- Q:Construction technology of geomembrane:
- Notes for geomembrane joints: (1) the joint treatment of the geomembrane is the key process of construction, which directly affects the service life of the project. Indicated by quality test, hot weiding is an ideal way. (special adhesive is also available). Heat welding method is heating the surface which is connected with the PE geomembrane, the surface melting, and then through the pressure to merge them into one, (2) Geomembrane shall be paved along a certain direction, on both sides of the geomembrane should be reserved for certain PE membrane and PET membrane bonding layer.While paving, we should adjust the tendency of geomembrane of each unit, in order to bring convenience to two units geomembrane welding. (3) Press geomembrane with sand bags to prevent wind after pavement, edge joints requires no dirt, moisture, dust, etc.. (4) before welding, adjust the joint at two sides of PE membrane, jointing them with broadband, and making them smooth, and no wrinkle. (5) When welding, it is better to have a technical personnel of certain experience, and use a special welding machine for welding. Adjust the temperature and speed, (can also use adhesive to bond). According to many years of practice, it is proved that the thickness of the geomembrane is not less than 0.25mm, because too thin is possible to produce porosity, and it is easy to be damaged in the construction to reduce the seepage control effect. During the construction of geomembrane, we should pay special attention that the pavement should not be too tight, shouldn't wrinkle, and the jointing should be firm. We should construct strictly according to the technical specifications, checking five quality clearance comprising preparation, paving, splicing joints, testing and backfill.
- Q:When can't PDHE impervious film be installed?
- It can not be installed in winter for the low temperature will affect the effect of construction and welding.
- Q:How do geomembranes contribute to the prevention of soil erosion?
- Geomembranes contribute to the prevention of soil erosion by acting as a barrier between the soil and external forces such as water, wind, or chemicals. They provide a protective layer to the soil surface, preventing it from being exposed to erosive factors and reducing the risk of erosion.
- Q:Are geomembranes suitable for wastewater treatment?
- Yes, geomembranes are suitable for wastewater treatment. They are commonly used in various treatment processes such as wastewater containment, lining, and capping systems. Geomembranes provide an effective barrier that prevents leakage, seepage, and contamination, ensuring the safe containment and management of wastewater.
- Q:How long can a mobile phone film use
- It depends on time you use your phone, if you play the game in a long time everyday, mobile phone film must have a short longevity. In general, a film can use two or three years. And, if you protect it well, you can use it until you do not want to use it.
- Q:Where does the smooth surface of seepage-proof geomembrane face?
- Negative direction that can increase frictions.
- Q:How do geomembranes contribute to erosion control in bridge and culvert construction?
- Geomembranes contribute to erosion control in bridge and culvert construction by providing a protective barrier that prevents water from infiltrating the soil and causing erosion. They act as a waterproof lining, effectively reducing the flow of water and preventing it from eroding the surrounding soil. This helps to maintain the structural integrity of bridges and culverts, ensuring their long-term stability and reducing the need for costly repairs or replacements.
- Q:How do geomembranes prevent water leakage in swimming pools?
- Geomembranes prevent water leakage in swimming pools by acting as a waterproof barrier. These flexible membranes are placed beneath the pool's lining or concrete shell to create a watertight seal, preventing water from seeping through the pool structure. The geomembrane, usually made of high-density polyethylene, blocks any water leakage by providing an impermeable layer that resists water penetration. Additionally, the geomembrane is durable and resistant to ultraviolet (UV) rays, chemicals, and other potential sources of damage, ensuring long-lasting protection against water leakage in swimming pools.
- Q:Can geomembranes be used in agricultural pond liners?
- Yes, geomembranes can be used in agricultural pond liners. They are commonly used to prevent water leakage and seepage, providing an effective barrier for containing water in agricultural ponds.
- Q:What's the question need to notice about the construction method of composite geo-membrane?
- Before laying HDPE geomembrane, there should be qualified acceptance documents of civil engineering. 2. Before cutting HDPE membrane, its size should be accurately measured, and then cutting according to the actual size, it commonly should not be cut according to the actual size but should be numbered one by one, and be detailedly recorded on the special form. 3. When laying HDPE geomembrane, welding line quantity should be controled, on the premise of guaranteeing quality, we should try best to save raw materials. At the same time, it's easy to ensure the quality. 4. The joint width of seam between film and film is generally more than 10 cm, usually make the welding line direction parallel to the maximum gradient, namely along the gradient direction. 5. Usually, in a corner and abnormal section, seam length should be shorten as far as possible. In addition to the special requirements, in slope greater than 1: Within the scope of 1.5 meters away from the slopes top or the stress concentration area, welding line should not be set up as far as possible. 6. While laying HDPE geomembrane, in order to avoid artificial fold, when the temperature is lower, we should try to tighten, paving the film. 7, after paving the HDPE geomembrane, walking or moving tools on the film should be avoided as far as possible, the things that will danger the HDPE geomembrane should not be placed on the fil, or carried while walking on the film, to avoid the accidental harms.
