Building a Super Project with XCMG Rotary Drilling Rig by the Pearl River

Recently, at the construction site of the Lion Ocean Passage project in Guangzhou, XCMG XR500E and XR460D rotary drilling rigs were deployed, seamlessly completing tasks such as setting up the mast, drilling, lifting, and soil removal, to assist in the construction of the world's largest double-deck suspension bridge with a long span! The Lion Ocean Bridge is a key control project for the Lion Ocean Passage, and XCMG rotary drilling rigs are responsible for the construction of over 400 drilled and cast-in-place piles on the right side of the main tower of the bridge. The pile diameters range from 2m to 3m, with a maximum drilling depth of 61.7m and an average rock penetration depth of about 20m. The rock hardness is 80-120Mpa, which poses higher requirements for the rotary drilling rigs.

Facing the challenging construction conditions, XCMG rotary drilling rigs lived up to expectations, completing an average of 3 to 4 piles in a span of days. XCMG service personnel were stationed at the site to ensure construction progress and accelerate efficiency, contributing to the successful completion of the project.

As the main models used in this construction, XCMG XR500E rotary drilling rigs are equipped with multi-gear drilling modes, matching the optimal torque and speed for different geological conditions, ensuring high efficiency and energy-saving. The high torque power head enables strong rock penetration, directly maximizing construction effectiveness. In addition, the main winch adopts XCMG's industry-leading single-rope technology, effectively solving the problem of wire rope wear. The dedicated telescopic crawler chassis provides strong anti-overturning capability, making the machine transportable without fear of relocation!

As a new super project in the Guangdong-Hong Kong-Macao Greater Bay Area, the Lion Ocean Passage will further promote the interconnection of infrastructure in the Greater Bay Area, helping to create a 1-hour living circle in the Greater Bay Area and effectively alleviate the traffic pressure on the Pearl River estuary crossing.
