Solving the technical scheme that technical problem of the present utility model adopts is: be provided with down vang below being loaded on the girder steel of abutment, whole bridge floor symmetrical laying has the cable wire of extension to the two sides earth anchor, cable wire adopts the slippage of located lateral to be connected with the bridge girder steel, each bridge floor cable wire is provided with strainer, static deck transverse slope≤2 °, maximum sag≤cable way bridge clear span/40 (m) of static bridge floor span centre.
The bridge floor cable wire adopts the wire rope of Φ 45mm～Φ 52mm, cable wire adopts nut and the bridge plate of band groove and the girder steel location of bridge of band U-shaped hook, the arrangement pitch of roadway bridge floor cable wire is 140mm～350mm, sidewalk bridge floor cable wire arrangement pitch is 250～400mm, the sidewalk outside also be extended with one section girder steel and above be connected with anti-dangerous rope and steadying line in turn, steadying line and anti-dangerous rope arrangement pitch 50～100mm.
The girder steel of sidewalk and roadway position all adopts connecting bolt and the horizontal bridge plate of the band groove laid is above fixed, on the horizontal bridge plate of roadway, be equipped with vertical bridge plate, vertically anti-skidding checkered steel plate is laid on the bridge plate surface, passes checkered steel plate with bolt again and is connected on the horizontal bridge plate with vertical bridge plate.
All be provided with column edge material at the edge of sidewalk and roadway, cable wire, horizontal bridge plate and edge material linked together with the bolt of being with the U-shaped hook; Also be provided with the angle steel that is covered with vertical bridge plate on the checkered steel plate at roadway edge, link together with U-shaped hook nut and horizontal bridge plate and cable wire.
This two-way traffic cable way bridge is made of Foundation Design, bridge superstructure, bridge ancillary works.Bridge floor mainly forms flexible bridge floor by wire rope, crossbeam, Wood member and bridge floor steel plate structure.Flexible bridge floor mainly by being anchored in the main rope carrying of rock mass or gravity anchor, guarantees the bridge floor lateral stability by crossbeam and wire rope.
Foundation Design: Foundation Design mainly is made up of earth anchor, abutment and platform cap.Earth anchor is divided into gravity earth anchor and anchor cable formula earth anchor.
Bridge superstructure: form by roadway, sidewalk and bridge floor People's Bank of China guardrail.
The bridge floor railing is made up of railing post, wire rope and railing net.
The bridge ancillary works contains two sides end of the bridge janitor's room and end of the bridge lighting system.
The beneficial effects of the utility model:
(1) two-way traffic bridge deck structure has improved the supporting capacity and the traffic capacity of bridge floor, and it is current to satisfy big vehicle flowrate and heavy-duty vehicle.
(2) compare with bicycle road cable way bridge, bridge deck structure stability better; Compared with traditional permanent bridge, its cost is relatively low, and the bridge floor material can be realized recycling, and its manufacturing cost is about identical 2/3 of two the bicycle road cable way bridges in footpath of striding.
This large span two-way traffic cable way bridge applies to during water power builds in earlier stage, its carrying load can reach vapour-40T, can realize the vehicle two way, construction period only is 5 months, demonstrated fully the advantage that the two-way traffic cable way bridge duration is short, practical, cost is low, and striden river mediation engineering for construction of hydropower facilities and brought into play effect efficiently.
