Chengdu rail transit: Taking the lead in new infrastructure construction to hand over excellent “half year examination report card”

, ,

and

this year, under the influence of the epidemic situation, Chengdu’s rail transit construction has overcome the difficulties, overcome the huge pressure of “the highest construction intensity in history”, with the great determination and combat effectiveness of “grasping with both hands” and “two hands hard” in scientific epidemic prevention and resumption of work and production, and with the trend of “pacesetters” in the new infrastructure construction of the whole city, Chengdu has won “more than half of the time, too many tasks” in the “half year examination” “Half a” achievement!

and

at the same time, with engineering construction as an important support, drive the industrial chain enterprises to land in Chengdu, make the “cake” of rail industry circle bigger, and provide assistance for the economic development of Chengdu. In order to further reflect the supporting and basic role of public transport, implement the strategy of Chengdu Chongqing double city economic circle, develop Chengdu Dezhou Meizhou capital into the same city, and match the “cross policy” of “eastward advance, South expansion, West control, North transformation and medium optimization” of Chengdu, Chengdu rail group has accelerated the fourth phase of construction planning projects and intercity railway research.

and “guarantee opening” projects to overcome the impact of the epidemic situation on

and

, and ensure that seven lines will be “blowout” before the end of the year. 2020 is destined to be an extraordinary year for Chengdu Metro builders. It is estimated that 7 lines will be put into trial operation in 2020, including phase I and II of line 6, phase I of line 6, phase I of line 8, phase I of line 9, phase I of line 17, phase I of line 18 and phase II of line 18, including 113 stations (71 transfer stations), 9 vehicle bases and 12 main stations. Such construction intensity has set a record again. In particular, the highest speed of phase I and phase II of line 18 can reach up to 160 km / h, which is the first subway line to enter the city by express line in China, which can be described as “unprecedented”. Zhu Junping, vice chairman of Chengdu rail group and Secretary of the Party committee of Chengdu Rail Construction Management Co., Ltd., described the construction pressure this year. Under the pressure of such a large opening up, it also encountered a sudden epidemic, which can be described as “adding to the frost”. In the face of the double superposition of epidemic pressure and construction pressure,

and

still achieved “more than half of the time and half of the task” in the first half of the year. Why?

“just one word: dry!” His answer was extremely short, but loud. Looking at Zhu Junping’s circle of friends,

and

is more like reading a solid “work log”, which records all the nodes of resumption of work and production –

and

on February 6, the first working site obtained the notice of approval to resume work.

and

on February 13, all the seven work sites of the first four projects met the standards and resumed work.

and

on February 16, after a long pause, this is the most beautiful sound — the sonorous and powerful sound of crusher in Century City station is shown in the picture.

February 19, full fire! In a short period of 13 days, 3733 management personnel and 3426 front-line workers were in place. A total of 355 work sites (382 in total) have obtained the notice of approval to resume work issued by the Municipal Bureau of housing and urban rural development, and the rate of obtaining evidence for returning to work has reached 93% — this is the speed of Chengdu!

and

resumed work and production on February 28. We are serious. As of yesterday, there were 6586 managers and 17250 workers at 382 sites of Chengdu rail transit.

and

on March 5, two days later, all the 33000 labor force will arrive.

and

on March 17, as of 17:00 yesterday, the number of on-site management personnel + workers = 50683.

,

on May 1, more than 60000 builders fight in more than 400 construction sites every day! The answer is always on the spot There are too many stories behind the figures of

and

which reflect the “rail speed”. The

and

subway projects have many people, and personnel are an important factor to ensure the construction progress. In order to return to work as soon as possible, according to the construction progress on site, Chengdu rail group, with the help of “spring breeze action” and the principle of “sub bid section, sub process and step by step”, reasonably arranged the labor personnel to return to work in batches, orderly and staggered peak. The first batch of returned workers are those living in Chengdu, who are required to apply for health status declaration card and five color card as required by Chengdu; the second batch is personnel outside Chengdu in Sichuan Province; and the third batch is personnel from non epidemic areas outside Sichuan Province. Self driving and car chartering are adopted for the return journey, and “home site” one-stop scheme is adopted to ensure the safety of epidemic prevention and control.

period is not without difficulties. “We have always believed that there are more ways than difficulties.” Shi Yaxin, chief engineer of Chengdu rail transit group and chairman of Chengdu Rail Construction Management Co., Ltd., said that the municipal, district (city) and county governments at all levels and relevant functional departments gave full support; the construction general contractor went all out regardless of conditions. Shortage of materials – in addition to the increase in the city, all resources are used for procurement; the construction period is tight – the operation time is extended, and the original 12-13 hours of operation time is adjusted to 24 hours

and

under the premise of grasping the epidemic prevention and control, the 382 construction sites of Chengdu Metro have completed the resumption of work in only one month. After that, he added more manpower and material resources. He worked 24 hours a day to exchange time with space. With unconventional fighting spirit, he wrote a magnificent and powerful “Symphony” of construction, ensuring the smooth completion of the half year goal.

