The present invention relates to a device and a method for preventing the folding of the slope of the rubber beam, and more specifically, in consideration of the rubber tube width and slope angle during construction, the rear end of the rubber tube (upstream side) in close contact with the concrete bottom, By supporting the fold prevention jig and the front end of the rubber tube (downstream side) is raised to a certain height, when the rubber beam is standing up, the fold of the slope portion does not occur, it can improve the durability and wear resistance of the rubber beam, The present invention relates to a device for preventing the folding of the slope of a rubber beam to make the waterside space beautiful.

Generally, underwater beams are a kind of water barrier fence installed in the water for the purpose of agriculture, industrial water intake, water intake, water freshening for seawater or seawater dam in the estuary, and recently, high-strength rubber tubes are installed in the water. Rubber dams that operate by supplying a gas such as air into the tube have been developed and widely used.

In other words, when the gas is supplied to the tube inside the rubber dam, the tube stands and blocks the waterway, and when the gas is discharged, the tube coats the river bed and opens the waterway.

Such a rubber dam is a type of undulating movable beam, which is usually installed across a river. When a certain water level is reached, the rubber dam automatically discharges gas inside the rubber dam to allow the rubber tube to be inflated to the river bed. It has the advantage of not affecting it at all.

In addition, its use is increasing because it is easy to assemble and install in mountainous areas or places where terrain conditions are not good, and the height of the rubber dam can be easily adjusted according to the desired water level.

However, the rubber dam has a problem that the tube is easily torn by the external impact. In particular, since the rubber tube has to repeat the standing and standing, the folding portion of the tube is bound to be very weak structurally.

Therefore, the so-called book-end type rubber dam is an improvement of the structure of the tube fold when the rubber dam is covered.

The bookend type is a form of a gushing portion that protrudes out at a portion where the upper sheet and the lower sheet of the rubber tube meet, like a book binding portion. This bookend type rubber dam can greatly reduce the breakage rate of the rubber dam because the folded portion of the tube is protected by the reinforcement part during the coating.

Meanwhile, the rubber tube used to install the rubber dam is made of a rubber material having elasticity. In this case, the rubber tube is molded by embedding and laminating a fabric reinforcement layer made of, for example, a high strength synthetic fiber to increase its strength.

However, the fiber fabric reinforcement layer is excellent in flexibility, but the strength is weak, and the dams are often damaged by driftwood or stalactites, especially when the tube is standing.

In order to supplement the problems of the conventional fiber-reinforced rubber dams, efforts have been made to reinforce the strength by forming a reinforcing layer made of steel wire, that is, steel wire net, in the rubber tube. As a result of the repeated standing and doping, the wire mesh was disconnected at the portion where the rubber tube was folded, and there was a problem in that the portion was easily torn due to rust or damage to the tube.

Moreover, it has been known until now that it is structurally impossible to manufacture rubber tubes reinforced with steel wires in bookend type rubber dams.

In order to improve the above problems, Korean Utility Model Registration No. 20-0384407 has a fiber fabric reinforcement layer and a wire mesh reinforcement layer formed in the upper sheet and the lower sheet, respectively, wherein the fiber fabric reinforcement layer is a top sheet through the bent portion A reinforcing structure of a rubber dam tube is disclosed so that the reinforcing layer and the lower sheet reinforcing layer are connected to each other, and the wire mesh reinforcing layer is such that the upper sheet reinforcing layer and the lower sheet reinforcing layer are disconnected at the glands.

However, the folded portion of the rubber tube occurs at the place where the inclined surface is in contact with the concrete steel floor on which the tube is installed during the coating (see FIG. 8), and is formed along the circumferential direction of the rubber beam during the ups and downs (see FIG. 9). .

That is, as shown in FIGS. 10 and 11, the crimping and unfolding are repeated in the fold-folded portion 101 of the rubber tube 100 as the doping and ups and downs are repeatedly performed, thereby embedding the rubber and the rubber. The peeling phenomenon of the reinforcement cloth (reinforcement net) is generated, and accordingly, the aging speed is increased, which not only adversely affects the durability and wear resistance of the rubber dam, but also the rubber crimping phenomenon in the folded part is prolonged for a long time, so that cracks and damage are severe. Shorter replacement periods can lead to higher investment costs and shorter lifetimes.

In addition, the folded portion 101 may be a factor that inhibits the composition of the beautiful river landscape against the original purpose of installation.

The present invention has been made in view of the above point, in consideration of the rubber tube width and slope angle during construction, the rear end of the rubber tube (upstream side) in close contact with the concrete lower bed, the support jig for preventing the folding on the edge of the slope and the rubber Since the front end (downstream side) of the tube is raised to a certain height, it is possible to improve the durability and abrasion resistance of the rubber beam by making the folding part of the slope when the rubber beam rises, thereby improving the waterfront space.
