Abstract
Description
Technical Field
[0001] The present application relates to the technical field of road engineering, and in particular to a pavement structure provided with a drainage layer. Background Art
[0002] With the acceleration of urbanization, road drainage problems are becoming increasingly prominent, especially during the rainy season. Waterlogging on roads not only affects traffic but can also damage road structures and even cause safety accidents.
[0003] Regarding the above-mentioned related technologies, the inventors believe that most traditional pavement structures use simple permeable asphalt pavements with a small amount of water absorption. This type of pavement can speed up the drainage of water from the road surface, but most ordinary road base structures are not equipped with a road surface water drainage structure. When encountering heavy rainfall, road surface water is often accumulated due to poor drainage, which not only affects driving safety, but also easily causes damage to the road surface and shortens its service life. Therefore, a pavement structure with a drainage layer is proposed to solve the above problems. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The present application embodiment discloses a pavement structure with a drainage layer. Figure 1-3 A pavement structure provided with a drainage layer includes a pavement layer mechanism 1 and a drainage layer mechanism 2. The drainage layer mechanism 2 is provided on the bottom outer wall of the pavement layer mechanism 1, and a road cushion mechanism 3 is provided at the bottom of the drainage layer mechanism 2. The road cushion mechanism 3 includes a waterproof earthwork cloth 301 and a base soil layer 302. The waterproof earthwork cloth 301 is laid on the surface of the base soil layer 302 to prevent soil particles from entering the drainage layer mechanism 2 and to prevent moisture from penetrating the base soil layer 302.
[0021] The drainage layer structure 2 includes a base layer 201, which provides stable support for the pavement structure. The top outer wall of the base layer 201 is provided with a plurality of drainage grooves 202, which are evenly distributed on the surface of the base layer 201 in an equidistant linear array. The inner wall of the drainage groove 202 is provided with a drainage pipe 203, and the outer wall of the drainage pipe 203 is provided with a plurality of water permeable holes 204. Water that permeates downward through the pavement layer structure 1 will flow into the drainage pipe 203 through the water permeable holes 204.
[0022] The pavement layer structure 1 includes an upper layer 101, a sandless concrete layer 102 and a stone chip layer 103. The stone chip layer 103 is laid on the top of the base layer 201, the sandless concrete layer 102 is laid on the top outer wall of the stone chip layer 103, and the upper layer 101 is arranged on the top outer wall of the sandless concrete layer 102. The sandless concrete layer 102 and the stone chip layer 103 together form a good infiltration system for accelerating the infiltration of rainwater.
[0023] The upper layer 101 is made of highly wear-resistant and anti-slip materials, which can ensure driving safety. It is the surface layer of the road that is in direct contact with the atmosphere.
[0024] Drainage ditches 4 are installed on the outer walls of both sides of the pavement layer mechanism 1, the drainage layer mechanism 2 and the road cushion layer mechanism 3. The top outer wall of the drainage ditch 4 is provided with an interception net 5. Both ends of multiple drainage pipes 203 pass through and extend to the inner cavity of the two drainage ditches 4. The drainage ditches 4 are used to limit the structures on both sides of the pavement layer mechanism 1, the drainage layer mechanism 2 and the road cushion layer mechanism 3 to increase the overall structural stability, and the water in the multiple drainage pipes 203 will be discharged into the drainage ditches 4 on both sides through their two ends.
[0025] The pavement structure provided with a drainage layer in the embodiment of the present application is implemented as follows: debris on the original pavement is cleaned to ensure that the base soil layer 302 is flat, and a waterproof earthwork cloth 301 is laid on the base soil layer 302 to ensure that it is flat and wrinkle-free; then, a base layer 201 is laid on the waterproof earthwork cloth 301 to form a drainage layer; then, a drainage ditch 202 is dug above the base layer 201, and a drainage pipe 203 is installed; a stone chip layer 103 and a sandless concrete layer 102 are laid on the drainage ditch 202 in sequence; finally, an upper layer 101 of a highly wear-resistant and highly anti-skid material is laid on the sandless concrete layer 102, and the entire road construction is completed;
[0026] Drainage ditches 4 are stacked on both sides of the pavement layer mechanism 1, the drainage layer mechanism 2 and the roadbed layer mechanism 3, and the two ends of the drainage pipe 203 inside the drainage groove 202 pass through the two drainage ditches 4. When the road encounters heavy rainfall, most of the rainwater flows toward both sides on the upper layer 101, and the rainwater flows into the drainage ditch 4 through the interception net 5 for discharge, effectively avoiding the formation of water accumulation. Then, part of the rainwater penetrates into the sandless concrete layer 102 and the stone chip layer 103 through the upper layer 101. The sandless concrete layer 102 and the stone chip layer 103 form a good infiltration system, which accelerates the infiltration of rainwater. The rainwater flows into the base layer 201 and is diverted by multiple drainage grooves 202. When the rainwater enters the drainage groove 202, it flows into the multiple drainage pipes 203 through the multiple water-permeable holes 204. The multiple drainage pipes 203 quickly discharge the rainwater into the two drainage ditches 4 for discharge.
[0027] In summary, the pavement structure provided with a drainage layer proposed in the present invention realizes rapid and efficient drainage of rainwater by rationally setting the pavement layer mechanism 1, the drainage layer mechanism 2 and the road cushion layer mechanism 3, while enhancing the stability and durability of the pavement structure.
