Tunnel Eemsgolaan Groningen

Work on the future junction Peizerweg – Eemsgolaan Groningen. For this project Qceas has delivered, pumped and applied the underwater concrete for the whole tunnel. In total it was 2150m3 of underwater concrete. Prior to this work, Qceas cleaned the bottom of the excavation to remove the excess sludge, the anchoring elements were prepared and the sheet pile is cleaned at the height of the under water concrete.

The Blue Vein Tilburg

A flooded Street after heavy rainfall. In the summer of 2014 it was still happening in Tilburg City. With the construction of ‘the blue vein’ that is going to change. In order to address water pollution caused by heavy downpours, the municipality addressed some spots in Tilburg called the blue veins. A blue vein is an additional drains for the drainage of excess rainwater. These veins are an extensive system of underground pipes meant to get rid of excessive water. In this case it concerns a route of no less than 3.2 km in length. Through a closed front bore the main contractor drills this vein. At the height of the Hasselt roundabout Qceas carried out the preparatory diving activities and the underwater concrete. From this place drilling for the blue veins has started. The underground hole for the new sewer will run until the junction with the Kwaadeindstraat. If all goes well, it takes drilling until August 2016. At the end of the line, at the junction of the Middle Brabantweg with the Burgemeester Bechtweg eventually comes a new terminal pumping station.

Tunnel Zevenaar – Doetinchem

Qceas has recently completed a project to place an underwater frame to secure the building pit. The activities included the welding of consoles underwater for support of the rafters. Then the purlins are mounted on these consoles. This construction is carried out on both sides of the building pit. In the end 2 jacks between the purlins are placed which then were fixed with cement. All these constructions are carried out by Qceas under water without any visibility!
