22、699:2015) has been prepared by Technical Committee CEN/TC 288 “Execution of special geotechnical works”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by

23、October 2015, and conflicting national standards shall be withdrawn at the latest by October 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such pa

24、tent rights. This document supersedes EN 12699:2000. The technical changes in comparison to EN 12699:2000 are: driven piles independent of dimension are included; sections describing concrete and testing have been minimised. The document has been prepared to stand alongside EN 1997 (all parts), Euro

25、code 7: Geotechnical design. Clause 7 covers design aspects of piles. Annex A and Annex B are informative. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cro

26、atia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

27、the United Kingdom. DIN EN 12699:2015-07 EN 12699:2015 (E) 5 1 Scope 1.1 This European Standard establishes general principles for the execution of displacement piles, that means piles which are installed in the ground without excavation or removal of material from the ground except for limiting hea

28、ve and/or limiting vibration as well as removal of obstructions or to assist penetration. Piles are driven into the ground using impact, vibration, pressing, screwing or a combination of these methods. 1.2 The material of displacement piles covered by this European Standard can be: steel; cast iron;

29、 concrete, mortar; timber; grout; combination of above. 1.3 This European Standard covers prefabricated, cast in situ, or a combination of these methods to form displacement piles of regular shape. Examples are given in Figure A.2 and Figure A.3. 1.4 Displacement piles may be installed in soils enha

30、nced by ground improvement techniques. The ground improvement can be executed before, at the same time or after installation of the piles. 1.5 Other than practical considerations there are for the purpose of this European Standard no limitations regarding cross section dimensions, shaft or base enla

31、rgements, length or rake. 1.6 The provisions of this European Standard apply to: single piles; pile groups; concrete sheet piles. 1.7 Columns constructed by ground improvement techniques (such as mixed in situ columns, jet grouting, compaction grouting, vibro flotation, stone columns) are not covere

32、d by this European Standard. Bored piles are covered in EN 1536. Steel and timber sheet pile walls are covered in EN 12063. Micropiles are covered in EN 14199. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for i
