Abstract

The invention discloses an urban railway traffic engineering emergency escape pipeline structure and a design method, and relates to the technical field of railway traffic engineering. The structure comprises multiple steel pipes, first hoisting rings, second hoisting rings, connecting steel plates, connecting holes and U-shaped bolts; the multiple steel pipes are arranged side by side, the first hoisting rings and the second hoisting rings are arranged on the side wall of the steel pipes, the connecting steel plates are welded to the two ends of each steel pipe; the three connecting steel plates are uniformly arranged on the same cross section of the steel pipes along the circumference, and the connecting holes are formed in the connecting steel plates; the two adjacent steel pipes are connected by inserting the bolts into the connecting holes. According to the urban railway traffic engineering emergency escape pipeline structure and the design method, when collapse occurs in subway construction and accidents such as fire break out during operation, an isolated evacuation pipeline can be provided, constructors and passengers at stations and trains can evacuate rapidly, and certain escape requirements are met; the structure has the advantages of being simple in structure, easy to operate, safe, reliable, reasonable to arrange and the like.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an emergency escape pipeline structure and design method for urban rail transit engineering. Background technique [0002] Rail transit is playing an increasingly important role in urban public transportation. Urban rail transit has become the best solution to urban congestion due to its energy-saving, land-saving, large-capacity, all-weather, less-pollution and safety features. The history of transportation development in cities in economically developed countries tells us that only the urban rail transit (subway and light rail) system with large passenger capacity is the effective way to fundamentally improve the urban public transportation situation. [0003] The construction and development of urban rail transit is conducive to improving the efficiency of citizens' travel, saving time and improving the quality of life. In internationally renowned metropolises, due to th...
