Abstract
Main technical content: This document specifies the basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and quality commitments for shield tail sealants. This document is applicable to shield tail sealants produced using plasticizers, tackifiers, thickeners, and filler powders as main raw materials, through processes such as heating, mixing, and kneading, for use in shield-driven underground engineering operations. The sealant is injected mechanically into the gap between the shield tail and the segment to form a sealing filling material.
