Description

A kind of new shell base concrete fish shelter
Technical field
The invention belongs to marine environment prosthetic device field, and in particular to a kind of new shell base concrete fish shelter.
Background technology
It is well known that a large amount of shells are accumulated on some seashores, also abandoned in coastal cities marine products processing factory and house refuse A considerable number of shell, closely by taking the marine site of Zhoushan Shengsi as an example, annual caused shell is approximately the five of annual house refuse heap / mono-, quantity is about 90,000 tons.These shells will be transported to specified refuse landfill landfill disposal, can come to urban belt huge Financial burden.On the other hand, concrete is made according to the conventional method, to consume the sandstone of 70% or so parts by weight.To obtain this A little sandstones often collapse mountain exploitation, excavate river course, destroy natural landscape, consume substantial amounts of natural resources, to lead gangster into a trap shallow.
Artificial marine habitat construction project is one of sea fishery ecological engineering risen in 20th century, is aquafarm system engineering Important component, the construction of artificial marine habitat to regulation marine territory, build aquafarm, adjustment marine industry constitution, promote Enter the upgrading and optimization, the development for driving maritime travel and related industry, reparation and the improvement marine eco-environment, increasing of marine industries Grow and optimize fishery resources, rescue Precious, Rare, Endangered is biological and protects bio-diversity, promotes marine economy sustainable and healthy development etc. It is respectively provided with great strategic importance and far-reaching historic significance.
Show according to relevant result of study, due to the otherness of the crystalline state of different fish reef materials and molecular structure etc., make They have different decay resistances in the seawater, and this just determines its income years after use is launched, also will be to it Caused economic benefit has a huge impact, and effect differs caused by the fish shelter of different types of structure.
The content of the invention
It is an object of the invention to provide a kind of new shell base concrete fish shelter, and natural sand stone is replaced using waste shell Concrete fish shelter is made as aggregate, the fracture toughness of fish shelter is strong, and hydrodynamic performance and compression strength are good, and stability is strong, prepares Fish reef structure can improve the distribution of nutriment in seawater.
The scheme taken to achieve the above object of the present invention is:A kind of new shell base concrete fish shelter, the system of fish shelter Standby technique is as follows, the preparation of coarse crushing shell, the preparation of oyster shell whiting, the preparation of concrete fish shelter, and the above method uses waste shell Concrete fish shelter is prepared as major ingredient instead of natural sand stone and part of cement, has accomplished resource reutilization, and is advantageous to environment guarantor Shield, the fracture toughness of the fish shelter of making is strong, and hydrodynamic performance is good, and stability is strong, and it is low to prepare cost.
Preferably, the preparation process of coarse crushing shell is:Waste shell is cleaned 2-3 times with cleaning fluid, at 100 DEG C ~ 200 DEG C Under the conditions of dry 1.5 ~ 2h, and grind into 1 ~ 20mm particles, sieve, obtain coarse crushing oyster shell whiting, the above method is to waste shell Clean the debris and spot for effectively removing shell surface, have in the fish shelter for avoiding subsequently preparing containing spot to shoal of fish health Influence, the moisture that drying and processing is effectively removed in shell is carried out to shell and is advantageous to the efficiency ground and effect, coarse crushing Oyster shell whiting also has good adsorption effect, and the fish shelter for being advantageous to prepare adsorbs fine pollutants and heavy metal ion in water, Obtained coarse crushing shell can replace natural sand stone to reduce the preparation cost of fish shelter as fish shelter principal component, be additionally favorable for environmental protection.
Preferably, cleaning fluid is made up of following component and parts by weight:Disodium ethylene diamine tetraacetate 10-18 parts, octadecyl Dihydroxy ethyl amine oxide 12-22 parts, dipotassium glycyrrhizinate 10-24 parts, paradime thylaminobenzaldehyde 0.04-0.08 parts, dodecyl Benzene sulfonic acid sodium salt 8-25 parts, metasilicate pentahydrate sodium 5-12 parts, cocoanut fatty acid diethanolamide 4-17 parts, aliphatic alcohol polyethenoxy Ether 5-15 parts, deionized water 10-50 parts, the spots such as the sludge of discarded shell surface or greasy dirt, cleaning are imitated using cleaning fluid Fruit is quick, noresidue, fully anti-with other compositions after addition paradime thylaminobenzaldehyde in cleaning agent to shell non-corrosiveness Cleaning agent cleaning performance after answering significantly increases, while cleaning agent can form one layer of resistant to elevated temperatures anti-corrosion film in shell surface, Strengthen the anticorrosion ability of shell surface.
Preferably, the preparation process of oyster shell whiting is:Coarse crushing oyster shell whiting in part is taken to add auxiliary agent, in 380 DEG C ~ 450 DEG C of horse Not kiln roasting 25-38min, cooling grinding, crosses 480-560 mesh mesh screens, obtains oyster shell whiting, further to coarse crushing shell by being calcined Processing, moisture, sulphur, organic matter in oyster shell whiting are removed, change shell physical property, the enhancing gained cementing effect of oyster shell whiting, have Fracture toughness, hydrodynamic force beneficial to the fish shelter of preparation ask you to drink stability.
