Abstract

U ovom radu analizira se hidraulički proračun zatvorenih kanala u kojima se kroz tlačnu cijev gravitacijski prenosi voda ispod cesta, željeznica i drugih građevina – sifona. Sifoni su jedna od vrsta malih hidrotehničkih građevina za odvodnju površinskih i oborinskih voda kod prometnica, a iako naizgled jednostavne građe, sifoni moraju zadovoljiti određene zahtjeve kako bi njihova struktura bila adekvatna za njihovo pravilno funkcioniranje. Zbog navedenog promatrana je hidraulika sifona i cjevovoda općenito kako bi se moglo dobro razumjeti funkcioniranje njihovog rada i postizanje veće ekonomičnosti, čemu pridonosi i strukturni integritet same cijevi koji je također razložen. Naposlijetku, promatrani su i pokusi kojima se proučavala nova teorija o radu sifona koja polazi od premise da voda koja protječe sifonom nije homogena tekućina.

Abstract (english)

This paper analyzes the hydraulic calculation of siphnos - closed channels in which water is gravitationally transmitted under roads, railways and other structures through the pressure tube. Siphons are one of the types of small hydrotechnical structures for drainage of surface and stormwater in roads. Although seemingly simple built, siphons must meet certain requirements in order for their structure to be adequate for their proper functioning. Due to the above, the hydraulics of siphons and pipelines in general were observed in order to be able to understand better their and to work on a more sufficient level. Structural integrity of the pipe itself also contributes to siphons work more sufficient, which is also explained in this paper. Finally, experiments were observed to study a new theory on the operation of siphons, which starts from the premise that the water flowing through the siphon is not a homogeneous liquid.