with the continuous extension of Chengdu rail transit lines, Chengdu rail industry circle is also developing. Take CRRC Chengdu Locomotive and rolling stock Co., Ltd. as an example, the company has provided vehicles for Chengdu Metro Line 7, line 10, line 6, line 17 and line 18.

focus on rail transit vehicles, traction and signal based on subway constructionIn key system fields such as integrated monitoring, Chengdu rail group has actively introduced a number of projects with good efficiency, strong driving force and core technology, and has continuously guided and promoted more than 30 enterprises including CRRC Sifang, CRRC Changke, Casco, Beijing traffic control and ALSTOM to set up R & D and production bases in Chengdu. ” Chengdu Rail Industry Investment Co., Ltd. said.

“Chengdu rail transit enterprises started from 34 in 2015, and have now grown to 279.” According to the person in charge, the city’s four construction plans have been approved by the national development and Reform Commission, with a total mileage of 692km and a total investment of 463.3 billion yuan. “The civil engineering market is not only the big head, but also the basis and forerunner of the follow-up market – without such a large construction scale, there would be no such a large market; without such a fast opening speed, there would be no rapid development of rail industry chain and ecosystem.” Zhu Junping, vice chairman of Chengdu rail group and Secretary of the Party committee of Chengdu Rail Construction Management Co., Ltd., said.

have brought huge market space. It is estimated that by 2035, the market demand for large-scale UN wheeling repair of 8000-10000 vehicles will be formed in Chengdu. At present, the city’s rail transit has formed an annual production capacity of more than 2000 vehicles, with the manufacturing capacity and maintenance capacity of Metro and tram. Among them, type B vehicles of line 3 and line 4 and type a vehicles of lines 5, 8 and 9 have been localized in Tianfu Intelligent Manufacturing Industrial Park, with the annual output of 800 Metro or trams and maintenance capacity of 300 vehicles; type a aluminum alloy trains of lines 6, 7, 10, 17, 18 and 19 have been localized in Xindu modern transportation industry functional area. In terms of the national railway market, a series of major projects, such as Chengdu Chongqing middle line high-speed railway, Sichuan Tibet railway, Chengdu NANDA Wanzhou high-speed railway, mountain rail transit, and Chengdu Gejie high-speed railway, were implemented during the 13th and 14th five-year plan periods, and the development space of rail transit industry is huge.

is planned to build 8 lines with a total length of 176.6km. The first batch of 5 lines, including the third phase of line 10, phase I of line 13, phase II of line 17, phase III of line 18 and phase II of line 19, with a total of 119 km, have been started construction at the end of 2019. ” Pointing to the road map in hand, Jiang Kui song, general manager and Deputy Secretary of the Party committee of Chengdu Rail Construction Management Co., Ltd., introduced.

and

on May 19, this year, the first shield machine of phase II project of line 19 was successfully launched from Tianfu new station, marking that the fourth phase construction planning of Chengdu rail transit has officially entered the shield construction stage. As another airport line in our city, the second phase of line 19 can merge into line 18 at Tianfu new station, realizing direct connection between Shuangliu International Airport and Tianfu International Airport, which is also the first parallel operation mode of Chengdu Metro. Passengers can go directly to Tianfu International Airport through line 18 without changing trains at Tianfu new station on line 19. The third phase of

and

line 10 is an extension of line 10 to the city center, starting from people’s Park Station and ending at taipingyuan station of line 10 (completed and operated). “The third phase project of line 10 forms many transfer points with the urban rail transit network, which reduces the transfer times and the transfer pressure of a single transfer station; it can take into account the functions of rapid travel and airport line in the central urban area, and clearly divide the functional levels with the urban rail transit network, so as to form the urban express network from the perspective of the whole city; strengthen and meet the requirements of the central urban area and the dual functions The traffic demand in the peripheral areas of Liuzhou and Xinjin is the need to realize the integration of comprehensive transportation, networking and optimization of traffic structure The person in charge of the project pointed to the circuit diagram for further introduction. It is reported that at present, four stations and the distribution lines behind the line have been closed, and preliminary work such as green relocation and pipeline relocation is being carried out.

Up to now, 64 stations and 4 field sections of the first batch of construction projects in the fourth phase of construction planning have been enclosed; among them, 35 stations have started construction of retaining piles, 17 stations have started earth excavation construction, and 8 stations have entered the construction stage of main structure; 4 field sections have been leveled and three temporary constructions have been carried out, 2 have been for retaining pile construction, 1 for earthwork construction and 1 for structural construction Work. The preparation work before entering the site of the second batch of start-up projects is normally carried out. Among them, the first shield machine of the second phase of line 19 was launched on May 22, with a total of 349 meters. At present, seven shield machines have been put into the well. The second batch of 3 lines of
