The nature of the proposed application usually gives a clue to the soil type. By determining the soil classification using geotechnical surveys or the Chance Soil Probe and a knowledge of the expected loads it is possible to decide on the most suitable anchor. In general the 49 and 60 round HS piles are for soils class 4 to 8.
The SS150 and SS175 square anchors and 89 round HS anchors work with soils from 8 to 3 and the rock version of the 89 round will penetrate soils up to class 1. Specific rock anchors perform well in class 0 soils but require a pre-drilled hole.
A wide range of termination components are produced to connect the pile to the load.
Class 1 soils are difficult to probe consistently and the ASTM blow count may be of questionable value
** It is advisable to install anchors deep enough, by the use of extensions, to penetrate a Class 5 or 6, underlying the Class 7&8 soils.
The column ‘probe values’, refers to torques measured using the Soil test probe available from ABC. This kit enables a single operator to perform a practical test to help determine anchor configurations and performance.
In general standard anchors can be used in soils from Class 8 up to Class 4. Rock anchors will give excellent results in Class 1 & 2 soils. However when subjected to tension loads care must be taken to ensure adequate depth of soil over the highest helix.
It is essential that regular testing of installed anchors is used as a back up to torque monitoring. This is the only way to ensure that installers and specifiers maintain confidence in the system. ABC can supply test equipment for quality control and insist on its use by qualified installers.
