A submersible control dam made of basalt fiber composite material

Abstract

The invention discloses a submersible type sand blocking dam made from a basalt fiber composite material. The submersible type sand blocking dam made from the basalt fiber composite material comprises two sand blocking dam sand fixing frameworks arranged in a crossed manner, sand fixing wing net frameworks arranged on the side faces of the sand blocking dam sand fixing frameworks, longitudinal sand blocking plates which are downwards arranged on the long edges of the bottom faces of the sand blocking dam sand fixing frameworks, and transverse sand blocking plates which are downwards arranged on the short edges of the bottom faces of the sand blocking dam sand fixing frameworks; sand blocking dam fixing stand columns are evenly arranged at the bottoms of the sand blocking dam sand fixing frameworks, and wing net fixing columns are evenly arranged at the bottoms of the sand fixing wing net frameworks; each sand blocking dam sand fixing framework comprises basalt ribs, a basalt supporting grid and a sand fixing fine net; and each sand fixing wing net framework comprises basalt ribs, a basalt supporting grid and a sand fixing fine net. The sand blocking dam sand fixing frameworks of the submersible type sand blocking dam are arranged in a crossed structure, and corrosion of front side surging, transverse ocean current and irregular wave flow to the seacoast can be prevented at the same time. The whole sand fixing wing net frameworks on the four sides of the sand blocking dam sand fixing frameworks can prevent that returned waves blow away silt at the bottom of the periphery of the sand blocking dam, and stability of a dam body foundation and stability of the peripheral seacoast are protected.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a submerged sand dam, in particular to a submersible sand dam made of basalt fiber composite material for preventing coastal erosion and controlling sea sand flow. Background technique [0002] Coastal erosion and coastal sand loss or siltation are marine disasters that have seriously threatened social production activities and people's life and property safety in coastal areas of my country for a long time. The interference and destruction of coastal sand mining, coastal engineering construction, mariculture activities, and coastal erosion disasters are becoming more and more serious, and are currently regarded as one of the serious marine disasters. [0003] At present, artificial construction of reinforced concrete, mortar block stone tidal dike, breakwater, bag cement slope protection, wave retaining wall and other methods are mainly used to prevent coastal erosion, but all o...

AI Technical Summary

Problems solved by technology

[0003] At present, artificial construction of reinforced concrete, mortar block stone tidal dike, breakwater, bag cement slope protection, wave retaining wall and other methods are mainly used to prevent coastal erosion, but all of them have high project cost, long construction period, and may damage the original ecological environment and Coastal structure, change the original ocean current law, change the natural flow direction of sea sand and form new geological disasters, etc.

At the same time, the ability of anti-wind and wave of sediment breakwater is weak

Although some coastal scenic spots use artificial sand replenishment methods, the amount of sand replenishment is large, and the cost of sand mining and transportation is high, and repeated replenishment is required, which can only play a role in palliative and temporary relief.
