Advantages of high strength bolts can be summarized as follows:
High strength and toughness: High strength bolts undergo special treatment, possessing characteristics such as high strength and toughness, making them particularly suitable for hard formations like rock. This enables them to withstand large tensile and compressive forces, ensuring the stability and safety of engineering projects.
Long service life: Due to their high strength and corrosion resistance, high strength bolts have a relatively long service life, ensuring better quality and stability of engineering projects.
Convenient construction: Compared to traditional foundation support methods, the construction period of high strength bolts is relatively short, which can shorten the overall construction period of the project, improving project progress and efficiency.
High prestressing capacity: For specific types such as left-hand high-strength anchor rods, they have a large prestressing capacity and good self-locking effect, allowing for high prestressing to enhance support effectiveness.
High anchoring force: In some types of anchor rods, due to special designs such as left-hand high-strength anchor rods, their anchoring force is higher than that of ordinary anchor rods, improving the reliability of support.
Disadvantages of high strength bolts can be summarized as follows:
Strong rigidity: High strength bolts have strong rigidity and are not easily bent or adjusted, requiring special care during installation to avoid affecting the overall structure.
Risk of rod deformation: In tunnels with high ground pressure and strong dynamic pressure effects, high strength bolts may experience rod deformation, which may lead to instability of the support structure when severe.
Challenges in design and construction: The current design of anchor rod support is not yet perfect, and sometimes the application of engineering analog methods may result in insufficiently scientific support parameters and forms, increasing support costs. At the same time, construction personnel may have insufficient understanding of the theoretical system of anchor rod support, making it difficult to meet construction design requirements.
Lack of impact toughness: In high strength bolts, if there are many internal micro defects, it may lead to insufficient impact toughness, resulting in brittle fracture.
In summary, high strength bolts have advantages such as high strength, long service life, and convenient construction, but attention should also be paid to their rigidity, risk of rod deformation, and challenges in design and construction. Additionally, addressing potential issues of insufficient impact toughness requires strict control during material selection and processing.
