Please be cautious to these following conditions when using Rotary Piling Rig:
1. The verticality of the hole in the soil and the setting of the steel tube has a great influence on the verticality of the pile.
2. Positioning with the concrete casing and steel pipe protection supporting reasonably can effectively shorten the drilling machine positioning time and improve the construction efficiency.
3. Use rotary bucket in soft rock and soil to make hole once. Work in hard rock with a spiral drill into a small hole, and then use the rotary bucket to expand into holes.
Rotary piling rig for subway engineering drilling pile construction has more advantages and better applicability, it can significantly improve the construction efficiency and engineering quality. In a reasonable selection of construction methods and construction techniques, it can maximize the savings of material, financial, human and other resources. Rotary piling rig is an outstanding Environmental Machinery.
