The 6th step, installation lateral adjuster and coarse adjustment
This procedure mainly is that the mounting rail horizontal row is to adjuster and adjustment wire center position and rail surface absolute altitude.The bolt height of spiral adjuster is controlled by the tread absolute altitude control line on the barricade, spiral adjuster straightway is installed 1 every 3 sleepers, rail distance rod, strut spiral adjuster are nearby installed, but strut and pull bar are not wanted overlapping placement, conveniently like this in accurate adjustment, gauge is adjusted, utilize lateral adjuster guarantee the rail rail to.General 12.5 meters instrument sections of track use 7 pairs of spiral adjusters, 7 rail distance rods and 7 gauge struts and 7 pairs of lateral adjusters, can guarantee gauge accuracy and track resistance to overturning like this.Lateral adjuster wants symmetry to place, and the strong point must be firm, because will strengthen support power when adjusting center line, has only the strong point enough firmly just can make about the section of track and laterally moves.Note unified when the spiral adjuster is installed near installing on the sleeper limit, in order to avoid 1 horizontal top reinforcement that influence is laid in 2 sleepers middles, 1 block of 2～3mm steel sheet that 5 * 5cm is square is laid in the place of spiral adjuster lower end kiss the earth, make spiral adjuster frame upright firm, can not sink in concrete cushion when stressed, have enough dynamics to guarantee that the spiral adjuster rises or descends in subsequently coarse adjustment and accurate adjustment process.Through construction verification, 2～3mm steel sheet of adjuster below has played good supporting ﹠ stablizing effect, can produce a desired effect.The rail coarse adjustment is finished after the section of track sets up, according to surveying the center line that sets out in advance, use universal rail gage, Steel Ruler and plumb bob to cooperate to come the coarse adjustment section of track, track forces is good by design standard gauge card, measure the track forces center line with Steel Ruler, on the track forces center line,, depart from the good center line direction of ground bullet by plumb bob and adjust section of track position with the plumb bob suspention, strive for that medium line error is controlled within the 5mm, the rail level absolute altitude is controlled apart from design rail level absolute altitude by super flat spot.
The rail coarse adjustment is a very complicated job, guarantee gauge, about a strand height reach designing requirement substantially, to reduce the track accurate adjustment time, so in the coarse adjustment process, use universal rail gage, simple tools such as Steel Ruler, the string of a musical instrument and plumb bob are adjusted.Sleeper fastening wants order correct when installing, to good position, fastener all adopts standard fastener, so that adopt nonstandard fastener when adjusting at last, allows some leeway for final the adjustment.
The 7th step, track accurate adjustment, the physical dimension of inspection track
Rail laterally between gauge stay bolt bar, rotation gauge holding nut is adjusted gauge back locking to the limit difference scope, fixedly the mutual alignment of rail between horizontal.By lateral adjuster, the lateral attitude of adjusting track integral body is interior fixing to limit difference scope.Concrete steps are as follows: at first build a station, adopt Trimble S
8Total powerstation, GEDO CE track detection car is used, build a station and just entered the accurate adjustment stage after finishing, because the track absolute altitude is the difficult point of ballastless track construction, be not easy to adjust after building moulding, so will carry out strict control to absolute altitude in the accurate adjustment process, through facts have proved that a section of track adjuster is as adjusting the control point, to adopt tracing mode to measure in order to raise the efficiency the accurate adjustment first pass, because the survey data of dolly can and then change along with the adjustment of the section of track at any time under tracing mode, be convenient to control the adjusting range of the section of track like this, make data as far as possible near design load.Data presented comprises line midline, absolute altitude, gauge on the handbook, which and design load differ greatly which just transfer earlier, to adjust line midline earlier generally speaking, with lateral adjuster adjust rail to, because the lateral adjuster symmetric arrangement keeps gauge not change (in design limit difference scope) as much as possible in the adjustment process.And then the adjustment absolute altitude, to adjust by loosening, tighten of screw rod the spiral adjuster, clockwise direction is to tighten to raise rail level, is pine counterclockwise, can reduce rail level.If the absolute altitude deviation will be adjusted the screw rod of two or three adjacent spiral adjusters too greatly simultaneously, can adjust the tread absolute altitude to the right place fast and accurately like this.If adjusting gauge universal rail gage standard at last again adjusts gauge and need not how to move basically.If gauge also has deviation, will reduce or increase gauge by the adjustment of rail distance rod gauge strut.In order to save time, allow the accurate adjustment workman adjust simultaneously, adjust rail and carry out simultaneously to, gauge, absolute altitude, reduce the work holdup, raise the efficiency.Transferred after the first pass with tracing mode, adjust again one time with general mode, adjustment through first pass, rail is just similar basically to, absolute altitude, gauge, and adjustment amount is very little, and purpose is exactly to check one time again, rail is closely to link to each other to, elevation, gauge three, adjust wherein one, other two might be along with variation, so must check one time again.Through twice adjustment, the rail of the section of track just can meet design requirement to, elevation, gauge, can inspection declaration.Geometric parameter for strict control circuit, after finishing, use in concrete receipts face track detection car that how much states of railway roadbed are checked immediately, before the concrete initial set, track can also slightly be transferred, the slight variations that causes during concreting can be adjusted before concrete initial set, so, before concrete initial set, must wipe clean back second hand rail inspection dolly to rail and check one time in order to insure therebetween.
The 8th step, concrete construction
Before the concrete construction, the rail fastening position is covered, prevented that concrete from polluting.
During concrete spouting, adopt vibrating spear to vibrate, guarantee that the sleeper below is concrete closely knit.The time that grasp is vibrated, with coarse aggregate no longer sink, the general position of going up the surface, being shaken of cement mortar is roughly horizontal by shaking into, bubble in the mix no longer comes up is as the criterion.
After concrete vibrating is closely knit, manually concrete surface is wiped one's face for the first time, carry out quadric-plastering and press polish with plasterer's trowel before the concrete initial set, carry out crochet at concrete and sleeper handing-over part with trowel.
After concrete construction is finished, in time unclamp rail fastening before concrete initial set, Stress Transfer exerts an influence to sleeper to the sleeper of below when preventing rail because of temperature difference generation distortion.After concrete construction is finished, concrete is carried out maintenance according to field condition.
