Box culvert installation clamps - Entrants - Bill Goertzen (Drain. Fore.), Don Schulz & Joe Clouatre (Shop Welders) Cost - $900.00 These clamps came about from a process of trying to find a better way to tighten the joints for large box culvert installations, the weight and bulk of the sections has always made for difficulties in getting even pressure when fitting the sections together. Typically an excavator has been used to push on the open end as the crane lowers the section into place, but this has never provided a completely tight fit. Bill Goertzen has been trying different methods using comealongs to help guide the sections into place. Through these endeavors he envisioned a clamp that could be attached to the boxes and allow for attachment points for the comealong. Bill approached, Don and Joe and they put their heads together and came up with the clamps shown in the pictures. These clamps are put on the ends of the side walls on both sides of the box sections and then two comealongs are strung between them on the inside of the boxes, allowing the installers to put even pressure on both sides as the box is maneuvered into place, the clamps are simply moved to the end of each new section and the comealongs are extended. This has proven to be very effective on the first project we used them on this spring. We had a storm damaged crossing and it was upgraded to box sections. The supplier (LC&T) visited the site during the installation and have provided a letter (see attached) stating that it was the best installation of their product that they have seen. Once again due to
their ingenuity and the desire to do the job to the best of their abilities,
Bill, Don and Joe have provided a solution for perfecting an installation
practice, giving us the best product possible. |
