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 growth of the service life of expressways, problems such as network cracks, grooves, and cracks have appeared. It not only affects the stability and comfort of the car, but also causes surface water to penetrate into the road base and weaken the bearing capacity of the road base.

Impermeable film commodities have been used in many engineering industries. Aquaculture is the most popular.

The anti-seepage geomembrane is polyvinyl chloride and polyethylene, a polymer chemically flexible material, which has the characteristics of small proportion, high elongation, strong deformation habit, corrosion resistance, low temperature resistance and good cold resistance.

Geomembrane is a flexible geosynthetic impermeable material, and the stability of its underlying support layer is one of the keys to the safety of geomembrane. If the underlying support layer has obvious uneven deformation and local erosion, the geomembrane will be partially torn, forming a leakage channel, threatening the safety of the project.

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.
