Description

  The present invention relates to a road drainage channel embedded in a road surface such as a sidewalk, a road, and a parking lot.

  In order to improve drainage of road surfaces such as roads, permeable pavement made of permeable asphalt or the like is used. According to this water-permeable pavement, rain water or the like can flow on the road surface, and rain water or the like accumulated on the road surface can be permeated into the interior to be drained to a road drainage channel.

  Conventionally, the road surface drainage channel 80 of patent document 1 shown to (a) of FIG. 13 is known. In the road surface drainage channel 80, a drainage channel 71 is provided in a pipe-shaped side groove 80 a, and a water flow channel 72 for guiding rainwater is provided in the drainage channel 71. The water flow path 72 collects rainwater that has penetrated into the permeable pavement R, rainwater that has flowed from the surface of the road surface, and the like so that it can be guided and drained into the drainage path 71.

  However, since the pipe gutter side groove 80a is made of concrete, it is very heavy to install on the road surface because a heavy machine or the like is used. Further, since the pipe-shaped side groove 80a is configured to surround the drainage channel 71 with concrete, the size of the road surface drainage channel 80 itself is larger than the drainage channel 71, and a large groove is dug for installation. I had to.

  Then, the road surface drainage channel 90 of patent document 2 shown in FIG.13 (b) whose weight of the road surface drainage channel is light and is easy to install is known. The drainage channel 90 for the road surface is embedded in the road surface and has a substantially inverted U-shaped cross section having an opening on the upper surface, and is opposed to the inner surface of the side surface portion 81a of the main body 81 attached to the opening of the main body 81. The cover member 82 includes a wall portion 82a. In actual installation, it is only necessary to fit the lid member 82 into the bag main body 81 embedded in the road surface so as to be integrated.

  Further, since the upper surface of the lid member 82 is a lattice-like member 85, it is possible to prevent dust and the like from entering the bag body 81 and a tire such as a bicycle from being caught, and to pass rainwater or the like. A large number of water passage holes 83 are provided in the side surface portion 81 a of the heel body 81, and rainwater that has permeated into the permeable pavement can be collected and drained into the heel body 81.

  However, when the lid member 82 is attached to the jar body 81, the water passage section of the jar body 81 is narrowed by the lid member 82 and the lattice-like member 85, and the drainage capacity is reduced. Here, the water flow cross section is a cross section through which drainage can flow inside the main body 81, and in FIG. 13B, the inner side of the main body 81 having a substantially inverted U-shaped cross section and the lid member 82. And a range surrounded by the lower surface of the lattice member 85.

  Then, the drainage channel 100 for road surfaces of patent document 3 shown to (c) of FIG. 13 is known. The road surface drainage channel 100 includes a water flow portion 91 serving as a drainage channel and a collar portion 92 that collects rainwater and the like inside the drainage channel. And the water flow part 91 consists of the bottom part 91a, the back wall part 91b, the front wall part 91c, and the upper wall part 91d, and the collar part 92 consists of the upper end and the side wall 92a of the back wall part 91b. Further, the collar portion 92 is provided with a detachable grid-like lid portion 95. Thus, since the collar part 92 which collect | recovers rainwater from a road surface and guides it to the water flow part 91 is provided in the upper surface of the water flow part 91, the water flow cross section inside the water flow part 91 is ensured. .

  Each member (the water flow portion 91, the flange portion 92, etc.) is formed by cutting and bending a metal plate such as a steel material (for example, the bottom portion 91a of the water flow portion 91 is processed into a U-shape). Is done. And the drainage channel 100 for road surfaces is formed by welding and assembling each member.

  However, the road surface drainage channel 100 is composed of a plurality of members obtained by processing a metal plate such as a steel plate, and there are many steps for welding and assembling. Therefore, the manufacturing cost is increased accordingly, and errors are likely to occur. For example, the drainage in the water passage portion 91 that is a drainage channel may leak to the outside, or the lid portion 95 may not fit into the flange portion 92.

  On the other hand, there is a road surface drainage channel 200 of Patent Document 4 shown in FIG. 14 using a standard square steel pipe without performing sheet metal processing like the road surface drainage channel 100. The road surface drainage channel 200 is configured to open a groove 193 in a standard square steel pipe 191 and drain rainwater and the like flowing into the groove 193 from the road surface. Thus, the simple structure of opening the groove 193 in the square steel pipe 191 using a standard product can secure a water passage cross section and reduce the weight. Furthermore, it describes the advantage that “the use of a square steel pipe, which is a JIS standard, makes it a nationwide standard and can be produced at low cost”.

  However, the road surface drainage channel 200 has a structure in which a standard square steel pipe 191 is provided with a groove 193 and is insufficient in strength. That is, when a vehicle or the like is mounted on the road surface drainage channel 200 embedded in the road surface, such a structure does not have sufficient strength to support its weight.

