The first station of Qingdao Metro Line 15 started, and strive to enter the physical construction in the whole year

Qingdao Daily/Guanhai News, September 6th. Today, the staff of the quality and safety supervision station of the municipal public engineering engineering work on the quality and safety supervision station of the municipal public engineering work on the construction preparations of the three links, the enclosure, the eleven -brand five maps, the power of the electricity equipment, and the smart construction site system And after a detailed verification of the safety, quality system construction, and responsibility system, the Qingdao Metro Line 15 Tianshan Second Road Station passed the project acceptance and became the first station to start construction.

Tianshan Second Road Station is located in Tongji New District of Jimo District. The station is the underground two -story "prefabricated+paddling" station. The station has a length of 330 meters, a standard section width of 20.5 meters, and a platform width of 11 meters. There are 4 entrances and 2 security exports.

Tianshan Second Road Station, as the only assembly station on Line 15, undertakes the double starting task of Tianshan One Road -Tianshan Second Road Station TBM interval and the entry and exit shield interval of the Rhonghogan vehicle section.

The subway premium station is a new form of prefabricated buildings. It concentrates the production of reinforced steel and concrete in the factory into prefabricated components in the factory, and then transports it to the construction site. It can make the construction production of the construction structure realization. Compared with the structure of traditional paddling subway station, prefabricated stations have the advantages of high efficiency, controllable quality, energy saving and environmental protection.

The anchor to build a world -class subway target and promote the implementation of advanced technology and innovation concepts. During the construction process, Line 15 responded to the "beautiful China" ecological civilization construction goal, and the principle of "smart ecology, green energy saving" runs through the entire process of engineering design.

By flexibly optimizing the driving organization, realize green low -carbon performance -Line 15 will be the first urban rail transit line in the province to adopt the fast and slow car operating organization mode; on the basis of dark digging of the pillarless pillar of Line 1, creating Mingming digging The concept of the pillar -free station has a total of 10 Ming dug -pillar -free stations; combined with the experience of flood control experience in the early stage of operating lines, setting a water puddle at the barrier -free elevator to effectively avoid the use of barrier -free elevators due to leakage. Carbon high -quality concrete, improve material performance, improve construction quality, simplify decoration and decoration; study prefabricated ground -type assembly station construction method, while prefabrication, realize the combination of walls with the wall, reduce the area of ​​grounding, improve construction work, effective Solve the problem of leakage.

The first phase of Line 15 is about 30.8 kilometers, with 17 stations, 6 transfer stations, starts at Xiawangbu Station, and ends at Sifang Factory Station. The line connects the key development groups such as Li Cang's core district, large residential area along Heilongjiang Road, Chengyang Center, Jimo Vocational Education City, Qingdao Rail Transit Industry Demonstration Zone and other key development groups. After completion The efficiency of travel has promoted the integrated development of Qingdao's main urban area.

According to Xing Jianjun, director of the engineering department of the Second Construction Branch of Qingdao Metro Group Co., Ltd., currently 60%of the green relocation of Line 15, 5%of the control of the control, the beginning of the Fujinbu Station (Xiawangu Station to Fujin Road Station) Fajing and Tianshan Second Road Station have begun to enter the physical construction. The second Construction Branch will take "innovation" as the lead, "safe, high -quality, high efficiency, green, wisdom, harmony" as the goal, and move towards the goal of "building a world -class subway". Line 15 work in the early stage of work and comprehensively enter the physical stage construction. (Qingdao Daily/Guanhai Journalist Zhou Jianliang)
