The present invention relates to, for example, a flexible rubber dam which is arranged to traverse a river or a river, and secures a low amount of water by standing and doping by injecting and discharging air. When the rubber beams are inclined and stood up, the breakage can be prevented to relieve and prevent damage such as tearing of the folds caused by the standing up and repetition of the rubber beams by reinforcing the folded and unfolded areas known as vulnerable parts. The present invention relates to a reinforcing structure of a flexible rubber dam.

In general, a steel self-conducting fence has been known as a fence for level control of a reservoir or agricultural / industrial inlet, a hydropower generating top, a water intake, an entertainment freshwater or an estuary seawater dam. However, such a steel fence is operated by a hydraulic cylinder or the like, maintenance operation is very difficult and it was impossible to install on a weak foundation.

Recently, water level dams, called so-called prefabricated flexible rubber dams, which are operated by direct supply of fluids such as air and water, and each of which is made of rubber sheets that are easy to install or maintain, have been developed and put into practical use. Such flexible rubber dams are effective in securing effective water storage and assembling and installing even in mountainous areas or in poor terrain conditions, and control the height of rubber dams by supplying fluids such as air and water according to the desired water level. Therefore, it attracts great attention as a dike fence. In other words, flexible rubber dams placed across rivers or other streams expand and stand by supplying fluid inside a rubber weir to prevent the flow of the river, and to prevent the closed rivers to flow downstream. The fluid filled inside is drained and shrunk.

In such flexible rubber dams, driftwood or sand or stones floating upstream and downstream with the river reaches the upper part of the rubber beam and rubs against the outer surface of the upper part. On the other hand, during the expansion of the flexible rubber dam, the large stones floating upstream and downstream due to heavy rains turn on the outer surface of the rubber beam toward the day and press and collide with the rubber beam, thereby causing wear, scratches, perforations, Damage caused by external forces, such as tearing, is caused on the outer surface of the rubber beam. On the other hand, a technique for embedding a fiber fabric reinforcement layer and a wire mesh reinforcement layer in each of the upper and lower sheets of the rubber beam to withstand the wear and damage has been proposed.

As an example of a rubber dam having a fiber fabric reinforcing layer and a steel wire reinforcing layer embedded in the upper and lower sheets, it is known by Korean Utility Model Registration No. 384407 (name: reinforcing structure of a rubber dam tube).

 According to Utility Model Registration No. 384407, in the reinforcing structure of a rubber dam tube composed of an upper sheet and a lower sheet of rubber material, and an end portion formed by joining the ends of these two sheets, the inside of the upper sheet and the lower sheet. A fiber fabric reinforcement layer and a wire mesh reinforcement layer are respectively formed in the fiber fabric reinforcement layer such that the reinforcement layer of the upper sheet is connected to the lower sheet reinforcement layer through the reinforcement portion, and the wire mesh reinforcement layer is the upper sheet reinforcement layer and the lower sheet reinforcement layer in the reinforcement portion. It provides a reinforcing structure of a rubber dam tube to be disconnected or to form the steel wire reinforcement layer only inside the upper sheet and the lower sheet, and the fiber fabric reinforcement layer is formed only inside the reinforcement part.

In the reinforcement structure of the rubber dam tube according to the Utility Model Registration No. 384407, when the rubber dam stands up, the fiber fabric reinforcement layer is rounded at the inner part of the reinforcement part, and the wire mesh reinforcement layer is extended to the reinforcement part. Not only does it reinforce the tube as a whole, but when the rubber dam is folded, the upper sheet and the lower sheet are naturally folded, and in the part where the tube is folded, it is protected by a thick thickening part, so that the folded part may be damaged. It is not there.

