Auger Boring

What is Auger Boring

Perforator PBA 85 Auger BoringThis boring technique utilizes a steel casing, auger and a reaming head to excavate and remove the boring spoils. 

As the reaming head excavates the bore hole, the casing and auger transport cuttings from the face of the bore to the boring shaft.

This method of boring is the preferred construction method of Railroad Owners and many DOT’s.

Auger Boring is also known as “Dry Boring”.

The powerful and compact multi-purpose thrust boring machines are designed for steered and non-steered trenchless installation of underground service pipes.

They can be efficiently adapted to all current drilling methods, with different drilling tools and the appropriate equipment application is possible in all soil classes.

Perforator PBA 85 in Round Shaft Auger BoringOur Optic Electronic Navigation System (OEN) provides for the exact steering of the pilot rods and ensures that the required tolerances are kept.

With proper extension frames all pipe lengths can be laid and achieve drilling lengths up to 80m in suitable ground conditions.




Advantages of Auger Boring

 Accurate installations +/- 25mm over distances up to 100 metres between pits

  • Can operate from shafts as small as 2.40mØ

  • Ideal for gravity drainage pipes, cable ducts or accurate installations

  • Can install variety of pipe materials, such as clay, steel, PE, concrete or GRP

  • Dry method of installation - unlike micro tunnelling does not generate slurry

  • Auger boring is unaffected by surface obstacles

  • No disruption to surface, buildings, road, river, rail or traffic

  • By boring underground the working area is confined to entry and exit points

  • Unlike micro tunnelling, Guided Auger can be retracted back to the working pit

  • Can be used to install pipes in changeable ground conditions

  • Auger boring is quick and in many cases has lower overall costs

Flowtek have just completed a rock drill for Scottish and Southern Energy under the A417 Dual Carriageway to install a 225mm and 125mm in a dual drill . The ground consisted of limestone, mudstone medium to strong and forest marble with fracture surfaces. Flowtek used the services of Clear Solutions Limited to undertake a full investigation of the borehole information for the correct additives for the A417 Dual Carriageway crossing and two stream crossings. Flowtek utilised Environmental drilling additives to undertake the stream crossing.

Flowtek utilised the Vermeer D36x50 for the reaming process but for the A417 dual carriageway crossing we utilised our Ditch Witch All Terrain JT30

Flowtek have recently had the opportunity to work for Bailey Construction to install an electric ducting right on our doorstep at Whealty Hall Road Doncaster.
