rolling tube technique

Using self-boring grouted rock external screw bolt to build geotechnical anchor, is the key technique by which resolve the difficulty of the construction in complex geologic circumstances. And external screw steel tube rolling is the key equipment to manufacture finish rolling external screw steel tube.

使用自钻注浆式外螺纹锚杆进行岩土锚固施工，是解决复杂地质条件施工难题的关键技术，而外螺纹钢管轧机则是生产精轧外螺纹钢管的关键设备。
