Abstract:
Provided are a prefabricated combined assembly-type anti-floating tensile prestressed anchor rod member and a construction method therefor. The prefabricated combined assembly-type anti-floating tensile prestressed anchor rod member comprises an unbonded steel bar or a main reinforcing steel bar, a hollow tubular column for a prestressed anchor rod, and nuts for anchor locking. The unbonded steel bar or the main reinforcing steel bar is inserted into the tubular column; and with the prefabricated hollow tubular column as a support, two ends of the steel bar are tensioned, a prestressing force is applied thereto, and then locked at two ends of the tubular column by means of the nuts, so as to form a prefabricated prestressed anchor rod member. The main reinforcing steel bar is high-strength finish-rolled screw-thread steel, the surface of the main reinforcing steel bar is provided with an anti-corrosion grease layer, and a sleeve is provided outside the anti-corrosion grease layer, so as to form a prefabricated prestressed unbonded steel bar.