However, according to the reinforcement structure of the rubber dam tube according to the above-mentioned Utility Model Registration No. 384407, the occurrence of rust on the metal surface due to the long use of the metallic wire mesh reinforcement layer and the water through the through hole or the cut damage at the outermost side of the rubber beam Corrosion due to penetration occurs, resulting in degradation of the reinforcement layer such as the metallic wire mesh reinforcement layer peeling off from the rubber surrounding it. This lowers the durability of the rubber dam, which reduces the protective properties in the basic structure of the rubber dam tube and causes other undesirable factors.

In addition, in order to control the water level of the river, the rubber dam tube is repeatedly performed and standing, wherein the inside of the folded and unfolded portion of the rubber dam tube, especially the folded and unfolded portion is repeated in the standing and repeating of the tube As a result, aging is not only accelerated, but when scratches are generated on the folded and unfolded portions, stress is concentrated on the portions, and the portions are gradually opened, resulting in damage to the soluble rubber.

Accordingly, an object of the present invention is to reinforce the at least a portion of the inner side of the folded and unfolded portion of the flexible rubber dam, in particular, the folding and unfolding of the flexible rubber dam in order to solve the problems of the prior art. It provides a reinforcement structure of a breakage-resistant flexible rubber dam that improves the protection characteristics of the rubber dam against damage to the folds caused by repeated reinforcement. The reinforcement structure of the flexible rubber dam provides air injection and discharge. A part of the inner surface layer of the rubber beam which is folded and unfolded by means of a rubber sheet and a reinforcing fiber layer is achieved by attaching a reinforcing member made of a material selected from a rubber sheet in which the rubber sheet is embedded in the steel width direction.

Other objects proposed by the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the reinforcing structure of the anti-damage flexible rubber dam according to the present invention for achieving the above objects, the upper and lower rubber sheets, and through the dents provided by the joining of one end of these two rubber sheets In the flexible rubber dam which is made of reinforcing fiber layers embedded in the upper rubber sheet and the lower rubber sheet and is disposed in the width direction and stands up or covered by air injection and discharge,

Reinforcing members having a certain thickness and area made of a material selected from rubber sheets and rubber sheet with reinforcing fiber layers embedded therein are bonded in the width direction and folded in half by the injection and discharge of air. Characterized in that it is to be expanded.

Optionally, the reinforcing member is characterized in that both ends of the reinforcing member is adhered to a part of the inner surface of the toothing portion so that one portion of the reinforcing and folding portion is spaced apart from the inner surface of the toothing portion.

In this way, by reinforcing the reinforcing member made of a rubber sheet or a rubber sheet embedded with a fiber layer on the inner surface of the rubber bent portion in the width direction of the reinforcement, the landfill environment of the conventional metallic wire mesh reinforcement layer is changed and the time passes. The degradation of durability due to structural damage such as rust, corrosion, and peeling caused by rust is prevented, and the concentration of stress due to aging and scratching of the inner surface of the glands due to the standing up and repeating of the rubber beam is used as the reinforcing member. You can prevent it.

And, there may be a plurality of embodiments of the present invention, the following will be described in detail for the most preferred embodiment.

Through this preferred embodiment it is possible to better understand the objects, features and advantages of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the reinforcing structure of the flexible rubber dam to prevent damage according to the present invention.

1 is a partial cut cross-sectional view of an embodiment of a flexible rubber dam according to the present invention, Figure 2 is a partial cut cross-sectional view showing a state in which the reinforcing member is bonded to the inner surface of the gushing portion of the flexible rubber dam of FIG. 3 is a cross-sectional view illustrating the enlarged portion of the flexible rubber dam in the standing state of FIG. 2.

The rubber beam 100 constituting the rubber dam of the present invention is made of a belt-shaped rubber tube, and in the method of manufacturing the rubber beam 100, as shown in FIG. 1, first, made of metal or thick paper. A flat plate-shaped demolding member 121 is prepared.

Then, the strip-shaped first reinforcing fiber layer 123a made of a thin unvulcanized first supplemental rubber sheet 122a and a synthetic fiber or cotton fiber such as nylon and polyester with the prepared release member 121 therebetween. In the order of the unvulcanized second supplementary rubber sheet 122b, the second reinforcing fiber layer 123b, the unvulcanized third supplementary rubber sheet 122c, and the third reinforcing fiber layer 123c, the both ends thereof are matched in half. Fold and stack.

