I. Pre-Export Preparation: Lay a Solid Foundation for BusinessAs large-scale construction machinery and equipment, the preparatory work before exporting rotary drilling rigs directly determines the success of the business. Firstly, market research and access analysis require focusing on the target m Read More

1. Overview of CFA MethodCFA (Continuous Flight Auger) method, namely the continuous auger drilling and grouting pile-forming method, is a cast-in-place pile construction technology without mud wall protection. Its core principle is to form holes by continuous drilling with auger drill pipes, while Read More

For the construction of 126 pile foundations of the approach bridge of a river-crossing bridge, the Sany SR235-C10 rotary drilling rig was selected as the main equipment to solve the problems of complex geology and high groundwater level.
By adjusting parameters to adapt to different soil layers, the drilling rig increased the efficiency by nearly 3 times. 126 pile foundations were completed in 102 days, shortening the construction period by 15% and reducing the cost by 12% compared with the plan.
Finally, the proportion of Class I piles reached 98%, which confirms the efficiency and reliability of the rotary drilling rig in bridge pile foundation construction and provides a reference for similar projects. Read More

As a "powerful tool for deep holes" in foundation construction, the reliability of rotary drilling rigs is directly related to project progress and cost control. Many construction teams neglect maintenance details, leading to frequent equipment failures and a service life reduction of more than 30%. Mastering refined maintenance skills is the core key to extending the equipment's service life. Read More

Today, as infrastructure construction and the "dual carbon" goals are deeply integrated, rotary drilling rigs, as the core equipment for pile foundation construction, are undergoing a crucial transformation from "scale expansion" to "quality upgrading". The green transformation and intellige Read More
