Problems solved by technology

Traditional protective measures such as riprap and sandbags take a long time to construct at sea, and it is not easy to ensure the uniformity of the throwing construction in the protection area. Among them, riprap construction is also easy to cause damage to the infrastructure; sandbags are easy to be damaged during construction , and it is easy to cause the erosion protection to fail due to the liquefaction of the sand in the bag

Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, this embodiment is an application example of a large-diameter single pile foundation, including a large-diameter single pile 1 and a flexible erosion protection structure of the large-diameter single pile 1 .

[0021] The flexible scour protection structure includes a flexible scour protection surface 4 . A plurality of protection units 2 are connected by connecting cables 3 to form a flexible scour protection surface 4 .

[0022] The protective unit 2 is made of prefabricated concrete blocks or waste tires or other materials. The protective monomer can have multiple implementations, such as Figure 3-1 , 3-2 , 3-3, the protection unit 2a can have a groove 21 on the outside and after a plurality of protection units 2a are connected by the connecting cable 3, the groove forms a cavity 5 through the flexible scouring protection surface. The side wall of the cavity is also concave 51 on the groove wall, preferably, the entire gro...

Abstract

The invention provides a flexible flushing protective structure for marine engineering infrastructure. The flexible flushing protective structure comprises a plurality of protective units and connecting cables, wherein the protective units are connected by the connecting cables to form a flexible flushing protective surface laid on the seabed surface; and the flexible flushing protective surface is provided with a cavity formed in an up-and-down penetrating mode. The flexible flushing protective structure can intercept passing sediment driven by the ocean current and the passing sediment is stabilized around the protected structure, so that a new flushing balance state is formed around the protected structure, the flushing protection is formed, the stability of the structure is protected,and the flushing protective effect is good; moreover, the shapes of the protective units can be maintained for a long time and the service life of the entire flexible flushing protective structure isensured; and the protective units are prefabricated on land, and the efficiency of offshore construction is improved.

Description

technical field [0001] The invention relates to a flexible erosion protection structure of an ocean engineering basic structure. Suitable for scour protection of marine engineering infrastructure. Background technique [0002] Fixed offshore wind turbine foundations, offshore wind measuring towers and other marine engineering infrastructure structures, under the action of ocean currents, will form scour pits around the foundation structures at the seabed surface. Designing and implementing effective scour protection measures is essential for ensuring the foundation structure and The stability of the overall structure plays an important role. Traditional protective measures such as riprap and sandbags take a long time to construct at sea, and it is not easy to ensure the uniformity of the throwing construction in the protection area. Among them, riprap construction is also easy to cause damage to the infrastructure; sandbags are easy to be damaged during construction , and ...
