Concrete anti-collision guardrail
The concrete anti-collision guardrail comprises a fixed outer concrete retaining wall extending in the length direction of a road, and a plurality of fixed inner concrete check blocks are arranged on the inner surface of the outer concrete retaining wall; an inner concrete sliding block is arranged on the front side of each inner concrete check block, a lower inclined face is arranged on the front side of each inner concrete check block, an upper inclined face is arranged on the rear side of each inner concrete sliding block, and the upper inclined face of each inner concrete sliding block abuts against the lower inclined face of the adjacent inner concrete check block on the rear side. A connecting beam is fixed to the multiple inner concrete check blocks together, a first screw is embedded in each inner concrete sliding block, long through holes corresponding to all the first screws one to one are formed in the connecting beam in a penetrating mode, and the upper section of each first screw extends out of the top face of the corresponding inner concrete sliding block and penetrates through the corresponding long through hole in the connecting beam. A limiting nut used for clamping an upper opening of the long through hole is screwed on the rod section, extending out of the long through hole, of each first screw rod. The concrete anti-collision guardrail is good in buffering and energy dissipation effect on a vehicle during scraping and collision, and damage to the vehicle and threat to people in the vehicle can be effectively reduced.
本发明公开一种混凝土防撞护栏，它包括沿道路长度向延伸的固定式的外砼挡墙，外砼挡墙内表面设有多个固定式的内砼挡块；每个内砼挡块的前侧设有一个内砼滑块，每个内砼挡块前侧设有下斜面，每个内砼滑块后侧设有上斜面，每个内砼滑块的上斜面抵靠在后侧相邻的内砼挡块的下斜面上；多个内砼挡块共同固定有一根连接梁，每个内砼滑块预埋有第一螺杆，连接梁贯通有与全部第一螺杆一一对应的长通孔，每根第一螺杆上段伸出内砼滑块顶面并穿过连接梁上对应长通孔，且每根第一螺杆伸出长通孔的杆段旋有用于卡住长通孔上口的限位螺帽。该混凝土防撞护栏刮擦碰撞时对车辆的缓冲耗能效果好，能有效降低对车辆的破坏和对车内人员的威胁。
