LUANG PRABANG, Laos, Nov 9 (NNN-XINHUA) – China-Laos railway tunnels’ construction, continues to make lots of breakthroughs, as one more major tunnel was drilled through on Friday, in the tropical mountains of northern Laos.<\/p>\n\n\n\n
A Chinese railway engineering company, China Railway No. 8 Engineering Group (CREC-8), bored, Ban Ka No. 1 Tunnel, near the ancient Lao capital of Luang Prabang, some 220 km north of the capital, Vientiane.<\/p>\n\n\n\n
This marks another important milestone in the tunnel construction of the China-Laos railway. With a length of 4,585 metres, it is the second longest tunnel on the rarely-inhabited peninsula area, half-circled by the Mekong River.<\/p>\n\n\n\n
The poor transportation infrastructure, without bridges connecting nearby Luang Prabang and roads in the area, the living and production conditions on the peninsula have been quite hard.<\/p>\n\n\n\n
What’s more, the Ban Ka No. 1 Tunnel has to pass through unfavorable geology, creating lots of difficulties to the Chinese engineering company, CREC-8. It is listed as a high-risk, difficult and bottle-neck project for the China-Laos railway construction.<\/p>\n\n\n\n
During construction, hydraulic discharge and mud cleaning have brought difficulties to the Chinese engineers.<\/p>\n\n\n\n
However, with efforts made by the Chinese and Lao sides, the tunnel’s construction was carried out scientifically, and rapidly. Last May, the CREC-8 achieved first place with over 1,000 metres bored into a tunnel from a single working face in the Ban Ka No. 1 Tunnel, which laid the foundation for its completion.<\/p>\n\n\n\n
Especially for the tunnel construction, the China-Laos railway has holed through around 40 tunnels so far, out of its 76 tunnels with a total length of 198 km.<\/p>\n\n\n\n
The Boten Tunnel, the first major tunnel over 5,000 metres along the China-Laos railway was drilled through on Mar 21, by China Railway No. 5 Engineering Group (CREC-5). In Oct, 2018, the CREC-5 also completed the first over-1,000-metre tunnel along the China-Laos railway, the Nateuy No. 1 Tunnel, with a length of 1,158 metres, some 360 km north of the Lao capital Vientiane.<\/p>\n\n\n\n
In Feb, 2018, the Chinese engineering companies started inside-tunnel construction for all major tunnels along the China-Laos railway, and started construction of all over-one-kilometre tunnels.<\/p>\n\n\n\n
The China-Laos Railway is a strategic docking project between the China-proposed Belt and Road Initiative and Laos’ strategy to convert from a landlocked country to a land-linked hub. The 414.332-km railway, with 198-km tunnels and 62-km bridges, will run from Boten border gate in northern Laos, bordering China, to Vientiane, with an operating speed of 160 km per hour.<\/p>\n\n\n\n
The project started in Dec, 2016, and is scheduled to be completed and opened to traffic in Dec, 2021.– NNN-XINHUA <\/p>\n","protected":false},"excerpt":{"rendered":"
