Bridge pier anti-collision wall in expressway medial strip
The invention discloses a bridge pier anti-collision wall in an expressway medial strip, which comprises a heightened protection section and a transition section, the heightened protection section wraps at least one pier in the middle, a gap is reserved between the heightened protection section and the pier, a transition section is arranged between the heightened protection section and an expressway central guardrail, the transition section is of a height transition structure, the height of the heightened protection section is gradually transited to the height of the guardrail, the head-on collision face of the heightened protection section and the head-on collision face of the transition section are of slope face structures with the same slope face angle, and the heightened protection section is a reinforced slope face section. The impact force of vehicles on the piers can be dissipated, heeling generated when the vehicles collide with the piers is reduced, and the protection level of the piers arranged on the highway medial strip is improved.
本发明公开了一种高速公路中央分隔带内桥墩防撞墙，包括加高防护段和过渡段，所述加高防护段将至少一个桥墩包裹在中间，并与所述桥墩之间留有空隙，所述加高防护段与高速公路中央护栏之间设置所述的过渡段，所述过渡段为高度过渡结构，从所述加高防护段的高度逐渐过渡至所述护栏的高度，所述加高防护段和所述过渡段的迎撞面为坡面角度相同的坡面结构，且所述加高防护段为加强型坡面段。本发明可耗散车辆对桥墩的撞击力，减少车辆撞击桥墩产生的侧倾，提高对高速公路中央分隔带布设桥墩的防护等级。
