Work Detail

The Contract Includes The Execution Of Work For Different Parties. The Infrabel Part Mainly Consists Of Improving Water Management Between Bk 21,700 And 23,000 Of The L53 Railway Line (Put Van Malderen). Work To Improve Water Management Is Needed To Avoid Flooding Of The Rail Bed And Sliding Of The Embankment, Which Would Cause Delays For Trains. Indeed, The Platform Of Line L53 Between Pk 21 700 And Pk 23 000 Is Waterlogged.

Due To This Continuous Inflow Of Water Onto The Railway Platform, Effective Drainage Of The Track Is Impossible In The Current State Of Affairs Without Taking Significant Measures. Vertical Concrete Trenches Of Type Fv Will Therefore Be Installed To Improve The Buffer Capacity, Drainage Capacity And Flow From Affected Areas To Less Affected Areas. Retaining Structures (Sheet Pile Walls) Can Be Built In Certain Locations. In Addition, The Infrabel Part Includes Solutions For The Sliding Of The Embankment Along The L50a, Notably In Ternat And Wetteren.
