Detailed Embodiments
[0022] The present utility model will be further described below in conjunction with embodiments. The description of the following embodiments is only for helping to understand the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
[0023] As an embodiment, as Figures 1 to 6 shown, this PAC drainage asphalt pavement with stainless steel pipe drainage for service area apron includes: a rain grate 1, a road surface, and an anti-odor gate 16. A drainage well is excavated below the road surface.
[0024] Beneath the road surface is a 220-mm-thick concrete base course 9. On the concrete base course 9, an asphalt surface course 8 with a thickness of 60 cm is paved, which is an AC-25 asphalt surface course. A waterproof sealing layer 6 is provided on the asphalt surface course 8, and a 40-mm-thick PAC asphalt surface course 7 is provided on the waterproof sealing layer 6. The PAC asphalt surface course 7 is a PAC-13 drainage asphalt surface course.
[0025] As Figure 1 and Figure 2 shown, stainless steel drainage pipes 2 are obliquely inserted into the concrete base course 9 around the rain grate 1. The top ends of the stainless steel drainage pipes 2 extend to the top surface of the concrete base course 9. Specifically, the top ends of the stainless steel drainage pipes 2 extend to the junction of the concrete base course 9 and the asphalt surface course 8. The bottom ends of the stainless steel drainage pipes 2 penetrate the drainage well wall and extend into the drainage well.
[0026] The bottoms of the stainless steel drainage pipes 2 are wrapped with waterproof geotextiles 10. The waterproof geotextiles 10 extend upward along the bottoms of the stainless steel drainage pipes 2 and extend to form a waterproof isolation zone between the asphalt surface course 8 and the waterproof sealing layer 6.
[0027] A rain grate well seat 4 is installed at the top of the drainage well. The rain grate 1 is installed on the rain grate well seat 4. 3-cm-sized gravel 5 is laid between the asphalt surface course 8 and the rain grate well seat 4. The 3-cm-sized gravel 5 extends to the top ends of the stainless steel drainage pipes 2, specifically extending 100 cm from the outside of the rain grate well seat 4.
[0028] As Figures 2 to 4 shown, a rain inlet cover plate 3 is provided above the rain grate 1. The end of the rain inlet cover plate 3 is connected to the rain grate well seat 4 by high-strength bolts 15. Below the rain inlet cover plate 3, a filter net 11 and a pollution interception groove 12 are sequentially provided. Both ends of the filter net 11 are connected to the rain grate well seat 4 by hooks 14. Filter holes 13 are provided on the sides and bottom of the pollution interception groove 12.
[0029] As Figure 5 and Figure 6As shown in the figure, the odor-proof gate 16 is installed in the sewage well below the rainwater grate 1. The odor-proof gate 16 includes a gate body 17, a movable spring 18 and a movable baffle 19. The movable baffle 19 is arranged at the bottom of the gate body 17. The movable spring 18 is used to control the opening and closing of the movable baffle 19. In the initial state, the movable spring 18 pulls the movable baffle 19 to a state where the bottom of the gate body 17 is closed, preventing the odor from overflowing. When it rains, the movable baffle 19 is pressed down by the gravity, and the automatic opening can be realized.
