Large Diameter and Depth Rotary Digging Pile Driver

Rotary drilling rig is a kind of construction machinery that is suitable for forming hole in construction foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers. It is widely used in the construction of various foundations such as cast-in-place piles, continuous walls, and foundation reinforcement. The hole diameter of rotary drilling rigs can reach 1.2~1.5m. The hole depth is 10-15m, which can meet the requirements of various large-scale foundation construction
