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 new fence for the Perth International Airport Control Tower

          New security fencing around the Perth International Airport Control Tower

          When it came to installing new security fencing around the Perth International Airport Control Tower, DBS Fencing called on No Dig Hire to supply vacuum excavation equipment to install the foundations for the new fence posts.

          Due to the great number of critical underground services running to the Control Tower, mechanical excavation for the installation of the fence posts was not an option. Severing just one of the many fibre optic cables, running to the complex, would cause catastrophic consequences to the airport and airline passengers. For this reason hand excavation in all areas was specified.

          Hand excavation in areas where no services were entering the control tower complex seemed a viable solution at first, however once the crew started digging they found that the extent of tree roots in the excavation hampered progress significantly.

           So, in order to speed up the process, a VM450 trailer mounted vacuum excavator from No Dig Equipment was utilised. After a short training session the crew from DBS Fencing was up and running and installing fence holes at three times the rate, compared to manual excavation.

          In critical areas, where underground services crossed into the compound and potentially clashed with the fence foundation, the vacuum excavator proved invaluable. The ability of the VM450 to safely remove dirt around live services meant that there was no risk of damaging existing pipes and cables. Cables and ducts could potentially have been damaged, even by hand excavation, where a sharp shovel blade could easily slice through a duct, live power or fibre optic cable.

          The vacuum excavator definitely proved it’s worth, being particularly useful around critical infrastructure, exposing tree roots and enabling them to be cut away in a safe, controlled and environmentally friendly manner.

          Contact us today to hire a Vacuum Excavator VM450 on trailer.

          Diesel and Petrol powered units available.

          Piston VS Screw Compressors

          Piston VS Screw Compressors

          Introduction

          Choosing the right compressor for your soil displacement hammer is a crucial step. We’ve highlighted the main differences between the 2 most common type of compressor, piston vs screw, and show you why you should choose one instead of the other.

          The piston / reciprocating compressor

          Piston compressors or reciprocating compressors are still the most common type found across all industries due to their relative low cost. An engine, petrol or diesel, drives an air compression unit via belt. The principle of this air compression unit is very similar to the internal combustion engine that’s in your car. As it spins, the ambient air is sucked in the piston chambers, compressed and expelled to the air tank using a system of tuned cams and valves. Therefore it involves a lot of wear and tear down the track due to friction and operation heat which means more oil carry-over and more maintenance cost.

          The oil carry-over effect is when the pistons, cylinder, valves, etc wear, the oil in the crank case gets pass the piston rings and is carried over in the air line making a poor air quality. This “normal” wear and tear decrease the efficiency over time, increase the maintenance schedules and therefore the running cost.

          The rotary screw compressor

          These units are usually sound proofed and Diesel powered making the initial cost higher than piston compressors. The screws are driven directly by the engine making a more rigid unit. the screws have special shape, one ‘male’ and one ‘female’ compressing the incoming air at a smooth and pulse-free pace. No need for storage tank, the air is delivered constantly at every stage. The rotary screw compressors are fluid cooled which provide many advantages :

          • it lubricates the bearings
          • cleans the air (better air quality means a longer air tool life)
          • create a non-wearing seal between the screws and the casing (meaning lower maintenance cost down the track and always very efficient)
          • cool the compressed air down significantly and easily

          Piston compressors have usually internal working temperature of about 200°C compare to 70~80°C for screw compressors.

          A cooler operation temperature means a much easier way to cool, remove the moisture and clean the outlet air. Again, screw compressors will deliver a much better quality air and will therefore contribute to the life of your air tools.

          IMPORTANT : The duty cycle

          A rotary screw compressor has a 100% allowable duty cycle and operate continuously if the need arises.

          Piston compressors operate intermittently in order to cool down between 2 tank fill. They have an allowable duty cycle of about 60 to 70%. For this reason, they need to be oversized to compensate their periodical ‘shut-down’. Even with large storage tank, the lack of constant compressed air can be a problem for the good operation of a soil displacement hammer. The soil displacement hammer can lock itself in the ground if there is not enough air to keep the piston hitting the barrel. That’s one of the reasons why we recommend screw type compressor to use with our Soil Displacement Hammer NODIG Mole.

          Cost & maintenance

          As said earlier, the piston compressors have low initial costs but high maintenance cost. knowing that you need to oversize it to suit your need. Not only that, but poor air quality will damage your air tools and/or will slow your operations down when the compressor needs repairing. Your air tools will also need more maintenance or replacing. All this contribute to a higher cost down the track.

          As opposed, a screw type compressor has a higher initial cost but lower maintenance cost (over the years) and will deliver a good quality air which is crucial for the long life of your air tools. It will also keep your crew working as the clean air will be available when they need it. These compressors do not need to be oversized to compensate for limited duty cycle and are more efficient. For example, a 7.5Hp rotary will do the job of a 10Hp piston. Less energy is required and therefore operating cost reduced.

          Recommended compressor for a soil displacement hammer

          We recommend the rotary screw DENYO DIS-55LB compressor for our NODIG Mole ranging from 45mm diameter to 76mm diameter. It can be easily carried on the back of a ute. It is perfectly suited for any NBN, fiber optic installation work.

          Even if you need less air for the NODIG Mole 45mm for example, having a bigger compressor can only be beneficial. It will allow you to use it with many other air tools such as a jackhammer for example, in order to break out a bit of concrete or rock when digging the launching pit. The NODIG Mole will only take the air volume it can take and the screw compressor will adjust itself automatically, using flow control valves.

          DENYO is a very well known, high quality Japanese compressor brand, reputed for their reliability and sturdiness over the years.
