What is the design and development of anchor drilling rigs?

The design and development of anchor drilling rigs involve a high degree of demand in a variety of industry sectors, from field investigations and in-depth research, combined with modern new hydraulic principles, to create intelligent mechanized production equipment.

How do you install a rock anchor?

The Rock Anchor is tightened along the anchor shaft to expand the resistance wedges into the rock. To install anchor, drill a 12" deep hole in solid rock, put anchor in hole, turn rod until anchor expands and wedges in the hole. Anchor consists of two Malleable castings and a Triple Eye Anchor Rod. Anchor diameter is 2-1/4".

What is the size of an anchor Rod?

Anchor consists of two Malleable castings and a Triple Eye Anchor Rod. Anchor diameter is 2-1/4". Anchor size expanded is 3-1/8". Hole diameter is 2-3/8". The harder the pull on the rod, the tighter it wedges into the rock.

What is a bonded rock & soil anchor?

Williams standard grout bonded rock & soil anchors consist of a plain or epoxy coated bar, grouted in an oversized drill hole. Centralizers should be used to assure good grout cover (approximately 25 mm) around the bar.

Do anchors need corrosion protection?

Where anchors will penetrate aggressive soils that are low in pH value (<5.5) and high in sulfate, additional corrosion protection may be desirable. The degree of protection should be matched against the aggressivity of the environment and the expected life of the anchorage system.
