在砼振捣密实的过程中,插入砼中的内部振动器发生高频振动而产生压力波,并以脉冲的方式传至于周围的砼中。砼中的颗粒得到脉冲振动后就围绕着某一位置连续振动。砼中的内摩擦力和粘度随之减小,具有流动性重质液体的流动阻力减小,骨料靠自重而紧密排列,裹入其中的空气泡受到挤压作用而逸出至砼的表面,于是砼就振捣密实了。 In the process of compacting the vibration, the internal vibrator inserted into the crucible generates high-frequency vibration and generates a pressure wave, which is transmitted to the surrounding crucible in a pulsed manner. The particles in the crucible are pulsed and vibrate continuously around a certain point. The internal friction and viscosity in the crucible decrease accordingly, and the flow resistance of the heavy liquid with flow decreases, the aggregates are closely arranged by their own weight, and the air bubbles entrapped therein are squeezed to escape to the surface of the crucible. , so 砼 捣 捣 捣 compacted.
