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.

The polyethylene geomembrane manufacturer uses a brand-new PE material to make a 6-meter plastic film for use in anti-seepage projects. The thickness of the film is 0.75mm to 2.0mm. Geomembrane is a kind of high molecular polymer material.

The composite geomembrane is strong in adapting to the new environment and has excellent chemical and physical properties.

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.

The characteristics of composite geomembrane materials should consider the design requirements, usually the thickness is not less than 0.2 mm, the total weight per square meter and various characteristics should be selected according to the design requirements, and the width should be selected according to the width of the channel laying.

In order to achieve the dual purpose of obtaining materials on site and dredging the river, graded natural gravel is used as the filling material. However, under the high water level of the river, the embankment filled with gradual natural gravel will seep obviously, causing the embankment or quicksand pipeline to collapse. occur. In order to solve the above problems, composite geomembrane is placed on the front and bottom of the dam.
