Patent number: 11988044Abstract: 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.Type: GrantFiled: September 16, 2022Date of Patent: May 21, 2024Inventor: Ted R. Dimitroff

Patent number: 11760034Abstract: A method of borehole pipe installation begins with unfinished stick pipes brought to the installation site and then machined or cut to form male and female ends. The pipe ends are then locked together to form a flush joint. The lock can be provided via a groove cut into one of the ends for receipt of a lock gasket, which secures and seals the joint when the pipes are pushed together, and prevents the pipes from being pulled apart. Alternatively, to the groove and lock gasket, the ends can be glued and screwed together, with the screws allowing the joined pipes to be pulled through the borehole before the glue is dry. The pipe joint has flush exterior and interior surfaces to minimize borehole clearance and maximize fluid flow through the pipe assembly.Type: GrantFiled: January 14, 2022Date of Patent: September 19, 2023Inventor: Ted R.

Patent number: 10786839Abstract: A pipe cleaning tool has a longitudinally extending hollow shaft with a honer head on the forward end and stabilizing legs behind the honer head. The shaft is adapted to be connected to a machine for pulling the tool through the pipe while rotating the tool such that the cutting elements on the reamer head remove debris from the inside wall of the pipe. The legs center and stabilize the reamer head to prevent contact with the internal pipe wall during the cleaning operation. Water or other lubricating fluid is ejected from the shaft during use of the tool to lubricate the tool in the pipe, and to flush loose debris out of the path of the tool.Type: GrantFiled: January 3, 2019Date of Patent: September 29, 2020Inventor: Ted R. Dimitroff

Patent number: 10557587Abstract: A tool with a rotatable guide head and a rotatable reamer head is pulled through old asbestos-containing pipe to break up the pipe. Liquid is supplied through a shaft between the guide head and reamer head so as to form a slurry mixture with the broken pipe. The slurry is removed through vertical bored relief holes. A drying compound is added to the slurry, which then hardens for easy disposal of the solidified waste material.Type: GrantFiled: October 16, 2018Date of Patent: February 11, 2020Inventor: Ted R. Dimitroff

Patent number: 8641326Abstract: An improved method for replacing existing underground sewer pipe is accomplished without excavation, pipe bursting, or pipe reaming. First, vertical sight holes are drilled into the ground and through the existing pipe. Slurry material from the vertical hole drilling fills the old pipe. Then, a pilot hole is drilled in a first direction through the old pipe. Then, a reaming tool is pulled in the opposite direction so as to enlarge the pilot hole and grind out the old pipe, while simultaneously pulling the new pipe into position behind the reaming tool. The broken old pipe and slurry are vacuumed out of the vertical relief holes.Type: GrantFiled: February 10, 2012Date of Patent: February 4, 2014Inventor: Ted R. Dimitroff

Patent number: 8365841Abstract: An improved back reamer for horizontal directional drilling is provided with multiple components which can be assembled and disassembled before and after the back reaming process. The reamer includes a main shaft connectable to the drill string, a reamer head removably mounted on the main shaft, and a pull tab removably attached to the main shaft. Faceted couplings between the reamer shaft and head, and between the reamer head and pull tab preclude rotation between the components.Type: GrantFiled: March 2, 2009Date of Patent: February 5, 2013Inventor: Ted R.

Publication number: 20110299941Abstract: A soil shoring method is provided wherein a pilot hole is drilled into the soil to a desired depth. A cutting tool is then used to cut an elongated trench or slot in the soil at the desired depth and in a desired configuration. During the drilling and cutting processes, a slurry is preferably provided into the hole and the slot to help support the walls of the hole and slot. After the cutting tool is removed from this slot, shoring plates are inserted into the slot. Then, soil on one side of the plates is excavated, without any cave-in risk.Type: ApplicationFiled: June 6, 2011Publication date: December 8, 2011Inventor: Ted R. Dimitroff

Patent number: 7674072Abstract: Apparatus and method for connecting a lateral pipe to a main pipe are provided by a tool having a first end within the main pipe and a second end outside the lateral pipe so as to apply pressure to the below-ground connection of the main and lateral pipes from an above-ground location. The entire operation may be done without a person having to enter into an access opening in the ground to connect the lateral pipe to the main pipe. A laser is used to determine the depth of the access hole relative to the surface of the ground and the main sewer pipe.Type: GrantFiled: March 9, 2006Date of Patent: March 9, 2010Inventors: William E. Shook, Ted R. Dimitroff

Publication number: 20090250266Abstract: An improved back reamer for horizontal directional drilling is provided with multiple components which can be quickly and easily assembled and disassembled before and after the back reaming process. The reamer includes a main shaft connectable to the drill string, a reamer head removably mounted on the main shaft, and a pull tab removably attached to the main shaft. The components are much lighter than prior art one-piece reamers, and thus improves safety to the installer and operator during the horizontal drilling operation.Type: ApplicationFiled: March 2, 2009Publication date: October 8, 2009Inventor: TED R. DIMITROFF

Patent number: 7581600Abstract: An improved method of forming a trenchless flow line is provided. The method includes support of the boring tool at each sight relief hole using a hook extending downwardly into the hole so as to overcome the force of gravity on the tool during the pilot hole drilling step. Then, a back reaming tool is connected to the end of the boring tool, and the pipe is connected to the reaming tool, such that the reaming tool reams the pilot hole to a larger diameter ahead of the pipe, which is pulled through the hole with the reaming tool. Drilling fluid is supplied during the reaming process to form a slurry which is pushed ahead of the pipe and upwardly into the sight relief holes, as the pipe is pulled through the reamed hole.Type: GrantFiled: June 6, 2006Date of Patent: September 1, 2009Inventor: Ted R. Dimitroff
