INFLATABLE PACKER
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.
Inflatable packers
Examples of application
- Consolidation of ground in different depths
- Consolidation of unconsolidated material
- Consolidation of fissured solid rock
- Injections in building components
- Injections into the soil below building components
- Sealing works
- Lifting injection
Advantages
- Reusable
- Material-conducting parts of stainless steel or with hardened sealing surface
- Easy and safe sealing of boreholes
- Can be used in different depths
- All parts are easily exchangeable
Installation
Depending on the type of packer a securing cord or the material hose is used to place the packer in the borehole. The inflatable packer is lowered in the borehole either by the securing cord or the material hose. After the injection the packer can be safely removed and reused. If the borehole is not vertical the inflatable packer must be placed with linkage.Expansion range of the 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.
Approvals
Inflatable packer with deaeration
Description
The venting of air guarantees that the entire cavity can be filled since no air is left to prevent the injection material from flowing. The inflatable packer with deaeration is especially useful in problematic structures where it is necessary to eliminate and prevent the formation of cavities which could allow water to penetrate.Application
The inflatable packer with deaeration is inserted into the borehole and expanded with minimum pressure to avoid damaging the structure. The filler material (acrylate gel) is injected with a suitable injection pump - the inflatable packer with deaeration allows air to be released so that the entire cavity can be filled.Cleaning
The cleaning set, developed especially for use with the inflatable packer, allows all relevant parts (including material tubes and purging conduits) to be thoroughly cleaned and re-used.Note
The single inflatable packer with air purge is available separately. All additional parts such as filling tube and venting tube are replaceable!double inflatable packers Flex
Application range
The double inflatable packers are mainly used for injections with sleeve pipes. These injections serve for improvement of mechanical properties, for sealing purposes or for the consolidation of ground, rock, building components etc.Examples of application
- Consolidation of unconsolidated material
- Consolidation of fissured solid rock
- Injections in building components
- Injektionen in Bauteile
- Injections into the soil below building components
- Sealing works
- Lifting injection
Advantages of double inflatable packers
- Reusable
- Safe sealing
- Large inflation range: 1 double inflatable packer - different diameters
- Variable contact pressure
- Hardened sealing surface
- All parts are easily exchangeable
- In different lengths available
Sealing
The inflation hose of the double inflatable packers adapts itself to the shape of the boreholes or the sleeve pipe granting a good sealing which can be controlled by the inflation pressure. After the double inflatable packers have been inflated it is granted that the injection material can only come out laterally. This allows the accurate placing of the injection material.Expansion range inflation hose
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. Moreover 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.2C inflatable packers
Fields of application
The 2C inflatable packers are used when quick-reacting two-component injection material is applied and the two components have to be delivered separately to the mixing tube.
Examples of application
- 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
