Title:
METHOD AND SYSTEM OF BUILDING AN UNDERGROUND STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/170388
Kind Code:
A1
Abstract:
Jet grouting involves injecting grout into geological material to improve its quality; however, use of jet grouting is limited to situations in which the injection systems can be positioned relatively close to the region to be improved. However, such jet grouting systems lack the precision to form complex and stable structures. The present invention enables underground structures to be built before excavation is carried out by casting blocks in-situ. In particular, structural blocks may be formed from grouting compound and/or cement in the shape of a tunnel to be excavated, and/or around an underground asset (such as deteriorating nuclear waste containers).
