Due to the logistic constraints and limited head room allowances, micro piles were envisaged for the captioned project, I.e.,The Supply, Installation, Testing & Commissioning of Gas Insulated Line (GIL) Between 400 KV GIS at DREP and Step up Transformer at K-III and Associated Modification Works in Jebel Ali.<\/p>\n\n\n\n

Methodology<\/p>\n\n\n\n

Drilling was performed by Swissboring by rotary drilling methods using bio-degradable polymer mud as the flushing medium.<\/strong><\/p>\n\n\n\n

Since there were limitation head room tolerance small drill rigs were employed for the construction of micro piles.<\/p>\n<\/div><\/div>\n\n\n
