Novel flexible coast protection structure and construction method thereof

Abstract

The invention discloses a novel flexible coast protection structure and a construction method of the novel flexible coast protection structure. The structure comprises a mattress tying beam and a wave dissipating platform, wherein the mattress tying beam and the wave dissipating platform are close to the designed water level; the wave dissipating platform is connected with the bottom and the top of a bank slope through a slope and a wave wall respectively; a pebble cushion layer and composite geotextiles are sequentially laid on the lower surface of the slope and the lower surface of the wave dissipating platform. Composite geotextiles and a gravel cushion layer are sequentially laid on the upper surface of the slope and the upper surface of the bottom of the bank slope. A concrete hinged mattress is laid on the gravel cushion layer. The top end of the hinged mattress is connected to the mattress tying beam. The method comprises the steps of prefabrication of concrete ballast block bodies, construction of the mattress tying beam and a bank protection structure above the mattress tying beam, splicing of the concrete hinged mattress, mattress sinking construction and the like. Compared with the existing coast protection technology, the novel flexible coast protection structure has the advantages that the integrity is good, the anti-erosion capability and the coastal erosion deformation adaptability are high, materials are easy to obtain, construction is easy, and maintenance management is convenient; the problem that a traditional rigid seawall bank protector is prone to collapse and damage on the condition of coastal washout deformation can be effectively solved, and a new approach is provided for coast protection.

Description

technical field [0001] The patent of the present invention belongs to coastal protection facilities, specifically refers to seawalls that can better adapt to beach erosion and deformation, and is mainly used in erosive silt and muddy coasts. Background technique [0002] my country's coastline is long, and the problem of coastal erosion is serious, especially the beach erosion caused by strong wind waves and storm surges, which has seriously threatened my country's land resources and the safety of life and property of coastal people. In order to protect the coastline, people have built different types of coastal protection structures in different periods, such as dry block stone revetment, poured block stone revetment, concrete revetment, etc., but the rigid embankment structure cannot adapt to the long-term erosion caused by waves. Deformation of the beach may easily cause the lower part of the seawall revetment to be emptied, and gradually develop into a cavity, and the su...
