Technical Field

[0001] The present invention relates to the field of construction technology, and in particular to an intelligent replacement driving device for high-strength precast concrete pipe piles and a construction method thereof. Background Art

[0002] High-strength precast concrete pipe piles are widely used in various building foundation projects due to their high strength, good durability and convenient construction.

[0003] Traditional concrete pipe pile driving equipment typically uses hammering, vibration, or static pressure, all of which have limitations in practical construction. For example, hammering easily generates significant noise and vibration, significantly impacting the surrounding environment; vibration can lead to excessive soil disturbance under certain geological conditions; and static pressure pile driving, while quieter and less vibrating, is relatively inefficient and requires larger and heavier equipment, limiting its applicability.
