Description
Technical Field
The utility model relates to an installation of marine wind power basis, wind energy engineering, new forms of energy, in particular to broken dumping of sharp subregion machinery sinks device based on marine wind power square tubular type basis realizes the installation of the compound cartridge type basis high efficiency of thick wall concrete.
Background
With the increasing prominence of global energy, climate, environment and other problems, renewable energy is generally concerned by various countries. Compared with the traditional fossil fuel, the wind energy is clean in use and low in cost, and has the advantages of wide development range, safety, inexhaustible energy and the like. Compared with onshore wind power, offshore wind power has the advantages of high wind speed, low turbulence, no land occupation and the like. At present, the offshore wind power foundation in China mostly adopts a pile foundation or a composite pile foundation, the design is simple, the installation process is mature, but the horizontal deformation caused by transverse loads (wind, wave and flow) is large. The appearance of wide shallow formula section of thick bamboo type basis provides new direction for the design of marine fan basis, and great transverse load that marine fan received can effectively be resisted to this basis, and its simple structure, cost are lower, the construction is convenient quick.
In recent years, with the successful application of the offshore composite cylindrical fan foundation and the one-step installation technology of the fan, the construction cost of the offshore wind power foundation is greatly reduced, and the method is suitable for the areas with proper water depth and geological conditions in part of China and has good engineering application prospect. At present, a designed and installed composite cylindrical foundation consists of a concrete transition section, a circular steel cylinder and a steel bin distribution plate. In order to further reduce the cost of the cylinder foundation, a concrete cylinder can be used for replacing a steel cylinder on the premise of ensuring the design strength requirement. Since concrete is less rigid than steel, thicker concrete walls (about 0.4m) are required to meet the corresponding design requirements, which also puts higher demands on the later submerged installation. The thickening of section of thick bamboo wall will certainly increase the end resistance of sinking in-process, can't guarantee quick effectual sinking operation, weakens the superiority of one-step mounting technique to a certain extent. The existing steel-concrete composite cylinder type foundation bottom soil breaking device combines slotting soil breaking and high-pressure injection soil breaking, and is combined with partition soil breaking, so that the problem of unbalanced levelness in settlement caused by the difference of geological structures of different parts of the seabed is effectively solved, but the mechanical soil breaking efficiency is restricted by an annular track by partitioning on a cylinder arc-shaped thick wall, and is not as high as the soil breaking efficiency of a side wall linear track of a square cylinder type foundation. Meanwhile, the seabed soil is mostly silt clay, and broken clay is difficult to take away by hydraulic flushing, so that the sinking efficiency is seriously influenced; and the excessive flushing pressure can enlarge the area range of the disturbed soil body, which is not beneficial to the stability of the cylinder type foundation operation period.
Therefore, the utility model provides a broken dumping of sharp subregion machinery sinks device based on marine wind power square tube type basis, the device utilize mechanical subregion to break ground, arrange soil, when having guaranteed the control of levelness, make the fan basis sink to target in place fast effectively safely.
