Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying t......

In order to effectively improve the construction quality of composite geomembrane, construction quality management is required, and quality management is generally guaranteed from two aspects. One is to ensure the quality of raw materials, and the other is to ensure the quality of the construction p......

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficu......

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 ......

There are two ways to lay composite geomembrane on the upstream dam surface of the earth dam. The other is laying perpendicular to the dam axis (horizontal laying). There are 7 anti-slip tooth grooves on the upstream slope, and the tooth groove spacing is 5-10m. The bottom of the tooth groove is 1m ......

Before laying the composite geomembrane, it should go through the inspection of the excavation of the exhaust trench, and complete the finishing and leveling of the bottom and slope of the storage.
