No Dig Equipment

Here is some info sent in from a pipe bursting contractor who has obviously encountered some problems in the past.  It demonstrates some interesting solutions, so we thought we would pass it on to anyone who is interested.

"As we all learn, it is near impossible to crack through the old fashioned malleable cast iron items that can be encountered at times. We found several ways of dealing with these.

We sometime used a self propelled post hole digger and used that to bore down to the problem item.

Method No 1 - Call the nearest industrial gas suppliers, B.O.C had a mobile service in Brisbane, and a quick hit with a slug of liquid nitrogen will crack the iron ring item.

Method No 2 - Try the head down with an oxy torch method to cut the mongrel out and it works too but not easy. Difficult to prevent splatter getting on the mole body.

The Limestone conditions in Spearwood proved to be of little concern for the Rockman Microtunneler.  Rockmans specialised rock drilling system was utilised to install a 400 diameter steel sleeve as a carrier pipe for DN150 sewer pipe.  As the sewer was a gravity line, it had to be installed to exacting position in order to piece up to an existing line laid down stream at a grade of 1/240.

The drive was just 50m long, but due to the vicinity of some major underground services crossing the path of the sewer line, a trenchless solution was proposed.  The services crossing the sewer included a large Asbestos water main, high pressure gas main and fiber optic cables.

New Town Toyota Victoria Park (Jan 2009)

New Towns expanding business had the requirement for some additional car servicing space. So when the opportunity came to acquire the Newspaper premises next door, they knew there was some work required in converting the old news paper house into a modern Toyota Service Center.

In order to facilitate the the wash down requirements of the new service center, a trenchless solution was sought to keep disruption and cost to a minimum.

The job required installation of approximately 140m of sub slab gravity drainage pipe in order to hook up a series of sumps for washing down the shop floor.  The propposed gravity drainage lines discharged to the outside of the building where the contaminated effluent was first treated prior to discharge into the public sewerage system.

Due to the sloping site, depths below the slab where up to 2.2m deep.

Trenchless Australasia — September 2009

Horizontal directional drilling specialist Orpheus Contracting Pty Ltd has successfully completed several installations at Challenge Sports Stadium, located in Perth, for BGC Construction.

No Dig Equipment manufactures a range of Microtunneling equipment capable of installing pipe sizes from 150mm to 350mm in diameter. The move into the trenchless market was largely encouraged by the 10 year ‘Infill Sewerage’ project, instigated by the WA Water Corporation. The machinary was speciffically designed to cater for the installation of 150 and 225 diameter PVC sewer pipe, which are the most common sizes used in this project.

Our companies B110 microtunneler was specifically designed to be man handled into places which would normally be inaccessible by conventional construction equipment. The equipment is so small that it can fit through a standard household door. This means that it is possible to utilise this machine with a minimum of disruption to housholders and their properties.

The B110 is lightweight, high powered machine, which is capable of 11T of thrust force and 1,400Nm of torque. This is coupled to a petrol or diesel hydraulic power pack, capable of delivering70 L/m at 2500PSI pressure.

Need to empty a sump, vault, septic system, trench or mud-pit quickly with minimum fuss and maximum efficiency? Look no further than Sandguzzler!

Simple to operate, yet tough as nails, the Sandguzzler range of mud pumps are capable of moving viscous and abrasive fluids in almost any operating environment.  Depending on the application the Sandguzzler can employ cast steel, aluminum and polyurethane deep impeller vanes to produce a large discharge capacity coupled with a large volume discharge opening for passing water, liquid sands, muds and flow-able fill composed of stones and debris without clogging harming pump components.The Sandguzzler pumps are of the self-priming and self-burping centrifugal type.  They can be operated by hydraulic drives, meaning they can be deployed using a bobcat

Our Company sells a range of horizontal boring equipment, which may help increase productivity and provide considerable cost saving on your next contract.

The Aussie Mole is a pneumatic earth-boring tool which is ideally suited for installing cables and ducts from 20 mm through to 120mm in diameter.

These moles feature new state of the art technology, including a unique ‘floating head’ design. This provides more rapid penetration and increased accuracy in even the toughest conditions. This means that you will achieve increased productivity and thereby save money.

The Hanlyma HL518B directional drill provides the HDD operator with a powerful, practical, low cost alternative to the complex, computer-controlled machines commonly in use today. The benefits of this approach are significant - operating techniques are easily learnt, maintenance costs are minimised and downtime for repairs is minimized.

The robust hydraulic system is uncomplicated and generally trouble-free and the simple electrical circuitry ensures low-cost repairs – whether in the workshop or on site. Strategically located proximity switches prevent accidental damage to machine parts through incorrect operation.  Hanlyma drills incorporate a massive 100 KW Deutz turbo diesel engine, which diesel provides trouble-free starting and all the power needed.

This compact (8 tonne) unit combines a pullback capacity of 18 tonnes and is suppiel  with 153m of rod length.  Drill rods are forged one pice rods which provide the best option for directional drilling.

No Dig Equipment can supply a range of Iseki slurry microtunneling machines from sizes ranging from 250 throught to 600mm diameter.

Additional equipment including desandman Shaker, 150T pipe Jacks, bentonite mixing system, cables and slurry lines are available.
