Sažetak
This work presents the project "TUNNEL FOR SAFE TRAFFIC" which is a result of two patent solutions. In this project, the safety elements in the tunnel include multifunctional prefabricated secondary lining, new ventilation system, fire extinguishing by water spray, video-surveillance and fire-alarm. After primary tunnel lining is placed, the elements forming a self-supporting arch are installed by using a special symmetrical scaffold. This scaffold enables the handling and placement of precast elements, which also serve as a self-supporting formwork for filling fresh concrete into the space between the elements and the primary tunnel lining. After having installed the 200 m secondary lining, the installation of ventilation elements can start. These precast elements will play a multiple role in tunnel construction and performance. Their special composite structure makes them fire and water-resistant. Their prefabricated nature keeps construction costs at an acceptable level ; in addition, better quality of concrete is achieved in controllable factory conditions. The specially designed scaffold for this construction system, enables continuous traffic even during the reconstruction of the tunnel, but, of course, with reasonable speed and traffic flow restrictions.
