(Action / effect)
According to the gutter underdrain pipe connection joint 5x and 5y and the connection structure thereof according to the present embodiment, the following effects can be exhibited.

As shown in FIGS. 2 (a), 2 (b), and 2 (c), unlike the conventional example in which the gutter 2 and the underdrain pipe 1 are connected by using the catchment basin 4 shown in FIG. Since the gutter 2 and the underdrain pipe 1 are connected by the joint body 7 without using the catchment basin 4, there is no concern that the grating 3 of the catchment basin 4 will be stolen, and water, dust, etc. will be collected in the catchment basin 4. It does not accumulate and cause odor. Maintenance to remove dust, fallen leaves, pebbles, etc. accumulated in the catchment basin 4 becomes unnecessary, and maintenance cost can be reduced.

As shown in FIG. 2 (c), the joint body 7 is formed in a plate shape along the vertical direction and has openings 8 and 9 for connection formed on both side surfaces, so that the joint body 7 is formed from a square cylinder having a side of about 80 cm. It is more compact than the catchment basin 4 shown in FIG. 1, the amount of excavated sediment when burying in the road is reduced, and the load of installation work on the road can be reduced. Since the size of the concrete joint body 7 is more compact than that of the catchment basin 4, the amount of concrete used is smaller than that of the catchment basin 4, and it can be manufactured at a lower cost than the catchment basin 4. In addition, since the metal grating 3 is not required, it is cheaper than the water collecting basin 4.

As shown in FIG. 2 (c), the convex portion 13 of the end surface of the underdrain pipe 1 is engaged with the concave portion 19 formed on one side surface 7a of the side groove underdrain pipe connecting joint 5x, and the concave portion 16 of the end surface of the underdrain pipe 1 is engaged. Is engaged with the convex portion 18 formed on one side surface 7a of the side groove underdrain pipe connecting joint 5y, so that the connection rigidity is increased, and the automobile passes through the road above the underdrain pipe 1 and loads the underdrain pipe 1. It is possible to suppress the deviation of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 8 caused by the addition of fluctuations. That is, instead of abutting the end surface of the underdrain pipe 1 against the side surface 7a of the joint 5x and 5y in a plane, the convex portion 13 and the concave portion 16 for connecting the underdrain pipes 1 are used to make the convex portion of the underdrain pipe 1 convex. By engaging the portions 13 and the concave portions 16 with the concave portions 19 and the convex portions 18 of the joints 5x and 5y, it is possible to suppress the displacement of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 8 due to vibration or the like.

When the underdrain pipe 1 shown in FIG. 3A is connected to the side groove underdrain pipe connecting joint 5x shown in FIG. 5A, a screw rod (not shown) provided in the accommodating portion 17 of the underdrain pipe 1 is attached to the joint 5x.

A screw rod (not shown) provided in the accommodating portion 17 is screwed into the female screw member 20 embedded in one side surface 7a of the joint 5y. In this way, since the underdrain pipe 1 and the joints 5x and 5y are connected by using the screw rod for connecting the underdrain pipe 1 to each other, the connection rigidity is further increased, and the road above the underdrain pipe 1 is driven by an automobile. The deviation of the underdrain pipe 1 with respect to the underdrain pipe connecting opening 19 caused by the load fluctuation applied to the underdrain pipe 1 can be further suppressed.

As shown in FIG. 2 (c), a mounting plate 21 on which the lower surface of the gutter 2 is placed is provided on the other side surface 7b of the gutter underdrain pipe connecting joint 5x, and the other side surface 7b of the gutter underdrain pipe connecting joint 5y is provided. Since the mounting plate 21 on which the lower surface of the gutter 2 is mounted is provided, it is possible to prevent the gutter 2 from shifting up and down with respect to the gutter connecting opening 9 due to the ground subsidence over time. Further, as shown in FIGS. 2 (b), 4 (b), and 5 (b), the gutter 2 is placed on the other side surface 7b of the joint 5x and 5y when the gutter 2 is mounted on the mounting plate 21 from above. Since a pair of vertical walls 22 are provided to guide the left and right side portions of the gutter, it is possible to prevent the gutter 2 from shifting to the left and right with respect to the gutter connecting opening 9 over time.

As shown in FIGS. 4 (b), 5 (b), and 9, the pair of vertical walls 22 are formed in a slope shape so as to widen the distance from the lower part to the upper part, so that the gutter 2 is upward. When the gutter is mounted on the mounting plate 21, the centering property is improved, the gutter 2 can be easily aligned with the gutter connecting opening 9, and the workability of construction is improved. Further, since the pair of vertical walls 22 are formed in a slope shape so as to widen the space from the lower part to the upper part, it is easy to remove the ready-mixed concrete from the formwork after pouring the ready-mixed concrete into the formwork at the time of manufacturing.

As shown in FIGS. 4 (b), 5 (b), and 6, the pair of vertical walls 22 are formed in a tapered shape so as to increase the distance from the other side surface 7b of the joint body 7. Therefore, when the gutter 2 is brought closer to the other side surface 7b of the joint body 7, the centering property is enhanced, the gutter 2 can be easily aligned with the gutter connecting opening 9, and the workability of construction is improved. Further, since the pair of vertical walls 22 are formed in a tapered shape so that the distance becomes wider as the distance from the other side surface 7b of the joint body 7 increases, ready-mixed concrete is poured into the formwork at the time of manufacturing and then placed. Easy to remove from the formwork.

As shown in FIGS. 2 (b) and 2 (c), by inserting the dust collecting wire mesh 24 into the slit 25 formed between the joint body 7 and the side groove 2 from above, the side groove 2 is inserted together with rainwater. The flowing fallen leaves, dust, pebbles, etc. can be collected by the dust collecting wire mesh 24, and the situation where the fallen leaves, dust, pebbles, etc. flow into the gutter can be avoided.

As shown in FIG. 9, the wire mesh recess 23 formed on one side surface 7a of the plate-shaped joint body 7 and the thick portion of the end surface of the side groove 2 connected to the side surface 7a are made to cooperate with each other. Since the slit 25 is formed, for example, a slit for the dust collecting wire mesh 24 is formed in the center of the top surface 6 of the joint body 7 shown in FIG. 5B in the plate thickness direction by placing concrete in the vertical direction. The core, which is required in some cases, is no longer required, and the joint body 7 can be manufactured at low cost.

The fallen leaves, dust, pebbles, etc. collected in the dust collecting wire mesh 24 can be removed from above by removing the lid plate 2a of the gutter 2 adjacent to the gutter underdrain pipe connecting joint 5x and 5y. Further, by inserting a finger into the finger insertion recess 26 and pulling up the dust collecting wire mesh 24, the inside of the underdrain pipe 1 can be inspected from the gutter 2, and the fallen leaves, dust, pebbles and the like that have invaded the inside can be scraped out.
