Abstract: A bulkhead is illustrated with sockets through the top deck and an intermediate platform to provide a box-frame structural strength to the bulkhead and to receive pool attachments for swimming activities, such as diving platforms or water polo goals. Another invention is the provision of tongue members for joining separate sections of a bulkhead which is assembled together at the swimming pool site. These tongue members can be longitudinal tongue members protruding from one or the other of the sections or they can be transverse tongue members which are on each section and are secured together. There is also an invention of access ports through both the top deck and the intermediate platform of a hollow swimming pool bulkhead for providing access to the interior of the bulkhead.

Abstract: A swimming pool bulkhead is provided with sets of transversely spaced buoyancy chambers for providing stability against rotation about the lengthwise axis of the bulkhead when the chambers are inflated. The bulkhead is made of two separate short sections which are transported separately and bolted together at the pool.