  Furthermore, by simply opening the groove 193 in the square steel pipe 191, only the rain water flowing toward the groove 193 can be passively passed through the square steel pipe 191. Therefore, rainwater from the periphery of the road surface drainage channel 200 cannot be reliably guided into the square steel pipe 191 and the water collection efficiency is low.

  In addition, in the road surface drainage channel 200 having a structure in which a groove 193 is simply opened in a standard steel pipe 191, even if an attempt is made to change the structure or shape of the road surface drainage channel 200 according to the surrounding situation, Only the size and number are changed, and it is not possible to design for any use mode.

  In this regard, in the conventional road drainage channel 100 (see FIG. 13 (c)), in order to adapt to any use mode, there are a plurality of structural members (through-passage) when trying to change the structure and shape of the road drainage channel. The design of the water part 91, the collar part 92, etc.) is inevitably changed, and the cost becomes very high.

Japanese Patent Application No. 10-347031 Japanese Patent Application No. 2003-283684 Japanese Patent Application No. 2003-110328 Japanese Patent Application No. 10-225134

  Therefore, in view of the above problems, the present invention takes advantage of using a standard steel pipe as in the past, has high water collection efficiency, can flexibly cope with various usage modes, has few components, and is strong in strength. The purpose is to provide a road drainage channel at a low cost.

  The road surface drainage channel of the present invention is a road surface drainage channel using a standard steel pipe for the drainage channel, where a water passage hole is provided on the upper surface of the standard steel pipe and a water passage hole is provided on the side surface. There is a case where it is not provided, and it is characterized by comprising a water guide auxiliary member configured to efficiently guide the drainage from the road surface into the steel pipe through the water passage hole on the upper surface.

  According to the above feature, rainwater or the like from the road surface can be efficiently guided and drained into the steel pipe through the water passage hole by the water guiding auxiliary member. For example, in the case of the road surface drainage channel 10 shown in FIG. 2, the water guide plate 2, which is a pair of water guide aids provided on the upper surface of the steel pipe 1, serves as a water guide auxiliary member, and drains water from the road surface through the water holes 4. It can be efficiently guided to the steel pipe 1 and has high water collection efficiency. Further, in the case of the road surface drainage channel 70 shown in FIG. 6, the upper plate 65 having the water passage hole 63 and having the surface inclined toward the water passage hole 63 serves as a water guide auxiliary member, and drains water from the road surface. Water is collected using the slope, and can be efficiently guided to the steel pipe 61 through the water passage hole 64, so that the water collection efficiency is high. The water transfer auxiliary member may be any member that collects rainwater from the road surface and can reliably drain the collected rainwater to the steel pipe through the water passage hole. It can be a shape. Moreover, the raw material of a water conveyance assistance member, a water conveyance assistance tool, and an upper board can be made into arbitrary materials, such as steel materials and an acrylic board.

  Moreover, since the road surface drainage channel of this application is a structure which consists of a standard steel pipe and a water conveyance auxiliary member, compared with the structure of the conventional road surface drainage channel 200 shown in FIG. 14, strength is strong. For example, in FIG. 2, the strength of the road drainage channel 10 as a whole is improved by providing the standard steel pipe 1 with the water guide plate 2 as a water guide auxiliary member. Moreover, in FIG. 6, the intensity | strength of the whole drainage channel 70 for road surfaces improves by providing the upper plate 65 as a water conveyance auxiliary member in the steel pipe 61 of a standard product.

  Furthermore, the road surface drainage channel of the present application can flexibly cope with various usage modes only by changing the shape of the standard steel pipe or the shape of the water guide auxiliary member. For example, when away from the surface of the road surface to the steel pipe, as shown in FIG. 3, a pair of water guide plates (2, 12) are used as water guide auxiliary members, and the drainage from the road surface is drained into the steel pipe (1, 11). Can be guided to. On the other hand, when the road surface and the steel pipe are close to each other, as shown in FIG. 7, as a water guiding auxiliary member, an upper plate 65 having a water passage hole 63 and having a surface inclined toward the water passage hole 63 is used. The drainage from the road surface can be guided into the steel pipe 61. If the shape of the road drainage channel is to be changed according to the curvature of the road surface as shown in FIG. 5B, the road drainage channel 60 is configured using a curved standard steel pipe 51. You can also.

  On the other hand, if the conventional drainage channel for road surface 100 is intended to change its shape according to various usage modes, the cost becomes very large, and since there are many manufacturing processes, errors are likely to occur. It is possible that the drainage water in the water passage portion 91 leaks to the outside, or the lid portion 95 does not fit into the flange portion 92.

  As described above, the road drainage channel of the present application can flexibly correspond to various usage modes only by changing the shape of the standard steel pipe or the shape of the auxiliary water guiding member, and the component parts are also included. Since there are few standard steel pipes and water transfer auxiliary members, the manufacturing cost is low.

  Here, the standard steel pipe is also used for applications other than the drainage channel for road surfaces, for example, a simple steel pipe such as a raw ERW steel pipe or a seamless steel pipe, and its cross section is square, rectangular, A cylindrical shape such as a circle. In addition, the water passage hole includes an arbitrary shape such as a circular shape, an oval shape, or a rectangular shape.

