Problems solved by technology

Most of the floating barrels are made of oil barrels or plastic barrels. The oil barrels or plastic barrels are hollow to form a bracket, and then fish nets are surrounded on the bracket to form; the cage with this structure is inconvenient to move, and the oil barrel is made of metal. It is easy to rust or corrode when used, which will affect the use effect and cause certain pollution to seawater.
And the net cage of this structure is inconvenient to adjust in the depth of water, is unfavorable for the use of typhoon weather
[0003] In addition, traditional cage materials have low strength, poor durability, and poor ability to withstand typhoons. Often a typhoon can cause heavy losses to farmers. Therefore, the development of various high-performance cages has become a current hot spot

Embodiment 1

[0042] Take the raw materials for preparing the support column: 400 parts of cement, 700 parts of sand, 850 parts of crushed stone, 180 parts of water, 4 parts of water reducing agent, EPS200L / m 3 and then mix the above-mentioned raw materials evenly according to the proportion, pour them into the mold of the supporting column, and carry out curing. After the maintenance is completed, the support column is taken out, and the anti-corrosion paint is coated on its surface.

Embodiment 2

[0044] Take the raw materials for preparing the support column: 390 parts of cement, 720 parts of sand, 725 parts of crushed stone, 190 parts of water, 3.5 parts of water reducing agent, EPS300 L / m 3 and then mix the above-mentioned raw materials evenly according to the proportion, pour them into the mold of the supporting column, and carry out curing. After the maintenance is completed, the support column is taken out, and the anti-corrosion paint is coated on its surface.

Embodiment 3

[0046] Raw materials for preparing support columns: 390 parts of cement, 750 parts of sand, 600 parts of gravel, 185 parts of water, 4 parts of water reducing agent, EPS300 L / m 3 and then mix the above-mentioned raw materials evenly according to the proportion, pour them into the mold of the supporting column, and carry out curing. After the maintenance is completed, the support column is taken out, and the anti-corrosion paint is coated on its surface.

[0047] The particle size of EPS (expanded polystyrene) in the above-mentioned embodiments of the present application is 3-5 mm; too large will affect the strength of the support column as a whole, and too small is not conducive to dispersion.

[0048] The performance of the lightweight concrete that above-mentioned embodiment obtains is as shown in table 1 below:

[0049]

[0050] From the above examples and experimental test data, it can be known that the support column prepared by the present application has the advanta...

Abstract

The invention discloses a multifunctional assembly type concrete seawater net cage. The net cage comprises a body support and a fishing net arranged on the support. The body support comprises a plurality of assembled supporting columns, column bodies of the supporting columns are made of lightweight concrete, the interiors of the supporting columns are axially hollow, reinforcing ribs are axially arranged in the side walls of the supporting columns, and the reinforcing ribs extend out of the ends of the supporting columns and are provided with threads. The supporting columns are hollow to form accommodating cavities, and inflatable air bags are arranged in the accommodating cavities; and an adapter is arranged between every two adjacent supporting columns, and the supporting columns are connected through the adapters to form the body support. Each adapter comprises a square hollow body, an operation hole is formed in each square hollow body, installation holes are formed at the periphery of each operation hole, and the installation holes are used for the reinforcing ribs to penetrate through and are connected with the supporting columns through the operation holes. The multifunctional assembly type concrete seawater net cage has the advantages that the multifunctional assembly type concrete seawater net cage can reasonably float up or sink down according to needs, is suitable for typhoon weather, cannot be corroded to cause pollution, and is convenient to move and drag.

Description

technical field [0001] The present application relates to the technical field of seawater net cages, in particular to a multifunctional prefabricated concrete seawater net cage. Background technique [0002] Seawater cage culture is a culture method commonly adopted along the coast of my country. There are many ways of cage culture. It is a common practice for farmers to choose a floating platform built with buoys and use fishing nets to form a natural fishery. Most of the floating barrels are made of oil barrels or plastic barrels. The oil barrels or plastic barrels are hollow to form a bracket, and then fish nets are surrounded on the bracket to form; the cage with this structure is inconvenient to move, and the oil barrel is made of metal. Use is prone to rust or corrosion, which affects the use effect and causes certain pollution to seawater. And the depth adjustment of the net cage of this structure is inconvenient in water, is unfavorable for the use of typhoon weathe...
