④. Lay modifi...

Embodiment 3

[0102] Embodiment three: (brick body frame limit type).

[0103] This embodiment applies figure 2 Shown permeable grid plate, cooperate to use as described in the present invention Figure 4 grid shown and Figure 4 As shown in the schematic diagram, a kind of permeable pavement is laid; the pavement surface layer is required to have a water permeability coefficient of 200 ≥ 1.0×10 -2 cm, pavement compressive grade Cc35. The paving steps and methods of the roadway:

[0104] ①. Compact the original soil layer 101 with an 8-ton road roller, and the degree of compaction is 90-92%.

[0105] ②. Lay a graded gravel cushion layer 102 with a particle size of 2 to 4 cm and a thickness of 18 cm. Compact it with an 8-ton road roller and perform rough leveling. The compaction degree is 92%.

[0106] ③. Lay a graded coarse sand cushion layer 103 with a particle size of 2-4 mm and a thickness of 4 cm. Compact and level with an 8-ton road roller, with a compaction degree of 92%...

Abstract

The invention relates to a semi-flexible structure permeable street and a pavement method thereof. The structure of the street comprises a fully-permeable multilayer pavement structure roadbed or a drainage multilayer pavement structure roadbed, a permeable grid plate cushion paved on the roadbed, and a street surface layer paved on the permeable grid plate cushion. By paving the permeable cushion formed by the linked pavement of permeable grid plates on the fully-permeable multilayer pavement structure roadbed or the drainage multilayer pavement structure roadbed, the semi-flexible structure permeable street which is constructed on condition that the permeable grid plate structure is reasonably designed, the manufacturing material of the permeable grid plate cushion is reasonably selected and the unit structure of the street surface layer is reasonably designed has the advantages of good permeability and strong water storage capability, and the surface layer and the permeable grid plate cushion of the street have a good combination degree and are easy to disassemble, replace and maintain.

Description

technical field [0001] The invention relates to a system design and pavement method of a semi-flexible structure permeable walkway, in particular to a semi-flexible structure permeable structure with good water permeability and drainage, strong water storage capacity, and easy disassembly, replacement and maintenance of the walkway surface A sidewalk and a laying method thereof belong to the application field of ecological environmental protection technology. Background technique [0002] Traditional permeable pavement materials are composed of various permeable pavement bricks (hereinafter referred to as permeable bricks), permeable cement concrete pavement and permeable asphalt pavement. What is more important for the construction of urban ecological permeable roadways is whether the subgrade cushion laid under the permeable surface material of the roadway has good water permeability, drainage and water storage functions, and whether the base layer can have a good relation...
