The construction of the lock gate chamber of the outer head (number 1 in the picture) is scheduled for near completion in June. The diaphragm walls for the guard walls (numer 2 in the picture) will also be constructed this month, just like the flood defence between the new sea lock and the North Lock (number 3 in the picture). Outer head lock gate chamber This month, the outer head lock gate chamber will get close to its final dimensions. With its four metres thick floor, the underside of which lies at 5 metres below NAP (Amsterdam Ordnance Datum) and its six metres thick walls with a height of 17 metres above NAP, it surely is an impressive structure. Its total floor area is 26 by 80 metres. Once the required dimensions are reached, preparations can be made to sink the outer head lock gate chamber; this sinking operation is planned for later in the summer. https://www.hellenicshipp...
