Unbonded prestressed construction anchor rod
The invention discloses an unbonded prestressed construction anchor rod and belongs to the technical field of civil engineering construction. The unbonded prestressed construction anchor rod comprises a guiding head, an anchor rod outer steel tube, a main anchor rod body, an anchor pad and an anchor part and is characterized in that the main anchor rod body is made of a prestressed steel bar, a rebar or a steel cable, and the anchor rod outer steel tube is flexibly connected with the guiding head and located on the outer side of the main anchor rod body. The unbonded prestressed construction anchor rod has the beneficial effects that as that the main anchor rod body can be made of the prestressed steel bar, the rebar or the steel cable, the stress of the main anchor rod body can be adjusted continuously during construction, and process control can be achieved; the anchor rod outer steel tube is flexibly connected with the guiding head, located on the outer side of the main anchor rod body and used for foundation pit engineering maintenance, and therefore later-period backfill can be recycled in a layered or segmented mode. The unbonded prestressed construction anchor rod is simple in structure and convenient to implement.
