The academic exchange meeting of full rotary drilling rig for ddnan heavy industry and Construction Research Foundation

With the accelerated process of city, more and more construction projects of complex geological environment, full casing rotary drilling rig for its environmental protection, reliable and high efficient drilling technology increasingly wide range of applications, especially in the city subway, deep foundation pit, waste pile piles (underground) construction, high-speed rail, road and bridge, clean up the construction and reinforcement of pile field reservoir dam.

With the accelerated process of city, more and more construction projects of complex geological environment, full casing rotary drilling rig for its environmental protection, reliable and high efficient drilling technology increasingly wide range of applications, especially in the city subway, deep foundation pit, waste pile piles (underground) construction, high-speed rail, road and bridge, clean up the construction and reinforcement of pile field reservoir dam.

At the meeting, the general manager of Chen Jianhai made a report entitled "the development and application of full casing full rotary drilling rig in China". In more than 2 hours of the report, the general manager Chen Jianhai first of all introduces full casing rotary drilling rig and the development process, followed by information, equipment, engineering construction of video animation etc. fully demonstrated the application of full casing rotary drilling rig, content is very rich. Chen Jianhai general manager also conducted in-depth exchanges and discussions with the present researchers on related issues, and the atmosphere was warm.

This report broadened our vision and deepened our understanding of full - casing full rotary drilling rig and its construction methods. The director of Gao Wensheng said that the next step to build the foundation will be a strategic partnership with the ddun heavy industry.
