Abstract
The utility model relates to the technical field of railway buildings, in particular to a snow fence for railways. The snow fence is an effective way of protecting the railways from wind blowing and snow disasters. Existing snow fences at home and abroad are various in types. Most of the existing snow fences adopt wood structures and belong to light structures, thereby being convenient to move. Service life is kept between 3 years and 5 years. a small part of the existing snow fences adopt concrete structures, accordingly service life can reach 3 years to 60 years, but the structure is heavy and cannot be moved. The snow fence is provided with concrete fixing columns, and cellular protection nets and punched galvanized steel plates are arranged between the cellular protection nets and fixed through effective connection parts. The snow fence is made of light materials, thereby being flexible in construction, short in period, stable in structure and easy to dismount. The snow fence is arranged at two ends of railways, thereby being capable of effectively preventing wind and snow, preventing the railways from being buried by snow blown by wind and guaranteeing safety of railway train operation in hazardous areas.
Description
Technical field
The utility model railway construction technical field is specifically related to a kind of railway snow hurdle.
Background technology
Smart she Huo Tielu is positioned at Xinjiang Uygur Autonomous Regions western Mongolian Autonomous Prefecture of Bortala and Kazak Autonomous Prefecture of Ili; Total length 286km is the electric railway that China's article one is carried out the snow injury control comprehensively, and circuit is through the about 60km in snow injury area; This district's accumulated snow is deep; The 30 years one maximum accumulated snow 221cm of chance, snowslide along the line, wind snow endanger bigger, serious harm railway operation safety.Circuit passes through snow injury area 26.701km with the roadbed form; Snowslide area 0.875km wherein, wind snowfield district 25.826km, especially cutting location; The accident that wind snow is buried railway takes place more easily; Be not only smart her Huo Tielu, comparatively frequent area takes place in snow injury in all, all presses for suitable snow injury prevention and cure project and ensures railway operation safety.Resistance snow fence hurdle is to avoid railway to suffer comparatively one of effective method of wind snow disaster evil, and domestic extrernal resistance snow fence hurdle pattern is more, adopts wooden structures more basically, belongs to light structures, be convenient to move, but the life-span maintains 3 to 5 years basically; Few part adopts concrete structure, though the life-span can reach 30 ~ 60 years, structure is heavy, can not move.
Summary of the invention
The purpose of the utility model provides a kind ofly can play anti-wind and snow effect, prevent a kind of railway snow hurdle that rail is buried by wind snow.
The technical scheme that the utility model adopted is:
A kind of railway snow hurdle includes vertical columns, it is characterized in that:
Two fence wire rope up and down are set between the described vertical columns, are fixed tightly on the vertical columns through U type kayser;
Be provided with cellular protective screening between two fence wire rope about described, cellular protective screening fixes through connecting line and fence wire rope, and cellular protective screening fixes through pressing from both sides gauze pad sheet and bolt and vertical columns;
Be fixed with the punching galvanized steel plain sheet of horizontal stripe shape on the described cellular protective screening.
The vertical columns that is positioned at the fence end is fixed on the earth anchor through tractive anchoring wire rope.
The utlity model has following advantage:
Light material is selected on the utility model resistance snow fence hurdle for use, construction flexibly and the cycle shorter, structure is firm, dismounting is provided with at the railway two ends easily, can play effectively anti-wind and snow effect, prevents that railway from being buried by wind snow, ensures the railway operation safety in the multiple district of snow injury.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1-tractive anchoring wire rope, 2-fence wire rope, 3-folder gauze pad sheet, the cellular protective screening of 4-, the 5-galvanized steel plain sheet that punches, 6-earth anchor, 7-ground, 8-vertical columns, 9-U type kayser.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
The described a kind of railway snow hurdle of the utility model is provided with into the vertical columns 8 of row; Adopt C25 reinforced concrete prefabricated, ground upper section size 20 * 20cm, underground sectional dimension 30 * 30cm; Ground upper height 3.0m; The following 0.25m of underground buried depth to the depth of frost penetration, and be not less than 1.0m, following 15cm place, 15cm place and column top reserves φ 16mm and wears the steel cable hole on the ground.Two fence wire rope 2 up and down are set between the vertical columns 8, adopt φ 13 galvanized steel wire ropes, be fixed tightly on the vertical columns 8 through U type kayser 9 after passing the steel cable hole.Be provided with cellular protective screening 4 between two fence wire rope 2 up and down, cellular protective screening 4 fixes through connecting line and fence wire rope 2, and cellular protective screening 4 fixes through pressing from both sides gauze pad sheet 3 and bolt and vertical columns 8.Cellular protective screening 4 adopts TRW III (P) type, and width 2.7m, material are that zinc-coated wire outsourcing covered plastics layer is made; Technical indicator: mesh 135 * 90mm, line footpath φ 3.6mm, single intensity is greater than 450MPa; Every square metre of intensity is greater than 25kN, elongation per unit length 10～20%, and covered plastics layer intensity is extended greater than 200%; Net base material zinc content is 250g/m, and application life is more than 50 years.Be fixed with the punching galvanized steel plain sheet 5 of horizontal stripe shape on the cellular protective screening 4, punching galvanized steel plain sheet 5 is selected the low-carbon (LC) galvanized steel plain sheet for use, thickness 0.5mm, and length 280cm, width 18cm, punching galvanized steel plain sheet 5 intensity, hardness are carried out the requirement of 235# steel GB.
The vertical columns 8 that is positioned at the fence end is fixed on the earth anchor 6 through tractive anchoring wire rope 1.Earth anchor 6 sizes 20 * 20 * 30cm adopts the C15 concrete for making, is embedded in underground and is not less than 1.0m.
