What Does Horizontal Earth Boring Mean?
Horizontal auger boring refers to the use of auger boring machines to prepare holes by the installation of a casing whereby the spoil is removed by the use of augers. Horizontal earth boring is a trenchless construction process whereby a bore is formed underground, which is filled by casings that are jacked into position behind the cutting head. Horizontal earth boring is used to lay piping or utilities underground without opening a trench.
Horizontal earth boring is also referred to as auger boring.
Trenchlesspedia Explains Horizontal Earth Boring
In horizontal auger boring, a cutting head creates the bore, while an auger removes the spoil that is generated. Casings are jacked into position as the bore is being drilled. Hydraulic jacks are used to push the casings into position. Either an entry pit or drive shaft is used as the starting point for the drilling operation, and as the base for the hydraulic jacks. Either the exit pit or the receiving shaft may be used as the ending point. Spoil is removed from the entry pit after being deposited by the auger.
