Abstract
Zima in zimsko vzdrževanje gozdne ceste destruktivno vplivata na cevne propuste in zmanjšujeta njihovo funkcionalnost ter povečujeta vzdrževalne stroške. Namen dela je na izbrani Novi Javorniški cesti v revirju Otok - Karlovica ugotoviti število in stanje cevnih propustov ter vpliv zime na njihovo delovanje. Za ugotavljanje stanja cevnih propustov smo izdelali snemalne liste in popisali vse cevne propuste na Novi Javorniški cesti v dolžini 10 km. Stanje smo ugotavljali jeseni pred prvim snegom, spomladi po odjugi, nato pa še čez eno leto. Če primerjamo prvi in zadnji popis, vidimo, da je razlika pred prvim snegom in po odjugi precej velika. Pred prvim snegom je bilo največ zamašenih vtočnih jaškov od 11 % do 50 % (50 %), najmanj zamašenih vtočnih jaškov je bilo od 81 % do 100 % (10 %). Pri zadnjem popisu, po odjugi, pa je bilo največje število zamašenih vtočnih jaškov od 81 % do 100% (40 %), najmanj pa je bilo vtočnih jaškov, katerih zamašenost je bila do 10 % (10 %). Podoben rezultat je bil tudi pri zamašenosti cevi cevnih propustov. Pri prvem popisu, pred prvim snegom, je bilo 30 % cevi z zamašenostjo do 10 %, ravno toliko cevi je bilo zamašenih od 81 % do 100 %. Pri zadnjem popisu pa je bilo 50 % cevi, ki so bile zamašene od 81 % do 100 %.Najmanj je bilo zamašenih cevi do 10 % (10 %). Ugotovili smo, da zima in padavine povečujejo zamašenost cevnih propustov, zato je potrebno redno čiščenje in vzdrževanje le-teh tako, da je odvodnjavanje vode urejeno že pred jesenskimi padavinami.

Abstract:
Winter conditions and winter maintenance of the forest road have destructive impact on pipe culverts, as they reduce their functionality and increase maintenance costs. The purpose of this work is to establish the number and status of pipe culverts and the influence of winter on their function at New Javornik Forest Road, district Otok - Karlovica. To this end, we have drawn uprecord lists and made an inventory of all pipe culverts in a length of 10 kmof the New Javornik forest road. The status was established before first snowfall in autumn, after thaw in spring and one year later. A comparison of first and last records shows a noticeable difference in the status before first snow and after thaw. Before first snow, the clogging of majority of inflow shafts ranged between 11 % and 50 % (50 %), the smallest number of inflow shafts clogged in a range from 81 % to 100 % (10 %). However, last record taken after thaw shows the largest number of inflow shafts clogged from 81 % to 100 % (40 %) and the smallest number of inflow shafts clogged up to 10 % (10 %). Comparable results were established as regards the clogging oftubes in pipe culverts. The first record taken before first snow indicates both 30 % of tubes clogged up to 10 % and tubes clogged from 81 % to 100 %. The last record, however, indicates 50 % of tubes clogged from 81 % to 100 %. The smallest number of tubes indicates clogging up to 10 % (10 %). We have established that winter and precipitations increase the likelihood of clogging of pipe culverts, thus necessitating regular cleaning and maintenance there of in such a manner that drainage of water is taken care of before autumn rainfalls.
