Ningbo Yonggong Technology Co., Ltd.
Ningbo Yonggong Technology Co., Ltd., established in 2017, is a national specialized and sophisticated Little giant enterprise specializing in scientific research designequipment R&D and engineering construction as well as a national new technology enterprise. As a system service provider in the field of mechanical method cross passage for rail transit, it provides advanced tunneling equipment, process technology, and complete engineering construction services.
The company's main products are mechanical method special tunneling mac es for connecting passages, including shield machines (Type I) and pipe jacking machines (Type II).

Service Support
We master core technologies of mechanical cross passages with patented certifications, and have won many industry honors including the Special Science and Technology Progress Award from the Chinese Society for Rock Mechanics and Engineering.
We adopt fully-sealed, strongly-supported and micro-reinforced construction techniques to ensure safety and high efficiency.Furthermore, the built-in pump room technology significantly reduces construction difficulty and risk, and enables simultaneous construction of the pump room and the crossing passage.
We have completed the construction of over 300 channels in 18 cities across the country, and have implemented key projects in Qingdao, Tianjin, Zhengzhou, Shanghai, and other places, boasting ample practical experience.
Cost-effective Overall Solution
The construction of crossing passage using mechanical methods is not only safe, efficient, and fast, but also relatively cost-effective. Additionally, the technology is scalable and can be widely applied in shield tunnel crossing passage projects across various fields such as transportation, municipal engineering and water conservancy.-
