Wind power and bridge rock-socketed construction system

Abstract

The invention relates to a wind power and bridge rock-socketed construction system. The wind power and bridge rock-socketed construction system comprises a drilling device (102) installed on a self-elevating operation platform (101). The drilling device (102) comprises a set of portal of an opening-closing type structure. The portal comprises two overturning pieces (1) symmetrically arranged. One end of the bottom of each overturning piece (1) is hinged to a deck of the self-elevating operation platform (101). Upper connecting plates (2) are transversely connected to the tops of the two overturning pieces (1). An overturning oil cylinder (3) is arranged beside each overturning piece (1). A sliding groove (4) is vertically formed in the inner side wall of each overturning piece (1). A pressurization oil cylinder (5) is installed at the top of each overturning piece (1), and a piston rod of each pressurization oil cylinder (5) is arranged in the corresponding sliding groove (4) in an inserted mode. Pressurization sliding blocks (6) are clamped in the sliding grooves (4) of the two overturning pieces (1) arranged left and right. The wind power and bridge rock-socketed construction system is high in construction efficiency and good in construction effect.

Description

technical field [0001] The invention relates to an offshore self-elevating operation platform, in particular to a platform for performing drilling operations in the drilling and piling process of marine 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 eff...

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
