3, planeness reaches 3m, and straight chi detects the railway ballast planeness and is not less than 10mm; In the position of every sleepers, place a chock, place square steel on the chock, the integral level degree that keeps square steel is in 10mm; Square steel is put with bent following strand along the straight thigh of going up of track switch;
C, assemble in situ track switch
Sleeper and rail are lifted on the assembly platform, carry out the assembling of track switch on switch assembly platform, after assembling is finished the joint of track switch inside is welded, the track switch after welding is finished keeps track switch direction, level in 1mm by the hydraulic pressure that the is positioned at both sides oil cylinder integral lifting of all rising;
Whole road on d, the switch location
Behind the track switch integral lifting, manually go up the tiny fragments of stone, coal, etc. and replenish railway roadbed and make firm by ramming; Subsequently track switch is opened straight strand, utilize engineering train that track switch is carried out throughput and be no less than 50,000 tons pressure road, press the road to finish back line direction, level, gauge error in 1mm;
The conversion equipment of e, track switch is installed
Track switch is carried out the installation of conversion equipment after the meticulous adjustment of process;
The maintenance of f, track switch
Do the periodic maintenance maintenance after track switch is opened, comprise the gauge and the level that keep track switch, track switch is made firm by ramming.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, compares in the prior art directly laying a switch on railway ballast, the present invention is provided with switch assembly platform in position, track switch is assembled at switch assembly platform, this track switch assembling mode has improved the adjustment precision of track switch greatly, avoid the track switch distortion, make the location of track switch more accurate, kept the track switch globality.
2, the inventive method utilization hydraulic test integral lifting of all rising, the single-point of comparing in the prior art raises track, and can effectively avoid track switch to deform in whole road, can guarantee the physical dimension of track switch, can make the track switch absolute altitude be easy to control again.
3, the inventive method comprises periodic maintenance and maintenance after the track switch laying, makes track switch in use keep how much good states, thereby guarantees that the every performance indications of track switch all can reach designing requirement.
4, the enforcement of the inventive method can utilize existing mechanical equipment, invest low, the efficient height.
Description of drawings:
Fig. 1 is an assembly platform of the present invention vertical section schematic diagram.
Fig. 2 puts schematic diagram for square steel of the present invention.
Fig. 3 is a track switch schematic top plan view of the present invention.
Number in the figure: 1 roadbed body, 2 rubble railway ballasts, 3 chocks, 4 square steel, 5 switch ties, 6 rail.
Below, in conjunction with the accompanying drawings the present invention is done a step explanation by the specific embodiment.
The specific embodiment:
Present embodiment is operated as follows:
1, circuit overlays
Utilize interim short row to overlay alternate route in the track switch scope, engineering train transition on the alternate route that overlays is passed through, and then the circuit in the track switch scope is carried out maintenance according to the program of " five smash three steady ", makes the compactness of railway roadbed reach requirement;
2, remove short row, set up switch assembly platform
Referring to Fig. 1, at first utilize crane to remove short row, on roadbed body 1, shakeout railway roadbed then with rubble railway ballast 2, make the railway roadbed absolute altitude than sleeper at the bottom of low 10cm, ballast ramming makes its compactness reach 1.7g/cm
3, 3m is straight, and chi detection railway ballast planeness is not less than 10mm.
In the position of every sleepers, place a chock 3 that 5cm is high, the length of chock 3 is 400mm, width is 200mm;
Place the high square steel 4 of 5cm on chock 3, super flat with level gauge, the integral level degree that keeps square steel 4 is in 10mm; Square steel 4 is put with bent following strand along the straight thigh of going up of track switch, as shown in Figure 2, and every long 6m of 1#-20# square steel among the figure, every long 3m of 21#-22#.
This mode can make track switch just can keep good general frame structure at the assembling initial stage, avoids distortion.
3, assemble in situ track switch
Lay to desire to make money or profit according to track switch and with gantry crane switch tie 5 and rail 6 are lifted on the assembly platform, the effect of protecting sleeper is played with on the rubber sleave in the place that suspension centre contacts with switch tie 5.
Utilize exothermic welding that the joint of track switch inside is welded, finish the assembling of track switch;
4, track switch integral lifting
After track switch assembles, utilize 20 hydraulic pressure to all rise oil cylinder with the track switch integral lifting, each ten of track switch both sides, oil cylinder, placement location as shown in Figure 3, Fig. 3 intermediate cam shape symbol is for placing the position of hydraulic jack, whole track switch does not contain no occipital region and has 115 switch ties, the absolute altitude that hoists utilizes the high precision level gauge to control, and whole track switch level is remained in the 1mm.
The mode of this integral lifting makes track switch keep general frame indeformable in the process of hoisting, thereby the member physical dimension that guarantees track switch is correct, to guarantee the reliable use of track switch.
5, whole road on the switch location
Behind the track switch integral lifting, at first utilize the artificial tiny fragments of stone, coal, etc. of going up to replenish railway roadbed, utilize the flexible axle tamping tool to make firm by ramming then, strengthen making firm by ramming with the track switch diesel tamping machine again, be no less than five times.
6, the meticulous adjustment of track switch
Track switch is opened straight strand, utilize engineering train that track switch is pressed, press the road speed per hour in 5km/h, be no less than 50,000 tons of throughputs, per 10 pressure roads all carry out meticulous adjustment to circuit, all press and finish back line direction, level, gauge error in 1mm;
7, the conversion equipment of track switch is installed
After the meticulous adjustment of track switch, carry out the installation of conversion equipment according to construction drawing;
8, the maintenance of track switch
After track switch is opened, for guaranteeing that track switch does not produce distortion in driving, to track switch periodic maintenance maintenance, adopt track detection car to measure gauge, direction and the level of track switch, utilize the internal combustion railroad switch tamping tool that track switch is made firm by ramming, the track switch quality is remained well, with special-purpose turnout tamping car track switch is made firm by ramming more at last.
This mode can make the track switch that lays in use constantly maintain a good state effectively, avoids track switch to produce the memory disease in formal operation driving, to satisfy the speed-raising requirement.
