The upper carrier part, ballast and underwater parts consist of separate blocks rigidly interconnected by permanent or temporary bond. A separate bearing block is a hollow box with an internal floor joists. The housing has an internal voids of a given configuration, designed to ease the weight of the structure without compromising strength characteristics. Ballast blocks are also made with voids and equipped for filling-emptying.The required number of segments equipped with an anchor mechanism for anchoring to the ground.On the accompanying drawings shows: Fig. 1 - floating platform, top view; Fig. 2 shows a section a - a of Fig. 1; Fig. 3 - section b-B of Fig. 1; Fig. 4 - slice of the chassis bearing block of Fig. 5 - General view of a single segment of the design of coastal defences; Fig. 6 - section a-a segment of the coastal protection, equipped with an anchor mechanism; Fig. 7 is a schematic arrangement of cable ties over the entire area of the platform (top view).On the accompanying drawings, the following notation: 1 - blocks bearing part of the platform; 2 - blocks of the ballast of the platform; 3 - segments of the construction of coastal protection; 4 - blocks underwater part of the platform; 5 - lightweight blocks bearing part of the platform; 6, 7, 8, 9, 10 - blocks of segment construction of coastal protection; 11 - winch; 12 - rope or chain; 13 - block transfer; 14 - "speed" cable in the form of reinforced concrete pipe; 15 - the mechanism of a tension of a rope.Floating platform consists of separate necesito interconnected temporary or permanent connection. Each block consists of a hollow box with an internal floor joists and can be made of monolithic reinforced concrete with an outer layer active waterproofing of PVC skin or other insulating material and a layer of concrete with silicone additives for passive waterproofing. The entire body of the block (Fig. 4) has an inner emptiness that can ease the weight of the structure without compromising strength characteristics. The number of blocks in the platform depends on the useful area of the bearing part of the platform. Mounting blocks produce one of the known methods. When designing the platform can be modeled landscape, leaving internal waters, Bay port, etc. For increasing the surface areas you can use lighter-weight bearing blocks 5 (Fig. 3), which are one of the top overlapping (possibly below the top edge, to fill the resulting space with soil).Ballast blocks 2 are used for installation and further operation of the platform. Ballast blocks can be identical in size, and carrying, have internal waterproofing, facilitated by replacing the internal floors and bulkheads spacer on the design of coastal defences (Fig. 2, 3). This design is an "artificial beach", consisting of individual segments (Fig. 5, 6), which, in turn, are composed of building blocks 6, 7, 8, 9, 10 ( for more convenient transportation to the place of operation) that make up each segment of the inner reservoir, allowing you to use the kinetic energy of the water against rocking platform. Each individual unit of the coastal protection represents a ballast system, equipped with a permanent filling-emptying, or a special platform with holes for mounting the pumping equipment at the time of installation design. The required number of segments equipped with an anchor mechanism for anchoring to the ground (Fig. 6), anchor mechanisms can be used for damping oscillations of the platform.When using the platform for industrial purposes associated with the development of seabed mining, construction engineering objects, and so on), it is advisable to use blocks underwater platform 4 (Fig. 2), also identical in size to the bearing blocks. The lower platform can be equipped for works under the water.In addition to the existing kreplenie to increase the rigidity of the structure. In Fig. 7 position 14 labeled "speed" cable, which can be used in thick-walled concrete pipe, penetrating the block through. The mechanism of a tension of the cable 10 may be used any of known.Composite blocks of the platform are made on the coastal shipyards and delivered to the site by sea. It is possible to manufacture the blocks directly on site, which requires more sophisticated equipment floating wharves and some different technology, although this method of manufacture has its own, quite large advantages, such as: increasing the strength of the structure, reducing the amount of consumables and others. The proposed dimensions of the composite bearing blocks - 20x30x16 meters allow you to place inside a block of up to five floors. I.e., the effective area of this platform, unlike similar increases five times. When designing an object, it is possible to model the Association of the blocks, leaving the blocked technical transitions, dismantled after the docking blocks at the place of operation and sealing of the seams. The estimated weight of an unloaded block that allows you to stay afloat at least one third block, the app is a mix of each block of more than 3000 tons. Depending on the destination platform, the block size can vary within fairly wide limits.The literature used in the preparation of the description:
