The impression of a mighty tree has inspired us. It has a network of large and small roots, which support and anchor it into the soil without the need for a concrete foundation.

The roots transfer external, vertical and horizontal static and dynamic forces, moments and shocks which the tree has to absorb.

This network of roots enable the tree to withstand wind, snow loads and earthquakes. On the one hand the roots interlock with the soil, on the other they convert the soil to a monolithic structure (root ball). As the tree grows, the roots grow with it to ensure that it has a firm anchorage sufficient for its size. How the tree calculates the size and complexity of the roots needed to provide stability is unknown. What is known is that a composite material is being created to protect the tree and assure its longevity.

We have learned from the tree; to take the soil into consideration for construction, to use resources economically, to improve and reinforce the soil.

These considerations in foundation technology were recognised by Dr. F. Lizzi in 1952 when he called his micro piles "root piles" (Pali Radice)

TITAN Injection Bore Anchors are an intelligent tool for construction.They have been used for constructing root or anchor piles since 1984
Just "one visit to the job" (covered by patents DE 3400182, DE 3828335)

1.	Utilization of a drill steel as an anchor From the static point of view, a tube is superior to a soild rod of the same cross sectional area with respect to bending moment, shear resistance and surface bond/fricition
2.	Creation of an economically priced one-time use drill rod and drill bit  This technique eliminates two labor intensive elements namely required for anchor installations They are: the insertion of the anchor itself and the removal of the drill rod and the casing.Consenquently smaller drill rings can be used, the  amount of grout is reduced and substantial labor savings are achieved.
3.	Utilization of the drill steel as grouting conduit for filling the annulus from the bottom-up  This guarantees a positive complete filling of the annulus as well as all fissures and cracks.This method is much easier than using additional tubes for grouting, air vents and post-grouting.
4.	The choice of a high quality structural  steel offers high notch toughness > 39 J in comparison to high tensile rods or strands having > 15 J or glass fibre anchors. This steel is not affected by hydrogen embrittlement or by post rolling heat treatment. In addition, it offers high shear resistance.
5.	The use of a ferritic-austenitic stainless steel TITAN-INOX  for permanent anchors with a life span of 50 years and more This material (no. 14462) is equivalent to "double corrosion" DIN 50929 part 3 - likeliness of corrosion in construction parts and underwater construction. Working with this TITAN-INOX material is much easier than with the standard permanent anchors which are surrounded by grout in corrugated plastic tube, especially as far as extension (coupling) and the preparation for the anchor head are concerned.
6.	The threads on the TITAN anchors are formed much like the ribs on a reinforcing bar fabricated  according to DIN 488 the deep TITAN threads result in 2.4-times higher bond friction compared to standard drill steel coil-threads of R 32 (1-1/4") or R 38 (1-1/2")
7.	Continuous threads guarantee the TITAN anchor can be cut or coupled anywhere along its length Cutting, extending, pre-stressing and load releasing on the anchor are possible. A thread pitch of 6° eliminates the need for counter nuts at each coupling.

Ischebeck TITAN's ground engineering techniques provide solutions for anchor, soil nail, pile or rock bolt applications, with a wide variety of bar sizes, drill bits and accessories available to suit every
requirement. The versatility of the Ischebeck TITAN solution is evident in the number and variety of projects on
which it has been used, often providing a more economic, efficient and effective alternative to traditional construction and engineering methods.

Ischebeck TITAN micropiles comply with DIN EN 14199 micropiles.

Ischebeck TITAN injection piles are ideal for use as tension piles, mini piles and root piles (pali radice) in micropiling situations. Ischebeck TITAN micropiles consist of a continuously threaded, hollow stem steel reinforcement tendon combined with an OPC grout body of a minimum 25 N/mm2 strength. The profiled surface of the grout
body transfers tension and/or compression forces into the ground.

Advantages over conventional piles

• Works in compression and tension
• Does not require temporary casing
• Improved mechanical ground/grout interaction reduces overall depth
• Dramatically increased production rates
• Lightweight rotary percussive drilling equipment
• Installed in confined spaces
• Permits top down jet grouting in saturated clays and silts complete with re-bar
• Perfect as pali radice for invisible structural repairs
• Remote de-coupling unit facilitates underwater near shore piling from barges or jack leg platforms
• Self drilling micropiles provide a range of working loads from 110kN to 3,000 kN
• Minimal noise
• Low vibration
• Minimal spoil

 

 

 

Ischebeck TITAN Anchor Piles can be used wherever a traditional ground anchor is being considered and provide a rapid, efficient method of installing tie back anchors in one visit to the hole.

All Ischebeck TITAN bars use the same installation technique and, with a range of 100kN to 3000kN, only the drilling rigs get bigger.

The Advantages:

• 2 to 3 times greater productivity than conventional systems
• Grout injection technique continually scours and flushes the sides of the drill hole, enhancing mechanical connection to the soil.
• No casing is required in collapsing ground conditions.
• Ischebeck TITAN bars are made from a high quality, high yield, low carbon steel, which does not suffer from hydrogen embrittlement or stress corrosion cracking.
• The grout body provides simple, permanent corrosion protection.
• Very low creep characteristics of the bar obviate the need for re-stressing.
• Can be extended by couplings on site if ground conditions do not match the
  S.I. information.

 

Soil nailing is an efficient, effective and economical method of earth
reinforcement, which allows a controlled improvement of the natural stability of the soil. TITAN soil nails provide friction, shear and tension strength in loose materials, combining all into a new monolithic structure.

Soil nailing consists of 3 basic elements:

• Existing soils or weathered rock.
• TITAN rotary grouted, self drilling soil nails.
• Surface treatment with reinforced shotcrete, geotextile mesh or tensioned wire nets on slopes to 70 degrees.

Advantages of soil nailing

• Installation is practically free from vibration.
• Drill rigs can install soil nails at all angles.
• As there is no requirement to case line the drill hole, most drill rigs installing TITAN soil nails are smaller and can cope well with slopes and confined spaces.
• Soil nailing offers the opportunity to produce an environmentally friendly but technically safe "green wall" solution, often less expensive than traditional back anchored retaining walls.

 

Rock bolts are commonly used throughout the civil engineering and tunnelling industries (especially NATM). They are used to improve the stability and load bearing characteristics of a rock mass. In the tunneling industry, Ischebeck TITAN rock bolts are used for horizontal fore-poling, slope stabilisation at the tunnel portal and for anchoring large section tunnels with high side walls.

 

The advantages

• Greater productivity than conventional systems
• No casing required in collapsing ground conditions
• Unlimited service life
• Composed of high yield, low carbon steel
• Suitable for all ground conditions
• Can be either passive or stressed
