China Railway Construction Unit Pens USD825 Million Repair Contract in Zambia

(Yicai Global) March 4 -- A subsidiary under China Railway Construction has signed a USD825 million contract to repair three railroads in Zambia after landing a track construction deal in Nigeria just last week.

China Civil Engineering Construction and the Zambian Ministry of Transport and Communications signed off on the terms, which will see the Chinese firm design, procure for and carry out the restorations, its parent said in a statement yesterday.

Shares in China Railway Construction [SHA:601186] were up 3.13 percent at CNY10.86 (USD1.56) when the Shanghai bourse closed for lunch.

The three tracks span 648.3 kilometers and the firm believes it can complete the repairs within eight years. They each have a maximum design speed of 118 kilometers per hour for passenger trains and 80 kilometers per hour for freight trains, according to the statement. A railroad connecting Livingstone and Kafue Bridge makes up most of the project, with two smaller lines connecting Livingstone and Mulobezi, and Masuku and Choma, making up the remainder.

The subsidiary has been pushing for new infrastructure deals in Africa and last week signed a construction contract for the Lagos-Kano railway in Nigeria, which it expects to complete in about three years.

It also won a USD2.3 billion contract in Zambia in November 2016 to build a nearly 389 kilometer railroad, which was China Railway's first major deal in the country since it built the Tanzania-Zambia Railway in the 1970s.

China-Laos railway tunnel's border drilling finished
Source: Xinhua| 2020-05-20 12:13:13|Editor: huaxia

VIENTIANE, May 20 (Xinhua) -- China Railway No. 2 Engineering Group (CREC-2) told Xinhua that it has drilled through the Friendship Tunnel from northern Laos to the border line with China on Wednesday.

After 37 months of hard work, the China-Laos Railway Friendship Tunnel, which runs through the Laos-China border and is constructed by CREC-2 and designed by China Railway Eryuan Engineering Group, was bored from northern Laos' Boten, some 370 km north of Lao capital Vientiane, to the border with China on Wednesday.

The progress has, hence, laid a solid foundation for the completion of the railway by December 2021.

The Friendship Tunnel, with a total length of 9,959 meters and 2,425 meters of which belonging to the Lao section, and with the maximum burial depth of 243 meters, is located in the forests in northern Laos.

In the depth of the mountains, the tunnel meets salt layer with thickness of over 100 meters and salinity of over 80 percent, which is extremely harmful to the safety of the tunnel structure.

In view of the poor geological conditions of the tunnel and the frequent occurrence of water inflow and slump, the project department strengthened the geological prediction and information collection. They held several meetings to refine and optimize the construction plan to ensure the safety, quality and progress of the project.

With the COVID-19 epidemic setting in, the Chinese engineering companies also comprehensively implemented epidemic prevention and control to ensure tunnel construction.

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-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.

The electrified passenger and cargo railway is built with the full application of Chinese management and technical standards.

The project started in December 2016 and is scheduled to be completed and open to traffic in December 2021.

VIENTIANE, June 21 (Xinhua) -- China Railway Guangzhou Engineering Group (CRECGZ) drilled through the Ban Nakok Tunnel, the second longest tunnel along the China-Laos railway, on Sunday.

The 9,296-meter Ban Nakok Tunnel, in northern Laos' Oudomxay Province, some 400 km north of the Lao capital Vientiane, went through harsh geological conditions which made its construction a key bottleneck of the railway.

The Ban Nakok Tunnel past through four fault zones and complex geological situation which brought huge difficulties to the construction and the safety control.

Since the start of its construction in May 2017, the CRECGZ project department has actively carried out scientific and technological innovations to overcome the difficulties, and bore scientific research results such as "key technologies for soft rock tunnel construction in Southeast Asia's rainforest" to effectively accelerate construction.

Since the beginning of this year, to overcome the impact of the COVID-19 pandemic, the project department simultaneously carried out epidemic precaution and construction, especially making full use of the advantages of localization, purchasing large quantities of local construction materials such as sand, gravel and cement and recruiting more local workers to promote cooperation with localities.

The China-Laos Railway is a strategic docking project between the China-proposed Belt and Road Initiative and Laos' strategy to convert itself from a landlocked country to a land-linked hub.

The 414-km railway will run from Boten border gate in northern Laos, bordering China, to Vientiane with an operating speed of 160 km per hour.

The electrified passenger and cargo railway is built with the full application of Chinese management and technical standards.

The project started in December 2016 and is scheduled to be completed and open to traffic in December 2021.

The high-speed rail project linking Indonesia's Jakarta and Bandung, carried out by Chinese builders, has successfully balanced construction progress with COVID-19 prevention and control measures this year.

Thanks to excellent prevention measures, strict management, thoughtful planning and reasonable process scheduling, the construction project has made steady progress as the building of the main roadbed, bridges, tunnels and stations have moved forward as planned, China's top economic planner, the National Development and Reform Commission, reported on Friday.

So far, the No 5 tunnel and No 3 tunnel have been completed, with the DK23 continuous beam on many supports also having been closed.

In addition, the No 1 tunnel shield and track-laying work have achieved phase milestones.

According to a video post by the commission, the project stores three months' worth of relevant medical supplies and living materials to support the construction workers' living and working.

The Jakarta-Bandung railway is one of the key projects under the China-proposed Belt and Road Initiative and one of the Indonesian government's national strategic projects.

The railway line is 142.3 kilometers long and will be used for trains with a maximum speed of up to 350 km an hour. The journey between Jakarta and Bandung, which previously took more than three hours, will be shortened to 40 minutes.

In the future, China and Indonesia will continue to work together and speed up project construction in a safe manner in order to put the railway into use as early as possible, the commission said.

On Tunnel Boring Machine (TBM)

Have you ever wondered how a high-speed railway tunnel is built? Let us introduce you how a Tunnel Boring Machine (TBM) works.
With a snake-shape body and a snail-like speed, the TBM excavates through the soil, “eats” the gravel and clods, and stores it into its “belly”. Check out the video to learn more about how a Tunnel Boring Machine works.
.
In 2008, “CREC NO. 1”, the first compound Earth Pressure Balance (EPB) TBM, designed and made by CREC, rolled off the assembly line. Since then, CREC has gradually grown to become a major TBM manufacturer and reached new heights. Orders have exceeded 1,000, the products have been exported to 21 countries including Indonesia, Singapore, the UAE, Italy, France and more. The market share ranks the first in the world for three consecutive years from 2017 to 2019.
