Five Environmental Requirements for the Construction of Anti-seepage Membranes for Lotus Pond Aquaculture

As we all know, the installation of anti-seepage membranes for lotus pond aquaculture places stringent demands on both technical expertise and weather conditions. Both the initial planning and the welding of welds during installation are extremely challenging, and weather requirements are even more stringent. Standard values ​​for both wind speed and temperature are required. Today, we will explain the five environmental requirements for the construction of anti-seepage membranes for lotus pond aquaculture.

1. During the installation of anti-seepage membranes for lotus pond aquaculture, artificial wrinkles should be avoided. When temperatures are low, the membrane should be stretched tight and laid flat. After the membrane is installed, walking and moving tools on the membrane surface should be minimized. Any objects that could damage the membrane should not be placed on or carried while walking on it to prevent accidental damage.

2. Climate Requirements for the Construction of Anti-seepage Membranes for Lotus Pond Aquaculture: The temperature should generally be above 5°C. The membrane should be stretched tighter in cold weather and looser in hot weather. During the installation of the geomembrane for lotus pond aquaculture, allow for a 2%-5% expansion margin based on specific site conditions and prevailing weather conditions. Construction should generally be avoided when wind speeds are below level 4, temperatures are extremely low, wind speeds are above level 4, or in rainy or snowy weather. In windy weather where wind speeds may affect geomembrane installation, the geomembrane to be welded should be held down firmly with large rocks or sandbags.

3. A critical step is to inspect the surface quality of the geomembrane before laying. Any mechanical damage, production trauma, holes, breakage, and other defects should be recorded and repaired. Before cutting the geomembrane for lotus pond aquaculture, the relevant dimensions should be measured and then cut to the required dimensions. During installation, the overlap width between the membranes should be 10-15 cm, and the seams should be aligned parallel to the toe of the slope, i.e., aligned with the slope.

4. Requirements for the construction of anti-seepage membranes for lotus pond aquaculture: The base surface must be compacted and leveled, and sharp objects such as tree roots, stones, glass, and nails must be removed. Corners must be rounded to a radius of ≥50cm, and weld seams must be cleaned. After acceptance and approval by the civil engineering, supervisor, owner, and contractor, the membrane can be laid.

5. Installation of the membrane: When installing the membrane, the seams of the membrane are aligned parallel to the toe line, i.e., along the slope. When installing the membrane, minimize welds, conserving raw materials while ensuring quality, and ensuring quality assurance. Generally, weld lengths should be minimized at corners and in irregular locations. Unless otherwise specified, welds should be avoided within 1.5m of the top slope or stress concentration areas on slopes greater than 1:6.

The above are the five environmental requirements for the construction of anti-seepage membranes for lotus pond aquaculture. I hope it will be helpful for everyone to lay anti-seepage membranes for lotus pond aquaculture in the future.
