From September 21 to 23, the 6th Deep Foundation Engineering Development Forum will grandly open. With the theme of “Theory, Practice and Innovation in the Development of Deep Foundation Engineering” and the purpose of promoting the sustainable development of deep foundation and underground space engineering, this forum will focus on scientific and technological innovation. It is a major exchange and cooperation platform integrating “research, survey, design, construction and equipment manufacturing,” and will also represent a reform of the past years' practices of exclusive hosting, closed-door discussions and repeated participation. This forum has received strong support from experts, professors, scholars, enterprises and institutions, engineering and technical personnel, and doctoral and master's students from the industry. Among them, Zhang Hao, a senior designer at CRRC Beijing Heavy Industry, will attend the forum and deliver an excellent report entitled “Introduction to CRRC Series Products and Large Rotary Drilling Rig Equipment and Construction.”
　　Beijing CRRC Heavy Industry Machinery Co., Ltd. entered the field of rotary drilling rig manufacturing in 2004. Relying on CRRC's strong scientific research capabilities in the rail transit field and its strength in heavy equipment manufacturing, the company has successively successfully developed the TR138D to TR580D series of rotary drilling rigs.
　　As the country once again makes major investments in infrastructure construction, the number of large-scale pile foundation projects is increasing day by day. This year alone, seven bridge projects across the Yangtze River have started construction. This report will proceed from the simple to the profound, analyzing the specific application of large rotary drilling rigs in foundation construction by introducing current mainstream large-diameter construction equipment, main hole-forming processes and typical construction cases…… For more exciting content, industry peers are cordially invited to attend the conference and exchange guidance on site!
