What are the requirements for vibrating concrete with vibrators?
(4). The thickness of the stratified vibrations can not exceed 1.25 times the length of the rod, and when the concrete is vibrated on the upper layer, the head should be inserted into the next layer of concrete for 5cm deep so that the upper and lower layers are dissolved together to avoid seams
(3). Vibrating should be noted that vibration rods can not hit steel, stencils and embedded parts and buried pipeline.
(2). Plug-in vibrator should be noted that when the fast pull slowly pull, not because of the bar fast and left in the concrete hole.
The insertion point should be evenly arranged, the spacing can not exceed 1.5 times the radius of the vibrating rod, and the distance between the vibrating bar and the template is 0.7 times the radius of action.
