As a countermeasure against such a situation, there is an urgent need to improve the drainage function of waterways such as rivers, various roads, and gutters in each area. It may be necessary and the working time is long.

In order to solve the above problem, in the registered utility model No. 3171738 (Patent Document 1), the road surface and the inclination of the waterway of the planned side groove laying site are determined before the construction, and the side groove main body to be laid and its base are used. We are proposing a technical construction structure that will produce an invert unit based on the planned inclination and lay it on the day of work to reduce construction time and cost.

However, in the technical proposal of Patent Document 1, since the gutters are produced in advance for each inclination angle, there is a problem that fine adjustment is required when connecting the gutters at the site, and the installation work is rather complicated. In addition, since the side surface of the gutter is completely covered with concrete, there is also a problem that it cannot handle drainage from a road provided with permeable pavement.

The applicant pays attention to the above-mentioned functional problems in the conventional gutters, and cannot provide a gutter that can easily cope with the inclination when the gutter is installed and can also cope with permeable pavement. Based on the idea of a gutter, we have developed a gutter that can easily cope with inclination at the site when installing a gutter and that can accept drainage from permeable pavement, and the "upper and lower split type gutter" according to the present invention. It leads to the proposal of.

FIG. 6 is an explanatory view showing an embodiment of the vertically split type gutter 1 according to the present invention, and shows a connected state. 7A and 7B are explanatory views showing an embodiment of the vertically split type gutter 1 according to the present invention, in which FIG. 7A is a transmission side view showing a construction state of a free gradient forming operation, and FIG. 7B is an exploded perspective showing the same state. It is a figure.

The upper and lower split type gutter 1 according to the present invention is entirely molded into a substantially rectangular parallelepiped shape by concrete, and is divided into upper and lower parts by a main body 10 and a lid 20, and is vertically divided suitable for a road provided with permeable pavement. It is a gutter of the mold. The overall length, width, and height are not particularly limited, but for example, the main body is molded into a length of 1000 to 2000 mm, a width of 300 to 1000 mm, and a height of 280 to 2200, and each upper and lower split type gutter 1 is formed. A plurality of gutters are connected in a column and function as a gutter having a drainage function for rainwater and the like.

The main body 10 is formed with a U-shaped drainage channel 12 having an open upper portion so as to penetrate both end surfaces 10a and 10b in the longitudinal direction. The specific shape of the drainage channel 12 is not particularly limited, and may be an R shape, a substantially V shape, a polygonal shape, or the like, in addition to the rectangular shape as shown in the figure. The drainage channel 12 functions as a drainage path for inflowing rainwater or the like by pouring concrete C into the drainage channel 12 to form a free gradient.

The lid 20 closes the upper part of the main body 10, and an inverted U-shaped drainage channel 22 having an open lower portion is formed so as to penetrate both end surfaces 20a and 20b in the longitudinal direction. The specific shape of the drainage channel 20 is not particularly limited, and may be an R shape, a rectangular shape, or the like, in addition to the polygonal shape as shown in the figure. The drainage channel 22 functions as an inflow route for rainwater or the like from the top surface drainage hole 24 and the side surface drainage hole 26, which will be described later, and as a drainage route for rainwater or the like that has flowed in integrally with the drainage channel 12 of the main body 10. ..

The lid 20 is formed by a rigid frame structure. In the case of a general flat-type gutter lid, since it is weak in strength, there is a risk that cracks will occur when an external pressure is applied from above. On the other hand, the lid 20 according to the present invention has an inverted U shape, and by adopting a molding mode having a rigid frame structure, the balance of proof stress and strength against external pressure is improved, and the lid 20 is covered even when external pressure is applied from above. Cracks are less likely to occur on the top surface of the 20th surface, functionality and durability are improved, and the safety of pedestrians and bicycles actually passing above is ensured.

