Title: Zhaofeng Wang: Innovator in Tunnel Support Technology
Introduction
Zhaofeng Wang is a notable inventor based in Yunnan, China. He has made significant contributions to the field of tunnel engineering, particularly in the area of support devices for high-stress tunnels. His innovative approach addresses the challenges posed by cataclastic rock masses, which are prone to large deformations.
Latest Patents
Wang holds a patent for a "Zonal bolt-grouting support device and method for cataclastic rock mass large deformation of high-stress tunnel." This invention outlines a method that includes drilling holes in the surrounding rock of a tunnel after excavation, installing high-strength prestressed anchor members, and applying a preload to anchor bolts. The method also involves zonally grouting the surrounding rock after stress adjustment. The components of the high-strength prestressed anchor member include an anchor bolt, an expansion anchor agent, a decoupling material, a grouting device, and a reverse anti-skid device. The grouting device is designed with a shallow grouting steel pipe, a deep grouting steel pipe, and a grouting stop valve, arranged side by side with the anchor bolt in a drill hole. This technical proposal effectively inhibits the large deformation of cataclastic rock masses.
