Wall for impact of Dozers
Wall for impact of Dozers
(OP)
Anybody knows this block manufacturer?
These are 2ft x 2ft x 6ft.
Trying to find an economical solution to keep them from rolling out.
Dozers pushed the material against the back wall- Anybody ran to this situation in past?
Any solutions?

Thank you

RE: Wall for impact of Dozers
I can't imagine a cheap way of keeping a bulldozer from doing something that it's not supposed to do. Sober them up maybe? Tell the drivers to park their trucks on the other side of the wall?
The steel kickers aren't a terrible idea, but that will add up.
When I am working on a problem, I never think about beauty but when I have finished, if the solution is not beautiful, I know it is wrong.

Blocks like that are common, but typically of a design unique to local concrete companies. Excess concrete in a batch gets dumped into the molds, and the blocks are sold to contractors and state DOT's. Alternatively, they are made to order by the concrete company for large projects.
A better design for a loader bunker is either a) no end wall (let the loader approach from either end to scoop up a load) or b) pour a sloped/tapered end wall for the loader bucket to scrape up against. Expect wear damage for the latter, but I've seen these last quite awhile.

I suppose this is a slightly passive aggressive suggestion, but here goes... Measure the distance from the front of the blade or bucket to the back of the operators seat and add 10-15', this is the harpoon handle length. Locate the harpoons horizontally every 3-4' apart all long the back wall and sticking into the bldg. Place them vertically at about the top height of the back of the operators seat. The material should flow freely btwn. the harpoons, sharpen harpoons, and let er rip.

3DDave,
Thanks for my new design philosophy. A few of iterations of doubling the prior failure ought to get me there, as you say. 'Shame for the folks on the first couple of rounds, of course...

I am sorry I am not following the harpoon method.
What is a harpoon? You put them horizontally and vertically ?
Could you possibly attach is sketch? It sounds an option but I dont whats a harpoon? and not clear of the locations u mentined
Thank you.
oldestguy (Geotechnical,
Thank you for you reply.
A question, if I lay the first layer short face perpendicular to wall and then next layer parallel to wall then the third layer will be perpendicular to wall and cantilevering? Can 4 feet of block cantilever?
A stetch meay help. Thank you

This is figuring only one wall gets the pressure, Wall B

One mounts "pikes" (medieval long sticks with a spear-point on the receiving end horizontally on the wall. Each point shall be the length from the wall to midpoint of the longest bulldozer seat from the bulldozer blade, sufficiently high to allow clearance for the bulldozer blade and engine.
Intent is to prevent impact of the bulldozer blade to the wall by allowing the bulldozer operator a clearly visible "warning point" as the bulldozer approached the wall so that the bulldozer operator stops the bulldozer before hitting the wall.

If the pile has been freshly stocked the front end loader will not reach pike-engagement range before the material itself is pushed against the rear wall causing further damage. I propose a spring-actuated pike tied to a pressure sensitive plate on the rear wall.
This will also have the added benefit of a 'warning' system letting the operators know of their impending impalement as the pike inches its way towards them.
