The beneficial effects of the utility model are that the proof strength is good, acid and alkali-resistance, ageing resistance.
Description
Technical Field
The utility model belongs to the technical field of the bank line protection, a bank line sand dune protective structure is related to.
Background
Coastal erosion is a ubiquitous disaster in the world marine countries, and coastal restoration is also one of the research difficulties and hot spots at present. The coastal wharf construction and large-scale aquaculture change offshore hydrodynamic conditions, so that the shore line erosion is aggravated, storm waves propagate from deep water through a wave transition region, the waves start to break at a breaking point, the broken storm waves have great wave energy, and a violent and highly turbulent water body is generated to suspend sediment in the wave breaking region and generate a bottom surface flow layer with high-concentration sediment; broken waves with high wave energy climb on the beach, slap on the bottom of the beach and sand dunes/artificial protective walls, the periodic reciprocating water flow of the up-flow zone can convey a large amount of sand dunes and sand beach sand to a wave breaking area, the bottom high-concentration suspended sand is conveyed out of the broken area under the conveying of bottom offshore flow, and the physical process is repeated by the periodic waves to cause beach erosion. Coastal restoration work requires deployment. Based on field data acquisition, a shoreline protection mechanism and an engineering construction method are researched, a physical evolution process of a beach section under the action of storm surge and heavy wave is researched, a shoreline specific change erosion mechanism in the storm surge process is researched, a bottom bed dynamic response evolution process and a corresponding sediment starting-transporting-depositing evaluation standard are researched, an important effect of wave climbing in the storm surge process on beach-dune erosion is further researched, a shoreline specific change erosion mechanism in the storm surge process is researched, a bottom bed dynamic response evolution process and a corresponding sediment starting-transporting-depositing evaluation standard are researched, and an important effect of wave climbing in the storm surge process on beach-dune erosion is further researched.
SUMMERY OF THE UTILITY MODEL
