When the filler is injected into the space between the spans, the bag body 1 is evacuated, and the tubular portion 6 of the bag body 1 is attached to the end of the main pipe 8 extended in the tunnel 7. To do. Then, the lower air chamber 13 is injected and expanded. In this state, the bottom 10 of the bag body 1 and the left and right side surfaces are in close contact with the horizontal floor plate 15 and the left and right circular arc surfaces that are placed at the bottom of the tunnel 7, and the height in which the lower air chamber 13 is regulated by the partition wall 11 The upper air chamber 12 is expanded to the position and the upper air chamber 12 is in a contracted exhaust state. The partition wall 11 is located at a predetermined height from the top end of the tubular portion 6, that is, at a top end 16 of the tunnel 7 where a space for workers to freely enter and exit can be secured. Therefore, the worker can freely move in and out from above the partition wall 11 to correct the set position of the bag body 1 and to perform the air bubble removal work of the filling material.

填される。When the filling material is filled to the height of the partition wall 11, the upper air chamber 12
Is inflated, the upper side of the upper air chamber 12 and the top end 16 of the tunnel 7 are left with a slight gap left to close the partition 11 from above. Then, a filling material injection hose (not shown) is pushed into the tunnel 7 inside the bag body 1 from the gap between the top end 16 of the tunnel 7 on the upper side 9 of the upper air chamber 12 to unfill the upper portion of the tunnel 7. The filling material is filled in the above position, and the filling material is injected and filled into the entire tunnel 7 blocked by the bag body 1.
