[0003] Although the construction concrete pipe pile grouting device in the prior art has achieved the effect of uniform grouting by vibration, there are still some shortcomings: the grouting involved in the existing construction concrete pipe pile grouting device lacks a stable supporting and positioning structure after being inserted into the concrete pipe pile, which causes the grouting pipe to easily collide with the pipe pile under vibration, thereby causing damage; secondly, the structure of the vibration rod involved is relatively simple, resulting in the amplitude effect of vibration, and then causing deviation in the vibration effect.
