Device for inhibiting seabed scouring of marine structure pile foundation

Abstract

The invention provides a device for inhibiting seabed scouring of a marine structure pile foundation, and belongs to the technical field of foundation treatment engineering. The device comprises a pile, reinforced steel pipes, foundation scouring damage critical lines, steel pipe top envelope lines, concrete, a cutting head, a pipe compaction head and a pipe compaction hammer; the reinforced steel pipes are tightly arranged around the pile foundation at the seabed; the foundation scouring damage critical lines are fully distributed; the pressing depths of the reinforced steel pipes exceed the foundation scouring damage critical lines; the tops of the reinforced steel pipes gradually extend in the radial direction to form the steel pipe top envelope lines; and the concrete is poured in gaps of the reinforced steel pipes and upper cavities. The device is reasonable in design, has such advantages as high reinforcing strength, convenience to construct and short construction period, and can effectively inhibit the seabed scouring.

Description

technical field [0001] The invention relates to the technical field of foundation treatment engineering, in particular to a device for suppressing seabed scour of pile foundations of marine buildings. Background technique [0002] Renewable energy is becoming more and more important to national and global energy policies, and the amount of investment caused by the use of renewable energy is gradually increasing. Offshore renewable energy devices include tidal energy devices, wave energy devices and offshore wind turbines. Wind turbines (wind generators or Other wind energy capture devices) are usually multi-bladed devices mounted on towers secured in place with single or triple piles. Offshore wind turbines installed in the monopile type are susceptible to seabed scour (eg caused by tidal changes, heavy rains), which will cause the seabed around the base of the monopile wind turbine to move. [0003] According to the survey, around the wind turbine single pile without scour...

AI Technical Summary

Problems solved by technology

Traditional offshore wind turbine erosion protection usually adopts armor protection, such as laying a layer of rock around the bottom of the pile, usually the diameter of the rock is about 50-100cm, and the gaps between smaller rocks are still large, and the anti-scour effect is not very good; moreover, The traditional method will produce localized scour and cause the scour limit to expand
