A high-speed anti-collision barrier with multi-directional buffering and deceleration

Abstract

The invention provides an expressway crash barrier with multidirectional buffer and deceleration, comprising vertical buffer devices, transverse buffer devices, pillar rollers, arc bar rollers, arc bars, and pillars. The vertical buffer devices are arranged evenly at the side of a highway and are fixed via concrete; vertical buffer channels are arranged in the tops of the vertical buffer devices and are slidably connected with vertical moving bars; the transverse buffer devices are fixedly connected with the tops of the vertical moving bars; transverse buffer channels are arranged in the topsof the transverse buffer devices and are slidably connected with the pillars; the arc bars are fixedly connected to the pillars; arc bar posts are fixedly connected between the arc bars; the arc bar posts are arranged evenly on the arc bars; the pillars are rotationally connected with the pillar rollers; the pillar rollers are arranged with one above the other between the arc bars. The vertical buffer devices and the transverse buffer devices counteract part of impact energy when a vehicle crashes on the barrier herein; frictional decelerating rollers inside allow the crashed vehicle to decelerate and stop as soon as possible and prevent the vehicle from rushing out of the barrier.

Description

technical field [0001] The invention relates to a high-speed guardrail, more specifically, to a multi-stage buffering high-speed crash-proof guardrail. Background technique [0002] High-speed anti-collision barrier is the main form of semi-rigid guardrail, which is a continuous structure of corrugated steel guardrail panels spliced ​​with each other and supported by the main column. It uses the deformation of the soil foundation, columns, and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction, preventing the vehicle from rushing out of the road, so as to protect the vehicle and passengers and reduce the loss caused by the accident. The corrugated beam guardrail is soft and soft, has a strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with the road alignment, and has a beautiful appearance. It can be used on small radius curves, and...
