Abstract

A corrugated steel plate protection type rubber dam is provided to promote the effective management of water resources by preventing the decomposition of water kept in store and the accumulation of soil on the upper reaches of a dam, to preserve an ecosystem by installing a simple fishway, and to reduce the production costs of a panel and to prevent the water leakage caused by deformation by having large bearing capacity per unit weight and low strain against temperature difference in wintertime and summertime. A corrugated steel plate protection type rubber dam, for controlling the water level according to the operation of an air bag rising or overturning with pneumatic pressure, comprises an air bag(1), a corrugated steel plate panel(3-1) stood erect or turned over by the air bag, a band or a rope for controlling an opening and closing unit fixed or supported to the air bag or the panel to be pulled or loose, a drainageway connecting the upper reaches and the lower reaches of a dam, and an opening and closing unit installed to the drainageway. The corrugated steel plate protection type rubber dam enables to discharge deposits like soils accumulated on the bottom and bottom water gathered in the bottom to be decomposed easily through the opening and closing unit, without discharging the whole quantity of water kept in store, contrary to the existing rubber dam, and to function as a fishway with the drainageway connecting the upper reaches and the lower reaches of the dam.

Generally, various types of underwater beams are installed as weirs such as agricultural / industrial intakes, taps for water supply, and fresh water for environmental protection.

 Currently, about 18,000 underwater beams are installed in Korea, and most of them are concrete underwater beams. Most of the underwater beams installed in rivers do not fully function as sediment.

Recently, many new rubber dams have been newly installed or replaced. The rubber dam controls the water level by supplying and discharging air to the airbag, which is a closed rubber tube, by standing up or overturning the steel panel, which stands up and coats integrally with the airbag or airbag.

The steel panel described above is made of flat iron plate, which is highly deformed due to external impact or seasonal temperature changes.

This method eliminates the sediment accumulated upstream by periodically flooding the entire floodgate and discharging all the stored water, but the hassle of having to throw away all the waste water and warning the flood downstream every time it is discharged. There is this.

In addition, about 10% of the underwater beams are installed in Korea, and more than 99% are concrete-pooled or waterway-type. They also become paralyzed when soils accumulate, and most of the fish are discarded. There is a fish operation that does not have such a problem, but there is a lot of installation and maintenance costs, so it is not suitable for small underwater beams, such as rivers in Korea.

In order to solve these problems, the invention of the title prevents the decay of the stored water and prevents the sediment of sediment upstream of the underwater stream to promote the efficient management of water resources, and install a simple fishery to facilitate the preservation of the ecosystem.

Corrugated steel sheet has a larger bearing capacity per unit weight than flat steel sheet, and the strain rate of temperature difference in winter season is smaller, which reduces the manufacturing cost of panel and prevents leakage due to deformation.

There are many rubber dams that control the water level by standing or doubing airbags by supplying and discharging air to sealed airbags from various types of submerged waterbanks such as agricultural / industrial intakes, taps for water supply, and desalination for environmental protection. Or it is being replaced.

This invention relates to a corrugated steel panel (3-1), which is erected or spilled by an airbag (1) and its airbag, in a rubber dam that adjusts the water level according to the operation of an airbag standing up and insulated by pneumatic pressure, and the airbag or Corrugated steel sheet protection type consisting of opening and closing adjustment band (4) or rope fixed or reliant on the panel, pulled or slowed down, drainage passage (6) connecting upstream and downstream of the dam and opening (5) installed in the drainage passage The invention relates to a rubber dam.

Unlike conventional rubber dams, it is possible to preferentially release sediment, such as earth and sand, accumulated on the floor and perishable low-level water without discharging the entire amount of stored water, and to connect the upstream and downstream of the dam. Acts as an adobe.

Corrugated steel sheet has a larger bearing capacity per unit weight than flat steel sheet and has a smaller strain rate with respect to the temperature difference during the winter season. Therefore, if the steel panel is made of corrugated steel sheet, the manufacturing cost of the panel is reduced and the leakage by deformation is prevented.

 1 is a perspective view of a rubber dam equipped with a panel 3-1 of corrugated steel sheet.

Both ends of the panel of corrugated steel sheet are covered with rubber packing (8), so that the watertightness is improved by precisely contacting and rotating the steel plate installed on the dam side of the embankment.

If a transparent plate such as tempered glass is used instead of the steel plate installed on the dam side of the dam, the underwater state of the upstream side of the dam can be examined inside the transparent plate.

Corrugated steel plate has higher bearing capacity and less strain against temperature difference than flat steel plate, thus reducing panel manufacturing cost and preventing leakage due to deformation.

2 is a state in which the airbag 1 and the airbag protection corrugated steel panel 3 for standing up and receiving the air are supplied by a pneumatic supply device not shown on the lower concrete 7 to maintain the water level upstream. This is an embodiment of the rubber dam which pulls the opening and closing adjustment band 4 fixed to the airbag protection panel tightly, and operates the opening and closing opening 5 to block the drainage passage downstream.

Changing the structure and installation of the bands and openings may block them upstream of the rubber dam.

FIG. 3 is a view of a state in which the band is stretched by opening the opening and closing port by lowering the height of the airbag and the airbag protection panel by leaking air (reducing the pneumatic pressure) in the state of FIG. 2.

It accumulates in the bottom layer, which accumulates in the bottom layer, as well as sediments such as earth and sand.

Unlike conventional rubber dams, the sediment, such as earth and sand accumulated on the floor, and the sedimentary low-level water that accumulate on the floor are preferentially discharged without having to discharge all of the stored water. In addition, it can also serve as a fishery.

Since corrugated steel has a larger bearing capacity per unit weight than flat steel, less steel is required, and there is no leakage due to deformation of the panel because the strain against the temperature difference is small in winter.
