Description
Technical field
The present invention relates to the maintenance of unballasted track bed plate, the specifically a kind of type unballasted track bed plates of CRTS III drop supercharging
Fill curing means and fill the method for supporting.
Background technology
The plate-type non-fragment orbits of CRTS II are to be laid on precast track plate now by cement emulsified asphalt mortar adjustment layer
In the concrete support layer or the reinforced concrete footing of cast-in-place post that field paves, and adapt to the vertical of ZPW-2000 track circuit requirements
Linking-board type ballastless track structure form.
Its main technical requirements：
1. track plates width is 2550mm, thickness is 200mm, and standard gauge guidance tape length is the 6450mm, (compensation of heterotypic rail guidance tape
Plate) length is according to specific laying paragraph reasonable disposition.Track plates should be met using C55 grades of concrete《Passenger dedicated railway line
CRTS II plate-type non-fragment orbit concrete railway board (having shoulder block) provisional technical conditions》(scientific and technological base [2008] 173) will
Ask.
2. mortar adjustment layer design thickness is 30mm, and should be met《The plate-type non-fragment orbits of passenger dedicated railway line CRTS II
The provisional technical conditions of cement emulsified asphalt mortar》(scientific and technological base [2008] 74) requirement.
3. supporting course top surface width is 2950mm, bottom width is 3250mm, and thickness is 300mm, and should be met《Passenger traffic
The provisional technical conditions of special line railway ballastless track supporting course》(scientific and technological base [2008] 74) requirement.
4. for the concrete structure in rail system, in terms of the selected of material, construction technology and durability measure
According to《Railway concrete durability design of structure temporary provisions》(iron construction [2005] 157) and " on issue《Railway is mixed
Xtah Crude Clay structure durability Design temporary provisions》Deng the notice of two Environment in Railway Engineering Construction standard partial revision provisions " etc. specification hold
OK.
5. superrelation on curve is set on subgrade bed top layer.
6. rail system should set waterproof and water drainage system of good performance.Straight line location is adopted using two row drainings, 3 in Curve Segment
With three row drainings.
Left and right line bearing interlayer fills mineral compound, and its top surface uses C25 Concrete Filleds.Along fill concrete
Expansion joint laterally is respectively provided with every 5m between road longitudinal direction and track plates and along circuit, using fill asphalt method.Supporting course on the outside of track
Surface and road bed are surface-treated using emulsified asphalt.
Above-mentioned technical requirements need to set up on the basis of relatively good maintenance, wherein in traditional concrete curing, typically
Using geotextiles covering watering maintenance, or using film covering watering maintenance.But, conventional concrete curing method, which exists, to be permitted
Many shortcomings, it is difficult to reach the high standards that construction unit conserves on the plate-type unballasted track bed plates of CRTS III, display is such as
Under：
（1）Technique is outmoded, and standard is relatively low
Routine, which covers cloth maintenance or peritonaeum maintenance, needs someone's whole process to carry out spray water curing, because artificial treatment occupies leading, supports
The level of shield is uneven, and efficiency of construction is very low, it is necessary to take a substantial amount of time.In practical operation, occur unavoidably
Maintenance speed does not catch up with situations such as moisture evaporation speed, workman are slacked off, and dehydration is ftractureed during causing bedplate concrete curing,
It is difficult in adapt to the maintenance construction requirement of existing high standard.
（2）Water resource waste is more serious
In work progress, due to needing bedplate being chronically at moisturizing state, it is necessary to supplement water before dehydration inside covering.
And plastic sheeting water-holding capacity is poor, it is difficult to realize and continue moisturizing, it is necessary to continuously water；Geotextiles water-holding capacity is slightly strong, and summer waves
Hair speed is exceedingly fast, it is also desirable to substantial amounts of water resource；The two is combined in time, is manually needed when being sprinkled water by film and geotextiles
Separate, cause to conserve inefficiency.
（3）Automaticity is low
Whole process maintenance is required to artificial progress, and labor intensive is huge, it is impossible to the requirement of high-volume factory operation is met, while night
Between maintenance be very difficult to monitoring.
The content of the invention
