Speaking of pioneers, this three-armed god will be well deserved

Now, in the first Guinan high-speed railway construction site with a design speed of 350 kilometers per hour and a total length of 533 kilometers in southwest China, there is also such a "three-armed" god as a pioneer, who can rock all the way through the mountains and can do almost anything. Its name is-DTI rock drill rig.

In duyun city, in the south of Guizhou Province, there is a national key scenic spot-Cape Mountain-Jianjiang Scenic Spot. Borrowing from Wang Xizhi's "There are mountains and mountains here, bamboo trees are cultivated in lush forests, and there are clear streams and turbulent streams, which reflect the left and right", it is just right to describe this place. At the same time, its unique waterfalls, rivers and karst landforms are also full of poetry and painting.

However, for the construction team of Guinan High-speed Railway, such geological features undoubtedly make the construction more difficult.

At present, the entrance of the Cape Mountain Tunnel is built by our China Railway Third Bureau, with a total length of 4,935 meters and five types of surrounding rock of more than 2,900 meters, accounting for 60%. The rest are four-level surrounding rocks.

Under such complicated weak surrounding rock conditions, two sandvik DT1131i fully-computerized rock drilling jumbos incarnate as "Mr. Magic", and within six months, they have completed a series of work such as supporting the slope of the cave entrance, opening the hole with pipe shed, special supporting the leading small pipe hole, anchor construction, fully-computerized single-machine three-lane full-face excavation and so on, which is dazzling.

Under such difficult karst geological conditions, how did "Mr. Wonder" sandvik DTi series trolley achieve "turning difficulties into magic"?

As a "pioneer" in the Internet era, DTi has fully demonstrated its advantages in Guinan high-speed rail-cloak mountain tunnel project.

Speaking of the "black technology" of DTi drilling rig-full computer automation technology, customers have praised it.

DTi series drilling jumbo, according to the position of holes laid out by iSure (tunnel excavation management design software), can accurately and quickly find any position of peripheral holes, cut holes and intermediate blasting holes.

In addition to computer operation, the operator can also fine-tune the drilling process according to the change of rock conditions through "cutting-edge functions" such as hole position locking, fast stepping and dynamic correction.

At the same time, with high-frequency RD525 rock drill, high-strength boom and advanced drill pipe guidance, the best excavation results can be achieved with the lowest "battle-damage ratio".

In addition, the large tires and safety braking system are the stable guarantee for the DTi series when it takes the lead, and the safety cab equipped with "black technology" makes the noise and vibration almost die out.
