BS EN 1610:2015EN 1610:2015 (E) 6 1 Scope This European Standard is applicable to the construction and related testing of drains and sewers usually buried in the ground and usually operating under gravity but up to 0,5 kPa when surcharged. The construction of pipelines operatin

28、g under pressure is covered by this European Standard together with EN 805 as appropriate (e.g. for testing). This European Standard is applicable to drains and sewers installed in trenches, under embankments or above ground. For trenchless construction EN 12889 applies. Additionally, other local or

29、 national regulations may apply, e.g. concerning health and safety, pavement reinstatement and requirements for tightness testing.

Some of these terms are illustrated in Figure 1. 3.1 bedding part of the construction which supports the pipe between the trench bottom

42、Illustration of definitions 4 General 4.1 Technical principles Pipelines and manholes are engineering structures in which the combined performance of construction components, embedment, initial and main backfill and native soil constitute the basis for stability and safety in operation. The pipes, f

43、ittings and joint materials supplied, together with the work carried out at site, such as the pipe bedding, the jointing of pipes, the sidefilling and backfilling are all important factors in achieving a structure with adequate performance over the intended service life.

44、(E) 9 The network owner and the planner shall coordinate the extent and the requirements of the engineering services to be rendered for the individual case. The pipeline shall be designed during planning in accordance with EN 1295-1 and EN 752 as applicable to ensure it is capable of carrying all fo

45、reseeable imposed and operational loads (including construction loads, that may be determinant for dimensioning) with a sufficient level of safety. A procedure shall be established for the resolution of technical questions, agreement and recording of changes to design decisions made during construct

46、ion. 4.2 Safeguarding design decisions In the execution of the work it shall be ensured that the decisions made in the design are complied with or adapted to changed conditions. The design decisions may be affected by variation of any of the following which should be checked during installation: tre

47、nch width (see 6.3); trench depth; trench support system and the effect of its removal (see 11.5); degree of compaction of the embedment; degree of compaction of main backfill; pipe support and trench bottom conditions; construction traffic and assumptions concerning temporary loads; soil types (e.g

48、. subsoil, trench walls, initial and main backfill); shape of trench (e.g. stepped trench, trench with sloping walls); ground and soil condition (e.g. affected by frost and thaw, rain, snow, flooding); ground water table; additional pipelines in the same trench; existing infrastructure (e.g. pipes,

49、cables, structures); pipe type, strength or class. NOTE The above list is not exhaustive. 4.3 Short sections of trench Particular attention should be paid to: foundation conditions, construction steps and transition; shear load bearing capacity of the joints and bedding, e.g. meeting the hardening times in the case of concrete bedding; responding to soil changes in the trench bottom; BS EN 1610:2015EN 1610:2015 (E) 10 securing of the initial and main backfill from the previous section; continuous measurement and adjustment of