  Next, the road surface drainage channel of the present invention is a pair of water guiding aids provided in the steel pipe so as to sandwich the water passage hole on the upper surface of the standard steel pipe, and further, water is passed through the side surface of the water guiding aid. It is characterized by providing or not providing holes.

  According to the above feature, the pair of water guiding aids are provided so as to sandwich the water passage hole on the upper surface of the steel pipe, and drainage from the road surface is efficiently guided and drained into the steel pipe through the water passage hole. I can do it. Moreover, when the water flow hole is provided in the side surface of the water guiding aid, rainwater that has permeated into the permeable pavement can also be collected.

  Next, the road drainage channel of the present invention is characterized in that the water guide auxiliary member is an upper plate having a water passage hole, and the surface of the upper plate is inclined toward the water passage hole. It is said.

  According to the above feature, the drainage from the road surface is efficiently guided into the steel pipe through the water passage hole by providing the upper plate whose surface is inclined toward the water passage hole as the water guide auxiliary member. I can do it.

  As described above, according to the road drainage channel of the present invention, while utilizing the advantages of using a standard steel pipe as in the past, water collection efficiency is high, and it can flexibly respond to various usage modes, and the component parts A road surface drainage channel that is small and strong can be provided at low cost.

B Curb U Subbase X Cut surface
Y anchor

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1A shows a front view of the road surface drainage channel 10. It turns out that the water guide plate 2 is protrudingly provided by the upper part of the steel pipe 1 as a pair of water guide auxiliary tools. The water guide plate 2 is provided with water passage holes 3 and rib plates 2a at regular intervals. The water passage hole 3 can collect rainwater that has permeated from the permeable pavement and drain it into the steel pipe 1. The rib plate 2 a is welded to the steel pipe 1 in order to maintain the uprightness of the water guide plate 2. In addition, a long plate-like anchor Y is provided on the lower surface of the steel pipe 1 and is appropriately used for fixing the steel pipe 1 inside the road surface.

  A socket 1b and a connecting pin 2b are provided at the left end of the drainage channel 10 for road surface. The socket 1b is connected to the right end of the road surface drainage channel 10 (the side on which the socket 1b and the connecting pin 2b are not provided). Moreover, since the connection hole 2c which inserts the connection pin 2b is provided in the location which respond | corresponds, the operation | work which connects and constructs the road surface drainage channel 10 can be made easy. In addition, even if it does not provide the connection pin 2b and the connection hole 2c, it can fully perform a connection operation | work and is provided arbitrarily.

  FIG. 1B is a plan view of the road drainage channel 10. It can be seen that a plurality of water passage holes 3 are provided on the upper surface of the steel pipe 1. Moreover, the water guide plate 2 which consists of two parallel plates is provided so that the water flow hole 4 extended to a longitudinal direction may be pinched | interposed into the upper surface of the steel pipe 1, and rainwater flows between this water guide plate 2, and a water flow hole Rainwater can be drained into the steel pipe 1 through 4. Further, a plurality of middle plates 2d are provided between the parallel plates of the water guide plate 2, and the connecting pin 2b is connected to the left-side middle plate 2d (2) on the left-side middle plate 2d (1). Is provided with a connecting hole 2c. Moreover, although it is arbitrary, when connecting the said road surface drainage channel 10, it uses a bolt etc. so that the hole Ya of the anchor Y of each adjacent road surface drainage channel 10 and the long hole Pa of the connection plate P may be penetrated. If it fixes, the adjacent drainage channel 10 for road surfaces can also be connected and fixed more strongly.

  FIG. 1C is a side view (right side surface) of the road drainage channel 10. It can be seen that a water guide plate 2 protrudes from the upper portion of the steel pipe 1. Moreover, since there is no protrusion inside the steel pipe 1, there is nothing which inhibits the flow of the waste_water | drain in the steel pipe 1, and the water flow cross section assumed in the design stage can be ensured.

  FIG. 1D is an enlarged view of the periphery of the water guide plate 2. The lower end of the water guide plate 2 is welded to the upper surface of the steel pipe 1. Further, the rib plate 2a is welded to the parallel plate 2 (1) of the water guide plate 2, and the uprightness is maintained. Since the parallel plate 2 (2) is coupled to the parallel plate 2 (1) by the intermediate plate 2d (2), the uprightness can be maintained. A connecting hole 2c is provided in the center of the intermediate plate 2d (2) so that the connecting pin 2b can be inserted.

  Next, in FIG. 2, the manufacturing process of the road surface drainage channel of the present invention will be described.

  FIG. 2A shows a steel pipe 1 which is a drainage channel portion of the road surface drainage channel 10 of the present invention. The steel pipe 1 is not processed separately except that a standard product is used as it is and cut into a desired length. The steel pipe 1 is preferably 1 m to 6 m long.

