2. FOUNDATION PILES
Foundation piles either convey the superstructure load to a deep and resistant subsoil layer through soft and unfit grounds, or they spread the weight of the construction to wide layers of the soil adequately resistant to the load. They are associated to particular foundation issues, to dangerous subsoil...

3. JET GROUTING
Jet-grouting is performed through different techniques, mainly through injections of fluids varying from 1 up to 3. It is applied to loose soils, cohesive formation and decomposed rocks.The diameters of the resulting beams vary according to the numbers of the fluids used: from 40 to 80 cm. diameter if...

4. MICRO-PILES
Though included in the drilling piles category, micro-piles are particularly used to consolidate the foundations of existing structures. Their diameter varies from 6 to 35 cm. and they can be performed either vertically or sloping by perforating the foundation to be consolidated and by taking away the soils...

6. SHEET-PILING
Sheet-pilings are a particular group of piles formed by isolated elements fixed onto the ground, yet connected one another in order to form an uninterrupted bulkhead, sideward pressure resistant. Sheet-pilings can be built in wood, iron, (Larssen type) or in reinforced concrete, either built out of the...

7. LOAD TEST ON PILE
The load test analyses the altering behaviour of pile-soil compound for loads up to 1,5 times higher the operating load.The test is carried out by setting a hydraulic jack between the top of the pile and the existing foundation beam. A 3 cm. thick steel plate is set between the pile and the beam and an ...

8. INTERVENTION OF A SLOPE STABILIZATION
In a stabilization project, the geotechnical interventions adopted to increase the safety far beyond the limits provided by laws, are chosen according to the peculiarities of the physical -evolutional model of the real or hypothetical instability and in relation to the elements distinguishing and causing...

9. SICC PILE
Drilling execution is performed through a particular hollow rode equipped with a coiled spire whose ratio between wing height and the rod diameter varies between 20% and 35% . They combine thrust and rotation actions set on the operating machine. During the drilling performance, a compression of the soil ...
