Fish pond geomembrane liner construction skills

Fish pond engineering essentials: geomembrane construction skills

With the development of aquaculture, the construction of fish ponds has become an important area. In the construction of fish ponds, the use of geomembranes is becoming more and more common. Geomembrane has the characteristics of waterproof, impermeable and anti-aging, which can effectively maintain the ecological environment of fish ponds and ensure the quality and output value of fish farming. However, geomembrane construction is an important work in fish pond engineering, and its construction quality directly affects the aquaculture efficiency and engineering quality of fish ponds. Therefore, this paper focuses on the geomembrane construction skills, and summarizes some necessary geomembrane construction skills for fish pond engineering, hoping to help you.

1. Geomembrane material

The main materials of geomembranes include polyethylene, polypropylene and other synthetic materials. According to different application needs, geomembranes with different thicknesses can be selected. When choosing geomembrane materials, we should choose suitable products according to the specific conditions of the fish pond, and ensure that the quality of the products meets the national standards.

2. Outdoor construction

Outdoor construction needs to pay attention to the following aspects:

1. Basic processing

The foundation of the fish pond should be level, solid, without obvious depressions, and eliminate acute angles and edges. After the foundation treatment is done, the geomembrane is laid.

2. Material splicing

When laying the geomembrane, the diaphragm should be cut and spliced. The splicing of the diaphragm should be spliced with a special welding machine to ensure that the splicing is tight and there is no water leakage. At the same time, the treatment of the splicing should fully take into account the needs of future maintenance and restoration.

3. Construction temperature

In the process of outdoor construction, the influence of temperature should be fully considered, and the appropriate time should be selected for film laying. Most geomembranes need to be applied at a temperature of around 20°C, otherwise the diaphragm will become brittle and easily damaged.

3. Indoor construction

Indoor construction needs to pay attention to the following aspects:

1. Ground treatment

The site for laying geomembranes indoors often exists on the basis of open ground, so it is necessary to do a good job of ground treatment before laying. It should be ensured that the base surface is neat, flat, free of dust, and that there is no gradual substance that is strongly sticky to the film.

2. Welding skills

For indoor geomembrane laying, welding skills are particularly important. When welding the connection, the welding margin should be left sufficient, and the heating should be uniform, and the welding place should be fixed and firm.

3. Bubble treatment

During the laying process, air bubbles may appear and need to be dealt with in a timely manner. If not handled properly, air bubbles can have an adverse effect on the geomembrane.

Precautions during construction

1. Strictly implement the construction plan to ensure that every detail is paid attention to and properly handled.

2. Before splicing and welding, the contact surface should be treated.

3. Do not expose the sun directly to the membrane surface, you can shade the rain and attach a membrane cover that can be cut to avoid direct sunlight.

4. When carrying out ground treatment, the surface layer of the soil should be removed.

5. Considering the future maintenance and repair, some margin should be left during construction for future maintenance and repair.

The construction quality of the fish pond geomembrane is directly related to the breeding benefits and maintenance costs of the fish pond. Therefore, before construction, we must carefully formulate the construction plan, and deal with every detail in strict accordance with the standard requirements to ensure that the construction quality meets the standards. During the construction process, attention should be paid to safety issues to ensure the safety of staff. At the same time, after the construction is completed, a series of water quality tests should be carried out on the fish pond to ensure that the construction quality of the geomembrane meets the national standards.
