Abstract
The invention provides a modular device and a method for repairing a dam breach, which are mainly characterized in that a precast concrete box with a shape comprising a rectangular parallelepiped and a hexagonal cylinder can be assembled together to form a seawall, a dam, a breakwater and other waterfront structures. The present invention also discloses a new method of water transport and installation of an array comprising modular vessels having bow and stern sections which may be directly connected together or mounted to an intermediate section containing such a water tank assembly, other structural elements or other vessels, such as floating dry docks and the like.
Description
Technical Field
The present invention relates to the manufacture, transport, use and installation of various prefabricated box-like assemblies to form land, shorelines and floating structures. The present invention can be used for a variety of purposes including pre-hurricane and flood incident mitigation and post-incident recovery, defense and homeland security facility construction.
Background
Usually, large riprap revetment, spur dike or breakwater will be used for repairing and protecting the dam. However, these methods require large quantities of construction materials to be transported to the site. The rocks in the construction material are difficult to handle, do not allow for interconnection or floating on the water surface, and are not able to be positioned during construction. Furthermore, rock-like construction materials are not suitable for intermodal or use in modular systems.
Disclosure of Invention
It is an object of the present invention to provide easily transportable structural components that can be used to control shoreline erosion. Another object is that such components should be compatible in size, shape and proportions with existing truck, rail car and marine modes of transport (i.e. intermodal) and be suitable for use with existing material handling equipment. Another object is that the assembly can be transported in sections for installation by moving it to the building's crowded seashore area by land, water or heavy helicopters, airships, etc.
Another object of the present invention is to provide corresponding structural components, such as partially closed containers that are light in weight but can be filled with available liquid or solid materials at the installation site, which significantly increase their mass at low cost. It is another object of the present invention to provide structural components that, when installed as part of a structure, can be filled with solids, gases or liquids to increase their mass, while serving as a sealed storage container for such materials for later use.
It is another object of the present invention to provide a structural member having maximum mass when filled with ballast material and installed in a structure. It is desirable to maximize the mass of such members so that the structure can resist the tremendous forces generated by storms, ocean currents, floods, debris flows, earthquakes and other natural disasters. Such mass maximised structures have similar applications in operational engineering, for example to resist military attacks, gunfire attacks etc.
It is another object of the present invention to provide an intermodal transport device for precast concrete tanks that can be used as a fixed or floating building component for various civil, marine, commercial or military construction projects. Such components may be connected together to form embankments, fixed or floating bridges, dams, drilling rigs, floating or fixed airport runways, helidecks, temporary or permanent shipping ports, temporary military or naval facilities such as ports, maintenance, supply or airport facilities, "container ships", repositionable modular seaside structures such as houses, and many other applications.
It is another object of the present invention to provide a method of installing precast concrete tanks at an underwater location by transporting the precast concrete tanks to a floating vessel or floating them to an approximate location and sinking them into a final installation location or assembling them into a floating structure. A related object is to provide a vessel suitable for transporting such tanks. Another related object is to provide precast concrete members that can be interconnected to form part of the hull structure of such modular vessels.
According to the present invention, there is provided a precast concrete box, preferably in the form of a rectangular parallelepiped, transportable through the water surface and assembled to form a coastal line structure. As an alternative to such precast concrete tanks, similar tanks may be made of a material selected from the group consisting of metal, wood, plastic and polymer composites. The box of such material may be coated with concrete at least on its outer surface to form a device having the characteristics of a precast concrete box. The concrete or plastic tank may be coated with various suitable materials to provide weathering, liquid and corrosion resistance.
Another aspect of the invention relates to an assembly for temporary or permanent shorelines or shallow water structures using the transport of metal or other materials or as shipping containers, which employs precast concrete tanks having a rectangular parallelepiped form. Such metal or other material containers may be coated with a layer of concrete using conventional spray techniques (such as "shotcrete" or shotcrete techniques) on site or prior to transport to the job site. Alternatively, the rust inhibiting synthetic coating, such as a three component mixture containing zinc, a coal tar derivative, a polyurea coating, and an epoxy resin, can be applied by conventional methods such as spraying, brushing, dipping, and the like. These rectangular containers made of metal or other materials may be fitted with partitions, watertight covers or closures, valves and fittings for the inflow and discharge of water to float the container.
In addition to the shoreline structure previously disclosed, the prefabricated rectangular boxes of the present invention, whether prefabricated concrete or a standard metal shipping container with some modifications, can be used for the construction and repair of dikes (dikes or berms bordering a river bank to prevent overflow at high water levels), dikes, dams, and the like.
Drawings

FIG. 2 is a side view of the precast concrete box of the present invention;
fig. 3 is an end view of the precast concrete box of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Fig. 1, 2 and 3 are plan, side and end views of the precast concrete box of the present invention, which can be used for a shoreline, underwater, and intertidal zone. The box (90) takes the form of a simple hollow box in the form of a rectangular parallelepiped, having sides, ends, a bottom and an open top, optionally covered with a close-fitting top (92), held in place by gravity or optional mechanical fasteners (not shown here). The top (92) is omitted from fig. 1. Holes (94) are provided in the lower corners of the sides and ends for connection of cables or rods (not shown here). Vertical holes (96) are provided in each corner of the top of the case to help secure the top (92) when in use, or for mechanical attachment means when the cases are stacked or secured to the bottom. A lower sill (98) on the inner bottom divides the box into two halves for joining the overlapping boxes together, and a hole (99) extends laterally through the sill from one side to accommodate a cable or pole or like connection means as well as a carrying device. The tanks shown here are fluid-tight, and they are open to water immersed therein. The cases may be positioned adjacent to each other (side-by-side or end-to-end) and fastened together using holes (94), (96), and (99) and various mechanical fasteners. When interconnected side-by-side, the cases are preferably positioned in an overlapping manner (the ends of two cases being located near the center of the third case) to form a stronger structure.
