Deformable protective fence for highway construction
The invention relates to the technical field of protective fences, in particular to a deformable protective fence for highway construction, which comprises a rectangular frame, a connecting mechanism is arranged on the side wall of the rectangular frame, and a plurality of through holes are formed in the top of the rectangular frame at equal intervals. A plurality of protective shells corresponding to the through holes are rotationally connected between the upper inner wall and the lower inner wall of the rectangular frame at equal intervals, air bags are fixedly connected to the surfaces of the protective shells, and first vent holes are formed in the lower portions of the surfaces of the protective shells; a plurality of second vent holes communicated with the air bag are formed in the surface of the protective shell in a circumferential array manner; the protective shell is arranged, on one hand, after a vehicle running at a high speed collides with the surface of the protective shell, the vehicle is rebounded and drained to the road along with the rotating force of the protective shell, the running direction is adjusted, on the other hand, the inflated air bag is beneficial to reducing the collision force between the vehicle and the protective shell, and therefore the collision resistance of the protective shell is improved.
本发明涉及防护栏技术领域，尤其是一种公路施工用可变形防护栏，包括矩形框，所述矩形框的侧壁上设有连接机构，所述矩形框的顶部等距开设有多个贯穿孔，所述矩形框的上下内壁之间等距转动连接有多个与所述贯穿孔相对应的防护壳，所述防护壳的表面上固定连接有气囊，所述防护壳的表面下方开设有第一通气孔，所述防护壳的表面呈圆周阵列开设有若干个与所述气囊相连通的第二通气孔；设置的防护壳，一方面高速行驶的车辆撞击到防护壳的表面后，会随着防护壳的转动力将车辆回弹引流至道路上，摆正行驶方向，另一方面被膨胀起来的气囊有利于减缓车辆与防护壳之间的撞击力，从而提高防护壳的受撞性。
