Using self-compacting flowable backfill materials can be beneficial if the related workflows are aligned with the specific requirements associated with their use.


Atv-dvwo-a course you can browse through our shop without having to register first. Compared with the previous Standard the chapters “Inspection Chambers” and “Underrun with Elevator” have been added.

Temporarily flowable self-compacting backfill materials can be manufactured from native soils, manufactured soils or suitable recycling materials.

Hydrology and Water Resources Management.

These concern, inter alia, the following subjects:. The present paper emphasizes the atv-dvwm-a of sewer trench and embedment construction, as well as temporarily flowable, self-compacting backfill materials. Drainage and sewer systems are key to ensuring hygienic, environmentally sound conditions in all municipalities and local communities.

This Standard applies for structures in sewer systems outside buildings, which are newly installed or rehabilitated.


Since only little hands-on experience has been Sewer System Structures, November For reasons of environmental protection, as well as from the operational, technical safety and economic aspects, there are principles and minimum requirements on the design and quality of the construction of sewer systems.

Designers should be aware of the common processes and work steps involved to prevent the issues described above, which particularly applies to the design of the pipeline embedment and bedding.

Construction and testing of drains and sewers

Requirements on the soil-mechanical properties and especially on the long-term properties need to be defined and monitored, taking into account the interactions with the surrounding soil and groundwater.

Surface Water and Soil. In the process, errors may be committed such as: In addition, numerous proposals on the optimisation of planning have been incorporated. Errors can be safely prevented by providing regular training and performing checks during installation of the bedding and backfill alongside the pipeline.

However, placing an order and downloading materials is only possible for registered users. The paper presents the experience gained and statements made with regard to profitability. The aim of this paper is to discuss briefly the most significant changes in DWA-Awhich correspond A further objective was the matching of the Standard to the current developments of European standardisation.

Objective of the revision of the previous Standard dated March is the increased orientation of the planning towards the economic construction and operation of sewer systems. Intelligent concrete products such as the PerfectPipe type of pipe Fig.

The use of these construction materials dispenses with the need for mechanical compaction processes.

Drain and Sewer Systems. In the process, errors may be committed such as:. These concern, inter alia, the atv-dvqk-a subjects: Hydraulic Engineering and Hydro Power.

Introduction Quite a number of papers were presented at past editions of this congress to report on progress in the drafting of the above worksheets. If you have not created an account yet, you can do so here.

Expectations have been met by the experience gained with using this pipe system. An essential property of flowable fill should be the long-term suitability for removal using lightweight equipment. When you use this website, you accept the use of cookies.
