Gradnja in preskušanje cevovodov za odvod odpadne vode in kanalizacijo

Ta evropski standard obravnava polaganje in preskušanje vodov in kanalov za odvajanje vode, ki so navadno položeni v zemljo in običajno delujejo v pogojih težnosti (s prosto gladino). Ta evropski standard obravnava tudi gradnjo tlačnih cevovodov, pri čemer je treba po potrebi upoštevati tudi standard EN 805. Ta standard se uporablja tudi za izvedbe vodov in kanalov v jarkih in pod nasipi ali za namestitev nad terenom. Za izvedbo brez izkopa se uporablja standard EN 12889. Dodatno naj bi se upoštevali drugi lokalni predpisi, npr. v zvezi z zdravjem in varnostjo, vzpostavitvijo prvotnega stanja na površini ceste in zahtevami za preskušanje tesnosti. Ta standard se ne uporablja za načrtovanje in oblikovanje v skladu s standardom EN 752.

Overview

EN 1610:2015 - Construction and testing of drains and sewers is a CEN European Standard that sets out recommended practices and test procedures for the construction, installation and acceptance testing of buried drains and sewers that normally operate under gravity (and when surcharged up to 0.5 kPa). The standard covers pipelines installed in trenches, under embankments or above ground and includes requirements for bedding, embedment, backfilling, manholes and final leak-tightness testing.

Key topics and technical requirements

EN 1610:2015 addresses practical and technical elements of sewer construction, including:

• Scope and definitions - applicability to gravity sewers and interfaces with pressure-pipeline requirements.
• Trench construction and stability - trench widths, trench bottom preparation, stability and safe working space.
• Bedding and embedment - recommended bedding construction types (Type 1, 2, 3) and special support methods.
• Materials and backfill - use of native and imported materials for embedment and main backfill; compaction principles.
• Installation practices - handling, storage, pipe laying, jointing, setting out, socket holes and provisions for future connections.
• Manholes and inspection chambers - construction, connections and testing requirements.
• Testing during and after construction - conditioning and acceptance testing, including air testing (method “L”) and water testing (method “W”) for leaktightness of gravity pipelines, plus joint testing.
• Dewatering and temporary works - recommended dewatering methods (Annex A) and trench support/removal procedures.
• Inspection, qualifications and documentation - visual inspection criteria, testing procedures, and personnel qualifications.

Practical applications and who uses this standard

EN 1610 is aimed at professionals involved in wastewater infrastructure delivery and asset management:

• Civil engineers and design consultants specifying sewer works
• Construction contractors and site supervisors performing trenching, bedding and backfilling
• Utilities and asset owners setting acceptance criteria for new sewers and drains
• Inspection and commissioning teams conducting air/water tightness tests
• Authorities and procurement teams referencing standards in contracts and technical specifications

Use cases include new sewer installation, extensions, replacement of pipelines, manhole construction and acceptance testing for new or rehabilitated drainage systems.

Related standards

• EN 12889 - trenchless construction methods (applies when trenchless techniques are used)
• EN 805 - requirements for water pipelines under pressure (used together with EN 1610 where pressure testing or pressure pipelines are relevant)
• National regulations and guidance (listed in Annex D) may supplement EN 1610 for health & safety, pavement reinstatement and local testing procedures.

Part 1: General requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. The same definitions apply for trenches with vertical or sloping sides and for pipes laid below embankments. Some of these terms are illustrated in Figure 1. 3.1 bedding part of the construction which supports the pipe between the trench bottom and the sidefill or initial backfill Note 1 to entry: The bedding consists of upper and lower bedding. In the case of the pipe laid on natural trench bottom, the trench bottom is the lower bedding. 3.2 compaction layer thickness thickness of each new layer of fill material prior to its compaction 3.3 depth of cover vertical distance from the top of the pipe barrel to the surface 3.4 embedment fill around the pipe including bedding, sidefill and initial backfill SIST EN 1610:2015

Figure 1 — 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, fittings 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. SIST EN 1610:2015

A procedure shall be established for the resolution of technical questions, agreement and recording of changes to design decisions made during construction. 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: — trench 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. 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, 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; SIST EN 1610:2015

¶ 200; — 40 mm for DN > 200 up to DN
¶ 600; — 60 mm for DN > 600. — For DN < 100 all written instructions of the manufacturer shall be complied with. 5.2.2 Native soil Re-use of native soil shall meet all the following requirements: — it is permitted by the works specification/design; — it complies with any compactability requirements in the works specification/design; — it is free from materials detrimental to the pipe (e.g. "oversized" particles, tree roots, waste, organic material, snow and ice) and any clay lumps larger than 75 mm. Native soil meeting the requirements of 5.2.3.2 or 5.2.3.4 is considered suitable. 5.2.3 Imported materials 5.2.3.1 General The following materials which may include recycled materials are suitable. Environmental consequences should be considered. SIST EN 1610:2015

National regulations should be checked for compliance. 6.3 Trench width 6.3.1 Maximum trench width The trench width shall not exceed the maximum width specified in the structural design. If this is not possible, the matter shall be referred to the designer. 6.3.2 Minimum trench width The minimum trench width shall ensure a minimum working space overall as the greater of the values taken from Tables 1 and 2, except as provided in 6.3.3.

The working space, on the side of the pipes and manholes to be built, shall be available for all works without any restriction. For pipes
· DN 600 laid in supported trench or unsupported trench where mechanical compaction of bedding and sidefill is required, working space x/2 should be at least 0,5 m. In this case the minimum trench width should be ODh + 1,00. It can be necessary to define a trench width narrower than the minimum defined in 6.3.2 e.g. in the following circumstances: — where personnel access to enter the trench is forbidden; — where personnel will never be required to enter the trench or the space between a pipeline and trench wall, e.g. automated laying techniques; — in unavoidable constricted situations; e.g. because of difficult localized conditions on site; — when using self-compacting filling materials. In each of these cases special measures including safety precautions are required in design and construction to ensure the protection of workers in the trench and national regulations should be checked. In the event of deviations from the trench widths defined in the structural design of the pipes, the structural design shall be checked or revised (see 4.2). 6.4 Trench stability Stability shall be ensured either by means of a trench support system, by battering the trench sides to a stable slope which can be maintained during the works or by other suitable means. The maximum depth of unsupported trenches with vertical trench walls shall be limited according to national regulations and in any case less than 1,4 m. 6.5 Trench bottom The gradient of the trench bottom and the trench bottom material shall comply with the design specifications. For the trench bottom, at least the original load bearing capacity of the native soil is required. Trench bottom material should not be disturbed. If it is disturbed, its original bearing capacity shall be restored, e.g. by excavating to undisturbed ground and replacing with appropriate compacted material. SIST EN 1610:2015

Pipes may be laid directly on the trimmed bottom of the trench. The thickness b of upper bedding shall be as specified in the structural design. SIST EN 1610:2015

Figure 5 — Bedding construction type 3 7.3 Special methods of bedding or support Where the trench bottom has low bearing strength, special construction measures are necessary. This is likely to occur in unstable soils, e.g. peat, running sand. Geotextiles can be used to stabilise the bedding. Examples of possible measures include replacement of soil with other materials, e.g. sand, gravel and bonded materials, or supporting the pipeline on piled structures, e.g. using cross beams or cradle support, longitudinal beams or reinforced concrete slabs spanning the piles. Consideration should also be given, during design and installation, to the transition from one ground condition to another with different settlement properties. Special methods of bedding or pipeline support shall only be used if their suitability has been confirmed by structural design calculations. NOT
