Vibratory Ploughing
Distribution of utility services is accomplished using two general systems: Overhead and underground. Gas, Water and Sewer have historically used the underground technique. Telephone, Cable TV, Electrical Services, and now Fibre Optics are often being specified for underground installation. This trend is due to the development of new materials and technology in cable types and construction as well as the obvious protection from the elements.
Installing underground utilities has been done by either trenching or cutting into soil with a kind of ripper blade known as ploughing. Early ploughing of cable was accomplished by pulling a ripper blade with a cable laying section on the back through the ground using brute force. This often required connecting several crawler tractors together to get enough of draw pull. This configuration often tore up the work site and required substantial restoration in addition to involving multiple pieces of equipment. However, this method was usually more economical than opening a trench, installing the utility, and restoring to original site condition.
In the past 10-12 years the method of applying vibration to the ripper blade has become more advantageous. By shaking the blade, usually up and down, the soil will cut easier thus requiring less force to pull the blade.
wahey ,sligo! what a coincidence!,used to live there,about to use the same method to put 355 diameter poly pipe in henley beach in adelaide !
