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.
Claims14
A shoring member for an excavated hole in the ground, comprising:
- a wall with upper and lower ends;
- a plurality of tubes extending vertically along the wall and adapted to connect to a dewatering machine for removal of water from the hole;
- and
- the wall is hollow and includes spaced apart inner and outer walls, and the tubes reside at spaced intervals between the inner and outer walls to provide structural stability along the wall;
- the tubes each have a tubular wall, wherein the tubular walls of the tubes and the inner and outer walls of the wall do not share a common wall;
- and
- the tubes being formed independently of the wall.
A shoring member to retain a soil wall resulting from a ground excavation or drilling, comprising:
- a rigid hollow wall configured to engage the soil wall;
- a plurality of dewatering tubes fixed inside the rigid hollow wall at spaced distances from one another to provide structural strength along the wall, and adapted for connection to a dewatering machine, and
- wherein the tubes and the wall are free from a common wall defining the tubes.
