Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weir structure for a waterway.

[0002]

[Prior art]

 Conventional dam plates are made of wood veneer, a veneer surrounded by a steel frame, or a reinforced concrete plate. The weir plate made of wood absorbs water, expands, and deforms, which may make opening and closing difficult. In addition, a wooden veneer surrounded by an iron frame and a weir plate made of reinforced concrete are heavy, and opening and closing work is difficult, and it is necessary to use a machine to raise and lower the structure, which causes the device to increase in size. was there.

Further, since wood and iron frames are corroded by water, their service lives are short and maintenance and replacement are expensive. Moreover, since the conventional weir plate is simply inserted from above into the insertion groove to be attached, it becomes difficult to insert it when the weir plate is deformed, and a gap is created between the weir plate and the water leakage from here, resulting in a water blocking effect. It was bad.

[0004]

[Problems to be solved by the device]

 The present invention eliminates the above-mentioned drawbacks and provides a water channel weir structure that is not deformed or corroded by water, has excellent durability, is lightweight, is easy to open and close, and has an excellent water blocking effect.

[0005]

[Means for Solving the Problems]

 According to the present invention, a plurality of rollers and balls are longitudinally spaced along the both side edges of the part of the dam plate body made of plastic or glass fiber reinforced plastic that is inserted into the insertion groove formed in the concrete channel. To form a weir plate, and a strip-shaped water stop valve made of elastic material near the upstream side of the insertion groove on the inner wall surface of the water channel, so that the downstream side is crimped to the side surface of the weir plate. It is characterized by being installed in the direction.

[0006]

[Action]

 In the water channel weir structure of the present invention, the free end side of the water shutoff valve is linear due to elasticity when the weir plate is pulled out from the insertion groove of the water channel. When blocking the water in the waterway Hold the weir plate and insert the roller and ball sides downstream and insert both ends into the waterway insertion groove, and the rollers and balls will rotate while being guided by the wall surface of the insertion groove. Therefore, it can be inserted smoothly with less frictional resistance. With the weir plate inserted in the insertion groove, the water shutoff valve crimps the upstream side surface of the weir plate with water pressure to prevent water from leaking from the insertion groove to the downstream side, and to stop it securely. Can be watered.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, 1 is a weir plate, and this weir plate 1 is formed along the outer edge of one side surface 3a of the weir plate main body 2 formed of a rectangular fiber-reinforced plastic (FRP) as shown in FIG. A rectangular frame-shaped rib 4 is integrally projected. Further, as shown in FIG. 1, longitudinal ribs 5 and 5 are provided at intervals inside the ribs 4 and 4 along the both side edges, and between these ribs 4 are rotatably supported by a support shaft 6. A number of plastic rollers 7 are mounted longitudinally spaced.

As shown in FIG. 1, an intermediate portion of one side surface 3a to which the roller 7 of the barrier plate main body 2 is attached projects forward and a hollow portion 9 is formed between the side surface 3b and the other side surface 3b. The portion 9 is filled with a filling material 10 such as urethane home. Also, as shown in FIG. 3, elongated rib-shaped handle holes 11, 11 are formed in the upper rib 4 of the barrier plate main body 2, and the lower rib 4 is made of rubber or the like as shown in FIG. The formed packing 12 having cushioning properties is bonded with an adhesive.

Further, in FIG. 1, reference numeral 14 is a water channel made of concrete, and insertion grooves 15, 15 into which both ends of the dam plate 1 are inserted are formed in the vertical direction on both inner wall surfaces 14 a 1, 14 a. Further, a band-shaped water stop valve 16 formed of an elastic material such as a rubber plate is attached to the inner wall surfaces 14a, 14a near the upstream side of the insertion groove 14. In this mounting structure of the water shutoff valve 16, nut anchors 17 are vertically embedded in the inner wall surface 14a of the water channel 14 at a predetermined interval, and the upstream side of the water shutoff valve 16 is aligned with the nut anchor 17 ... As shown in Fig.5, in the state that it is projected to the insertion groove 15 side, stack the plastic retainer 18 and press it from the side, and fix it by screwing it onto the nut anchor 17 through the stainless bolt 19 from above. The one that is projected to the insertion groove 15 side is free.

When the barrier plate 1 is pulled out from the insertion groove 15, as shown in FIG. 5, the free end side of the water shutoff valve 16 is linear due to elasticity, and water 20 flowing through the water channel 14 is discharged. Flow is not hindered. Further, when blocking the water 20 in the water channel 14, the hand is lifted by passing through the handle holes 11 and 11 opened at the upper part of the weir plate 1, and the rollers 7 are directed to the downstream side, and both sides are raised to the insertion grooves 15 and 15. Insert from At this time, if the upper portion of the straight stop valve 16 is bent inward and inserted into the side surface 3b of the dam plate 1, the roller 7 rotates while being guided by the wall surface of the insertion groove 15. Therefore, the weir plate 1 has a low frictional resistance and can be inserted smoothly.

As shown in FIG. 4, the bottom of the barrier plate 1 is gradually upstream because the packing 12 is in close contact with the inner bottom surface 14 b of the water channel and the water shutoff valve 16 is in close contact with the upstream side surface 3 b of the barrier plate 1. Water 20 collects on the side. As shown in FIG. 6, when the water level rises, the water stop valve 16 is pressed against the side surface 3b of the weir plate 1 by water pressure to prevent the water 20 from leaking from the insertion groove 15 to the downstream side. The water can be stopped reliably. When the weir plate 1 is removed and the water channel 14 is released, the roller 7 can also be easily pulled out by rotating the roller 7 by pulling it from the insertion groove 15 by hand through the handle hole 11.

It should be noted that various heights of the barrier plate 1 may be prepared according to the water level at which the water is stopped. Further, instead of the roller 7, a structure in which a ball is rotatably attached like a ball caster may be used.

[Effect of device]

 As described above, according to the water channel weir structure according to the present invention, since the weir plate is formed of plastic or FRP, it is not corroded or deformed by water, has excellent durability, is economical, and is lightweight. Since rollers and balls are attached to both ends of the dam plate inserted into the insertion groove, it is possible to smoothly open and close the water channel such as inserting and pulling it out. In addition, a water shutoff valve attached to the inner wall surface of the water channel is crimped by water pressure on the upstream side surface of the weir plate, so that a reliable water shutoff effect can be obtained.
