Construction method for enclosure structure unit of water-area ecological breeding pasture as well as enclosure structure unit and application thereof

Abstract

The invention discloses a construction method for an enclosure structure unit of a water-area ecological breeding pasture as well as the enclosure structure unit and application thereof. The enclosure structure unit comprises at least two concrete tubular piles which are mutually spaced and fixed in a water area, and a grating net connected between every two concrete tubular piles, wherein the construction of each concrete tubular pile is combined with a specific outer retaining wall indwelling layer or an outer retaining wall sleeve, and a concrete cast-in-place method is adopted, so that the concrete tubular pile is quickly formed. The enclosure structure unit is utilized to enclose the water area into an ecological breeding pasture which can perform water exchange with the outside. The construction method for the enclosure structure unit of the water-area ecological breeding pasture as well as the enclosure structure unit and application have the advantages that through the technology, an enclosure structure unit which is strong in wind and wave resistance and efficient and fast in construction can be processed, thereby further forming a water-area ecological breeding pasture, which is conducive to promoting development and utilization of water area resources, especially the marine resources, and economic and social development.

Description

technical field [0001] The invention belongs to the fields of construction engineering and water area breeding, and in particular relates to a construction method of an enclosure structure unit of a water area ecological breeding pasture, the enclosure structure unit and its application. Background technique [0002] With the development of the marine economy, it has gradually become the consensus of the society to increase the development and utilization of fishery resources such as the ocean. Mariculture is a production method for the development of marine fishery resources. It uses specific waters and adopts artificial measures to promote the reproduction and growth of marine organisms, especially the special fish with high economic value, such as yellow croaker and grouper. , red snapper, pomfret and other valuable fish. [0003] At present, my country's mariculture mainly adopts cage culture and seine culture. Among them, cage culture uses metal, plastic, bamboo and ...

AI Technical Summary

Problems solved by technology

[0004] (1) The ability to resist wind and waves is poor, so it is limited to the inner bay with good sheltered conditions, which leads to poor water exchange conditions and high-density breeding for a long time, which deteriorates the bottom and water quality conditions of the inner bay, resulting in slow growth of fish and prevalence of diseases. poor ecological efficiency;

[0005] (2) In order to prevent attachments from clogging the mesh, it is necessary to change and wash the cage frequently, and at different stages of fish growth, it is necessary to replace the net with the mesh size corresponding to the expected size of the fish. At the same time, in order to maintain the water environment and prevent the spread of pathogens, regular cleaning is required. Fishing out the dead fish in the box has a large workload, low labor efficiency, poor working environment for fishermen, and inconvenient management;

[0006] (3) The size of the net cage is relatively small, the breeding efficiency is low, and due to the limitation of the size of the net cage, the space for fish to move is small, and the water environment is poor, making the fish generally short and fat, with poor color, poor meat quality and taste , low nutritional value;

[0007] (4) It is difficult for traditional cage culture to drive the development of other subsidiary industries such as recreational fishery, and the social benefits are not significant

[0009] (1) For tidal flat fence farming, due to the existence of dikes and dams, the tidal flow velocity is greatly slowed down, a large amount of sediment is deposited in the farm, and there is only water exchange between inside and outside the fence at high tide, resulting in poor water exchange and disease. This method is based on tidal flats, and the sea water level is shallow, so it is only suitable for breeding scallops, oysters, etc., and is not suitable for fish farming;

[0010] (2) The development form of the harbor fence is simple, but it is only separated by fishing nets, and its ability to resist wind and waves is poor
