The products and services offered cover the wide spectrum of geotechnical applications as well as applications in bridge-, structural- and civil-engineering through to underground mining. Also leading the market in geotechnical products, the company specialises in the use of sophisticated tensioning and anchoring systems.

The quality, accuracy and economic efficiency

Well-qualified employees, many years of experience, technical know-how and efficient customer support make ANP – SYSTEMS GmbH a competent partner and assure the highest quality, punctuality and economic efficiency.

GEOTECHNICAL SYSTEM

SAS thread bar systems have been successfully used for decades as micropiles, soil nails, rock and soil anchors, and tension ties in special geotechnical works and harbour construction.

The broad product range includes various systems featuring a variety of steel grades such as SAS 500/550, SAS 550/620, SAS 555/700, SAS 670/800, SAS 950/1050 and SAS 838/1035 as well as different types of corrosion protection systems: Galvanized, standard corrosion protection by means of a cement grout envelope, or durable double corrosion protection.

Our SAS systems can thus be used for a wide range of applications and be flexibly tailored to satisfy individual customer requirements and environmental conditions.
Numerous national and European approvals are proof of the reliability and efficiency of our thread bar systems in geotechnical engineering.

Our customers have already successfully installed our SAS micropiles, soil nails, rock and soil anchors, and tension ties in various projects worldwide, e.g. the new Gateway Bridge in Brisbane, Australia, Dubai Dry Dock, Al Salam Street in Abu Dhabi and Koge Harbour in Denmark.

On Balkan region we are using that kind of bar on slope support project like Mrtvica 1 , Mrtvica 2 on Serbian koridor 10 , Monte negro Highway Bar-Boljare , Port “Kostolac”-Serbia, ZGP-Sarajevo – Bosna Bridge etc..

ANCHORS

Anchors are always used in situations in which high tensile forces must be transferred into the ground. Typical applications include, for example, anchoring of excavation sheeting or retaining walls, slope and rock stabilisation or anchorings for bridge abutments or wind turbine masts.

The prestressing force applied to the anchor head using hydraulic equipment is introduced through the freely extensible prestressing tendon and the grout body into a load-bearing soil layer. The created anchoring force then acts actively on the anchored building component and the anchor does not require a displacement of the anchored component in order to become effective.

01. STRAND ANCHORS

Strand anchors consist of three main components: the anchor head, a steel tendon – divided into the bond section and free length – and the grout body.

The steel tendon is constructed from a number of 7-wire prestressing strands.

Features:

  • Nationally approved system with internal and external quality control
  • Can be closely matched to the required loads by selecting the number of strands, strand cross-section and steel grade
  • Longer anchor lengths can be produced without joints
  • Relatively low dead weight and small diameter
  • Ease of installation thanks to high anchor flexibility
  • Efficient to transport due to low space requirement for transport and storage (anchors are supplied coiled up)

Types available:

Temporary anchors

  • Temporary anchors (service life up to 2 years)
  • Temporary anchors for extended short-term use (service life 2-7 years)
  • Temporary anchors with removable free length

Permanent anchors (service life up to 100 years) in the steel grades (see tables for loads).

  • ST 1570/1770 0.60” (140 mm²)
  • ST 1570/1770 0.62” (150 mm²)
  • ST 1670/1860 0.60” (140 mm²)
  • ST 1670/1860 0.62” (150 mm²)

02. BAR ANCHORS

Bar anchors consist of three main components: the anchor head, a steel tendon – divided into the bond section and free length – and the grout body.

The steel tendon is a round steel bar with coarse, hot rolled thread ribs and can therefore be cut or joined at any desired point.

Features:

  • Nationally approved system with internal and external quality control
  • Well suited to transport and assembly conditions as delivered in parts with couplers
  • Simple tensioning, post-tensioning and releasing by means of screw anchoring
  • Simple to adapt to required length on site, e.g. with varying geological conditions (can be shortened by cutting or lengthened with a coupler)
  • Excellent bond between anchor rod and cement mortar thanks to threaded ribs
  • Can be closely matched to the required loads thanks to wide range of cross-sections and steel grades

 

Types available:

Temporary anchors

  • Temporary anchors (service life up to 2 years)
  • Temporary anchors for extended short-term use (service life 2-7 years)
  • Removable temporary anchors

Permanent anchors (service life up to 100 years)

in the steel grades below (see tables for diameters and loads)

  • S 670/800
  • S 950/1050

03. NAILS

The principle of soil nailing consists in installing reinforcements in the form of bars (soil nails) into the natural soil in order to increase the tensile and shear strength of the ground. This creates a monolithic compound structure whose load-bearing behaviour is similar to that of a gravity retaining wall loaded by external forces.

Typical uses include securing terraces or slope cuts and excavations and the stabilising of existing slopes and dams. The use as rock nails is a special application

HOLLOW-BAR NAILS –  Self drilling anchors

Features

  • Nationally approved system with internal and external quality control
  • Well suited to transport and assembly conditions thanks to delivery in parts with couplers
  • A wide selection of drill bits allows use in a wide range of soil types
  • Simple to adapt to required length on site, e.g. with varying geological conditions by using partial sections with couplers
  • Excellent bond between SHS-bar and cement mortar thanks to threaded ribs
  • Can be closely matched to the required loads thanks to wide range of cross-sections
  • Facilitates rapid building progress since drilling, installation and injection of the nail are carried out in a single operation

Types available:

Temporary nails

  • Temporary nails (service life up to 2 years)

Permanent nails

  • Semi-permanent nails, untreated, allowing for a soil-dependent corrosion rate (service life up to 50 years)
  • Semi-permanent nails, hot-dip galvanised, allowing for a soil-dependent corrosion rate (service life up to 50 years)
