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 30 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 two 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

GRUNDOMATN: VERSATILE APPLICATION

  • UNDERCROSSINGS
    Road crossings and property service connections are everyday tasks for the GRUNDOMATN hammer.
  • 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 MODEL95
    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) 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.

for FTTB, gas, water and power property service connections

  • Minimal set-up times mean the soil displacement hammer can be started from inside the building after the core bore through the wall
  • A wall duct is set up on the inside and seals off the basement wall from the outside and inside.
  • The Grundomat and equipment fits into a small transporter van
