Described herein are apparatus, systems and methods useful in forming vertical structures.

A system and method for storing molten sulfur includes a reinforced concrete vessel, the reinforced concrete vessel being subterranean. The vessel has a floor that is a raft footing formed of reinforced concrete and has a floor interior surface. The vessel also has a ceiling that is a slab of reinforced concrete and has a ceiling interior surface. Sidewalls of the vessel extend between the floor and the ceiling and are formed of reinforced concrete, each sidewall having a sidewall interior surface. A liner is bonded to the floor interior surface, the ceiling interior surface, and each sidewall interior surface. The liner formed of an epoxy vinyl ester resin, and a glass fiber sheet embedded in the epoxy vinyl ester resin.

The invention concerns a floor-to-wall joint connection BearStop device for providing both a water-tight seal, as well as load-bearing and flexibility between two closely abutting or adjacent structures, such as the wall and foundation of a storage tank. Embodiments also provide motion or sliding capabilities to accommodate expansion and contraction in the joint area between the wall and the foundation. A knee section provides a testing channel usable for testing the integrity of the seal.

A free-standing liner unit (1) is formed by integrating a planar outer tank liner plate (2), a planar secondary barrier plate (3), and a cold insulator layer (4) that is interposed between the outer tank liner plate (2) and the secondary barrier plate (3) into a single unit. According to this free-standing liner unit (1), when building a tank, it is possible to shorten the construction period by performing the formation of the outer tank shell plates and the formation of the tank internal structure concurrently with each other, and to achieve an improvement in the handleability of the free-standing liner unit (1).

A cryogenic liquid tank (1) includes a reservoir (5) that includes a bottom portion (5a, 5a1, or 5a2) and a side wall (5b), a support portion (4) that supports the reservoir (5), and an intermediate member (10) that is provided between the reservoir (5) and the support portion (4). The support portion (4) includes an outer support portion (4b) which supports the side wall (5b), and an inner support portion (4a) which is disposed to be adjacent to an inner side of the outer support portion (4b), includes a heat insulating layer formed of an elastic material, and supports the bottom portion (5a, 5a1, or 5a2) of the reservoir (5). A cover portion (9a, 9a1, or 15) covering a boundary between the outer support portion (4b) and the inner support portion (4a) is provided between the support portion (4) and the intermediate member (10).

The basin cover having evenly-spaced covering elements mounted to shelf angles along the sides of the basin. These shelf angles are retained by anchor bolts to the inside edge of the rim of the basin. Flat tabs are adjustably spaced apart along the shelf angles and respectively overlap unevenly-spaced anchor retention areas of the basin. The flange portion of the shelf angles extend in a same plane as a walkway along the rim of the basin for widening this walkway. The new cover can be installed to basins of different conditions without major custom work.
