PURPOSE:To improve working efficiency, by a method wherein an endless linear body is located along the inner peripheral surface of a casing body, and is made to run and stop through the working of a driving mechanism, and an engaging means, engaged with a covering body, is located in the direction of the length of the linear body. CONSTITUTION:After the lower part of a bagform covering body is engaged with an engaging mean 9 of an endless linear body 4, a sprocket 6 at the upper end of the linear body 4 is driven by a motor 7 to convey the linear body 4 in a casing body 1. After the covering body with a given length is inserted, the linear body 4 is brought to a stop once, and the interior of the covering body is filled with sand to form a covered sand pile body. The linear body 4 is moved again, and the body 1 is lifted up as the covered sand pile body is forcibly discharged from the lower end of the casing body 1. |
