[norrodbh]

OK, maybe one more before & after

 

[norrodbh]

The site is starting to come around. I have to install drainage for the foot of the hill, and cut some diversion trenches up top.

Then I'll run a power rake over it all to finish it.

For someone killing time, all the photos are here. more photos

Here are some pics of the rock removal.

What is the attachment on the mini X some kind of rock drill?

 

[Ford LT-9000]

That attachment NAC has on his machine is a common tool now for us in rock country the days are almost gone when hand drilling is done. There are contractors with 40 ton excavators with drill attachment on them with the dust vacuum system. The drill on some machine is hydraulic powered instead of air power. One blasting contractor has a drill rig its based on a skid steer but its not a skid steer loader. I don't know the brand name but it drills holes faster than any hand operated air drill ever could.

I did quite abit of drilling its not a easy job its hard on the back and it shakes the crap out of you.

I bet you that drill NAC has will pay for itself in no time drilling holes for blasting or drilling holes for anchoring or pinning foundations etc.

Yes it is a rock drill attachment. here is a pic. Ford LT-9000 the machine you are talking about is called a commando it cost close to 200,000.00 brand new.

You guys sure are blessed with a lot of rock in those parts! Seems like all the pics you post are rock breaking jobs.

On that drill, are you running it through a compressor? In one pic, it looks like there's a yellow hose running off the side of the machine?

 

[Nac]

Yes the drifter motor and air flush is off a 300 CFM air compressor. The down pressure and drill position is of the aux. hydraulic lines that go into a control box in the cab.

Pretty sweet setup.

Hil slide area

Here is what I have been working on. Could use Squizzy's help on this one.
The hill was cut into when the gerage was built about 12 years ago. The owner removed 1 rock about 2' in dia. at the base to get a wheel barrow by and started the mess. The next rain the hill side gave way as you can see in the first picture. He called me and like a fool I accepted the chalange. These 3 pictures take you 2/3 the way through the project. I refuse to work on the job when it is raining or for atleast 4 dayes after it stops. Here that is like non existant this year. I have about 40 hours into the project so far.
And Yes that is gray clay under the topsoil. Very hard untill wet then it flows by itself. There is going to be another layer of block back 6' from the lower ones which are 1' high each or a 4' high wall. Blocks are 2' wide 2' deep and 1' high, and weigh 560 lb each. 2" shot rock is compacted behind the wall with 4" drain tile at the bottom. Total when compleated will be just under 100 blocks in the 2 walls.

so what are you putting into the drill holes bentimite? (spelling) or do you drill them then call the blaster to set of explosive?

 

[Squizzy246B]

Hey Dwan, that looks like a bloody good job you are doing there in those conditions...but be careful about developing a reputation for doing the difficult jobs that nobody else wants to touch You end up with one leg longer than the other from standing on the side of steep hills all day:yup

On this job I am mostly using a Darda Hydraulic splitter. But also used some Damite (expansive grout)

 

[CascadeScaper]

So with the Damite do you use the drill and just pour that stuff in the hole and watch it work?

 

[Squizzy246B]

But also used some Damite (expansive grout)

We tend to use Dynamite:bouncegri back in my Navy days we called this expanding bait

 

[Dwan Hall]

Expanding bait = hand gernade

 

[Nac]

No with Damite after drilling the holes you blow them out and mix the Damite and by the next morning it schould be alll fractured. It is a great product but it takes time.
