Abstract

The invention discloses a hard-shell benthos anti-scouring structure of a marine foundation and a construction method. The benthos anti-scouring structure comprises piles and stones to which hard-shell benthos is attached to grow and hard-shell benthos. The construction method specifically comprises the steps of arranging the multiple cement piles and stones to which the hard-shell benthos can beattached to grow around the marine foundation, and scattering young hard-shell benthos to an area formed by the marine foundation, the piles and the stones; and after the hard-shell benthos is attached to the piles and the stones to grow, scattering the young hard-shell benthos for multiple times to supplement gaps among the benthos until a formed benthos anti-scouring hard shell layer of the marine-foundation-benthos-soil-body completely covers an original soil layer. The anti-scouring structure is simple in form, convenient to construct, cost-saving, high in compatibility among the benthos and the marine environment, and capable of solving the problems that a common throwing and feeding protective layer is prone to failure and the marine engineering is prone to causing marine ecologicaldamage to the marine environment while effectively preventing scouring.

Description

technical field [0001] The invention belongs to the field of ocean engineering, and in particular relates to an anti-scouring structure and construction method of a hard shell benthic organism of an ocean engineering foundation. Background technique [0002] When the offshore foundation is in service in the ocean, under the action of hydrodynamic forces such as waves and currents, the sediment around the offshore foundation often migrates, and then scour pits are formed. The formation of scour pits reduces the contact depth between the marine foundation and the surrounding seabed, and reduces the bearing capacity and stability of the marine foundation. In severe cases, it will cause the marine foundation to capsize, causing major economic losses. [0003] Most of the existing erosion protection around the foundation is passive protection. Passive protection refers to the protection means to improve the anti-scouring ability by starting from the seabed and the foundation and ...
