Product Introduction

The hydraulic walking super-high pressure jet grouting SHJP-60 drilling rig is a special large-scale drilling rig developed and produced according to the needs of Beijing's national key projects. It is suitable for pile foundation construction of high pressure jet grouting engineering and soft foundation reinforcement engineering.

The drilling rig has the following characteristics:

1. The pile frame is a hydraulic walking structure, which can lift and fall the column by itself, walk, rotate, accurate, reliable, high construction efficiency, low labor intensity and so on.

2. The pile machine adopts the combination of hauling and shipping, with strong integrity, convenient site transfer and low cost.

3. The electrical, hydraulic, operating and monitoring instruments of the whole machine are all concentrated in the driver's room, which is convenient for the driller to operate.
