Description

[0001]
[Industrial applications]
The present invention relates to a cover for a side gutter or a transverse gutter for draining water, and more particularly to a low-cost and highly safe concrete gutter for replacing a grating.
[0002]
[Prior art]
The present applicant filed an application for this type of concrete gutter on June 13, 1994. Although the present invention has a water inlet in the width direction of the groove lid, since the water inlet does not extend over the entire width in the width direction, water flowing from the road flows between the groove lid and the groove wall, and the groove lid and the groove wall. Sand and dust clog in between. As a result, the water crosses the boundary between the groove lid and the groove wall and reaches the upper surface of the groove lid. Therefore, the water is not sufficiently taken in at the water entrance, and the water may flow backward toward the road.
[0003]
[Problems to be solved by the invention]
The overflow water flowing from the road at the side gutter for draining and the crossing gutter lid flows directly from the gutter wall to the water entrance of the concrete gutter to prevent the clogging of dust and dirt between the gutter and the gutter wall. To prevent.
[0004]
[Technical means]
A water inlet 2a is provided on the upper surface, and has a downflow path 2b inclined from one side to the other side, and an upper side surface of the downflow path 2b is connected to the water inlet 2a and opened to form an open side surface 2o. Using a synthetic resin drain body 2 composed of an inflow portion 2x and an outflow cylinder 2y connected to the lower surface of the lower end of the downflow path 2b of the inflow portion 2x.
[0005]
The drainage bodies 2 and 2 are buried in the width direction of the concrete groove cover 1 with the outflow cylinders 2y and 2y facing each other inside, and the open side surface 2o of the inflow portion 2x is exposed to the side surface of the concrete groove cover 1. The concrete gutter is embedded.
[0006]
[Action]
When the water overflowing from the road gets over the groove wall, it flows directly into the open side surface 2o of the water inlet 2a of the groove cover, so that the gap between the groove wall 3 and the groove cover 1 is not clogged with dirt and dust.
[0007]
【Example】
FIG. 1 is a perspective view of a drain body 2 according to a first embodiment of the present invention.
The draining body 2 has a piston-like side, and is made of synthetic resin. Then, they are opposed to each other with the piston-shaped base inward, and embedded in the groove cover 1.
[0008]
As shown in FIG. 1, the drain body 2 includes an inflow portion 2x and an outflow cylinder 2y formed on the lower surface on one side thereof.
The inflow portion 2x has a water inlet 2a reinforced by a reinforcing rib r and a flow-down passage 2b inclined from the outside to the inside. At the upper end of the downflow path 2b, a side surface that is connected to the water inlet 2a and contacts the groove wall is opened to be an open side surface 2o.
[0009]
An outflow cylinder 2y is formed on the inner lower surface of the inflow portion 2x of the drainage body 2.
Then, the groove cover 1 is embedded with the open side surface 2o of the drainage body 2 opened to the side surface of the concrete groove cover 1 as shown in FIG.
Therefore, the open side surface 2o comes into direct contact with the groove wall 3.
[0010]
Since the present invention is configured as described above, the water flowing from the road as shown in FIGS. 3 and 4 directly flows into the open side surface 2o of the drainage body 2 as shown in FIGS. 2b flows down from the outflow cylinder 2y into the groove.
[0011]
The smaller the distance between the drainage bodies 2 is, the less the dust and dirt carrying water that flows into the drainage bodies 2 are rarely caught between the groove walls 3 and the groove lids 1. 2 cannot be made too narrow.
Actually, it is considered that a large proportion of the water flowing into the space between the drainage bodies 2 flows into the open side surface 2o of the drainage body 2 due to the water force.
[0012]
Next, a second embodiment shown in FIG. 5 will be described.
The second embodiment differs from the first embodiment in that an integrated drainage body 2 is used.
[0013]
That is, the drainage body 2 of the second embodiment has the following configuration.
That is, the water inlet 2a is provided at the outer end of the upper surface, and the flow path 2b is inclined inward from the outside to the inside.
[0014]
Further, an inflow portion 2x which is open at the upper end outer surface of the flow-down passage 2b by being connected to the water inlet 2a to form an open side surface 2o;
[0015]
The drainage body 2 made of synthetic resin is used, which is composed of an outflow cylinder 2y connected to the lower surface of the lower end of the downflow path 2b of the inflow section 2x.
[0016]
Then, the drainage body 2 is embedded in the width direction of the concrete groove lid 1, and at this time, the open side surface 2 o of the inflow portion 2 x is exposed and embedded in the side surface of the concrete groove lid 1.
[0017]
In the second embodiment, similarly to the first embodiment, the water flowing from the road directly flows into the open side surface 2o of the drainage body 2, flows down the downflow path 2b, and flows out of the outflow cylinder 2y into the groove.
[0018]
【The invention's effect】
Since the water flowing into the groove from the road flows directly into the open side surface 2o of the draining body 2, the amount of water flowing into the gap between the groove cover 1 and the groove wall 3 is reduced to the matching width, and the groove cover 1 and the groove are reduced. The amount of earth and sand and the like clogging between the walls 3 is greatly reduced, and the drainage efficiency is significantly improved.
