OVERFLOWING PREVENTION DEVICE FOR BETTER VIEW OF RIVER

摘要

An overflow prevention device for improving the view of a river is provided not to pass through a complicated process such as the land compensation, to prevent the damage of a river view due to the installation of a concrete dam against floods, to prevent floods and to utilize as a handrail for preventing an accidental fall to a river at ordinary times. An overflow prevention device is formed by installing a foundation structure(10) to a river bank, installing an installation frame(20) provided with a rotation hole(21) to the upper part of the foundation structure by an anchor bolt(25), installing a buoyant body(30) provided with an insertion hole to the rotation hole by rotary projections(31) formed on two sides of the buoyant body, locating a handrail on the upper part of the buoyant body and installing the handrail on a support, forming hanging projections on two sides of the support, forming tongs on two lower sides of the support, and forming a rotary plate between the tongs, wherein the buoyant body rises up in a flood and the rotary projections of the buoyant body are coupled with the tongs of the handrail located on the upper part of the buoyant body, and the insertion hole formed on the upper part of the buoyant body is coupled with the rotary plate formed on the bottom of the support of the handrail, so that the buoyant body and the handrail rotate together. The rotary projection of the buoyant body is formed in a rectangle having an arc-shaped end, and the rotary hole of the installation frame is composed of one body by making a circular unit(22), a rectilinear unit(23) and an elliptical unit(24) in contact with one another.
