ApATeCh | Sound walls


Sound walls at the section of the South-East railway "Maslovka-Kolodeznaya"

Advantages:

- Resistance of the structure to deformation
- Possibility of the panels' adoption to the land environment
- Convenience and low cost of maintenance
- Resistance to the stone shots
- Dimensions stability
- Fire resistance
- Resistance to ageing and corrosion
- The surface of the panel is prepared for application of the coating "anti graffiti"

The first lot of sound walls, produced by ApATeCh is installed at the section "Maslovka-Kolodeznaya" of the South-East railway

Comparative analysis
of composite materials' application in the structure of sound walls.

№	Properties	Structures made of Traditional materials	Structures, made of composite materials, Produced by "ApATeCh"
1.	Section interval	2...4 m	Up to 7.5 m
2.	Height of the panel	3...6 m	3...6 m
3.	Material and structure	Three layer-structure Made of aluminum profile with filler or Acrylic glass	Pultrusion hollow profile
4.	Type of basement	Wall footing	Punctiform foundation
5.	Coefficient of the airborne sound insulation	30...33 decibel	30...33 decibel
6.	Assembly of the structure	With the help of lifting equipment	Manual assembly with diminution of the assembly period up to 1,5 times
7.	Portability	Lack of possibility To assemble and dissemble the structure in future	Not less than 10 assemblies and disassemblies with the coefficient of components protection 95%
8.	Maintenance and repairing works (washing, painting, defense from graffiti, replacement of damaged elements)	Ageing due to the impact of stones and caustic dust on the metal covering and hygroscopicity of the filler.	Lack of corrosion Simple repairing works, made by replacement of separate profiles Defense from graffiti
9.	Service life	10...25 years	50 years
