Introduced from the drain. Generally, a drain port is provided with gratings at regular intervals, or a drain block provided with a drain recess at the side end of the lid block that is in contact with the side wall of the side groove block (Japanese Utility Model Publication No. 50-43).

In this case, as the drainage means, a notch recess is formed at the upper end of the side wall of the side groove block, and a water passage groove is formed below the notch recess of the lid receiving step portion (Japanese Patent Application Laid-Open No. H10-1998).

消される。However, the above first to third embodiments
In the conventional example, since only the water overflowing the upper end of the side wall of the gutter block is drained from the upper surface side of the gutter into the gutter, it is difficult to drain rainwater on the road side and the like. If installed on a pavement road,
It is impossible to drain the permeated water in the permeable layer into the gutter. On the other hand, in the fourth and fifth conventional examples, the notch recess is formed at the upper end of the side wall of the gutter block, so that rainwater and the like on the road side and in the permeable layer drain from the notch recess into the gutter. Thus, the above-mentioned problems of the first to third conventional examples are solved.

る。However, both the fourth and fifth conventional examples have a problem in the amount of drainage. That is, in the fourth conventional example, the rainwater on the road, the permeable layer and the gutter is formed only by the water passage formed in the lid receiving step portion.
In the case of the conventional example, since water is guided into the gutter only by the drain recess formed on the lower surface of the lid block, water cannot be guided from the drain to the gutter when the amount of rainfall is large. The upper surface of the gutter or the road surface may be flooded.

全性の点で問題点がある。Therefore, in the fourth and fifth prior arts, in order to improve the drainage function, the opening area (height × depth) of the cut-out recess is formed to be large. It is also conceivable to make the drainage recess large.
However, as the opening area of the notch recess is increased, the notch recess having a large depth and a large step is opened on the upper surface of the side groove, and the pedestrian's toe, a cane, a stroller, etc. There is a problem in terms of safety for pedestrians, for example, such as the wheels being hooked or tripping over the step.

As a result, when a pedestrian or the like passes over the top surface of the lid block, a striking sound is generated between the two blocks, and especially in places where vehicles frequently pass, the wear and tear gradually decreases, and the durability is extremely short. There is also a problem of becoming.

There has been proposed a lid block in which an opening such as a concave portion is eliminated on the upper surface of the lid block. That is, when the cutout recess is formed at the upper end of the side wall of the side groove block, the side end surface of the lid block facing the cutout recess is inclined downward from the upper surface to the inside downward. There is disclosed a lid drainage groove which is suspended from a substantially vertical direction. Thus, a barrier-free structure in which no gap is formed in a portion where the side wall of the side groove block of the lid block abuts, and it can be said that safety for pedestrians and the like can be secured.

がある。However, in the apparatus shown in FIG. 13 of JP-A-9-242161, since there is no drainage opening on the upper surface of the lid block, rainwater on the road, the permeable layer and the gutters can be obtained. First, the water enters the notch recess first, and then drains from the notch recess through the lid drainage groove into the side groove. Therefore, when the opening area of the notch recess is small, the amount of drainage is extremely reduced, and when the opening area of the notch recess is increased to compensate for the amount of drainage, the opening is large and the height of the notch recess is also large. There is a problem that the size becomes large and a large step occurs, which is far from the object of the invention aiming at barrier-free.

There are various restrictions and certain limitations in providing a structure that can maintain pedestrian safety while maintaining the amount of water introduced. The present invention has been made in view of the conventional problems as described above, and when installed on a road with either ordinary pavement or drainage pavement, it can maintain an excellent drainage function over a long period of time. In particular, it is an object of the present invention to provide a road gutter installation structure that can maintain pedestrian safety while maintaining the conventional drainage amount.

通水溝とそれぞれ対向する位置に設置する構成とした。In order to achieve the above object, a first invention of the present application is a gutter installation structure which is installed at an end of a road and drains rainwater or the like, and has a substantially U-shaped gutter. A block, and a lid block placed on a lid receiving step provided on the upper inside of both side walls of the side groove block. A cutout recess is formed at the upper end of the road side wall of the side groove block, and water is passed through the lid receiving step. Each of the grooves is formed, and at the same time, an L-shaped handle hole having an opening on each of an upper surface, a side surface, and a lower surface is formed at a side end of the lid block on the road side. The opening on the upper surface side and the side surface is installed at a position where the opening on the lower surface side and the opening on the lower surface side face the water passage groove of the side groove block, respectively.

れる導水路で連通されることになる。According to the above construction, the inside and outside of the side groove are provided with a drain port having an opening opening on the upper surface side of the side groove and a side opening communicating with the outside of the side groove through the cutout recess. Is communicated by a water channel formed by an opening having a lower side opening on the lower surface side and a water channel formed in the lid receiving portion of the side groove block.

The rainwater and the like on the upper surface of the gutter are guided from the opening on the upper surface, and the rainwater and the like on the road are guided from the opening on the side surface through the cutout recess. Is drained quickly.

Direction width) and the height of the notch recess can be kept low, and it is possible to make the pedestrian's toe and the like barrier-free, and to improve the drainage function and improve the safety of the pedestrian. Can be secured.

An installation structure of a gutter for installing and draining rainwater or the like, wherein an opening at one end is opened on a road side wall of the gutter block at a position facing the permeable layer, and an opening at the other end is provided for the lid block. A through hole was formed at a position facing the opening on the side surface of the handle hole.

A part of the flooded water and / or the seepage water of the permeable layer is drained by the road gutter according to the first invention, and at the same time, most of the rainwater or the like that has penetrated into the permeable layer passes through the handhole from the through hole to the gutter. Since the water is drained inside, the drainage capacity is improved.

When the opening is covered with the filter, the upper surface of the filter and the upper end surface of the side wall of the side groove block, or the upper surface of the filter and the upper end surface of the side wall of the side groove block and the upper surface of the lid block are flush with each other. It was constituted so that it might become.

In addition, the improvement of drainage function and the safety of pedestrians and the like are further ensured. In addition, it is possible to prevent the pavement aggregate or the like from entering into the side gutter, and at the same time, it is possible to prevent clogging of the handle hole and maintain the drainage function for a long time.
