The invention discloses a double-bottom reactor bottom shielding structure for a ship and a forming method of the double-bottom reactor bottom shielding structure. The reactor bottom shielding structure of the marine double-layer bottom comprises an inner mold, an outer mold and a shielding material located between the inner mold and the outer mold, the top ends of the inner mold and the outer mold are fixedly connected with the bottom end face of an upper plate of the marine double-layer bottom, and the bottom ends of the inner mold and the outer mold are fixedly connected with the top end face of a lower-layer bottom of the marine double-layer bottom. A pouring hole for pouring a shielding material into a cavity between the inner mold and the outer mold and an exhaust hole for exhausting are formed in the outer mold. By the adoption of the structure, the reactor bottom shielding structure of the marine double-layer bottom is easy to manufacture, a large number of shielding materials do not need to be carried, only the pouring pipeline needs to be dragged for injection, the construction amount is small, and the construction period is shortened by about 70% compared with a plate laying mode. After being constructed, the reactor bottom shielding structure has the same service life as a ship and does not need to be maintained in the whole service life.

    本发明公开了一种船用双层底的堆底屏蔽结构及其成型方法。本船用双层底的堆底屏蔽结构包括内模、外模以及位于内模和外模之间的屏蔽材料,其中,内模和外模顶端均与船体双层底上板底端面固定连接,内模和外模底端均与船体下层底顶端面固定连接,外模上开设有用于向内模和外模之间空腔浇筑屏蔽材料的浇筑孔以及用于排气的排气孔。本发明提出的船用双层底的堆底屏蔽结构,采用这种结构,其制作简单,无需大量搬运屏蔽材料,只需牵引浇注管道注入即可,施工量小,施工周期较铺设板材形式减少约70%。本发明堆底屏蔽结构建造完成后,与船同寿,全寿期无需维护。
