Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, November 16, according to the China Railway Construction Group Co., Ltd., the domestic largest diameter pipe jacking machine "Tiejun", jointly built by China Railway Construction heavy Industry and the eighth Bureau of China Construction, was successfully off the line in the first Industrial Park of Railway Construction heavy Industry a few days ago and will soon be put into construction.

▲ map learned from CTOnews.com of the State-owned assets Supervision and Administration Commission of the State Council that the geological conditions of the project applied by the "Tiejun" are complex, which need to cross rivers, ancient city walls, municipal roads, railways, and involve the relocation of many 220kV high-voltage lines, passing through full-section hard strata, upper and lower hard strata, clay strata, and so on. The project adopts three parallel pipe corridors with different cross sections to be excavated at the same time, in which the pipe jacking construction is adopted in the cultural relic protection area and the main road section, and the outer diameter of the pipe jacking section is 5.4 meters, which is the largest round section pipe jacking in similar projects in the country. this puts forward higher requirements for the design of pipe jacking machine.

According to the characteristics of the project, Railway Construction heavy Industry has jointly developed the domestic largest diameter pipe jacking machine "Tiejun" with the eighth Bureau of China Construction, through targeted design and a number of intelligent auxiliary systems to ensure that the pipe jacking machine is safe, environmentally friendly and efficient to complete the construction of super-large cross-section pipe gallery.

The successful offline of the "Iron Army" marks another breakthrough of Railway Construction heavy Industry in the field of domestic high-end underground engineering equipment pipe jacking, and is of great significance to further improve the level of mechanization and intelligence of pipe network construction.
