Problems solved by technology

For the traffic lanes that account for the vast majority of the municipal road area, they only stay at the drainage pavement stage (only the pavement surface is permeable), and the drainage pavement does not have the "sponge" characteristic, that is, it can only play a drainage role and does not have a temporary water storage function.

Embodiment 1

[0035] Such as figure 1 The shown roadway permeable pavement structure includes a strengthening layer 3, a water sealing layer 4, a base layer 5 and a surface layer 6 arranged on the soil foundation 2;

[0036] The reinforcement layer 3 includes a concrete layer 31 and a first waterproof layer 32 located on the top of the concrete layer 31; the first waterproof layer 32 is formed by curing emulsified asphalt. The thickness of the reinforcing layer 3 is 50 cm; the thickness of the first waterproof layer 32 is 3 mm.

[0037] The water sealing layer 4 includes a porous structure formed by interweaving rock fibers 41 and a second waterproof layer 42 filled in the pores of the porous structure; the thickness of the water sealing layer 4 is 1.5 cm; the porous structure The porosity is 35%. The second waterproof layer 42 is solidified by emulsified asphalt; the rock fibers 41 are basalt fibers.

[0038] The base layer 5 includes a lower base layer 51, a middle base layer 52 and an...

Embodiment 2

[0048] Compared with Embodiment 1, the difference of the roadway permeable pavement structure of this embodiment is: as figure 2 As shown, the drain pipe 11 is provided with a filter device, and the filter device includes a through hole 13 passing through the drain pipe 11 and a filter membrane 12 arranged on the outer surface of the drain pipe 11 .

Embodiment 3

[0050] Compared with Embodiment 1, the difference of the roadway permeable pavement structure of this embodiment is:

[0051] The first waterproof layer 32 is cured from polyurea. The thickness of the reinforcing layer 3 is 60 cm; the thickness of the first waterproof layer 32 is 4 mm.

[0052] The thickness of the water sealing layer 4 is 1 cm; the porosity of the porous structure is 20%. The second waterproof layer 42 is cured from polyurethane.

[0053] The particle size of the first crushed stone is 9.5 mm, the particle size of the second crushed stone 522 is 50 mm; the thickness of the lower base layer 51 and the upper base layer 53 is 10 cm; the thickness of the middle base layer 52 is 25 cm.

[0054] The thickness of the lower layer 61 is 6 cm; the thickness of the upper layer 62 is 6 cm; the maximum nominal particle size of the first gravel 611 is 25 mm; the maximum nominal particle size of the second gravel 621 is 14 mm.

Abstract

The invention discloses a road carriageway porous pavement structure and a pavement method thereof. The structure comprises a water sealing layer arranged on a soil foundation, a base layer and a surface layer; a reinforcing layer is arranged between the water sealing layer and the soil foundation; the water sealing layer comprises a porous structure formed by interweaving and accumulating rock fibers, and second waterproof layers filled in gaps of the porous structure; the base layer comprises a lower base layer, a middle base layer and an upper base layer arranged in sequence from bottom totop; the lower base layer and the upper base layer comprise first rubbles mutually accumulated; the middle base layer comprises an earthwork standard room, and second rubbles filled in gaps of the earthwork standard room; the surface layer comprises a lower surface layer and an upper surface layer arranged in sequence from bottom to top; the lower surface layer comprises first gravels mutually accumulated, and third waterproof layers filled in gaps of the first gravels; the upper surface layer comprises second gravels mutually accumulated, and fourth waterproof layers filled in gaps of the second gravels; and the average particle size of the first gravels is larger than the average particle size of the second gravels.

Description

technical field [0001] The invention relates to the technical field of road pavement structures, in particular to a roadway permeable pavement structure and a laying method thereof. Background technique [0002] With the continuous development of my country's modern industry and the continuous progress of social economy, the pace of urbanization in my country is getting faster and faster, and many towns and villages are gradually incorporated into cities. Judging from the current situation, my country's urbanization construction is still maintaining a rapid construction pace, and the level and quality of urbanization construction have also been improving. my country's urbanization construction, on the one hand, has greatly improved people's living standards and strengthened the national economy; Problems such as heat island effect, noise and light pollution are becoming more and more serious. These problems have greatly affected the quality of life of urban residents, and h...
