Large depth channel structure with river flow regulating function {STRUCTURE OF THE DEEPLY UNDERGROUND WATERWAY FOR ADJUSTING RIVER FLOW}

The present invention relates to a large depth channel structure having a river flow control function, in the dry season effectively supplies the flow rate required for the river, in the rainy season close to the river to prevent flooding of the river (for example 40-50 m underground This technology relates to a large depth channel structure having a river flow control function installed on the

Large depth is defined as the marginal depth which is not expected for the landowner's normal use and does not interfere with general land use due to the installation of underground facilities.

As part of solving traffic problems between cities, which have been recently complicated, roads or railways using such a concept of a large depth have been developed.

In other words, to solve the traffic problem by using the road or railroad on the ground, there is a space constraint on its installation, so the effort to solve this problem by developing the underground space 40 ~ 50m below the ground began.

On the other hand, the utilization of the space on the large depth can also be used as a way to solve the problems related to the quantity control of the river.

Most of small and mid-sized rivers in Korea have a steep slope due to the large elevation difference in the upper part of the river, so during the dry season, it is necessary to secure the flow rate, which is the minimum flow rate required for the stream. Emissions cause river overflows.

Therefore, in order to solve the problem of river flow regulation, the need for development of a channel with a depth concept that can be installed adjacent to a river is emerging.
