What are the advantages of using warp-knitted composite geomembrane in dams
For dams, in order to avoid damage caused by water and soil erosion, it is often necessary to use specific materials for protection. Due to the relatively high tensile properties of the warp-knitted composite geomembrane, the effect of using it on dams is worthy of recognition. First of all, the upper part of the seepage problem is the most problem that should be solved in the construction of the embankment. Due to the existence of seepage, the embankment is often damaged. Therefore, the use of warp-knitted composite geomembrane to prevent seepage is the most effective way to avoid landslides. Secondly, long-term scouring of the base of the dam will also cause long-term erosion and collapse of the base of the dam. Using warp-knitted composite soil

Application of geomembrane in modern aquaculture and anti-seepage function
In more and more large-scale and intensive modern fish ponds, shrimp, loach, lotus root ponds, and fish ponds, waterproof and anti-seepage material geomembranes are more and more favored by farmers. This is because the special farming geomembrane has obvious economic and social benefits compared with the traditional farming model. Whether it is used for ornamental fish ponds or fishing grounds, the main function of HDPE geomembrane is to avoid contact between fish and soil and water pollution. Geomembranes can both prevent the accumulation of waste in the soil and prevent harmful chemicals such as ammonia, hydrogen sulfide, acids, iron and other potentially harmful compounds from entering the pond. so that

Under what circumstances is it suitable to use special adhesive for geomembrane?
Recently, as the company's geomembrane sales volume has gradually increased, customer consultation on geomembrane issues has also increased with the sales volume. The most common problem is how to connect geomembrane and geomembrane properly. Today, the editor of Shandong Engineering Technology Co., Ltd. will answer this question in detail. First of all, if you use a large amount of geomembrane, or the membrane is relatively thick, you can use welding to connect the geomembrane. Maybe you don't know it very well, but in fact, during the construction process of geomembrane, certain auxiliary materials are needed, such as glue. Glue plays an important role in the whole construction process, for

In order to achieve a good anti-seepage effect in the artificial lake, three anti-seepage materials are used for anti-seepage comparison. The anti-seepage membrane material has good anti-seepage performance, strong adaptability to deformation, light material, convenient transportation, and strong corrosion resistance. It has the advantages of simple construction, short construction period and low cost. 1. Geomembrane anti-seepage Geomembrane is a kind of anti-seepage material made of high molecular polymer as the basic raw material. The main function is to prevent liquid leakage and gas volatilization. The raw material of geomembrane is a polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, good corrosion resistance, low temperature resistance and frost resistance. Among them, the amount of HDPE anti-seepage film is the highest.

Incorrect cutting of geotextiles will affect its working efficiency
Incorrect cutting of waterproof geotextiles will seriously affect work efficiency and cause waste of waterproof geotextiles. In fact, it is more appropriate for each piece of waterproof geotextile to be 20m wide after sewing. If it is too narrow, the waterproof geotextile will be laid many times, resulting in waste, which does not meet the requirements of cost control. To cut the round head part of the waterproof geotextile, first divide the circumference formula c=2πr by 2 to calculate the semicircle circumference of the round head, which is the length of the outer edge line of the waterproof geotextile, and then according to the cutting width of the waterproof geotextile, use a compass to press With a scale of 1:100, draw the number of geotextiles that need to be cut along the outer edge of the laying, and then according to the number of bottoms. It is not difficult to predict that my country's demand for geotextiles will increase significantly in the future.
