A concrete track bed repair method for railway

The present invention relates to a method for repairing and repairing cracks in a concrete road, and more particularly, to a method for repairing and repairing cracks in concrete on a railway track for repairing cracks caused by shocks and vibrations on concrete roads contacted with concrete ties.

When a concrete pavement is partially embedded in a concrete pavement on which a concrete pavement corresponding to a rail is mounted and a corresponding pavement is formed on the concrete pavement, a concrete sleeping pavement due to repeated shocks and vibrations applied to the train along the rail mounted on the concrete pavement It is periodically checked and checked for repair.

Patent Application No. 10-2011-0059637 discloses a crack repairing method for preventing conical sleeper flow which is located on a railway concrete road.

Since the crack repairing method disclosed in the above-mentioned Patent Application No. 0059637 requires a specialist in the field because a filler injection path is inclinedly drilled to the bottom surface of a mounting groove on which a concrete tread is installed using a drill machine, Resulting in an increase in work efficiency when drilled by a non-professional worker.

In addition, since the filler injection path is drilled obliquely from the flat upper surface of the concrete road toward the seating groove, work is difficult and inefficient when the drilling operation is performed only by the experience or the force of the operator.

In addition, since drill traces remain around the entrance side of the filler injection path on the concrete road, there is a problem that the working time is increased due to a work process for finishing to remove drill traces.

An embodiment of the present invention relates to a method of repairing and installing concrete cracks on a railway that can easily work to puncture a filler injection path on a concrete road in order to repair a crack generated in a concrete road.

The embodiment of the present invention relates to a method of repairing and installing concrete cracks on a railway that can be performed even by a non-professional worker in the case where the filler injection path is inclinedly pierced on a concrete road.

An embodiment of the present invention relates to a method of repairing and installing concrete cracks in a railway that allows a filler injection path to be pierced at a predetermined position on a concrete road so that the filler can be injected into the crack as accurately as necessary.

According to an embodiment of the present invention,

A plate having an opening portion formed in a portion contacting the outer surface of the concrete tread, a receiving portion communicating with the opening portion, and an insertion hole formed vertically inside the receiving portion;

A fixture having a lower end fixed to the insertion hole;

A drill for piercing the filler injection path for injecting the filler into the crack portion of the concrete drawing, the drill for piercing the filler injection path for injecting the filler into the crack portion of the concrete drawing, A method of repairing and installing a concrete crack in a railway track using a drill hole guide device having a guide pipe and a guide pipe which are folded and accommodated in the storage unit,

Setting the open portion of the drill perforation guide device to be in a cracked portion to puncture the filler injection path into the concrete pavement;

Securing a gap between both sides of the concrete sleeper and a concrete road in contact therewith;

Drilling the filler injection passageway inclinedly from the upper surface of the concrete surface to the cracked portion by a drill inserted into the guide pipe;

Installing a packer in the filler injection path for injecting a filler into the crack part;

Injecting a filler into the crack through the filler injection passage using an epoxy injector connected to the packer;

And filling the openings of the filler injection passages with an epoxy putty or an acrylic putty when the epoxy injector is separated from the packer after the filler is injected into the cracks and filler injection passages. And a method for repairing cracks in a concrete road of a railway.

The embodiment of the present invention configured as described above has the following advantages.

In order to repair the cracks generated on the concrete road due to the train running along the rail, it is easy to drill the filler injection path on the concrete road, so that the work efficiency can be improved by reducing the working time.

In addition, when drilling the filler injection path slantly in the concrete road, it is possible to work even by a non-professional worker, thereby minimizing labor costs.

In addition, since the filler injection path is precisely pierced at the predetermined position on the concrete surface, the filler is injected to the crack site as needed, and practicality and reliability of the crack repair work can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of using a method for repairing cracks in concrete on a railway track according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 6 (af), a filler 18 such as epoxy, resin, or polyurethane is injected into the cracks generated in the concrete slab 17 on which the concrete sleepers 10 are installed, .

The opening portion 11 of the drill perforation guide device may be cracked so that the filler material passageway 19 may be punched into the concrete pavement 17 to feed the filler material 18 to the crack portion, Quot ;. At this time, the drill perforation guide device may be set on both sides of the concrete slab 17 to simultaneously puncture the filler injection passages 19 to improve workability.

That is, one side of the open end of the plate 14 of the drill-perforated guide device is brought into contact with the outer surface of the concrete guide 17, and a drilling machine (Not shown).

As in S20, a clearance is secured between the outer surface of the concrete sleeper 10 and the concrete pavement 17 which is in contact with the outer surface of the concrete pavement 10. That is, when the filler 18 is introduced into the crack through the filler injection path 19, the filler can be smoothly filled between the concrete tread 10 and the concrete filler 17 through the gap.

The filling material injection path 19 is inclinedly sloped from the upper surface of the concrete slab 17 to the cracked portion by rotation of the drill 20 inserted into the guide pipe 21 as in S30. At this time, the dust of the concrete material generated when the filler injection passage 19 is punctured in the concrete roadway 17 is discharged to the outside through the dust discharge hole 24 formed through the guide pipe 21.

As in S40, the packer 22 is installed in the filler injection passage 19 to inject the filler 18 into the crack. The details of the technique for installing the packer 22 in the filler material injection passage 19 can be practiced by those skilled in the art, so a detailed description thereof will be omitted.

The filler 18 is inserted into the crack through the filler injection passage 19 by using an epoxy injector (for example, a grouting injection pump or the like may be used) connected to the packer 22 as in S50 . The filler 18 passing through the packer 22 and the filler injection passage 19 is provided with a crack generated in the concrete road 17 facing the outer surface of the concrete treadmill 10 and a crack generated in the concrete treadmill 10, The cracks generated in the concrete road surface 17 facing the bottom surface of the concrete block 17 are simultaneously supplied and filled.

The filler 22 is injected into the crack through the filler 22 and the filler injection passage 18 and the epoxy injector is separated from the filler 22 as in S60. At this time, when the epoxy injector (not shown) is separated from the packer 22, the recessed space formed in the opening of the filler injection path 19 is filled with epoxy putty 23 or acrylic putty.

When the curing of the filler 18 filled in the crack and the epoxy putty 23 and the acrylic putty filled in the opening of the filler injection passage 18 are completed as in S70, ) Is ground to be coincident with the upper surface of the concrete road surface 17.
