ABSTRACT:
Apparatus including a digger for digging a trench to a predetermined level which is maintained by control apparatus responsive to a laser beam plane. The earth removed by the digger is directed into screening apparatus, and at least some of the fine particles therefrom are spread over the bottom of the trench to a predetermined depth. A roller unit follows the digger and presses a system of channels in the trench bottom. The coarser particles from the screening apparatus are then spread over the trench bottom and the channels. If desired, the apparatus may include means for directing a sealant over the surfaces of the channels before the coarse particles are directed thereover.
