In Changsha No.1 Industrial Park of China Railway Construction Heavy Industry Group,The huge Shield Machine production workshop is also a laboratory.,Zhang Shuaikun's team is stepping up the demonstration of new technology experiments.。

Zhang Shuaikun:On the Shield Machine,We have a very new technology called synchronous push technology.。Shield machine in the process of forward construction,The annular prefabricate structural member can be assemble synchronously,And greatly improve that construction efficiency.。

Continuous improvement and progress of domestic shield machine,Such as“Underground dragon”Through the mountains,Drilling rivers and seas。But 15 years ago,,When Zhang Shuaikun graduated from university and entered the industry,China does not have its own shield machine.,Only shield machines imported from abroad can be used in construction.。Zhang Shuaikun made up his mind,We must make China's own shield machine.。After two years of work, he applied voluntarily.,Transferred from the management post to the construction site as a shield machine driver。In a dark, dank underground tunnel.,In order to understand the shield machine,Zhang Shuaikun often stays for 12 hours.,I have to study the drawings by myself after work.。

That's all,He participated in the successful application of the first domestic earth pressure shield machine in the construction of Changsha Metro Line 2.,Since then, he has presided over more than 60 key core technologies.,It has solved many world-class problems of shield machine construction in complex strata.。

Zhang Shuaikun:I am now less than 40 years old and have been exposed to more than a dozen projects with world-class impact.,This is due to our country's institutional advantage of concentrating on major affairs.。The state has invested heavily in infrastructure.,A lot of practical engineering experience,This is where we go abroad.。

At present,The shield machine of China Railway Construction Heavy Industries has been exported to Russia.、Turkey、Italy、South Korea and other countries and regions,Chinese shield machine,Technically, it is in the leading position in the world.。But Zhang Shuaikun did not stop.,He led the team.,Continue to a new goal.“Tunneling”。

Zhang Shuaikun:In the future, the shield machine will be multi-mode intelligent.,Develop in a bigger and more reliable direction,We need to develop more leading technologies to realize intelligent construction in the tunnel industry.,Even unmanned construction。
