SOLUTION: This working machine has a working machine body 2 and a groove shape-forming body 3 for forming a waterproof sheet-burying groove D installed in the working machine body 2. A waterproof sheet-supporter 5 for supporting the waterproof sheet 4 sent out to the waterproof sheet-burying groove D is installed in the working machine body 2. A waterproof sheet-introducing body 6 for introducing the waterproof sheet 4 sent out from the waterproof sheet-supporter 5 to the waterproof sheet burying groove D, and for arranging the waterproof sheet 4 along the waterproof sheet-burying groove D is installed. The waterproof sheet-introducing body 6 is positioned at the rear part of the groove shape-forming body 3, and installed in the working machine body 2 through a spindle 41 so as to be turned upper and lower. The working machine body 2 has a positioning means 57 for positioning the waterproof sheet-introducing body 6 rotatably movable in the upper and lower direction to the waterproof sheet-arranging position.
