Construction method for inserting super-long steel stranded wires before pouring of bridge body

The invention discloses a construction method for inserting super-long steel stranded wires before pouring of a bridge body. The method comprises the following working flows of: fixing a corrugated pipe positioning framework on a beam supporting framework; processing a corrugated pipe, reserving a half pipe skylight on the corrugated pipe, and installing the corrugated pipe; cutting the steel stranded wires, and bundling the steel stranded wires in groups; gradually inserting the bundled steel stranded wires under the traction of a windlass; and covering the corrugated pipe skylight. The method solves the problems that the corrugated pipe has high flexibility and is easily broken and blocked, the prestressed steel stranded wires are positioned inaccurately and the like when the steel stranded wires are inserted before the concrete is poured; the construction method is simple, and low in manpower equipment input; the steel stranded wire bundle which consists of 17 steel stranded wires with the length of 73 met
