Self drilling rock bolt for stability of highway and people’s safety

Before the mid-1980s, China mainly has low-grade road, traffic is less, invest is little and the depth of digging is shallow, so it is unnecessary to focus on the protection technology of side slope.

For a long time, the protection technology of side slope in China is a weak link in road construction. Before the mid-1980s, China mainly has low-grade road, traffic is less, invest is little and the depth of digging is shallow, so it is unnecessary to focus on the protection technology of side slope. After the 1990s, construction of highway has entered a top-speed stage.

Without systematic research, mature experience and technology support, it has brought hidden danger, great loss and bad social effect, sometimes it even make the traffic and roadbed collapsed. This phenomenon has connected not only with the quality of materials, but also with the side slope protection system.

With the rapid development of highway construction in China, the side slope protection system constantly bring the highway department’s attention. It should be based on the condition of road’s grade, rainfall intensity, underwater, terrain, geology and materials of construction. To ensure the stability of highway and people’s safety, self drilling rock bolt for slope is widely used in recent years.

Recent years, the research of side slope protection system and reinforcement technology in highway has been focused by most people. The support effect of self drilling rock bolt has constantly strengthened and played a more and more important role.
