Helical Pile Job
Hello everyone has been a long time have been busy and this site seems a bit slow from my computer so have not been on for a while. Here is an addition we are doing on a toll plaza we have to install helical pull down piles 60 kip / 50' min piles. We ended up install 1 3/4" helical piles with A 5" grout colomun about 75' deep with a ultimate capicity of 150 kip min.

Nac what in the world does "helical pull down piles 60 kip / 50' min piles. We ended up install 1 3/4" helical piles with A 5" grout colomun about 75' deep with a ultimate capicity of 150 kip min." mean?
Could you explain what exactly you are doing? |

Re: Helical Pile Job
I did a helical pier job to support a foundation of a house so we could dig out and put in a home theatre. Ruskent they are giant screws put into the ground used as piers.

Re: Helical Pile Job
Helical piles seem to be very common in the NY/NJ area, and are nearly unheard of in other areas. Do you rent the attachment that winds them in, with the pressure gauge, or do you own that? It looks brand new. What's something like that run?

Re: Helical Pile Job
the drive head is a 20,000 ft lb unit cost about $8500 with out the quick attach bracket and hoses. The torque data logger is about $4000 and I had to wire and plumb every thing myself.

Re: Helical Pile Job

Re: Helical Pile Job
Well we are installing helical anchors 73' deep up the 12,303 fl lbs of torque. I would say I am pussing the limit of the mini because at that torque the machine want to swing by itself. I am looking for a Komatsu pc-78 or a Deere 85D in the future to mount the auger motor on.

Re: Helical Pile Job
Yes the water table is a problem also here in many jobs you have to case the hole which can get expensive really fast. I am also looking to get into Titan anchors it is a hollow anchor that is drilled while being pressure grouted
