With 3 or 4 guys you could probably cut it down to 3hours. My personal best is , but I was in a hurry. You seem to be quite the Shoveler, by the way. The trench I dug was about 6 feet long, 2. Part of the dirt was already turned up, and I think it took me about an hour to get all of the dirt out.
If I had to go another 4 feet deeper, I would not have been able to do it in another hour. It was just a back-of-an-envelope calculation. Once you get down a certain amount where are those extra guys going to stand? The deeper you dig the harder it is, because of the dirt removal. Somebody with a hoist and bucket could make it much faster for the digger.
Then they only lift the soil a couple feet again. My experience at digging garden pools about four feet deep is that earth becomes more densely packed the deeper you go. Obviously a function of the soil type, but at pipe burying depth the soil has been worked by drainage, worms and armadillos. Yes this is very important when considering digging.
For anything in my field of work we typical bring in a backhoe for anything deeper then 4 feet, as it ends up being more cost effective for the customer. It took me about 2 hours to dig all the dirt out. Explore this Article parts. Tips and Warnings. Related Articles. Article Summary. Part 1. Call the municipal government to verify digging the area is safe. Whenever you are digging, you must always first consult your local utilities authority about the underground utilities layout, especially if you live in a suburban or even semi-rural area.
Digging into the layout isn't just disruptive but potentially lethal if you hit electrical wires, gas lines, or water pipes. Even in the mildest cases, a lot of hassle can be bypassed if you contact the proper authorities first. Remember the words: "Call before you dig. If you are in the US, call They will give you a work ticket reference number and let you know when you can expect the inspection to take place.
You'll need to mark the area where you plan to dig with white paint. If you're looking for the right number to call, you can search online: "dig hole" and your city or municipality. The proper authority should come up in the first or second listing. Spray a hole outline. If your hole is going to be any bigger than a post, it is good to first have an outline of how big you'd like the hole to be.
Without a line, diggers have the tendency to miscalculate how big their finished hole should be. With a can of white marking spray paint, spray the area you would like to have dug up. Be generous with the size; it's usually better to have a hole that's slightly too big than one too small for your needs. Gather the right supplies for the job. Due to how many different types and sizes of holes can be dug, there's no all-encompassing list to turn to if you want to know what equipment you'll need.
However, for virtually all kinds of holes, a shovel is necessary. While most of the work may be one with a shovel, other instruments may speed up the process. Though you may want to get the biggest tools available for efficiency's sake, you should choose tools that make sense for your body size. An appropriately-sized tool will keep you from tiring out quickly, thus improving efficiency in the long run. Get your hands on a posthole digger if you need to make holes for a new fence.
You should also consider how you're going to deal with the displaced soil. If you're putting the soil back in the hole once you've dug it up, you can shovel it back. Putting a tarp next to the hole will give you a clean place to place soil. Use a wheelbarrow to dispose of larger amounts of soil. If you plan on setting a post in concrete, have the mix, water, and mixer nearby. You'll also want two stakes of wood and two lengths of wood 1"x4"x5' or so for cross-bracing and screws or Duplex nails for fastening.
Use powered equipment if possible. Only dig by hand if you need to. Digging can be a very physically strenuous activity, and you will be better off if you are able to do it with the help of a machine. For the sake of making postholes for example, you can rent and use a power auger. It is a better idea to rent one than buy one yourself. Depending on the inventory of your local hardware store, you should probably have a choice between a one or two-man power auger.
Base your decisions around the size and amount of holes you need to make. Talk to someone at the hardware store if you're unsure about the details. If you have to dig many holes like for a fence , a two-person auger is your best pet.
Augers can be extremely difficult for one person to handle and can even be dangerous if you are not familiar with the equipment. Rocky and heavy clay ground can be difficult to dig, even with a gas-powered auger. Get a good digging rock bar and post-hole diggers to help with this type of soil. Follow all safety guidelines when operating any machine. Avoid loose-fitting clothing and wear leather boots and eye and ear protection when operating.
Part 2. Wait for a dry day, if possible. Digging can be made very difficult if you're having to dig in rainy weather. If your hole is large enough, rain will eventually pool up at the bottom of your hole, which can pose its own challenges depending on the type and depth of hole you're going for. Moreover, it goes without saying that yard work is more enjoyable when it's done in reasonably good weather. Waiting for a good day is ultimately optional but it will have a major effect on the way you experience the work.
Frozen soil is very difficult to work with, so it's best to dig in months without extreme weather. Loosen the dirt with a mattock. Instead of going straight in with a shovel, you will save time and effort if you prep the area first with a mattock. A mattock is specifically designed to pierce topsoil and rip out roots. It takes 7. Manual excavation standard output rate for excavating in heavy soil for trenches 4 to 6 feet deep: 0.
It takes 8. Therefore, 0. It takes 0. It takes 1. Shown below are calculations for excavation production outputs for digging a 6 foot deep traditional grave and stormwater drywell using mechanized equipment in different types of soils.
We are going to estimate how long it takes to dig a 16 inch diameter x 6 ft deep hole using a truck-mounted A-frame hoist and power operated auger. This means it takes 4. Made with by Graphene Themes.
