To lay the impermeable layer 3, the first reference Kakarigokata portion 7a ₁ provided on the lower edge of the cut slope portion 7a of one side above A ₁ underdrain body 1 facing the pavement surface 4 side A water-impermeable layer 3 on the upper surface, a water-impermeable sheet 13 on the upper surface of the water-impermeable layer 3, and a water-permeable layer 4A on the upper surface of the sheet 13, respectively. When laying a roadbed material such as sand, gravel, crushed stone, or the like on the lower surface of the water-impermeable layer 3, this is useful for setting the thickness of the laid material.

The road pavement surface 4 having water permeability is prepared by kneading an aggregate 10 such as natural stone, crushed stone, steel furnace residue, minerals, sand, etc. having a desired particle size with a binder made of cement or a synthetic resin adhesive for a desired time. The road pavement surface 4 is paved with the water-permeable road pavement material which connects the aggregates 10 with each other and forms a continuous gap in the thickness direction between the aggregates 10.

Then, the O-ring 14 and the concave portion 15 are
It is not always necessary to provide the culvert main body 1 by providing a fitting means composed of a convex portion and a concave portion, so that the culvert main body 1 may be connected to achieve watertightness.

One embodiment of the present invention has the above configuration.
The point that the culvert body 1 is laid along the curb block 6 at the boundary between the road and the pavement 5 is the same as the conventional construction method. However, in this embodiment, in FIG. 2 provided above one side of the culvert main body 1, the water-impermeable sheet laid along the gradient θ of the road pavement surface 4 with respect to the four water collecting window holes 8A. Face one end of 13. At this time, the laying impermeable layer 3, first Kakarigokata portion provided on the lower edge of the cut slope portion 7a which is provided on one side above A ₁ underdrain body 1 facing the pavement surface 4 side 7a ₁
The laying thickness of the water-impermeable layer 3 is set on the upper surface of the water-impermeable layer 3 on the upper surface thereof, and the water-impermeable sheet 13 is placed on the upper surface of the water-impermeable layer 3 along the road surface gradient θ toward the water collecting window hole 8A. laying to Te ensuring the laying gradient theta _3. Then, an aggregate 10 such as natural stone, crushed stone, residue such as steel, minerals, sand, etc., having a desired particle size is kneaded with a binder made of cement or a synthetic resin agent for a desired time on the upper surface through the water-impermeable sheet 13. Thus, the road pavement surface 4 is laid while adjusting the laying thickness so that the permeable layer 4A having a continuous gap in the thickness direction between the aggregates 10 substantially matches the top surface 1a of the culvert main body 1.
At this time, since the mesh-like filter member 9 is stretched in the four water collecting window holes 8A with a synthetic resin or a metal wire, when the road pavement surface 4 is paved, the filter member 9 forms the permeable layer 4A. Aggregate 10 is prevented from entering the culvert main body 1 from the water collecting window hole 8A.

The rain, water, and the like, which have fallen on the road, partially penetrate into the permeable layer 4A having water permeability, and the impermeable layer 3 such as asphalt or concrete laid below the permeable layer 4A. becomes running water W ₁ along the laying gradient theta ₃ of water impermeable sheet 13 laid on the upper surface of the impermeable layer 3,
It flows toward the culvert main body 1 in the permeable layer 4A having continuous voids. The rain that falls on the road, in addition to a portion of the water flows along the surface of the permeable layer 4A as a road pavement surface 4 toward the top surface 1a of the culvert body 1 as flowing water W ₂ to the gradient of the road surface θ of the road .

Among them, the flowing water W flowing toward the culvert main body 1 along the laying gradient θ ₃ of the sheet 13 in the permeable layer 4A.
₁ is a plurality of appropriately provided above one side of the culvert main body 1, that is, one side above the culvert main body 1 facing the edge 4a of the permeable road pavement surface 4, and in FIG. The water is collected by flowing into the culvert main body 1, and flows from the upstream side to the downstream side through the water flow hole 2 in the longitudinal direction X inside the culvert main body 1.

