混凝土拌和物布料长度大于10m时，可开始振捣作业，采用排式振捣器插入式

When the length of the concrete mixture is greater than 10m, the vibrating operation can be started. The row vibrator is inserted into the vibrating rod. When the vibrating rod group is intermittently inserted, the moving distance should not exceed the effective effect of the vibrating rod. 1.5 times the radius, and no more than 500mm, the vibrating time is generally 15 ~ 30s; the vibrator's holding time of vibrating at each position, the mixture stops sinking, no more bubbles and the cement mortar will prevail, It can't be over-vibrated, and the steel bar should be avoided during the vibrating process to prevent the steel bar from dislocating.

When the length of the concrete mixing material is greater than 10m, you can start the vibration work, use the row-type shaker insert-type shake-up bar to shake, and when the vibration bar group is inserted intermittently, Each movement distance should not exceed the effective radius of the mashing rod 1.5 times, and must not be greater than 500mm, the vibration time is generally 15 to 30s;

When the distribution length of concrete mixture is more than 10 m, the vibrating operation can be started. The immersion vibrator with row vibrator is used for vibrating. When the vibrator group is intermittently inserted for vibrating, the moving distance shall not exceed the effective radius of the vibrator One point five It shall not be more than 500mm, and the vibration time is generally 15-30s; the maintenance time of vibrator at each position shall be such that the mixture stops sinking, No more bubbles and cement mortar shall prevail, and excessive vibration shall not be allowed. In case of reinforcement during vibration, it shall be avoided to prevent displacement of reinforcement.
