DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] like Figure 1-Figure 4 As shown, a road surface rapid drainage structure includes a road surface groove 1 and a channel steel 2 fixed in the road surface groove 1, wherein the channel steel 2 is located in an asphalt layer 4 of the road surface and is perpendicular to the length direction of the road surface, one end of the channel steel 2 extends into a road surface drainage facility 5, and a side wall of the channel steel 2 is provided with a channel steel groove 201 on one side close to the inner wall of the road surface groove 1, and the channel steel groove 201 is perpendicular to the length direction of the channel steel 2.

[0028] Through the above technical solution, when there is water accumulation on the road surface, the water on the road surface flows into the existing road surface drainage facilities 5 through the channel steel 2, and the water can be quickly drained through the channel steel 2 to avoid water accumulation on the road surface. At the same time, the channel steel 2 is placed in the road surface groove 1, and the road surface around the road surface groove 1 is protected by the channel steel 2 from being crushed when vehicles pass by. At the same time, the channel steel groove 201 is set on the side wall of the channel steel 2 to increase the friction between the channel steel 2 and the surrounding materials to avoid displacement during long-term use.

[0029] Furthermore, the plurality of pavement grooves 1 are evenly arranged along the length direction of the pavement, the pavement grooves 1 are horizontally arranged or inclined along the pavement drainage facilities 5 , and the top surface of the channel steel 2 is flush with the top surface of the pavement grooves 1 .

[0030] Through the above technical solution, multiple road grooves 1 and channel steels 2 are arranged along the length direction of the road surface according to the water accumulation situation to improve the drainage capacity, and the road grooves 1 and channel steels 2 are arranged obliquely on the flat road surface to improve the drainage capacity. The top of the channel steel 2 is flush with the top of the road groove 1, which is convenient for vehicles to pass and avoids excessive squeezing of the channel steel 2.

[0031] Furthermore, a first waterproof adhesive layer 101 is provided at the bottom of the pavement groove 1 , a rubber gasket 102 is provided on the first waterproof adhesive layer 101 , a second waterproof adhesive layer 103 is provided on the rubber gasket 102 , and the channel steel 2 is located above the second waterproof adhesive layer 103 .

[0032] Through the above technical solution, a road groove 1 is carved on the road surface by a groove carving machine, and the depth of the road groove 1 shall not exceed the depth of the road waterproof layer, so that the channel steel 2 is in the asphalt layer 4; then, a first waterproof bonding layer 101 is set while the road groove 1 is kept dry in the groove, and then a layer of rubber gasket 102 is placed, and then a layer of high-viscosity second waterproof bonding layer 103 is set on the rubber gasket 102; at the same time, a third waterproof bonding layer 104 is set on the inner wall. Then the channel steel 2 is placed, and finally the asphalt sealant 105 is filled in the side wall pores, and the channel steel groove 201 is filled with the asphalt sealant 105, so that the channel steel 2 can be fixed in the road groove 1. The multi-layer waterproof bonding layer can effectively prevent water from entering the roadbed and avoid damaging the roadbed strength, and can also play the role of bonding materials; at the same time, the rubber cushion layer can disperse the force to avoid damage to the road surface when the vehicle presses on the channel steel 2 when the bottom is uneven.

[0033] Furthermore, a blowing device 3 is provided in the channel steel 2 , and the blowing device 3 is located at a side of the channel steel 2 away from the road drainage facility 5 . The blowing device 3 includes an air cylinder 301 , a piston rod 302 , an air outlet 304 and an air inlet pipe 305 .

[0034] According to the above technical solution, when the first spring 308 is in the initial state, the piston rod 302 is lifted up by the elastic force of the first spring 308, the pressure plate 303 extends out of the channel steel 2, and there is gas in the air cylinder 301. When the vehicle passes the pressure plate 303, the wheel presses the pressure plate 303, so that the piston rod 302 compresses the first spring 308, and at the same time, the gas in the air cylinder 301 pushes open the first check valve 306, specifically, the air pushes open the push plate of the first check valve 306 and compresses the spring in the first check valve 306, forming a gas outlet flow channel. The compressed air in the air cylinder 301 flows out from the first check valve 306, and the compressed air flowing out of the air outlet 304 is used to purge the debris in the channel steel 2. At this time, since the second check valve 307 in the air inlet pipe 305 is opposite to the direction of the first check valve 306, when the piston rod 302 compresses the air cylinder 301 to discharge the air, the air cannot pass through the second check valve 307.

[0035] When the vehicle passes by, the pressure plate 303 is reset under the action of the first spring 308, and the first check valve 306 is also reset under the action of the spring, so that the air outside the air outlet 304 cannot enter the air cylinder 301 from the air outlet 304. At this time, the negative pressure in the air cylinder 301 drives the second check valve 307 to open, sucking in the external air to complete the inflation of the air cylinder 301. By setting the air inlet pipe 305, the air inlet pipe 305 and the second check valve 307 are higher than the bottom of the channel steel 2, so as to prevent the accumulated water from entering the air cylinder 301 through the air inlet pipe 305.

[0036] Therefore, the purging device 3 can be used to continuously purge the debris in the channel steel 2 during the driving process of the vehicle, so as to prevent the debris from affecting the drainage effect.

[0037] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
