The technical and technologic actions for the applyment of the nautical mechanization for water system maintenance of the Savsko Jezero lake in Belgrade

Abstract

Whether a water system is artificially created, or a water system is a natural habitat created by man’s influence (rivers, lakes - both artificial and natural, channels and ponds), a constant maintenance of these systems is required, in order for them to fulfill their function. Maintenance of a water system implies a complex and regular appliance of certain technical and technologic actions which enable a constant and efficient functioning of the water system, according to its functionality. The work shows a complex overview of the problems during technical and technologic actions of the nautical mechanization during the process of vegetation removal from the Savsko Jezero Lake’s water system. The objective of the work is aimed at determining the causes and consequences of the excessive growth of the aquatic plants in the Savsko Jezero Lake, mechanical ways of vegetation removal, as well as technical and technologic actions of the applyment of an Alpha Boats FX-6 nautical mower at the Savsko Jezero Lake. Based on theoretic researches in the field of aquatic plant repression and a practical appliance of the specialized nautical mechanization Alpha Boats FX-6 at the Savsko Jezero Lake in Belgrade, it could be concluded that: - Mechanical ways of repression of the excessive aquatic plant growth has proved to be one of the ecologically best solutions for the problem, - Large quantities of the plant material (up to 35 m3 daily) which is extracted from the lake and driven to a dump site, generates a question for the further use of the mowed plant mass.

Bez obzira da li su u pitanju veštački akvasistemi ili akvasistemi kao prirodna staništa pod antropogenim uticajem (reke, jezera-prirodna i veštačka, kanali i bare), potrebno je redovno održavanje ovih sistema kako bi zadržali svoju funkciju. Održavanje akvasistema podrazumeva kompleksnu i redovnu primenu određenih tehničko-tehnoloških postupaka koji omogućavaju neprekidno i efikasno funkcionisanje akvasistema, prema njegovim namenama. U radu je prikazan kompleksan pregled problematike tehničko-tehnoloških postupaka primene plovne mehanizacije u procesu uklanjanja vegetacije iz akvasistema Savskog jezera u Beogradu. Cilj rada je usmeren na utvrđivanje uzroka i posledica prekomernog rasta akvatičnih biljaka u Savskom jezeru, mehaničkih načina uklanjanja akvatične vegetacije, kao i tehničko-tehnoloških postupaka primene plovne kosačice Alpha Boats FX-6, na Savskom jezeru. Na osnovu teorijskih istraživanja u oblasti suzbijanja akvatičnih biljaka i praktičnoj primeni specijalizovane plovne mehanizacije Alpha Boats FX-6, na Savskom jezeru u Beogradu, može se zaključiti: - Mehanički način suzbijanja prekomernog rasta akvatičnih biljaka pokazao se kao ekološki jedno od najboljih rešenje ovog problema. - Velike količine biljnog materijala (dnevno i do 35 m3) koji se iznosi iz jezera i odvozi na deponiju, otvara i pitanje pronalaska rešenja dalje upotrebe pokošene biljne mase.
