21 Claims. (CI. 37—195) 



1. In a sonic apparatus for dredging earth material 

 froni the earthen bottom of a body of water, the combina- 

 tion of: 



a dredge tube extending downwardly to a positioir 

 adjacent to said earthen bottom, 



a resonant sonic vibration radiator at the lower end 

 of said dredge tube for stirring up earthen material 

 at said bottom and bringing it into suspension in 

 the water so as to form a slurry adjacent said low- 

 er end of said dredge tube, 



a resonant elastic vibration system vibratorily coupled 

 to said radiator, 

 ■ sonic generating means lor driving said sonic wave 

 radiator, said generating means being operable at 

 a frequency which will produce sonic wave vibra- 

 tion, and 



means for circulating said slurry up said dredge tube.

I. The method of repairing piling and the 

 like having a deteriorated section which com- 

 prises removing the deteriorated section, 

 preparing a replacement section slightly 

 shorter than the removed deteriorated section, 

 treating the exposed end surfaces of the pil- 

 ing and of the replacement section with pre- 

 servative , applying spacing members to the 

 exposed ends of the replacement section, 

 applying an epoxy resin to the exposed ends of 

 the piling and of the replacement section, 

 positioning the replacement section in the 

 piling in place of the removed deteriorated 

 section, the replacement section being of 

 sufficient length that with the spacing mem- 

 bers and the resin it contacts the exposed 

 ends of the piling forming a first set of 

 pin-receiving holes extending obliquely 

 through the replacement section across the 

 joint and into the piling below the replace- 

 ment section, and inserting pins In said holes, 

 being spaced apart around the posted piling.
