Description
Technical field
The present invention relates to a kind of frame bridge construction method, set up executing of frame bridge particularly to method dilatory under a kind of existing railway line
Work method.
Background technology
Under existing railway line during newly-built frame bridge, existing construction method is to use pipe jacking method.What jacking existed lacks
Point has: 1) force-transmitting pole and distribution beam are in pressured state in use, owing to the slenderness ratio of rod member is relatively big, and easy unstability,
The pressure that can bear is less, therefore can not give full play to the mechanical property of material, and the usage amount causing force-transmitting pole and distribution beam is non-
Chang great, has bad luck relatively costly by the most up to tens tons；2) haul distance of every one jack of jacking in jack-in process,
Being accomplished by the force-transmitting pole using crane constantly to change different length, the job demand of outward transport of cutting the earth in period frame bridge stops,
Speed of application is relatively slow, relatively costly；3) jack-in process center is built bridge horizontal level and elevation are not easily controlled, and often go out
The biggest deviation.
Summary of the invention
The present invention is to solve that when existing jacking sets up frame bridge, construction cost is higher, speed of application is relatively slow, and jacking
Horizontal level and elevation that journey center is built bridge are not easily controlled, problem relatively large deviation often occur, it is provided that a kind of existing railway
Under line, dilatory method sets up the construction method of frame bridge.
The present invention is to solve that above-mentioned technical problem adopts the technical scheme that: dilatory method under a kind of existing railway line of the present invention
