Wind power and bridge rock-socketed self-elevating construction platform

Abstract

The invention relates to a wind electricity and bridge rock-socketed self-lifting type construction platform, comprising a self-lifting type construction platform (1); four corners of the self-lifting type construction platform (1) are equipped with four lifting pile legs (1.1); a drilling device (2) is mounted on the deck of the self-lifting type construction platform (1); the drilling device (2) comprises a group of opening-closing type portal, a pressurizing oil cylinder (2.5) is arranged on the portal, the portal is internally and glidingly provided with a pressurizing slide block (2.6), the pressurizing oil cylinder (2.5) applies downwards pressure to the pressurizing slide block (2.6), and a drill stem (2.7) is vertically downwards arranged on the pressurizing slide block (2.6), the bottom part of the drill stem (2.7) is equipped with a drill bit (2.8). The wind electricity and bridge rock-socketed self-lifting type construction platform is high in construction efficiency and good in construction effect.

Description

technical field [0001] The invention relates to a self-elevating construction platform for offshore operations, in particular to a drilling and piling platform for offshore construction, which can be applied to the fields of wind power and bridge pile foundations, and belongs to the technical field of marine engineering. Background technique [0002] At present, wind energy, as a clean and renewable energy, has been paid more and more attention by countries all over the world; its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the available wind energy is 2×10^7MW, The total amount of water energy that can be developed and utilized on the earth is 10 times larger; [0003] In view of the national conditions of my country's vast territory and long coastline, offshore wind energy resources are very rich and have great application prospects; and offshore wind power generation has the advantages of high wind speed, long effective power generation time, ...

AI Technical Summary

Problems solved by technology

[0004] Most of the offshore wind farms that have been built today use a single-pile foundation, that is, a large-diameter steel pipe pile is directly driven into the seabed as the foundation of the wind turbine; the main advantages of the single-pile foundation are simple structure and easy construction. Convenience; to meet the needs of offshore operations, some companies have developed "a buoyant box-type positioning tool for piling offshore wind power foundations" disclosed in 201410186577.6, which adopts floating operation methods; however, with the rapid development of wind turbine manufacturing technology, single machine As the capacity continues to increase, the diameter of the required single pile becomes larger and larger, and the difficulty of seabed surface drilling, pile foundation hoisting and driving also increases; the above-mentioned tooling has been completely unable to adapt to the new operation requirements
