摘要:
The formation of an artificial island in a body of water is effected by injecting a gellable, cross-linkable fluid, such as a blend of a water-soluble polymer and a cross-linking agent therefore, from a vessel below the surface of the water and moving the vessel to form a strip of a gelled mass. The gellable fluid is injected such that it extends from the floor of the body of water to the surface thereof. A dense solid material may be incorporated in the gellable fluid. An exposed section may be formed on the strip by either injecting a gas along with the gellable fluid in the upper region thereof, or pouring additional gellable fluid over the formed strip prior to complete setting of the surface of the gellable mass. The strip may be formed to enclose a section of water and the water in said enclosed section may be displaced with solid load-bearing material, or ice may be built up within the enclosed section to serve as a load supportive structure.

A concrete float having a buoyant foam core surrounded by a concrete shell. The deck of the shell has integrally formed therewith a plurality of transverse ribs and longitudinal ribs which strengthen the deck. Consequently, the necessary strength for the deck can be achieved by utilizing a substantially reduced quantity of concrete. A tubular conduit extends beneath at least some of the transverse ribs. The conduits are provided in order to receive tie rods having their ends projecting from the sides of the float and through elongated wales which serve to secure the floats to each other. The concrete is preferably reinforced with conventional concrete reinforcing bars. The float is formed by placing a rectangular block of foam in a rectangular form after a layer of concrete has been poured in the form with the foam core being positioned apart from the sides of the form. Transverse and longitudinal grooves are formed in the upper surface of the core, and tubular conduits are placed in at least some of the transverse grooves. Finally, sufficient concrete is poured into the form to fill the sides and cover the upper surface of the foam thereby filling the space between the core and foam. The concrete also fills the grooves in the foam thereby creating the transverse and longitudinal ribs and securing the tubular conduits in position within the transverse grooves.
摘要:
A method of forming an underwater structure which includes fabricating an assembly consisting of an upper deck section, a lower gravity section and an impervious member secured in water-tight fashion to the lower peripheries of the deck and gravity sections. The assembly is floated with the membrane in a folded condition to the site and lowered so that the gravity section rests on the sea or river bed. The space between the sections and the membrane is filled with water and a non-settable particulate material to form a body of such material. The particulate body is drained to enable the external water pressure to exert a confining pressure on the body to render it coherent.

Means for repairing or forming structural bodies of self-hardening fluid cement mortar, in a subaqueous or other situs, utilizing a body-forming cavity including body-shaping walls of porous fabric in combination with openwork matrix means fixedly positioned at the situs. The matrix means is received within the body-shaping walls of porous fabric and connected thereto by tension-restraining tie-elements of predetermined length for controlling limited oppositely outward distension of the opposing walls away from the matrix as determined by the length of the tie-elements, upon reception of fluid mortar or like cementitious material within the body-shaping walls to expand the walls thereof to such given shape and size of the body formed by the cementitious material.

An earthworks is constructed by consolidating solids and/or slurries and using the consolidated material for constructing the earthworks. A quantity of less than 150 grams of hydraulic cement and a quantity of soluble alkali metal silicate containing less than 11 grams of SiO.sub.2 are mixed with each liter of the solids and/or slurry to produce a water insoluble solidified material. The material thus produced is used for the construction of the earthworks. The material can be worked in with other solids, the material will not leach chemicals and the material does not break down into colloidal size particles that would remain suspended in water.
摘要:
Method for repairing or forming structural bodies of selfhardening fluid cement mortar, in a sub-aqueous or other situs, utilizing body-forming cavity including body-shaping walls of porous fabric in combination with openwork matrix means. Fluid mortar or like cementitious material pumped into cavity to fill same and expand fabric walls against tensional restraint of fixedly maintained matrix means. Pressure of fluid material continued against restraint of matrix means until small proportions of fluid material oozes into the porous fabric, and indicates attainment of lowered water-cement ratio in formed body, and then fluid material is allowed to set and harden in said given formed shape. Some, if not all, forms of the invention are particularly useful for under-water installations, such as breakwaters because forming matrices thereof are capable of withstanding rough seas or storm waves without damage during the construction processes, and because the fluid cement mortar pumping operations are possible in minimum of time when rough water conditions subside.

A submersible data center (180, 180a, 180b) configured in a water-tight capsule for deployment in a body of water. The data center capsules (180, 180a, 180b) are mounted on a submersible platform (110) of an elevator apparatus (100, 100a), which is equipped with a support leg (130a) or support legs (130) and winches (132) are located near a top of the support leg or each of the support legs. The data center capsules (180, 180a, 180b) can be submerged underwater for operation or be winched up above the water for retrieval/maintenance. A first-time deployment of the support leg(s) (130, 130a) is provided by leg-lowering winches (112) located on the submersible platform (110). Heat exchangers (190) or chillers (190a) are used, or a centralized chiller (190b) is used, to dissipate heat energy from inside the data center capsules (180, 180a, 180b) to the surrounding water. Accompanying methods of operations are also described.
