HDD performed at Guam Intl Airport Runway
HDD Performed at Hotel Royal Orchid, Guam
HDD is a steerable trenchless method of installing the UG Utilities along a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. We propose to utilize this method for the Road crossings on Route 1. HDD is capable of installing pipes upto 2000 M.
The process starts with receiving hole and entrance pits. These pits will allow the drilling fluid to be collected and reclaimed to reduce costs and prevent waste. The first stage drills a pilot hole on the designed path, and the second stage (reaming) enlarges the hole by passing a larger cutting tool known as the back reamer. The reamer's diameter depends on the size of the pipe to be pulled back through the bore hole. The driller increases the diameter according to the outer diameter of the waterline to achieve optimal production. The third stage places the product or casing pipe in the enlarged hole by way of the drill stem; it is pulled behind the reamer to allow centering of the pipe in the newly reamed path.
Horizontal directional drilling is done with the help of a viscous fluid known as drilling fluid. It is a mixture of water and, usually, bentonite or polymer continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe. The drilling fluid is sent into a machine called a reclaimer which removes the drill cuttings and maintains the proper viscosity of the fluid. Drilling fluids hold the cuttings in suspension to prevent them from clogging the bore. A clogged bore creates back pressure on the cutting head, slowing production. All work will be performed in accordance with OSHA & EM 385 1-1 with the application of local & federal laws. There are no harmful impacts on the environment with the use of HDD.
ICC introduced HDD to Guam and has a lot of experience and qualified operators to perform HDD. From Past Experience in dealing with Federal Highways & Govt of Guam, it is determined that HDD is the preferred method of crossing a new UG Utilities along major roadways & highways
We guarantee HDD will save you time and money.
