Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

As shown in fig. 1 to 4, the utility model provides a road drainage structure, which comprises a road base layer 1, a waterproof layer 2, a permeable layer 3, a road surface layer 4, a seepage drainage pipe 5, an inner filter screen 6, an edge drainage groove 7, a top cover plate 8, an emergency drainage mechanism 9, an emergency drainage interlayer 901, an inner drainage groove 902, a top transfer pipe 10 and a bottom drainage pipe 11, wherein the waterproof layer 2 is arranged at the top of the road base layer 1, the top of the waterproof layer 2 is connected with the bottom of the permeable layer 3, the road surface layer 4 is paved at the top of the permeable layer 3, the edge of the top surface of the waterproof layer 2 is fixedly connected with one end of the top of the seepage drainage pipe 5, the seepage drainage pipe 5 is fixedly arranged on the road base layer 1 at the side of the waterproof layer 2, the emergency drainage mechanism 9 is arranged outside the road base layer 1, the side of the bottom of the road surface layer 4 is connected with the top end of the inner filter screen 6, the bottom of the inner filter screen 6 is connected with one side of the emergency drainage mechanism 9, the edge of the top surface layer 4 is provided with the edge drainage groove 7, the edge drainage groove 7 is connected with the top cover plate 8, and the other end of the top cover plate 8 is connected with the top of the emergency drainage mechanism 9.

The emergent drainage mechanism 9 of this example includes emergent drainage interlayer 901 and interior drainage tank 902, and interior drainage tank 902 has been seted up to emergent drainage interlayer 901 inboard, and emergent drainage interlayer 901 outer wall one side is connected fixedly with interior filter screen 6 bottom, runs through on the emergent drainage interlayer 901 lateral wall of interior filter screen 6 top and is fixed with a top transfer pipe 10, and interior drainage tank 902 opposite side bottom runs through and is fixed with end drain pipe 11, and foretell structural design can be when the surface runoff is great, carries out quick discharge to rivers, avoids the rainwater to gather at the earth's surface.

The top surface of the emergency drainage interlayer 901 is provided with an inclined surface, the emergency drainage interlayer 901 is symmetrically distributed about the pavement layer 4, and the surface runoff can be rapidly discharged from the pavement layer 4 when the rainwater amount is large due to the structural design.

The diameter of the seepage drain pipe 5 is larger than the width of the inner drain groove 902, the bottom end height of the inner drain groove 902 is lower than the bottom end height of the seepage drain pipe 5, the seepage drain pipe 5 can quickly drain rainwater through the above structural design, and when the rainwater amount is large, the inner drain groove 902 can quickly drain overflowed rainwater, so that the drainage effect is guaranteed.

The interior filter screen 6 is the slope setting, and interior filter screen 6 top is higher than permeable layer 3 top, and permeable layer 3 top surface center highly is higher than permeable layer 3 top surface edge's height, and foretell structural design can effectively hold back fallen leaf branch to when filter screen 6 appears blocking or rivers are unsmooth, derive fast the rainwater and shift, avoid the rainwater to accumulate.
