T52 Self Drilling Anchor Bolt
T52 Self Drilling Anchor Bolt is a type of Self Drilling Anchors Bolts T Thread. T52 Self Drilling Anchor Bolt adopts T-thread design, with a concave groove on the top of the thread teeth, forming a double top line structure, and a flat surface connection. This design enhances the adhesion between the anchor body and the slurry and improves the anchoring effect.
Description
T52 Self Drilling Anchor Bolt is a type of Self Drilling Anchors Bolts T Thread.
Characteristics of T52 Self Drilling Anchor Bolt:
1. Structural characteristics
T52 Self Drilling Anchor Bolt adopts T-thread design, with a concave groove on the top of the thread teeth, forming a double top line structure, and the surface is flat connection. This design enhances the adhesion between the anchor body and the slurry and improves the anchoring effect.
2. Construction advantages
T52 Self Drilling Anchor Bolt integrates drilling, grouting, and anchoring functions. Construction can be completed without casing. It is suitable for formations that are prone to collapse and difficult to form holes. It can solve the common surrounding rock instability problems in tunnel and slope engineering.
3. Mechanical properties
The tensile strength and yield strength parameters of the T52 Self Drilling Anchor Bolt rod body are optimized according to geological conditions. When matching the drill bit, it is necessary to combine the specific project requirements to ensure that the bearing capacity meets the engineering standards.
Application of the T52 Self-Drilling Anchor Bolt:
T52 Self Drilling Anchor Bolt is mainly used in geotechnical engineering such as tunnel surrounding rock reinforcement and slope support. It is especially suitable for areas with weak surrounding rock or broken rock layers. It can effectively control surrounding rock deformation and ensure construction safety.
