Problems solved by technology

[0004] 1. For fish reefs built by artificial shipwrecks, most of the sunken ships are made of steel, which is easy to corrode in seawater, and the durability does not meet the requirements; secondly, the discarded materials in the hull may cause pollution to the marine environment; in addition, the sunken ships In shallow sea areas may affect the safety of navigation of ships
[0005] 2. If traditional commercial concrete is used to build fish reefs, freshwater and fresh sand resources are scarce in the marine environment, which cannot meet the raw material needs of large-scale concrete mixing on site; if seawater and sea sand are used to directly replace fresh water and fresh sand to prepare concrete, the The coarse aggregate is c

Abstract

An underwater artificial fish reef prepared from seawater, sea sand and a non-gold rib material, and having a self-repairing function is disclosed. The artificial fish reef is prepared from the non-gold rib material and seawater-sea sand high-toughness concrete. The non-gold rib material is at least one of BFRP, CFRP, GFRP fiber composite rib materials. The seawater-sea sand high-toughness concrete includes, by weight, 20-30 parts of PVA fibers, 750-830 parts of first-grade fly ash, 500-551 parts of ordinary Portland cement, 380-415 parts of sea sand, 300-326 parts of seawater and 2.5-8.3 parts of a polycarboxylate superplasticizer. The non-gold rib material is utilized to replace traditional reinforcing steel bars so that the problem that reinforcing steel bars are corroded under sea is solved radically. The concrete utilizes local materials, and raw materials are easily available. The artificial fish reef has a low cost, good durability, high toughness, high deformation capability, crack harmless dispersing capability, excellent freezing and thawing resistance, good shock resistance, good energy consumption performance, and the high self-repairing function for damage.

Description

technical field [0001] The invention relates to an underwater building in the ocean, in particular to an underwater artificial fish reef with seawater and sea sand and non-golden reinforcement material with self-repairing function. Background technique [0002] Nowadays, the living space of human beings has gradually expanded to the ocean, and the development and construction of ocean islands is related to my country's core ocean rights and interests. At present, my country has reclaimed seven islands and reefs in the Nansha Islands (Yongshu Reef, Mischief Reef, Huayang Reef, Chigua Reef, Subi Reef, Nanxun Reef, Dongmen Reef). In order to solve the impact of reclamation on marine ecology Therefore, it is necessary and obligatory for us to implement the marine ecological restoration project on Nansha islands and reefs. The Nansha Islands and Reefs Marine Ecological Restoration Project can effectively repair the damage to the ecological environment of the islands and reefs cau...
