Impact Absorbing System of Bridge Pier

摘要

A shock absorbing system of a bridge pier of the present invention comprises a first support bar portion composed of a plurality of support rods fixed to the ground on the outside of a pier at a lower portion of a pillar of a pillar type, A plurality of first support plate portions formed at one side of the cylindrical wall portion at which vehicles often collide with each other, and a plurality of first support plate portions secured to the plurality of first support plate portions at regular intervals in a radial direction, And a plurality of inner second supporting plate portions attached to the ends of the shock absorbers of each of the square beams forming the first shock absorbing portion, A first curved corrugated plate portion which is integrally fastened to the plurality of inner second supporting plate portions, A plurality of outer second support plate portions which are fastened at positions corresponding to the second support plate portions on the outside of the first curved connecting plate portion, A second shock absorber having a plurality of quadrangular beam-like shock absorbers which are fastened to the second support plate and have a plurality of holes in a rectangular box-like body, and a second shock absorber having a quadrangular beam-A second curved corrugated plate portion formed in a curved shape to be fixed to the plurality of inner third support plate portions, and a second curved corrugated plate portion fixed to the second curved corrugated plate portion at a predetermined interval And an outer third portion which is fastened to a position corresponding to the inner third supporting plate portion outside the second curved connecting plate portion, It is characterized in that the plate-part, said outer third supporting plate a plurality of first air-bag impact absorbing air bag shape to be attached to. The first airbag impact absorbing unit may further include a fourth support bar portion formed of a plurality of ground roofs fixed to the ground at a predetermined interval at both ends or one end of the first airbag impact absorbing portion and a curved third curvilinear plate And a second air bag shock absorber attached to the outside of the third curved corrugated plate portion.;
