JP5526210B2 - Flowing structure of gutter block - Google Patents

Description

The present invention relates to a structure of a passage for running water in a concrete block forming a side groove of a road.

A gutter on a road is formed by a series of gutter blocks, but it is a headache that dust flows along with running water and blocks the entrance of the gutter block. In particular, when a plastic bottle floats and closes the entrance, the problem is serious because the area covered is large.

JP2009-7889A

As in Patent Document 1, it has been proposed that a block in which a lower water channel and an upper water channel have a two-story structure have a structure that guides rainwater accumulated in the upper water channel from a rainwater fall gap to the lower water channel. However, since this rainwater fall gap is narrow, there is a risk of flooding the road surface during heavy rain.
If this rainwater fall gap is increased, the rainwater passage will be enlarged, so it is easy to think that flooding of the road surface can be prevented. Can not prevent flooding of the road surface.
The technical problem of the present invention pays attention to such a problem, and in the side groove block, the PET bottle cannot pass through the inlet of the flow path where the running water from the road flows down, and the PET bottle can pass through the other flow paths. The purpose is to prevent flood damage by preventing the road surface from being flooded.

Claim 1 is a concrete block in which a curb wall that also serves as a curb of a road is molded integrally with a gutter side through at least a side wall on the curb wall side .
The entrance of the flow path where the running water from the road flows down opens sideways except for both ends of the curb wall, and has a flow path for communicating with the gutter on the lower side of the curb wall ,
A horizontally divided two-part material is provided at an entrance wide enough to allow a PET bottle to pass through, and both ends thereof are inserted into grooves provided in advance at the left and right ends of the entrance and filled with adhesive means, so that the PET bottle is placed in the entrance. And the flow path other than the inlet is wide enough to allow the PET bottle to pass therethrough.

Claim 2 is a concrete block in which a curb wall that also serves as a curb of the road is molded integrally with the side groove side through at least a side wall on the curb wall side.
The entrance of the flow path where the running water from the road flows down opens sideways except for both ends of the curb wall, and has a flow path for communicating with the gutter on the lower side of the curb wall,
The flow path structure of the side groove block is characterized in that protrusions are provided intermittently at an entrance having a width that allows the PET bottle to pass therethrough so that the PET bottle cannot pass therethrough .

Claim 3, wherein it projections a pin-like member, in the flow channel structure of the gutter block according to claim 2 you wherein there Nde write planted inlet of the upper and / or pin-like body bottom is there.

According to a fourth aspect of the present invention, at least one opening narrower than the diameter of the plastic bottle is provided on the ceiling surface of the side groove block, and the flow rate of running water is increased by forming a flow-in port parallel to the inlet. The channel structure of the side groove block according to claim 1, claim 2, or claim 3.

As shown in FIG. 1, in the concrete block in which the curb wall that also serves as the curb of the road is integrally formed with the side groove through the side wall on the curb wall side as shown in FIG. Opens laterally from the curb wall and communicates with the side groove side through a flow path below the curb wall. In addition, the entrance is provided with a horizontally divided material at the entrance that allows the PET bottle to pass through, and both ends thereof are inserted into grooves provided in advance on the left and right ends of the entrance, and are filled with adhesive means. The structure is such that the PET bottle cannot pass through the inlet. Therefore, the PET bottle does not flow and flow downstream. On the other hand, the other flow paths are wide enough to allow the PET bottles to pass through them, so that a large amount of water can pass through. Moreover, even if a PET bottle flows to the entrance, the entrance is closed with the PET bottle, and the flow does not deteriorate.

As in claim 2, when the entrance is partially narrowed so that the PET bottle cannot pass and the entrance is partially narrowed so that the PET bottle cannot pass, the entrance is narrowed. Is partial and does not reduce the amount of running water, effectively preventing flooding of the road surface.

According to a third aspect of the present invention, when the projection is a pin-shaped body and the pin-shaped body is implanted on the upper side and / or the lower side of the inlet to prevent the plastic bottle from entering, the inlet is formed by the plastic bottle. It is rarely blocked and can earn a flow rate.

As in claim 4, by providing one or more openings narrower than the diameter of the PET bottles on the ceiling surface of the side groove block to form a flow-in port parallel to the inlet, Can be effectively prevented.

