The CONDOR MF EARTH-RETAINING system can be used for singlefaced wall castings up to a maximum height of 8.40 m. The earth-retaining system comprises the elements A - B - C and can be fitted in various combinations: A+B; B+C; A+B+C (diagrams on next page). The height of the panels can therefore reach 8.40m with a combination of 3 x 2.40m + 1.20m. The maximum pressure of the concrete is 50 kN/m2*. The elements connect to each other and to the Comax panel using anchoring accessories. The dimensions of the single-face allow it to be transported both by vehicles and containers.

2. Combinations

The elements of the CONDOR earth retaining system are connected to castings using suitable attachments. To assemble the system, the Comax casting is laid out and suitably braced strut elements are placed on top of it. The entire system is lifted and positioned as a single, temporary equipment unit.

Warnings

If the system is moved with a crane attachment points must be used for lifting vehicles. These points must be appropriately provided on the earth retaining elements. Check the maximum capacity of the lifting accessories. Never attach lifting slings to castings. Always attach slings to attachment points on the earth retaining unit.

3. Single-faced wall assembly stages

The concrete pushes the trellis elements of the single-faced 6 wall via the casting. The trellis elements are securely anchored to the support surface with anchored bars embedded at 45n° in the wall foundations. Distances x and y must allow the anchored bars to remain in the free area behind the casting; y is inversely proportional to x.

Types of anchoring

The types of anchoring vary according to the traction force that acts on the point at which the system is anchored to the ground: the admissible load for the DW15 anchorage system is 90 kN; for DW20 it is 150 kN; for DW26 it is 250 kN. There are two anchorage points to distribute the traction force across the two rods.

Positioning reusable anchorage rods:
- assembling the anchorage with a v-shaped positioning device, pvc pipe and mounting cone;
- dismantling the mounting cone;
- tightening the rod junction element and anchoring rod;
- after casting, remove the rod and the rod junction element, close the anchorage hole.
Positioning disposable anchorage rods:
- fitting the anchorage with a v-shaped positioning device and mounting cone;
- dismantling the mounting cone;
- tightening the rod junction element and anchoring rod;
- after casting, extract the rod junction element;
- close the anchorage hole.
N.B. The anchorage must not interfere with the casting.
