Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses waterproof roadbed. Referring to fig. 1, the waterproof roadbed comprises a bottom layer 1, wherein a first impermeable layer 2, a cushion layer 3, a base layer 4 and a surface layer 5 are sequentially arranged on the bottom layer 1, a diversion structure for guiding accumulated water on the road surface to two sides of the roadbed is arranged on one side, far away from the bottom layer 1, of the surface layer 5, the diversion structure is a diversion trench 6 arranged on the surface, far away from the bottom layer 1, of the surface layer 5, and the diversion trench 6 is obliquely and downwardly extended from the middle of the surface layer 5 to two sides and is arranged at intervals along the extending direction of the roadbed. And both sides of the surface layer 5 are provided with a water dripping line 7 arranged along the extension direction of the roadbed and a water drainage groove 8 positioned below the water dripping line 7, and the water dripping line 7 is positioned below the water outlet end of the diversion trench 6.

When raining, surface gathered water flows to the both sides of the roadbed along the diversion trench 6, flows out from the diversion trench 6, and water falls on the water dripping line 7, then falls into the water drainage tank 8 under the guide of the water dripping line 7, so reducible surface gathered water directly erodes the roadbed side when flowing down along the both sides of the roadbed, and the problem that the roadbed side structure is damaged easily because of the road surface water flowing down along the both sides of the roadbed in the correlation technique is improved.

In this embodiment, the first impermeable layer 2 is a geomembrane layer, the cushion layer 3 is a sandstone layer, the base layer 4 is a concrete layer, and the surface layer 5 is an asphalt layer.

In order to discharge water in the drainage channels 8, referring to fig. 1, drainage ditches 9 extending along the roadbed are arranged on both sides of the bottom layer 1, and a first drainage pipe 10 extending to the drainage ditches 9 is communicated with the bottom of the drainage channels 8.

Water in the water drainage tank 8 can get into the escape canal 9 through first drain pipe 10, in time drains away by escape canal 9 again, has reduced the ponding in the water drainage tank 8 to help avoiding the condition of a large amount of ponding in road surface.

In order to reduce the influence of water accumulated in the roadbed on the roadbed, referring to fig. 1, a drainage mechanism for draining the water accumulated in the base course 4 is arranged between the base course 4 and the cushion 3. Drainage mechanism is including installing in the second drain pipe 11 of basic unit 4 with 3 juncture in bed course, and second drain pipe 11 arranges along the road bed extending direction interval, and a plurality of inlet openings 12 have been seted up to one side that second drain pipe 11 is close to basic unit 4, and the both ends of second drain pipe 11 communicate with the first drain pipe 10 that is located the road bed both sides respectively. To reduce the corrosion of the first and second drain pipes 10 and 11 by rainwater, the first and second drain pipes 10 and 11 may be high-strength hard plastic pipes.

When the rainwater penetrated into basic unit 4 by surface course 5, the rainwater passed through inlet opening 12 and got into in the second drain pipe 11, then flowed into escape canal 9 through first drain pipe 10, so the inside ponding of reducible road bed is favorable to prolonging the life of road bed.

Further, referring to fig. 1, a filter layer 13 is disposed between the second drain pipe 11 and the base layer 4. In this embodiment, the filter layer 13 is a sponge layer. The reducible silt of filter layer 13 passes through inlet opening 12 circumstances that gets into second drain pipe 11, is favorable to avoiding second drain pipe 11 to be blockked up by silt, guarantees that the drainage normally goes on.

In order to enhance the waterproof performance and strength of the side of the roadbed, referring to fig. 1, second impermeable layers 14 are arranged on both sides of the roadbed, and a reinforcing layer 15 is arranged on the second impermeable layers 14. In this embodiment, the second impermeable layer 14 is a geomembrane layer, and the reinforcing layer 15 is a reinforced concrete layer.

The second impermeable layer 14 can enhance the waterproof capability of the side of the roadbed, and reduce the condition that rainwater penetrates into the inner part of the roadbed from the side of the roadbed. The reinforcing layer 15 can increase the strength of the side face of the roadbed, and is beneficial to prolonging the service life of the roadbed.

The implementation principle of a waterproof road bed of the embodiment of the application is as follows: when raining, the accumulated water on the road surface flows to the two sides of the roadbed along the guide grooves 6, and after flowing out of the guide grooves 6, the water falls on the water dripping lines 7, then falls into the water drainage grooves 8 under the guide of the water dripping lines 7, and then enters the water drainage ditches 9 through the first water drainage pipes 10, so that the direct scouring of the side surface of the roadbed when the accumulated water on the road surface flows down along the two sides of the roadbed can be reduced, and the problem that the side surface structure of the roadbed is easily damaged when the water on the road surface flows down along the two sides of the roadbed in the related technology is solved; when the rainwater entered basic unit 4 by 5 infiltration of surface course, got into in the second drain pipe 11 through inlet opening 12, then flowed into escape canal 9 through first drain pipe 10, so reducible inside ponding of road bed is favorable to prolonging the life of road bed.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
