Manufacturing is the foundation of a country and a strong country.

The central region is an important modern equipment manufacturing and high-tech industrial base in China, and the General Secretary of the Supreme Leader is always concerned about the manufacturing development here. During his inspection in Zhengzhou, he emphasized that China manufacturing should be transformed into China creation, China speed should be transformed into China quality, and China products should be transformed into China brand.

The world’s first, China’s strongest, breaking through the blockade … Besides these "hard core" labels, what other amazing appearances are made in China? Recently, Xinhua News Agency reporters walked into the manufacturing enterprises in the central region and were pleasantly surprised by the "online celebrity potential" of the manufacturing industry. They also witnessed people’s hard efforts to promote the quality change, efficiency change and power change of the manufacturing industry.

Your impression of the tunnel construction scene may be noise, dust, and the smell of gunpowder mixed with blasting. In fact, in the shield machine of China Railway Engineering Equipment Group Co., Ltd. in Zhengzhou, workers are enjoying coffee while operating fast excavation.

Shield coffee originated from the Baicheng tunnel project of Menghua Railway. In 2018, China Railway Engineering Equipment Group Co., Ltd. tailored the world’s first horseshoe-shaped shield machine at that time-"Menghua".

Shield machine is a steel giant consisting of 100,000 parts, enjoying the reputation of "king of construction machinery". For a long time, only a few countries in the world have mastered the preparation technology. It was not until the 1990s that China bought back two sets for the first time.

"Shield machines are subject to people, which seriously affects the efficiency of China’s infrastructure." Li Guang, secretary of the Party Committee of the Design and Research Institute of China Railway Engineering Equipment Group Co., Ltd., said that in 2008, China developed and manufactured the first composite EPB shield machine with independent intellectual property rights-China Railway No.1, which broke through the blockade of foreign core technologies.

The following year, China Railway Engineering Equipment Group Co., Ltd. established the largest shield R&D and manufacturing base in Zhengzhou.

From the largest diameter hard rock shield machine in China, to the world’s super-large rectangular shield machine, and then to the world’s first horseshoe shield machine … China Railway Engineering Equipment Group Co., Ltd. continues to set a new record in the field of shield.

In 2012, the first shield machine of China Railway Engineering Equipment Group Co., Ltd. went abroad and was successfully applied in Malaysia. At present, the company’s products have covered 25 countries and regions such as France and Italy, and its production and sales volume have been the first in the world for four consecutive years.

"Through more than ten years of hard work, China’s shield machine has realized from’ running with’ to’ running with’, and we will strive to lead the development in the future." Yang Huayong, an academician of China Academy of Engineering, said.

[Reporter’s observation]

From being behind the world for a hundred years to being the first in the world in terms of production and sales, China’s shield machine has developed at an amazing speed, and the next step is to move towards the goal of from big to strong. A new chapter of shield technology spectrum, coffee fragrance in the depth of tunnel. With the rapid progress of China’s high-end equipment manufacturing industry, big countries are no longer blindly "showing their muscles", but starting to move towards the development direction of customization, low carbon and intelligence, which will bring more imagination space for industrial development.
