Belgium/ Merksem – The Albert Canal, which connects the Meuse and the industrial areas of Liège with the Antwerp maritime port, stretches along for nearly 130 km, making it one of the main arteries for transporting goods by water in Belgium. In order to increase the capacity of the waterway to accommodate more and also larger ships, extensive expansion work has been taking place along the channel line.
As part of this project, Herbosch-Kiere nv of Beveren, a company belonging to the Eiffage Group, recently built a new 260-meter quay wall along the canal. Herbosch-Kiere was commissioned as the general contractor to carry out the sheet piling, reinforced concrete and anchor work for the construction phase near the port of Antwerp.
A KLEMM anchor drilling machine type KR 805-3G was used to make a total of 129 strand anchors using the overburden drilling method. In combination with the powerful KD 2524 hydraulic hammer, the flexible kinematics of the machine meant that it could be used for all work carried out by a pontoon and upstream filled earth areas.
Since access on the water side was not always possible, some of the anchors had to be executed from the embankment with the drill mast positioned over the water. For this purpose, a KLEMM KA162 drilling attachment system operated on a hydraulic excavator weighing approx. 30 t was selected.
The KLEMM handling system HBR 122 made it possible to efficiently handle the pipe pairings weighing up to 140 kg combined with a high degree of occupational safety for the operating personnel.
The project, which was commissioned by the Flemish Waterway Administration (De Vlaamse Waterweg), was successfully completed in summer 2019.
