Abstract
A reaming tool forms a hole in the ground with a sidewall and a floor, and a deepened channel around the perimeter of the floor adjacent to sidewall. Fluid is provided during excavation to form a slurry to hold the sidewall and prevent cave-in of material into the hole. After the hole reaches a desired depth, the reaming tool is removed, and a shoring wall is inserted into the hole through the slurry and seated in the perimeter edge channel. The shoring wall includes vertical tubes for connection to a dewatering machine. Then, the slurry can be vacuumed from the hole, while the dewatering machine keeps the empty hole as dry as possible. Extending the shoring wall into the channel beyond the floor of the hole helps seal flow of water from entering the hole.
