  In the drainage groove structure of Patent Document 1 described above, since the water passage portion that guides the water permeability of the water permeable surface layer from the outer periphery of the drainage groove to the inside is a porous form that penetrates the fine gap, The through water permeability is not good, and the water permeability and drainage from the water permeable surface layer of the road is inferior. And since the water flow part is structurally weak and has a weak mechanical strength, it has a strength problem as a large groove road crossing groove that receives a repeated load of a passing vehicle.

  On the other hand, since the drainage channel structure of the cited document 2 is a structure in which a water passage hole is provided in the side wall of the drainage channel body, a drop between the water flow from the water passage hole and the water flow of the drainage channel body cannot be secured. There is a case and water drainage is inferior. And since it is a steel plate-like groove body structure, there exists a restriction | limiting on intensity | strength and there exists a malfunction which is hard to use as a road crossing groove | channel which receives the repeated load of a passing vehicle.

  The present invention solves the above-mentioned problems of the background art, and provides a road concrete groove that is lighter than a conventional concrete groove and can be used widely as a road side groove / road crossing groove.

  The concrete groove for roads of the present invention that solves the above technical problems is composed of a groove body of a U-shaped concrete groove and a metal drainage body mounted and fixed in the longitudinal direction of the upper end of the side wall of the groove body. The drainage body has an L-shaped lower side front end opened to the inside of the groove main body, an inner L-shaped recess is formed in the groove lid mounting portion, and a water hole group is densely formed in the back plate portion. It is characterized by a structure in which the back plate is joined to a water-permeable surface layer of a paved road in the form of a hollow L-shape formed.

  That is, the road concrete groove according to the present invention having the above-described configuration is constituted by a combined connection structure of a concrete U-shaped groove main body and the drainage body mounted and fixed on the upper end of the side wall of the groove main body. It is characterized by the idea of a combined structure according to function that ensures a sufficient water flow difference between the drainage body and the groove main body, and also ensures the mechanical strength necessary as a road groove by the groove main body made of concrete.

  And as a form of the basic configuration, “a form in which the drainage body is continuously disposed in the longitudinal direction of the upper end of the groove body or a form in which the drainage body is intermittently disposed”, “a part of the road surface is formed in the facility state on the road” A form in which a water hole for road surface water is provided on the upper surface of the water drainage body to guide the road surface water and drop it down is adopted.

  Further, the connecting and fixing means for the drainage body and the groove main body are “an anchor bolt embedding means provided on the drainage body”, “bolt fastening fixing means by a connecting plate”, and “a nut pocket for connection on the upper surface of the drainage body” And a connecting bar with a turnbuckle that is set between the drainage bodies disposed opposite to each other. The “coupling fixing means” or the like is adopted.

  The concrete groove for roads of the present invention having the above-described configuration is a vertically arranged structure according to function of a drainage body that introduces water permeability by joining to a water permeable surface layer of the road and a groove body of a drainage mainstream function of the groove body. Therefore, the water flow difference between the two is sufficiently stable, and the water flow / collecting / draining action of the water drainage body is extremely good and stable.

  And since the groove main body is made of concrete, it is possible to ensure the shape size and strength according to the application and function, and it can be used widely as road crossing grooves and road side grooves.

  And, in the above-mentioned aspect, what is provided with a "water passage hole for road surface water on the upper surface of the water drainage body" collects and drains road surface water such as rain water from the water flow hole and flows down into the groove main body, Good road surface water drainage can be secured.

  Hereinafter, with reference to FIGS. 1-4, the preferable Example of the concrete groove | channel for roads of this invention is described.

  First, FIG. 1 and FIG. 2 show an embodiment of a road concrete groove 1 (hereinafter simply referred to as a concrete groove 1) of the present invention applied as a road crossing groove. On the flat upper end surface 5 of the opposite side wall 4 of the groove main body 2, a steel drainage body 3 continuously extending in the longitudinal direction of the side wall 4 is placed and fixed so as to face a pair of symmetry. The combined structure of the drainage bodies 3 is configured.

  Specifically, the groove body 2 is a normal U-shaped concrete groove formed at a groove height H2 obtained by subtracting the height H1 of the water drainage body 3 from a predetermined groove height H. (See FIG. 1 (B)) The cross-sectional shape is a hollow L-shaped long body, and includes a drainage port 9 having an opening at the front end between the hollow L-shaped inner bottom plate 6 and the outer bottom plate 7. An inner recess is formed in the groove lid mounting portion 8 for fitting the side edge portion of the groove lid 20 and placing and setting it on the inner bottom plate 6.

  The rear plate 10 of the water drainage body 3 is provided with a small diameter (approximately 6 mm diameter in the present embodiment) of water passage holes 11 (see FIG. 2). The rear plate 10 of the one drainage body 3 is arranged by being joined to the water permeable surface layer 21 of the road R, and is constructed and constructed on the road R so as to function as a road crossing groove.

