At a corner of the construction site for Qingdao Jiaodong International Airport, three Lovol rotary drilling rigs made a collective appearance, jointly supporting the airport's foundation construction.


　　The sand layers and backfill layers in the strata at the construction site are unevenly distributed, and the bedrock at depth is hard, making foundation pit construction difficult. The Lovol FR630D rotary drilling rig, with its high efficiency, stability, and strong geological adaptability, has won recognition from the main construction unit of the project.
