After traversing 135MPa super-hard geology, the XCMG XZ3600 horizontal directional drilling rig, which specializes in “hard bones”, once again became an “expert” in underground crossing. Recently, the large-tonnage explosive model XZ3600 of XCMG horizontal directional drilling rig successfully crossed the Songhua River again, which also refreshed the record of the longest distance traversed by XZ3600 horizontal directional drilling rig to 2400m!
The crossing is the Dehui-Fuyu gas pipeline project, a cross-city pipeline project. The entry point is on the side of Fuyu City, and the excavation point is on the side of Dehui City. The diameter of the pipeline is 323.9mm, the designed entry angle and the excavation angle are both 12°, and the actual total crossing length is close to 2400m. The project uses XCMG large-tonnage horizontal directional drilling rig XZ3600 for crossing.
The pipeline is designed to be buried at a depth of 45m at the bottom of the Songhua River. During construction, it needs to pass through complex formations such as sand, gravel, and granite. The maximum rock hardness is 68.5MPa, which makes the construction difficult and risky. XCMG XZ3600 showed consistent reliable and stable performance during the construction process, and cooperated with the professional construction team to complete the pipeline laying work well, which was an important hurdle for the Dehui-Fuyu Gas Pipeline Project.
XCMG XZ3600 horizontal directional drilling rig has many advantages such as higher intelligence, better performance, and more energy saving. It has played the role of “manager” in the pipeline crossing and laying projects of many major projects of people’s livelihood. “Construction restricted area” was successfully lifted!
In August 2020, the “Dongdong Line” crude oil long-distance pipeline will pass through the 135MPa moderately weathered granite rock formation. XCMG XZ3600 has successfully “gnawed” this hard bone with its core technology, stable performance, and complete customized construction method. Successfully dragged back within the time.
In December 2019, in the Liaohe River crossing project, XCMG XZ3600 horizontal directional drilling rig operated at the bottom of the river at a depth of 28m. It only took 6 hours to complete the towing pipe. The excellent quality and stability of XCMG’s equipment have been praised by customers.
In October 2017, two large-tonnage horizontal directional drills of XCMG XZ5000 and XZ3000 crossed the Songhua River hand in hand, creating a “super project” in the history of crossing. Now XCMG XZ3600 crosses the Songhua River again, demonstrating the hard-core strength of XCMG horizontal directional drilling rig as a “practical weapon” of various key energy and livelihood projects!
