Amid the roar of the XCMG XR580HD rotary drilling rig
Qingshen Hanyang Minjiang Grand Bridge Project
** pile foundation drilling completed
Main pile foundation construction enters the fast lane
The Qingshen Hanyang Minjiang Grand Bridge has a total length of 2348.5m. The entire bridge has 323 pile foundations and 50 pile caps in total, all of which are end-bearing piles. The XCMG XR580HD rotary drilling rig is responsible for the construction of large-diameter pile holes. The XCMG rotary drilling rig operates on the trestle bridge; the bridge deck is 12m above the water surface, the water depth is 5m, the construction pile diameter is 3m, and the pile depth is 63m.
The on-site geological structure is complex with obvious stratification
Underwater operations are even more difficult
When performing large-diameter pile hole operations of Φ3m or more
There are problems of difficult coring and difficult salvage of crushed stone
The XCMG XR580HD rotary drilling rig
Staged drilling
Shortens the hole-forming time to 40 hours
Construction efficiency is highly recognized by the customer
XCMG rotary drilling rigs focus on the development of cutting-edge construction technology and attach importance to innovation in product technology and construction methods. They have extensively participated in projects such as the Chongqing-Xi'an High-Speed Railway and Chongqing East Railway Station, demonstrating excellent quality under tests in various construction environments and helping customers create high-quality benchmark projects!
