FAQ

Can you dig down straight always in the same diameter? I mean if you dig down in 10x10, will you end digging in 10x10?Only theoretically. Only serious answers.

Do you mean a rectangular, 10 x 10 hole? If so: No... at least not very deep. The excavation wall in most earth materials loses structural stability, and so excavation below some practical depth must be sloped to prevent failure. Even in a very competent rock, you cannot go very deep... I'm also neglecting the practicalities of the usual excavation equipment, like a backhoe or excavator, which are limited by the mechanical-arm length and geometry. I guess if you wanted to dig a 10 x 10 hole by HAND (or jackhammer or something), and you progressively reinforced the excavation walls above you as you went, then yes, I suppose you could go pretty deep. OSHA might have something to say about it, but I'm being theoretical as you asked, or semi-theoretical. Now, if you are DRILLING, so that your circular boring is 10 units (inches, feet, whatever) in diameter, then your hole stays more or less the same diameter, although there is wallow-out at the top, and maybe some small percentage of variability throughout- depending on the competence of the earth-material. Even then, you would case a deep boring to prevent wall-failure when you withdraw the augers. What you case it with depends upon your purpose- steel, PVC, cast in-place concrete, whatever. There are also cool boring machines that can drill lovely, round holes of consistent diameter through rock. There's probably plenty of other tech that I'm not experienced or familiar with with, too.

Hi, I'm in the Navy right now, but I really want to get into construction in the future when I get out, but I have no experience.I've heard that a good idea to get your foot in the door is to take a class to operate heavy equipment. I've researched a couple companies who do classes like that, like ATS, but most of them last months. I want to take classes like this, but I don't think I'll be able to take leave long enough to take one of these classes. Are there any other ways to get some lessons for equipment like dozers, graders, excavators, etc. in a shorter time period? Thanks.

How to adjust the flow of the main pump of Komatsu excavator?

Should be adjusted displacement, huh, huh?.The regulator has a adjustable bolt, this is a power regulating pump, clockwise is power up, of course, is small counterclockwiseFormula: power = pressure multiplied by the flow in the engine speed will not be under pressure in the pump output flow more (note that the two pump together, at 90 degrees for an adjustment value, can not be adjusted too much, otherwise it will be my car phenomenon)In the middle of the two pumps, there is also a big number of adjusting bolts, this is to adjust the maximum tilt angle of the pump swashplate. Similarly, the greater the swashplate tilt angle, the greater the displacement of the pump. This is clockwise, the angle becomes smaller, and the counterclockwise becomes larger. I hope my answer will be helpful to you.

1.The city of Centerville plans to dig a rectangular landfill. The landfill will have a base with dimensions 700ft by 200ft and a depth of 85ft.A)how many cubic feet of garbage will the landfill hold?C)what info do you need to determine how long the landfill can be used until it is full?D) Centerville hires an excavator to dig the hole for the landfill. How many cubic yards of dirt will he have to haul away?

I don't think the capacity of the landfill is as simple as the calculation of (700 x 200 x 85) cu ft. / (27 cu ft/ cu yd.) giving you a cubic yard volume. That calculation will only give you the volume of the hole. However landfill operation standards require daily cover of layers (lifts) of dirt - or other material as specified in the landfill permit. Therefore, the capacity for garbage will be less than the calculated volume of space excavated. Also, when garbage is placed in a landfill, it is compacted. How long a landfill will operate depends on daily loading. When the landfill is full, a final cover must be placed on it and maintained.

Which expert knows the excavator of this brand of Singway?

The Sinoway excavator you saw should be the excavator it bought, attached to its company's advertising.

Okay so I just got 3 fiddler crabs, 1 male and 2 females.I just bought a 10 gallon tank to keep them in, and I put sand in the tank on the land side and gravel on the water side, I started pouring water in and now the water is brown because of the sand.It's ZooMed Excavator clay burrowing substrate.I have 2 filters running in it right now to try and clear out the murkiness, but I want to know if it's okay to put the crabs in now, or if I should wait until the water is completely clear?I have a small pool with clear water in it that they can use but I am afraid of putting them in the tank because I don't know if they can swim in murky water.HELP PLEASE!

I'm sure they'll be fine, but wait until it clears up just to be safe.

Can you explain the negligence in this situation:Company X hires contractors to build a new building. They do not the “call before you dig” regulation, which provides:Before commencing or engaging in any . . . excavation . . . each excavator shall provide notice [by phone] of the location and date of the planned excavation. Its purpose is to give the government time to mark gas/electric lines. When digging the contracting company hits a gas pipe the contractor flies and hits one of my employees who breaks his leg. My employee sues the contracting company ... will he win because of the negligence of the contractor to follow protocol?

violation of a safety standard or procedure may be evidence of negligence, among other factors, provided the standard or rule was put in place to protect this type of victim from this type of harm. For instance, a fire lane outside a store is for emergency access by fire equipment. If you park in the fire lane and someone crashes into you, the fact that it's a fire land has NOTHING to do with either driver's negligence because there is no fire emergency and no fire apparatus involved.
