Ground Anchors

Steel mechanical ground anchors are used as an anchoring system to restrain sheet pile or steel beams against the lateral loads applied when face excavation occurs. The anchors may be installed using an excavator mounted hydraulic impactor or an airtrack drill rig.

The mechanical ground anchors installed by Compile are fabricated steel units, driven horizontally into the ground through penetrations cut in the sheetpile. The anchor itself features a bearing plate that rotates when stressed.

The ground anchor has either a threaded steel rod or a braided steel flexible strand attached to it when driven, connecting the anchor to the sheet pile or beam to be positioned.

A profiled face plate is placed over the anchor strand with a tapered barrel and wedge system to lock-off the anchor at the required tension or load.

Grouted ground anchors are structural elements where a grout body is produced in the subsoil by injecting grouting mortar around the rear part of a steel tendon. The grout body is connected by way of the steel tendon and the anchor head to the structure or the rock section to be anchored.

Any load to be taken up by the grouted anchor is passed into the subsoil not over the entire length of the anchor but only in the area of the grout body. The steel tendon section where the anchor is free to expand is the free tendon length.
