Application of Glass Fiber Reinforced Bar Anchor in Foundation Pit Engineering

The application of glass fiber reinforced bar as anchor rod body in foundation pit engineering is introduced through engineering examples. The use of glass fiber reinforced bar instead of ordinary reinforced anchor rod or steel strand anchor cable effectively solves the problem that the rigid structure cannot go out of the red line of land and become a permanent ground barrier. Although the tensile strength of glass fiber reinforced bar is higher than that of ordinary steel bar, there are still some problems in the technical links such as the connection of bar body and the tension of glass fiber reinforced bar anchor, resulting in the tensile performance of fiberglass reinforcement can not be brought into full play. The fully bonded glass fiber anchor is directly cast into the crown beam (waist beam) without prestress, which avoids the disadvantage of low tensile force of the anchor due to the glass fiber connection. With the special connector at the end of glass fiber reinforced bar converted to steel strand, the tensioning of glass fiber reinforced bar anchor bar can be realized.
