The construction of several major projects to expand domestic demand, stabilize growth and benefit people’s livelihood has been accelerated.

CCTV News:At present, from the fields of transportation to energy, the progress of several major engineering projects has been constantly refreshed, providing strong support for expanding domestic demand, stabilizing growth and benefiting people’s livelihood.　

Liu Jiashan Tunnel of Chongqing-Guizhou Railway Control Project runs through.

On July 2nd, Liu Jiashan Tunnel, the control project of Chongqing-Qianjiang Railway, was completed, and the main project of Chongqing-Qianjiang Railway was 80% completed.

Huang Chenghua, Deputy Commander of Wulong Command of Chongqing-Guizhou Railway Company:Chongqing-Guizhou Railway is an important part of the "eight verticals and eight horizontals" channel of the national railway network, and it is also an important infrastructure connecting the Maritime Silk Road and the Yangtze River Economic Belt, which makes the passenger traffic between Chengdu-Chongqing urban agglomeration and Changsha-Zhuzhou-Xiangtan urban agglomeration faster and more convenient.

While the railway network is becoming more and more dense, a number of key highway projects are being accelerated.

Hami, Xinjiang: Four highways are completed and opened to traffic, forming a high-speed ring road in eastern Xinjiang.

In Hami, Xinjiang, a few days ago, Wutong Daquan on S519 Line — Four highways, including Shaquanzi Expressway connecting line, were completed and opened to traffic, marking the further improvement of the outer ring of Hami resource highway and the road network in eastern Xinjiang. After opening to traffic, the organic interconnection between Jingxin Expressway on G7 line and Lianhuo Expressway on G30 line in the north-south direction has been realized. With the opening of several highway projects, Hami has built a "one-hour economic circle" in the core area of one district and two counties and a circular channel for the transportation of peripheral resources industries, and the modern transportation network system is more perfect.

Yudu, Jiangxi: Jiji Bridge is officially opened to traffic, and a river-crossing expressway is added.

Recently, the assembly bridge in Yudu, Jiangxi Province was successfully completed and opened to traffic, which was the starting point for the assembly of the Central Red Army’s Long March — — A new landmark was added to Yudu, and the opening of the Jiji Bridge provided an important travel guarantee for the interconnection between the new and old local cities.

Golmud, Qinghai: The world’s largest demonstration project of liquid air energy storage started.

In Golmud City, Haixi Mongolian and Tibetan Autonomous Prefecture, Qinghai Province, the demonstration project of 60,000 kW/600,000 kWh liquid air energy storage was officially started. The project is equipped with a 250,000 kW photovoltaic project, which successfully breaks through the equipment constraints of large-scale amplification of liquefied air energy storage systems from 100 kW to 10,000 kW, and effectively improves the level of major technical equipment in the energy field. It is understood that the technology of liquefied air energy storage project has many advantages, such as large-scale, long-term, low-cost, unrestricted by geographical conditions, etc., especially in the fields of renewable energy consumption and peak shaving of power grid.
