Recently, the key housing construction pile foundation project in an Asian city has entered the concentrated construction phase, with a large number of piles and prominent formation construction difficulties. XUGONG's XR178E rotary drilling rig has been dispatched to the construction site as the main operating machine; relying on a stable construction penetration rate of 3.4 m/h, it completed the hole-forming and grouting of five standard pile foundations in a single shift, easily handling multiple challenges such as hole collapse and hard rock drilling, and accelerating and empowering the project construction.

The site's formations alternate between soft and hard layers. The loose soil layer from 0 to 6 meters is prone to hole collapse, while the moderately weathered rock formation at the bottom from 6 to 6.8 meters is hard, with high resistance when drilling into rock; ordinary equipment drills slowly and is prone to hole deviation. After comprehensively comparing multiple models, the customer found that the XR178E combines the advantages of a small body, strong power, and low fuel consumption. It can handle complex formations while reducing overall construction costs, making it the optimal choice for the project.

The XR178E is equipped with a high-power engine and a negative-flow hydraulic system. It prevents hole collapse when drilling in soil and has strong crushing penetration in rock layers. The whole machine operates smoothly, and the verticality of the formed holes meets standards. The equipment's average construction efficiency reaches 3.4 m/h, stably completing 5 standard pile foundations per shift. A single pile requires only 2 hours from hole formation to grouting, greatly shortening the construction cycle per pile. The advanced power and hydraulic control system simultaneously achieves reduced consumption and increased efficiency, with lower fuel consumption during high-intensity continuous operation, balancing construction speed and economy.

The person in charge of the construction contractor stated that the XR178E has extremely strong adaptability to alternating soft and hard formations; it does not stall when entering rock, forms holes well, and rarely requires rework. Its fuel consumption performance during long periods of uninterrupted operation exceeded expectations, and the equipment has a low failure rate, requiring no frequent shutdowns for maintenance. This effectively shortens the construction period and reduces fuel and operation and maintenance expenses, resulting in significant overall returns. The smooth progress of this residential project relies on the outstanding performance of the XR178E, which balances high efficiency and low consumption. Efficient pile formation strongly guarantees the project's completion on schedule. Based on the infrastructure market, XUGONG continues to demonstrate the strength of China's construction machinery with rotary drilling equipment adapted to diverse working conditions. In the future, it will continue to deepen its presence in the Asian pile foundation market, empowering more housing construction infrastructure and municipal projects with reliable equipment and energy-saving technology, and supporting the high-quality development of regional infrastructure.
