Execution of special geotechnical works - Soil nailing prEN 14490

Scope

1.1 This European Standard establishes general principles for the construction of special geotechnical works involving soil nailing.
1.2 Soil nailing is a construction technique used to enhance / maintain the stability of a soil mass by the installation of reinforcing elements (soil nails). Typical examples of soil nailing are given in Figures 1, 2 and 3.
1.3 The scope of soil nailing applications considered in this European Standard includes the installation and testing of soil nails and the associated operations required when stabilising existing and newly cut slopes and faces.
1.4 Principles for the execution of other similar specialist geotechnical works such as reinforced fill, ground anchors, bored piles, displacement piles, micro piles and tension piles are established in other European Standards.
1.5 The installation and testing of soil nails requires suitably skilled and qualified labour and supervision. This standard cannot replace the specialist knowledge and expertise of experienced personnel.
1.6 Soil nailing may be used to form part of a hybrid construction. This standard is relevant only to the soil nailing aspect of such constructions.
1.7 A construction project may be executed under different contractual arrangements. The responsibilities of all parties involved in the design, execution, testing and monitoring shall be defined in the contract documents (see clause 4).
