Automatic concrete vibrating method for pier with limited top
The invention relates to the technical field of a method or equipment special for erecting or assembling a bridge, and discloses an automatic concrete vibrating method for a pier with a limited top, in the method, whether the concrete liquid level meets the requirement or not is automatically judged through a specially-designed liquid level meter, so that whether the concrete liquid level reaches a marked position or not does not need to be observed, and the working efficiency is improved. Excessive pouring is avoided; the optimal vibrating duration of concrete is measured in a ground experiment, then a vibrating rod is put into a pouring bin before vibrating, after the concrete is poured in place, a PLC is used for automatically starting vibrating, after vibrating is conducted for the set duration, the PLC is automatically stopped, the vibrating rod is pulled out along a guide cylinder through an electric capstan, and therefore concrete segregation caused by excessive vibrating is avoided; the vibrating rod is pulled out one by one by utilizing the stepping motor instead of being pulled out quickly by one breath, so that the time for filling the cavity after the vibrating rod is pulled out is provided, and the compactness and uniformity of the concrete after being poured are ensured.
本发明涉及专用于架设或装配桥梁的方法或设备技术领域，公开了一种用于顶部受限的桥墩的混凝土自动振捣方法，本发明中，通过用专门设计的液位计自动判断混凝土液位是否达到要求，从而无需观察混凝土液位是否抵达标记位置，避免了过量浇筑；通过在地面实验中测出混凝土的最佳振捣时长，然后把振捣棒在振捣前放入浇筑仓，混凝土浇筑到位后，用PLC控制器自动开启振捣，振捣到设定的时长后，自动停止并通过电动绞盘沿着引导筒拔出振捣棒，从而避免了振捣过度导致混凝土离析；通过利用步进电机一下一下把振捣棒拔出来，而不是一口气快速拔出振捣棒，从而提供了让混凝土填充振捣棒拔出后的空腔的时间，确保混凝土浇筑后致密而均匀。
