Steel structure hangar tunnel and installation method

Abstract

The invention discloses a steel structure hangar tunnel and an installation method. The steel structure hangar tunnel comprises a base (1), wherein an upright post (2) is arranged on the base (1), a longitudinal beam (3) is arranged on the upright post (2), a crossbeam (4) is arranged on the longitudinal beam (3), and a wood board (9) and backfill soil (8) are laid on the crossbeam (4). The invention is designed into a steel structure mode according to the requirements of rigidity, strength and delimitation of a hangar tunnel by the traditional railroad line. The steel structure hangar tunnel is divided into a plurality of parts and assemblies by synthetically considering the characteristics of structural strength and transportation, and all the steel structure assemblies adopt factory production and have interchange ability and universality. The steel structure hangar tunnel is convenient to assemble and disassemble, is light and flexible, has quick construction progress and low interference with running vehicles and can be disassembled for recycling after dangerous cases are eliminated. Due to the adoption of the installation method, the hangar tunnel can be completely installed for 3-5 days in order to greatly reduce construction time.

Description

technical field [0001] The invention relates to a steel structure shed cave and an installation method, belonging to the technical field of shed caves. Background technique [0002] In tunnels and special road cuttings of existing railway lines, due to changes in terrain and landforms, landslides, landslides, rockfalls and other disasters occur from time to time, which seriously endanger driving safety. The traditional way is to build a permanent shed (reinforced concrete structure). The disadvantages are high cost and long construction period, which usually takes 120 days. The construction interferes a lot with transportation, and it cannot meet the special needs of emergency rescue. Moreover, for railways in mountainous areas, there are problems of low line standards and many diseases. With the development of transportation, they must be gradually transformed. Building sheds is only a transitional measure, so it is not necessary to build permanent sheds. Contents of the ...

AI Technical Summary

Problems solved by technology

The traditional way is to build a permanent shed (reinforced concrete structure). The disadvantage is that the cost is high and the construction period is long. It usually takes 120 days. The construction interferes a lot with the transportation, and it cannot meet the special needs of sudden emergency rescue.

Moreover, for railways in mountainous areas, there are problems of low line standards and many diseases. With the development of transportation, they must be gradually transformed. Building sheds is only a transitional measure, so it is not necessary to build permanent sheds.
