Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0026] Embodiment 1
[0027] Please refer to Figure 1 and Figure 2 , the embodiment provides an asphalt concrete pavement drainage structure, which comprises a road groove 1 opened on an asphalt concrete pavement 5 and a drainage main body 2 arranged in the road groove 1. The road groove 1 spans an overtaking lane, a main lane and a shoulder of the asphalt concrete pavement. The top of the drainage main body 2 is 1-3 mm lower than the asphalt concrete pavement. The bottom of the road groove 1 is provided with a positioning pad 4. The bottom of the drainage main body 2 is provided with a positioning groove 23 matched with the positioning pad 4. The bottom of the drainage main body 2 and the two sides of the drainage main body 2 are provided with an adhesive 3 for connecting the drainage main body 2 and the road groove 1. The drainage main body 2 is provided with a drainage channel 21 and a plurality of drainage holes 22. The drainage channel 21 penetrates through both ends of the drainage main body 2 along the length direction of the drainage main body 2. The drainage holes 22 are arranged at the top of the drainage main body 2 and communicate with the drainage channel 21. In the embodiment, the road groove 1 of the asphalt concrete pavement is provided with the drainage main body 2. The drainage main body 2 is positioned and installed in the road groove 1 by matching the positioning groove 23 with the positioning pad 4. The drainage main body 2 and the road groove 1 are fixedly connected through the adhesive 3. The accumulated water on the road can enter the drainage channel 21 through the drainage holes 22 and be drained from both ends of the drainage main body 2. Since the top of the drainage main body 2 is 1-3 mm lower than the asphalt concrete pavement, that is, the height difference between the drainage main body 2 and the asphalt concrete pavement is small, the vehicle can pass through the drainage main body 2 smoothly. Compared with the groove carving drainage method, the asphalt concrete pavement drainage structure in the embodiment has high structural stability and can greatly improve the driving comfort and safety.
[0028] The asphalt concrete pavement drainage structure of the embodiment can be widely arranged on various asphalt concrete pavements, and has the characteristics of wide applicability, convenient construction, simple construction machinery, small damage to the pavement, small tire noise, etc. As an optimization, the top of the drainage main body 2 is 2mm lower than the asphalt concrete pavement, and the driving comfort and safety are higher.

The drainage main body 2 of the embodiment is made of galvanized seamless steel pipe by laser cutting or water cutting, and the adhesive 3 of the embodiment is HM-120 type A structural adhesive for steel of Hummer brand. The structural adhesive for steel has the characteristics of high strength, aging resistance, corrosion resistance, etc. The drainage main body 2 and the road groove 1 are connected by the structural adhesive for steel, and the overall structural stability is high.
[0030] Further, if the drainage hole 22 is too small, the opening construction is difficult, and the accumulated water is difficult to enter the drainage channel 21 through the drainage hole 22 in time when it rains heavily. If the drainage hole 22 is too large, the driving comfort and safety will be reduced. As an optimization, the opening width of the drainage hole 22 is greater than 25% of the width of the drainage main body 2 and less than 50% of the width of the drainage main body 2. The specification of the drainage main body 2 of the embodiment is 80mm in width, 80mm in height, 8mm in thickness, and the length is arranged according to the width of the asphalt concrete pavement. The opening width of the drainage hole 22 on the drainage main body 2 is greater than 20mm and less than 40mm. The opening width of the drainage hole 22 of the embodiment is 30mm. The thickness of the drainage main body 2 of the embodiment is large, and the bending resistance, torsion resistance and impact resistance are strong. The opening width of the drainage hole 22 is moderate, the plugging frequency is small, and only high-pressure water gun is needed for daily maintenance.
[0031] Further, in order to improve the stability of the asphalt concrete pavement drainage structure, the thickness of the adhesive 3 on both sides of the drainage main body 2 is greater than 15% of the width of the drainage main body 2. The width of the drainage main body 2 of the embodiment is 80mm, so the thickness of the adhesive 3 on both sides of the drainage main body 2 is greater than 12mm. As an optimization, the thickness of the adhesive 3 on both sides of the drainage main body 2 of the embodiment is 15mm.
[0032] Further, in order to strengthen the drainage effect of the drainage main body 2, the top of the drainage main body 2 is provided with a water guide slope 24, the water guide slope 24 is arranged on both sides of the drainage hole 22, and the water guide slope 24 gradually inclines downward from both sides of the drainage main body 2 to the drainage hole 22. The accumulated water on the asphalt concrete pavement enters the drainage hole 22 through the water guide slope 24 under the guidance of the water guide slope 24, which can effectively avoid the rainwater from accumulating on the asphalt concrete pavement to form a water film or an accumulated water layer.
[0033] Further, the drainage body 2 is arranged according to the super lane, the main lane and the shoulder of the asphalt concrete pavement 5, and comprises a super lane drainage body 201, a main lane drainage body 202 and a shoulder drainage body 203. The super lane drainage body 201 is arranged in the road groove 1 of the super lane of the asphalt concrete pavement 5, the main lane drainage body 202 is arranged in the road groove 1 of the main lane of the asphalt concrete pavement 5, and the shoulder drainage body 203 is arranged in the road groove 1 of the shoulder of the asphalt concrete pavement 5.

The drainage body 2 formed by welding has good integrity and stable structure.
[0034] Specifically, the drainage hole 22 comprises a super lane first drainage hole 221 and a plurality of super lane second drainage holes 222. The opening length of the super lane first drainage hole 221 is greater than that of the super lane second drainage hole 222. The super lane first drainage hole 221 is arranged at the middle part of the super lane drainage body 201, and the plurality of super lane second drainage holes 222 are uniformly arranged at the two end parts of the super lane drainage body 201. The two end parts of the super lane are more in contact with the wheels of the driving vehicle, and the plurality of super lane second drainage holes 222 arranged at intervals are arranged correspondingly, which is beneficial to guarantee the stability of the asphalt concrete pavement drainage structure. The middle part of the super lane is less in contact with the wheels of the driving vehicle, and the super lane first drainage hole 221 with a greater opening length is arranged correspondingly, which is beneficial to timely drainage.
[0035] Specifically, the drainage hole 22 further comprises a main lane first drainage hole 223 and a plurality of main lane second drainage holes 224. The opening length of the main lane first drainage hole 223 is greater than that of the main lane second drainage hole 224. The main lane first drainage hole 223 is arranged at the middle part of the main lane drainage body 202, and the plurality of main lane second drainage holes 224 are uniformly arranged at the two end parts of the main lane drainage body 202. The two end parts of the main lane are more in contact with the wheels of the driving vehicle, and the plurality of main lane second drainage holes 224 arranged at intervals are arranged correspondingly, which is beneficial to guarantee the stability of the asphalt concrete pavement drainage structure. The middle part of the main lane is less in contact with the wheels of the driving vehicle, and the main lane first drainage hole 223 with a greater opening length is arranged correspondingly, which is beneficial to timely drainage.
[0036] Specifically, the drainage hole 22 also includes a shoulder drainage hole 225, which is arranged on the shoulder drainage body 203 and penetrates both ends of the shoulder drainage body 203 along the length direction of the shoulder drainage body 203. The shoulder is rarely in contact with the wheels of the vehicle, and the shoulder drainage hole 225 penetrating both ends of the shoulder drainage body 203 is arranged correspondingly, which is beneficial to timely drainage.