[0023] In this case, four catchment window opening 8A is widens as the opening of the outer surface is narrow toward the back as shown in FIGS. 1 and 5, moreover since it is formed on a descending slope, running water W ₁ Is a water flow hole 2 without stopping from the water collection window hole 8A.
Runs down inside. Also, on the left and right sides of the water collection window 8A,
As shown in FIG. 2 and FIG. 4, the cross section at the end edge of the culvert main body 1 and at a substantially intermediate point of the water collecting window hole 8A has a mountain height and a continuous mountain shape having a slope θ ₂ which falls toward the water collecting window hole 8A. Since the water guiding slopes 12a and 12b are formed,
Flowing water flowing in the water-permeable layer 4A along the impermeable sheet 13 W ₁ are chevron water guide slope portion 12a which cross section is formed towards the bowler and without catchment window opening 8A, edge slope of 12b theta ₂ Is collected in the water collection window 8A from the left and right,
It is efficiently introduced into the culvert main body 1 from the water collecting window 8A.
In addition, a mesh-shaped filter member 9 is stretched in the water collecting window hole 8A, so that sand,
Dust is prevented from flowing along with running water W ₁ in the water collecting window hole 8A is only running water W ₁ flows into culvert body 1 from the water collecting window opening 8A.

A part of the rain falling on the road pavement surface 4 and the snow which does not penetrate into the permeable layer 4A out of the snow becomes the running water W ₂ along the gradient θ on the surface of the road pavement surface 4A. It flows toward the top surface 1a. As shown in FIGS. 3 and 4, four water collecting window holes 8B are formed above the other side of the culvert main body 1 facing the curb block 6 of the pavement 5 through a cut-off slope 7b having a tapered cross section. Culvert block 1

It flows down to the setting side of the curb block 6. Then this running water W ₂
The culvert extends from the water collecting window hole 8B on the side opposite to the water collecting window hole 8A provided on the road pavement surface 4 through the cutting slope 7b of the constriction formed with a gap K from the curb block 6. by flowing into the main body 1, and joins the water flow W ₁ that flows from the aquifer 4A, it flows to the downstream side of the running water hole 2 from the upstream side. At this time, the water collecting window hole 8B has a narrow opening on the outer surface and becomes wider as it goes deeper, and is formed with a downward slope, so that dirt and debris present on the upper surface of the road pavement surface 4 can be collected in the water collecting window hole 8B. Is prevented from flowing into the culvert main body 1 through the water collecting window hole 8B without interruption.

[0025] When laying the underdrain block 6, readily curb the second reference Kakarigokata portion 7b ₁ provided on the lower edge of the cut slope portion 7b provided on the other side above A ₂ of underdrain blocks 1 The pavement 5 can be adjusted by adjusting the laying height of the block 6.
And the gap K between the curb block 6 and the top surface 1a of the culvert block 1 with respect to the water collecting window hole 8B is sufficiently ensured.

The upper part of the culvert main body 1 is covered with a top surface 1a, and the top surface 1a is not provided with a water collecting hole having a large opening unlike the conventional case. It can sufficiently withstand the weight of the vehicle, and has high strength against external forces such as earthquakes, and the structure becomes robust.

[0027] In the above embodiment, culverts body facing the curb block 6 of water collecting window hole 8A, the one side upper A ₁ facing the edge 4a of the 8B water permeability of the road pavement surface 4 of the culvert body 1 and the pavement 5 1 flowing the by forming each of the other side upper a _2, and running water W ₁ flowing permeable layer 4A to form a road paving surface 4, the surface of the road pavement 4 without penetrating into the permeable layer 4A The flowing water W ₂ is collected from each of the water collecting windows 8A and 8B to the flowing water hole 2 in the culvert main body 1 to drain the water, but not shown in the drawing, but is not limited to any one of the culvert main body 1. The present invention is also applicable to a case where water is collected by providing either the water collecting window hole 8A or the water collecting window hole 8B above the side surface.

[0028]

As described above, according to the present invention, a plurality of water collecting window holes for receiving flowing water from a road pavement surface are provided above a side surface of a culvert main body having a flowing water hole in a longitudinal direction of the inside thereof. The running water is efficiently flowed into the culvert main body and drained through the flowing water hole, so that the rainfall is severe and the slipping accident is prevented without flooding the surface of the road pavement even if the rainfall is large. In addition, dirt and dust are less likely to enter the culvert main body, eliminating the need for cleaning, and the opening for collecting water is not formed on the upper surface, so it is sufficiently resistant to external forces such as vehicle weight and earthquakes. Can be structurally robust.
