The anti-seepage geomembrane is a new type of synthetic geotextile waterproof barrier material produced in the 1980s.

As we all know, the main equipment for producing geomembrane in my country is divided into laminating machine and blown film machine. Of course, the equipment is getting more and more advanced, and the produced geomembrane has been greatly improved in terms of vision and physical chemistry. So, how are the blue and green impermeable geomembrane processed? In theory, in actual design, users usually design with black and green on the other side or blue on the other side. In addition, when the two sides are colored, they are used for special projects. It is called black green and black blue. If you simply produce reverse osmosis membranes with the same color on both sides, you can make a laminating machine. When producing black-green or black-blue impermeable membranes, blow molding equipment is required for processing. Special masterbatch materials and ultraviolet strong carbon black are added in the production process, which has excellent durability.

In fact, waterproof geotextile is also known as geotextile. Its total width is 4-6 meters, and its total length is 50-100 meters.

Do you know? As the name suggests, geotextiles are industrial "cloths" formed by weaving and synthetic fibers. They are generally divided into woven and non-woven fabrics. Textile means that the raw materials are woven by traditional machines. Non-woven fabric refers to the bonding of raw materials into a cloth shape by thermal melting or other physical methods. The most common wet wipes use non-woven materials. Geomembrane is similar to plastic bags that are common in life. The main material is polyethylene and EVA (ethylene acetic acid copolymer), the same as the usual plastic bags. Different thicknesses are used to distinguish specifications. When the thickness exceeds 0.8mm, it is called "geoboard".

After the dam body is filled and the reservoir bottom is compacted to meet the design requirements, and the composite geomembrane impermeable body protective layer is prepared according to the design requirements, the construction technology of the composite geomembrane impermeable body is: the composite geomembrane is in place and the paving is straight → Butt joint, bottom fiber butt joint (stitching) → membrane material butt joint, hot melt pressure welding → inflation pressure (or negative pressure method) → surface fiber butt joint (sewing) → reserved capacity.

With the development of large ships and the rapid economic development, some low-grade inland waterways can no longer meet the needs of cheap and large ships along the route.
