Abstract
Systems and methods for the continuous slip form construction of concrete barriers over support cages. A tube feeder of a slip form construction system can include angled tubes that can direct reinforcing bars into a concrete barrier and also provide space between the tubes for insertion of a support cage through the system and into the concrete barrier.
Claims11
A tube feeder for use with a system for slip-form construction of a concrete barrier, said tube feeder comprising:
- a tube feeder frame configured to be positioned adjacent a hopper of a slip form construction machine, the tube feeder having a front, a back, and a bottom;
- a first pair of tubes passing through the frame, each tube of the first pair at approximately a first height from the bottom and configured to receive a reinforcing bar at a front end of the tube and to direct the reinforcing bar out of the tube at a back end of the tube and into a concrete construction produced by the slip form construction machine, wherein the tubes of the first pair are angled such that the front ends of the tubes are farther from each other than are the back ends of the tubes;
- and
- a second pair of tubes passing through the frame, each tube of the second pair at approximately a second height from the bottom and configured to receive a reinforcing bar at a front end of the tube and to direct the reinforcing bar out of the tube at a back end of the tube and into the concrete construction produced by the slip form construction machine, wherein the tubes of the second pair are angled such that the front ends of the tubes are farther from each other than are the back ends of the tubes.
