Description

 {Assembly Penetrating Type Check Dam}

More particularly, the present invention relates to a transmission check dam capable of simplifying the overall structure of a ground supporting part buried under the ground and preventing a loss of filler due to a flow rate flowing from the upstream to the downstream, In addition, the present invention relates to a prefabricated transmission type dam capable of reducing the construction cost by reducing the overall construction period.

In general, check dam such as Sambang Dam is a civil engineering structure installed to prevent earthquakes and rocks from flowing downward along the rapids because the rapids dug through the riverbed in the valley where the river has a large slope and cut down both sides of the mountain to cause landslides .

The concrete sidewall dam is most commonly used for the sidewall dam installed for the prevention of floods such as mountain valleys, but it is a sideway dam for the purpose of water storage and storage, and is installed on a large scale on the downstream side of the river.

In addition, a steel landslide dam, such as the Bertrath Sambang Dam and Slit Sambang Dam, causes a landslide to occur in the upstream of the mountain valley so that the roots extracted from the river float down and are caught in the dam, thereby preventing the change of the flow path due to the loss of the driftwood or rock, Thereby preventing damage to the user.

The Korean Utility Model Registration No. 0320064 (2003.07.22) of the Republic of Korea registered a concrete structure in which a concave portion is formed in a region where the flow of water is anticipated and which is installed on the edge and bottom of the canyon, and the inclined shaft, the horizontal shaft and the screen material are installed in the concave portion And a supporting shaft which is composed of a supporting shaft and a supporting shaft connecting the inclined shaft and the supporting shaft.

Such a conventional Bertrice square dam must first be constructed with a concrete structure having a foundation corresponding to a foundation of a floor, a shoulder portion connected to a canyon, and a side wall extending therefrom, and having a concave portion on which a steel structure is installed.

However, since these concrete structures are constructed through the foundation construction, formwork construction, concrete casting and curing steps sequentially in the gorges, there is a limitation in reducing the construction cost due to the long construction period.

In addition, it is difficult to construct eco - friendly four - way dams because they are recognized as pollutants causing environmental pollution.
