Abstract

The invention relates to the technical field of a safety protection device in the bridge engineering construction, in particular to an efficient low-cost flexible energy dissipation type pier anti-collision safety device. The invention aims at solving the problems that the safety of an automobile, pedestrians and a pier is difficult to be ensured when the automobile is rigidly collided with the pier in the prior art. The invention adopts a technical proposal at present: the efficient low-cost flexible energy dissipation type pier anti-collision safety device comprises a steel anti-collision wall which is formed by the sheathing of a big protection cylinder and a small protection cylinder; the inner part of the anti-collision wall is a hollow structure and filled with elastic energy dissipation materials; a horizontally-distributed spring component layer is arranged between the protection cylinder and the small protection cylinder; the bottom is arranged on a base steel plate, the external extension part of which is provided with an anchor in a perforating way; and the upper end and the lower end of the inner side of the small protection cylinder are respectively provided with an energy dissipation piece horizontally. The invention has the advantages of: 1) high safety and good effect; 2) simple structure, easy construction and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of safety protection devices in bridge engineering construction, in particular to a high-efficiency and low-cost flexible energy dissipation type bridge pier anti-vehicle collision safety device. Background technique [0002] At present, the current situation of road traffic safety in our country is worrisome. Due to the increase in traffic volume, the contradiction between cars and bridges (especially overpass bridges) has become more and more prominent. Accidents of cars hitting bridge piers often occur, and in severe cases, bridge piers will collapse. The car crash caused irreparable loss of life and property. The reason is that the direct impact of the car on the bridge pier is a rigid impact, and this process lacks energy dissipation, so the damage is extremely great. [0003] In order to solve this problem, some anti-collision measures have been taken in the existing design, such as increasing the str...
