Description

  The present invention relates to a structure of a curb drainage groove installed on a road or a parking lot, particularly a bridge.

  Conventionally, as the structure of road drainage grooves installed on roads and parking lots, especially bridges, etc., for example, a concrete drainage groove body is laid along the inside of the curb block at the end of the road surface made of asphalt etc. In addition, rain water is collected from the road surface, and at the same time, water that has permeated into the road surface is introduced. In the conventional structure of this kind of drainage groove for road surface, especially when installing on a bridge or the like, it is the mainstream to form the drainage groove main body and curb block etc. with concrete and install them individually. For this reason, not only the production, transportation, and construction work on the site are complicated, but also the weight is increased, and a large-scale civil engineering work is required for repairs and replacements, resulting in problems in terms of construction period and cost.

  By the way, in this kind of drainage groove structure for road surfaces, a curbstone drainage groove in which a curbstone that prevents the automobile from deviating from the road surface and a drainage groove that drains the road surface is integrally formed is known (for example, a patent) Reference 1). The curb drainage groove is formed of a cylindrical main body formed in a substantially L shape, and is provided with a water permeable hole in a horizontal plane of the cylindrical main body so that the horizontal plane has a road surface height. In such a curb drain, the upper part of the substantially L-shaped cylindrical main body is used as a curb and is configured to collect rainwater and the like on the road surface from a water-permeable hole provided in the horizontal plane.

In recent years, there has been a demand for a curb drainage structure that can be manufactured more easily with respect to the curb drainage groove as described above, has excellent water flow function and durability, and has improved inspection and cleaning work efficiency. Yes.

It is integrally formed, and a lattice portion is formed on the front groove portion of the front plate portion, and a lattice lid member is attached to the front groove portion. In addition, water can be efficiently collected in the cylindrical main body or in the front groove, and the water passing function is excellent. 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 a cylindrical body having a curb shape, but also has excellent durability and is a conventional concrete product. Compared with, it is lighter, the workability on site can be greatly simplified, and the construction period can be shortened.

  According to the invention of claim 2, since the lattice lid member is detachably attached to the front groove portion in claim 1, the cleaning device such as a brush is removed by removing the lattice lid member when cleaning the front groove portion. It can be used to remove dust and dirt, and its inspection and cleaning can be performed easily, efficiently and completely. Furthermore, even if the grid lid member of the curb drainage groove is deformed or damaged, it can be easily replaced.

  According to the invention of claim 3, in claim 2, the upper plate portion and the front plate portion of the cylindrical main body are detachably attached to the bottom plate portion and the back plate portion of the cylindrical main body. Thus, each part can be divided and handled lightly, so that the production of the cylindrical main body becomes simpler and the construction can be easily performed even with a small number of people, and the workability is extremely good.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, since the mounting fixing portion is formed on the bottom plate portion and the back plate portion of the cylindrical main body, the curb drainage groove is appropriately disposed. It can be installed easily and reliably at the installation location.

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

  As shown in FIGS. 1 and 2, the curb drainage groove 10 of the present invention is a cylindrical main body having a curb shape comprising a back plate part 13, an upper plate part 14, and a front plate part 16 on a bottom plate part 12. 11 and the front groove portion 20 are integrally formed along the front lower portion 16A of the front plate portion 16. In the curb drainage groove 10, a lattice portion 15 is formed above the front groove portion 20 of the front plate portion 16, and a lattice lid member 30 is attached to the front groove portion 20. In FIG. 2, symbol R is a water-permeable pavement, R1 is a water-permeable layer, R2 is a base layer, M is a soil layer, and B is a curb block.

  The cylindrical main body 11 is formed as a curb shaped frame body by a bottom plate portion 12, a back plate portion 13, an upper plate portion 14, and a front plate portion 16 made of a metal plate such as a steel plate, and an automobile deviates from the road surface. In addition to acting as a curb to prevent this, rainwater and the like collected from the lattice portion 15 and the like which will be described later are drained to an appropriate distribution pipe or the like. Reference numeral 17 denotes a fixing member for the upper plate portion 14, 18 denotes a fixing member for the lattice portion 15, and 19 denotes a water-permeable hole provided in the groove wall portion 12 </ b> A of the bottom plate portion 12.

  The lattice portion 15 is formed on the front plate portion 16 of the cylindrical main body 11 so as to prevent fallen leaves, dust and the like from entering the cylindrical main body 11. Further, as shown in the figure, the lattice portion 15 of the embodiment is configured in a lattice shape including a main member 41 arranged in parallel in the tubular direction of the tubular main body 11 and a reinforcing member 42 orthogonal to the main member 41. However, other structures may be employed. The main member 41 of the embodiment has an I-shaped cross section, and the reinforcing member 42 is a member called torsional steel.

  The front groove portion 20 is formed on the bottom plate portion 12 and is surrounded by the front lower portion 16A of the front plate portion 16 and the groove wall portion 12A of the bottom plate portion 12. Further, the front groove portion 20 is configured such that the upper portion appears on the surface of the road surface (water-permeable pavement portion R), and rainwater collected from the lattice lid member 30 and the water-permeable holes 19 described later is appropriately distributed. Drain to etc.

  The lattice lid member 30 is attached to the front groove portion 20 so that fallen leaves, dust and the like do not enter the front groove portion 20 of the curb drainage groove 10. In this embodiment, as shown in FIGS. 1 to 3, the lattice lid member 30 has a side plate portion 33 that abuts against the mounting portion 21 of the front groove portion 20 and is arranged in parallel in the groove direction of the front groove portion 20. The member 31 and the reinforcing member 32 orthogonal to the main member 31 are configured in a lattice shape. Similarly to the lattice portion 15, the main member 31 has an I-shaped cross section, and the reinforcing member 32 is called a torsion steel. Further, it is preferable that a water permeable portion 34 is formed in the side plate portion 31 at a position corresponding to the water permeable hole 19 formed in the groove wall portion 12 </ b> A of the bottom plate portion 12. The lattice lid member 30 is not limited to this example, and other structures may be adopted.

  Moreover, it is preferable that the lattice lid member 30 is detachably attached to the front groove portion 20 as defined in the invention of claim 2.
