Construction of Smooth Geomembrane

The construction of smooth geomembrane is a process involving multiple links and details. The following is a detailed introduction to the construction of smooth geomembrane:

Preparation before construction

· Material selection:

Select a smooth geomembrane that meets the engineering requirements.

Check whether the geomembrane has obvious defects such as damage, oil stains, dust, etc.

· Base treatment:

Clean up debris, sharp objects, etc. in the construction area to ensure that the base surface is flat and free of irregularities.

Compact the base surface to ensure its compactness meets the requirements.

· Construction tools and equipment:

Prepare the necessary tools and equipment for construction, such as hot melt welding machines, cutting blades, brushes, measuring tools, etc.

Construction method

· Smooth geomembrane laying:

Lay the geomembrane on the construction site according to the engineering design requirements and actual needs.

When laying, attention should be paid to the direction of the geomembrane, making it as parallel as possible to the maximum slope line.

During the laying process, artificial wrinkles should be avoided and the geomembrane should be tightly adhered to the base surface.

· Cutting and splicing:

Cut the geomembrane according to the actual size. Before cutting, each piece of geomembrane should be numbered and the relevant dimensions recorded.

At the location where splicing is required, hot melt welding technology is used to fuse different segments of geomembrane together. The joint should be flat, tight, and free of virtual welding, leakage welding, and other phenomena.

· Fixing and backfilling:

After the installation of the geomembrane is completed, it should be fixed in a timely manner. It can be fixed on the base surface with heavy objects such as nails and sandbags.

After the fixation is completed, carry out backfilling work. Backfilling should be carried out in layers, and the thickness and compaction of each layer of fill should meet the design requirements.

Construction precautions

· Environmental requirements:

The construction environment temperature should be suitable, and construction should be avoided at temperatures that are too low or too high.

Welding operations are prohibited in rainy, humid, dewy, or heavily dusty conditions unless appropriate protective measures are taken.

· Welding quality:

Before welding, the welding surface should be cleaned to ensure that there are no oil stains, dust, or other debris.

When welding, a generator with good voltage regulation performance should be used for power supply. In special cases where a local power source is used, a voltage regulator must be equipped.

After welding is completed, quality inspection should be carried out on the weld seam to ensure that it meets the design requirements.

· Construction efficiency and safety:

Reasonably plan the construction process and improve construction efficiency.

During the construction process, attention should be paid to safe operation, wearing protective equipment to avoid accidents.

Post construction maintenance

· Regular inspection:

Regularly inspect the geomembrane to check for any damage, cracking, or other issues.

· Timely repair:

If any damage or cracking is found in the geomembrane, it should be repaired or replaced in a timely manner.

· Cleaning and maintenance:

Regularly clean the debris and dust on the surface of the geomembrane to maintain its cleanliness and smoothness.
