On the morning of August 7, a super large diameter shield machine with a diameter of 15.01 meters and a length of 130 meters was launched in Guangzhou. The shield machine will be used in the construction of the su'e channel project of Shantou cross sea tunnel of China Railway Tunnel bureau group

according to the technicians of China Railway Tunnel bureau group, Shantou su'e channel cross sea tunnel project is the first subsea tunnel located in the area with 8-degree earthquake intensity in China. At the same time, there are a large number of high-strength boulders and 182 meter long bedrock protrusions within the tunnel, which are characterized by complex geology, high construction difficulty and high safety risk level. The total length of the tunnel is 6680 meters, the length of the shield section is 3047.5 meters, and the design speed is 60 kilometers per hour. At present, it is the most difficult large-diameter shield subsea tunnel in China. After the completion of the tunnel with a diameter of 15.01 meters, the inner diameter of the tunnel is 13.3 meters, which can reach the two-way six lane traffic capacity

the shield machine has the function of ultrasonic geological detection, and can do color Doppler ultrasound like doctors. The finite element method adopted in this paper will still accelerate the industry through spontaneous supply contraction in 2016. The traditional capacity clearing method is more in line with the actual sample to check and explore the geological conditions in front of the tunnel. The shield machine has also been designed with the function of changing the cutter under normal pressure, and is equipped with a mouth piece installation system with synchronous construction function. The offline of this super large diameter shield machine will lead China's cross sea tunnel shield construction technology into a new stage

after the tunnel is completed and opened to traffic, it will open up a new channel across the sea between the north and south sides of Shantou, which is of great significance to enhance the urban agglomeration and radiation function of Shantou and promote the economic and social development of Shantou.
