China Railway Shanhe hosted the 21st Cross-Strait Tunnel and Underground Engineering Academic and Technical Seminar

August 19-20 days，The 21st Cross-Strait Tunnel and Underground Engineering Academic and Technical Seminar in 2023, hosted by China Railway Shanhe（TUSS2023）Successfully held in Nansha, Guangzhou。

The conference is based on“Tunnel Innovation Technology and Major Engineering Practice”As the theme，Tunnel and Underground Engineering Branch of China Civil Engineering Society、Underground Engineering Branch of Chinese Society of Rock Mechanics and Engineering、Tunneling Association of Taiwan、Guangzhou Municipal Engineering Design & Research Institute Co., Ltd.、Guangzhou Metro Group Co Ltd、Shenzhen Metro Group Co Ltd、Wuhan Institute of Rock and Soil Mechanics, Chinese Academy of Sciences and other units attended the meeting.。

Zhao Youhong, deputy general manager of China Railway Shanhe, was interviewed by Guangdong TV at the conference site.：“China Railway Shanhe is committed to the R & D and manufacturing of tunnel and underground space development engineering equipment.，Give full play‘Equipment+Construction’The advantage of，Realize intelligent engineering construction、Fewer people、High quality development。”

Han Cheng, chief engineer of China Railway Shanhe Research Institute, was specially invited to the conference.《Application and Prospect of Compound Shaft Tunneling Machine》 Presentation ，In view of the scarcity of land resources in urban centers and the need to achieve efficient and intensive use of land.，He started from the shaft boring equipment.，This paper analyzes the construction methods and the characteristics of various equipment for shaft construction in the world.、Advantage，Propose a solution。

Introduced in the report，Composite shaft Boring Machine designed by China Railway Shanhe，Aim at upper soft and lower hard、Combination of hard and soft、And complex formations such as superhard rocks.，It can provide a safe and efficient tunneling plan，It not only realizes fully automatic and intelligent operation,，But also meet that requirement that the well is drilled without goe down the well.、The land subsidence is small、Low noise、Small floor area and other safety and environmental protection requirements，It can solve the problem of parking in the central city.，The equipment is popularized and applied to the starting and receiving wells of a shield or a pipe jacking machine.、Water Conservancy、Mine、Energy、Warehousing and other fields，It will further realize the efficient and intensive use of land resources.。
