Pipe Pile

- Jun 30, 2017 -

In the late 60, the Ministry of Railways Fengtai Bridge factory began to produce the prestressed concrete pipe pile (PC pipe pile), which was mainly used in the foundation construction of railway bridge engineering, and the post tensioned prestressed concrete pipe pile was developed and produced in 70. Since the 70 's, especially in Shanghai Baoshan Iron and steel plant construction, a large number of use of Japanese steel pipe pile, not only high cost, poor durability. In order to meet the needs of the development of Port Construction, in 1987, the Ministry of Communications three-board from Japan to introduce a full set of prestressed high-strength concrete pipe pile (PHC pipe pile) production line, The main specification of PHC tubular pile is vertebral 600mm vertebra 1000mm. In the late 80, Ningbo Zhedong Cement Products Co., Ltd. cooperated with the research institutes, in view of the characteristics of the soft geology in the coastal area of our country, through the transformation of PC pipe pile, the paper developed the prestressed concrete thin-walled tubular pile (PTC pipe pile), and the main specification of PTC pipe pile is 300mm vertebral 600mm. 1989 1992 Years, The former National Building Materials Bureau Xuzhou Concrete Cement Products Research Institute and Fanyu Bridge Fung Cement Products Co., Ltd. According to the actual situation in China, through the introduction of pipe pile production line digestion and absorption, the independent development of domestic prestressed high-strength concrete pipe Pile, 1993 the results of the original Ministry of construction in the National Key promotion project
