The company Teupe & Söhne Gerüstbau GmbH was awarded the contract for the erection of the working and protective scaffolds for the rehabilitation work, in particular for the scaffolding of the two bridge piers and the abutments for the dismantling of the superstructure as well as for the renewal of the supports. In addition, a winter-proof enclosure was ordered for the temporarily stored superstructures.

Task bridge pier

The working and protective scaffolds had to be attached to two viaduct piers. A particular difficulty arose in the area of the piers due to the one-sided slope towards the riverbed and the sloping structural geometry of the pier walls. This was solved by the construction and installation of spindle-type heavy-duty brackets that can be adjusted to the inclination of the structure. The heavy-duty brackets were erected as a circumferential working layer on a lattice girder ring. Access was provided by means of a stairway. The construction was carried out using modular scaffolds, which were founded on steel brackets. were founded.

The steel brackets were anchored to both viaduct piers with adhesive anchors. anchored.

Task superstructures

A winter-proof weather protection enclosure was also required for the superstructures on the assembly site. For this purpose, two movable protective enclosures (each measuring 9.00 m × 17.50 m) guided on rails were erected. They were designed as lateral modular scaffolding on steel construction-suitable bogies with a trapezoidal sheet metal roof. The enclosure was winter-proofed with Layher Protect panels and a supplementary winter construction tarpaulin. The enclosures had to be erected in accordance with ZTV-Ing for corrosion protection.

During the rehabilitation phase, a changed site situation arose. Due to further rehabilitation requirements, the enclosure had to be extended to a total length of 100 m and a stationary foundation had to be provided.

Service life of the scaffold structures:
August 2012 until June 2013
