MAINTENANCE STRUCTURE COMPRISING WATERWAY FOR DAM AND RESERVOIR STRUCRUTE USING THE SAME}

The present invention relates to the construction art, and more particularly, to a maintenance structure of a dam.

Various dams are installed to prevent water flow by preventing river flow or to prevent rapid increase of downstream flow due to flood.

In the area of the reservoir structure formed by such dams, various contaminants, small streams such as gravel and coarse sand, and the like are introduced and contaminated by the floodwater. To prevent this, a porous channel is installed in a permeable structure such as a gabion.

In this way, since the porous channel is formed by the porous media having a gap, in the non-flooding period where the amount of water flowing in from the upstream is small, the water is purified while flowing through the gap of the porous channel, without overflowing the porous channel.

In the Flood, small streams of gravel and coarse sand coming from upstream with various contaminants are filtered out of the porous channel. Relatively less contaminants are collected on the upstream side of the porous channel.

Thus, contaminants and sorbate trapped in the porous channel should be removed periodically to restore its purification function.

On the other hand, as the water flowing from the upstream increases, surplus floating sand, such as sand of small size, included in the water flowing through the porous channel, flows into the reservoir along with the overflowing water.

In order to capture such surplus floating sand, a floating sand overflow prevention jaw may be additionally installed downstream of the porous channel.

Floating yarn overflow prevention jaw blocks the flow of surplus floating sand that has flowed through the porous channel, and thus floating sand is collected at the lower side of the upstream side of the overflow blocking jaw.

Since the porous channel and the floating sand overflow barrier block the flow of the river, the flow velocity becomes faster due to the overload in the porous channel and the floating stream overflow barrier during flooding. It is becoming. In addition, due to the overload described above, there is a problem that the lifespan is shortened due to a lot of damage and breakage of the porous channel, the floating yarn overflow prevention jaw.

It may be characterized in that it is installed to form a water passage through which the river 2 can flow.

That is, the block 12 filters the contaminants, the small sands, the floating sands, etc. flowing to the water storage region, and also allows the flow of the river 2 through the water passage.

Therefore, the contaminants, streams, floats, and the like caught by the block 12 are deposited on the upstream side of the block 12 so that the contaminants, the streams, the floats, and the like can not be prevented from flowing into the water storage region. In addition, the flow of the stream 2 is received by the block 12, but because the flow through the passage can be prevented from overloading the flow in the block 12, according to the flow rate due to the overload of the flow The increase can be prevented and the damage of the block 12 due to the overload of the flow can be reduced. In addition, it is possible to induce vortex by securing a water passage, so separation and precipitation of contaminants can be made more easily.

It can be installed to be inclined along the flow direction of the river (2) toward the opposite end from. In this case, as the block 12 is installed to be inclined with respect to the lateral direction of the river 2, the sediments are sedimented and deposited sequentially, so that the sediments are separated by type, so that high-quality sand and the like selected carefully can be obtained. Water can easily be diverted from the stream.

Sixth, each block 12 may be formed entirely in a straight line as shown in Figs. 6A to 6F, or at least a part may be curved as shown in Fig. 6G. In the latter case, the block 12 is provided at the edge side of the stream 2 with respect to the transverse direction of the stream 2 so that the stream 2 can be smoothly installed to correspond to the flow of the river 2. At least a portion may be curved in order to bend along the flow direction of the stream 2 toward the opposite end from the.
