Description

  The present invention relates to a drainage channel that is installed in a road, a parking lot, or the like, and particularly relates to a metal drainage channel that is buried in a road surface made of permeable asphalt or the like.

  In recent years, a water-permeable pavement formed of water-permeable asphalt or the like has been frequently used in order to improve the drainage of road surfaces such as roads. In such a water-permeable pavement, rainwater or the like on the road surface flows on the upper surface of the road surface and penetrates into the pavement, and is collected and drained in the drainage channel.

  As a structure of this conventional drainage channel, a concrete drainage channel body is laid on the road surface to collect rainwater from the road surface, and at the same time, water that has permeated into the permeable pavement can be introduced. A structure has been proposed (see, for example, Patent Document 1). In this drainage groove structure, a concrete drainage groove main body is disposed along the inside of the curb block at the end of the water-permeable pavement, and the upper surface on the opening side is buried so as to be the road surface height of the pavement. In addition, the drainage groove main body has a receiving step portion on which the end of the water-permeable pavement is laid, and a slit capable of collecting water is provided in the receiving step portion so that rainwater or the like that penetrates into the water-permeable pavement portion can be obtained. It is configured to collect water.

  By the way, in this kind drainage ditch channel, it is inevitable that fallen leaves, earth and sand, garbage, etc. enter and accumulate in the channel, and there is a dislike that drainage becomes worse with long-term use. However, in the case of a drainage channel made of a concrete product that has been widely used in the past, it is impossible or difficult to open the channel for inspection and cleaning. There is no choice but to force water to flow away the earth and sand in the waterway. However, it is difficult to completely remove the earth and sand in the water channel with the momentum of water such as a hose, and there is a limit in efficiency. Further, the cleaning work is complicated.

On the other hand, as for the conventional drainage channel, the concrete products are mainstream as shown above. However, this kind of concrete products is heavy, and the transportation and construction work on site are complicated. On the other hand, large-scale civil engineering work is required for repair and replacement, and there are problems in terms of construction period and cost.
Japanese Patent No. 2849347

  The present invention has been made in view of the above points, and is lighter and more workable than conventional concrete products, is easy to manufacture, has excellent water flow function and durability, and is easy to inspect and clean. A novel drainage channel structure that can be easily and efficiently performed completely is provided.

  That is, the invention according to claim 1 is a mounting method in which a bottom portion is formed in a circular shape or a taper portion, and both ends of the flowing water tube portion in a cylindrical direction and an intermediate portion with an appropriate interval projecting in a circumferential direction. The present invention relates to a drainage ditch channel characterized by comprising a flange, an upper groove portion integrally provided through an opening at the upper part of the water flow tube portion, and a lid member attached to the upper groove portion.

  The invention according to claim 2 relates to the drainage channel according to claim 1, wherein the flowing water cylinder portion is cylindrical.

  According to a third aspect of the present invention, the drainage channel according to the first aspect, wherein the flowing water cylinder portion has a flat plate-like upper plate portion separable from the main body portion, and the upper groove portion is formed in the upper plate portion. Concerning.

  According to a fourth aspect of the present invention, there is provided the drainage channel according to any one of the first to third aspects, wherein the lid member is detachably attached to the upper groove portion.

Since it consists of a collar part, an upper groove part erected integrally through an opening in the upper part of the water-flow cylinder part, and a lid member attached to the upper groove part, the road surface and the water inside are effectively and efficiently used. Water can be well collected in the water pipe section and has excellent water flow function. Moreover, in this structure, since it is made of metal obtained by processing a metal plate, it is not only easy to process including the formation of the flowing water cylinder part, but also has excellent durability, compared to conventional concrete products. It is lightweight, and the workability on site can be greatly simplified, and the construction period can be shortened.

  According to the invention of claim 2, in claim 1, since the flowing water cylinder portion has a cylindrical shape, rainwater collected in the flowing water cylinder portion can be drained more efficiently.

  According to a third aspect of the invention, in the first aspect, the flowing water cylinder portion has a flat plate-like upper plate portion separable from the main body portion, and the upper groove portion is formed in the upper plate portion. Since the flowing water cylinder part can be divided and handled lightly, the manufacturing of the flowing water cylinder part becomes easier and the construction can be easily performed even by a small number of people, and the workability is extremely good.

  According to the invention of claim 4, in any one of claims 1 to 3, since the lid member is detachably attached to the upper groove portion, the lid member is removed when cleaning the upper groove portion. Dust and earth and sand can be removed using a cleaning tool such as a brush, and the inspection and cleaning can be performed easily, efficiently and completely. Furthermore, even if the lid member of the drainage channel is deformed or damaged, it can be easily replaced.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
