Description

  The present invention relates to a structure of a road surface drainage groove installed on a road, a parking lot or the like, and more particularly, to a structure of a metal road surface drainage groove embedded 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 through the upper surface of the road surface and penetrates into the pavement, and is collected and drained in the drainage groove for the road surface.

  As a conventional structure of this kind of drainage groove for road surface, a drainage drainage body made of concrete is laid on the road surface to collect rainwater etc. from the road surface and at the same time introduce water that has penetrated into the permeable pavement. The structure which can be performed is proposed (for example, refer patent document 1). In this drainage groove structure, a concrete drainage groove main body is arranged 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 of drainage groove structure, it is inevitable that fallen leaves, earth and sand, dust and the like enter and accumulate in the water passage, and there is a disagreement that drainage becomes worse with long-term use. However, in the case of drainage structures made of concrete products that have been frequently used in the past, it is impossible or difficult to open the water passage for inspection and cleaning. The only way to do this is to pour water and force the soil and sand in the waterway to be forced away. 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 groove structure, concrete products are mainstream as shown above, but this kind of concrete products are heavy, and 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

Water can be well collected in the groove member and has excellent water flow function. In addition, this structure is made of metal processed metal plate, so it is not only easy to process including the formation of water permeable parts, but also has excellent durability and light weight compared to conventional concrete products. Therefore, workability on site can be greatly simplified and the construction period can be shortened.

  In addition, according to the structure of the drainage groove for metal road surface, since the upper part of the groove member and the lid member are constituted by separate members, each member can be divided and handled lightly, so that a small number of people can be handled. But construction is easy. Further, when a flow channel having a predetermined gradient is formed in the groove member with concrete or mortar (invert gradient) in the field construction, workability is extremely good because the entire upper surface is opened.

  Furthermore, if it is set as the structure by which the water permeable part was provided in the said wall part, the rain water etc. which permeate | transmitted in the water-permeable pavement part can be introduce | transduced into a water flow part more effectively.

  Furthermore, since the lattice member is detachably provided at the upper part of the buttock portion, when cleaning the groove member, the lattice member is removed and dust or earth and sand are removed using a cleaning tool such as a brush. The inspection and cleaning can be performed easily, efficiently, and completely. Furthermore, in the unlikely event that the lattice member constituting the upper surface of the drainage groove is deformed or damaged, it can be easily replaced. Furthermore, since the lattice part is fitted to the collar part via a spring clip, a constant gap for water flow is formed between the lid part and the collar wall part of the collar part, and Both can be elastically press-fitted and held without rattling.
