The Rhine bridge Rees-Kalkar spans the Lower Rhine at river kilometer 838.65 west of Rees as part of the federal highway 67 the Rhine and on the right bank of the district road 3 from Rees to Reeserward . The road bridge is a double-hip cable - stayed bridge in the river area .
The bridge train is a total of 982.5 m long, has two lanes and walkways on both sides with a connection to the Rheinuferweg . The ramp inclines are 1.04%. The structure was erected between 1965 and 1967. It was opened to traffic on December 20, 1967. The bridge cost 23 million DM.
draft
The structure spans the Rhine and the foreland between the flood dams . In the river area, a stream opening at least 255 m wide and a clearance height of 9.1 m at the highest navigable water level had to be kept free. Under these conditions, a cable-stayed bridge with four rod-shaped pylons was chosen as the bridge construction over the Rhine. Hellmut Homberg made the planning .
construction
Superstructures
The bridge has foreshore bridges on both banks, on the left bank of the Rhine with four openings and 237.5 m length, on the right bank with five fields and 282.0 m length. There are continuous beams in the longitudinal direction , designed as a steel composite structure. In the transverse direction there are two-web T-beams with a construction height of 3.5 m. The main steel girders are 10.0 m apart. The reinforced concrete slab , prestressed in the transverse direction, has a maximum thickness of 50 cm above the main girders.
The 463 m long cable-stayed bridge has a steel superstructure with spans of 104 m in the two peripheral areas and 255 m in the main opening. In the transverse direction there is a 19.3 m wide plate beam section with an orthotropic carriageway slab . The main girders have a construction height of 3.5 m and are arranged on the outside at a distance of 18.8 m. Cross girders at a distance of 3.215 m connect the main girders and support the deck.
On each side of the bridge there are two pylon posts at a distance of 20.28 m next to the pavement board. They have steel box cross-sections with dimensions of 1.5 m wide and 2.24 m long. Its height from the top of the river pillar is 46.15 m. Ten individual ropes are anchored in the pylons on two sides at a distance of 2.47 m. The harp-shaped ropes have a diameter of 50 to 98 mm. They have an incline of 1: 2.5 and are anchored to the side of the main girders at a distance of 6.43 m.
Substructures and foundation
Two pylon posts each stand on a 21.61 m high, 24.3 m wide and 4.3 m thick river pillar, which is designed as a pillar disc made of reinforced concrete . This has a maximum 5.0 m thick caisson as a foundation. The foundation level is 7.0 m below the bottom of the Rhine. The piers of the approach bridges are founded on in-situ concrete piles with a diameter of 50 cm and a maximum length of 19 m. The abutments have a flat foundation .
Construction work
The river bridge was first installed in the side panels with auxiliary supports. This was followed by the cable-stayed cantilever assembly of the current field.
For the construction of the approach bridges, two auxiliary supports were installed in each field. During the removal of the auxiliary supports on the foreland bridge on the right bank of the Rhine, the bearing rollers slipped on a pillar on November 24, 1966, which led to a fall of a 95 m long superstructure section. People were not injured, but the restoration of the damaged bridge section delayed completion of the structure by half a year.
