So it’s a glorified cylinder jumping on its piston, pretty nifty

[@gomerromer7708]

These pilings are not just hollow centrifugally cast, they are also pre-stressed with post-tensioned tendons. I am not sure why they go for so long with single impacts. We lived with the BNSF railroad rebuilding a bridge near our house in St. Paul MN, They were putting in H pilings about 16" across the flanges. These were 60 feet long and they would weld a second on when they got the first one in. They would start the hammer running by itself right from the start. The last 10 feet, usually with about 75-85 feet of pole down, would shake the entire neighborhood. They would e getting no more than an inch per strike and would still keep going. The foreman would chalk inchmarks on the piling once they got to a certain point.

It appears that in the beginning they were taking steps to ensure the pile was properly aligned before driving it very far (the same idea as lightly tapping a nail into lumber while keeping it aligned with your fingers, until it's okay to let go and just swing the hammer). In a lot of cases the operation of the pile driver does not become self-sustaining in the beginning because weak soils at shallow depth provide too little recoil to propel the weight high enough for it to trigger ignition on the subsequent drop, but I'm not sure if that was an issue here or not. FWIW, that marking of the piling toward the end of the process that you observed allows them to determine if there's enough resistance to penetration that there's no need to drive it farther. This degree of resistance is predetermined by the engineer. Commonly, they work with one-foot increments, but whatever the unit of measure, they keep driving the pile until the number of blows needed to drive it "one increment" is greater than the assigned value.

[@gomerromer7708]

@@ericl2969 Thanks, good information. The phrase you see in specifications often is "driven to refusal." I first watched any form of pile driving up close when I was in the U.S. Army in Brazil in 1969-1970. I made friends with four Brazilian civil engineers. One worked for a contractor doing low-cost public housing, 4-story walk-ups without elevators. Rio de Janeiro is a bunch of basalt mountains with filled in swamps in between them. Once you are away from the rock, it is hard to get foundations. For low-rise buildings they had cast-in-place concrete mushroom pilings.They would suspend a thick-wall concrete pipe from one cable on a crane. The second lifted a heavy cylindrical weight that fit inside the pipe with an inch or so clearance all around. The pipe would be rested on the ground, the weight inside, which looked like an ovesized welding gas cylinder lifted up perhaps 5-6 meters and dropped. It would punch down into soft ground and the surrounding pipe would follow. They would keep going until they pipe was perhaps eight meters in the ground. Then they would lift the weight or hammer up far enough so that then could hoist a side-discharge comcrete bucket up on the crane's third cable and dump perhaps a sixth of a cubic meter of medium slump concrete. They would drop the hammer once, raise it out of the casing, rais the casing up about 60 cm. dump in another shot of concrete, drop the hammer, lift out, raise the casing, add more concrete until they got to grade level. The crane would move away and a crew of guys would work a pre-made cage of rebar down perhaps three meters. This was not heavy, four 5/8ths vertical with a stirrup or band of 3/8ths around it every 30 cm. or so. I think the number of these that they put in varied with the soil conditions. They would put them in roughly under where each vertical column in the building would be but they did not seem to care much about precision. Before they started to go up they would tie all the columns together with what were essentially a grid of horizontal beams built with forms at grade level to spread the weight of the building across all the pilings. Supposedly dropping the weight once on each batch of concrete would form a series of mushrooms sort of like a Dari-Queen cone. Building codes were not all that rigorous. For more sophisticated buildings like the 20-story condos that populte residential neighborhoods like Ipanema they had more sophisticated piling systems and often had caissons. They would have to do extensive de-watering. But they seldom if ever used steel H-pilings. At that time there was only one office tower in Rio that was built with structural steel, the Edificio Central.

Fascinating piece of gear. I've seen these from a distance but this is the first time I've seen one up close. Thanks for filming this.

Just like a piston engine, except the piston is fixed and the cylinder moves up and down. Interesting.

OK, good analysis bro 👍

When they were putting the 515 extension to the middle of Las Vegas, they used one of these. I think it was in the early 80s amazing thing to watch.

[@lawrenceveinotte]

I worked in a shop that had a diesel fired power hammer, worked much like a pile driver, wish I knew where it is now.

[@janupakubumi]

OK, bro... that means we both operate diesel engines... Best wishes always from Indonesia🇲🇨

[@gomerromer7708]

I have heard about these, never seen one. I do hand blacksmithing and wish I had a power hammer. The Meyers Brothers Little Giant ones had a toggle system. You can get the Kuhn air-operated ones from Germany for thousands of dollars, but you also need to have a construction size air compressor. I understand that the diesel ones were to get away from the need for air compressor capacity. But they were pretty dirty and it was impossible to vent them directly to the outside. You had to have an exhaust hood above them and a fan. Does that match what you saw?

[@cranemanandyegan9347]

Drove pilings with a Linkbelt diesel hammer this hammer is backwards, the cylinder goes up and down, the linkbelt the piston goes up and down interesting.

[@IO-zz2xy]

Yes you are correct. It is a much more compact design. I suspect that weights could be added on top for more heavier hammer action?? Regards from South Africa

[@ronblack7870]

cylinder is heavier than the piston usually

[@ironmartysharpe8293]

I've seen pyledrivers in action building bridges in my area , How far down do they drive those pyles

[@cranemanandyegan9347]

@@ironmartysharpe8293 It depends on engineering of stucture and soil condition. most are 75 to 150 in length they are driven to "refusal" that is a predetermined blow count per foot. Example refusal is 200 blows per foot the pile is driven when you hit it 200 times and it does not move 1 foot. There is a inspector that watches and has a machine that sits on the ground and it counts the blows. the pile is marked before fifting with 1 foot increments.

Only after the last piling was installed did they realize they were all upside down.

No bother, they just hammer up rather than down to extract it.

[@millwrightdad3753]

Being concrete these pilings didn’t survive all the way down

[@trappenweisseguy27]

I wonder if the soil directly underneath the piling behaves a bit like quicksand from the force and vibration ?.

[@colintuffs568]

Vibro drivers are different machines relying on the weight to sink . This operative with the piece of string finally got the diesel to work smoothly ❤😊

[@ericl2969]

That can happen, depending on soil conditions, though "vibration" in that case is not quite what most people would imagine since it occurs only for an instant with each blow. But the principle is the same. This does not happen once the pile reaches its design depth where penetration resistance is far greater.

How do they inject the diesel?

Diesel Injected thru the center of the bottom piston, when the hammer at bottom stroke it triggers a linkage attached to a pump to inject diesel

[@billdoodson4232]

@@balachdr5 Thanks. I assume that these give a "soft" push on the pile, rather than a hard strike.

[@gomerromer7708]

@@billdoodson4232 No, they are no different than the compressed air or steam hammers that preceeded them. Yes, their maximum hit may be less than an old-fashioned drop hammer but those are slow to operate.
