Micropali
The micropiles allow to solve some problems related to the construction of foundations, thanks to the possibility of using equipment of reduced size and size, and the least disturbance to the ground and to existing structures.
Large diameter bored piles
We produce bored piles with diameters of 400 mm to 1500 mm in any soil condition, even in the presence of rock and soil, with or without the use of the bore coating, or by using bentonite or biodegradable sludge.
Concrete diaphragms
The diaphragms are walls built in the subsoil starting from the surface. Their use has evolved from the use of the first years of the last century to use bentonific sludge for the drilling of wells in order to stabilize uncoated holes. They are made by digging a trench, using bentonite mud, then installing an armature and placing the mud with the next concrete casting.
The wall is used as excavation support, foundation element or as a containment structure for groundwater flow. Diaphragms play an important part in underground construction work, also because they can be built with a relatively low degree of disturbance.
Jet Grouting
The Jet Grouting treatment technique allows the improvement of the mechanical characteristics and permeability of the soil by treatment with acua / cement mixture injected at very high speed. The Jet Gruoting treatment lends itself to being used in difficult logistic conditions, confined spaces, obstacle crossing, high depth treatment with vacuum crossing. The construction of consolidated elements§ (generally columns) takes place starting from small diameter perforations (normally between 100 and 140 mm), with the help of light and handy machines. Generally the treatments are performed up to a depth of 20-30 meters, even if particular projects have been carried out with depths up to 100 meters. All Jet Grouting techniques provide a first drilling phase followed by a phase of ascent and rotation at predetermined values with simultaneous high pressure injection of the fluids used:
Water recharge
Trivellamento terrains of any consistency and nature.
We create water wells for use: domestic industrial sports centers, green areas and geothermal municipal areas.
Drilling technique:
drilling system with direct circulation of bentonite sludge with core destruction: we use debris containment systems surfacing on the surface to avoid dispersion and obtain the maximum possible cleaning of the surrounding hole area.
Air drilling system with hammer bottom hole.
piling
metal bulkheads are a very common technology in various engineering environments. They represent an advantageous solution in the excavation support, in the bank protections, in the works in the riverbed, to cite only the many possible applications.
Metal sheet piles are very versatile works; easy to lay, they represent very used structures, above all in provisory conditions.
The most visible application of the sheet piling is that of excavation support works. The shape of the sheet piling makes it suitable also for contexts in which the stratum is superficial and to be laid in water.
Tie rods and anchors
The tie rods are structural elements subjected to traction, suitable for transmitting loads in depth.
The tie rods are composed of an active part, a true anchorage, and a passive part, ie transfer of the stresses of the anchorage head on the structure to the ground, the tie rods can be injected at low pressure, or at high pressure, while in reference to durability over time they are differentiated into tracts and final stays.
Piles thrown into place
The thrown poles are performed in situ without removal of soil, required by the insertion of a tube closed at the bottom by a lost or recoverable caseback.
The infixion is effected by a diesel or hydraulic hammer.
Once the infixing has been completed, the reinforcement cage and the concrete are put into operation and the shaped tube is extracted using a vibrating clamp. This technique and the specially designed equipment allow to reach maximum depths of 25-27 meters with diameters ranging from 335 to 610 mm.
