Soft and elastic collision protection facility for bridge pier on water transportation channel

Abstract

The invention relates to a collision protection facility, in particular to a soft and elastic collision protection facility for a bridge pier on a water transportation channel. The facility comprises a pile foundation, a bearing table and a collision protection part, wherein the upper end of the pile foundation is leveled with a river bed, and the bottom end of the pile foundation is fixed on a hard layer; the lower end of the bearing table is fixed with the pile foundation, and the upper end of the bearing table is higher than a hundred-year riverway low water level; and the collision protection part sequentially consists of a collision protection table, a pipe bolt and a tire from inside to outside, wherein the lower end of the pipe bolt is fixed on the bearing table, and the upper end of the pipe bolt is fixedly connected with the collision protection table; and the tire is sleeved on the pipe bolt. Compared with the prior art, the facility has the following advantages: as the tire is provided, when the external force effect is suffered, the collision protection effect can be effectively achieved to protect the bridge pier from being collided and damaged, and ships and people also can be protected.

Description

technical field [0001] The invention relates to an anti-collision facility, in particular to a flexible and elastic anti-collision facility for a pier arranged in a waterway. Background technique [0002] Driven by the development of the market economy, the berthing industry has grown to 400,000-ton ocean-going ships, and the berths on rivers have also grown to 100,000-ton class. The transportation of rivers, oceans, and lakes has been increasing year by year. According to relevant statistics, in 2011, the national waterway completed a freight volume of 4.2 billion tons and a cargo turnover of 7.5 trillion ton-kilometers, an increase of 12% and 10% respectively over the previous year. Busy water transportation will inevitably cause the hull to collide with the pier, causing serious damage to the pier, and some even more serious damage to the bridge, causing casualties and huge property losses, causing serious traffic congestion. According to incomplete statistics, including ...

Problems solved by technology

Busy water transportation will inevitably cause the hull to collide with the pier, causing serious damage to the pier, and some even more serious damage to the bridge, causing casualties and huge property losses, causing serious traffic congestion. According to incomplete statistics, including the Yangtze River, the Pearl River and Since 1959, there have been a total of 213 recorded boat collision accidents on the three main river systems in Heilongjiang, with a total of 22 people injured, 47 people killed, and direct economic losses of hundreds of millions of yuan.

However, the environmental damage, water and land traffic interruption and other losses caused by the ship collision accident cannot be counted.
