Single pile jacking and slipping boarding process

Abstract

The invention discloses a jacking and sliding process for loading a single pile onto a ship. The jacking and sliding process includes: a pile body is moved along a transverse moving rail to a longitudinal moving rail, and then the pile body is moved to the apron of a wharf along the longitudinal moving rail; the transport ship is allowed to longitudinally docked to wharf, and the tail of the single pile is allowed to extend 7m out of a fourth sliding and jacking device; after a second sliding and jacking device moves a position 1m away from the apron of the wharf, the fourth sliding and jacking device jacks, the second sliding and jacking device descends, and the fourth sliding and jacking device is pulled to slide the single pile foundation onto the ship; when a first sliding and jackingdevice touches the second sliding and jacking device, a third sliding and jacking device jacks, the first sliding and jacking device descends and moves backwards, the second sliding and jacking devicejacks when the second sliding and jacking device is 4m away from a pile flange, and the third sliding and jacking device descends; a winch on the ship is used to pull the single pile foundation to slide onto the ship, and the winch is stopped after the gravity center of the single pile foundation is 10m away from the third sliding and jacking device; the second sliding and jacking device descendsand the third sliding and jacking device jacks to pull the single pile foundation to a final position on the ship. By the process, the single pile can be loaded onto the ship.

Description

technical field [0001] The invention relates to a single pile boarding process, in particular to a single pile jacking and sliding boarding process. Background technique [0002] In 2018, the world is expected to add 3.9GW of offshore wind power grid-connected capacity, and the mature development of offshore wind power technology in the European market will become the main driving force for the accelerated implementation of heavy industry offshore wind power projects. The report predicts that from 2017 to 2026, the global offshore wind power industry will develop steadily, with a compound average growth rate of 16%. [0003] At present, my country's wind power market is booming. There are 15 wind farms under construction, and 500 wind power monopile foundations need to be fabricated and installed. Each wind power single pile foundation weighs about 700t, and its weight is increasing with the increase of power generation. In the future, the weight of single pile foundation w...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of a single pile foundation, the infrastructure of many domestic manufacturers limits the production, hoisting and delivery of single pile foundations

This will lead to the production speed not reaching the market demand
