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

Embodiment Construction

[0018] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0019] The invention provides a device for suppressing seabed scour of pile foundations of marine buildings, aiming at the problems of poor protection effect and easy occurrence of local scour in the existing seabed scour protection method.

[0020] Such as figure 1 , figure 2 and image 3 As shown, in this device, the reinforced steel pipes 2 are closely arranged around the pile 1 or the foundation on the seabed, and are covered with the critical line 3 of foundation scour failure. Gradually extend to form the envelope 4 at the top of the steel pipe, and pour concrete 5 between the gaps between the steel pipes 2 and the upper cavity. Among them, such as figure 1 As shown, the reinforced steel pipes 2 are closely arranged around the pile 1, and the ...

Abstract

The invention provides a device for suppressing seabed scour of pile foundations of marine buildings, which belongs to the technical field of foundation treatment engineering. The device includes piles, reinforced steel pipes, foundation scour failure critical line, steel pipe top envelope, concrete, cutting head, pipe rammer head and pipe rammer. , the pressing depth of the reinforced steel pipe exceeds the critical line of foundation erosion damage, the top of the reinforced steel pipe gradually extends radially to form an envelope at the top of the steel pipe, and the gap between the reinforced steel pipes and the upper cavity are poured with concrete. The design of the device is reasonable, and has the advantages of high reinforcement strength, convenient construction, shortened construction period, etc., and can effectively restrain seabed scour.

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...
