Building a new residential house always involve a lot of preparation work including installing the underground services before digging for the foundations : Gas, Water, Sewer pipelines and Telecommunications Cables. and drainage.

Garbut Drainage Contractors was contracted to install a drainage house connection. The problem for Garbut Drainage was that the main line was at the other side of the road making the installation a lot more difficult.

Since the local Shire does not permit open excavation across its existing road network, Garbut Drainage had to find another solution, instead of breaking the road, blocking the traffic and spend thousands of dollars in reinstatement and traffic management.

Therefore they choose a Trenchless solution which was safer, faster and without traffic disruption.

Garbut drainage engaged Westscope Contracting, who used a B250 Pilot Tube Microtunneling machine from No Dig Equipment to carry out the job.

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.

Here are some great photos which show 5 common reasons of a typical deteriorating sewerage system.

These photos on the left show some typical problems of the old earthenware pipe and are classic cases for renewal by pipe bursting.

Reason 1 : "Hammer Taps"
Here a junction collapses and falls into the pipe, this will generate some major problems in the main line as well as the house connection.

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.
