Underwater Concrete Floors

Punching Shear in Deep Unreinforced Underwater Concrete Floors
Summary: In the relatively layered soft soil of the Netherlands, excavations very often consist of sheetpile walls and a concrete floor. A concrete floor is used because of the combination of the forces and water tightness. Due to the water level the concrete floor is constructed underwater. After construction of the concrete floor water can be drained out of the excavation. Because of the hydrostatical pressure, the concrete floor has to be anchored to the soil beneath with anchors or piles. Deep floors are constructed with an anchor, to keep the concrete floor in position. The small dimensions of the anchor related to the pile dimensions are subject of more examples related to the new Dutch recommendation.
