(1) improve concrete compactibility and durability, to avoid man-made factors like missing or over vibration and troubles of high percentage of reinforcement and complex structure;
(2) reduce workload and save labor and power;
(3) eliminate the vibration noises, improve environment and remit construction troubles to surrounding people;
(4) simplify working process, shorten construction period and increase efficiency.
