Pier rolling stone impact prevention device and method for monitoring rolling stone impact

Abstract

The invention discloses a pier rolling stone impact prevention device. The pier rolling stone impact prevention device comprises a pile casing arranged outside a bridge pier, an energy reduction cushion layer is arranged between the pile casing and the bridge pier, a plurality of sets of buffer devices are arranged around the bridge pier, each buffer device comprises a blocking piece, each blocking piece is connected with the pile casing through a plurality of springs, and every two adjacent blocking pieces in each set of buffer devices are connected through a flexible piece. Damage to the pier caused by collision of the rolling stones can be reduced, and safety and use performance of the pier are protected.

Description

technical field [0001] The invention relates to a bridge pier anti-rolling stone impact device and a method for monitoring the impact of rolling stones. Background technique [0002] With the continuous expansion of my country's infrastructure construction and the continuous implementation of the western development strategy, the number of bridge construction in my country has continued to increase. According to incomplete statistics, the total number of road bridges in active service in my country is nearly 1 million, of which the total number of railway bridges is 300,000, and China has become a bridge country. A bridge is a structure that can cross complex terrain such as mountains and valleys, and is often affected by adverse geological disasters. Especially bridges in mountainous areas are more likely to be impacted by boulders rolling down the side slope at the bridge site. In recent years, there have been many accidents of rolling stones hitting bridge piers in our c...

Problems solved by technology

Under the influence of wind, rain, temperature, environmental corrosion and other factors, the materials of the anti-collision facilities age rapidly, and their anti-collision performance decreases. , The energy-absorbing support structure is set in the middle, and the protective structure is set in the inner layer. The energy-absorbing system set in the middle can be composed of various energy-dissipating structures or materials, but when the anti-collision facility and the pier are not an integral structure, it occupies a large area , the construction process is cumbersome and the construction cost is high, so it is not suitable to set up the facility in mountainous areas

Therefore, the anti-collision function of the existing bridge pier anti-collision devices still needs to be improved, and a kind of efficient and intelligent bridge pier anti-collision devices and methods are urgently needed
