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
The present invention relates to a kind of steel structure hangar tunnel and mounting method, belong to the hangar tunnel technical field.
Background technology
In the tunnel and the special cutting place of existing rail track, because the variation of landform, landforms, there are disasters such as landslide, landslide, falling rocks to take place during massif and seriously jeopardize traffic safety.Traditional approach is to build permanent hangar tunnel (reinforced concrete structure), and shortcoming is a cost height, long in time limit, needs 120 days usually, and construction is disturbed big to transportation, more can not adapt to sudden specific demand of speedily carrying out rescue work.And, the problem that line standard is low, disease is many is arranged for the railway in mountain area, along with transportation development all will progressively be transformed, building hangar tunnel is interim measure, therefore builds permanent hangar tunnel and more there is no need.
Summary of the invention
The objective of the invention is to: provide a kind of suitable road to speedily carry out rescue work and transform the steel structure hangar tunnel and the mounting method of preceding interim measure with existing line, to overcome the deficiencies in the prior art.
The present invention constitutes like this: steel structure hangar tunnel, structure comprises base, is provided with column on base, is provided with longeron on column, is provided with crossbeam on longeron, lays plank and backfill on crossbeam.
Above-mentioned steel structure hangar tunnel is provided with pull bar between column.
Above-mentioned steel structure hangar tunnel, column is formed by connecting by bolt by the steel buttress.
Above-mentioned steel structure hangar tunnel, the structure of steel buttress comprise iron plate and following iron plate, 4 angle steel of welding between last iron plate and following iron plate, and the band steel of usefulness is strengthened in welding between 4 angle steel.
Above-mentioned steel structure hangar tunnel is provided with insulating slab below crossbeam.
The steel structure hangar tunnel mounting method, in factory, make each parts of steel structure hangar tunnel earlier, build the floor manufacture base of position at hangar tunnel, the steel buttress of making is installed on the base,, the steel buttress is connected by bolt according to design height, be assembled into column, fixing longeron on column is installed crossbeam again on longeron, lay plank and backfill at last on crossbeam.
Above-mentioned steel structure hangar tunnel mounting method, each parts of described steel structure hangar tunnel comprise steel buttress, pull bar, longeron and crossbeam.
Above-mentioned steel structure hangar tunnel mounting method, backfill adopt the earth bag husky and soil of packing into to fold sign indicating number.
The present invention is designed to the steel work pattern according to the requirement of existing railway line to hangar tunnel rigidity, intensity, gauge.Take all factors into consideration structural strength, the transportation characteristics are divided into several portions, parts, and all these steelwork components adopt batch production production, have interchangeability, versatility.On-the-spot need or in case dangerous situation takes place, be transported to the scene after, can carry out composite assembly (building block system), be characterized in that handling demolition is convenient, light and handy flexibly, construction speed is fast, interference on the road is little, after dangerous situation was eliminated, dismountable turnover was used.Adopt method of the present invention, only needed just hangar tunnel can be installed in 3～5 days, shortened the engineering time greatly, especially be fit to the interim measure before railway emergency rescue and existing line are transformed.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to view;
Accompanying drawing 3 is the structural representation of steel buttress of the present invention.
The specific embodiment
Embodiments of the invention: in factory, make parts such as steel buttress 6, pull bar 5, longeron 3 and crossbeam 4 earlier, build the floor manufacture base 1 of position at hangar tunnel, steel buttress 6 is installed on the base 1, according to design height, steel buttress 6 is connected by bolt, be assembled into column 2, fixing longeron 3 on column 2 tops, crossbeam 4 is installed on longeron 3 again, on crossbeam 4, is laid plank 9 and backfill 8 at last, can obtain hangar tunnel.Cylinder lever connecting rod 5 between column 2, guarantee the Stability Analysis of Structures of hangar tunnel.Fitting insulating panels 7 can also be installed bearing diagonal 14 to guarantee safety between column 2 and crossbeam 4 below crossbeam 4, improves stability.
The structure of steel buttress 6 comprises iron plate 12 and following iron plate 13,4 angle steel 10 of welding between last iron plate 12 and following iron plate 13, and the band steel 11 of usefulness is strengthened in welding between 4 angle steel 10, produces screw on last iron plate 12 and the following iron plate 13.
Longeron 3 and crossbeam 4 adopt alloy-steel plate weldering system, and longeron 3 is fixed on the column 2 by high-strength bolt, and crossbeam 4 is tiled on the longeron 3 with constant spacing.Plank 9 is made into same specification in factory, then at plank 9 bottom surface installing and locating angle steel, on-the-spot plank 9 is fixed gets final product on crossbeam 4.Backfill 8 adopts the earth bag husky and soil of packing into to fold sign indicating number, and easy to operate, speed is fast.
The senior rustproof paint of all steel part sparies two roads, the special-purpose finish paint of steel bridge two roads are with anti-corrosion.
