Underplate Protection
The purpose of the under plate protection is to provide an effective connection/protection between the sheath of the free length and the anchorage.

The DD-SF spherical support allows the installation of temporary and permanent ground anchors. The spherical cap rests on a support that transfers the force to the bulkhead, thus reducing the load transfer coefficient.
In an aggressive environment, the anchor head must be immediately protected, both with temporary and with permanent anchors. The protection inside the heat provides an efficient connection with the free length protection, in order to protect the small reinforcement section below and through the bearing plate.
DD-RC connections are made for corrugated sheaths. They allow to connect sheaths by adapting different diameters and with enlargements and narrowings. They can be screwed on corrugated sheaths with the following diameter: 75 mm, 90 mm and 110 mm, they are provided on their length with a 100 mm thread every 500 mm.
The DE150KN load cell is designed for the installation on ground anchors, and in particular on single strands anchored to plates. Their shape and dimensions make these cells suitable for the installation on an elementary strand under the anchoring bush.
DD-DS internal spacers are designed to allow the anchor in the foundation to guarantee the sinusoid effect of the strands inside the corrugated sheaths, as well as the separation of the strands and tubes necessary for the grouting and vent activity. Internal spacers are only installed in the foundation.
All permanent anchors have an end cap connected to the corrugated protection sheath. The plastic end cap is fixed to the corrugated sheath with a suitable tape to secure it and ease the insertion into the drilling hole.

DD0015-CV bush covers guarantee protection against corrosion on elementary anchorages, both on temporary and on permanent anchors. DD0015-CV are particularly effective on applications with temporary anchors in several and subjected to several tensioning phases, as they protect: bush, wedge and strand against corrosion, making re-tensioning easier.
The double piston for I.R.S. groutings type XG27-600is produced with a highly resistant spring, allowing flexibility; it compensates for the natural deviations of the valvate tube and guarantees selective grouting (I.R.S.) of the manchette valves up to a max. pressure of 46 bar.
