Concrete soft mattress anti-scouring device with energy dissipation net and construction method thereof

Abstract

The invention discloses a concrete soft mattress anti-scouring device with an energy dissipation net, which comprises a soft mattress laid around a pile foundation, a main body of the soft mattress is formed by connecting rectangular concrete blocks which are transversely arranged in rows and vertically arranged in columns, the periphery of the soft mattress is formed by connecting hemispherical concrete blocks, every two adjacent rectangular concrete block bodies, every two adjacent hemispherical concrete block bodies and each hemispherical concrete block body and the adjacent rectangular concrete block body are connected through connecting ropes, and the connecting ropes are arranged on the peripheries of the rectangular concrete block bodies and the peripheries of the hemispherical concrete block bodies. The energy dissipation net extending in the length direction of the rectangular concrete block is fixedly connected to the top of the rectangular concrete block. A gap between the soft mattress and the pile foundation is filled with a sand bag in a pressing mode. The invention further discloses a construction method of the anti-scouring device. The device can effectively weaken or restrain washing of water flow and protect the offshore wind power foundation, and the protection effect is remarkable.

Description

technical field [0001] The invention relates to an anti-scouring device and a construction method thereof, in particular to a concrete soft row anti-scouring device with an energy dissipation net and a construction method thereof. Background technique [0002] Wind energy is a renewable and clean energy. Offshore wind power has a high utilization rate of wind energy and has little impact on human production and life. It is suitable for the construction and development of coastal cities. Coastal areas can completely realize "electricity from the side" by utilizing offshore resources, and embark on a green and sustainable development path, and offshore wind power motors are the core equipment. Due to the complex offshore environment, the pile foundation is subjected to loads such as wind, waves, and currents, and scour pits are often formed around the pile foundation, which will even weaken the horizontal bearing capacity of the pile foundation, increase the chance of pile fou...

Problems solved by technology

There are three commonly used technologies at present, one is riprap protection, which is characterized by convenient construction and short construction period, but the overall stability of the anti-scouring protective layer formed after completion is poor; the other is sand quilt protection, which is characterized by large-scale construction And the cost is low, but the construction accuracy is difficult to grasp and its durability needs to be tested; the third is the silt solidification technology, which uses a solidifying agent to change the properties of the silt to achieve the solidification effect, but it may harm benthic marine organisms and damage the marine environment
