Variable pad

The variable pad can increase train driving and track stability by adjusting the height of any thickness by inserting a pocket in the spaced area between the sleepers and bridges’ girder or the rail sagging spots on the sleepers and roads, and then injecting resin.

Product Features

Evenly support the rail by correcting the manufacturing error and construction error of the track
Minimize vibration and noise due to separation of sleepers and bridges, and sleepers and roads
Precise construction on the curved part is possible, preventing track distortion
Can be used semi-permanently with one time construction

Precise fastening of fasteners
Precision construction on the bridge

Installation of variable pad

The variable pads in the bridge are installed in the following order (Refer photos).
Fastening of fasteners approximately 40 minutes after resin injection, and train operation is possible after 2 hours.

Tie filler

It is a product developed to fill the gap by filling the gap between the sleeper, slab, and the vibration-proof pad with a filler (tie filler) of appropriate physical and mechanical properties, and to maintain structural safety.

Tie filler features

Excellent fluidity that can fill even minute gaps
Excellent hardening strength and excellent track durability
Due to the characteristics of early complete strength, it is possible to pass the train from about 40 minutes after injection of the tie filler
Excellent adhesion with sleepers and concrete to ensure the integration of track structure
If injected into the cracks of the sleeper, it prevents the spread of damage to the sleeper and extends the service life

Spike Filler

A product that can be easily repaired a damaged hole on wooden sleeper or broken buried case on PC sleeper.
- For wooden sleepers and PC sleepers: Spike wood filler
- For synthetic resin sleepers: Spike filler

Product Features

Spike WoodFiller / filler resin has little shrinkage after hardening, so its filling rate is excellent
Excellent clamping force (4.25ton pull-out load)
Maintenance is possible in a short period of time, so it is possible on serviceline.
Simple usage and excellent durability.

Method of Uses

After cleaning the drilling hole at the site, drill the inside of the hole in an 8-shape shape
After mixing A and B by 1:1, inject into the damaged sleeper hole
Maintenance is possible in a short period of time, so it is possible on service line.
When hardening is completed, drilling and refastening the fastener (hardening time: about 40~60 minutes)

Ballast Bond

The ballast Bond is applied to the high-speed driving section, the tunnel entry and exit section, the connection section of the ballasttrack and the concrete track, and the place where the track lateral resistance is a problem in order to efficient management of the ballast track.

Product Features

The ballast bond is made of urethane resin, and the gravel and gravel are bonded by a point-structure adhesive method, allowing the gravel to be separated during MTT work.
One-component type, no complicated weighing or equipment is required, and manpower construction is possible with a simple spreader.

Penetration of the ballast bond
Gravel separation is possible when MTT work

Usage of the ballast Bond

Stabilize the ballast track by consolidating the scattering points with a tie temper or compactor before use.
The amount of ballast bond is distributed according to the required penetration depth.
The train can be operated 2 hours after the bond is spread.
Avoid construction in rainy weather, and not affected by rainfall after complete curing (after 2 hours).
