Description

Gate extended overpass and flood prevention wall {A gate extended overpass and flood prevention wall}

The present invention is usually laid down and used as a passageway, but when overwater such as flooding is expected, it is erected to prevent damage from overwater. It relates to a gate extension type overpass and flood barrier that enables the installation of a high barrier by using space.

In order to prevent disasters caused by overturning waves occurring in port facilities, commercial facilities, private houses, etc. due to increased inundation of inland areas in port areas due to sea level rise and invasion of high waves due to climate change, standing in the land areas in existing ports By installing an overflow barrier, the support is usually laid down with a hydraulic cylinder to keep the gate lying down, while passing to the upper side of the lying gate. By erecting a gate and erecting a gate, damage from the overflow is prevented.

In this overcrowding prevention wall, a hydraulic cylinder is installed on the lower side of the door frame where the gate is installed and coupled to the back of the gate to erect or lay down the support to erect or lay the gate, so it is advantageous to have a high gate, but if the height of the gate is increased , The stroke of the hydraulic cylinder increases, as well as the length of the support, and the increase in the stroke of the hydraulic cylinder and the length of the support consequently inevitably widen the width of the door frame, along with problems such as coastal roads or embankments of rivers. Since the road is a narrow road with a width of less than 6 meters, there is a problem in that a high gate cannot be installed using such a coastal road.

In addition, since the road forming the downtown river is narrow, and there is a limit to widening the width, when installing the door frame for embedding the overwater barrier without widening the width of the embankment road in the urban river, the height of the gate of the overwater barrier must be increased. There is a need.

In other words, the higher the height of the gate of the overpass barrier can effectively prevent overpass or flood, but the higher the height of the gate, the problem of increasing the stroke of the hydraulic cylinder, the structural problem of having to lengthen the support, and the high gate ratio When the door frame is laid down, the width of the door frame supporting it must be widened accordingly. In particular, in order to widen the door frame, civil engineering work to widen the narrow coastal road must be preceded. The height was bound to be limited.
