Sunward rotary drill power construction of the world's second suspension bridge
Recently, located in the Dongting Lake into the Yangtze River at the confluence of Yueyang City, the seven mountain, the second in the world, the first domestic large span steel truss girder suspension bridge -- big Dongting Lake expressway bridge is the construction of which be in full swing, sunward, rotary drilling rig SWDM42 body frames spectacular. Sunward, as a technology enterprise with profound scientific and technological background, provides various sources for the world to adapt to different working conditions. It is the source of sunward's intelligence innovation. In the development of new rotary drilling rig, no effort to move forward.
Dongting Lake bridge is a large mountain speed key control project of hangrui national highway Linxiang to Yueyang section of the East yoshiie Lake community, Yueyang Tower area across Dongting Lake, West Mountain King reed field, the main bridge of the Twin Towers double span steel truss girder suspension bridge, a total length of 2390 meters, the construction has the characteristics of large scale, high technical difficulty, the building structure is complex, the equipment into the rock drill hole, loss of ability, the whole efficiency and stability have high requirements. In the construction process, sunward SWDM42 has won the praise of users by its stable quality and fast speed.
It is understood that the sunward SWDM42 rotary drilling rig uses self-developed electronic control system, fully functional, advanced and reliable, convenient maintenance, auxiliary outrigger, functional diversity. In addition, Sunward Intelligent multifunctional rotary drill is suitable for construction of sand, clay, gravel layer and weathered rock under complicated geological conditions, construction and is widely used in highway, railway overpass, viaduct of large diameter piles and pile foundation of high-rise building. In recent years, sunward rotary drilling rig has been widely recognized by the market for its reliable quality, original and advanced technology, and has achieved great success in the global engineering construction.