  In FIG. 2 (b), the water pipe 3 and the water hole 4 are provided in the steel pipe 1. It is conceivable that the water passage hole 3 and the water passage hole 4 are formed by various methods. However, if a return to the inside of the steel pipe 1 occurs, the flow of the drainage in the steel pipe 1 becomes an obstruction factor. Laser processing that does not occur is desirable.

  Moreover, the magnitude | size of the water flow hole 4 can be taken arbitrarily according to the objective. For example, if the road surface drainage channel 10 is installed in a place where there is little rainfall, it is conceivable to make the water hole 4 small. If it is installed in a place where there is a lot of rain, the water hole 4 is It is possible to enlarge it. And what is necessary is just to change suitably the magnitude | size, the number, and position of the water flow hole 3 provided in the number of the water flow holes 4 and the steel pipe 1 upper surface by the installation place.

  In FIG. 2 (c), two parallel plates 2 (1) and 2 (2) constituting the water guide plate 2 are prepared as a pair of water guide aids. The middle plate 2d welds two parallel plates to determine the interval between the two parallel plates. It can be seen that the water passage holes 3 are provided at regular intervals on the parallel plate 2 (1) side. Moreover, the water flow hole 3 can be arbitrarily provided in the parallel plate 2 (2) side. Since rainwater passes through the inside of the water guide plate 2 and is guided into the steel pipe 1 through the water passage hole 4, the interval between the two parallel plates needs to be equal to or larger than the width of the water passage hole 4. .

  In FIG. 2D, the water guide plate 2 is attached to the upper surface of the steel pipe 1 by welding. The lower end of the water guide plate 2 and the upper surface of the steel pipe 1 are firmly attached by welding, and the uprightness is maintained by welding the rib plate 2a.

  As described above, the process of manufacturing the road surface drainage channel 10 of the present application is performed by cutting a standard steel pipe into a desired length to provide the water passage hole 3 and the water passage hole 4. It is only to weld the pair of water guide plates 2 so as to sandwich the water guide auxiliary member. Thus, by setting it as the structure attached to a steel pipe by welding a water guide auxiliary member, the whole intensity | strength of the drainage channel 10 for road surfaces improves compared with the intensity | strength of a steel pipe single-piece | unit. Moreover, like the drainage channel 100 for road surfaces of patent document 3 (refer to (c) of FIG. 13), a plurality of members such as the water flow portion 91, the flange portion 92, and the lid portion 95 are cut and bent. There is no need to weld and assemble each member, and the manufacturing operation becomes much easier, and the manufacturing cost can be reduced.

  Moreover, when it is the drainage channel 100 for road surfaces, when changing drainage amount (water flow cross section), it is possible to make the width | variety of the bottom part 91a and the height of the back wall part 91b large or small, but in that case, The dimensions of each member such as the front wall portion 91c and the upper wall portion 91d must be changed according to the width of the bottom portion 91a. For this reason, it is necessary to separately prepare a mold or the like for forming each member and to change the design of each member, which increases costs.

  However, in the case of the road surface drainage channel 10 of the present application, when the amount of drainage is changed, it can be dealt with only by changing the size (inner diameter) of the standard steel pipe 1, and other design changes are required. Therefore, the advantage of the standard steel pipe that the cost does not increase can be utilized.

  Furthermore, when it is desired to form a long road drainage channel, in the road drainage channel 100 of Patent Document 3, the longer the length, the lower the processing accuracy of each member, and the more likely the warpage and distortion occur. When assembling, it may happen that it cannot be assembled properly due to dimensional errors. For example, if the drainage leaks from the water passage portion 91 or there is an error in the dimensions of the flange portion 92, the lid portion 95 may not fit.

  However, the road surface drainage channel 10 of the present application does not cause the above problem because the standard steel pipe 1 is used. Further, even if a dimensional error of the water guide plate 2 occurs, it cannot be attached to the steel pipe 1, thereby preventing rainwater or the like from being guided into the steel pipe 1.

  Therefore, the road surface drainage channel 10 of the present application is suitable for being formed into a long shape. When the long road surface drainage channel 10 is used, when the road surface drainage channel 10 is installed on the road surface, the road surface drainage channel is connected. Therefore, it is possible to take advantage of the standard steel pipe that the construction period can be shortened and the construction cost can be reduced.

  (A) of FIG. 3 has shown the use aspect which installed the drainage channel 10 for road surfaces of this application in the road surface. The road surface drainage channel 10 is a side end of the water-permeable pavement R, and is embedded in a foundation crushed stone or foundation concrete U along the curb B. The surface of the water-permeable pavement R is slightly inclined toward the upper end port 2e. The upper end 2e of the water guide plate 2 is located on the same plane as the surface of the surface layer R, and rainwater flows on the surface of the surface layer R. 1 is reliably guided into the interior. As can be seen from FIG. 2 and FIG. 3 (a), the opening area of the upper end 2e of the water guide plate 2 provided so as to sandwich the water passage hole 4 is larger than the opening area of the water passage hole 4. More rainwater can be collected efficiently than the amount of rainwater that can be collected only from the water holes 4. All the collected rainwater is reliably guided to the water passage 4 by the water guide plate 2 and drained into the steel pipe 1. Thus, the road surface drainage channel 10 efficiently guides and drains rainwater from the road surface through the water holes 4 into the steel pipe 1 by the water guide plate 2, and thus has high water collection efficiency.

