Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a damping bridge device for rail transit tunnel top passing through a rail.
Background
According to the specification of 15.4.11 in the subway design Specification GB50517-2013, when the cable passes through the track, the cable can be laid by passing a hard non-metal pipe under the track or by laying along the top of the tunnel in a rigid fixing mode. At present, if a cable is laid by adopting a track downward-penetrating mode, due to the severe environment of a track traffic underground construction site, long construction period and various cross operations, pipes reserved in downward-penetrating tracks are always left almost due to the reasons of breakage, concrete blockage, artificial damage and the like. If the scheme of crossing the tracks at the top is adopted, namely the common mode of rigidly fixing the anchor bolts and the bridge frame at the top of the tunnel structure is adopted. When the train moves, the train vibrations arouse tunnel structure vibrations, and tunnel piston wind transversely strikes top crane span structure, and these all can great influence top crab-bolt's fixed reliability, along with operation time's the process, the not hard up risk of rigid fixation crab-bolt increases gradually, under the effect of gravity, if the crane span structure in case falls, will produce great influence to the normal operation of circuit.
At present, no better solution is available for the overhead rail-passing bridge of the rail traffic tunnel at home and abroad.
