Abstract
A kind of construction method of the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation.It includes measuring the discrepancy in elevation between two lines road adjacent in the existing line above frame bridge to be placed；Crossbeam in unwrapping wire road reinforcement system is worn in the lower section of every circuit；Veneer in the lower end colligation of pipe nipple I-steel；Utilize the discrepancy in elevation between adjacent two lines road to penetrate between the rail and crossbeam of higher position in every pipe nipple I-steel, and be placed on crossbeam；The veneer of pipe nipple I-steel lower end is extracted out, adjusts position all around so that it is two ends are concordant with outside button rail, afterwards installation buckle and U-shaped card and be fixed；By crossbeam and the step such as pipe nipple I-steel welds outside the pipe nipple I-steel two ends edge of a wing after position is fixing.The present invention is by levelling for two circuits that there is the discrepancy in elevation adjacent during track strengthening, can not only strengthen rigidity and the stability of reinforcement system, reduction of erection time, difficulty of construction and expense, operating characteristics the most also can be greatly lowered strong, and safety is high.
Description
Technical field
The invention belongs to construction of railways technical field, particularly relate to a kind of crossbeam overlay pipe nipple I-steel and look for
The construction method of the horizontal line road discrepancy in elevation.
Background technology
Along with developing rapidly of national economy, in order to meet the demand that urban transportation is built, highway and railway
Grade Separation Project gets more and more, and wears down the most wired frame bridge project and also gets more and more.Framework is set
Bridge many employings jacking construction method, track strengthening construction is then the most important thing of this project.But track strengthening
Period sometimes can run into the problem that in multiply circuit, between adjacent lines, the discrepancy in elevation is bigger, at this moment strengthening construction
Just becoming more difficulty, the method for the most conventional levelling circuit discrepancy in elevation is at circuit reinforcement system middle cross beam
Padding multilamellar sleeper or the lumps of wood between top and the flange of rail, this existing method there is problems in that whole adding
Solid system rigidity is inadequate, and shaking amplitude is big, and later maintenance is complicated, and whole system stability is poor,
Traffic safety can be threatened the most undoubtedly.It addition, also there is employing raising of track in the case of contactless net,
The construction method of track lifting supertronic, but the method has limitation, is only applicable to the situation of contactless net.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of rigidity that can guarantee that reinforcement system
Construction method with the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation of stability.
In order to achieve the above object, the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation that the present invention provides
Construction method includes the following step carried out in order:
1) discrepancy in elevation between two lines road adjacent in the existing line above frame bridge to be placed is surveyed
Amount；
2) crossbeam during unwrapping wire road reinforcement system is worn in the lower section at every circuit；
3) veneer in the lower end colligation of pipe nipple I-steel, to prevent connection electricity；
4) utilize the discrepancy in elevation between adjacent two lines road to penetrate in every pipe nipple I-steel and be positioned at higher position
Rail and crossbeam between, and be placed on a crossbeam, the most thereon between end and rail filling with
The veneer that pipe nipple I-steel length and width are the same, makes veneer reach the height of design, the levelling discrepancy in elevation；
5) veneer of pipe nipple I-steel lower end is extracted out, adjusts position all around so that it is two ends with
Outside button rail concordant, afterwards buckle and U-shaped card are installed and are fixed；
6) outside the pipe nipple I-steel two ends edge of a wing, crossbeam is welded with pipe nipple I-steel after position is fixing
Together；
7) between pipe nipple I-steel and rail foot, pipe nipple plank is padded, and standby tight, thus with chock
Complete whole work progress.
In step 6) in, described crossbeam weld with pipe nipple I-steel after formed fusion length be 5cm～
10cm。
Described crossbeam uses I45b I-steel.
The construction method of the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation that the present invention provides is by circuit
In reinforcing process, adjacent two circuits that there is the discrepancy in elevation are levelling, to replace conventional pad multilamellar sleeper or the lumps of wood
Construction method, the method can not only strengthen rigidity and the stability of reinforcement system, the reduction of erection time, simultaneously
Difficulty of construction and expense can also be greatly lowered.It addition, this method operating characteristics is strong, security performance is high,
There is the most advanced and practicality.
Accompanying drawing explanation
The construction method of the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation that Fig. 1 provides for using the present invention
Time crossbeam and pipe nipple I-steel bonding state side view.
Detailed description of the invention
The crossbeam overlay levelling circuit of pipe nipple I-steel provided the present invention below in conjunction with specific embodiment is high
The construction method of difference is described in detail.
As it is shown in figure 1, the construction party of the crossbeam overlay pipe nipple I-steel levelling circuit discrepancy in elevation of present invention offer
Method includes the following step carried out in order:
1) discrepancy in elevation between two lines road adjacent in the existing line above frame bridge to be placed is surveyed
Amount；
2) crossbeam 1 during unwrapping wire road reinforcement system is worn in the lower section at every circuit, crossbeam 1 uses I45b
I-steel.
3) veneer in pipe nipple I-steel 2 lower end colligation, to prevent connection electricity；
4) utilize the discrepancy in elevation between adjacent two lines road to penetrate in every pipe nipple I-steel 2 and be positioned at high bit
Between rail and the crossbeam 1 put, and it is placed on a crossbeam 1, the most thereon between end and rail
Filling veneer as pipe nipple I-steel 2 length and width, makes veneer reach the height of design, levelling height
Difference；
5) veneer of pipe nipple I-steel 2 lower end is extracted out, adjust position all around so that it is two ends
Concordant with outside button rail, afterwards buckle and U-shaped card are installed and are fixed；
6) by crossbeam 1 and pipe nipple I-steel 2 outside the pipe nipple I-steel 2 two ends edge of a wing after position is fixing
Weld together, a length of 5cm～10cm of weld seam 3 that crossbeam 1 is formed after welding with pipe nipple I-steel 2；
7) between pipe nipple I-steel 2 and rail foot, pipe nipple plank is padded, and standby tight with chock, by
This completes whole work progress.
