[0002] In civil engineering, roads, as an essential structure, are of great significance. The road setting must ensure the rapid drainage of seepage water, so that the accumulated water on the road surface can be effectively drained without pooling, and it can meet the requirements of vehicle passage. Considering that the road is the "face" of the project, its aesthetics are also getting more and more attention. Most of the roads used in engineering are asphalt roads, which are convenient for construction but have insufficient drainage effect, and the maintenance cost is high and time-consuming after being damaged. Moreover, its durability is poor in long-term humid or hot environments, and it lacks overall beauty. Summary of the Invention

The bottom foundation is longitudinally provided with several V-shaped beams and transverse drainage ditches. The bottom foundation is sequentially provided with a gravel layer, an aggregate layer, a fine sand layer, and a brick-paved road surface from bottom to top. A slotted longitudinal drain pipe is arranged on one side of the gravel layer close to the concrete drainage ditch. The slotted longitudinal drain pipe is connected to the transverse drainage ditch, and the transverse drainage ditch is connected to the concrete drainage ditch.

Detailed implementation manners
[0027] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
[0028] As Figure 1-7 shown, a new type of road surface structure includes a bottom foundation 1 and a concrete drainage ditch 2 arranged on one side of the road. The bottom foundation 1 is longitudinally provided with a number of V-shaped beams 3 and transverse drainage ditches 4. The bottom foundation 1 is successively provided with a gravel layer 5, an aggregate layer 6, a fine sand layer 7 and a brick-paved road surface 8 from bottom to top. A slotted longitudinal drain pipe 9 is arranged on one side of the gravel layer 5 close to the concrete drainage ditch 5. The slotted longitudinal drain pipe 9 is connected to the transverse drainage ditch 4, and the transverse drainage ditch 4 is connected to the concrete drainage ditch 2.
[0029] The V-shaped beam 3 is composed of a precast concrete beam 31 and a cast-in-situ concrete beam 32.
[0030] The V-shaped beam 3 is fixed to the bottom foundation 1 through anchor bolts 10.
[0031] The interval between two adjacent V-shaped beams 3 is 30 m.
[0032] The interval between two adjacent transverse drainage ditches 4 is 150 m.
[0033] The gravel layer 5 is 10 cm thick.
[0034] The aggregate layer 6 is 1.5 cm thick and the particle size is 20 cm.
[0035] The fine sand layer 7 is 4 cm thick.
[0036] The bricks of the brick-paved road surface 8 have a thickness of 8 cm.
[0037] Geotextiles are provided on both the gravel layer 5 and the outside of the slotted longitudinal drain pipe 9.
[0038] In this embodiment, taking the road in the tunnel as an example, it includes a bottom foundation 1 and a concrete drainage ditch 2 arranged on one side of the road. A V-shaped beam 3 is arranged every 30 m as the support of the sloping road to prevent sliding. The V-shaped beam 3 is composed of a precast concrete beam 31 and a cast-in-situ concrete beam 32, and there is a concrete joint 33 between them. The beam contains steel bars. The bottom of the precast concrete beam 31 is provided with anchor bolts 10 which are anchored into the bottom foundation 1 (the bottom foundation 1 is not water-permeable); a transverse drainage ditch 4 is arranged every 150 m (that is, a plurality of transverse drainage ditches 4 are arranged side by side). A steel cover plate 14 is installed on the top of the transverse drainage ditch 4. The drainage ditch has a certain slope and communicates with the concrete drainage ditch 2, and can effectively drain the water in the transverse drainage ditch 4 into the concrete drainage ditch 2 and discharge it in time; the road surface is composed of four layers of materials, including a gravel layer 5, an aggregate layer 6, a fine sand layer 7 and a brick-paved road surface 8, as Figure 6As shown, a slotted longitudinal drainage pipe 9 is arranged near the bottom of the concrete drainage ditch 2. The slotted longitudinal drainage pipe 9 is as shown in FIG. Figure 8-9 As shown, the seepage water is collected into the slotted longitudinal drainage pipe 9, and then flows into the transverse drainage ditch 4 through the slotted longitudinal drainage pipe 9 (to discharge the transverse seepage water), and then flows into the concrete drainage ditch 2. A drainage hole 11 is set in the hole and a soft drainage pipe 12 is introduced to introduce the seepage water in the hole into the concrete drainage ditch 2 for timely drainage (to discharge the longitudinal seepage water), and a mortar plugging 13 is set at the connection between the drainage hole 11 and the soft drainage pipe 12.

[0043] S4. A transverse drainage ditch 4 is set every 150m. A steel cover plate 14 is installed on the top of the transverse drainage ditch 4. The transverse drainage ditch 4 is connected to the concrete drainage ditch 2 at a certain slope, so that the water in the transverse drainage ditch 4 can be introduced into the concrete drainage ditch 2 and discharged in time;
[0044] S5, installing a slotted longitudinal drainage pipe 9 at the external footing position near the concrete drainage ditch 2 and wrapping it with geotextile;
[0045] S6. Connect the slotted longitudinal drainage pipe 9 to the bottom of the transverse drainage ditch 4. Set a PVC pipe 15 at the bottom of the transverse drainage ditch 4 with a spacing of 1m to facilitate the smooth entry of seepage water into the transverse drainage ditch 4.

[0047] S8, then laying the aggregate layer 6, the fine sand layer 7 and the brick pavement 8 in sequence;
[0048] S9. For drainage in the hole, drainage holes 11 are set and soft drainage pipes 12 are introduced to guide the seepage water in the hole into the concrete drainage ditch 2 for timely drainage.
