Wind power and bridge rock-socketed construction process

Abstract

The invention relates to a wind power and bridge rock-socketed construction process. The wind power and bridge rock-socketed construction process comprises the steps that 1, a self-lifting type construction platform sails above a construction position; 2, lifting pile legs at the four corners of the self-lifting type construction platform fall to the seabed mud surface to lift the self-lifting type construction platform to the upper portion of the sea level; 3, a steel casing is mounted, specifically, a crane on the self-lifting type construction platform lifts the steel casing, and then under the guiding effect of a pile holding device, the steel casing cylinder is vertically downward struck into the seabed mud surface through a vibration hammer; 4, the self-lifting type construction platform is lifted, so that the top of the steel casing is flush with the surface of a construction deck of the self-lifting type construction platform, and accordingly construction space is made; 5, drilling is conducted, and 6, a steel pile is mounted. According to the wind power and bridge rock-socketed construction process, the construction efficiency is high and the construction effect is good.

Description

technical field [0001] The invention relates to a construction process for offshore operations, in particular to a drilling and piling process 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, no land occupatio...

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 single piles required is increasing, and the difficulty of drilling seabed mud surface, hoisting and driving pile foundations is also increasing; the above-mentioned tooling is completely unable to adapt to the new operation requirements
