Track Mats for FST
Nanchang Metro Line 1

Description

Nanchang Metro Line 1, the first subway line in Nanchang, Jiangxi Province, China has a total length of approx. 28. kilometres. The entire Metro line and its 24 stations are underground.

Solution

More than 140 sites were detected as sensitive areas in terms of ground-borne noise and vibration. A request was made for the installation of FST on highly resilient track mats. Tiantie delivered the track mat USM 1000 W with a very low stiffness to meet the required mitigation measures. Approval measurements have shown an efficiency of 19 dB in higher 1/3 octave bands.
