Railway tunnel engineers seek ways to prevent salt damage
LUANG NAMTHA, Laos (Vientiane Times/ANN) – Construction of a railway tunnel at the Laos-China border in Luang Namtha province will require the use of materials that are resistant to salt damage, so the track is not affected by the large salt deposits in the ground.
Chinese engineer Wang Xiaodong told Lao and Chinese media recently that they had encountered two salt deposits in Laos but none in China.
This tunnel at the border is the largest in the under-construction Laos-China railway and runs for a distance of 7,000 metres in China and 2,000 metres in Laos.
