The official website of Shanghai Songjiang Shock Absorber Group Co., Ltd. introduces the contract information of rubber bellows expansion for Qingdao Metro Line 8. Songjiang Group provides rubber soft connections for many domestic subway projects, mainly used for circulating pump systems, which play a role in shock absorption and noise reduction.Qingdao Metro orders rubber bellows expasnion for use in water heater pipelines. The high-temperature resistant rubber soft joints produced by our factory use EPDM rubber with a long service life.

Metro Line 8 starts from Jiaozhou North Station in Jiaozhou City, passes through Hongdao Economic Zone, Licang District, and Shibei District, and ends at May Fourth Square in Shinan District. The total length of the line is about 60.74 kilometers, with a total of 15 stations and a designed maximum speed of 120 kilometers per hour. The total investment of the project is about 32.151 billion yuan, of which environmental protection investment is about 160 million yuan. The project is planned to commence by the end of this year and be completed by 2021.
It is understood that the section between Qingdaobei railway station and Dayang Railway Station, where Metro Line 8 passes through the sea area of Jiaozhou Bay, is located at the bottom of the mouth of Hongdao East Bay in the northeast of Jiaozhou Bay. The section is 7.926 kilometers long, the sea area section is 5.4 kilometers long, and the rest is land section.

This section is an important node project of Metro Line 8 and the second sea crossing tunnel in the city after the sea crossing tunnel of Metro Line 1. The section is laid underground along Aodongnan Road from Hongdao Dayang Station, passing through Jiaozhou Bay on the east side of the toll station of Hongdao Expressway, to the reclamation project on the east bank of Jiaozhou Bay, along the planned green space, and to Qingdaobei railway station. Dayang Station is a two-layer island station, and Qingdaobei railway station is an island station. The construction has been completed and the interface conditions of Line 8 section have been reserved. Connecting the new airport and Hongdao Station, Metro Line 8 will pass through two major transportation hubs, namely Jiaodong International Airport and Hongdao Station.

At present, the Jiaodong International Airport Rail Transit Construction Project has been launched, which includes the construction of Jiaodong Airport Station and tunnel sections on Metro Line 8, Jiaodong Airport Station and related tunnel sections on the urban express line. At that time, the project will become the first zero transfer comprehensive transportation center in China that integrates high-speed rail and subway. It is located in the core area of the airport, adjacent to the airport terminal, including two major parts: the parking building and the transportation transfer center. The total construction area is about 200000 square meters, of which the parking building has a construction area of about 150000 square meters, mainly used for passenger parking vehicles; The transportation transfer center has a construction area of approximately 50000 square meters, and its main function is to connect with high-speed railways and subways, as well as provide public transportation, commercial services, and other functions.
