GRUNDOBURST 2500 G

THE RENOVATOR

GRUNDOBURST 2500G
THE BEST THING FOR PIPE RENEWAL

QUICKLOCK BURST RODS
  • Quick locking couplings without thread (QuickLock), no lubrication required, therefore no time consuming screwing together required
  • Quick rod insertion and removal
  • The rods are connected faster than threaded rods
  • Absolutely push and pull resistant
  • Able to negotiate bends
  • Integral production, therefore highly resistant to stress
  • Robust, low-wear as clamping is not required
  • No slipping back of the rods, due to direct force transmission
  • Rod system with convenient rod accessories
  • Longer service life than screwed rods
  • QuickLock bursting rods are available from 35 mm diameter for pipes from ND 50
  • Other rod diameters: 54 mm, 75 mm, 100 mm, 120 mm and 140 mm

PULLING FORCE MEASUREMENT GRUNDOLOG

  • Monitoring and logging of pulling force imparted on new pipe during installation
  • Performance categories: 150kN, 400kN, 1,250kN, 2,500kN
  • Self-sufficient storage and live transfer of data possible
  • Compact dimensions for small pits
  • Can be applied from a pit in both directions
  • Fast operating cycles and high output
  • Rapid rod pushing through old pipe and during new pipe installation
  • Quick to get started
  • All machine models have remote control
  • Low weight for easy transport
  • Accessories specific to the procedure
  • Stable and job-site specific constructionto withstand the highest of loads and strain
  • Long service life and lowmaintenance effort
  • Ergonomic operation andhigh level of work safety
  • CE-certified
TECHNICAL SPECIFICATIONS
  • The GRUNDOBURST 2500G sets the benchmark for trenchless pipe renewal. It generates a maximum pulling force of 573,262.70 lbf (255 t). This allows the renewal of old pipes from ND 11.81 to ND 47.24 inches
  • The rods are 86.61inches long and weigh 462.97 lbf each. For steel pipe relining projects, mains lengths up to 4,199.46 ft can be pulled in.

RENEWAL OF A COMBINED SEWER PIPE WITH GRUNDOBURST 2500G

The town of Wiehl, located in the Oberbergisch District is not exactly large in terms of area and population, but nevertheless has quite a few interesting sights to offer. For instance, a public stalactite cave with an 868 m long tunnel system, a 13,4 km length panorama trail (the so-called “Beer Trail”), the “Axle, Wheel and Carriage” Museum, which presents the 5.500 year history of the automobile industry and a wildlife park with a 1,8 km long nature trail.

This combined sewer was built about 50 years ago with reinforced concrete pipes with the nominal widths 600 and 700 mm, but now a camera inspection reported a series of cracks, fractures and tree ingrowth. A conventional sanitation was out of the question, as on the one hand, the cross-section had to be upsized and on the other hand, the static load of the damaged reinforced concrete pipes was no longer guaranteed, due to the excess cover, oppressive slope and the country road just above the slope.
