Abstract

(57) [Summary] [Objective] To provide a drainage structure in which the drainage capacity is greatly increased in a box type or a gutter with a lid. A grating groove 4 is provided in the longitudinal direction of the top plate portion 1a of the box-shaped side groove 1 to the lid portion 2a of the side groove 2 with a lid.
Draining vertical holes 5 communicating with a drainage channel 3 having a cross-sectional width equal to the width of the grating groove 4 are formed at the bottom of the grating groove 4 at predetermined intervals, and the grating groove 4 is grating. It is a drainage structure constructed by dropping down 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage structure in a box-type gutter and a gutter with a lid.

[0002]

[Prior art]

 In the drainage structure of box-type gutters that has been generally implemented so far, a grating groove is formed in the longitudinal direction of the top plate, and the bottom longitudinal direction of the grating groove and the drainage channel are the same as those of the above-mentioned grating. They are connected by communication holes that are narrower than the cross-sectional width of the trenching groove, and the running water on the road surface that has flowed in through the draining holes of the grating groove is guided to the drainage channel through the narrow communication hole. In addition, a part of the structure in which a drainage hole is provided in the top plate of the box-type gutter itself to perform a grating function is widely used. However, any of the above drainage structures cannot be judged when there is a large amount of water such as during heavy rain and thunderstorms, and they overflow around the road to cause traffic obstacles. Also, in the former case, the communication hole and in the latter case, the drain hole is apt to be clogged with dust and the like, which deteriorates drainage efficiency and requires maintenance work. Further, in the former case, since the communication hole is configured to divide the top plate portion of the box carbur, there is also a problem in terms of strength, and the width of the communication hole is naturally limited.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned conventional circumstances, and is intended to obtain a drainage structure in which the drainage capacity is remarkably increased, although it is basically a grating system.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a grating groove 4 in the longitudinal direction of the top plate portion 1a of the box-shaped side groove 1 to the lid portion 2a of the lid-side groove 2, and the bottom portion of the grating groove 4 is provided. Further, vertical drainage holes 5 communicating with the drainage channel 3 having a cross-sectional width equal to the width of the grating groove 4 are provided at predetermined intervals. Then, the grating 6 having the drainage holes 7 arranged therein is dropped into the grating groove 4 to form a drainage structure.

[0005]

【Example】

 1 and 2 show an embodiment in the case of a box-shaped gutter, and FIG. 3 shows an embodiment in the case of an L-shaped gutter 2 with a lid.

[0006]

[Action]

 A large amount of running water, which is generated during heavy rain, flows into the grating groove 4 through the water draining hole 7 of the grating 6, and the water draining vertical holes 5 are provided at the bottom of the groove 4 at predetermined intervals. However, in the present invention, the cross-sectional width of the drainage vertical hole 5 is comparable to the width of the grating groove 4 (in other words, the side wall surface of the grating groove 4). Since the downward extension is the side wall surface of the water draining vertical hole 5, the running water flowing in from the water draining hole 7 of the grating 6 as shown in FIG. It diverts to the left and right) or unilaterally to one side that is transparent, and collectively and efficiently drops into the drainage channel 3. At this time, there is no need to worry about dust or the like getting caught in the water draining vertical hole 5 and causing clogging. As a result, it is possible to avoid the situation where running water overflows around the road and causes traffic problems.

[0007]

[Effect of the device]

 From the above, the present invention can provide a drainage structure in which the drainage capacity is greatly increased in the box type or the gutter with the lid. In addition, since the draining vertical holes 5 communicating with the drainage channel 3 having a sectional width equal to the width of the grating groove 4 are formed at the bottom of the grating groove 4 at predetermined intervals, the draining vertical hole 5 is formed. The non-filled portion functions as a supporting beam, and the strength as a box carve or the lid part of the gutter with a lid is sufficiently obtained.
