Concrete box-type fish shelter

Abstract

The invention provides a concrete box-type fish shelter. The concrete box-type fish shelter comprises a cubic fish shelter body prepared from a concrete structure, the inside of the fish shelter bodyis hollow, a front opening is formed in the right side of the front face of the fish shelter body, and a rear opening is formed in the left side of the rear face of the fish shelter body. Two parallelleft openings are formed in the upper side of the left face of the fish shelter body, two parallel right openings are formed in the lower side of the right face of the fish shelter body, two upper openings are formed in the middle of the upper face of the fish shelter body, and a bottom opening is formed in the middle of the bottom face of the fish shelter body. The concrete box-type fish shelteris of a reinforced concrete structure, only a ring beam is arranged on the bottom face, the contact area with the seabed is small, benthos is little influenced, two convection openings are formed inthe upper side and the lower side of the left face respectively, and two convection openings are formed in the upper side and the lower side of the right face respectively. Water inflows from the topand outflows from the bottom or inflows from the bottom and outflows from the top, the seawater flow rate is reduced, a stable water environment is provided for fishes, and water stagnation cannot beformed in the fish shelter.

Description

technical field [0001] The invention relates to a fish reef, in particular to a concrete box type fish reef. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. At present, the construction of artificial reefs has been widely carried out at home and abroad, and the restoration of offshore marine habitats and fisheries has been carried out, and good results have been achieved. At present, almost all the artificial reefs put in the marine ranch in our country are made of ordinary reinforced concrete. In the environment of seawater erosion, the durability of the reef structure is often poor due to concrete cracking and premature corrosion and expansi...

Problems solved by technology

At present, almost all the artificial reefs put in the marine ranch in our country are made of ordinary reinforced concrete. In the environment of seawater erosion, the durability of the reef structure is often poor due to concrete cracking and premature corrosion and expansion of steel bars. ideal
