A jack for lifting segments of a structure includes a pair of masts, a mast base, a mast cap, a hydraulic ram, a bottom bracket and a shuttle. The masts are identical and upright with a plurality of evenly spaced holes. The mast base supports the mast and the mast cap receives the upper ends of the masts and maintains the masts in a parallel, relationship. The hydraulic ram moves between a retracted position and an extended position with a stroke distance which is significantly less than the mast height. The bottom bracket is removably pinned to the masts and receives and supports the lower end of the hydraulic ram. The shuttle receives the upper end of the hydraulic ram. The bottom bracket and shuttle, when not pinned to the masts, can slide vertically up the masts. The shuttle includes features for connecting to a segment of a structure.

A flexible and waterproof containment tube sits within a basin and prevents objects from entering the basin. When placed inside the basin, the containment tube is filled with a filling fluid. The dimensions of the containment tube are similar to that of the basin such that the containment tube fits within and fills substantially all of the basin. The outward hoop stress of the side portion against the walls of the basin evenly distribute pressure and protect the basin from damage, such as debris, rain or flood, water, or other objects.

A floating roof assembly includes longitudinal girders, and floating members arranged in rows that alternate with the longitudinal girders. Upper and lower press bars are disposed across and fixed to the longitudinal girders. Each of the upper and lower press bars has fastening holes each of which has a first hole portion and a second hole portion. Fastening members connect the upper and lower press bars to the longitudinal girders through the fastening holes. When the fastening members reach the second hole portions of the upper and lower press bars, the longitudinal girders can increase a clamping force thereof to clamp the floating members.

The invention relates to a removable deflector for protecting the feet of a structure, which corrode following infiltration of water under the bottom plates and which weakens these areas. The invention concerns a removable device enabling the positioning of protection for the feet of storage tanks without a shut-down of production. The device according to the invention is a deflector element and a deflector assembly consisting of a plurality of deflector elements, capable of being positioned one after the other in order to surround the feet of the wall of the structure. Each deflector element comprises at least one downward-sloping protective plate (1), at least one flexible sealing gasket attached along the upper edge of this plate (1), and: at least one retaining arm (5) for same, wherein one of its ends is fixed to the so-called upper edge of said plate (1) and the other so-called distal end is capable of being rigidly and reversibly attached to an element of said structure and to be detached therefrom, this arm allowing the adjustment of the pressing of the sealing gasket against the wall (14) of the tank, and at least one support (6) arranged towards its lower edge and separable into at least two parts suitable for making the deflector removable, of which the upper one is attached underneath the plate (1) and the other, lower one, is attached to the support slab (23) of the structure wall (14).

A landscaping barrier comprises a first longitudinal member, a second longitudinal member and a third longitudinal member. The second longitudinal member may be attached to and extend substantially perpendicular from one edge of the first longitudinal member while the third longitudinal member may be attached to and extend substantially perpendicular from the opposite edge of the first longitudinal member and in the opposite direction of the second longitudinal member.

A fluid storage tank includes a plurality of end panels defining a plurality of curved wall sections and a plurality of side panels extending between and connecting the plurality of curved wall sections. The plurality of end panels and plurality of side panels define a perimeter wall. The fluid storage tank further includes a plurality of cable arms, each of the cable arms connected to a flange of at least one of the plurality of end panels or side panels, and at least one upper tension member having a first end connected to one of the plurality of cable arms and a second end connected to another of the plurality of cable arms.
