Description

Technical Field

[0001] The utility model relates to the technical field of pile breakers, in particular to a hydraulic pile breaker used for pressing into a soft base layer to break piles. Background Art

[0002] Hydraulic pile breaker is a kind of pile breaking equipment driven by hydraulic pressure, mainly used for breaking concrete pile heads. Hydraulic pile breaker transmits power to multiple cylinders through the hydraulic system, so that the cylinders generate high pressure, thereby pushing the drill rod and squeezing the pile body to achieve the purpose of breaking the pile head.

[0003] When breaking piles in soft base layers such as muddy strata, it takes a lot of time and manpower to clean the muddy soil around the pile body. If it is not cleaned, the pile breaker needs to be pressed into the soft base layer to break the pile around the pile body trapped in the soft base layer.
