The static pile pressing method provides silent pile driving, prevents a destructive effect on adjacent buildings and structures, allows high piling speed and accuracy along with continuous monitoring of pressing force. For penetration of piles, we use specialised hydraulic pile driving machinesthat generate a pressing force of up to 320 tonnes. The machine's design allows to drive effectively RC piles of any length and cross section at a rate of up to 500 running metres per shift.
Revvork’s laboratory has all the appropriate equipment andfor static soil testing. The laboratory staff carry out testing by pressing, pulling and horizontal loads at the survey phase prior to building design, during the piling process and when accepting piles in position. A report is provided to customers after each testing. All tests are conducted in accordance with the State Standard (GOST) 5686-2012 “Soils. Field pile testing methods”.
As an official partner of Gersevanov NIIOSP (Agreement on collaboration in developing and improving technologies and designs of foundations and footings), Revvork LLC offers advanced optimisation methods for design solutions aimed at reducing financial and time expenditures in the construction of foundations. All solutions undergo expert reviews at NIIOSP and are supported by cost-effectiveness analyses.
Revvork’s fleet allows pile penetration using the static pressing (with pilot drilling, if necessary) of sheet piles of any length (pipe sheet piles – up to 530 mm in section, Larssen sheet piles – L4, L5). Under complicated construction conditions, this sheet piling method is the most effective and preferable one. The pipe sheet piling penetration rate of one Starke YZY-320 ranges from 300 to 500 running metres per shift.
In some cases, it is advisable to use foundation soil strengthening technologies as an alternative to foundations of reinforced concrete piles. Revvork’s experts can offer the following solutions:
(a) static soil compression with stamps of a pile pressing machine;
(b) soft soil compaction with macadam, sand and ground piles.
These solutions have been successfully implemented by our specialists and have proven their effectiveness and efficiency.
Under complicated geotechnical conditions and where impact or excessive loads on soil have to be reduced, a need may arise to drill pilot wells prior to penetration of piles and sheet piles. For pilot drilling, our company employselectrically-driven rotary drilling rigs that can drill wells up to 26 m deep, using an integral auger, and up to 800 mm in diameter.
