A kind of sand-fixing and wave-dispelling type dredging island and reef slope protection made of basalt fiber

Abstract

The invention discloses a sand-fixing and wave-breaking hydraulic-filled island-reef revetment made of a basalt fiber. The revetment comprises fixing vertical columns, a solidification layer, porous wave-breaking pipes, a basalt tied rebar grid layer and crisscross water-blocking rods, wherein the porous wave-breaking pipes are vertical hollow pipes; symmetrical wave-breaking holes are formed in the pipe walls of the vertical hollow pipes; and the fixing vertical columns, the solidification layer, the porous wave-breaking pipes and the crisscross water-blocking rods are all formed by pouring cement onto basalt fiber tied rebars and then coating the cement-poured basalt fiber tied rebars with basalt impermeable geotextile. The revetment disclosed by the invention is environmentally friendly, modular in production, light in weight, resistant to corrosion, short in construction period, convenient to construct and strong in anti-wave capability; the revetment is made of a basalt fiber composite, and the basalt fiber is not only relatively high in mechanical property but also strong in corrosion resistance, relatively high in cost performance, long in service life and free of secondary pollution; and therefore, not only is the surrounding ecological environment protected from damage, but also the apposition growth of oysters, corals and other sea creatures is facilitated.

Description

technical field [0001] The invention relates to the field of ocean engineering, in particular to a slope protection, in particular to a sand-fixing and wave-dispelling type dredging island reef slope protection made of basalt fiber composite material to prevent the slope protection from collapsing after being hollowed out by waves and sea sand. Background technique [0002] Coastal erosion is a marine disaster that has seriously threatened the social production activities and the safety of people's life and property in the coastal and island surrounding areas of our country for a long time. With global warming, sea level rise, storm surges, reduction of sediment entering the sea, and the interference and destruction of human coastal sand mining, coastal engineering construction, and mariculture activities, coastal erosion disasters are becoming more and more serious. one of the disasters.

Problems solved by technology

[0003] Reclaimed islands and reefs are the main form of construction of artificial islands and reefs in coral reefs and sandbar sea areas. They have the advantages of convenient local materials, short construction period, low construction cost, and adaptability to large-scale sand pumping and reclamation operations; all reclaimed islands and reefs are made of coral It is formed by accumulation of sand and coral debris, but at the same time, it is difficult to solidify on the seaward slope and the lagoon slope, and it is easy to be eroded and washed away by waves. Safety on islands and reefs

[0004] At present, the main ways to prevent coastal erosion are: artificial construction of reinforced concrete, mortar block stone tidal embankment, sediment breakwater, modular solidified slope protection, wave retaining wall, etc., wherein the rubber bag is filled with cement to form a modular solidified slope protection, but the solidified slope protection Due to the increase of resistance at the bottom, a downward impact is formed. Without buffer protection, the slope protection is easily hollowed out and the sea sand below forms a cavity, which eventually causes the slope protection to collapse, endangering the safety of the dam.
