Noise Reduction Tunnel

Experience the new concept of soundprrof walls and soundproof tunnels with us!

Upper part of Soundproofing tunnel leakage prevention

(No leakage certification (KCL) for dynamic pressure, static pressure watertight test)

No risk of rusting by using aluminum profile as main member.
Prevention of leakage by using direct waterproof screw for finishing part.
Prevention of water leakage by the fourth reinforcement of the caulking after 2nd and 3rd reinforcement such as E.V.A pad, waterproof tape and aluminum cover (E.V.A pad combination) from the bottom.
100% leakage prevention from silicon removal.

Soundproofing tunnel leak check path

It is the inspection passage installed on the upper or side of the soundproofing tunnel to maintain the soundproofing tunnel.
The soundproof tunnel leakage prevention inspection line is an installation method that prevents leakage caused by the installation of the inspection line and prevents the leakage of water which result in cost saving for maintenance.

Soundproof Tunnel Fixing Angle

It can be mounted on a transparent soundproof panel (PC or PMMA), and it is possible to maintain a solid assembled state, thereby improving assembling workability.
It is a ceiling leakage prevention method of a soundproof tunnel that can prevent water leakage due to the flow of a transparent soundproof panel (PC or PMMA) as the initial state is maintained continuously after the assembly is completed.

Solar Panel on the top of the soundproof tunnel

Sound-absorbing tunnels using eco-friendly electric energy created by solar light (solar energy), the source of clean energy.

Soundproof Tunnel Sunshade

In order to ensure the safety of the driver by the sunlight coming from the upper PC of the tunnel during the tunnel run, a plate of perforation pattern is installed between the upper support and the pillar of the tunnel to reduce the sunlight coming in between the support.

Tunnel junction

The sound insulation tunnel developed to facilitate the stability and maintenance of the sound insulation tunnel has expanded the concept of the expansion joint used in the road, thus maintaining the structural stability of the sound insulation tunnel due to the change of the road.

Sound absorbing tunnel shock absorber

It is a kind of guardrail installed on the shoulder and the middle part of the bridge when the soundproof tunnel is installed.
It is aimed to mitigate the impact of the vehicle and minimize the damage of the support when the vehicle collides in the tunnel.
