Trenchless Technology Tooling

 

The economical and ecological advantages of trenchless technologies compared with open trenching are obvious: Valuable surfaces are protected, time-consuming and expensive excavation and restoration work is not required, there are no traffic jams or diversions, only low emissions of noise, CO2 and particulate matter and the actual construction times are shortened significantly.

 

The Environment Benefits

Trenchless installation means: it is much safer, there is no surface damage, no disruption to residents or traffic flow and with minimal excavation work, less construction equipment/plant is required and noise and CO2 emissions are kept to a minimum.

Moling Equipment

Moling Equipment 

The mole – an animal known as clever, reliable and hard-working best represents the TRACTO-TECHNIK “TT” GRUNDOMAT soil displacement hammer, or at least Dipl-Ing. Paul Schmidt the company founder thought this to be so.

 Thus in 1970 the TT GRUNDOMAT mole started its triumphant parade around the globe and become very popular. The ‘little digger’ has an excellent reputation and 91% of respondents in the Trenchless Technology market were interviewed and were found to be familiar with the TT Mole. Therefore, it is hardly surprising that experts like referring to this technique of Trenchless drilling as Mole technology.

The benefits of Trenchless Moling

Moling technology is widely-used and ever increasing in the civil engineering fields .Compared to open-trenching this method of underground installation and renewal of supply and disposal pipelines has major technical and economic advantages. Shorter construction times are major advantages especially when providing property service connections like fibre installations or electrical cabling and when crossing busy roads.

 

 

GRUNDOMAT soil displacement technique

The pneumatically driven hammers work according to the soil displacement method, when moving forward the spoil is displaced into the surrounding soil. A channel is produced into which socket less short or long pipes up to OD 160 made of plastic (PE, PVC or PE-X) or cables can be pulled in. Depending on the type of soil, lengths of up to 25 m can either be pulled in simultaneously or later. A compressor with 6 – 7 bar operating pressure is required for this, with exact alignment of the machine towards the target necessary for high on-target accuracy.

The 2-Stroke Principle

With the proven 2-stroke principle, the precise target accuracy, as well as the exact alignment and adjustment are achieved through the 2-stroke impact method.

On the first stroke, the whole moving head assembly is propelled forward as the piston accelerates and impacts against the rear of the chisel driving it forward to create a pilot bore hole. As the piston then returns, the second stroke, the compressed spring in the head further pulls the long cylindrical casing into the previously made pilot bore hole.

Should an ‘obstacle’ be encountered and forward propulsion hindered, the chisel/crowned head in the reciprocating head will continue ‘chiselling’ independently until the obstruction is fragmented and displaced.

This makes the GRUNDOMAT achieve on- target results even in stony grounds.

Applications & Advantages

UNDER CROSSINGS
Road crossings and property service connections are everyday tasks for the GRUNDOMAT (check correct)

PIPE RAMMING FROM MODEL 130
GRUNDOMATNcan also be used for ramming in steel pipes by attaching a special ram cone to the head of the machine.

PIPE BURSTING FROM MODEL 95
Modified soil displacement hammers are also applicable for pipe renewal using the pipe bursting method.

PILING
Grundomats are also ideal for vertical use, e.g. piling for laying foundations.

PROPERTY SERVICE CONNECTIONS – DIRECTLY FROM INSIDE THE BUILDING
When house connections for gas, water, sewage, electricity, broadband cabling (FTTB) and fibre can start directly from the property. A start trench outside the property wall is no longer necessary. This makes the use even more efficient, and the front garden is spared.

GRUNDOMAT P Series 

Stepped Head 

The proven stepped head is universally applicable in all displaceable soils. The chisel bores forward and ‘opens’ the ground. Step by step the head then penetrates into the ground and works its way forward with great precision. The penetration process is carried out in steps which guarantee a high running stability.

The “head work” is carried out in 3 working steps:

  • Pre-stroke
  • Pulverizing
  • Penetration

Easy switch-over: simply turn the compressed air hose ¼ turn to the left

  • under compressed air: from forward gear to reverse gear
  • pressure less: from reverse gear into forward gear

Pipe Cracking Equipment

Pipe Cracking Equipment

 

GRUNDOBURST rigs are perfectly equipped for pipe renewal using the static pipe bursting method. With the powerful and robust pulling rigs, damaged old pipes with diameters up to 1,200 mm (circular and oval profiles) can be renewed without the need for trenches. Pipe bursting is an acknowledged and most important, sustainable method for renewing pressure and gravity gradient lines; it has been in use all over the world for the past 30 years. Old pipes (VCP, lead, PVC, PE, grey cast iron, ductile iron, AC,GFRP, steel etc.) are replaced by new pipes (PE, PP, VCP, ductile cast iron, GFRP, steel, PVC etc.) with identical, smaller or larger diameter pipes.

