Name of the construction: D1 highway Jánovce- Jablonov, 2nd section, Tunnel Šibenik
Location: Levoča, Construction object: SO 401-00 Tunnel Šibeník
Investor: Národná diaľničná spoločnosť, a.s. Mlynské nivy 45, 821 09 Bratislava
Contractor: “Association EUROVIA – SMS – D1 Jánovce – Jablonov, 2nd section“
Tunnel Šibeník main constructor: TUBAU, a.s. Pribylinská 12, 831 04 Bratislava
The work of tunnel contractor (TUBAU, a.s.) consisted of realisation of SO 401 objects group (Tunnel Šibeník). The tunnel Šibeník is one of the first constructions of this kind in Slovakia realised in “yellow FIDIC” contractual system.
TUBAU Company realised complex construction of the tunnel. The tunnel is realised as rural zone twin tube highway tunnel with one way traffic and 100 km per hour speed limit of the category 2T-8,0. The length of each tunnel tube is 588 metres, out of which 540 metres is the length of tunnelled section in each individual tube. The tunnel tubes are mutually connected with one passable cross interconnection. The whole project consists of 15 construction objects and 18 technological objects.
Tunnelling works were realised by NRTM method using blasting. Secondary lining consisted of 91 blocks in both tunnel tubes out of which 47 blocks were reinforced and 44 blocks were not reinforced.
The integral part of Tunnel Šibeník construction was the delivery and installation of technological equipment of the tunnel itself.
Tunnel objects technology consists of:
• Technological centre – ventilation technology, heating, wiring and fixed fire extinguishing equipment installation.
• Grounding system of the tunnel objects and the other parts.
• Fire extinguishing water main technological equipment.
• Low and high voltage connections.
• Transformer centre for tunnel, tunnel power connection.
• Building with fire extinguishing water reservoir – installation of ventilation, heating, wiring and technological equipment.
• Tunnel lighting.
• Video watching and video detection system in the tunnel.
• Tunnel central control system, traffic control system, and communication system.
• Tunnel ventilation, inner physical parameters measurement.
• SOS chambers
• Electronic fire warning signalisation, electronic security signalisation.
