GB/T 22082-2024 Reinforced concrete segments 1 Scope This document specifies the classification, dimensions and designation, raw materials, general requirements, technical requirements, test methods, inspection rules, marking and end-of-manufacturing certificate, storage and transportation of reinforced concrete segments. This document is applicable to the design, manufacture and inspection of reinforced concrete segments for rail transit, highway, railway, hydraulic engineering, municipal administration, oil and gas, electric power and other tunnel projects as well as urban underground utility tunnels. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Curve-line segments are further classified into left-curved segment (ZQ), right-curved segment (YQ), and vertical-curved segment (SQ). 4.1.2 Segments are classified by assembly positions within the ring into standard block (B), adjacent block (L1, L2), and closure block (F). 4.1.3 Segments are classified by cross-sectional shape of the tunnel into circular (Y), oval (TY), rectangular (J), quasi-rectangular (LJ), double-circular (SY), and special-shaped (YY). 4.2 Specifications Common specifications of segments are shown in Table 1.
