The invention discloses a large-section conductor tension stringing construction method, which is characterized by comprising the following steps of: 1, conduction preparation: carrying out a compression joint test on conductors and ground wires, arranging tension fields and pulling fields, and cleaning construction channels; 2, suspension of a tackle; 3, spanning construction; 4, tension payingoff, ground wire and conductor payingoff, and temporary anchors in real time; and 5, compression joint of the conductors, tightening of the conductors, sag observation, and conductor suspension, thus finishing the whole construction. The method is used to ensure that in-phase sub-conductors have same payingoff tensions, thus guaranteeing the stringing construction quality; and by using the method, the construction processes such as the suspension of the payingoff tackle, payingoff of the conductors and pulling ropes, payingoff of the conductors, tightening of the conductors, accessory installation and the like are optimized, thus effectively improving the construction efficiency of the tension payingoff; and the labor power and time wastes are decreased, the fewer devices are used, the floor space is small, and the social economical efficiency is higher.
