Rock and Soil Anchors

CTS Rock- and Soil anchors are the current state of practice in the Geo-Support field. Our innovative solutions and systems have been widely accepted by Geotechnical-, Civil- and Structural Engineers as well as Governmental Agencies and Private Owners.

CTS has focused most of his developments improving Strand- and Bar-Anchor systems, i.e. corrosion protection and permanent monitoring.
 

Applications:

Tie Down & Tie Back Anchors in rock and solid grounds
(permanent & temporary)

Features:

High Strength, Very Flexible, Very Ductile

Corrosion Protection:

None, Class II (Single), Class I (Multiple)

Confectioning:

Single Strand, Multiple Strand
(no theoretical limit, largest anchor manufactured: 60 Strand)

Length:

No theoretical Limit

Advantages:

• Only small storage and assembly areas required
• Shop fabrication of corrosion protection
• High yield point (1570 N/mm²=227 ksi)
• Low E-modulus (200,000 N/mm²=29,000 ksi)
• Inherent redundancy due to more than one tension element
• Installation under extremely tight space conditions possible

Max. Design Loads:

• Ground Anchors: 160 kN=36 kips - 2400 kN=540 kips
• Rock Anchors: 156.4 kN=35.2kips (per strand)

Material:

meets the ASTM A-416 Specifications

Applications:

Micro Piles, Soil Nails, Tie Down & Tie Back Anchors in rock and solid grounds, Soil Nails, Seismic Applications and as Form Ties
(permanent & temporary)

Features:

• Weldable (Mukusol Bar)
• Very ductile
• (All)-Thread Bars

Corrosion Protection:

None, Class II (Single), Class I (Double)

Confectioning:

Diameters: 5/8" (15 mm) to 2 1/2" (64 mm)

Length:

Length: Custom specification, Bars can be coupled

Design Loads:

120 kN (27 kips) - 2074.3 kN (466.8 kips)

Material:

Meets or exceeds ASTM A 722 or ASTM A 615

Applications:

Micro Piles Soil Nails, Tie Down & Tie Back Anchors in difficult ground conditions like weathered and decomposed rock, round gravel, sand and clayey soils (permanent & temporary)

Features:

• Utilization of steel drill as anchor.
• Economically priced on-time use drill rod and drill bit.
• Utilization of the steel drill as grouting conduit for filling. the annulus from the bottom up.
• Choices of high quality steel.
• Titan-INOX ferritic-austenitic stainless steel for permanent anchors with a life span of 50 years and more.
• Threads on the rods are formed much like the ribs on a reinforcing bar (fabricated according to DIN 488).
• Continuous threads guarantee the IBO-Titan anchor can be cut or coupled anywhere along its length.

Corrosion Protection:

Single, Double

Length:

Single IBO-Titan rods are generally 3 m in length.

There is no principal limit to anchor length; rods can be coupled until the desired length is reached.

Advantages:

• No cased in boring.
• Minimal space requirements for installation.
• Installation technique adapts well to awkward shapes.
• High grout pressures can be achieved.
• Improved anchoring capacities and reduced settlement.
• Minimum grout cover, maximum corrosion protection
• Higher shear resistance than a solid rod of same cross section
• Very economical

Design Loads:

34.6 kips (154 kN) - 544.6 kips (2422 kN) 

Standard Stock Items:

IBO-Titan 30/16, R32/20, R38/17 40/20 40/16 73/53 (outer/inner Diameter in mm).

Certificates:

The Material has been tested by the Bundesamt fuer Materialforschung (BAM, Federal Goverment Institute for Material Research) Berlin, Germany. Report No. 1.3/12279 dd. 9. 6. 1992 on corrosion resistance of IBO-Titan INOX anchors.
