Part, reduces after inspection Alignment Design is qualified and exports after track plates thickness of slab and reserved 3mm at rail, fastener height and track
Base-plates surface is rule the altitude data of grid in length and breadth.Covered with wire center line coordinates for horizontal location reference measurement track plates
Pedestal altitude data, is compared with the output data (theoretical value) of Survey Software, marks more than super theoretical value 2mm of the actual elevation of pedestal
Region and reduce its elevation, make pedestal elevation meet ± 24 assembly precisions requirement.Base-plates surface flatness checks by hand
Method be 2m guiding ruler coordinate clearance gauge it is allowed to maximum deviation be 6mm；In the region of configuration stick viscoplasticity bed course, 1m guiding ruler is joined
The maximum deviation closing clearance gauge is 2mm.
Step 6：Track plates and pedestal assembly simulation
The pedestal altitude data covering according to track plates name thickness of slab, track plates lower surface flatness data file and this plate
Track plates displacement under file and track plates weight, bed course simulated behavior bogie load action, proposes base-plates surface viscoelastic
The allocation plan of property bed course.
Step 7：In base-plates surface construction lofting
Net is controlled to carry out track centerline coordinate points and track plates installation unwrapping wire in base-plates surface using CP III, and according to rail
Guidance tape and pedestal assembly simulation result carry out the construction line-putting of bed course arrangement.
Step 8：The configuration of viscoplasticity bed course
Using the assembling pad of two kinds of thickness specifications of 5mm, 9mm and the polyester sheet of two kinds of thickness of 1mm, 2mm, can single laying dress
Join pad, also can combine from polyester sheet and constitute viscoplasticity bed course although the thickness of assembling pad is different, but the vertical stiffness of unit area
Identical.Press the construction line-putting configuration viscoplasticity bed course of bed course arrangement in base-plates surface.
Step 9：Track plates are in place
According to the result of track plates and pedestal assembly simulation, hang by track plates numbering and the end to end order of fabric swatch along the line
It is attached to fortune wooden handcart, then removes stage makeup and costume and be transported to plate paver, make track plates in place.Borrow the nylon sleeve or specially pre-buried of rail fastening
Nylon sleeve installs measuring prism, with total powerstation cooperation, checks track Board position, and utilizes programming Control system accurate adjustment track
Plate.Or by total powerstation using CP III control net measure track center line coordinate points input accurate adjustment car control program, can make
Track plates are mounted directly, accurately in place.
Step 10：Track plates spacer pin or positive stop lug boss construction
After in-orbit guidance tape is accurately in place, in-orbit guidance tape is reserved and is run through the base drilling of circular hole position and install spacer pin, also may be used
Option board end or plate side setting positive stop lug boss, and the gap between plate and position limiting structure adopts polyurethane material to fill, or adopt
Use other elastomeric materials.
Step 11：Trackside gutter or fill and lead up
Lay separation layer in accurate adjustment track plates both sides in place, make plate and cast-in-place concrete gutter or fill and lead up structure every
From.After in rail laying, by concrete construction machinery mouldless shaping ditch, track plates both sides also can not set structures in gutter.
Step 12：Track accurate adjustment and gapless track
By many contacting pieces, gapless line or standard gauge are fixedly mounted on track plates, coarse adjustment and accurate adjustment rail, meet rail
The requirement of road geometry flexibility index.Constitute gapless track using spark contact welding welded rails.
Assemble that board-like track structure is succinct, design sequencing, production plant, mechanization of building operation and IT application in management.Logical
Cross programming Control pedestal pave, cloth pad, fabric swatch, track plates adjustment and track geometry ride comfort, build Track desigh construction, check and accept
The database sharing with operation maintenance.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of the utility model claims.