As described above, one end portion of the laminated laminate is thicker than the other end portion and is longer than the length of the folded state of the third reinforcement fiber layer 123c, and the fourth and fifth reinforcement fiber layers 124 are respectively formed in a strip shape. ) 125 is laminated with the unvulcanized upper and lower rubber sheets 110 and 120 embedded therein. At this time, one end portion of the upper and lower rubber sheets 110 and 120 having a thicker thickness than the other end portion is sufficiently protruded from the folded portion of the third reinforcing fiber layer 123c, and the other end portion is thinner than the one end portion. Is laminated so as to coincide with both ends of the third reinforcing fiber layer 123c.

Thereafter, the laminates are pressed and thermally vulcanized in a vulcanizing press and then detached from the first supplemental rubber sheet 122a such as a thin metal or non-stick thick paper, as shown in FIG. 2. Similarly, one end of the upper and lower rubber sheets 110 and 120 is integrally molded with a rubber beam 100 having an additional portion 126 protruded out as a bookbinding site due to thermal vulcanization.

Thereafter, at least a portion of each of the upper and lower portions of the inner surface rubber portion of the rubber part 100 of the rubber beam 100, an unvulcanized rubber sheet and an unvulcanized rubber sheet in which a reinforcing fiber layer such as cotton fiber or nylon or polyester is embedded The reinforcing member 128 having a predetermined thickness and area made of a material selected from is padded in the width direction and bonded by thermal vulcanization in the same manner as described above. At this time, the reinforcing member 128, as shown in Figures 2 and 3, it is preferable that only the two ends to be bonded so as to be slightly spaced apart from the inner surface of the gushing portion 126 when the rubber beam 100 is folded and unfolded. .

The rubber beam 100 manufactured as described above is positioned in the folded portion 126 in the downstream state and the other end of the anchor bolts 30, 40 and clamping plate 10, 20 buried arranged in the width direction By airtight fixing to the bottom of the concrete.

And the rubber beam 100 is always flat to the bottom surface of the bottom concrete in the doped state, that is, folded state, as shown in Figure 2, the cutting damage by the turning stone hardly occurs, wear resistance and durability is strong Can be increased without disturbing the flow of.

Since the rubber beam 100 is embedded in almost all of the rubber beams 100, the reinforcing member 128 that reinforces the rubber beam 100 as a whole and is padded and adhered to the inner surface of the gushing portion 126 is bonded to the rubber beam 100. Because stress concentration of the inner surface of the gushing portion 126 is dispersed, the stress is not concentrated on the inner surface of the gushing portion 126 even though the rubber beam 100 repeats the doping and standing. Breakage is prevented. In particular, when the rubber beam 100 is folded and unfolded, the reinforcing member 128 is naturally folded and unfolded together with the upper rubber sheet 110 and the lower rubber sheet 120. And since the thickness of the dent part 126 is the thickest in the overflow position of the river by the reinforcing member 128, the cut resistance effect is the largest.

Therefore, the cut resistance of the grate part 126 is good in the area which is likely to cause cutting damage due to the collision of wood or floats drifting in the river, or the area where water is discharged and fresh water periodically, and durability will be increased.

On the other hand, as a comparative example, due to changes in the landfill environment of the metal wire mesh reinforcement layer, that is, structural damage such as occurrence of rust, corrosion, and peeling over time, and the rise of rubber beams and repetition Unlike the breakage of rubber beams due to the rapid progress of aging and stress concentration on the inner surface of the grate part, the present invention has a reinforcing member attached to the inner surface of the grate part in the width direction, It is possible to further extend the life of the rubber dam by preventing the concentration of stress due to aging and scratching of the inner surface of the gnat part due to the repeated standing and doping.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.
