R38L Self-Drilling Anchor Bolt for Constructional Engineering
As a tension member deep in the stratum, one end of the bolt is connected with the engineering structure, and the other end is deep in the stratum. The whole bolt is divided into a free section and an anchoring section. The free section transmits tension from the bolt head to the anchor solid, while the anchoring section binds the prestressed reinforcement to the soil layer, increasing friction and bearing capacity.
