Bridge construction method for a workpiece and the continuous beam web grouting

For existing bridge bellows grouting problems in the continuous beam web, the present invention provides a continuous bridge girder and construction method of filling a workpiece for: a workpiece, comprising a bellows assembly of three or more metal bellows configuration . Through the connecting pipe adjacent two metal bellows are connected together. At the bottom of the bellows assembly radial sidewall at one end of the metal bellows is opened a hole and grouting hose connected with grouting. An exhaust port are opened at the top of each of the metal bellows and are connected to an exhaust pipe. The present invention provides a workpiece, such that the convenient construction, shorter duration, material saving, cost reduction. At the same time, but also improve the quality of grouting, reduce environmental pollution. The construction method is to all be done during construction of the assembly and the layout tool, can save duration, cost, and ensure continuous bridge overall mechanical strength of the beam web.