The top surface of the lid 20 is provided with a plurality of top surface drain holes 24 that vertically penetrate to the drainage channel 22. Regarding the number of top drainage holes 24 in one lid 20, if only one is provided, the inflow routes of rainwater and the like to the drainage channel 22 will be concentrated at one point, resulting in deterioration of water entry efficiency. It is assumed that there is no alternative inflow route due to clogging with dust, and if too many top drainage holes 24 are provided, the strength of the top surface will be insufficient and it is assumed that a reinforcing structure will be essential. A mode in which the top surface drainage hole 24 is provided is preferable. The shape of the top surface drainage hole 24 is not particularly limited, but if it is too small, there is a difficulty in the water entry capacity, and if it is too large, the strength of the top surface may be insufficient. A substantially rectangular shape having a width of about 150 mm and a width of about 20 mm is preferable. The position where the top drainage hole 24 is provided is not particularly limited as long as it can penetrate the drainage channel 22 in the vertical direction, but for example, as shown in the figure, at a substantially central position in the width direction, a predetermined interval (for example, an even interval). ) Is vacant and prepared in tandem.

As shown in the figure, the top surface layer of the lid 20 is provided with a downward slope toward the top drainage hole 24 in the width direction. By adopting such an embodiment, rainwater or the like flowing on the surface layer of the top surface is surely guided to the top surface drainage hole 24 without flowing out to the outside.
Further, the top surface layer of the lid 20 is subjected to anti-slip processing 28. By applying such anti-slip processing 28, it is possible to prevent the risk of falling due to slipping when a pedestrian, a bicycle or the like passes through the relevant portion, and contribute to the improvement of safety. The specific means of the anti-slip processing 28 is not particularly limited, and for example, as shown in the figure, in addition to an embodiment in which a concave-convex shape is applied, an embodiment in which a surface layer is treated with fine aggregate, an embodiment in which an anti-slip paint is applied, and the like. , Various means can be adopted.

A plurality of side drainage holes 26 that obliquely penetrate to the drainage channel 22 are provided at a portion above one side surface of the lid body 20. Regarding the number of side drainage holes 26 in one lid 20, if only one is provided as in the case of the top drainage hole 24, the inflow route of rainwater or the like to the drainage channel 22 will be concentrated at one point. Therefore, it is assumed that the water entry efficiency will deteriorate and that there will be no alternative inflow route due to clogging with dust, and if too many side drainage holes 26 are provided, the strength of the upper part of the side surface will be insufficient, and a reinforcing structure will be required. Therefore, it is preferable to provide the side drain holes 26 at about 2 to 4 locations. The shape of the side drainage hole 26 is not particularly limited, but if it is too small, there is a difficulty in the water entry capacity, and if it is too large, the strength of the upper part of the side surface may be insufficient. It is preferable that the shape is substantially rectangular. The position where the side drainage hole 26 is provided is not particularly limited as long as it is an upper portion on the side surface of the lid 20 and can penetrate from the side surface to the upper position of the drainage channel 22 in an inclined manner. In terms of the function of allowing rainwater or the like that has entered the permeable pavement to flow in, it is preferable that the pavement is provided at a position about 10 to 16 mm below the top surface. Further, the plurality of side drain holes 26 provided in one lid 20 are provided so that all the height positions thereof are substantially the same. Then, as shown in the figure, the side drain holes 26 are provided in tandem at predetermined intervals (for example, even intervals).

A slit groove 27 is formed in the upper part of the side surface of the lid 20. The slit groove 27 is formed by penetrating in the longitudinal direction while passing through the side drain hole 26 provided on the side surface of the lid 20, in other words, on the side surface where the side drain hole 26 is not formed. Will not form the slit groove 27 either. The slit groove 27 is formed substantially horizontally by passing through all the side drain holes 26 existing at the same height position. By forming the slit groove 27, it is possible to reliably guide the rainwater or the like flowing in from the permeable pavement to the side drainage hole 26, that is, when the rainwater or the like that has entered the permeable pavement flows in. After passing through the slit groove 27 once, it will flow into the drainage channel 22 from the side drainage hole 26 on the near or downstream side. The slit width of the slit groove 27 is not particularly limited, but is, for example, about 5 to 10 mm.