  Further, since the water-permeable pavement R is paved so as to cover the upper surface of the steel pipe 1 from the side surface of the water guide plate 2, rainwater that has permeated into the water-permeable pavement R enters the steel pipe 1 from the water passage hole 3. It can be drained. Furthermore, since the water passage hole 3 on the upper surface of the steel pipe 1 and the water passage hole 3 on the side surface of the water guide plate 2 are both located at the upper part of the steel pipe 1, the drainage flowing through the steel pipe 1 does not flow backward. Moreover, although the space | interval of the two parallel plates of the water guide plate 2 is arbitrary, for example, about several centimeters in which a heel wrinkle, dust, etc. do not enter are desirable.

  (B) of FIG. 3 has shown the use aspect which installed the drainage channel 20 for the road surface which protruded the water flow board 12 near the near side of the steel pipe 11 in the road surface. Thus, the curb B can be positioned on the upper surface of the steel pipe 11 by changing the projecting position of the water guide plate 12. Therefore, in FIG. 3A, the width L1 occupied by the curb B and the road surface drainage channel 10 can be narrowed as L2 in FIG. 3B, and the space can be effectively utilized. it can.

  The height of the water guide plate 12 in FIG. 3B is set higher than that of the water guide plate 2 in FIG. Moreover, the space | interval of the two parallel plates of the water guide plate 12 of FIG. 3B, ie, the width of the water guide plate 12, is set narrower than the water guide plate 2 of FIG. Thus, since the water guide plate (2, 12) has a simple configuration in which two long plates are provided in parallel, the water guide plate according to the surrounding situation where the road drainage channel is installed. The protruding position, height, and width of (2, 12) can be arbitrarily changed. Moreover, although the water guide plate (2, 12) has installed the elongate board continuously, you may install a short board intermittently.

  Although FIG. 3 shows a case where the water-permeable pavement R is used, it is needless to say that the road surface drainage channel of the present application can be used even on a water-impermeable pavement that does not have water permeability. In that case, since rainwater does not permeate inside the paved road, it is not necessary to provide water holes (3, 13) on the side surfaces of the water guide plates (2, 12) and the upper surface of the steel pipes (1, 11). Therefore, rainwater that has flowed on the surface of the impermeable pavement is collected only from the upper end (2e, 12e).

  FIG. 4A shows a case where the road surface drainage channel 30 is installed on a sidewalk, an external structure, or the like. On a sidewalk or the like, there is a case where a block-type paving material (interlocking block) I1 shown in FIG. Thus, if the height of the water guide plate 22 is adjusted in accordance with the height H1 of the block-type pavement material I1, the upper end 22e of the water guide plate 22 and the pavement material I1 have no step and are positioned on the same plane. can do.

  In FIG. 4B, a standard pavement I2 different from the pavement I1 is used, and the height is H2 lower than H1. Then, the height of the water guide plate 32 of the road surface drainage channel 40 is changed to match the height H2 of the pavement material I2. Thus, since the water guide plate (22, 32) has a simple configuration in which two long plates are provided in parallel, it can be seen that the height can be easily changed. Of course, the width and the protruding position of the water guide plate can be changed as appropriate.

  There are a wide variety of standard pavement materials that are actually used on sidewalks and exterior parts, etc. However, in the case of the road drainage channel of this application, it is possible to respond by simply changing the height of the water guide plate. The cost is not high and it is very useful.

  In FIG. 4, the road surface drainage channel is installed in a straight line, but it is considered that the road surface drainage channel is installed when the road surface is curved as seen at an intersection or the like. In the conventional drainage channel 100 for the road surface of Patent Document 3, a mold for forming each member (water flow portion 91, eaves portion 92, lid portion 95, etc.) is prepared separately in accordance with the curvature of the road surface, Each member was cut and bent. Furthermore, each member must be assembled by welding, which is costly and inefficient.

  Therefore, in the present application, a long road drainage channel formed in a straight line is prepared in advance. Then, as shown in FIG. 5 (a), the road surface drainage channel 50 is cut so that the cut surface X is inclined, and the road surface drainage channel 50 cut into a trapezoidal shape is connected so as to match the curvature. It can connect using the plate P1.

  Further, the road surface drainage channel 60 in FIG. 5B shows a case where a curved standard steel pipe 51 is used instead of cutting the road surface drainage channel 50 as described above. Even if the steel pipe 51 is curved, a water passage hole can be provided as in the case of a straight steel pipe. Further, the water guide plate 52 only needs to bend the two plates according to the curvature. Therefore, unlike the conventional road surface drainage channel 100 of Patent Document 3, it is not necessary to bend and assemble each member. Further, even if the two plates of the water guide plate 52 are not bent with high accuracy, they cannot be attached to the steel pipe 51, and thereby rainwater or the like cannot be guided into the steel pipe.

