2 Types of application The sheet pile steel or composite representing the sector of pride for Dewatering & Silent Piling Capable of intervening in the work of both provisional type that permanent, disposing of professional skills, qualifications of techniques, tools and resources necessary for the proper and timely management of all the issues at stake. 1) CIVIL ENGINEERING: retaining walls; earthworks; foundations; buttresses of road and rail bridges; ramps; road and rail tunnels; underground roads; underground parking; construction of homes and structures. 2) ENVIRONMENTL PROTECTION: conterminazioni of polluted soils and contaminated soil areas; earthworks for replacement of the soil; walls of protection for tanks; noise barriers; pumping stations; power plants. 3) MRITIME ENGINEERING: docks; Docks docking ships Ro-Ro facilities; reinforcement of embankments; protection from erosion; dams and protective walls at high tide; foundations of bridge piers; navigation canals.

4 Respect for the environment Dewatering & Silent Piling is very attentive to thisaspect and preliminary studies often begin with their own tests to measure the amount of noise and vibration in the surrounding yard, so opt for those implementing rules that minimize these impacts. When working near or within sensitive buildings, noise and vibration propagation in soil issues are deeply felt, and in this Chimin Sp has always invested to upgrade its technology, vibratory hammers replacing those standards with high frequency and variable frequency and buying a hydraulic press silent piler piling static. Zero vibration and very quiet. The hydraulic press silent piler is perfect for interventions in residential areas and in the vicinity of buildings Static piling at zero vibrations The static embedding in an environmentally responsible zero vibrations and silence is perfect for interventions in residential areas and near buildings or sensitive items For these reasons are increasing the demands for action hydraulic press with Silent Piler, Dewatering & Silent Piling and the only reality in Europe to have updated in this direction. how does hydraulic press silent piler? The HYDRULIC PRESS SILENT piler moves on the sheet pile and sinks without vibrations each new section in the ground on the same exerting a thrust force obtained from the resistance to extraction of those previously fixtures. ddattissima for cohesive soils but also for granular, and where the soil is very compact, you can take action pre-operating holes or by coupling the drive to press with high-pressure water jet is able to break the layers more difficult. Productivity and flexibility of use are much improved if you use the jet: a spear with a plate is welded to the mounting pile and both are inserted into the ground simultaneously; once it reaches the desired depth, the spear is removed and then reused

6 Equipments available Vibratory Hammers high-frequency and variable frequency according to the law relating to frequency, vibration and noise associated hydraulic power related. Vibratory Hammers available : ICE RFSH 8 ; PVE 2312 VM ; PVE 2320 VM ; PVE 2324 VML PVE 2335 VM. Lifting equipment : Liebherr crane lattice mod. HS 845 HD crawler 70 ton ; Bendini cranes telescopic mod. Terex to 60 tons ; hydraulic crawler excavator CT 336 UPPER HHD ; hydraulic crawler excavator CT 330 UPPER HHD. Truck mounted platforms. Where if the need arises, can also be realized with anchors or bolts underground systems contrast with struts, chassis stiffening internal or head to the rafters with piles of breakdown. With the ultimate goal of ensuring a complete service to the customer, Chimin works closely with a structural engineering firm to a high standard and with companies that offer complementary services to the sheet piling, type wellpoint systems for dewatering the aquifer. Types of intervention permanent works and / or provisional with vibratory Hammers; permanent works and / or provisional without vibration emission and low noise emission with hydraulic press Silent Piler / Still Worker; sheet pile definitive view for underground parking underground car parking ucp; rental and sale sections.

8 Benefits of the definitive sheet pile the benefits of building technique with sheet piling in view than conventional techniques with concrete cutoff walls and Berlin micropiles are: Rapid execution no need to implement guide kerbstones and consequent demolition of the same; intervention without the use of mortars to dry bentonite or polymer resulting in problems and charges of disposal of special waste in landfills; speed of execution of the work (an average of 15/20 linear meters per day); no need to wait ripening times, then proceed immediately with the excavations by speeding and reducing costs; excavation performed to proceed immediately with the floor slabs, columns and floors being the steel wall ready for work. This construction technique has been applied for from now Chimin Sp only for underground parking, but others are scenarios in which it can be exploited, such as pumping stations or storage tanks. Cost savings elimination of charges related to the security and support of excavation slope (the estimated costs for temporary works are transformed into the final cost of the works); elimination of cost and time for the realization of the wall including, charges more for larger excavations, formwork, reinforcement, waterproofing, etc. Guarantee high quality guaranteed waterproof to water infiltration or groundwater. On the whole surface of the traditional diaphragm the material presents a certain level of porosity, however with a good piling gargame well welded or treated with special gel ensures permeability nothing. structure is guaranteed to seismic actions that the fire without the use of intumescent paints in compliance with the current regulations. When the work provisionally scheduled for the temporary support of excavation slope becomes in effect a definitive work

9 Construction phases for the construction of underground steel sheet piles Clean the area and Install sheet piling definitive structural Training internal pillars underground with technical bored piles Jet partial attic floor and installing wellpoint dewatering system for groundwater Excavation to share training attic basement intermediate through the openings left on the ground floor slab Jet partial attic basement intermediate Excavation to share training lower basement slab casting slab basement lower Completion of the deployment slabs from the the lowest to the ground floor and disassembly wellpoint

10 Special Foundations Types of intervention Laying steel piles and concrete of any diameter and length for vibroinfissione Running pilings piles for vibroinfissione (without land drilling and extraction) bored piles included supply and service jet Cls; supply and installation of metal armor; use of bentonite mud / polymeric hole walls for stabilization; Use pipe shape for covering the hole; Dispose of in approved landfills drilled. Laying steel poles of any diameter and length for vibro piling

15 Dewatering systems with the use of dewatering wells are used in the presence of excavation in predominantly gravelly and stony soil litotypes, inside which there is a high water supply from the aquifer. These soils have very high average transmissivity so the extraction well must have the characteristic of containing pumps of large flows and diameter. s part of the technology of drainage wells, we can outline two different methods, that influence the choice of pumping. The two different ways of dealing with the problem of dewatering wells, permit, the first to perform dewatering by gravity, the second to perform forced depression of the acquifer.
