The invention relates to a pump well structure for a B-type LNG (Liquefied Natural Gas) cabin and a ship with the B-type LNG cabin. The pump well structure comprises a pump well enclosure bulkhead, a pump well bottom plate, pump well edge reverse reinforcing ribs, a reinforcing plate and a pump well middle embedding plate, a B-type cabin bottom plate is arranged at the bottom of the B-type LNG cabin, a pump well opening is formed in the B-type cabin bottom plate, the pump well enclosure bulkhead is arranged below the B-type cabin bottom plate along the pump well opening by a circle, and the pump well bottom plate surrounds the lower end of the pump well enclosure bulkhead to form a pump well body; the pump well main body is in a long waist circle shape along the ship width direction; the pump well edge reverse reinforcing rib is arranged above the B-type cabin bottom plate along the well mouth of the pump well; the reinforcing plate is arranged in an included angle area between the pump well enclosure bulkhead and the B-type cabin bottom plate and corresponds to the position of the embedded plate in the middle of the pump well; and the pump well middle embedding plate is embedded into the pump well main body. According to the pump well structure, the long-waist-circle-shaped design is adopted, the situation that the pump well structure and a B-type cabin bottom plate or a pump well bottom plate form three-face-intersecting sharp corners can be effectively avoided, stress concentration at the sharp corners is avoided, and the tightness of the whole pump well area structure is guaranteed.
本发明涉及一种用于B型LNG舱的泵井结构及具有B型LNG舱的船,包括泵井围壁、泵井底板、泵井边缘反面加强筋、加强板、泵井中部嵌入板;B型LNG舱的底部设有B型舱底板,B型舱底板上设有泵井开口,泵井围壁沿泵井开口一圈设置在B型舱底板的下方,泵井底板围合在泵井围壁下端形成泵井主体;泵井主体沿船宽方向呈长腰圆型;泵井边缘反面加强筋沿泵井井口设置在B型舱底板的上方;加强板设置在泵井围壁和B型舱底板之间的夹角区域与泵井中部嵌入板的位置相对应;泵井中部嵌入板嵌入泵井主体内。本发明的泵井结构采用长腰圆型的设计,可有效规避其与B型舱底板或者泵井底板形成三面相交的尖角,避免了尖角处的应力集中,以保证整个泵井区域结构的密性。
