In addition, the rainwater collides with the first and second convex portions 11 and 12, so that the rainwater flow can be weakened and can easily flow into the water outlet 10.

  As shown in FIG. 2, a through hole 14 for allowing rainwater to flow is formed in the side plate portion 2 b. This through-hole 14 is for taking in the rainwater which permeate | transmitted when the surrounding pavement which installed the cover apparatus 1 is water-permeable.

  As shown in FIG. 3, the reinforcing ribs 13 are provided along the first and second hook-like parts 3 and 4 on the back side of the first and second hook-like parts 3 and 4 with respect to the top plate part 2a. Is provided. For this reason, the position of the 1st and 2nd bowl-shaped parts 3 and 4 and the reinforcement rib 13 corresponds in the front and back of the top-plate part 2a. Therefore, it is possible to ensure a large area for drilling the flowing water port 10 for the top plate portion 2a.

  In addition, since the 1st and 2nd bowl-shaped parts 3 and 4 and the inner surface 8 are in a position higher than the top-plate part 2a, the height of the 1st convex part 11 is higher than the height of the 2nd convex part 12. Is also expensive. Specifically, the first convex portion 11 has a two-stage shape in which a columnar base portion and a columnar tip portion having a diameter smaller than that of the base portion are overlapped. The uppermost surfaces of the first convex portion 11 and the second convex portion 12 are, for example, 5 mm in diameter, and the distance between the centers of the adjacent first and second convex portions 11, 12 is, for example, 25 mm. Depending on the arrangement of the flowing water port 10, there is also a portion formed in a range of, for example, 13.63 mm to 33.87 mm. The short width of the water flow port 10 is the largest at the outer edge frame 2d side, for example, 13 mm. Others are, for example, 10 mm. Thereby, the rainwater which flows in from the outer edge frame 2d side can flow into the water flow port 10 efficiently.

  Further, the width of the first hook-shaped portion 3 increases from the outer end portion 3a toward the inner end portion 3b. Thereby, rainwater can be guided efficiently and led to the water collection area 9. Further, the side plate portion 2b is provided with a step portion 15 as a mark when excavating and refilling the pavement. A line may be drawn instead of the step portion 15.

  When the lid device 1 as described above is used for the side groove, the top surface of the top plate portion 2a is exposed to the road surface as shown in FIG.

Accordingly, the anchor bolts 16 are erected so as to extend upward from the upper end surface of the side wall 18a. Next, the height adjusting member 7 is screwed into each of the anchor bolts 16. The height adjusting member 7 can move up and down while being screwed along the anchor bolt 16. Then, the anchor bolts 16 are inserted into the four outer insertion holes 22 (see FIG. 1) using the marks 26 (see FIG. 1) provided on the flange portion 2c as marks, and fixed with the nuts 21. At this time, the height of the flange portion 2 c can be adjusted by the height adjusting member 7. Therefore, since the lid member 2 can be tilted, when the channel is inclined differently from the road, the slope construction for tilting the top plate portion 2a according to the road can be easily performed. And the mortar 6 is filled between the flange part 2c and the upper end surface of the side wall 18a. At the time of filling, the inner side of the side wall 18a is pressed by the inner plate 17 and the outer side is pressed by the outer plate (not shown) so that the mortar does not leak.

  After solidifying the mortar, the earth and sand 19 are backfilled, and the upper side thereof is paved with a paving material 20 such as asphalt. In the side groove 5 having such a lid device 1, the side groove main body 18 is embedded in the ground, and what is exposed on the road surface is the top plate portion 2 a of the lid member 2 that is integrally fixed to the side groove main body 18. Therefore, it is possible to suppress the occurrence of rattling due to the passage of the vehicle.

The first hook-shaped portion 3 extends radially from the second hook-shaped portion 4 toward the outer edge portion of the top plate portion 2a. Specifically, the first hook-shaped portion 3 has its inner end 3b in contact with the second hook-shaped portion 4 and extends radially toward the outer edge frame 2d. The outer end 3a extends to the vicinity of the outer edge frame 2d. The top plate portion 2 a can be separated into a lid body 23 and a substrate portion 24. A circle 25 is formed on the top plate portion 2a so as to be concentric with the second shore portion 4 and located outside the outer end portion 3a of the first shore portion 3, and the lid body 23 is formed from the circle 25. Is also the inner part. The substrate part 24 is an outer part of the circle 25. By providing the separable lid body 23 in this way, it becomes easy to remove the lid body 23 and perform maintenance of the side groove embedded in the ground.

  The water flow port 10 and the first convex portion 11 provided on the lid body 23 (between the first hook-shaped portions 3) are intermittently disposed along a concentric circle with the second hook-shaped portion. . And the 1st convex part 11 between the concentric circles adjacent to radial direction is arrange | positioned in the radial direction from the center of the top-plate part 2a. For this reason, even if rainwater exceeds the front water outlet 10, it can collide with the first convex portion 11 and flow into the next water outlet 10. Moreover, since the 1st convex part 11 is arrange | positioned along the water outlet 10 along a concentric circle, it can act as a guide for making rainwater flow in into the water outlet 10. Such a lid | cover apparatus 1 can be utilized as a lid | cover of a water collecting tank located in the branch point of the side groove 5 mentioned above. The distance between the centers of the adjacent first and second convex portions 11 and 12 is, for example, 25 mm.
