Horizontal Directional Drilling - Bore Hole Reaming
This is the next step in the HDD process. As the pilot drill bit and survey probe reaches at the exit pit, the drill rods are connected with reamer. The reamers are pulled back to excavate soil and rocks from the bore hole. Water – Bentonite Mixture is used for drilling the hole, support the expanded hole, remove soil from the drilling site and cool the drilling components as well. The objective is to achieve predefined bore hole diameter, as per the requirement of the project. Bluegrass Technologies has successfully performed bore hole reaming tasks at unimaginably difficult terrains such as Bhivpuri Ghat and Shastri River in India.
