底などの水底を５４率良く掘削することができる。As shown in Fig. 1, a conventional cutter suction drainer is attached to a long box-shaped rudder (3) through a trunnion (2) to the hull (1) so that it can rotate vertically downward and forward. A cutter (4) is attached to the tip of the rudder (3), a drive device (5) such as a motor is attached to the top of the rudder (3), and the cutter (4) and the drive device are connected to the driving shaft (
6), and connect the cutter (4) with the suction pipe of the suction device (
7) and attach the tip of the rudder (3) to the clay/
When excavating the seabed or other underwater area using this type of cutter suction drainer, which is known to be suspended from a vessel (not shown), first loosen the crane and lower the tip of the rudder (3) to the seabed. When the drive device (5) is driven, the cutter (4) rotates and excavates the seabed. Rocks etc. formed by excavation are removed by suction using a suction pipe (7) of a suction device. According to the cutter suction drainer, it is possible to excavate the bottom of water such as the ocean floor with a 54% efficiency.
しかし、従来のカッタサクションドレンジャはトラニオ

いるので、水深が深くなるとラダー（３）と海底との成
す角度αは大きくなり、水深が浅くなるとラダー（３）
と海底との成す角度αは小さくなる。However, in conventional cutter suction drainers, the length from the trunnion (2) to the tip of the cutter (4) is constant, so as the water gets deeper, the angle α between the rudder (3) and the seabed increases. , when the water depth becomes shallow, the rudder (3)
The angle α between the seabed and the ocean floor becomes smaller.

も有った。This cutter suction drainer has a ladder (3
) and the bottom of j1σ is 45°, the excavation efficiency is maximized.For this reason, it is said that the excavation efficiency of the conventional cutter drainer decreases as the water P becomes shallower. There were drawbacks. It may be L7, but when the water depth becomes too shallow and the angle between the rudder (3) and the seabed becomes significantly smaller,
There was also the drawback that the lower tip of the rudder (3) contacted the seabed before the cutter (4), making it impossible to excavate the seabed.
