RESEARCH ON SHIELD TUNNELING MUD AND SAND IN HYDRAULIC FILLING CONSTRUCTION
A compositional analysis was conducted on shield tunneling mud and sand slag samples.In order to meet the requirements of hydraulic filling technology,a self-propelled rake suction ship was used to improve the construction technology.The shield tunneling mud and sand were directly blown to the site,and the pipeline layout and loss control technology during the entire hydraulic filling process were improved.At the same time,a compara-tive analysis of the cost of specific projects using shield tunneling mud sand filling was conducted in order to provide reference for similar projects.
