Inflatable packers “Geopack “ are used for cement injections in geotechnical applications to consolidate and/or to make imperme-able foundations and tunnels and during other consolidation works. They are also used to perform Lugeon tests.
There are two methods for using them: A single packer
which allows to pressurize the cement mortar injected below. A
double packer which is normally used inside tubes fit-ted with valves, in the way which allows to inject mortar from each valve independently.
They were constructed deliberately to solve the problems during the cement injections.
A hand-pump (or 230V elec-tric pump) starts a hydraulic piston which compresses two special elastomer elements attached to steel rings with the same diameter. While stretched, rubber optimizes the leak-tightness inside the micropiles and tubes fitted with valves.
After simple shifting of some elements, they can be used as a single packer or a double one, depending on needs.
The rubber rings of our hydraulic packers are interchange-able, so it is possible to use them with tubes and micropiles of different diameters, which reduces expenses.
