General Construction Procedure

Well foundations may be constructed in slipways on barges, or on sand islands. The ones constructed in slipways are launched and towed to their final location by floating. False bottoms made of wood are necessary for open or pneumatic well foundations floated to position. Guide piles are commonly used for sinking the first few lifts of well foundations.

Well foundations are sunk by their own weight while the soil is being excavated from the dredging wells. As sinking operation progresses, additional sections (lifts) are successively installed. Upon reaching its final depth, the bottom of the well foundation is plugged by a concrete seal. In open well foundations, this plug is placed in water. The
