DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for drainage pavement of a drainage pavement portion of a road or the like, and a collection / drainage structure in the drainage pavement, and more particularly to a road having a surface layer formed of drainage pavement material. Drainage pavement collecting system for drainage pavement and drainage pavement collection and drainage structure in which a drainage basin is constructed to collect and drain seepage water in place of a collection basin at the installation (and construction) point It is.

[0002]

2. Description of the Related Art In general, a conventional road pavement has a curb or a gutter as a road side, and an intermediate portion thereof is covered with a pavement having a slope in either the center side or the road side for draining the road surface. It is a target.

[0003] The surface layer for directly supporting the vehicle load on such a pavement road is usually formed of a high-density material such as asphalt or cement concrete.

[0004] In this way, the durability of the tire against abrasion and peeling by the tire is maintained, and the road surface water generated by rainfall or snow melting enters the roadbed subgrade by guiding it to drainage means using a cross slope or the like. Is prevented from doing so.

On a road having a surface layer made of a material having a high density such as asphalt or cement concrete, it is inevitable that some surface water remains.

[0006] The residual (stagnant) road surface water not only causes hydroplaning phenomena, slippage, splashing, and smoking phenomena, but these phenomena themselves cause vehicle driving errors and cause traffic accidents. It has been pointed out that it often causes this.

Therefore, recently, a drainage pavement (technique) has been proposed in which the surface layer of a road is formed of a material having a high porosity and rainwater or the like is directly immersed in the surface layer so that road surface water is not generated. Various studies have been conducted for practical use.

As a means for draining permeated water permeated into the surface layer of the drainage pavement, for example, the drainage pavement is located below the drainage pavement surface layer and cut off by a base roadbed made of a material having a high density. To drain to the shoulder,
Alternatively, a method of draining water through a U-shaped groove having water permeability arranged along the road shoulder is adopted.

However, on many urban roads, arterial roads, and highways where the curbs and shoulders are made of concrete structures, the permeated water permeating from the surface layer stagnates in the base roadbed and subgrade, When this accumulated water reaches the surface, not only the function of the drainage pavement body is lost, but also the durability of the road itself is impaired due to a decrease in the support capacity of the basement roadbed and subgrade. Had occurred.

Under these circumstances, a drainable pavement material is laid to a predetermined thickness on a base layer of a road to form a drainable surface layer, and a spiral shaped permeated water drainage pipe is formed along a longitudinal edge of the surface layer. By burying and further connecting the seepage water drainage pipe to drainage means including a catchment basin (or drainage basin),
There is one that quickly and surely drains permeated water that has permeated the surface from the road surface. For example, JP-A-8
-81993 and JP-A-8-93041.

[0011]

However, the above-mentioned known seepage water drainage pipe is deteriorated in permeation function due to clogging of the drainage surface layer with dirt, sand and the like flowing with rainwater over time. Because of the lack of cleaning means, it was necessary to periodically replace it with a new one.

Further, the end (terminal) of the seepage water drainage line is
It was necessary to connect to a catchment basin (or drainage basin) or a gutter, and it was necessary to newly install a drainage facility (means) in a place where there was no drainage facility.

Further, when the permeated water drainage pipe is connected to the gutter, it is necessary to bend the permeated water drainage pipe and connect it.

The present invention has been made in view of such circumstances, and requires a water collecting basin by collecting water from a seepage drainage line via a water collecting device in a gutter parallel to the shoulder side of the road. The present invention proposes a drainage pavement water collecting device and a drainage pavement structure for drainage pavement that are easy to construct and easy to maintain for function maintenance.

[0015]

SUMMARY OF THE INVENTION In order to solve the problem, the present invention relates to a drainage pavement collecting device for collecting and draining permeated water instead of a collecting basin at an installation location, comprising: A steel water collecting structure member connected to the terminal of the water drainage pipe and forming a pipe having a substantially rectangular cross section has a plurality of water holes in the longitudinal direction of the side wall surface of the roadway in contact with the drainage surface layer of the road pavement. And, having a cleaning opening in the upper wall surface included as a free surface in a part of the road surface, and the cleaning opening has an opening and closing lid,
It has a pipe mounting opening to which a drain pipe for communicating with a side groove running parallel to the road shoulder side wall surface can be connected.

Further, in the drainage pavement structure of the drainage pavement mainly including the drainage pavement collecting device for construction, the steel water collection structure member is interposed between terminals of a permeated water drainage pipe. The drainage hole provided in the steel water collecting structure member is placed in contact with the drainage surface layer of the road pavement, a drainage pipe is connected to the pipe mounting opening, and a drainage channel is communicated with a side gutter running in parallel, for cleaning. A drainable pavement material is laid and leveled so that the upper wall surface including the opening and closing lid is included as a free surface in a part of the road surface.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the apparatus of the present invention according to a preferred embodiment, in the above-mentioned steel water collecting structure member, it is preferable that an opening / closing lid of a cleaning opening is an openable / closable sliding door. Further, an optical reflector may be provided on an upper wall surface included as a free surface on a part of the road surface, and a road surface display function for clearly indicating a boundary between a road or the like and a road shoulder at night may be added. Furthermore, while providing a plurality of substantially water-permeable holes in the upper wall surface, in order to adjust the strength and the opening ratio, the opening width or the major or minor diameter of the water-permeable holes in the transverse direction of the arrangement from the roadway side to the shoulder. It may be formed by gradually widening or expanding the diameter.

In the drainage pavement collecting and draining structure (hereinafter, the present invention structure), the infiltration water such as rainwater that has infiltrated the drainage surface layer from the road surface is formed on the upper surface of the base layer of the road pavement. Gradient towards the bottom (shoulder direction)
And flows into the permeate drainage line, and moves within the line. Then, the permeated water flowing through the permeated water drainage pipe is received by the apparatus of the present invention connected to the pipe end, and collected (drained) through a drainage pipe communicating with the gutter.

This makes it possible to replace the catchment basin and extend or branch the seepage water drainage line using the device of the present invention as a terminal (starting point or relay point). The degree increases.

The end of the seepage water drainage pipe is preferably inserted and connected to the open end of the apparatus of the present invention, and the seepage water drainage is discharged from the cleaning opening left as a free surface on a part of the road surface. Since the terminal portion of the pipeline can be pulled out and the air or water can be pumped and cleaned, the maintenance for maintaining the function of the device (the pipeline) becomes extremely easy.
