Over time, this method of hand rodding can become inefficient and counterproductive. “Knowing the exact footage, we can then send in a footage-marked hand rod with hooks from the other side to catch the snares on the PDRP.”. Because many manholes are full of water when first opened, they need to be pumped out before Hellman’s crews can begin working in them. 1. “When we were hand rodding, our performance degraded quickly beyond 300 feet of duct,” Haus recalled. Case Studies in Construction Materials provides a forum for the rapid publication of short, structured Case Studies on construction materials and related Short Communications, specialising in actual case studies involving real construction projects. PoE demarcation points are shallow installations where manholes and underground ducts are installed closer to street level. Its maximum performance distance is about 600 feet (in occupied duct), Hellman often deploys traditional hand rodders along with the PDRP rod when working in very long sections. “Even the force of a garbage truck dropping a trash dumpster on the pavement can cause a PoE duct beneath it to collapse,” said Haus. Previous case study Insight Enterprises. When compared to traditional hand rod wire fishing practices (where more human muscle is necessary), fewer hands would be required as the entire process would be achieved with the use of a powerful hydraulic pump and the push of a lever. These non-conductive rods are used for guiding (or fishing) wire or cable through ducts, walls, attics, crawl spaces, etc. With a power and telecom cable infrastructure for a city the size of New York and its boroughs, it’s no wonder ducts in underground networks become over crowded. 0000005579 00000 n Haus likes the adaptability and convenience of the PDRPs.
