Self-drilling anchor bolt used for soft geological slope support
Time:2020-10-29From:sinorock View:
With the development of urban underground space, there are more and more deep foundation projects. Traditional slope anchoring method cannot meet the requirements of slope stability when it meets complicated geological conditions, especially soft soil, sand and pebble stratum. And the porosity is low in the construction, which causes great pressure for grouting anchoring in the later period and greatly increases the construction cost.One of the Jinan Railway Bureau residential building project design life of 50 years, six degrees of seismic fortification. The structure is the shear wall structure, with the pile-raft foundation, and the base deep is 10.65 meters. 4-7 meters below the ground on the north side of the project is soft soil with an average thickness of 1.9 meters.
As a new anchoring technology, self drilling anchor bolt can adapt to various complicated geological conditions and environments, especially in soft soil. Self drilling anchor bolt is composed of hollow bar, bit, nut, plate, coupler and centralizer. It has the following advantages:
- High construction efficiency
- Applicable to soft soil layer
- Strong adaptability
- Good anchoring effect
In general, self drilling anchor bolt not only increases the construction length but also avoids the inefficiency of hole formation in the pre-hole process, which makes the anchor bolt and the soil more closely combined. Self drilling anchor bolt has excellent advantages in construction procedure, drilling quality and efficiency, which brings high efficiency, good economic and social benefits for engineering construction. It fully shows that self drilling anchor bolt has wide applicability in soft geological slope support.

- 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.
