Trenchless Pipe Renewal using the Push Pulling Method Technology.
Push Pulling Method
Damaged gas and water lines, which must not remain in the ground, can be easily replaced with new pipes in the same bore path using the push-pulling technique.
AT A GLANCE:
The old pipe is completely removed from out of the ground
Destruction of the old pipe in the construction or intermediate pit with the cutting heads
Technique is applicable in all displaceable soils
The pulling force is applied to the old pipe all-over.
Single-stage replacement of old pipes from ND 100 to ND 250 in the same pipe route.
Suitable for old pulling out pipes made of grey cast iron, steel ductile cast iron, asbestos cement and fibre cement.
Pushing in of new pipes made of HD-PE, PP-HM, PE-X and ductile cast iron.
New pipes of equal or larger nominal diameter can be pulled in
Further areas of application
With this Pipe Bursting Technology damaged old pipes with diameters of 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 are replaced with new pipes of identical, smaller or larger diameters with this method which has been used all over the world for the last 30 years.
Standard Pipe Bursting
Pulling in a new pipe of the same size or larger.
Slight reduction of the pipe´s cross-section.
Calibre Pipe Bursting
Damaged pipe sections are expanded statically.
TIP method (Tight in Pipe)
The new pipe fits closely to the internal wall of the old pipe.
The pipe´s cross-section is temporarily reduced in size whilst being pulled in.
Pipe Bursting equipment can also be used for pipe cleaning.
House service connections
Replacement of house service connections with GRUNDOTUGGER.
Why is Pipe Bursting Technology innovative and economical?
50% cost saving in comparison to open trench methods
Renewal of existing pipe-line routes
Almost no re-instatement costs due to ground settlement, groundwater interferences and road damage
Can be used for almost any type of damage and any kind of old pipe materials
The old pipe's capacity can be scaled up by 1-2 nominal sizes
New pipe has long service life of 80-100 years
Short installation and set-up times
Traffic flow and the environment are hardly affected