  FIG. 6 shows a process of manufacturing a road surface drainage channel 70 which is another example of the road surface drainage channel of the present application.

  FIG. 6A shows a steel pipe 61 which is a drainage channel portion of the road surface drainage channel 70 of the present invention. The steel pipe 61 is not processed separately except for using a standard product as it is and cutting it to a desired length.

  In FIG. 6 (b), a water passage hole 63 is provided on the side surface of the steel pipe 61, and a water passage hole 64 extending in the longitudinal direction is provided on the upper surface of the steel pipe 61. The water passage hole 63 and the water passage hole 64 may be formed by various methods. However, when the return to the inside of the steel pipe 61 occurs, the flow of the drainage in the steel pipe 61 is obstructed. Laser processing that does not occur is desirable.

  Moreover, what is necessary is just to change suitably the magnitude | size and the number of the water flow holes 63 provided in the side surface of the water flow hole 64 and the steel pipe 61 according to the drainage amount etc. of the place where the drainage path 70 for road surfaces is installed.

  6 (c), the upper plate having a water passage hole 63 as a water transfer auxiliary member, the surface is directed toward the water passage hole 63 (in the figure, toward the center line α of the water passage hole 63). A) An anti-slip steel plate 65 having a substantially U-shaped cross section that is slightly inclined is prepared. The non-slip steel plate 65 has a shape that matches the shape of the upper surface of the steel pipe 61. Further, the position of the water passage hole 63 is such that the water passage hole 63 and the water passage hole 64 overlap when the non-slip steel plate 65 is installed on the upper surface of the steel pipe 61. Therefore, when the non-slip steel plate 65 is installed on the upper surface of the steel pipe 61, the rainwater collected more efficiently by the surface of the non-slip steel plate 65 that is slightly inclined is passed from the water hole 63 to the water hole 64. Thus, the water can be reliably drained into the steel pipe 61.

  FIG. 6D shows a state in which the anti-slip steel plate 65 is installed on the upper surface of the steel pipe 61 and is welded to complete the road surface drainage channel 70. Thus, since the non-slip steel plate 65 having a substantially U-shaped cross section is welded and attached to the steel pipe 61, the road surface drainage channel 70 can be made robust.

  As described above, in the process of manufacturing the road drainage 70 of the present application, the standard steel pipe 61 is cut to a desired length, the water holes 63 and the water holes 64 are provided, and the water holes 63 are formed. It is only necessary to attach the provided anti-slip steel plate 65 to the upper surface of the steel pipe 61, and the manufacturing operation is very easy.

  In addition, depending on the specifications of the drainage channel for the road surface, after the non-slip steel plate 65 is attached to the upper surface of the steel pipe 61, the water passage hole 63 penetrating the non-slip steel plate 65 and the steel pipe 61 is formed by laser or the like from the upper surface of the anti-slip steel plate 65. Can be provided. Therefore, in the manufacturing process, it is necessary to separately provide the water passage hole 64 (see FIG. 6B) on the upper surface of the steel pipe 61 and the water passage hole 63 (see FIG. 6C) on the upper surface of the non-slip steel plate 65. Therefore, the operation is simplified and the manufacturing cost can be further reduced.

  FIG. 7 shows a use mode in which the road drainage channel 70 of the present application is installed in the road surface. The road surface drainage channel 70 is a side end of the water-permeable pavement R, and is embedded in the base crushed stone or basic cocrete U along the curb B. The surface of the water-permeable pavement R is slightly inclined toward the non-slip steel plate 65. And the upper surface of the anti-slip steel plate 65 is located on the same plane as the surface of the surface layer R, and the rainwater flowing on the surface of the surface layer R is directed toward the water passage hole 63 (in the drawing, the water passage hole 63 The surface of the non-slip steel plate 65 which is slightly inclined (toward the center line α) collects water more efficiently and is reliably guided to the inside of the steel pipe 61 through the water guide hole 63. Thus, the road surface drainage channel 70 has high water collection efficiency. In addition, rainwater that has penetrated into the interior of the water-permeable pavement R can be collected from a water flow hole 63 provided on the side surface of the steel pipe 61. Furthermore, although the upper surface of the anti-slip steel plate 65 is exposed on the road surface, the anti-slip effect is provided by the unevenness of the upper surface, so that the safety of pedestrians and the like can be ensured.

  Further, in another example of the road surface drainage channel of the present application, there is a method for manufacturing a road surface drainage channel embedded in the road surface, and a water passage hole extending in the longitudinal direction is provided on the upper surface of a standard steel pipe to be embedded. An upper plate having a water passage hole and having a surface inclined toward the water passage hole (preferably one having an anti-slip effect such as a non-slip steel plate) is welded to the upper surface of the steel pipe.

