Description

  The present invention relates to a drainage apparatus internal curb stone laid along a boundary between a sidewalk and a roadway.

  In large suburban roads and urban areas of the town, concrete blocks are arranged side by side between the sidewalk and the roadway to define the boundary of the roadway. The concrete block is a rectangular cube with a trapezoidal cross section and is molded from concrete. It is generally called a curb. As a conventional drainage method from the curbstone, there is an L-shaped pedestrian boundary block that directly flows into a water collecting basin provided on the surface of the roadway without flowing into the roadway side. (For example, refer to Patent Document 1) and concrete for collecting and draining water. (For example, see Utility Model Registration Document 1.) There is also a curb that provides a groove on the curb itself to allow rainwater on the sidewalk to flow into the roadway. (For example, refer to Patent Document 2) Similarly, there is a curb that is integrally molded with a drainage curb sandwiched between the curb base and the curb top. (For example, see Utility Model Registration Document 2.)

  As a conventional drainage structure, a grid-like drainage hardware is sandwiched between curbs as shown in FIG. 5 and base concrete is applied to adjust the height, and the left and right sides of the drainage hardware are mortar-packed and fixed. Rainwater, etc. flows into the road surface through the mouth of the lattice mesh.

  Since conventional drainage hardware is mounted manually by humans, there is a risk that it will be pulled out from the upper surface of the curb, and during snow removal work in winter, the drainage hardware gets caught on the blade of the snowplow grader and breaks. It is possible to end up. Moreover, it can be considered that it takes a considerable amount of time to install the drainage hardware.

  Moreover, since the spout for rainwater and the like is flush with the surface of the road, the spout may become clogged with dust, mud, etc. over time, and the role may not be achieved.

  The mouth of the latticed mesh may become clogged with the passage of time, such as cigarette butts, garbage, mud, etc. There is also a risk of losing aesthetics in the landscape.

JP 2000-345508 A Japanese Patent Laid-Open No. 9-177015 [Utility Model Registration Document 1] No. 3071044 [Publication Model Registration Document 2] No. 3097785

  In the current construction method, the conventional drainage hardware is uneven as shown in Fig. 5, and during snow removal work in winter, the drainage hardware gets damaged by the blade of the grader of the snowplow. Has the disadvantage of spending time on. Also, as the years go by, the mouthpiece 24 and the mouthpiece 26 may become clogged with cigarette butts, dust, mud, etc., and may no longer function.

  The present invention is intended to solve such a conventional problem, efficiently attaching a drainage metal fitting, has a constant accuracy and does not have a risk of breakage, and cigarette butts, dust, mud, etc. The goal is to create a curb that will not clog over time.

Means to solve the problem

  In order to achieve the above-mentioned object, the present invention includes the drainage device 3 enclosed in a curb stone in factory production and co-fired into the integrally molded FIGS.

  The second problem-solving means is that the drinking water outlets 24 of the drainage device 3 are provided in the water-permeable layer 17 of the water-permeable pavement 16 on the sidewalk side W using the drinking holes 24 of a conventional mesh of drained metal as a plate material. The thickness of the water permeable layer 17 is provided by adding 5 mm.

  The third problem solving means is that the position of the conventional outlet 26 is flush with the road surface R, and there is a risk of clogging of cigarette butts, dust, mud, etc. In ˜2, the drainage port 4 is provided 13 above the road surface R.

The invention's effect

  As described above, the drainage device internal curb stones 1 and 2 of the present invention are standardized with high accuracy in factory production, and the drainage device 3 of the permeable pavement 16 is simultaneously used in exactly the same way as laying a conventional curbstone. It is possible to provide an innovative drainage device inclusion stone 1 that can be laid and does not require any labor for the drainage device 3.

  Further, since the water intake 5 is provided in the water-permeable layer 17 on the sidewalk side W and the drinking mouth 24 of the conventional grid-like mesh is used as a plate material, it is possible to provide a solution for clogging of cigarette butts, dust, mud and the like.

  The drain outlet 4 and the conventional outlet 26 have the same road surface R, and as time passed, there was a risk of clogging of cigarette butts, dust, mud, etc. So we can provide things that can be solved.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  1 to 4 show a drainage device inclusion stone 1 according to the present invention. The drainage device inclusion curb 1 is integrally molded with the drainage device 3 enclosed in the curbstone.

  There are a pouring method and a bi-con method as a co-pounding integrally molding method of the drainage device FIGS.

  First, a general casting method will be described. The drainage device 3 is placed in a conventional casting curb form. As the direction of insertion, the drainage channel 6 of the drainage device 3 is set as the upper surface, and the drainage port 4 is installed so as to match the inclined surface of the mold. In addition, the length of the drainage device fixing rod 20 is adjusted so that the drainage device fixing rods 20 are exactly in contact with the wall surfaces on both sides of the mold, and the ready-mixed concrete is poured and molded.

  Next, the bicon method will be described. The Bicon method is super hard concrete that is molded by wave vibration and compression compaction with a water / cement ratio of 38% or less. Since considerable vibration and pressure are applied, a foam having a length of 50 mm, a thickness of 6 to 7 mm, and a width of 75 mm is firmly attached and fixed to the left and right sides of the center of the curved surface 19 of the drainage device 3 with gum tape or the like. After that, in the same way as the pouring method, it is attached to the conventional mold frame for bicon curb, injecting super hard concrete, and molding by compaction of wave vibration and compression.

  Next, a method for manufacturing the drainage device 3 will be described. The position of the drainage channel lower part 8 is obtained 30 mm to 50 mm above the curb surface 12 of the curb base 12 and a square pipe is used as the drainage channel pipe. The position of the drainage channel lower portion 8 is provided at the boundary between the water-permeable pavement 16 and the non-water-permeable pavement 18 on the sidewalk side W, and the dimensions of the square pipe are set. The drain port 4 and the intake port 5 of the drainage channel should not protrude from the corner of the curb. Next, the curve center 19 of the drainage device 3 is formed from the intersection of the curb slope surface 12 extending from the road surface R to the curb curve center 2 and the sidewalk side W and the curb stone upper surface boundary 11 to the curb curve center 2 extension line. A dimension is taken so that it may fall 5 mm-6 mm, and the board | plate material of the drainage device surface material 7 is attached from the water intake upper surface 15 to the water discharge upper surface 9 along it. Since a space is formed between the drainage device surface material 7 and the square pipe of the drainage channel, the space is supported by the support rod 14.

  In this embodiment, the material of the drainage device 3 is a steel square pipe, a steel striped steel plate, a steel deformed rebar, and galvanized coating as a rust inhibitor. Other than that, it can be made of stainless steel, aluminum or FRP, and the material is not particular. In addition to square pipes, round pipes can be used as drainage pipes, and the shape and material of the drainage pipes are not particular.
