Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible membrane undulation weir, and more particularly to a flexible membrane undulation weir that is reinforced or repaired or has an external appearance patterned.

[0002]

2. Description of the Related Art A flexible membrane undulation weir is a floor, slope, etc. of a river or the like in a direction that traverses a flow such as a river with a flexible membrane covering such as a rubberized cloth forming a weir body. Attached to the floor of the enclosure, sending inflation medium such as air or water into the envelope to make the envelope expand and stand up, and discharge the expansion medium from inside the envelope to shrink and collapse the envelope. (See, for example, Japanese Patent Publication No. 40-11702 and Japanese Patent Publication No. 44-2371).

In order to reinforce this type of undulating weir, measures such as sticking a cushioning material to the inner floor surface of the weir or the outer floor surface of the weir and increasing the rubber thickness are taken. For repairs, a method is used in which a rubber stopper is attached to the repaired part to close the annulus, or a rubber patch is attached. The appearance of most weirs is either gray or black.

[0004]

[Problems to be Solved by the Invention] In this type of undulating weir,
Due to various factors such as the condition of the river and the location of the weir installation, unexpected stress concentration and flow may affect the weir, which may require reinforcement. In addition, it may be necessary to repair the weir due to damage caused by mischief or boulders.

In this case, it takes time and cost to reinforce or repair the entire weir. In addition, except for some of the large weirs, it is necessary to remove the weirs in order to perform treatment from inside, and thus it is necessary to perform treatment from outside.

There is no change in the appearance gray or black color. The present invention is a reinforced or repaired or patterned flexible membrane undulation weir developed to solve such problems.

[0007]

According to a first aspect of the present invention, a flexible film envelope forming a weir is attached to at least a river floor, and air or water is fed into the envelope to inflate and rise. In addition, reinforcement or repair or patterning of the appearance was performed by arranging a plurality of strip-shaped or tile-shaped flexible membrane materials in the undulating weir that was designed to discharge air or water from the inside of the envelope and cause it to collapse and collapse. The strip-shaped or tile-shaped
When there is one flexible membrane material in the river flow direction, it is a single substance

A second invention of the present application is to form a weir body.
Attach a flexible membrane envelope to at least the river floor to cover
Air or water is sent to the inside to inflate and stand up.

[0010]

According to the present invention, in a flexible membrane undulation weir, a potentially damaging portion or a damaged portion is covered with, for example, a strip-shaped or tile-shaped flexible membrane material having an appropriate size. It is characterized in that the reinforcement or repair site is partial.

According to the present invention, it is possible to reduce the time and cost by performing the partial treatment as described above, and when the room temperature curing adhesive (natural vulcanizing adhesive) is used, vulcanization by pressing is performed. It is possible to save work and improve workability.

Further, both ends of the flexible membrane material are tapered in the flow direction of the river water, and along the circumferential direction of the undulating weir, for example, the whole circumference or a part or all of the upstream side of the folding line. When it is attached to the, it can be prevented from peeling off due to water flow and falling material.

Further, in the present invention, since a plurality of strip-shaped or tile-shaped flexible film materials are arranged and adhered to each other, it is possible to easily repair them by simply replacing the film material at a location where damage or wear is severe (a large piece In the film material, it is necessary to replace all parts, but with the above configuration, only a part is sufficient).

If a strip-shaped flexible film material is used instead of a strip-shaped flexible film material, the number of repaired parts will be smaller and the time and cost will be considerably saved.

According to the present invention, the appearance of the weir can be made colorful in addition to the reinforcement or repair by adding a pattern to the flexible film material to be laminated, and from the viewpoint of environmental beautification. Is also preferable.

[0016]

EXAMPLES Examples of the present invention will be described below. Example 1 A flexible film material 1 such as a strip of rubberized cloth as shown in FIGS. 3 and 4 is adhered to a place where damage to the undulating weir cover 3 is likely or a damaged place as shown in FIGS. Stick with a drug etc. In FIGS. 1 to 4, 2 is a taper portion, 4 is a river bed portion, 5 is a river section, and arrows indicate the flow direction. The tapered portions 2 are provided at both ends in the flow direction as shown in FIG. 3 in order to prevent the film material from peeling off.

Embodiment 2 Further, in the case of a strip-shaped flexible membrane material, if there is a protective material 7 for the metal fitting 6 for fixing the covering of the undulating weir to the river floor as shown in FIG. If the upstream end 8 is hidden, peeling can be further prevented.

Embodiment 3 In the present invention, a tile-shaped (square-shaped) flexible film material 9 as shown in FIGS. 6, 7 and 8 may be used. An example is shown in FIG. At this time, the one not having the tapered portion shown in FIG.
The one having the taper portion 2 on the upstream side shown in Fig. 8 is attached to the upstream end side, and the one having the taper portion 2 on the downstream side shown in Fig. 8 is attached to the downstream end side. The taper treatment can prevent the film material from peeling off.

[0019]

As described above, according to the present invention, the reinforcement or repair time and the cost thereof can be saved. At the same time, it is possible to prevent peeling of the reinforcing material or the repair material.
