Abstract: A method for forming a drilled pile wall in ground using a drilling device having a reamer and flushing with a medium to remove drilling waste during drilling, and non-rotating pipe piles equipped with interlocks. A vertical 1 hole is drilled while simultaneously placing a pipe pile in the drill hole. At least one subsequent vertical hole is drilled hole in the ground side by side with the drill hole while simultaneously placing a subsequent pipe pile in the subsequent drill hole while the interlocks of the subsequent pipe pile interlock with interlocks of the pipe pile to guide the subsequent pipe pile into the drill hole. Reinforcements are installed in the drill holes, concrete is cast into each pipe pile to form a concrete pile, and at least some of the pipe piles are lifted at least partly out of the drill hole after the concrete has been cast, but before the concrete has bonded rigid to form a unified watertight pile wall. The invention also relates to a pile wall.

Abstract: A method for mitigating flooding in existing coastal plain areas includes: A dyke (or dykes) is (are) set/built on seabed outside partial existing coastline of an existing coastal plain area to form an enclosed area; the enclosed area, together with the dyke(s), the reservoir inlet(s) and outlet(s), constitutes a reservoir for containing rainwater; or, part(s) of the enclosed area is (are) of a reclamation area (or reclamation areas). Before the start of forecast heavy rainfall or continuous rainfall, the water level in the reservoir is lowered in advance and the water level of water area for containing rainwater in the existing coastal plain is also pre-lowered, so effective storage capacity for containing rainwater against flooding caused by rainfall in the locality is substantially increased. The present invention is applicable for the flooding control works, reclamation works, roads and highways and their integrated works in existing coastal plain areas.

Abstract: An erosion control apparatus includes a flexible, container and a cord. The container includes a container upper side, a container lower side opposite the container upper side, a container trailing end, a container leading end opposite the container trailing end, and a container mouth toward the container leading end. The container mouth provides an opening to a container interior. The cord is attached between the container mouth and an attachment point toward the container trailing end. The cord draws the container mouth toward the container trailing end due to a length of the cord between the container mouth and the attachment point being shorter than a length of the container between the container mouth and the attachment point. The cord further draws the container mouth toward a closed position as sediment enters the container mouth, fills the container interior, and urges the container leading end away from the attachment point.

Abstract: A coupling between lead and extension pile segments of a driven piling. The extension segment has a formed end, an opposite driven end and a body extending therebetween. The formed end has an inner diameter equal to an outer diameter of an exposed end of the lead segment and greater than an outer diameter of the extension segment's body. The formed end has an initial length prior to coupling the extension and lead segments; the formed end undergoes secondary end forming when a driving force is applied, such that the formed end has a final length exceeding the initial length after the extension and lead segments are coupled. In some embodiments, the extension segment has an external ring portion positioned upstream of the formed end, and the exposed end of the lead segment is cold extruded into and through the external ring portion of the extension segment.
