    摘要： A precast, prestressed concrete tank and method that facilitates construction of a primary inner tank within a secondary outer tank, and which permits for the construction of the primary inner tank after the secondary outer tank has been erected, but without requiring insertion through a top of the secondary outer tank, or by tunneling underneath the secondary outer tank, is disclosed. The primary inner tank has an inner wall and the secondary outer tank has an outer wall (precast, prestressed concrete) and wire windings. The primary inner tank is disposed inside of the secondary outer tank. The secondary outer tank has a plurality of first precast outer wall panels, and a temporary construction opening frame. The temporary construction opening frame defines an access doorway during construction of the tank. The temporary construction opening frame is disposed on a foundation base slab.

    摘要： A concrete storage tank structure comprises a tank including a floor slab having a periphery and a wall having inner and outer faces extending upwardly from the floor slab at a position adjacent the periphery of the latter. The tank structure further includes a shear pad extending outwardly away from the tank from a position adjacent a lower portion of the outer face of the wall. The shear pad and the tank are positioned relative to one another in such a way that a space is provided therebetween and a number of elongated flexible connecting elements are arranged so as to extend through the space in interconnecting relationship relative to the shear pad and the tank. A strip of resilient neoprene elastomeric material is disposed in the space. The shear pad is thus flexibly attached to the tank in such a way that the forces imposed on the wall of the tank by the shear pad during movement of the tank during use are minimized.

    摘要： The present invention is directed to improved tank or containment vessels and processes and apparatus for their construction. The tanks or containment vessels usually consist of circular walls resting on a base and a dome supported by the walls. The dome of the subject prestressed tank is formed by deploying or creating a membrane on the base, applying one or more layers of rigidifying material (and prestressing or reinforcing material if needed) on the membrane and then forming said membrane into a dome before the rigidifying material sets by the selective introduction of compressed air at appropriate locations between the base and the membrane. The hardening of the rigidifying material results in a composite preformed rigid roof or dome having a membrane liner and an overlay of composite construction. Once the walls are created, air pressure can be further utilized to raise this preformed composite dome upward to a predetermined height after which it is fastened to the walls. An appropriate air seal may be used to prevent excessive leakage of air between the walls and the dome and to assist in the raising of the dome. Utilizing this air cushion procedure to raise the dome to its proper location, eliminates the need of scaffolding and other costly support structures. Integral seismic anchors may be also used to complete the construction process to protect the structure against earthquakes and other tremors by anchoring the dome to the tank walls and the tank walls to the base in a manner whereby the seismic forces are translated parallel to the wall instead of radially to the wall.

    摘要： An improved dome structure on a base is disclosed comprising, in the preferred embodiment, of a membrane sandwiched between layers of rigidifying material such as shotcrete or reinforced composite which also serve to embed radial wires and circumferential tensioned prestressing. Various types of circumferential tensioned prestressing can be applied to minimize bursting stresses and can consist of steel wire as well as fiber or steel-reinforced tape. Further layers of rigidifying material can then be applied over the circumferential prestressing as a final protection and cover. The radial wires can contain spacers or hooks to preclude the circumferential prestressing from riding up on the structure. The lower portion of the dome can include a reverse curvature to minimize stresses and stabilize the structure. The rigidifying material may be composite which can be hardened by light curing. A second outer membrane can also be used for weather protection.

    摘要： The present invention is directed to improved tank structures and the processes and apparatus for their construction. The walls of the prestressed tank are formed by inflating a membrane, applying one or more layers of rigidifying material on said membrane and then prestressing the walls by circumferentially wrapping prestressing material to minimize the tension in the rigidifying material when subjected to loading. In another embodiment wall forms are placed inwardly of said membrane to aid in the forming and support of the walls under circumferential prestresing. In the best mode of the invention, the walls are of reinforced plastic, fiber, or shortcrete and resin sandwich composite construction. Seismic countermeasures designed to minimize vertical or radical bending stresses in the wall or dome shell may also be used to protect the structure against earthquakes and other tremors, by anchoring said wall or dome shell to their base in a manner whereby horizontal seismic forces are distributed circumferentially around the wall or dome shell.
