This is where every mega project truly begins — deep below the surface

🕳️🏗️ This giant machine is a Zoomlion rotary drilling rig — built to create the deep foundations holding up massive buildings and bridges.

Using a heavy-duty kelly bar and drilling bucket, the rig bores deep into the ground to form large-diameter foundation piles.

Around the drill, the huge steel casing prevents loose soil and mud from collapsing into the hole during excavation. ⚙️

Meanwhile, ground crews carefully monitor every step because one mistake underground can affect the entire structure above.

This is where every mega project truly begins — deep below the surface. 🌎🏗️
