Grab the grab with the full-turn rig

Nanjing Yaohang Construction Engineering Co., Ltd. used 2 sets of shielded heavy-duty full-sleeve full-rotary drilling rigs (DTR2605H, DTR2005H) for construction, using a grab grab to match the soil for construction, the pile diameter is 1.5m, the pile depth is 85m, and the backfill is floated. The stone boulder formation, and finally into the middle weathered rock 19-20m, is one of the cast-in-place piles with complicated geological environment and difficult construction.

Grab the soil

 

Nanjing Yaohang Construction Engineering Co., Ltd. uses Kengbo Chong grab to take soil for construction, and the diameter of the boulder stone reaches 50-80mm.

Rotary drilling rig

 

Nanjing Yaohang Construction Engineering Co., Ltd. uses a rotary drilling rig to cooperate with the shielded heavy-duty full-sleeve full-rotation drill (DTR2605H), and finally enters the medium-weathered rock of 19-20m. The geological predicament is complex and the construction is difficult.

Rotary drilling rig

Nanjing Yaohang Construction Engineering Co., Ltd. uses a rotary drilling rig to cooperate with Dunan Heavy Industry full casing full-rotation drill (DTR2005H), and finally enters the middle weathered rock 11-12m. The geological predicament is complex and the construction is difficult.
 

Perfusion, hole formation, transfer positioning

Nanjing Yaohang Construction Engineering Co., Ltd. casts the pile into the hole and moves the machine.
