The stand facilities pole, production mannered null one side of the drill component and the stand facilities pole which are used

摘要

PROBLEM TO BE SOLVED: To easily perform installation work by easily inserting a standing pole easily into the bottom of water since a drill is can be made light in weight and a slurry-discharging effect of the drill at the insertion of the drill is large.;SOLUTION: This standing pole 10 which includes a synthetic-resin pole body 12 and the drill 14 is used, for example, as a pole for mooring a ship. The pole body 12 is formed by connecting cylindrical pole members 16 to one another; and the drill 14 is arranged at its tip. The drill 14 has a shape which is formed by twisting a long flat plate, and both side edges (28) form an outside spiral. When the standing pole 10 is inserted into the bottom (100) of water, the entry and discharge of sludge are efficiently performed by providing the drill 14 with a spiral surface (30) which alternately presents upward and downward portions. Thus, the standing pole 10 is smoothly inserted into the bottom (100) of water.;COPYRIGHT: (C)2011,JPO&INPIT
