A kind of manufacturing method of aquaculture anti-escape fence cement pile

Abstract

The invention relates to a manufacture method for a concrete stake of aquiculture escape-proof fence, comprising the steps of combining a plurality of molding boards into a tubular molding board, respectively fixing a cylindrical upper bushing and a cylindrical lower bushing to the upper and the lower ends of the tubular molding board, fixing a cylindrical middle bushing to the middle part of thetubular molding board, erecting the molding board, sealing the lower end as the bottom of the molding board, opening the upper end of the molding board, inserting a reinforcing steel bar into the molding board, injecting the concrete into the molding board from the upper end, detaching the bushing after solidifying, separating the molding board for finishing the manufacture of concrete stake, andthen fixing the fence onto the stake with an iron wire or a clamp. The invention has the advantages that the molding board of the invention is detachable and reusable, the manufacture method is simple, the manufacture cost is low, the surface of the concrete stake is smooth, and the service life is long.

Description

technical field [0001] The invention relates to a structure of a cement pile for an anti-escape fence for aquaculture, in particular to a method for manufacturing the cement pile for an anti-escape fence for aquaculture, and belongs to the technical field of aquaculture. Background technique [0002] Escape prevention fences are usually required when raising river crabs, Procambarus clarkii or other aquatic species that are prone to escape. Except brick wall structure and glass structure, other anti-escape fences such as plastic plate structure, plastic film structure, calcium-plastic plate structure, metal structure or mesh structure all need to be piled and fixed to prevent the fence from collapsing. Common fence piles include wooden piles, bamboo piles, reinforced concrete piles and steel pipe piles, etc. Among them, steel pipe piles are strong, but high in cost and easy to rust; wood piles and bamboo piles are low in cost, but they are easy to rot and become brittle.

Problems solved by technology

Common fence piles include wooden piles, bamboo piles, reinforced concrete piles and steel pipe piles, etc. Among them, steel pipe piles are strong, but high in cost and easy to rust; wood piles and bamboo piles are low in cost, but they are easy to rot and become brittle. The lifespan is short, and when the fence pile is broken or collapsed in bad weather, the breeding organisms will often escape. Therefore, in order to ensure the reliability of the fence, it needs to be replaced every 2-4 years, and the cost performance is low.

Reinforced concrete piles have high strength and long service life, but the production of traditional reinforced concrete piles requires the production of steel frame first, which has certain technical difficulties in bundling, and requires a special site for cement pile casting, so it is suitable for specialized production. When it is used as a fence pile for aquaculture, it has the defect of high cost performance, which is not conducive to the reduction of aquaculture cost

In addition, the traditional reinforced concrete piles are mostly square columns with rough surfaces and flat bottoms. It is difficult to drive the piles, and the tops of the piles are easily broken. Less use of reinforced concrete piles

Wooden piles and traditional reinforced concrete piles are often climbed by predators such as mice, which are likely to cause harm to breeding organisms
