Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a float-

The present invention relates to an elevating type flood prevention wall structure, and more particularly, to an elevating type flood prevention wall structure capable of reliably maintaining airtightness at the time of ascending and descending, providing convenience at the time of construction, Wall structure.

As the urbanization progresses, the environment of rivers has been changed to the maintenance of reservoirs and slopes, the linear maintenance of river basins, and the construction of river banks for the purpose of flood communication.

Especially in urban areas, the maximum water flow width is secured with the ability of water flow at the time of flood. Therefore, the habitat for flora and fauna is disappearing as the river environment is improved, and the entire width of the river is used as a reservoir .

In general, when urban rivers are located downstream, flood levels rise in the rainy season due to the accumulation of long-term soil and wastewater, resulting in floods in the rainy season.

In order to prevent the flood damage, it is necessary to buy land around rivers to build a bank, but as a reality, buying or accepting densely populated houses and land in order to build a banking site is expected to incur astronomical compensation expenses and complaints In fact, it is impossible to promote.

As described above, concrete flood walls are installed on the urban river basins in consideration of the fact that the embankment can not be constructed in urban river basins. However, this is fundamentally obstructing access to the nearby main river and rivers, It is a reality that it does not get the big response because it does not fit the stream which prefers natural river of.

The above-mentioned viewpoints can be exemplified by the "elevating steel multi-level flood prevention wall" (hereinafter referred to as "prior art") of the registered patent No. 10-1359482.

The prior art has a first movable part composed of a first movable plate which is lifted and lowered by a first movable unit inserted in a receiving part inside a foundation structure and a second movable plate lifted and lowered by a second movable unit coupled to the first movable plate, And a second movable part composed of a second movable part.

However, in the prior art, since the first and second movable plates are lifted and lowered from the foundation structure, airtight means for preventing inflow of water or foreign matter is not provided, and the operation after the elapse of a long time can be hindered.

Particularly, in the prior art, when a failure or an abnormality occurs in any one of the first and second movable means for lifting the first and second movable plates, all of the first and second movable plates together with the base structure are lifted from the bank or the slit There was a problem that a large construction to be replaced was necessary.
