Contractor drives micropile manufacturing with KLEMM toolsadmin
KLEMM rod dealing with attachment drives productiveness
KLEMM drilling rigs will be geared up with a MAG 7.0 Revolver, which is good for deep basis strategies like tiebacks or soil nails the place the casing is being reused. The KR 806-3G Technical Foundations rented on the Roanoke venture didn’t have a revolver since micropile casings are a one-time use. The HBR 120 rod dealing with attachment proved to be a greater match.
The drilling crew would drill a gap with the casing and the interior rod. The KR 806-3G operator would go away the casing in place and pull the interior rods. The HBR 120 was then used to seize the interior rod and feed it again into the following piece of casing.
“When the crew was prepared to begin drilling the following gap, they have been all able to go,” says Stoneman. “Having the casing and rods pre-loaded allowed them to drill at a sooner manufacturing price.”
The smoothness of the micropile drilling operation almost doubled productiveness in comparison with the contractor’s conventional methodology. Technical Foundations would historically use the winch to hoist the casing and interior rod and make the connection by hand. The contractor would sometimes obtain 6 to eight micropiles day by day with that methodology in comparison with the 14 it accomplished utilizing the KLEMM rod dealing with attachment.
“The rod handler holds the interior rod and casing nonetheless in order that we will make the connection to the drill head,” explains Stoneman. “The drilling rig operator can detach from each joints, then increase the pinnacle up, so it is a sooner transition so as to add the following piece of drill metal.”
The HBR 120 can match on any model of excavator, however Technical Foundations stored it mounted on a Komatsu. Mounting the attachment was easy. The contractor constructed an adapter that allowed the rod dealing with attachment to be simply mounted to the arm with pins and bolts. A piggyback system facilitated the connection of hydraulic hoses and electronics to the fuse block of the excavator. This allowed the operator to simply management the features of the rod dealing with attachment, together with rotating, tilting, and clamping casing and interior rods.
The HBR 120 can rotate on a 360-degree axis, however Technical Foundations didn’t require that degree of motion on this venture. The larger focus was getting the rod dealing with attachment and the drilling rig mast on the correct aircraft to maintain the casing correctly aligned so the sections would thread correctly.
This course of required cautious communication between a spotter and the drilling rig and excavator operators. The KLEMM drilling rig was operated by distant management so he had the flexibleness to maneuver right into a place with higher visibility. The spotter used hand signaling to assist each operators to correctly line up the joints.
