Slope protection structure and construction method of sea cucumber culture pond

Abstract

The invention provides a slope protection structure of a sea cucumber culturing pond and a construction method thereof, wherein the slope protection structure and the construction method belong to the field of aquaculture. The slope protection structure comprises a freshwater discharging trench, a slope upper edge, a slope surface, fixed pendants and a slope lower trough. The freshwater discharging trough is arranged at the central part in a pond dam and forms an independent ditch along the longitudinal direction of the pond dam. The slope upper edge extends along the dam body and is forms a ridge-shaped member above the pond dam. The slope upper edge is connected with the upper end of the slope surface of the pond. The lower end of the slope surface of the pond is connected with the bottom of the pond. An included angle is formed between the slope surface of the pond and the bottom surface of the pond. The lower end of the slope surface extends to the portion below the bottom surface of the pond along the slope surface, thereby forming the slope lower trough of a recessed structure. The portion above the slope lower trough is compressed by soil at the bottom of the pond. Fixed pendants are arranged on the slope surface in a laying manner. The materials of the slope protection are characterized in that a canvas layer is laid in a manner of clinging to the ground and a cement mortar is laid above the canvas through high-pressure injection. The slope protection structure has advantages of simple laying, low cost, long service life and easy popularization.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a slope protection structure and a construction method of sea cucumber culture ponds. Background technique [0002] Sea cucumber farming mainly includes pond culture, factory culture, hanging cage culture, cage culture and other modes. Among them, pond culture is one of the main farming models in northern my country, which has the advantages of easy control of the breeding environment, simple process, considerable yield and benefits. In the process of pond cultivation, strong wind and rain can easily lead to the collapse of the pond dam, turbidity of pond water, and fresh water injection, which is not good for sea cucumber cultivation. Therefore, it is very necessary to carry out slope protection in the process of pond construction or transformation. [0003] Firm slope protection can not only protect the pool dam from collapse or cloudy water, but also an important activ...

AI Technical Summary

Problems solved by technology

The slope body of woven fabric slope protection is vulnerable to the impact of water waves, and the soil under the fabric will be lost until it finally collapses, and natural bait such as benthic algae should not be attached to the woven fabric; in addition, under the condition of high temperature or poor water flow, woven fabric and its fabric The soil under the body is prone to rancidity, sea cucumbers do not like to inhabit

Although simple cement slope protection can grow and attach a large amount of benthic algae, due to the simple process of slope protection, the slope body is not firm. With the extension of cultivation time, the cement slope protection is easy to loosen and eventually collapse.

There are also major problems in masonry slope protection: one is that the bricks are easily corroded by seawater and their service life is not long; the other is that the cost of the stones is relatively high; the third is that these two materials are not conducive to the growth and sea ​​cucumber perch
