Shape-adaptive pier anti-vehicle-collision device

Abstract

The invention belongs to the field of safety protection device equipment in bridge engineering construction and particularly relates to a shape-adaptive pier anti-vehicle-collision device. The shape-adaptive pier anti-vehicle-collision device comprises multiple identical flexible anti-collision units and a steel cable. A vertically through rigid shaft is arranged in the middle of each flexible anti-collision unit, the steel cable penetrates into openings in the upper end and the lower end of each rigid shaft, the flexible anti-collision units are sequentially strung through the steel cable to cover a pier, a body of the anti-vehicle-collision device is formed, and the flexible anti-collision units are independent. According to the shape-adaptive pier anti-vehicle-collision device, the technical problems that in the prior art, due to the fact that an anti-collision device needs to be produced in a highly customized mode according to the specific condition of a bridge, the production period is long, and the production cost is high are solved, the shape-adaptive pier anti-vehicle-collision device can actively adapt to various bridges in different shapes, standard production can be achieved according to different anti-collision requirements, and a series of advantages of being short in construction period, low in building and maintenance cost and the like are achieved.

Description

technical field [0001] The invention belongs to the field of safety protection devices in bridge engineering construction, and in particular relates to a shape-adaptive bridge pier anti-collision device, which can effectively reduce the impact force of a vehicle colliding with a bridge pier, reduce the loss caused by the collision, and reduce replacement costs. Background technique [0002] With the vigorous development of my country's transportation industry, there are more and more bridges such as flyover bridges. While alleviating traffic pressure, it also brings many hidden dangers of traffic accidents. For example, it is not uncommon for high-speed cars to collide with bridge piers. . Therefore, it is very meaningful and necessary to study the vehicle collision prevention device for bridge piers. [0003] At present, most of the domestic mainstream anti-collision devices are elastic deformation anti-collision facilities and crushing deformation anti-collision facilities...
