Underground Boring – A Great way of Drilling.

Underground Boring is a non invasive technique to install conduits underground that eventually be utilised for phone, gas, Television, electric or water supply. Originally directional drilling established by the oil industry in the United States, this specific strategy is these days broadly used for just about all pressure pipes underneath major obstacles such as freeways, large rivers, airport runways and so forth. A steerable drill bit of 90mm diameter is launched through the surface at 10′ -15′ and produces a pilot hole. This is followed by a 125mm washover pipe. Upon completion, the pilot string will be removed and a rotating barrel reamer travels back along the washover pipe. Subsequent reaming continues until finally the actual necessary diameter is obtained. Drives of more than one thousand metres and upward to one metre in diameter have been carried out.

Directional Drilling is done with the assistance of a viscous fluid known as drilling fluid. It is a combination of water and, commonly, bentonite or polymer continually pumped to the actual cutting head or drill bit to help facilitate the removal of cuttings, strengthen the bore hole, cool the cutting head, and lubricate the passage of the product pipe. Directional drilling requires the installation of a pilot rod directly into virgin ground, which is steered from above ground using a tracking device. The head of the pilot rod is eccentrically loaded, so that rotational steering will be able to take place.

Southern Cross Directional Drilling have a new addition with our brand new 32000 pound Astec HDD that has a new F2 location system. Naturally, trenchless pipe laying technologies provides several uses in addition to far reaching applications. Its not basically huge pipelines which are carried out by Southern Cross Directional Drilling. Smaller sized (blank) environmental services are some of the companys additional services.

For almost any job large or small, Southern Cross Directional Drilling has got the expertise and experience for getting the work accomplished promptly and inside of budget.
