る。In the structure shown in FIG. 13, the steel sheet pile C-1 just below the concrete impervious wall b is not driven deep enough to reach a solid rock, so that the surrounding ground is compacted by earth pressure. When the steel sheet pile C-1 sinks due to the sinking, a negative internal frictional force acts on the steel sheet pile C-1 and the gutter pipe main body a does not move. A gap is formed between the main body a and each lower surface of the concrete impervious wall b, and water leaks from this gap, and the permeated water flows along the gutter pipe, which may cause damage to the embankment and the gutter pipe.

クラックが生じることを防止する。According to the present invention, since the vertical portion and the horizontal portion below the connecting portion of the water-stopping member are fixed to the gutter pipe wall under the gutter pipe, the wall of the gutter wall below the gutter pipe is backfilled with soil. In the case of sinking due to pressure or the like, the elastic water-stopping member extends to allow sinking of the watertight sheet pile wall under the gutter pipe and to prevent flooding. In addition, the watertight sheet pile wall under the gutter pipe is arranged at a predetermined distance from the bottom surface of the gutter pipe, and each vertical part and horizontal part above the connection part of the water stopping member is fixed to the gutter pipe, so that the gutter pipe is installed. When the pipe sinks, the horizontal part of the water stopping member contracts to allow the sink pipe to sink, thereby preventing the gutter pipe from cracking.

When the impermeable sheet pile wall sinks due to backfilling earth pressure or the like, the stretchable water-stopping member extends to allow the submerged sheet pile wall below the gutter pipe to sink and prevent flooding. In addition, the watertight sheet pile wall under the gutter pipe is arranged at a predetermined distance from the bottom surface of the gutter pipe, and each vertical part and horizontal part above the connection part of the water stopping member is fixed to the gutter pipe, so that the gutter pipe is installed. When the pipe sinks, the horizontal part of the water stopping member contracts to allow the sink pipe to sink, thereby preventing the gutter pipe from cracking.
