A Core of 2m*Φ1.5m Integrally Taken out by XCMG Rotary Drilling Rigs
Recently, large-tonnage rotary drill rigs of XCMG has successfully completed 36 large-diameter piles with great depth and hardness in the project of Linhuaiguan cross-Huaihaihe river bridge. The drill rig and drilling tool of core barrel function well.
For such a big cable-stayed bridge with the longest span over the Huaihaihe river, pile foundation construction is the key point. Living up to expectations, 4 XR580HD rotary drill rigs perform excellently in the project under the difficulties like taking out a total of 36 pier piles with a max drill diameter of 2.8m and max drill depth of 94m in the moderately weathered gneiss.
Moreover, a complete rock core with a diameter of 1.5m and a height of 2m is taken out in the first drill at once.
Equipped with various international advanced technologies, such as triangle luffing mechanism, single layer of the main winch driven by double-motors, electrical multi-controller and self-removable retractable H-shaped chassis, XR580HD rotary drill rigs specialize in the application of large holes, deep piles and hard formation conditions, widely used in large-scale projects like cross-river and cross-sea bridges.
XR580HD rotary drill rigs not only provide high efficiency but also ensure good stability with little defects, highly praised by all staff in the job site.
