多年来，水泥混凝土路面施工中都采用长板振动梁的传统工艺（即：圆管形、槽形），振动器放在中间位置，一般跨径为4．7m和3．7m，由于水泥路面浇筑两边立模都采用角钢和槽钢，两边钢模与振动梁接触断面小，再加上硬碰硬，而振动器又设在中间位置，振幅不均匀，只 Over the years, the traditional process of long-plate vibration beams (ie, round pipe shape and slot shape) has been adopted in the construction of cement concrete pavement. The vibrator is placed in the middle position with the general span of 4.7m and 3.7m. Since the cement pavement Pouring both sides of the legislation are used angle and channel, on both sides of the steel mold and the vibration beam contact cross section is small, plus hard touch, and the vibrator is located in the middle position, uneven amplitude, only
