"""콘크리트 포장 전개식 — 면적 × 두께 · 거푸집 양면 · 수축줄눈 (2026-09-15 브레인 포장 둘 ①~⑤·ⓐ).

근거
    임도기술교본 3-2 기본설계 — 포장 폭 3.0m · 두께 0.2m · 곡선부 확폭
    임도기술교본 부록 4-7 7-1 3.5.1 — 「수축줄눈의 간격은 4-6m를 기준」
    산림품셈 12-6 콘크리트 포장(인력) · 12-7-1 포장절단 · 12-8 콘크리트 포장 거푸집
    실무 울진소광 「포장및난간개거」 — 면적 = B × L · 거푸집(1면기준) = 2L ·
        수축줄눈 = 내림(L÷6) × B (103m·B 3.5 → 59.5 · 418m → 241.5) · 「포장확폭」 줄눈 = 면적 ÷ 6
판정 — 폭·확폭·두께는 **B06 에서 잇고 칸이 이김**(한 값 원칙) · 비닐·철망은 고르기(기본값 없음).
