The invention discloses a thin wall tyre body manufacture method used for the filling of the cast-in-place concrete. A tyre body bottom plate and the peripheral side walls which are connected into a whole body are manufactured with hydration reaction mixture such as wet cement mortar and light cement mortar, one or more inner mold holding plate(s) can be covered on the opening surrounded by the peripheral side walls, at least one side edge of the inner mold holding plate is extended outside the side wall of the tyre body side, and hydration reaction mixture such as wet cement mortar and lightcement mortar is coated on the top surface of the inner mold holding plate to form the top plate of the thin wall tyre body; when the peripheral of the top plate is formed, except the extended side edge of the inner mold holding plate, all other side walls of the tyre body are integrated with the type body side walls with the corresponding positions under the wet state into a whole body, after the pre-hardening of each surface of the thin wall tyre body, the inner mold holding plate is drawn out, the thin wall tyre body manufactured by the invention is the seamless body structure, and the inner mold holding plate can be repeatedly used.
