Abstract
The present invention is specially a kind of railway jacked frame bridge bridge tie and changes construction method, in the presence of influence transport, labour intensity is big, operating efficiency is low and relatively costly when solving the problems, such as that existing bridge tie is changed.Before a, Framed underpass bridge, by railway ballast bottom Zha Pu to bridge floor, after the position that paves, thickness meet frame bridge condition in place, ram and clap closely knit；B, on the tiny fragments of stone, coal, etc. of bridge floor bottom by bridge tie by design requirement arranged for interval to specified location；After c, Framed underpass bridge are in place, a bridge tie is changed every six roots of sensation steel sleeper, often to change and go up railway ballast immediately after a bridge tie and make firm by ramming closely knit, after bridge tie stress is fully transmitted to bridge floor, then change next bridge tie；After the completion of d, the bridge tie of whole station track are all changed, after track stress is transformed into bridge tie and bridge floor completely, D beam girders are removed.The present invention need not block railway, and the influence to railway operation is minimized, and operation simplifies, easy to operate, improve efficiency of construction, while having prevented the phenomenon of easy generation potential safety hazard.
Description
Technical field
The present invention relates to railway D type roof beam structure unoccupied orbital construction methods, specially a kind of railway jacked frame bridge bridge tie is changed
Construction method.
Background technology
Because existing railway operation has not interruptibility, when frame-type bridges and culverts is built in Existing Railway Line increasing, jacking is commonly used
Construction, i.e., in existing railway side prefabricated frame posture bridges and culverts, after bridge main body intensity reaches the 100% of design strength, to railroad track
Reinforced, railway sleeper is removed simultaneously during reinforcing, shoveling jacking is started after reinforcing, finally reached frame bridge in place by design.
After frame bridge is in place, removes track and reinforce, recover track circuit, while changing special bridge tie.
Traditional bridge tie changes construction method：Block railway 3 hours-take-off part -- dig railway ballast-take out steel sleeper-wear bridge
Pillow-connection fastener -- backfill railway ballast-make railway ballast firm by ramming is closely knit.There is following weak point in the method：1st, block railway is needed to apply
Work, it is larger on railways train operation transport influence；2nd, need to excavate railway ballast and backfill again, workload is big；3rd, block construction is general at night,
Illumination is needed, construction inconvenience, work efficiency is low, high cost.
The content of the invention
The present invention in order to solve to exist when existing bridge tie is changed influence transport, labour intensity is big, operating efficiency is low and into
This problem higher, there is provided a kind of railway jacked frame bridge bridge tie changes construction method.
The present invention adopts the following technical scheme that realization：A kind of railway jacked frame bridge bridge tie replacing construction method, a,
Before Framed underpass bridge, by railway ballast bottom Zha Pu to bridge floor, after the position that paves, thickness meet frame bridge condition in place, ram and clap closely knit；b、
By bridge tie by design requirement arranged for interval to specified location on the tiny fragments of stone, coal, etc. of bridge floor bottom；After c, Framed underpass bridge are in place, every six roots of sensation steel
Pillow change a bridge tie, often change a bridge tie after go up immediately railway ballast make firm by ramming it is closely knit, until bridge tie stress is fully transmitted to bridge floor
Afterwards, then next bridge tie is changed；After the completion of d, the bridge tie of whole station track are all changed, track stress is transformed into bridge tie and bridge floor completely
Afterwards, D beam girders are removed.
Traditional substitute mode is overturned using the processing step, it is not necessary to block railway, and operation simple and fast, overcome
Existing bridge tie has that influence is transported, labour intensity is big, operating efficiency is low and relatively costly when changing.
Construction method of the present invention is rationally reliable, it is not necessary to block railway, the influence to railway operation is minimized,
It is easy to operate and operation is greatly simplified, efficiency of construction is improve, while prevented night work easily pacifying
The phenomenon of full hidden danger, construction cost is relatively low.
Specific embodiment
A kind of railway jacked frame bridge bridge tie changes construction method, before a, Framed underpass bridge, by railway ballast bottom Zha Pu to bridge
Face, after the position that paves, thickness meet frame bridge condition in place, rams and claps closely knit；B, on the tiny fragments of stone, coal, etc. of bridge floor bottom by bridge tie press design requirement
Arranged for interval is to specified location；After c, Framed underpass bridge are in place, a bridge tie is changed every six roots of sensation steel sleeper, often change a bridge tie
Go up railway ballast immediately afterwards and make firm by ramming closely knit, after bridge tie stress is fully transmitted to bridge floor, then change next bridge tie；D, whole station track
After the completion of bridge tie is all changed, after track stress is transformed into bridge tie and bridge floor completely, D beam girders are removed.
Claims (1)
1. a kind of railway jacked frame bridge bridge tie changes construction method, it is characterised in that：Using following steps：A, Framed underpass bridge
Before, by railway ballast bottom Zha Pu to bridge floor, after the position that paves, thickness meet frame bridge condition in place, ram and clap closely knit；B, in the bridge floor bottom tiny fragments of stone, coal, etc.
On by bridge tie by design requirement arranged for interval to specified location；After c, Framed underpass bridge are in place, one is changed every six roots of sensation steel sleeper
Bridge tie, often to change and go up railway ballast immediately after a bridge tie and make firm by ramming closely knit, after bridge tie stress is fully transmitted to bridge floor, then changes down
A piece bridge tie；After the completion of d, the bridge tie of whole station track are all changed, after track stress is transformed into bridge tie and bridge floor completely, D beams are removed
Girder.
