Problems solved by technology

But above-mentioned artificial fish reefs of these prior art all have certain deficiency more or less: the shortcoming of such as common reinforced concrete: steel bar is easy to corrode, causes concrete to crack, collapses at last, therefore, general common reinforced concrete fish reef only has two The lifespan is about ten years, and the lifespan is short; in addition, the old tire reefs have certain pollution to the water body, while the steel reefs affect the seabed environment
[0004] At present, with the continuous development of the real estate industry, a large number of residential buildings are dismantled and turned into construction waste, which will lead to the generation of a large amount of construction waste, causing environmental pollution and not being effectively utilized

Embodiment 1

[0022] (1) Reinforced concrete cutting: After processing the residential frame to be dismantled with tools such as jacks, pneumatic hammers, and hydraulic hammers, use a steel bar cutter to cut off the steel bars, and use water to cool them to obtain a residential frame structure;

[0023] (2) Cutting treatment: use silicone emulsion as the waterproof coating on the end face of reinforced concrete for surface coating, the coating penetrates into the concrete surface 2-3mm to form a waterproof layer, thereby preventing seawater from entering; then use cured fluorocarbon resin The paint is applied with a top coat and dried;

[0024] (3) Reinforced concrete surface treatment: Spray mortar on the surface of the concrete to make the surface uneven; mix the components including water into a wet material in advance according to the proportion, and send the dehumidified material to the The spray gun, and the compressed air input near the muzzle sprays the wet material, forming an unev...

Embodiment 2

[0034] The raw materials of the mortar include: 20 parts of cement, 50 parts of slag, 12 parts of steel slag, 8 parts of alkali slag, 12 parts of propylene milk, 1 part of manganese-containing waste slag, 25 parts of machine-made sand or concrete waste slag, polycarboxylic acid air-entrained reducing 0.01 part of water agent, appropriate amount of water. Others are with embodiment 1.

Embodiment 3

[0036] The raw materials of the mortar include: 12 parts of cement, 25 parts of slag, 10 parts of steel slag, 6 parts of alkali slag, 10 parts of propylene milk, 1 part of manganese-containing waste slag, 16 parts of machine-made sand or concrete waste slag, polycarboxylic acid air-entrained reducing 0.008 part of water agent, appropriate amount of water. Others are with embodiment 1.

[0037] The technical indicators of the sprayed mortar of the present invention: the compressive strength is greater than 23MPa, and the bonding tensile strength is greater than 1.5MPa.

Abstract

The invention discloses a method of manufacturing an artificial fish reef with a residence frame to be disassembled. The method includes the preparing steps of cutting reinforced concrete of the residence frame to be disassembled, processing notches and processing the surface of the reinforced concrete. In the notch processing step, organosilicon emulsion is used as a waterproof coating for the fracture face of the reinforced concrete, surface coating is conducted, the coating permeates into the surface layer of the concrete by 2-3 mm to form a waterproof layer, and consequently sea water is prevented from entering; cured type fluorocarbon resin paint is used for forming a finishing coating, and then the finishing coating is dried. The method has the advantages of being low in manufacturing cost, capable of effectively using the residence frame to be disassembled and reducing environment pollution, low in heavy metal content and beneficial for fish shoal elusion or survival and achieving resource recycling.

Description

technical field [0001] The invention relates to the technical field of artificial fish reefs, in particular to a method for making artificial fish reefs by using a residential frame to be demolished. Background technique [0002] Artificial reefs refer to artificial facilities that are composed of one or more natural or artificial objects and are purposefully placed in the sea to improve the ecological environment, increase fishery resources, and promote social and economic development. The artificial reef construction project is one of the marine fishery ecological projects emerging in the 20th century, and is an important part of the marine ranching system engineering. The construction of artificial reefs is beneficial to the improvement of marine land, the construction of marine ranch, the adjustment of marine industry structure, the promotion and optimization of marine industry, the development of marine tourism and related industries, the restoration and improvement of ...
