Slope Engineering: Ensuring Stability and Safety

Time:2024-04-12From:This Site

The slope is the natural or man-made inclination of the earth's surface, referring to all geological bodies on the earth's surface with inclination to the airside of the ground, are the geomorphic landscape widely distributed on the earth's surface, playing an important role in shaping the landscape. While slopes are crucial for the environment and human development, they can also pose risks due to slope failures and landslides. This has led to slope engineering, a multidisciplinary field, that focuses on assessing, managing, and mitigating the risks associated with slopes.

Advantages of self drilling hollow anchor bolts used as soil nails

Time:2024-03-20From:This Site

Soil nailing is currently an important technology for reinforce slopes such as mountains, dams and building foundations. However, the traditional technology is to drill holes first, and then anchor bars are embedded in the holes and grouted and fixed. The construction process not only faces problems of high construction difficulty, low work efficiency, and high cost, but also faces the problem of poor connection stability between soil nails and geological structures. In recent years, self drilling hollow anchor bolts have been widely used in soil nail support due to their simple construction t
