Description
Technical field
The present invention relates to bridge construction technical field, refer to that a kind of rail rail traffic bridge of embracing evacuates inspection platform particularly.
Background technology
Magnetic levitation track traffic and cross-saddle single-track traffic all adopt unique " embracing rail " method of operation, and the small bore single line case beam meeting vehicle gauge is the most economical beam type of " embracing rail " formula track traffic.Program beam structure is travelled by vehicle track, and the juxtaposed mode process of two panels single line case beam is taked in two-wire location, and domestic built magnetic is floating all adopts this beam type with straddle-seat type single traffic rail beam.Fig. 1 is Shanghai high speed Maglev rail beam sectional view, Tu2Shi Chongqing City straddle-seat type single traffic rail beam sectional view, and Fig. 3 is certain medium-and low-speed maglev traffic experiment line rail beam sectional view." embrace rail " because of vehicle to run, on small bore single line box girder bridge, space is less, limited space can be utilized, case top surface of the beam can only meet track and arrange needs, power rail, cable can be hung on outward case beam sides and bottom surface, and passage when circuit maintenance repair maintenance and vehicle generation accident needed for passenger's emergency evacuation cannot be arranged.
Shanghai high speed Maglev, domestic medium-and low-speed maglev test wire and Chongqing build Article 1 cross-saddle single-track traffic line---No. 2 line elevated bridges all do not arrange evacuation inspection platform, as Human Evacuation during Emergency difficulties such as fire, on bridge, line upkeep is also more inconvenient.For meeting circuit regular maintenance and rescue run needs, Chongqing City is when building Article 2 cross-saddle single-track traffic line-Rail Transit Line 3, complete the cable laying along circuit by erection girder steel independent between two trajectory beams, on it, grid coverage steel plate forms maintenance and rescue run passage.This processing mode solves the access issues of daily line upkeep and passenger's emergency evacuation, but still there are some defects: fire escape end face is far below vehicle floor face, and evacuating personnel is extremely inconvenient; Around fire escape, railing is not set, when the amount of evacuating an endless flow of people is large, swarm and jostlement event easily occurs; Inspection platform and rescue run passage are integrated, and the cable that inspection platform is placed breaks when passenger evacuation or electric leakage can cause personal injury to passenger.
Summary of the invention
