T/GLYH 002-2023 Threaded reinforcing stop water stopper

Scope

Scope: This document specifies the classification and marking, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of reinforced reactive waterstop strips. This document applies to the production and engineering application of reinforced reactive waterstop strips that are either fully or partially cast into concrete or externally attached to concrete surfaces in infrastructure engineering structures. Main technical content: The reinforced reactive waterstop strips proposed in this document innovate the waterstop mechanism, improve anti-water seepage performance, enhance waterstop effect, enhance the safety of underground structures, and reduce engineering maintenance costs. To further expand the promotion and application of reinforced reactive waterstop strips, standardize production processes and process controls, and promote product standardization, serialization, and industrialization, this document is formulated. Reinforced reactive waterstop strips improve the tensile performance of deformation joint waterstop strips and enhance the waterstop strips' ability to adapt to the expansion and contraction of concrete joints. Based on the waterstop mechanism of adhesive sealing and anti-drainage combination, the waterstop strip structure is optimally designed from the perspective of blocking water seepage channels. On the existing rubber, steel-edged rubber, and steel plate substrates, a waterstop function area is added and a reactive layer is compounded on it. Through the reactive layer, the waterstop strip and the concrete are adhesively sealed to improve the waterstop effect.
