The present application aims to provide a kind of narrow space bridge cable push-pull tensioning method, comprising the following steps: A, two groups or more than jack are provided between working anchor and tool anchor, each group of jack is evenly arranged, so that when it pushes tool anchor, tool anchor is uniformly stressed;B, intelligent oil pump controls the oil pressure of each group of jack, so that it remains consistent, and simultaneously push tool anchor, and the steel strand is tensioned, when jack pushes to reach the stroke position, anchor nut of working anchor is locked;C, intelligent oil pump returns oil, and tool anchor returns initial position;D, repeat steps A-C, until the cable force reaches the design requirement.The present application aims to provide a kind of narrow space bridge cable push-pull tensioning method, which can well meet the steel strand tensioning demand in narrow space, and the tensioning process is stable, without damaging steel strand twist angle, to ensure tensioning effect.
