Concrete LNG full-capacity storage tank adopting unbonded prestress system
The invention relates to a concrete LNG full-capacity storage tank adopting an unbonded prestress system. The concrete LNG full-capacity storage tank comprises an outer storage tank, a storage tank dome, a plurality of storage buttress columns, and the unbounded prestress system; the outer storage tank is of a cylindrical prestress reinforced concrete structure; the bottom end of the outer storagetank is fixed on a storage tank supporting table; the storage tank dome is of a spherical arc-shaped reinforced concrete structure and is arranged at the top of the outer storage tank; the pluralityof storage tank buttress columns are fixedly arranged on the storage tank outer tank wall of the outer storage tank; the unbonded prestress system comprises a plurality of annular horizontal prestresstendons which are laid in the storage tank outer tank wall at intervals in the height direction and vertical prestress tendons which are laid in the storage tank outer tank wall at intervals in the circumferential direction; each of the horizontal prestress tendons and the vertical prestress tendons comprises a prestress steel strand and a protective sleeve; and the prestress steel strands are sleeved with the protective sleeves, so that corrosion prevention, lubrication and secondary tensioning adjustment of the prestress steel strands are facilitated. The durability, safety and reliabilityof the LNG storage tank are comprehensively improved.
本发明涉及一种采用无粘结预应力系统的混凝土LNG全容储罐，包括：外储罐，其为圆筒形预应力钢筋混凝土结构，底端固定于储罐承台上；储罐穹顶，其为球面圆弧形钢筋混凝土结构，设置在外储罐的顶部；若干储罐扶壁柱，固设于外储罐的储罐外罐壁上；无粘结预应力系统，无粘结预应力系统包括沿高度方向间隔铺设在储罐外罐壁内的多根环向水平向预应力筋以及沿周向间隔铺设在储罐外罐壁内的竖向预应力筋；水平向预应力筋和竖向预应力筋均包括预应力钢绞线和保护套，保护套套设在预应力钢绞线上，以便于对预应力钢绞线的防腐、润滑和二次张拉调整。本发明全面提升了LNG储罐的耐久性和安全可靠性能。
