Anti-collision expressway guardrail
The invention discloses an anti-collision expressway guardrail which comprises stand columns, the stand columns are fixedly connected with breast boards through connecting pieces, the breast boards comprise the front breast board and the rear breast board, each connecting piece comprises a connecting cylinder and a connecting circular ring, one end of each connecting cylinder is fixedly connectedwith the corresponding stand column, The outer circumferential surface of the other end of the connecting cylinder is provided with an annular protrusion, the inner circumferential surface of one endof the connecting ring is provided with an annular baffle, the inner side face of the annular baffle is attached to the side face, close to the stand column, of the annular protrusion, and the other end of the connecting ring is provided with a connecting plate; the two connecting plates are fixedly connected with the middle positions of the two arc-shaped parts of the rear breast board respectively, and the parts, located between the stand columns and the annular baffle, of the connecting cylinders are sleeved with compression springs. The expressway guardrail solves the technical problem that the energy absorption capacity of an existing expressway guardrail is limited when collision occurs.
本发明公开了一种防碰撞高速公路护栏，包括立柱，立柱通过连接件固定连接有栏板，栏板包括前栏板和后栏板，连接件的数量为两个，连接件包括连接圆柱和连接圆环，连接圆柱的一端与立柱固定连接，连接圆柱另一端的外圆周面设有圆环形凸起，连接圆环一端的内圆周面设有圆环形挡板，圆环形挡板的内侧面与圆环形凸起靠近立柱的侧面贴合，连接圆环的另一端设有连接板，连接圆环的空腔内填充有缓冲物，两个连接板分别与后栏板两个弧形部分的中间位置固定连接，连接圆柱位于立柱和圆环形挡板之间的部分外套有压簧。本发明解决了现有的高速公路护栏在发生碰撞时吸收能量的能力有限的技术问题。
