Editor's note:

  Every Chinese who lives hard is the most beautiful struggler.

It is precisely because of the hundreds of millions of strugglers that China is today.

Ten years, pay tribute to every one of you who have struggled.

Let us work hard together for the new era, and never slack in the future.

  [Explanation] Han Qing, who was born in 1989, has worked hard to promote "new technology, new structure, new material, and new equipment" in the process of technical management for nearly ten years since he joined the work in 2013. Enthusiasm for progress.

After years of hard work, it has accumulated rich experience in shield tunneling construction technology and management, and has gradually grown into the technical backbone of the project.

On May 8, as usual, Han Qing came to the construction site of Hefei Metro Line 8, which is more than ten meters underground, to conduct a construction safety inspection.

  [Same period] Han Qing, Chief Engineer of the Shield Tunneling Branch of the Fourth Company of China Railway No. , Equipment hoisting, such as shield machine hoisting, gantry crane installation and dismantling equipment installation, including daily (equipment) maintenance and the like.

  [Explanation] According to Han Qing, the shield machine has a history of nearly 200 years, but before 2008, China's shield machine basically relied on imports, ranging from tens of millions to hundreds of millions, and the core The hardware, software, technology... are all in the hands of others. Every time the machine needs to be repaired, experts from abroad must be hired. Not to mention the high price, it also delays the construction progress.

  [Same period] Han Qing, Chief Engineer of the Shield Tunneling Branch of the Fourth Company of China Railway No. At that time, there were few people in China who could operate the system proficiently. At that time, from commissioning to work, they all sent special personnel from the manufacturer, that is, Japan, to guide them, but the later maintenance was very troublesome, that is to say Accessories are all imported, and now the guidance system is all made in China, and we have mastered the core technology, we can operate it ourselves, and there is no problem with maintenance.

  [Explanation] The shield machine is an indispensable key equipment for the efficient construction of high-speed rail tunnels and urban subways. With the continuous advancement of science and technology, China can independently design and manufacture shield machines, which has changed the long-term dependence on foreign countries and is no longer controlled by others.

Today, domestic shield machines not only meet domestic needs, but are also exported overseas in large quantities.

  [Same period] Han Qing, Chief Engineer of the Shield Branch of the Fourth Company of China Railway No. , Construction technology, construction quality, safety, progress, etc. have all been significantly improved, providing a sharp weapon for China's development and urban infrastructure.

  [Explanation] As an engineer, innovation and efficiency creation have always been a topic that Han Qing attaches great importance to.

At present, his company has 45 young technicians, and established a youth QC team in 2017, with a total of 12 people, all born in the "90s".

Under the leadership of Han Qing, the Youth QC Research Group obtained 1 national invention patent, 1 utility model patent, and published 2 papers.

  [Same period] Han Qing, Chief Engineer of the Shield Branch of the Fourth Company of China Railway Fourth Bureau, as a builder of the younger generation, saw the completed high-speed rail shuttle in the tunnel, and the urban subway facilitated the travel of citizens.

I think technological innovation has injected vitality into the development of society.

In our work, we must inherit the glorious tradition of the older generation of builders, maintain full enthusiasm for work at all times, and contribute our own strength to social development.