It is a figure which shows 1st embodiment of this invention, (1) is a perspective view, (2) is sectional drawing. It is a perspective view which shows 2nd embodiment for narrowing an inlet_port | entrance. It is a perspective view which shows 3rd embodiment for narrowing an inlet_port | entrance. It is a perspective view of the Example which reduced the concrete material and made it thin. It is a perspective view which shows the separated type Example divided into 2 parts up and down.

Next, an embodiment of how the flowing water structure of the gutter block according to the present invention is practically described will be described. FIG. 1 is a view showing a first embodiment of the present invention, where (1) is a perspective view and (2) is a cross-sectional view, and the side groove G is formed by connecting the side groove blocks shown in FIG. The concrete block is composed of a bottom wall 1 that forms the bottom, a top wall 2 that forms the ceiling, a curb wall 3 that also serves as a curb, a side wall 4 on the curb wall 3 side, and a side wall 5 on the road side. G is formed.
On the curb wall 3 side, the water on the road surface flows into the entrance i formed sideways while facing the road surface, and flows into the side groove G through the channel R in a standing state. The cross-sectional area D of the flow path R is preferably large so that a larger amount of water can flow into the side groove G. However, there is a possibility that a plastic bottle or the like flows and flows downstream or gets caught in a place where it cannot be visually observed.

Therefore, in the present invention, the inlet i is narrowed. That is, the dimension d is smaller than the diameter of the plastic bottle so that the plastic bottle cannot flow in. In order to prevent the small- capacity PET bottle having a small diameter from entering, the dimension d is made smaller than the diameter.
When it is desired to increase the flow rate, (1) an opening is provided in the top wall 2 as shown by a chain line 6 in the figure, and a metal grating 7 as shown in (2) is provided in the opening 6. Good. The opening 6 can be single as long as the plastic bottle cannot pass therethrough.

FIG. 2 is a perspective view showing a second embodiment for narrowing the inlet i, and protrusions 7 and 8 may be provided at predetermined intervals on the upper and lower edges of the inlet i. The distance between the upper and lower protrusions 7 and 8 is d. The region where the protrusions 7 and 8 do not exist is larger than d, but the interval between the protrusions 7 and 8 may be larger than the height (length) of the PET bottle.
Note that the upper and lower protrusions 7 and 8 do not face each other but can be formed alternately. In this case, the distance d between the protrusions 7 and 8 and the edge without the protrusion is made smaller than the outer diameter of the PET bottle.

The protrusions 7 and 8 have a shape that is long in the left-right direction. In this case, since it may break easily in concrete, it is better to implant a pin-like body immediately after the block is removed from the mold and before curing. In order to prevent the pin-shaped body from being easily detached, it is preferable that the pin-shaped body is formed in a male thread shape or the surface is roughened so that it can be easily integrated with the block.
When a pin-like body is used in place of the protrusions 7 and 8, it may be provided on one of the upper edge or the lower edge of the inlet i and is not necessarily provided on both sides. In the case of implanting a thin pin-like body, even if the PET bottle is blocked at the entrance i, the smooth flow of water is rarely blocked.

FIG. 3 is a perspective view showing a third embodiment for narrowing the inlet i. Grooves are formed in advance on the left and right sides of the inlet i, and both ends of the horizontal pipe 9 are inserted into the groove. Then, fill with adhesive means such as mortar. As a result, the horizontal pipe 9 does not easily come off.
In addition, it may replace with mortar and may fix the pipe 9 to a block with an adhesive material.

In the cross-sectional shape as shown in FIG. 1 (2), the thickness of the lower side of the back wall 4 is large and the concrete material is wasted. The provided shape is shown in FIG.
FIG. 5 shows an example of a separation type, which is divided into upper and lower parts. That is, the top wall 2, the curb wall 3 and the upper part of the back wall 4 are separated from other parts. Since the water flow inlet i and the flow path R following the inlet are in the curb wall 3 and the upper part of the back wall 4, the present invention can be applied even to the separation type as shown in FIG. 5.

As described above, in the gutter block, the entrance of the flow path where the running water from the road flows down cannot pass the plastic bottle, and the other flow paths are wide enough to pass the plastic bottle so that the road surface is not flooded. Can help prevent natural disasters.
