Abstract

The invention provides a railroad bridge evacuation platform and belongs to the technical field of railroad traffic engineering. The problem that beam sheets can not be widened easily through an existing railroad T-beam evacuation platform is solved. The railroad bridge evacuation platform comprises a cantilever beam installed at the top of a T-beam and extending outwards. A ballast stop wall is installed in the middle of the cantilever beam. Multiple front uprights are longitudinally installed at the top of the ballast stop wall. The transverse outer side of each front upright is provided with a rear upright. A beam is installed at the top of each front upright and the top of the corresponding adjacent rear upright. The top of each beam is provided with a flier. The edges of the transverse outer sides of the fliers are provided with handrails. According to the railroad bridge evacuation platform, the number of beam sheets of the T-beam can be obviously reduced, the size of piers and the size of foundations do not need to be increased, the dead load above a bridge floor is remarkably improved, and structural safety is enhanced.

Description

technical field [0001] The invention belongs to the technical field of railway traffic engineering, and relates to railway engineering. Emergency rescue stations need to be set up in long railway tunnels or tunnel groups. In order to facilitate rapid evacuation of personnel to safe areas, safe evacuation passages need to be set up on both sides of bridges near the tunnels. General railway Bridges cannot solve the problem of evacuation channels. It is a new type of solution to meet the requirements of the width of the evacuation platform by transforming the structural measures of the T-beam roof of the railway. Background technique [0002] With the development of our country's national economy, people's living standards are getting higher and higher, and the population flow and material trade between various parts of the country are also increasing. The transportation aspect also restricts the development of society. "To get rich, build roads first "The idea also fully embod...
