Reduce cars about 85,000 cars every day!Qingdao million Qingdao citizens compete for "Metro Green Ranger"

Every day, nearly one million passengers practice green travel on the busy 284 kilometers of 284 kilometers of Qingdao Metro. Authoritative statistics show that rail transit has gradually become one of the main ways of transportation in Qingdao citizens. Last year, rail transit can reduce car cars about 85,000 vehicles per day.

Qingdao Metro and the general public are also fulfilling the concept of green development. From the construction of the subway line to the operation of the subway; from clean energy, to the development of TOD station city; from the repetitive use of the duster to the construction of a comprehensive assembly station ... green construction, green operation, station city Integrity, clean energy ... As a pioneer of urban green transportation, Qingdao Metro runs the concepts of double carbon and environmental protection throughout the stages of the entire life cycle of the subway project, and fully promote the construction of green urban rails.

The green ledger of the "Green Man"

Ms. Feng, a citizen who lives in Qixia Road, worked at a unit in Shenzhen Road. Every day at 8 am, she sat on Line 3 from Huiquan Plaza, transferred to Line 2 on May 4th Plaza, and reached the unit at 8:50. "Before Line 2 was opened, I drove to and from get off work. At the peak, it took one and a half hours to drive, and it only took 50 minutes to take the subway now."

Put down the steering wheel and scan the code and take the subway. Like Ms. Feng, many citizens use the subway as their main way to commute. The "Qingdao Rail Transit Operation Analysis Report (2021)" by the Municipal Transportation Bureau, the Municipal Metro Engineering Construction Headquarters, the Municipal Public Security Bureau Traffic Police Detachment, and the Municipal Urban Planning and Design Research Institute showed that in 2021, Qingdao Metroquat A total of 66,6720 trains were opened in the year, with a total operating mileage of 21.767 million kilometers, and the total passenger volume of the line network reached 247 million. The average daily passenger volume was 676,000, a year -on -year increase of 78%. After the entire line of Line 1 was opened, the average daily passenger volume of the line network reached 850,000, an increase of 25.7%over the before opening. In 2021, there were 1 billion people in the total number of public transport passenger transportation (east coast urban area, north coast urban area, and the west coast new district). The proportion of rail transit in public transportation passenger transport increased year by year, from 15.4%in 2019 to 24.5%in 2021. According to the latest statistics, since this year, the daily traffic of Qingdao Metro has also risen, and the highest day passenger traffic has exceeded 1.23 million.

There is also a series of exciting data on the green ledger of the "Green Heroes": It is estimated that since the opening of the northern section of Line 3 in 2015, it has reducing a total of nearly 130,000 tons of carbon emissions in 2021, which is equivalent to equivalent to equivalent to the equivalent 350 hectares of forests a year's absorption. Relying on the network of rail transit, Qingdao will jump to a new level in the construction of a low -carbon ecological city. The average travel distance of residents in the central urban area in 2021 increased by 0.74 kilometers compared with 2015, but the average travel consumption of residents decreased by about 4.5 minutes compared with 2015. The time for the same travel distance was about 8.5 minutes. Operating efficiency.

Green Vision of Qingdao Metro

Green, make the city better. Qingdao Metro also determines its own green vision: By 2025, the green low -carbon development system is initially built, and it has become a pioneer of green transportation in the country. In 2028, the goal of achieving the goal of "building a world -class green subway, 30%of power saving and carbon reduction 40%", ranked among the first echelons in the domestic green city rail. In 2050, the green low -carbon development system was fully built, and a green city rail with nearly zero emissions was achieved at a high level.

In the "Building a World -Class Subway Target System" released by Qingdao Metro, "Green" was listed as one of the six goals. In August of this year, Qingdao Metro took the lead in released the "Green Rail Development Implementation Plan" in the domestic rail cities. Enterprises with embodiments also show the determination of green and low -carbon development of Qingdao Metro.

The "Implementation Plan for the Development of the Green City Rail" clarifies the overall goal of the development of the green urban rail development of Qingdao Metro, sets specific indicators such as the overall target setting energy consumption strength, the increase in the proportion of travel, the creation of green buildings, and the use of green energy. Action paths, 64 key tasks are implemented.

Green practice of youth people

Through innovation, Qingdao Metro has implemented the "green" goal, starting with the development and construction of subway and the development and construction of the subway line, and subway operations, creating a "full life cycle" green subway.

Reduce carbon emissions by 20%during the construction process of prefabricated stations, and the use of scum resources to reduce carbon emissions by about 26%compared to traditional disposal methods ... In the construction of Qingdao Metro Line 6 in construction, a series of green technology applications make people's eyes. Light. In April of this year, the main structure of the nationwide comprehensive assembly subway station, the main structure of the Keeli Stail, was successfully completed. Compared with the construction method of traditional paddling parking stations, a standard all -round prefabricated station can reduce the employment by 80%, save about 800 tons of steel, about 800 cubes of wood, reduce construction waste 60%, and reduce carbon emissions by 20%. In addition, the first phase of Line 6 was invested in 32 excavation equipment, of which 20 shields, the tugging length of about 30 kilometers, and the generated shield residue soil was about 803,000 cubic meters. Qingdao Metro Line 6 Company combined with China Railway and residue disposal enterprises to reuse the slag. According to statistics, about 200 kilograms of sand, 300 kg of stone, 100 kg of water, and 270 yuan per ton of shield residue can be produced. Compared with the traditional slag disposal method, carbon emissions can be reduced by about 26%. The bold innovation and attempts of green technology during the construction of Line 6 are a microcosm of Qingdao Metro on the road to exploring green development. The subway is a "big electricity household" during operation. How to use the least personnel to find more people, Qingdao Metro finds answers from all aspects of operation. The first domestic rail industry's first fully independent intellectual property MW -class flywheel energy storage device, which has successfully hanged the Internet, realizes 8 million degrees power saving and 8,000 tons of carbon reduction. The Qingdao Metro will promote the application of flywheel energy storage, new energy management, permanent magnet traction, and photovoltaic wind power construction on the entire network, and implement the "one stop and one case" energy -saving management strategy. Line 13 built a 3 MW photovoltaic power generation system. The single -line installation capacity ranked first in the north. The annual power generation can be generated 3.3 million degrees, and the carbon reduction is about 3290 tons. At the same time, the existing 4 lines of line of photovoltaic planning and design have been completed. The total installed capacity exceeds 16 MW. After the current, it can generate 18.5 million kWh and carbon by about 18,500 tons. The third phase of the line will be used in accordance with the principles of "can be used to cloth". The photovoltaic installation application is expected to reach 25 million degrees, and the carbon reduction will reach about 25,000 tons. In addition, actively carry out research on hydrogen energy technology scenarios to carry out wind power arguments at the vehicle base of Line 11 and Line 13.

In the development and construction along the subway, Qingdao Metro makes full use of underground space, combining rail transit with facilities such as life, shopping, leisure and other facilities to build intensive urban ecological spaces, attract more people to work and live on both sides of the subway, allow more more people People have convenient and efficient public transportation resources, and also help the country's "double carbon" strategy.
