ABSTRACT:
A continuous concrete encased conduit laying apparatus is attached to the rear of a tractor in a cantilevered fashion and can be raised and lowered into the ground by the tractor. The apparatus has two sections which are pivotally attached to each other. The forward section is the gouger, and it has a vertical bar having a sharp leading ripper edge. At the base of the bar are attached a wedge and a cone-shaped expander for creating a cavity in the ground as the apparatus is being pulled through the ground.
The rear section which is the conduit layer, has a vertical guide tube, a concrete chute attached behind it, and a second expander forming the base of the layer. There is a hopper for holding the fresh concrete at the top of the chute. A quantity of conduit is fed through the guide tube as the apparatus is in operation. The cavity created by the two expanders is filled with fresh concrete as the conduit is laid in the cavity. The second expander can be round or rectangular in cross-section for holding several conduits, and for creating various cross-section encasements. The method includes the steps of laying the conduit and encasing it with concrete in the cavity.
