Sany Rotary Drilling Rigs Fighting for the "Super Project"!
September 24,2024
The Kunming Changshui International Airport expansion project is one of the 102 major modern airport construction projects in the country's "14th Five-Year Plan". It is a major infrastructure project that supports Yunnan's construction of a radiation center facing South Asia and Southeast Asia, actively serves and integrates into the "Belt and Road" construction, the development of the Yangtze River Economic Belt, and the implementation of the civil aviation strong province strategy.
Recently, with the help of Sany rotary drilling rigs, the project's hole-forming operations are in full swing, and all efforts are being made to speed up the project to safeguard the subsequent pile foundation construction.
It is reported that the airport expansion project includes the construction of a new 730,000 square meter T2 terminal and a 131-aircraft apron; the construction of the East Second Runway and the West Second Runway; the construction of an 80,000 square meter integrated transportation center and other supporting facilities. It is worth noting that in this drilling operation, the underlying structure is complex, with backfilling of green rock, cross-holes, and half-side rocks, and the natural compressive strength of the rock in this project can reach up to 60-70 MPa. The complex geological conditions and high requirements have posed considerable difficulties and challenges to the project construction.
Faced with such a difficult project, the contractor had extremely strict requirements for construction equipment. Among many brands, Sany rotary drilling rigs stood out with their stable, reliable and efficient features, becoming the preferred equipment of the construction party. The on-site operator said: "Not only is it powerful and fast in drilling, but it also has low fuel consumption."
With the support of hard power, Sany rotary drilling rigs have large displacement and high-power engines that are powerful, energy-saving and environmentally friendly; the advanced power control system can give full play to the performance of pumps and valves; in addition, the main winch has a fast lifting and lowering speed, which can calmly deal with emergencies on site; the intelligent control system has the function of automatic adjustment and real-time display of the verticality of the drill mast, thereby significantly improving the stability of the hole wall and the quality of the hole during the pile foundation construction process. The system accurately integrates key performances such as pressure, torque, and lifting force to ensure excellent performance in the drilling operations of hard rocks, deep holes and large-diameter piles, and can achieve efficient and fearless drilling operations even in the face of slightly weathered hard rock formations.
In addition to stable and efficient performance, Sany rotary drilling rigs also have outstanding performance in energy saving. The newly developed positive flow control system can reduce energy consumption by 8%, and the comprehensive fuel energy saving is more economical.
