Abstract
A method for creating a weep hole is disclosed. The weep hole is drilled in an uncured, concrete, hollow core structural component having one or more external surfaces and one or more internal surfaces. The weep hole is drilled using a drilling apparatus comprising a drill, a rotating drill bit with an internal fluid passageway, a power source, and a pressurized fluid source. Loose, uncured concrete material deposited near the weep hole on the one or more internal surface as a result of drilling the weep hole is removed by releasing pressurized fluid which flows from the pressurized fluid source, through the drill and the rotating drill bit.
Claims13
A method, comprising:
- drilling a weep hole in an uncured, concrete, hollow core structural component, the hollow core structural component having one or more external surfaces and an internal surface, using a drilling apparatus comprising:
- a drill;
- a rotating drill bit with an internal fluid passageway;
- a power source;
- and a pressurized fluid source such that loose, uncured concrete material is deposited near the weep hole in an amount and configuration sufficient to interfere with the operation of the weep hole;
- repositioning the drill bit so that a fluid outlet is proximate to the internal surface;
- and
- removing the loose, uncured concrete material deposited near the weep hole on the internal surface as a result of drilling the weep hole by directing a flow of pressurized fluid which flows from the pressurized fluid source, through the drill and the rotating drill bit, and through the fluid outlet.
A method comprising:
- positioning a drill bit in a weep hole of a hollow core structural component having an internal surface, the drill bit having an internal fluid passageway and one or more fluid outlets, wherein the internal fluid passageway and the one or more fluid outlets are connected such that a pressurized fluid can flow through the drill bit and exit at the one or more fluid outlets;
- repositioning the drill bit so that the one or more fluid outlets is proximate to the internal surface;
- and
- removing material debris that is proximate to the weep hole by releasing the pressurized fluid which flows through the internal fluid passageway and exits the one or more fluid outlets while the drill bit is rotated about a longitudinal axis.
A method comprising:
- drilling a weep hole in a hollow core structural component with a drill bit creating material debris adjacent to the weep hole, the hollow core structural component having an internal surface;
- repositioning the drill bit so that a fluid outlet within the drill bit is proximate to the internal surface;
- and
- directing a flow of pressurized fluid adjacent to the drill bit to remove the material debris from adjacent the weep hole.
