New construction of a spun concrete radio mast

Since the summer, we have been looking for a suitable mobile phone mast location for the construction of our product named "FUCHS Pfote". In particular, the local conditions such as accessibility, access roads and ground conditions ultimately tipped the scales for Frimmersdorf, around 40 kilometers southwest of Düsseldorf, explained project manager Joachim Wach from our West branch. We had already planned the construction of a 40-meter-high spun concrete system mast for a customer there.

Installation of foundation and radio mast

The extensive work for the preparation of the construction site began at the beginning of October. Within a week, a sheet piling of the approx. 8.5 x 8.5 meter excavation pit was built. The particular challenge was to compact the ground and produce a fine grade of grit without any slope so that the "FUCHS Pfote" could be placed exactly vertically. At the end of October, the 130-tonne mobile crane lifted the two halves of the foundation, our fitters tightened the tendons and attached the bracing to the quiver head area. Subsequently, we filled the potting joint with fast-tightening grout, which was supplied by our FUCHS precast plant. Now the mast parts came into position. A concrete pump with ready-mixed concrete filled the horizontal potting joint of the precast elements, the annular gap of the foundation quiver and the mast base. A little later, we were able to loosen the tension in the head area, fill the excavation pit and set the precast foundations.
