采用振动水压法生产钢筋混凝土压力管时,混凝土拌合物作径向移动推动环向筋,使之受拉。对于这种使钢筋获得应力的方法,必须采用低流动性的拌合物,灌注入模时需要强烈的振动,从而有相当高的振动噪音。 Vibration hydraulic pressure production of reinforced concrete pressure pipe, the concrete mixture for radial movement to promote the ring tendons, so that the tension. For this method of stressing the steel bar, a low-flow mixture must be used, which requires strong vibrations during injection into the mold, resulting in considerable vibrational noise.
