People's Daily Guangzhou, December 3 (Li Yu, Liu Jie, Guo Dongdong, Xu Weilin, Wang Yu) On December 3, the China-Laos Railway was officially opened to traffic, marking the official transfer of the external power supply project of the China-Laos Railway from the engineering construction and commissioning period to the operation and maintenance stage.
The China-Laos Railway External Power Supply Project was completed on August 31 this year, with an overall line length of about 936 kilometers and an iron tower of 2220 bases, divided into the Chinese section and the Laos section, which were invested, constructed, operated and maintained by the Yunnan Power Grid Company of China Southern Power Grid and the Lao-China Power Investment Company (jointly established by China Southern Power Grid Yunnan International Company and Laos State Power Company).
"The China-Laos Railway External Power Supply Project is like a triathlon competition, from the start of construction to now, we have completed the two projects of safe operation and epidemic prevention and control as scheduled, and then we must focus on ensuring the normalization of power supply for the operation of the China-Laos Railway." Huang Wengang, general manager of the Laozhong Power Investment Company, said.
According to the relevant staff of Yunnan Power Grid Company, in the future, a comprehensive analysis and sorting of the operation mode of the power grid and the balance of electricity will be carried out, and the corresponding accident plan and emergency power adjustment plan will be formulated, and the service and guarantee of the safe use of electricity by the China-Laos Railway will be fully served.
The China-Laos Railway is the first international railway with Chinese investment and construction as the main investment after the "Belt and Road" initiative was proposed, the entire line adopts Chinese technical standards, uses Chinese equipment and is directly connected to the Chinese railway network.
The opening of the China-Laos railway has made Laotian Zhao Mingyan proud and happy. She was a participant in the Laos section of the China-Laos Railway External Power Supply Project and also studied at Tongji University in China. "The traffic is more convenient, and I will take my mother to my school place to see it later." Zhao Mingyan said: "The China-Laos railway is a passenger and cargo transport, in addition to the arrival of personnel, the transportation of goods is more convenient, I can get the Chinese goods purchased online faster, and Chinese friends can also quickly receive Laos specialties." ”
While promoting economic and trade development, the China-Laos Railway will also increase the electricity load along the line, and the follow-up power guarantee is still the key. According to reports, the external power supply project of the China-Laos Railway has been included in the planning and construction of the Yunnan power grid in the next decade at the beginning of the planning.
In addition to the strong grid structure, the power talent reservoir is also very important. During the construction process, the Laos section of the China-Laos Railway External Power Supply Project hired and trained a large number of local employees. "We hope to provide not only a job opportunity, an employment advantage, but also a reserve of skilled personnel for the future construction of the Lao power grid." Huang Wengang said.
After the China-Laos Railway External Power Supply Project enters the operation and maintenance stage, the Lao-China Power Investment Company will continue to explore how to further enhance the added value of the project to the local economic and social development.
"We will work with our Lao partners to do a good job in the operation and maintenance of the China-Laos Railway External Power Supply Project, and at the same time carry out a series of technical exchanges and talent training based on the project, so as to reserve more power professional and technical management personnel for Laos." Huang Wengang said that not only to bring good technology and experience to Laos, but also to combine the actual situation in Laos to form an operation and maintenance management system with Lao characteristics to provide long-term and stable power guarantee for the China-Laos railway.
At the same time, the China-Laos Railway is also a green and low-carbon electrified railway, and it will be a century of development that will derive many "plus", of which the China-Laos Railway external power supply project invested by China Southern Power Grid Corporation has created a number of "plus" bright power roads.
"This 'plus' is environmental protection, upholding the same standards at home and abroad, using the latest technology to reduce the damage to the environment; this 'plus' is still shared, cultivating a group of power talents for Laos, driving local employment, and making the power along the route more abundant." Zhong Xiaotao, senior manager of the international department of China Southern Power Grid Corporation, said.
The overall length of the China-Laos Railway External Power Supply Project is about 936 kilometers, with a total of 2220 towers, and more than half of the lines have to be traveled through the mountains. The project builder adopts a variety of mature technologies to ensure that the local ecological environment receives due care and respect.
In the past, the tower may have to flatten a hill, but now the high and low leg tower unequal height technology is used to determine the length of the four corners of the tower according to the mountain, and only 4 points need to be cleared to minimize the damage to vegetation. After completion, the project builder will also purchase grass seeds suitable for local sowing to restore the original ecology. The tower has also become taller than before, from the previous 30-40 meters to the current 60-80 meters, reducing the damage to the surrounding vegetation and preserving the migration path of animals. "Green water and green mountains are golden mountains and silver mountains in China, and also gold mountains and silver mountains in Laos." Huang Wengang said.
"In Laos, construction workers are paid about twice as much as the average worker, and to increase income, you need to raise the level." Lao employee Ai Ban (transliteration) is the leader of the second bid section of the external power supply project of the Laos section of the China-Laos Railway, "Through participating in the project construction, I have mastered a variety of skills such as tower construction, acceptance and line erection, and I will be more confident and competitive in applying for other projects in the future." ”
The construction of the China-Laos Railway External Power Supply Project has also improved traffic in the mountainous areas of northern Laos, and in addition to the construction of construction roads along the project, the road has also been extended to the villages, making it easier for villagers to transport agricultural and animal husbandry products out of the mountains through small-scale agricultural locomotives, and no longer use people to carry horses.
Msai's hometown is in the village of Gray Flakes in Muang Sai County, Oudomxay Province, Laos, "Previously, there was only one sheep gut trail into the ash flakes village, and when it rained, it all turned into a mud road." Now with the wide gravel road, we can drive tractors to transport rice to Moncey for sale, which is very convenient. ”
After the opening of the China-Laos railway, the business opportunities created will greatly promote the local economic and social development. Tianrui, a scholarship winner of the China Southern Power Grid Company who studied in Kunming, will be a driver of the "Lancang" EMU of the China-Laos Railway. Five years ago, he took the high-speed train from Kunming to Guiyang for the first time, and he still can't forget the scene at that time. "It's fast, and the carriage is full of passengers." In Tianrui's view, "railways and electricity are important foundations to support Laos' economic and social development, and it is believed that after the opening of the China-Laos Railway, it will inject new momentum into Laos' development." ”
