Abstract
A trench plow blade for removing cable below ground which includes a plow member having upper and a lower end and a plow wedge disposed at the lower end, the trench plow blade receiving air or water for loosening the ground above the cable or reciprocally moving the plow member relative to the plow wedge. Apparatus for the removal of cable buried in the ground and a method relating to removal of buried cable with a trenching plow blade is disclosed.
Claims20
A trench plow blade for removing cable below ground, comprising:
- (a) a plow member having an upper end and a lower end where the upper end is adapted to be disposed above ground and the lower end adapted to be disposed below around;
- (b) a plow wedge disposed at said lower end and adapted to lift the ground above the cable when the trench plow blade is moved through the ground.
Apparatus for the removal of cable buried in the ground comprising:
- (a) blade support assembly;
- (b) trenching plow blade suspended from the blade support assembly;
- (c) means for moving the blade support assembly and said trenching plow blade through the ground above the cable;
- (d) means for orienting said trenching plow blade in the ground substantially over said cable;
- (e) radio frequency means for transmitting a signal to said buried cable, and for receiving a locate signal;
- (f) microprocessing means communicating with said radio frequency means so as to communicate with said orienting means to orient said trenching plow blade in the ground substantially over said cable;
- (g) pulling means for pulling cable removed from said ground as the moving means moves the blade assembly and trenching plow blade through the ground above the cable, said pulling means communicating with said radio frequency means and said pulling means including means for piercing said cable to contact the metal in said cable so that said radio frequency means produces a locate signal in said buried cables.
A method of removing buried cable in the ground with the trenching plow blade comprising:
- (a) loosening and titling the ground above the buried cable;
- (b) moving said trenching plow blade through the ground above the buried cable;
- (c) pulling the buried cable out of the around.