Lateral engaging grooves 14 are formed at both ends of both side surfaces of the main body 10. The lateral engaging groove 14 is a portion for engaging a joint member for connecting the main bodies 10, and the lateral engaging grooves 14 provided so as to face each other in the vicinity of the connecting surface when the main bodies 10 are connected to each other. In addition, joint members are erected to bind each other. By providing such a lateral engaging groove 14, it becomes easy to connect the main bodies 10 to each other, which contributes to reducing the burden of installation work, and prevents water leakage due to poor connection of the connecting surfaces to ensure a reliable and smooth flow path. It contributes to the formation, and can also be expected to have the effect of suppressing the displacement of the connecting points in the event of a natural disaster such as an earthquake. The means for engaging the joint member in the lateral engaging groove 14 is not particularly limited, and screwing with bolts and nuts can be considered.

Further, in addition to the horizontal engaging groove 14, a vertical engaging groove 16 is also formed on both upper ends of both side surfaces of the main body 10. At the same time, vertical engaging grooves 29 are also formed in the lower ends of both side surfaces of the lid 20. The vertical engaging grooves 16 and 29 are portions for engaging joint members for connecting the main body 10 and the lid 20, respectively, in the vicinity of the connecting surface when the main body 10 and the lid 20 are connected to each other. A joint member is erected between the lateral engaging grooves 16 and 29 provided so as to face each other to fasten each other. In this way, by providing the vertical engaging grooves 16 and 29, the connection work between the main body 10 and the lid 20 becomes easy, which contributes to the reduction of the burden of the installation work, and the connecting surfaces are brought into close contact with each other. It can be expected to prevent water leakage and foreign matter from entering due to poor connection, contribute to the formation of a reliable and smooth flow path, and further suppress the displacement of the connection points in the event of a natural disaster such as an earthquake. The means for engaging the joint members in the vertical engaging grooves 16 and 29 is not particularly limited, and screwing with bolts and nuts can be considered.

Regarding the installation mode of the vertically divided type gutter 1 according to the present invention configured as described above, it is sufficient to bury the vertically divided type gutter 1 in the excavated installation place according to the installation mode in the conventional side groove equipment. That is, after excavating the installation location of the side groove equipment and paving stones at the excavated location with crushed stone, the main bodies 10 are arranged in the excavated location by the required number of units, and the main bodies 10 are joined to each other in that state. The lid 20 is placed together with each of the main bodies 10, the main body 10 and the lid 20 are joined by a joint member, and finally the circumference of the upper and lower split type side grooves 1 is backfilled.
An arbitrary gradient is formed by pouring concrete C into the drainage channel 12 of the main body 10 as needed before placing the lid body 20.
Further, when the lid 20 is placed, the side surface provided with the side drain hole 26 is placed facing the road surface side provided with the permeable pavement. Then, when the circumference of the upper and lower split type gutter 1 is backfilled, the road surface is permeable pavement so that the area below the side drainage hole is the impermeable layer and the area above the side drainage hole is the water permeable layer. ..

As described above, according to the upper and lower split type gutter 1 according to the present invention, the drainage flowing on the ground is introduced into the drainage channel 22 through the top surface drainage hole 24, and the drainage that has infiltrated into the paved path by the permeable pavement. Is introduced into the drainage channel 22 through the side drainage hole 26. Since the slit groove 27 passing through the side drainage hole 26 is formed on the side surface of the lid 20, the drainage dispersion treatment can be performed through the slit groove 27 when a large amount of drainage is generated or when the side drainage hole 26 is clogged. It will be possible.
Further, in the installation work of the vertically divided type gutter 1, the height variation of the lid 20 can be made constant by changing the height of the main body 10 according to the gradient of the installation location and the excavation depth. It will contribute to the efficiency of work.

The upper and lower split type gutters according to the present invention have excellent dispersion treatment capacity when a large amount of wastewater is generated, and also have excellent effects on workability, transportability, and safety. The present invention can be used in situations. Therefore, it is considered that the availability of the "upper and lower split type gutters" according to the present invention is great.
