Summary:The invention discloses a low-gas-volume water jacket core structure and a core assembly method thereof, and relates to the technical field of water jacket cores. The core assembly method comprises the following steps that step 1, a sand core is manufactured, a main body part of the sand core adopts Yangtze River low-gas-volume precoated sand, a sleeve core adopts ceramsite as a raw material, the raw material is pretreated through the stirring and screening process, and the pretreated raw material is manufactured into the sand core in a heating mode; and step 2, coating is applied to the interior of the sand core manufactured in the step 1, the coating is water-based coating, the sand core is placed in the coating, then the sand core is taken out, the baume degree is controlled to be about 30, and then baking is conducted for 40 minutes at the temperature of 150 DEG C. The sand core is conveniently placed in a shell under the action of the cavity, the shell is conveniently fixed under the action of a circular
