Road Crossing

The 25 Tonnes Pilot Tube Microtunneling bored a 225 mm diameter PVC pipe, 12 m long under a road in Armadale, Western Australia, without any traffic disruption.

Westscope Contracting complete the job in less than 2 days with a small crew of 2 people, significantly reducing the labor cost.

The Pilot Tube Microtunneling B250 has enough power to handle most applications in most ground conditions.

Perth and its suburban area is located on the West Coast of Australia which is predominantly sandy however the Armadale area is located in clay country and therefore the works were undertaken in a soft yellow clay, which proved not problem for the B250 Micro Tunneler.

Westscope Contracting have been using their B250 Pilot Tube Micro Tunneller machine for a few years now and have installed over 3.4Km of sewer pipe using this system and the machine has never let them down.

Troubleshooting Guide From a Real Pipe Bursting Contractor

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.

Method No 3 – We have also used a stick welder to run a series of beads across the item to make it brittle and that worked too. The Mole was able to crack it but the trick is to get the welds down around the halfway mark on both sides, otherwise the ring will still grab the mole body, not as tight but enough to be a slight worry.

I have read of fellows in Britain using acid to free a stuck mole, but I reckon that would have to be a last resort.

I hope this isn’t too outdated, but if it helps someone out of a bind someday then why not.

    B110 Small Microtunneler with Real Grunt

    Typically 150mm sewer pipe is installed to grades of 1/200. In good sandy ground conditions this machine has achieved bores in excess of 40m in length and to millimetre accuracy. Generally the machine is operated from inside a standard backhoe trenching box, however timber sets to 3.5m deep and steel caisson shafts have also proved very successful.

      5 reasons to replace a sewer line

      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.

      Reason 2 : “Root Penetration”
      This is a huge problem and there is much ongoing work required to keep the roots in check.  Why not just get rid of the problem once and for all and replace the pipe with Poly using pipe bursting.

      Reason 3 : “Collapsed Main”
      Not an uncommon problem and can happen for many reasons. This sort of failure is a great cause of infiltration and ex-filtration causing pollution to surrounding waterways.

      Reason 4 : “Cracking”
      To avoid bigger leaks and before the main line collapse, replacing the pipe as soon as you detect cracks is always a good idea.

      Reason 5 : “Offset Joints”
      Due to ground settlement, landslide, tree roots and poor bedding during installation, the main line can suffer from this weakness and therefore generate massive leaks.

      What are the choices you have to face these major problems ?
      There are a few choices you can utilise to fix some of the above problems,
      – Open Cut Method
      – Relining
      – Pipe Bursting

      But I believe that in small pipelines like this one, the best and most cost effective ways to fix the problem is by using pipe bursting.

        New B750 Pilot Tube Microtunneler

        The latest release of the Pilot Tube Microtunneler B750, a 50T push microtunneler. The perfect machine for installing sewer lines up to 400mm diameter.

        The new machine will be going to work in the Perth region where it will be primarily used on Infill sewer and land development projects.

        We have redesigned the B750 upon receiving feedback from our customers for a bigger and more powerful machine and the new rig includes a much stronger thrust box which can handle much greater loads than before.

        The power pack has also been upgraded to provide increased production and faster turnaround on the job.

        Overall the new B750 keeps the same philosophy of a strong reliable microtunneler which is both simple to operate and maintain.

        The footprint of the drill has not changed and can still be set up in a standard shoring box or caisson with a minimum size of just 2.4m

        More information on the B750, visit the page here.

        360 degree view of the new B750 Micro Tunnelling machine

        A 50T push microtunneler which will drill straight lines of 400mm sewer up to 80m long. No Dig Equipment design team is proud to show you a 360 degre view of the latest and the strongest ever build 50T pilot tube microtunneling machine. The essential machine for gravity sewer installation and other microtunneling jobs.

        It is proven that it will be more accurate and will drill longer shot than the other big micro tunneling machine in its category, like Akkerman TBMs or Auger Boring machines.

        Stronger and more accurate than ever before

        The B750 pilot tube Micro Tunnelling Boring Machine, so called MTBM, with 50 tonnes of pushing forces is able to install pipes of up to 450mm outside diameter and with incredible accuracy. Ideal for gravity sewer and other straight pipelines. The large inner diameter of the drill rods greatly help the vision of the lights for the theodolite guidance at long distances. Because you naturally have to correct the constant derivation of the drill head, the bigger is the inner diameter size of the drill rods, the better is the vision of the lights, helping you to drill longer shot and more straight than other hudge microtunneling and auger boring machines.

        The 50T B750 is an extremly good value for money

        Because of the small size of the rods, there is a lot less front resistance and therefore needs a lots less pushing forces to drill through.

        Less resistance forces means :

        • less power required
        • smaller hydraulic pump (much cheaper to maintain)
        • smaller power pack means smaller engines (easier to maintain and will produce the same outcome)
        • overall less petrol or diesel consumptions
        • less and smaller hydraulic hoses to deal with (those reinforced hoses can be very heavy)

        Smaller gear package means lighter to carry and more compact

        Therefore, you would need smaller trucks and smaller excavator or digger to carry the machine to site. A little 3T excavator is usually the best advantage because it is a lot less environmentally destructive than the other big 20T diggers.

        Its ‘naked’ look will save you money

        The overall look of the new Pilot Tube Microtunneling B750 is voluntarly ‘naked’. Those machines have to deal with harsh environments and are very often cover of mud at the end of the job. Making it easy to clean will saves you time and therefore money in the long run. The failures will be easier to spot too. Any leak or damaged hose will be much easier and much faster to replace bringing the maintenance cost down to a minimum.

          Training for Ground Water Control on the new B750

          Ground Water Control has taken delivery of the new B750 Pilot Tube Microtunnelling machine from NO DIG Equipment.

          Here is their first job with the microtunneler, which proved the perfect training situation to demonstrate the machines capabilities.

          The bore was for a 150mm sewer line across a quiet suburban road.  The line was 2.7m deep and 1.5m below the ground water table.  The length of the bore was 18m to grade and line and proved to be an easy test for the B750.

          This was a perfect job for Ground Water Control, as the job involved both drilling and lowering of the ground water table.

          There expertese and years of experience in groundwater controll and management made this an ideal job for them to cut there teeth.

          Both bore and receival pits were dewatered using their silenced 6″ diesel pumps and well pointing to lower the water table to below the existing sewer line.

          Once the water was under control, the microtunneller was set up to line and grade and the 150mm PVC boring pipe was installed to within millimetre accuracy.  The whole operation including the installation of pits, well point dewatering and microtunneling of the sewer took less than 3 days and proved to be a great success.

          Another successful job completed by Ground Water Control, thanks to their new acquisition, a Pilot Tube Microtunneling B750 with 50T Push and 3500Nm of Torque.

          A 360 degree view of the B750 Micro Tunneler 2012 model here.
