Abstract
The invention belongs to exploitation and resist technology field under colliery and other mine railways, also can be used for the not railway engineering field of affected by exploitation.This method can be used for trunk railway, branch line and private siding.Promote the back and can be country's saving more than ten million yuan every year.Method is at first to replace former sleeper with adjustable sleeper before exploitation.In recovery process, use lifting mechanism and track lining mechanism in time to adjust the height and the planimetric position of rail, make railway satisfy the requirement of standard all the time, treat that the face of land is moved to pull down adjustable sleeper again after basicly stable and change former sleeper.It is good that this method has line quality, safe and reliable, is convenient to mechanized construction and can realizes advantages such as automatic guidance.
Description
Colliery and other mine railways be exploitation and resist technology field down.Some measures wherein also are applicable to the not railway engineering technology field of affected by exploitation.
The major measure of mine coal is under the at present domestic and international railway.1, the state-owned railroads main line adopts the way protection safety of railway traffic of reserved coal pillar.2, railway siding and private siding adopt the artificial way that plays the pad circuit to exploit.Preceding a kind of way makes the coal resources of country and the economic benefit of coal enterprise be subjected to very big loss.A kind of way in back influences the railway normal transport owing to railway track is of low quality, this method is applicable to trunk railway, branch line and private siding, and safe and reliable, and is very little to the railway transportation influence.
The main contents of this method are as follows:
One, replaces former sleeper with adjustable sleeper
Before exploitation, at first give meter surface subsidence amount and the position and the length that influence section.Replace former sleeper with adjustable sleeper then.The replacement method sees second section at second joint for details.
Adjustable sleeper is made up of five parts.1, pedestal is made flute profile or box-shaped, and convex-concave shape or nail-plate shape are made in the bottom.2, lifting mechanism (comprising control member).3, track lining mechanism (comprising control member).These two kinds of mechanisms can select screw, Wedge-type, fluid pressure type or hybrid combination for use.4, rail joist.Available various section steel manufacture.5, rail clip.Major part has clamp and bolt.Require adjustable sleeper to have very high intensity and stability.Every technical index all is higher than former sleeper.The limit value of its adjustable height and track lining can not be excessive.
Two, adjust the gradient, track lining and track lifting
After the surface subsidence.According to the surface subsidence value of observation, the gradient and direction with lifting mechanism and track lining institutional adjustment rail make railway track satisfy the requirement of standard all the time.
When surpassing the allowable value of lifting and track lining mechanism, face of land amount of movement then need raise track.At first between two sleepers that give meter track lifting position, add ballasting before the track lifting, pave compacting.Then standby adjustable sleeper is placed on the centre of two sleepers, ajusts and set level.Relend and help vibrator and progressively the outshot of base bottom is pressed in the ballast aggregate, remove the both sides sleeper after the compacting.Add ballasting and compacting in removal position then.
Three, string rail
Face of land dilatation along the oriented railway direction is passed to rail by adjustable sleeper, and rail gap is changed, and may break fish plate when serious or rail is bent.Need take following three measures for this reason.
1, in time adjusts the rail clip position according to the surface deformation value of observation, make the displacement of adjustable sleeper pass to rail less as far as possible.
2, change the rail gap joint form.Realization engaged or joggle closes or other forms of interspersed combination for vertical tongue and groove in flush joining of general-duty.Can increase the width of rail gap like this, also can eliminate the vibrations that produced when train wheel is crossed rail gap.
3, when blind seam or rail gap width overrun occurring, need go here and there rail.
Four, withdraw from adjustable sleeper after the process of adopting finishes, change former sleeper.
Five, other measures
1, suitably increases the width of railway ballast, and reinforce compacting.
2, select that quality is good for use, particle diameter is 4～8 minutes ballast aggregate.
3, each sleeper all need be qualified through laboratory inspection.
4, the adjustable sleeper of a cover at first is used for private siding, after railway siding is on probation, can be used for trunk railway again.
Claims (4)
1, adjustable sleeper is characterised in that:
(1) adjustable sleeper is by pedestal, lifting mechanism, and track lining mechanism, five of rail joist and rail clips etc. are basic partly to be formed.
(2) construction method is at first to replace former sleeper with adjustable sleeper; In surface movement process, use the level and the superelevation of lifting mechanism and the track lining institutional adjustment rail gradient, direction and two one steel rails then; Treat to change former sleeper after surface movement process finishes.
2, feature according to claim 1 changes the flush rail joint of present general-duty into the tongue and groove joint or joggle closes.
3, feature according to claim 1, the bottom of pedestal make convex-concave shape or nail-plate shape, with machinery outshot are pressed in the ballast aggregate.
4, according to claim 1 and the described feature of claim 2, also be applicable to the not railway engineering of affected by exploitation.
