Definition of the product and intended use 1.1 Definition of the construction product RR, RRs, RD and RDs steel pile consist of a hollow section structural steel pipe. Pile may also include mechanical joints (external friction splice or threaded splice) or welded joints, a pile tip (rock shoe or bottom plate), a bearing plate or other additional accessories. Steel grades used in RR and RD pile pipes are S355J2H, S355MH, S420MH, S440J2H, S440MH, S460MH, S550J2H and S550MH. Steel grades used in RRs and RDs pile pipes are S550J2H and S550MH. Steel grades S355J2H, S355MH, S420MH and S460MH are standard steels according to EN Steel grades S440J2H, S440MH, S550J2H and S550MH are specified in annex 2 and 3. Diameters of the piles spliced by mechanical splice are from 76.1 mm to mm and wall thicknesses from 6.3 mm to 12.5 mm. Diameters of the pile spliced by welding on site are from 76.1 mm to mm and wall thicknesses from 6.3 mm to 22 mm. Splice welds made on site are not part of this ETA. External splice used in RR and RRs pile is outside of pile pipe locating pile joint where connection is based on friction and conical contact surfaces. Threaded splice used in RD and RDs pile is pile joint with sleeve where connection is based on threads. Bearing plate can be with or without holes, and it consists of steel plate and plate concentrator. Bottom plate and rock shoe are pile tips which are fastened to the lower end of the pile mechanically with friction and conical surface or fastened by welding. Rock shoe is additionally equipped with a dowel made of structural or hardened steel. Pile tip can also has expander head which make shaft grouting possible. The installation procedures of the shaft grouted pile and grouting materials are not part of the ETA. Pile can be supplied with the interlocking sections when the pile is used as a part of retaining wall structure. Dimensions of piles, pile components and accessories are presented in annexes 1, 3 and 5. RR piles and RRs piles are installed by driving (impact driving, jacking, vibrating, screwing) and RD and RDs piles by drilling. Drilling system components are not part of the ETA. Completed piles and design and installation procedures (execution) of the completed piles are not covered by this ETA. 1.2 Intended use RR, RRs, RD and RDs piles are used as the foundation piles in all kind of structures where the pile foundations are needed e.g. buildings, bridges, harbors or traffic structures. The piles are designed generally as an end bearing pile but designing as a shaft bearing pile is also possible. Products can be also used as a part of retaining wall according to EN The piles are designed for loading by axial forces or horizontal forces or combined loads. If the pile is under considerable cyclical stress they must be taken into account separately. The provisions made in this ETA are based on an assumed working life of the piles of 100 years depending of chosen material thickness and environmental conditions which are defined in Eurocode EN paragraph 4.4 and provided that the conditions laid down in this section and sections 4.2/5.1/5.2 for the packaging, transport, storage, installation, and use are met. The indications given on the working life cannot be interpreted as a guarantee given by the producer, but are to be regarded only as a means for choosing the right products in relation to the expected economically reasonable working life of the works. Products belong to Category S/W1: Product in direct contact with soil, ground- and surface water.
