CONSTRUCTION OF THE CANAL THROUGH FATNIČKO FIELD COMPLETED

The works on construction of canal through Fatničko polje was successfully completed on Novemebr 08, 2018.

An open channel through Fatničko polje is a hydrotechnical structure in the hydroelectric system Gornji Horizonti in the Trebisnjica River Basin. The canal connects already built tunnel Dabars field – Fatničko field and tunnel Fatničko field – accumulation of Bileća. It is intended for the convey water without losses between future HPP Dabar and HPP Bileća. The water that is being processed in the HPP Bileća will be introduced into the accumulation of “Bileća“ and it will continue to be used in the existing HPP Trebinje I, HPP Trebinje II, HPP Dubrovnik and PHE Čapljina – they have been successively operating since 1965 (HPP Dubrovnik) until 1981 (HPP Trebinje II). In this way, the production of electricity in these hydroelectric power plants will be significantly increased.

Brief summary and work description:

Construction of the canal through Fatničko field is executed in two sections.

Section 1 (l =2,086 m):

Cross-section of the canal is a trapezoidal canal with bottom width of 10 m and slope inclination of 1:1.5. Reinforced concrete MB30 lining of thickness of 20 cm is performed in sections of length of 5 m. Section is dimensioned on the flow Qmax=121,50 m3/s, which is the maximum capacity of the tunnel Fatnica – Bileća.

Section 2 (l = 491 m):

Cross-section of the canal is a trapezoidal canal with bottom width of 10 m and slope inclination of 1:1.5. Reinforced concrete MB30 lining of thickness of 20 cm is performed in sections of length of 5 m. Section is dimensioned on the flow Qmax=93,00 m3/s.

On the chainage 2+752,23 km, canal is over concrete sill of spillway connected with the exit of tunnel Dabar – Fatnica. The spillway length is 26 m, with initial transitional section of length of 8 m. Its width on the bottom is 5 m, and inclinations of lateral sides are 1.7:1.

The bridge span of 27.40 m is constructed over the canal in this section.
