Protective pier for highway bridge and using method thereof

Abstract

The invention discloses a protective pier for a highway bridge and a using method thereof. The protective pier comprises a first fixing ring, a second fixing ring, a connecting rod, two clamping rings and an inflation mechanism, and the bottom of the first fixing ring and the top of the second fixing ring are fixedly mounted through the connecting rod. According to the protective pier for the highway bridge, when a flood disaster occurs in an urban area, water enters the storage pipe fitting and chemically reacts with the effervescent disintegrant, a large amount of carbon dioxide gas is rapidly generated and enters each compression part, and the compression air bags extend outwards after being inflated and expanded to surround the outer side of the bottom of the pier; and when an automobile or other sundries floating along with water flow in flood collides towards the pier, the automobile or other sundries can be bounced away by the inflated and expanded compressed air bag, the problem that the pier is damaged due to collision of the automobile floating along with the flood is greatly avoided, and the expanded compressed air bag can also provide a safe shelter for nearby victims. And people falling into the flood can be rescued by the expanded compressed air bag.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to a protective pier for highway bridges and a method for using the same. Background technique [0002] With the development of the city, in order to alleviate the traffic congestion in the city, it is often chosen to build a viaduct in the city, and the viaduct must be supported by piers on the ground. In order to ensure the safety of the viaduct in the city, many will choose A protective structure is provided on the outside of the bottom of the bridge pier to avoid accidental damage to the bridge pier by passing vehicles and affect the safety of viaduct traffic. [0003] In the prior art, such as Chinese Patent No.: CN 113174888 A "a protective pier for highway bridges with high crash resistance", which includes: supporting columns; The supporting columns are arranged at even intervals to form the supporting main shaft of the road bridge; the load-bearing beam frame is co...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a protective pier for highway bridges and its use method, to solve the above-mentioned background technology when there is a flood disaster in the city, vehicles or other sundries will be pushed by the fierce flood, and there will be continuous impact on the pier In some cases, the protective devices buried in the ground are not only complicated to install and labor-intensive, but also damage the road surface. After the integrity of the road surface is damaged, in the event of a flood disaster, the road surface is soaked in water for a long time, which is more likely to lead to cracking of the road surface, which in turn leads to damage to the anti-collision structure of the pier. The problem of greatly weakened impact resistance
