Problems solved by technology

[0004] During the restoration process of the coral reef ecosystem, the bottom of the damaged and collapsed degraded coral reef area is mostly broken coral gravel debris. The gravel and sandy debris will roll and migrate under the drive of the water flow, and cannot be attached to the reef-building coral larvae Provide a stable substrate, and the rolling of coral debris will also cause mechanical damage such as collision and friction to newborn and artificial bottom-seeded reef corals, which is not conducive to the artificial restoration and natural restoration of coral reef ecosystems

Embodiment 1

[0025] Add 20% (mass fraction) of epoxy resin with adhesive basalt fiber (diameter 10mm), composite basalt fiber (that is, two parallel parallel ∮ 1mm 1A50 industrial pure Aluminum and aluminum wires 2, and run up and down on the surface of the basalt fiber bundle at intervals of 5cm, such as figure 1 with figure 2 shown), cement board, plastic board and aluminum alloy board as materials. The glued basalt fiber or composite basalt fiber is woven into a grid, and the hole diameter of the grid is 5cm.

[0026] All the above-mentioned experimental materials were cut into a size of 15cm*15cm. Cement blocks were soaked in pre-circulated seawater tanks for 56 days and other materials for 25 days. The experimental corals used staghorn cup-shaped coral floating larvae, and put them into 3L glass beakers for attachment culture after counting. Each glass beaker contained an experimental material, and all experimental group beakers were bathed in the same water tank system to ensure ...

Embodiment 2

[0033] Such as figure 1 , figure 2 with image 3 As shown, the environment-friendly composite basalt fiber reef grid suitable for coral reef bottom restoration in this embodiment includes a square (3*3m) grid woven from glue-free basalt fiber bundles 1 with a diameter of 10mm. The single-grid grid in the grid is a square with a side length range of 80 mm. Each glue-free basalt fiber bundle 1 is embedded with 2 parallel ∮1mm1A50 industrial pure aluminum wires 2, and runs up and down on the surface of the basalt fiber bundle at an interval of 5cm. The grid is folded inward along the four sides and folded and sewn with basalt fiber cloth to form a set Tubular, forming a casing 3, the inner diameter of the casing is not less than 25mm for the support and fixing steel bars (fixing pipe) of ∮16mm, and one side of the middle part of the grid also needs to be sewn with basalt fiber cloth to form a casing 3 and fixed on it The middle part of the grid is used to pass through ∮16mm s...

Abstract

The invention discloses an environment-friendly composite basalt fiber reef base grating suitable for coral reef substrate repairing and a repairing method. The grating comprises a square grid formedby weaving binderless basalt fibers, pure aluminum wires are woven in the binderless basalt fibers in an embedded mode, sleeves made of basalt fiber cloth are fixedly connected to the four sides of the grid along edges, sleeves made of the basalt fiber cloth are also arranged in the middle of the grid, and fixing connecting holes are formed in the four corners of the grid. The team of the invention has already applied the environment-friendly composite basalt fiber reef base grating to multiple coral reef ecological repairing projects of South China Sea tropical coasts and island reef sea areas, accumulative application and repairing area reaches 4000 m<2>, and a good repairing demonstration effect is achieved.

Description

Technical field: [0001] The invention belongs to the field of coral restoration, and specifically relates to an environment-friendly composite basalt fiber reef-based grid and restoration method for coral reef ecological restoration projects, which are suitable for coral reef ecological restoration projects in tropical coral reef areas, broken reef rocks, coral gravel, coral Basement stabilization and sediment reformation in clastic sediment type sea areas. Background technique: [0002] The coral reef ecosystem is called the tropical rainforest in the ocean. It is the life soul and protector of coral islands and reefs. It has important ecological functions of protecting islands and reefs. It is of great significance to stabilize the structure of islands and reefs and create a livable environment. There are more than 200 coral islands, reefs and sandbars in the South my country Sea. It is one of the most abundant areas of marine coral reefs in the world. It provides habitat...
