Elastic obstruction block of highway barrier

The invention relates to an elastic obstruction block of a highway barrier, comprising a large arc shrapnel, a small arc shrapnel, bolts, nuts and washers, wherein the large arc shrapnel is connected with an upright column, both ends of the small arc shrapnel are connected with the large arc shrapnel through the bolts, the nuts and the washers, and the middle part of the small arc shrapnel is connected with a barrier corrugated plate through the bolts. Compared with the traditional obstruction block, in the invention, materials and a structure are greatly improved, the connecting size of the obstruction block and the barrier corrugated plate is not changed, the shrapnel accords with relevant national and international standards, the use performance of the obstruction block is improved, and the running safety can be efficiently enhanced. The elastic obstruction block has the advantages of strong shock resistance, favorable deformation effect and long service life.
