Abstract
Systems and methods for forming a channel in an uncured concrete slab are described. The system includes a first blade, a second blade, and a third blade. The first and second blades are oriented vertically relative to the concrete slab and spaced a predetermined distance apart. The third blade is positioned between the first blade and the second blade to form a concrete-receiving interior. The system also includes a conveyer having fin(s) extending therefrom to move material through a chute. The first, second, and third blades are configured to cut the channel in the concrete slab and direct excess concrete into the chute where the conveyer moves the excess concrete out of and away from the channel.

A system for forming a channel in an uncured concrete slab, comprising:
- a first rotatable blade and a second rotatable blade, the first and second rotatable blades spaced a predetermined distance apart and oriented vertically relative to the uncured concrete slab;
- a third blade positioned between the first rotatable blade and the second rotatable blade and oriented horizontally relative to the uncured concrete slab, wherein the first rotatable blade, the second rotatable blade, and the third blade cooperate to form a concrete-receiving interior, such that when the system is translated across the uncured concrete slab and the first and second rotatable blades are rotated, a channel is cut into the uncured concrete slab and concrete cuttings move through the concrete-receiving interior;
- a chute positioned to receive the concrete cuttings from the concrete-receiving interior;
- and
- a conveyer having one or more fins extending therefrom, the conveyer and the one or more fins arranged to move the concrete cuttings through the chute away from the channel.
A method for forming a channel in an uncured concrete slab, comprising:
- positioning a cutting unit proximate to the uncured concrete slab, the cutting unit comprising:
- a first rotatable blade and a second rotatable blade, the first and second rotatable blades spaced a predetermined distance apart and oriented vertically relative to the uncured concrete slab;
- a third blade positioned between the first rotatable blade and the second rotatable blade and oriented horizontally relative to the uncured concrete slab, wherein the first rotatable blade, the second rotatable blade, and the third blade cooperate to form a concrete-receiving interior,
- a chute positioned proximate to the concrete-receiving interior;
- and
- a conveyer having one or more fins extending therefrom;
- and
- translating the cutting unit across the uncured concrete slab while rotating the first rotatable blade and the second rotatable blade, such that a channel is cut into the uncured concrete slab and concrete cuttings move through the concrete-receiving interior into the chute, and the one or more fins of the conveyer move the concrete cuttings through the chute away from the channel.
A system, comprising:
- an uncured concrete slab;
- a rail system positioned adjacent to the uncured concrete slab;
- and
- a channel cutting system supported by the rail system, the channel cutting system comprising:
- a frame engaging the rail system;
- and
- a cutting unit supported by the frame, the cutting unit comprising:
- a first rotatable blade and a second rotatable blade, the first and second rotatable blades spaced a predetermined distance apart and oriented vertically relative to the uncured concrete slab;
- and
- a third blade positioned between the first rotatable blade and the second rotatable blade and oriented horizontally relative to the uncured concrete slab, wherein the first rotatable blade, the second rotatable blade, and the third blade cooperate to form a concrete-receiving interior, such that when the system is translated across the uncured concrete slab and the first and second rotatable blades are rotated, a channel is cut into the uncured concrete slab and concrete cuttings move through the concrete-receiving interior.
