Hard rock is challenging, coal rock geology is complex, and deep hole precision control is challenging… Mines in many provinces of my country face their own challenges in drilling. XCMG’s crawler-type fully hydraulic tunnel drill rigs for coal mines Using superior performance to overcome local challenges, they have delivered excellent results in both efficiency and safety in many locations. Guizhou: …

In an underground pipeline construction project along the coast of a Middle Eastern city, the XCMG XZ1350E horizontal directional drilling rig (HDD) efficiently completed the pipeline laying task, ensuring on-time project delivery and earning widespread local acclaim for its outstanding construction quality. The coastal strata in the construction area are soft, with severe groundwater infiltration. The complex and variable geological …

Vor kurzem, a XCMG XZ5060 horizontal directional drill (HDD) successfully completed a critical pullback operation during the construction of a DN711*1300m oil pipeline project in Liaoning Province. This pipeline project serves as a critical link between energy supply and consumption. Upon completion, it will significantly reduce crude oil transportation costs and significantly enhance energy transportation capacity in Liaoning Province and the …

The Xiamen Water Supply Project is currently underway. The XCMG XZ1600F horizontal directional drilling rig, with its powerful power and precise drilling capabilities, delivers a single drill rod in just 3 Minuten, achieving an average daily drilling speed exceeding 100 Meter. With its high efficiency and stability, it has become a core tool for project advancement. The Xiamen Xiang’an Water …

The project involves the construction of new drainage pipes with diameters ranging from DN300 to DN2600mm, totaling approximately 1,700 Meter. The pipe jacking construction section will be 815 Meter lang. To address issues such as cutterhead blockage and poor mud drainage caused by sticky mud in dry rock formations, XCMG technicians, taking into account local geological conditions, innovatively developed a …

With the XCMG XDN1800-R pipe jacking machine, the cutterhead precisely reached the designated location in the receiving well, successfully completing the pipe jacking section of a single water conservancy project in Hunan Province. This marks a crucial step toward the project’s goal of water supply. The project, with a total length of 1,147 meters and a single jacking distance of …

The main tower of Pier Z4 of the Ma’anshan Yangtze River Bridge on the Chaoma Railway has been successfully capped, with XCMG’s XGT15000-600S crane lifting a 98.5-ton steel tower segment to over 300 meters for precise docking and installation. All three main towers of the bridge have now been capped, and the cantilever erection of the steel beams is about …

Crossing steep slopes and cascading waterfalls, more than ten XCMG S1 series tower cranes stand tall on the eastern foothills of the Taihang Mountains, supporting the construction of the Xiongxin High-speed Railway. The Xiongxin High-speed Railway is Shanxi Province’s first 350 km/h high-speed railway and a crucial component of the Beijing-Kunming Corridor, a key corridor within my country’s “Eight Horizontal …

Amidst the vibrant spring scenery and rippling blue waters, the majestic north main tower of the Wuhan Shuangliu Yangtze River Bridge is rising from the ground. Two XCMG XGT2230A-100S cranes are efficiently and accurately assembling the tower columns, accelerating the construction of the bridge’s north main tower. With a main span of 1,430 meters and a designed height of 211.78 …

Mit der kontinuierlichen Vertiefung der urbanen Modernisierung, Urbane unterirdische Rohrleitungen (wie z.B. Abwasserleitungen, Wasserleitungen, Gasleitungen, Wärmeleitungen, Stromkabel und Kommunikationskabel, Etc.) wird immer dichter, Bildung eines riesigen unterirdischen Rohrleitungsnetzes. Da die Lebensdauer aller Rohrleitungen begrenzt ist, wenn sie für einen bestimmten Zeitraum verwendet werden, Das werden sie …

Der Bauprozess des Horizontalspülbohrens lässt sich im Allgemeinen in drei Schritte unterteilen: Bohren von Pilotlöchern, Vor-Expandieren, und Pipeline-Rückzug. Die Qualität der Flugbahn der Pilotbohrung wirkt sich direkt auf die Größe der Rückzugskraft aus, Und die Risikovermeidung von Richtungskreuzungen spiegelt sich weitgehend im Konstruktionsprozess von Richtbohrungen wider. Daher, nur durch die Beherrschung der fortgeschrittenen Lenkung …

Mit der Entwicklung der grabenlosen Rohrleitungsbautechnik, Das Problem, dass im Stadthauptgebiet kein großflächiger Hangaushub oder Stützaushub durchgeführt werden kann, ist gelöst. In dieser Arbeit werden vor allem die Anwendungsfälle des Rohrvortriebs und der Richtbohr- und Aufnahmetechnik im Wasserbau in der grabenlosen Rohrleitungsbautechnik untersucht, und analysiert die Kosten der beiden …