  Further, in another example of the road surface drainage channel of the present application, there is provided a method for manufacturing a road surface drainage channel embedded in the road surface, and the water flow to be provided on the surface of the standard steel pipe to be embedded. An upper plate having an inclined surface (preferably one having an anti-slip effect such as an anti-slip steel plate) is welded toward the hole, and a water passage hole is provided from the upper surface of the upper plate.

  Due to the above features, since a standard steel pipe is used, the manufacturing cost can be reduced, and the upper plate is attached to the upper surface of the steel pipe, so that the strength of the drainage channel for the road surface is improved. In addition, since the manufacturing method is easy, the manufacturing work can be reduced and the manufacturing cost can be reduced as a result. Furthermore, if a non-slip steel plate having an anti-slip effect is used for the upper plate, the safety of pedestrians and the like can be ensured.

  FIG. 8 shows a process of manufacturing a road surface drainage channel 110 which is another example of the road surface drainage channel of the present application.

  In FIG. 8A, a steel pipe 101 which is a drainage channel portion of the road surface drainage channel 110 is shown. The steel pipe 101 is not processed separately except that a standard product is used as it is and cut into a desired length. Next, in FIG. 8B, the surface is slightly W-shaped toward the water passage hole 104 to be provided on the surface (in the drawing, toward the center line α of the water passage hole 104). An inclined steel plate 105 having a substantially U-shaped cross section is prepared. Thus, since the surface of the steel plate 105 is slightly inclined, rain water from the road surface can be collected and drained more efficiently. The steel plate 105 has a shape that matches the shape of the upper surface of the steel pipe 101.

  FIG. 8C shows a state where the steel plate 105 is installed on the upper surface of the steel pipe 101 and welded. Thus, since the steel plate 105 having a substantially U-shaped cross section is welded and attached to the steel pipe 101, the road drainage channel is robust. Further, the steel plate 105 is riveted between the upper surface of the steel pipe 101 and the steel plate 105 without performing welding (in the figure, the rivets F are driven into the four corners of the steel plate 105, but may be appropriately driven at arbitrary positions. Can also be made removable. FIG. 8E is an enlarged cross-sectional view of the road drainage channel 110. The steel plate 105 is detachably attached to the upper surface of the steel pipe 101 by the driven rivets F. FIG. In addition, it can attach not with the rivet F but with a volt | bolt and a nut so that attachment or detachment is possible, and other attachment members can also be used suitably.

  Next, as shown in FIG. 8 (d), a water passage hole 104 that penetrates the upper surface of the steel plate 105 and the steel pipe 101 and communicates with the inside of the steel pipe 101 is processed from the upper surface of the steel plate 105 by laser or the like (referred to as co-processing). The road surface drainage channel 110 is thus completed. According to the manufacturing process shown in FIG. 8, as in the manufacturing process shown in FIG. 6, the water passage hole 64 on the upper surface of the steel pipe 61 and the water passage hole 63 on the upper surface of the non-slip steel plate 65 (see FIG. 6C). Need not be provided separately, the manufacturing process is simplified, and the manufacturing cost can be further reduced. The shape of the steel plate 105 may be a simple plate shape or any other shape. In addition, the material of the steel plate 105 and the surface treatment thereof can be appropriately changed according to the application. For example, if the surface finish is applied with a non-slip treatment, an anti-slip effect can be obtained, and color processing is performed. If it is painted, the aesthetics can be improved.

  FIG. 9A shows a steel pipe 111 which is a drainage channel portion of the road surface drainage channel 120. This steel pipe 111 is not processed separately except that a standard product is used as it is and cut into a desired length. Next, in FIG. 9B, a water passage hole 113 is formed in the steel pipe 111, and a water passage hole 114 extending in the longitudinal direction is provided at the center of the upper surface of the steel pipe 111 by laser processing or the like.

  In FIG. 9C, a water passage hole 113 is provided as a water transfer auxiliary member, and the surface is inclined toward the water passage hole 113 (in the drawing, toward the center line α of the water passage hole 113). An anti-slip steel plate 115 is prepared. The slope of the surface of the anti-slip steel plate 115 is larger than the slope of the surface of the anti-slip steel plate 65 of FIG. 6, and the cross-section of the anti-slip steel plate 115 is substantially M-shaped. 113 is provided. When this anti-slip steel plate 115 is installed on the upper surface of the steel pipe 111, the water passage hole 113 and the water passage hole 114 overlap each other. Further, if the round bar 115a is arbitrarily attached to the recess on the back side of the anti-slip steel plate 115, the anti-slip steel plate 115 can be more stably installed on the upper surface of the steel pipe 111. In addition, if the non-slip steel plate 115 has a color on the surface (color steel plate), the aesthetics can be improved.

  FIG. 9 (d) shows a state where the non-slip steel plate 115 is installed on the upper surface of the steel pipe 111 and is welded to complete the road surface drainage channel 120. Thus, by using the non-slip steel plate 115 whose surface is inclined toward the water passage hole 113, rainwater from the road surface can be collected more efficiently and reliably guided to the steel pipe 111.

