3D printing South China Sea island reef breakwater and manufacturing method thereof

Abstract

The invention discloses a 3D printing South China Sea island breakwater, and relates to the technical field of breakwaters, the 3D printing South China Sea island breakwater comprises a breakwater core stone, the breakwater core stone is laid on an island foundation, one side face of the breakwater core stone is obliquely arranged, cushion block stones are laid on the surface of the breakwater core stone, and a 3D printing concrete protective surface is printed on the upper surface of the cushion block stones through a 3D printer. The invention further discloses a manufacturing method of the 3D printing South China Sea island reef breakwater, and the manufacturing method comprises the four steps of early-stage material stirring, water reducing agent stirring, fiber stirring and 3D printing, so that the good decoration effect is achieved, and the concrete shrinkage cracking risk is reduced. The 3D concrete printing technology is applied to the construction of the breakwater of the island reef in the South China Sea, and the surface layer of the breakwater is printed into various wave-absorbing patterns and structures, so that the wave-absorbing effect is achieved, and a certain artistic aesthetic effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of breakwaters, in particular to a 3D printed South China Sea island reef breakwater and a manufacturing method thereof. Background technique [0002] The marine environment of islands and reefs is harsh, with wide water depths, active tropical cyclones, and prevailing monsoons. The anti-wave structures on islands and reefs are often close to the edge of the reef. Under the action of extreme waves such as abnormal waves, typhoon waves, and storm surges, the waves break. The subsequent wave-induced current directly impacts the anti-wave structures on islands and reefs. The magnitude of the wave force not only affects the structural stability of anti-wave structures, but also plays a decisive role in the safety of backfilling sand islands and the effective operation of other ancillary facilities on islands and reefs. role. Building breakwaters around the islands and reefs in the South China Sea can reduce the...

AI Technical Summary

Problems solved by technology

[0003] Breakwaters on islands and reefs in the South China Sea are generally composed of core stones, cushion stones and concrete armor, and concrete armor is generally composed of twisted king blocks. The existing breakwaters are mainly prefabricated components such as twisted king blocks, which are laid on islands. On the reef foundation, it is difficult to fit closely with the surface of the foundation, and the torsion king block needs to be prefabricated, so it is difficult to adjust according to the actual situation on site, thus affecting the effect of wave dissipation
