Usage of concrete vibrator

When using plug-in vibrator, plug it in quickly and pull it out slowly. Insertion points should be evenly arranged, moved point by point, and carried out in sequence, without omission, so as to achieve uniform compaction. The moving distance is not more than 1.5 times the action radius of the vibrator (generally 300~400mm). On a layer of vibrating should be inserted into the lower concrete surface 50mm, in order to eliminate the seam between the two layers. The moving distance of the plate vibrator should ensure that the plate of the vibrator covers the edge of the vibrating part.

Before pouring, the formwork should be watered and moistened, and after removing sundries and accumulated water, the cleaning mouth of the wall and column formwork should be closed. The free fall height of concrete falling from the bucket mouth shall not exceed 2m, and measures must be taken to add string drums if it exceeds 2m.

Matters needing attention in using concrete vibrator

Before the concrete vibrator is operated, check whether the power phase line connection is correct. After electrifying, if the concrete vibrator does not vibrate, the end of the concrete vibrator is generally knocked to the ground. After the vibration makes a steady and powerful chirp, the vibration operation can be carried out. ?

When the concrete vibrator is working, it should be inserted vertically or obliquely into the concrete and can vibrate for a certain period of time. When vibrating, the concrete vibrator should twitch up and down. In the case of layered casting on components or buildings, when vibrating one layer at a time, the concrete vibrator should be inserted into the vibrated layer to eliminate the interlayer joints and obtain the overall effect. ?