  Next, in FIG. 10, the various modifications of a pair of water conveyance assistance tools provided in the steel pipe upper surface are shown. First, in the road drainage channel 130 of FIG. 10A, a pair of plate members 122 having a substantially L-shaped cross section are attached to the upper surface of the steel pipe 121. Although not shown, the plate material 122 (1) and the plate material 122 (2) are attached so as to sandwich a water passage hole 124 provided on the upper surface of the steel pipe 121. Therefore, rainwater from the road surface is guided between the plate material 122 (1) and the plate material 122 (2) to the water passage hole 124 and drained into the steel pipe 121. Further, since the cross section of the plate material 122 is substantially L-shaped, it is easy to arrange the plate material 122 on the upper surface of the steel pipe 121.

  Next, in the road surface drainage channel 140 of FIG. 10B, a pair of round members 132 are attached to the upper surface of the steel pipe 121. Even in this case, as with the plate member 122, rainwater from the road surface passes between the round members 132 (1) and the round members 132 (2), is guided to the water passage holes 134, and is drained into the steel pipe 131.

Next, the road surface drainage channel 150 in FIG. 10C is attached with a pair of plate members 142 whose surfaces are inclined so as to sandwich a water passage hole 144 provided on the upper surface of the steel pipe 141. The plate member 142 can guide the drainage from the road surface to the water passage hole 144 through the plate member 142 (1) and the plate member 142 (2), and since the surface is inclined, rainwater from the road surface, etc. It is easy to collect water.
Thus, although the various modifications of the water conveyance assistance tool were shown, the shape of the water conveyance assistance device is an area where rainwater at the upper end of the water conveyance assistance device can flow in so that more rainwater can flow in than the water passage hole. However, what is necessary is just to become more than the opening area of a water flow hole.

  Next, the road surface drainage channel 160 in FIG. 10D is provided with a water passage hole 154 on the upper surface of the steel pipe 151 (not shown), and a plate material 152 (1) and a plate material 152 ( 2) is attached. A material T having water permeability is spread between the plate material 152 (1) and the plate material 152 (2). Since this material T has water permeability, road surface rainwater and the like can be collected from the material T and drained into the steel pipe 151 through the water passage hole 154. Furthermore, if natural stones or ceramics having water permeability are used as the material T, the aesthetics of the road surface in which the road surface drainage channel 160 is embedded can be improved.

  In the drainage channel for road surface in FIG. 11A, a water passage hole 164 a and a water guide plate 162 a are provided on the upper surface of the steel pipe 161 so as to sandwich the water passage hole 164 a. Similarly, a water guide plate 162b is provided so as to sandwich the water hole 164b (not shown) and the water hole 164b.

  Then, as shown in FIG. 11B, the boundary block G is installed and integrated between the water guide plate 162a and the water guide plate 162b provided at both ends of the upper surface of the steel pipe 161. In the road surface drainage channel 170 in which the boundary block G is integrated in this way, the road surface is separated by the boundary block G, and rainwater and the like can be drained from the separated road surfaces through the water guide plate 162a and the water guide plate 162b.

  In the drainage channel for road surface 180 in FIG. 12A, a grating 175 is fitted between two parallel plates 172 (1) and 172 (2) constituting the water guide plate 172. Although not shown, the parallel plates 172 (1) and 172 (2) are provided so as to sandwich a water passage hole 174 provided on the upper surface of the steel pipe 171. Therefore, the water guide plate 172 can fix the grating 175 and can guide rainwater collected from above the grating 175 into the steel pipe 171 through the water hole 174. In addition, if the lattice portion of the grating 175 is laid with a water-permeable material T, the aesthetics are improved.

  Furthermore, since the water guide plate 172 is installed by welding on the upper surface of the steel pipe 171, the width between the parallel plates 172 (1) and 172 (2) can be arbitrarily determined. Therefore, when it is desired to additionally attach the grating 175, it is only necessary to install the parallel plates 172 (1) and 172 (2) in accordance with the width of the grating 175 and to fit the grating 175. As described above, the road surface drainage channel 180 is easy to be added and processed even when it is desired to additionally install the equipment such as the grating 175, and can be dealt with immediately.

  Moreover, in the drainage channel 190 for road surfaces of FIG.12 (b), only the water flow hole 184 (not shown) and the grating 185 are provided. Even if the parallel plates 172 (1) and 172 (2) are not provided as shown in FIG. 12 (a), the side plates 185 (1) and 185 (2) which are part of the grating main body serve as a water guide plate. As a result, rainwater can be collected. The grating 185 may be fixed to the upper surface of the steel pipe 181 by welding.

  The road surface drainage channel of the present invention is not limited to the above-described examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments. Examples and combinations are also included in the scope of rights.

  The road surface drainage channel of the present invention can be used in industrial fields where it is required to drain rainwater on road surfaces such as sidewalks, roads, and parking lots.
