ACO Tiefbau devised the watertight expansion joint element (see also the upper image on page 20)  to ensure that the connections of the drainage channels with each other and with the neighbouring components remain flexible and nonetheless impervious to liquid Quelle/credit: ACO Tiefbau Vertrieb GmbH

A flange-like connection forms the basis of the expansion joint, in the case of which a stainless steel element (V4A) is connected with the end surfaces of the channel bodies. The structure remains impervious to liquid even given considerable movements in a lateral direction and/or in a vertical direction Quelle/credit: ACO Tiefbau Vertrieb GmbH

Nowadays tunnels represent elements of an economic and ecological infrastructure. To ensure that tunnels are kept in the best possible state and to cope with ever increasing volumes of traffic, refurbishment measures as recently carried out at the Rendsburg Canal Tunnel are essential. Three construction phases involved measures for repairing the concrete on the floor and the walls, fire protection, road construction, and drainage.The refurbishment also includes rescue and evacuation facilities and technical installations.

As early as the tunnel planning stage, the infrastructure and installations have to be taken into consideration, which act in a preventive manner, i.e. that avoid critical incidents as far as possible. In the event of rehabilitation it is particularly essential to introduce the high safety standards of the European Tunnel Guideline 2004/54/EU and ZTV-ING, Part 5 Tunnelling (Additional Technical Contractual Conditions) that apply for Germany in their latest form as well as RABT regulations 2006 (Guidelines for the Furnishing and Operation of Road Tunnels).
