My cottage road was like that every spring,in about 3 or 4 places....doesn't seem to happen anymore! But for 4 or 5 weeks a year we have to walk in about 4 km carrying our supplies! Was great fun lol!
Have worked on these. The thing that happens with them is, the culvert gets jammed full of gravel, stone and debris. They get jammed to the point where no water is able to flow through them naturally, and so, they will get pushed out of place by the weight of the water that has built up in the ditch. All the surrounding material soaks up water and gets push along with it. We used a Vac Truck to blow out the debris that has been stuck in the culverts. This had to be done before each big rain.
Depending on the amount and type of traffic involved, could you perhaps locate some old railroad ties and dig them "into" the road? How often does this type of event occur?
And downstream - that’s where the scouring occurred and washed under, removing the bedding. A head wall at up and downstream and some very large rip rap are needed.
Maybe put a wide pipe in that space where are the road is washed out and a new culvert is forming, then fill the space around it with gravel, sand and clay dirt. So maybe water can flow through and under the road! 😅 Maybe a pipe can prevent more erosion. I would consider using a good, fast growing local plant (weeds lol) that can grow in that type of soil and has deep roots to plant all around on the side the water flows from. Maybe shrubby or tree type "weeds", you know, to help prevent erosion. 🤷🏼♀️🤷🏼♀️
Typically happens if something plugs the culvert up and water starts bypassing around the culvert, end result is a washed out culvert. A much larger culvert will help, but you will need to monitor the upstream sides of all culverts and keep them clear of debris
Kinda what I figured, pretty amazing what mother nature can do. Will be working on a more long lasting solution in the near future. Thank you for your input, all is needed.
@@bumblingfool You can do DIY geogrid If you imbed old tires in the gravel surface above and off to each side of the culvert. Just lash them together with stainless steel wire before filling with stone. You'd probably want to leave a lower spot in the road so overflowing water has a channel across but I've seen videos where such a thing will survive one heck of a lot of water overtopping it. It's good for muddy areas for the same reasons.
@@bumblingfool you can cover the low crossing with cememt, to prevent it getting carved again into a ravine. If it gets filled with debris, it will be easier to clean than a culvert.
@@bumblingfool You could, Cut down some trees. Square off a Good size like 10x10 and then the length you need and set that down. on the ends dig down a bit throw some bags of concrete to hold the placement of those boards. If you have any scrap metal and some rocks around you can put in that concrete to help it. That should work for a long time. if you want you can throw some rock down on top that will smooth the edges and give some weight to it.
The county kept trying to put a culvert in, close to where I go hunting. You can see all the different sizes washed out into the woods. They eventually put a train car in. It was cylindrical with each end cut off and the wheels removed. After the second one blew out into the woods, they quit trying.
Would be nice to know Where; Australia, Canada, N. Zealand, USA ? . . . And What territory or state ? . . . "Hiway138" doesn't narrow it down very much . . . ☆
@@bumblingfool LOL! It looked deep. Like, deep enough that my F-250 (stock, 4x4) would get stuck. Then I though Bigfoot and bulldozers. Hope you get it taken care of quickly!
@@GuretoSefirosu We got it filled enough for single vehicles to make it through. One of the guys is watching a dozer on an auction site. Hope he gets it!
@@vJackaRoo It is common during the rainy part of the year, but the only maintenance is by the people who live here. Very little equipment, or money. However, we are working on it!
