as a geotech engineer, i like the way you're using to reinforce the slope with wood! excellent work with available material. please take action to prevent rotting of woody materials. also this slope is vulnerable to scouring.

Incredibly lush and fertile soils there! What a cool method for building up a road. I’ve never seen that type of retaining wall system made like that before.

its called Krainerwand method and was created in the rugged mountains of Slovenia by some clever slovenian civil engineers when it still was a part of the austro hungarian empire when the wood rotts away the material long has settled and has become stabile , the wood thereby is sacrificial , the liftime of the road exceeds the woods existence

You guys are doing a great job, thanks for showing all this great process
I am also adding a comment by Stanislav Bystriansky, a Slovak expert who dealt with the construction of forest roads. Machine translation: AMAZING! This should be seen by all those who build forest roads on steep slopes with dredger technology and care that the impact on the landscape is minimal. The cut-out section has a minimum width because the embankment slope of the road can also have a similar slope as the cut-out, i.e. 1:1. In our country, due to the landslide, it is usually 1:1.25. What is the width of the crown of the road (in our country it is 4.5 m) and how is the drainage handled? Well, the gravelly soil is ideal for the road exhibition. Interesting: the path to the upper reservoir of PVE No. starts at Svarín. Libra. Right behind the bridge over the river No. The scale was an intolerable wetland (trail) and so the wood was laid first - tree trunks on which coarse stones were poured, then macadam and finally gravel layers.

what happens when the wood rots, does the road slid away.
nice, i would have done with railroad ties probobly, but i dont have to much experiance building roads

Ну разве в таком бережном хозяйстве возможен пожар? Молодцы просто. Вы пример для всего мира. А зеленые активисты должны задуматься над своим поведением.
Cute little road and cute little equipment. Could we see that again using a Cat D9 and maybe a little wider.

Pridávam aj komentár Stanislava Bystrianskeho, slovenského experta, ktorý sa zaoberal výstavbou lesných ciest: ÚŽASTNÉ ! Toto by mali vidieť všetci, čo budujú lesné cesty v strmých sklonoch bágrovou technológiou a záleží im na tom, aby zásah do krajiny bol minimálny. Vyrúbaný priesek má minimálnu šírku z dôvodu, že aj násypový svah cesty môže byť v podobnom sklone ako zárezový a teda 1:1. U nás z dôvodu zosuvu býva miernejší 1:1,25. Aká je šírka koruny cesty (u nás býva 4,5 m) a ako býva riešené odvodnenie ? Nuž a tá štrkovitá pôda je pre výstavu cesty ideálna. Zaujímavosť: na Svaríne začína cesta na hornú nádrž PVE Č. Váh. Hneď za mostom cez rieku Č. Váh bola neúnosná mokraď (trasovisko) a tak sa najprv položila výdreva- kmene stromov na ktoré sa nasýpali hrubé kamene, potom makadam a napokon štrkové vrstvy.
@@emr6391 Thank you very much for answer. In Slovakia we admire of Japan precision in work. And building of forestry roads are on Slovakia passionately discussed theme for ecological reason. And I looked your other videos - it is absolutely beautiful and amazing work!! And active managed forests (with cutting trees) have better ecology parameters and storage more carbon oxide than non managed forests, speak scientists in Slovakia. Very passionately discussed theme in Slovakia is how to manage forest with most ecology and nature-near methods - on this theme work o lot of scientists in Slovakia. But Slovakia is poor country, we have no money for more ecology methods in forestry management (foresters are not financially supported how farmers from state). Building and maintenance of forestry roads is very important in forestry and it is you beautiful work :).
Using trees you had to cut anyways as a geotextile substitute was a clever move, Ihave to wonder how long the logs and the road bed would last and would that be long enough?
@HakunaMatata00910 ай бұрын
The purpose of the log is as retaining reinforcement while the nature heal to its natural form. As the time goes by, the logs surely will rotten away but by the time that happen, everything around there already settled with its permanent soil, tree roots and everything.

wont that wood retaining structure rot eventually, putting a life span on the stability of the road? i understand your using what's in your hands reach...
