When the leaves are yellow and fall, when the snow flakes dye the white hills, when the flocks of cattle and sheep are grazing in the mud to find grass roots... All this indicates that the winter of Tibet at the end of October 2015 has arrived.
With a total length of more than 700 kilometers, the Lhasa-Nyingchi Railway along the Yarlung Zangbo River has just broken ground. In the background of gray stones, yellow leaves and white hills, more than 30 sets of circular lines are lined up. Among them, 20 green sunward intelligent rotary drilling rigs are the most eye-catching.

Looking back at the history of the excavation construction in Tibet with an average elevation and complex geology, we can’t help but feel a lot:
In 2001, a large number of imported brands were used as the main force in the construction of pile foundations for the Qinghai-Tibet Railway.
In 2010, the domestic rotary excavation became the main force of the railway construction of La (Lhasa) Day (Shigatse), and two rotary excavations of the mountain and river participated in the construction.
In 2015, the railway construction of La (Lhasa) Lin (Linzhi) saw no trace of imported circular excavation, and 20 sets of mountain rivers were dug into the main force.
Ten years of the rise of domestic brand rotary drilling rigs, this is the pride of domestic rotary drilling. The Shanhe Intelligent Rotary Drilling Rig, which is fully innovative and designed in key systems such as working equipment, walking chassis, hydraulic system and control system, has become a leader among state-owned brands with strong rock-input capability and high stability. The pride of the rotary drilling rig. We are looking forward to the Shanhe Intelligent Rotary Drilling Rig to contribute more to the development of the Qinghai-Tibet Plateau in the future.