 

 

The Advantages

  • Can be used for almost any types of damage and any kind of old pipe materials
  • Long service life for the new pipe, 80 – 100 years
  • The old pipe capacity can be scaled up by 1 – 2 nominal sizes
  • QuickLock: simple and safe rod connections – engage with a click, no screwing together;
  • even small bend radii can be accessed
  • Fast installation and set-up times
  • Renewal of already existing pipe-line routes
  • 40 % cost saving in comparison with open trench methods
  • Minimal disruption to the environment and traffic flow
  • Almost no re-instatement costs due to ground settlement, groundwater interference
  • No road damage after pipe bursting
  • Safe application according to latest rules and standards

HDD Equipment

Horizontal Directional Drilling Equipment

 

‘HDD technology’ is widely-used in the civil engineering. Its share compared to open trenching is ever increasing because the underground installation and renewal of supply and (disposal) pipes bears major technical and economical advantages.

These advantages are due to excavation and re-instatement work being almost omitted and the short construction times and show especially when producing property service connections and when crossing much frequented roads.

Trenchless installation protects the environment. That means: no surface disruption, no problems with inhabitants, minimal excavation, less construction machines plus avoidance of traffic jams, diversions and repair work, as well as low emission of noise, (CO2) and fine dust particles.

The Advantages

  • The slim design allows drilling with minimal clearance to buildings
  • High corrosion protection, e.g. due to fully galvanised rod boxes
  • The engine hood is made of weather-proof GRP
  • The electronics are shock- and vibration-proof
  • High quality manufacturing and certified supplier components (motors, pumps etc.)
  • Highly resilient, fail-safe and service reduced
  • High value stability
  • Wide range of applications

Ramming Equipment

The GRUNDORAM – Dynamic Ramming Technique 

GRUNDORAM pneumatically driven pipe ramming machines are used for the dynamic installation of steel pipes underneath roads, waterways, railway tracks, parks, etc. over lengths of up to 80 m. The TT ramming technology provides thrust forces up to 40.000 Nm, enabling the economic installation of open end steel pipes up to 4000 mm diameter in soil classes 1 – 5 (in part even class 6 – easily soluble rock) without the need for jacking abutments.

The steel pipe ramming technique is suitable for installing longitudinally or spirally welded pipes, seamless pipes and pipes with insulation protection as product pipes, e.g. in pipeline construction, or as casing pipes for supply und drainage pipe bundles. The pipe rammers are also used horizontally for constructing underpasses, small outlets, pipe roofs for tunnel structures, for supporting HDD bores (HDD Assist) with vertical applications being used for foundations, sheet piling or well drilling.

Advantages of the technique:

  • Less disruption and damage to surfaces worth conserving (road surface, water courses, railway embankments etc.) and minimal restoration – giving economic advantages
  • Low social impact because, diversions, half-sided barriers, traffic signal facilities etc. are avoided
  • Acknowlegded pipe installation technique
  • Short setting-up times – short installation times
  • The dynamic impact when ramming can shatter obstacles and easily overcome difficult starting resistance after standstill periods. The aiming accuracy is improved because the dynamic impact penetrates various soil formations within the diameter range and obstacles do not have to be displaced or pushed aside in one piece
  • No jacking abutment, no auger cutter required, which could get jammed
  • The soil core remains in the pipe during ramming, i.e. no rush of water when rivers or areas with a high water table are undercrossed
  • Minimal ground covering, i. e. no large-scale pits
  • Simple operating technique
  • Adaptation to all pipe diameters with special ram cones
  • Wide range of applications

GRUNDORAM Technology

The air driven piston inside the machine body strikes against the ramming head. The kinetical impact energy which is released that way enables maximum advancing of the pipe string due the optimal force transmission via the cones. As the constant loads affecting the machine require maximum product quality, the one-piece casing (head and casing are made up of one part) is made out of a solid block which is thoroughly galvanised. The piston is subject to an elaborate hardening process, a tight sealing minimises air consumption. The GRUNDORAM stands for durability and reliability.
