Here are some pics of a contract I'm working on, building dikes for a dredge spoils disposal area. Pics are: 1) My machine, a D6R, next to an older D6H 2) The cut, we're taking 3 feet or so to get enough material 3) The push, this is about average distance if we're building it without help from excavators or trucks. 4) Working the outside slope. It's supposed to be 2:1, but this one is probably closer to 1:1. 5) Almost finished with the outside.
6) From the top 7) Another view of the mighty D6
Dike Building A couple of questions.... 1) How many cubic yards were in the dike? 2) What did it cost/yard? 3) How high was the dike at the center? Thanks in advance.
I have to plead ignorance to all of the above. We just build it to spec of height and slope, not by the yard. We're building it up about 6' over the existing dike, which is a bit over 50' above the level of the river if I remember right. In the third pic you can see the existing dike to the right, just beneath the treeline.
Hi dieseldave, that is nice neat work. I pushed up dikes when they were dredging the deep water channel to West Sacramento. Also layed discharg pipe out on the fill with a boom cat. Rain or shine didn't matter as everything was mud and sand anyhow.
Great pictures and some very nice work :notworthy Am I correct in that this is actually a giant dry pond at the moment? How do they deliver the dredge spoils, is it pumped?
Mud and sand, and lots of it:drinkup Were you able to go right out on to the fill with the boom cat, or did you have to use mats? AtlasRob, You're exactly right, it's a giant dry pond. But, it's only dry on the surface- you have to be careful not to go to deep and break through the dry crust, because there's 40' of slimey mud underneath The spoils are pumped in.
Yes you have been there. We had mats made out of oak timbers and a 22B to lay them when needed. That 22B runner had a boring job, the only time he worked was laying mats and digging out the cats when they sank. The most dangerous place was right at the end of each pipe where the muck boiled out and they were hard to see in the dark, especially when the north wind was blowing the sand. The night shift skinner skidding out more pipe was usually the guy that found the holes. The pipe was 32 inches with a belled end and held together with straps welded on. One winter I pulled anchors for the dredge and that was easy duty. A tug would take me to each side of the channel to the winch cats and then back to the dredge to have coffee. The name of the dredge was the San Diego made by Bucyrus Erie.
