Directional Boring

[itsalock69]

I bet we knocked out more footage than you guys!!!!!

[violeta0178]

why not set one up against steep mtn, turn down and set submersable pump and use as water well. Can it go 45 degrees thru fractured with a 4" drill for 3" case 200 ft?

[elvergillas23]

Vermeer sucks ditch wotch is the best 80/100

[Elton792]

@elvergillas23 ya i agree! i run the shit out of 7200hour Mach3 JT2720!... I Drill@pullback up to 600meters of 1.5/4"pipe a day... without a reamer!..Max pull with reamer ive pulled 10"pipe 200meters 7ft up to 20ft depending on ditches and gaslines etc.

that thing is tiny

my rig uses 6 and 5 eights pipe

[HuasoPodrido]

question: how does the machine curve the drilling pipe to go horizontal and then to rise and exit? it seems to be a solid drilling pipe.

[ptimmins]

@HuasoPodrido It has to do with how the drillhead rotates. You'll have to check wikipedia or google about it, as I didn't operate it.

[riclen123]

@HuasoPodrido the bit is slightly angled to one side and when pushed strait into the ground will turn one way or the other. the drill rods are not solid they have a channel that allows water or boring fluid to go to the head(bit). They track the head and can adjust depth and angles, to allow them to exit where they need to. The head has a beacon in it that is tracked by a hand held locator.

@HuasoPodrido it uses high prssure water and bit rotation to drill the hole

"D24x40 Series ll offers 4200 ft-lb (5694.4 Nm) of rotational torque and 24,000 lb (107 kN) of thrust/pullback" That is straight from the website. 4200lbs of spin 24000lbs thrust/pullback

[catch22locator]

You obviously are just a laborer.

[catch22locator]

actually you are wrong. 400lbs

[confederatepride85]

is that a 24x40 or a 36x50?

[junior2004hasz]

Yeah, might vary by manufacturer. Thanks pr0wned for your help.

[jfacey78]

HaHa, we got a million pound rig that would pull that machine thru a 4 inch hole

[ptimmins]

Awesome. Feel free to drop by and pull fiber for us anytime. Not my machine. :)

[bvacha20]

why don't he man up and put that stem in a lil faster, i bet there was nothing in the way. we did a 500 footer, pulled back in 2 hours with a 24X40 Navigator

[gaige814]

2 hrs for 500 ft thats sad. me an my operator can bust out 460ft in little over hour an be set up on our next shoot with a dw1220

[catch22locator]

If you new what you were talking about you would know that pullback time depends on the ground and whatis being pulled.

[hagueblake]

@gaige814 i highly doubt this. the most we ever did was 15 bores in a day. 3 inch pvc pipe. we didnt ream anything but we worked until 2 30 in the morning. the only way you did this in an hour is if you were pulling cable

[danMX96]

@gaige814 yehh cool

wipe your mouth mate your talking shit

[audio183]

I see the machines every day i sell parts for them from blades to flanges and iven tracks

[glassbuttons]

Thanks for the quick reply. Directional (or horizontal) boring / drilling is very cool. I am looking for companies who do such work in order to install a geothermal ground loop.

Straight down drilling is wildly expensive and present heat transfer inefficiencies.

Since the directional boring machines are not as expensive ($60K and up) as compared to drilling platforms (one contractor crowed about buying a $700K machine)the bids may be more competitive - and way, way cooler.

Do you know how deep and how far they were drilling, and what were they drilling under?

[ptimmins]

I'd estimate it went around 5 feet deep but I have no idea. They went across our parking lot, so it was about 300 feet? I suck at estimating distances. They were drilling under a standard parking lot.

I don't have a lot of good answers for these questions unfortunately, I was just the customer who was getting the fiber installed. I do know they pulled 3 conduits (in a bundle), and they pulled down the street, then across the lot, then penetrated the basement wall.

[ptimmins]

Got me, I was just the guy they were drilling for. I tried to stay out of the way. I remember the relative size of the unit, if you tell me what those are the dimensions of (the entire unit? The part between the yellow posts? The hopper full of pipe?)

[LoweJ82]

is that a 24 x 40?

[junior2004hasz]

Lowe - a 24 X 40 typically means 24,000 lbs of thrust/pullback force and 4,000 Lbs of rotary (drilling) torque. That nomenclature us typically used by most of the HDD manufacturers (Robbins/Universal, Vermeer, Ditch Witch, etc.)
