A few days ago, a help call from the construction site of the Shenzhen Metro Tunnel hit the Zhuzhou Cemented Carbide Group Company's drilling tool project preparation team, saying that the tunnel shield tunneling machine under construction had been shut down and opened, and two sets of shield cutters were urgently needed. This year, the hard-shield knives have strengthened against the trend, and the output in the first quarter is close to the output of 11 months last year, which has become a highlight of the company.
Shield Tunnel Boring Machine is a special large-scale construction machinery for tunnelling. It is widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. As a key supporting tool for shield tunneling, the shield cutter has high quality requirements and has been monopolized by foreign manufacturers in the past. With China's 4 trillion yuan policy of expanding domestic demand, and the vigorous development of basic construction in various places, the shield market has gradually emerged. As early as 2004, Zhuhard Group aimed at this market blank, relying on the company's technical advantages and brand advantages in the field of cemented carbide, research projects, and began to develop shield cutters. After several years of hard work, it was obtained. Success, the initial realization of industrialization, and the long service life of its tools, can meet the needs of various geological conditions, has been welcomed by users. At present, it has successfully entered the construction of subway tunnels in important cities such as Guangzhou, Shenzhen, Chengdu, Nanjing and Shenyang.
