18、mber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governme

19、ntal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Dire

20、ctives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bod

21、ies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts i

22、n an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is appr

23、oved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed a

24、gain after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or

25、 all such patent rights. ISO/TS 10465-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 6, Reinforced plastics pipes and fittings for all applications. This first edition of ISO/TS 10465-1 cancels and replaces ISO/TR 10

26、465-1:1993, of which it constitutes a technical revision. ISO 10465 consists of the following parts, under the general title Underground installation of flexible glass-reinforced pipes based on unsaturated polyester resin (GRP-UP): Part 1: Installation procedures Technical Specification Part 2: Comp

28、ngs was approved at that subcommittees meeting in Oslo in 1979. An ad-hoc group was established and the responsibility for drafting various standards later given to the Task Group that would become ISO/TC 138/SC 6. At the ISO/TC 138/SC 6 meeting in London in 1980, Sweden proposed that a Working Grou

29、p be formed to develop documents regarding a code of practice for GRP pipes. This was approved by the subcommittee and Working Group 4 (WG 4) formed for the purpose. Since 1982, many WG 4 meetings have been held and have considered the following matters: procedures for the underground installation o

30、f pipes; pipe/soil interaction with pipes having different stiffness values; minimum design parameters; an overview of various static calculation methods. During this work it became evident that unanimous agreement could not be reached within the Working Group on the specific methods to be employed.

31、 It was therefore agreed that the related documents would be published as either Technical Specifications the case for this part of ISO 10465 or Technical Reports. This part of ISO 10465 describes procedures for the underground installation of GRP pipes. It concerns particular stiffness classes for

32、which performance requirements have been specified in at least one product standard; but it can also be used as a guide for the installation of pipes of other stiffness classes. ISO/TR 10465-2 presents a comparison of the two primary methods used internationally for static calculations on undergroun

33、d GRP pipe installations: a) the ATV method 1; b) the AWWA method 2. ISO/TR 10465-3 gives additional information which is useful for static calculations primarily when using an ATV-A 127 type design system in accordance with ISO/TR 10465-2 of items such as parameters for deflection calculations, soi

34、l parameters, strain coefficients and shape factors for flexural-strain calculations, soil moduli and pipe stiffness for buckling calculations with regard to elastic behaviour, parameters for re-rounding and combined-loading calculations, the influence of traffic loads, the influence of sheeting, sa

Since publication of the previous edition of this pa

37、rt of ISO 10465, both the AWWA and the ATV-DVWK design systems have been revised and now contain design features which reflect the increased knowledge and experience gained by the pipeline industry during the last decade. The revision of this and the other parts of ISO 10465 has been made to take ac

38、count of those changes. NOTE Although significant advances in trenchless construction have been made in recent years, this type of installation has not been considered.

39、P) Part 1: Installation procedures 1 Scope This part of ISO 10465 describes the procedures for underground installation of flexible glass-reinforced thermosetting resin (GRP) pipes. It refers generally to GRP pipes as specified in the system standards ISO 10467 and ISO 10639, but it can also be used

40、 as a guide for the installation of other GRP pipes. It does not include jacking, relining or above-ground installations; nor does it cover health and safety or environmental conditions, these being addressed in national regulations at the place of installation. NOTE The installation nomenclature, d

41、imensions and soil moduli zones referred to in this part of ISO 10465 are shown in Figure 1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edit

42、ion of the referenced document (including any amendments) applies.

44、prevent flow of water along the trench through the bedding and foundation materials NOTE Trench-stops can be formed from clay which may be available on-site, or from bags of sand, or cement stabilized sand, packed around the pipe and across the trench extending to within 150 mm of the finished surfa

45、ce. 3.2 bulkhead concrete wall poured around the pipe and spanning the trench NOTE The bulkhead is keyed into the trench walls to form a pipe anchor and extends to within 150 mm of the finished surface level. Drainage holes are normally placed at the lower part of the embedment zone to eliminate lon

46、g-term retention of water behind the bulkhead. See Figure 1.

49、ipe. The performance of GRP pipes is primarily controlled by the external and internal loads applied and the resistance provided by the embedment conditions. Allowable strain levels within the pipe wall vary, depending upon a) the type of raw materials used to manufacture the pipe, b) pipes wall formation, and c) manufacturing process. Several installation design procedures exist which can be used to determine the deflection that can be expected in a particular installat
