Major projects, run to the goal non-stop!

  On April 26, General Secretary Xi Jinping emphasized at the 11th meeting of the Central Finance and Economics Committee that infrastructure is an important support for economic and social development. It is necessary to coordinate development and security, optimize the layout, structure, function and development mode of infrastructure, and build a modernization system. The infrastructure system lays a solid foundation for building a socialist modern country in an all-round way.

  Since the beginning of this year, there have been frequent reports of good news of major construction projects: the new Anwan Bay Bridge on the Fuzhou-Xiamen Railway will be built without slowing down; The transformation has been accelerated, and the rural 5G base station has been steadily rolled out... Major projects are in full swing, adding impetus and stamina to the Chinese economy.

  Come on, work hard, major projects are at full capacity

  The dawn is slightly exposed, and the construction site of the DC back-to-back Dongguan project in the Greater Bay Area, located in Shatian Town, Dongguan City, Guangdong Province, has become hot.

Fan Jianbin from the production preparation team of the Second Substation Management Office of China Southern Power Grid Dongguan Power Supply Bureau shuttled through the valve tower, busy with the goal of putting into operation at the end of May.

  "During the 'May 1' period, 34 main members of our production preparation team stick to the front line of the project." Fan Jianbin said that the project is currently in the stage of equipment commissioning, and the production preparation group is the main force for the commissioning of the engineering system. "48 valve towers, 7248 power modules , we need to ensure the normal operation of each equipment." The project is an important part of the world's largest flexible DC converter station with the largest substation capacity - DC back-to-back project in the Greater Bay Area.

After the overall project is fully completed at the end of May, it is expected that this year's "West-East Power Transmission" will support no less than 188.3 billion kilowatt-hours of electricity.

  Major projects are running non-stop, and the construction sites are very hot.

  On May 1, the Baihetan Hydropower Station, which has created 6 world firsts, entered the sprint stage for the completion of the main project. The staff raced against time to install and debug the last few generator sets.

As of May 5, the Baihetan Hydropower Station has generated a total of 25.6 billion kWh.

The Three Gorges Corporation strengthened the coordination of grid-connected debugging, actively tracked and coordinated the promotion of power transmission, and strived to put all units into operation as soon as possible.

  At the construction site of the world's tallest dam, the Shuangjiangkou Hydropower Station on the Dadu River, more than 4,000 builders from the National Energy Group fought day and night.

Since mid-April, the daily filling volume of the dam's gravel-soil core wall has exceeded 4,000 cubic meters, with a daily rise of 0.25 meters.

After the completion of the hydropower station, it can increase the power of downstream cascade power stations by 6.6 billion kWh during the dry period, and reduce carbon dioxide emissions by about 7.18 million tons per year.

  Despite the impact of the epidemic, all localities overcame difficulties and seized the construction period, chasing after each other for each major project, and refreshing the "progress bar"-on March 18, all units of the Yalong River Lianghekou Hydropower Station were put into operation; on April 22 On May 2, the Huanggang-Huangmei high-speed railway in Hubei was put into operation, and the old revolutionary area of ​​Dabie Mountain ushered in the "high-speed rail era"; on May 2, Liaoning Hongyanhe Nuclear Power Plant Unit 6 was connected to the grid for the first time, which is the first nuclear power plant and the largest energy source in Northeast China. Investment projects... Major projects will exert their efforts at multiple points, directly driving upstream and downstream industries, and stabilizing investment and growth.

In the first quarter of this year, infrastructure investment represented by major projects increased by 8.5% year-on-year, and the growth rate increased month by month; the number of newly started projects increased by 12,000 compared with the same period last year, and the total planned investment increased by 54.9%.

  Make up for shortcomings and benefit the common people directly

  "Boom..." More than 10 construction machines roared at the construction site of the Tianlin-Xilin Expressway project in Guangxi. More than 30 workers of China Energy Construction were busy and orderly, the machinery and equipment did not stop working, and the project construction did not stop, and went all out Ensure that it is completed and opened to traffic by the end of the year, and strive to open up this "revitalization road, prosperity road, people's heart road, and development road" as soon as possible, and inject new vitality and new kinetic energy into the old revolutionary base area.

  After years of development, China's infrastructure level has made great progress, and the transportation backbone network has taken shape.

However, there are still shortcomings in some areas, especially in the west and mountainous areas, which need to be filled as soon as possible.

  The road is open, and all industries are prosperous.

Major projects in the transportation field are steadily advancing, and people's lives have become more comfortable.

  On April 29, the entire north extension of Chongqing Rail Transit Line 5 was opened.