  The standard size of the concrete groove 1 in this embodiment is “the height H2 of the groove body 2 = approximately 325 to 425 mm, the height H1 of the drainage body 3 = approximately 140 mm, and the groove width B = approximately 410 to 420”. In accordance with the dimensions of the heel, the water drainage body 3 and the groove main body 2 are combined and fixed by fixing means for embedding the anchor bolts 12 provided on the bottom surface of the water drainage body 3 in the groove main body 2.

  And in the upper surface of the water drainage body 3 of this embodiment, many road surface water passage holes 11A through which the road surface water WA of the road R is dropped are formed.

  Reference numeral 13 in the figure denotes reinforcing ribs arranged at a required pitch between the inner bottom plate 6 and the outer bottom plate 7 of the drainage body 3 in order to ensure the mechanical strength of the drainage body 3. Reference numeral 14 denotes a front plate of the outer bottom plate 7.

  The above-mentioned concrete groove is constructed by mass-producing and connecting the groove body 2 and the drainage body 3 to the road site and carrying it on the road site or constructing the factory mass-produced drainage body 3 locally. It is constructed at a predetermined position on the road R by a construction method in which the groove body 2 is formed and solidified by placing the concrete in the concrete form 2 and then casting the concrete.

  The concrete groove 1 of the above embodiment has the above-described action. That is, the water permeability W of the water permeable surface layer 21 by the road surface water WA of the road R naturally flows from the water passage hole 11 of the water drainage body 3 to be joined, and is introduced into the hollow portion of the water drainage body 3 to be drained. The water drains naturally and merges with the main drainage in the groove body 2 to collect and drain the water very effectively.

  Furthermore, since the thing of this Example has 11 A of water passage holes for road surface water in the upper surface of the water drainage body 3, for example, the groove | channel cover 20 of the road R in the case of a concrete lid inferior to the water drainage property of the road surface water WA. Effectively collects and drains road surface water WA.

  And the mechanical strength of the whole concrete groove | channel 1 can be ensured by forming the drainage body 3 in the form of required mechanical strength, and it can function as a concrete groove | channel with favorable drainage performance.

  And since the concrete groove 1 is a united structure of the lightweight drainage body 3 and the concrete groove body 2, the whole is lighter than the concrete groove of the same size of concrete quality, and the above-mentioned factory mass-produced product is installed locally. There is a secondary effect that makes the construction method easier.

  Next, another embodiment of the concrete groove 1 of the present invention will be described with reference to FIG. That is, in the structure having a combination fixing structure of “groove body 2 and drainage body 3” similar to the embodiment in FIG. 1, the structure shown in FIG. It is in the form of being intermittently arranged in the longitudinal direction and fixed in combination.

The thing of this Example can also enjoy the effect similar to FIG. 1 Example.

  Next, with reference to FIG. 4, the other form of the connection fixing means of the groove main body 2 and the drainage body 3 of the concrete groove 1 of this invention is demonstrated. That is, first, what is shown in FIGS. 4 (A) and 4 (B) hangs down the drainage body 3 through the “connection plate 22 to be joined to the side wall 4 of the groove body 2”, and the connection plate 22 is bolted to the side wall 4. It consists of connecting and fixing means. In addition, the connection means by this connection plate 22 may be only the connection plate 22 joined only to either the inner surface or the outer surface of the side wall 4, and may be used in combination with the anchor bolt 12 fixing means.

  4 (C) is provided with a connecting nut pocket 24 that opens on the upper surface of the drainage body 3, and a connecting bolt 23 that is fixed to the side wall 4 of the groove body 2 and extends upward is provided in the nut pocket 24. It consists of a connecting and fixing means that protrudes and fastens with a nut.

  4 (D) shows a fixing plate 26 that is suspended from the lower edge of the drainage port 9 of the pair of drainage bodies 3 disposed opposite to each other and joined to the inside of the side wall 4, and the fixing plate 26. A “fixing bar 25 with a turnbuckle 27” provided between them is provided, and the fixing plate 25 is strongly fixed to the side wall 4 by the fixing bar 25 so as to be connected and fixed.

  The above connection fixing means can function effectively as a road groove body by accurately connecting and fixing the groove body 2 and the drainage body 3 together. And since the connection means of FIG.4 (C) (D) becomes the detachable form which can remove the drainage body 3 from the groove | channel main body 2 constructed | assembled to the road R, the concrete groove 1 whole containing the drainage body 3 is used. The maintainability is improved.

  In addition, the concrete groove 1 of the present invention is not limited to the above-described embodiment. For example, when a grating (a rectangular lattice-shaped groove cover) that is excellent in drainage performance of the road surface water WA is used as the groove cover 20, water for road surface water flow is used. The hole 11A may be absent or the front hanging plate 14 may be omitted. Furthermore, in the case of a road configuration in which the water permeable surface layer 21 is present only on one side of the concrete groove 1 such as a road side groove, In some cases, the drainage body 3 is made absent to form a normal concrete wall, or the water passage hole 11 of the drainage body 3 on the absence side is made to be absent.
