Injection system

INFLATABLE PACKERS

Inflatable packers are used for injections in nearly all areas of the boring technology, tunneling, and special civil engineering. These injections generally serve for the improvement of mechanical properties or for sealing purposes. Moreover in the field of borehole measurement technique inflatable packers are used for test injections, water pressure tests, and for geological reconnaissance boreholes.

Sealing and expansion range inflation hose

The advantage of inflatable packers is the large expansion range of the inflation hose. According to the type of packer the expansion ranges to the double of the minimum borehole diameter. Moreover the inflatable packer generates a perfect sealing effect as the inflation hose optimally adapts itself to the shape of the borehole. Over the whole length of the inflation hose an even contact pressure is granted.


DOUBLE INFLATABLE PACKER

Double inflatable packer

Applications

  • Consolidation of ground in different depths
  • Consolidation of unconsolidated material
  • Consolidation of fissured solid rock
  • Injections in building components
  • Injections in foundations
  • Injections into the soil below building components
  • Sealing works
  • Lifting injection

Advantages

  • Reusable
  • Safe sealing
  • Large inflation range
  • Variable contact pressure
  • Material-conducting parts of stainless steel
  • All parts are easily exchangeable
  • In different lengths available

Sealing and expansion range inflation hose

The double inflatable packer generates a perfect sealing effect as the inflation hose optimally adapts itself to the shape of the borehole or the sleeve pipe. Over the whole length of the inflation hose an even contact pressure is granted. The advantage of the double inflatable packers is the large expansion range of the inflation hose. The expansion amounts up to the double of the minimum borehole diameter so that only 1 packer is needed for sleeve pipes of varying sizes.


2K INFLATABLE PACKERS

2K inflatable packers

Applications

  • Consolidation of ground in different depths
  • Consolidation of unconsolidated material
  • Consolidation of fissured solid rock
  • Injections in building components
  • Injections in foundations
  • Injections into the soil below building components
  • Sealing works
  • Lifting injection

Advantages

  • The 2 components of the injection material are separately delivered to the mixing tube where it is mixed by a variable number of static mixing elements
  • Several times reusable as both material tubes as well as the check valves can be rinsed separately at the packer
  • Large expansion range of the inflation hose granting a perfect sealing effect in the borehole as well as a variable contact pressure
  • Can be used in different depths

Sealing and expansion range inflation hose

A securing cord fixed to the packer serves for placing the 2K inflatable packer. After the injection work has been finished the securing cord can be used to remove the packer from the borehole. The advantage of the 2K inflatable packer is that the two components of the injection material are separately delivered to the mixing tube. Here a variable number of static mixing elements produce the mixing result which is best for the respective injection material. The two material tubes and check valves can be rinsed separately at the packer. A further advantage is the large expansion range of the inflation hose. According to each type of packer the expansion ranges up to the double of the minimum borehole diameter. Moreover the 2K inflatable packer generates a perfect sealing effect as the inflation hose optimally adapts itself to the shape of the borehole. That is why an even contact pressure is granted over the whole length of the inflation hose.