After the full line of the project is opened to traffic, it will ease the pressure on the north-south passenger flow of Chongqing's rail network and provide strong support for the construction of the Chengdu-Chongqing economic circle.

  Highways form a network and railways are densely distributed. Looking at the land of the state, the transportation network is becoming more and more dense.

The Sichuan-Tibet Railway has been solidly paved, the Yuelongmen Tunnel of the Chenglan Railway has been successfully completed, and the "blank" traffic in the western region is being filled.

During the "14th Five-Year Plan" period, China will add 19,000 kilometers of railway operating mileage, 302,000 kilometers of highway mileage, and more than 270 civil transport airports.

  In the construction of major projects, there are many livelihood projects with strong and weak points.

Especially in the field of social and urban infrastructure, a number of livelihood projects have directly benefited ordinary people.

  Install elevators, replace doors and windows, and build barrier-free ramps—the renovation of old communities emphasizing "one design for one household" is progressing in an orderly manner.

This year, the renovation of old residential areas in Beijing will confirm no less than 400 new districts, start construction of no less than 300 districts, and complete no less than 100 districts.

During the "14th Five-Year Plan" period, the country will basically complete the task of rebuilding about 219,000 old urban communities built by the end of 2000.

  The construction of 5G base stations has provided a faster "information highway" for rural revitalization. By the end of last year, the total number of 5G base stations in the country exceeded 1.425 million, and the actual connected users exceeded 500 million, and new scenarios continued to emerge.

It is expected that more than 600,000 5G base stations will be built this year. While expanding the coverage of densely populated areas such as transportation hubs and shopping centers, the coverage of counties and towns will continue to be improved.

  Increase stamina and boost high-quality development

  The National Development and Reform Commission recently stated that the active expansion of effective investment is not about blindly spreading stalls and projects, nor by implementing large-scale infrastructure investment plans to engage in "flooding"-style strong stimulus, but focusing on key areas and weak areas of economic and social development. A number of investment projects that benefit both the current and the long-term will be implemented in an accurate and orderly manner.

  Consolidate the foundation of agriculture, and press the "fast forward button" for major water conservancy projects.

On April 7, the Huangcaoba Tunnel of the Central Yunnan Water Diversion Project was successfully completed, marking a new breakthrough in the construction of the largest water diversion project under construction in China.

The relevant person in charge of the Ministry of Water Resources introduced that this year will focus on major water conservancy projects and other water conservancy projects, and actively expand effective investment.

From January to March, the national water conservancy investment was 107.7 billion yuan, an increase of 35% over the same period last year.

  Focusing on green development, new energy projects have made great strides.

On March 17, China Huadian Urumqi 1 million kilowatt wind and photovoltaic base project officially started construction, which is also the first multi-functional clean energy base in Xinjiang that integrates "wind energy, photovoltaic, thermal power, and energy storage".

Excavators started up, construction sites were in full swing, and the construction of large-scale new energy projects accelerated, demonstrating to the world China's unswerving determination to pursue a green development path and achieve carbon peaking and carbon neutrality.

  Exploring new technologies, creating new records, and the implementation of major projects are also the process of improving the strength of "Made in China" and "Made in China" and surging innovation, boosting high-quality economic development.

  "First" - In January this year, the first high-altitude wind energy project in China, "Jixi High-altitude Wind Energy Power Generation Demonstration Project in Anhui", was officially launched. The project uses a unique umbrella-ladder structure parachute group to absorb high-altitude wind energy, and then convert it into mechanical energy and electrical energy. Stable and continuous power generation.

"The first" - the world's first pile-beam integrated bridge erecting machine "Gonggong" developed by China Railway has been put into use recently, and successfully completed 10-span operation on the Meilong Bridge in the reconstruction and expansion project of Shenshan West Expressway. "Gonggong" "No." bridge erecting machine has realized a complete set of "aerial" operations of drilling holes, piling, beam erection, and assembling piers, pushing the world's bridge construction technology to usher in major changes.

"First" - In April, the world's first large-scale offshore thermal recovery and development oilfield "CNOOC Lvda 5-2 North Oilfield Phase I Project" was successfully put into production. The successful application of this model will leverage The development of hundreds of millions of tons of ultra-heavy oil resources like "black amber" in the Bohai Bay Basin... One by one, the exciting "firsts", "firsts" and "firsts" demonstrate China's strength and convey China's confidence.

  Live up to the good times and work hard.

With the steady progress of the 102 major engineering projects identified in the "14th Five-Year Plan", China's major engineering construction will usher in more good news!
