The present invention relates to an environmentally friendly bridge scour prevention facility, and more particularly, to fundamentally prevent damage to local bridge foundations caused by surface water currents in friction with the bridge foundations, and to plant planted aquatic plants. The present invention relates to an environment-friendly pier-based scour prevention facility that prevents scour from occurring in the water along with solid cohesion due to the rooting of the root, and provides habitat and spawning place for aquatic plants and organisms.

In general, bridges constructed in rivers are sized according to river width, surrounding environment, traffic volume, or traffic volume, and are installed in rivers, lakes, and straits. The structure is divided into substructure and superstructure.

That is, the upper structure of the bridge is composed of slabs, which are floor plates that allow vehicles, etc. to be carried on the upper part, and girder supporting them, and the lower structure has shifts and bridges that safely support the loads acting on the upper structure on the ground. Depending on the type of pile foundation, well foundation, etc. are determined and installed.

However, the constructed bridge is part of the structure, such as bridges, beams, shifts in the water and the earth and sand contacted with the structure is scoured by the flow rate upstream of the river to collapse or sink the structure to shorten the life of the bridge To cause an accident.

Therefore, local scour around the pier is one of the major causes of bridge failure.

Strong vortices always occur around the bridge piers depending on the flow direction of the stream. The reason is that when the streams meet obstacles such as bridge piers, they are deflected and the soil is easily swept away. .

Accordingly, in order to prevent scour around the pier, concrete foundation slab is placed in concrete, but scour phenomenon occurs in continuous stream water flow even if the pier foundation portion is flat terrain according to the flow direction.

The present invention is to solve the above problems, and to fundamentally prevent the damage of the local pier base caused by the surface water current friction with the pier foundation, and to solid bond due to the rooting of the planted aquatic plants and In addition, it aims to provide an environment-friendly pier-based scour prevention facility that prevents scour in the water and provides habitat and spawning places for aquatic plants and organisms.

In order to achieve the above object, the present invention is a cylindrical body having an outer cylinder portion at the bottom having a spaced apart protrusion and the fitting hole is fixed to the upper portion, the inner cylinder having an ecological movement hole to move the aquatic organisms in the lower portion An addition is formed, and a mesh body is formed in the upper portion of the ecological movement hole inside the outer cylinder part to couple the inner cylinder part and the inner cylinder part to be mixed and filled with crushed stone or soil on the upper part, and wrapped around the piers at the outer periphery;

A plurality of bolts formed to protrude outward and up and down, respectively, fixed to each side of the lower end of the pier pillar, and having an upper portion wound around the pier pillar by a binding band;

One end is bolted to the bolt part of the fixture, and the other end sequentially penetrates through the fitting holes of the outer cylinder of the multiple buckling prevention tool, and penetrates to the top of the lower fitting hole to be fixed to the pillar pillar. The support portion is formed, and the lower end of the support portion is bent upward, the fastening guide is formed with a planting frame moving portion having a guide groove in the center and the movement field groove on both sides;

It is an arrow-shaped box having a projecting portion with a protruding portion protruding to the outside, and aquatic plants are planted in the inner side, the root body protrudes in the lower portion, and a roller shaft fitted into the guide groove is protruded and bent in the inner side. Both sides of the shaft is characterized by having a buoyancy type frame which is a buoyancy material sliding triangular roller coupled inside the moving field groove.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
