It is mainly divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane. MechanismThe main mechanism is to cut off the leakage channel of earth dam with the impermeability of plastic film, to bear the water pressure and adapt to the deformation of dam body with its large tensile strength and elongation rate; and non-woven fabric is also a kind of short polymer fiber chemical material, which has high tensile strength and elongation through needling or hot sticking forming. After it is combined with plastic film, it not only increases the tensile strength of plastic film Because of the rough surface of the nonwoven fabric, the friction coefficient of the contact surface is increased, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, they have good corrosion resistance to bacteria and chemistry, and they are not afraid of acid, alkali and salt erosion. They have long service life under the condition of dark useThe performance characteristics of HDPE geomembrane are as follows: 1. HDPE geomembrane is a kind of flexible waterproof material with high anti-seepage coefficient (1 × 10-17cm / s); 2. HDPE geomembrane has good heat resistance and cold resistance, and its use environment temperature is high temperature 110 ºC, low temperature - 70 ºC; 3. HDPE geomembrane has good chemical stability, and it can resist the corrosion of strong acid, alkali and oil; 4. HDPE geomembrane has high tensile strength, which can meet the needs of high standard engineering projects; 5. HDPE geomembrane has strong weatherability and strong anti-aging properties. It can be exposed for a long time to maintain its original performance. 6. The overall performance of HDPE geomembrane, HDPE geomembrane has a strong tensile strength and elongation at break, so that HDPE geomembrane can be used under various adverse geological and climatic conditions. The strain force is strong to adapt to the uneven settlement of geology; 7. HDPE geomembrane is made of high-quality raw plastics and carbon black particles without any preservatives. HDPE has been used to replace PVC as the raw material of food packaging bags and fresh-keeping films in China Main application 1. HDPE geomembrane is suitable for environmental protection and sanitation, such as landfill, sewage treatment plant, power plant regulating pool, industrial and hospital solid waste, etc; 2. LDPE anti-seepage membrane is applicable to water conservancy projects, such as anti-seepage, leakage stoppage, reinforcement, anti-seepage of water channel, vertical core wall, slope protection, etc; 3. HDPE anti-seepage membrane in Municipal Engineering: subway, building underground engineering, planting roof, roof garden, sewage pipe anti-seepage; 4. Polyethylene impervious membrane is suitable for Garden: artificial lake, river, reservoir, water pond bottom of golf course, slope protection, waterproof and moisture-proof of green lawn, etc; 5. High density polyethylene geomembrane is suitable for petrochemical industry: chemical plant, oil refinery, oil storage tank anti-seepage, chemical reaction tank, sedimentation tank lining, secondary lining, etc; 6. Polyethylene geomembrane is suitable for mining industry: washing pond, heap leaching pond, ash yard, dissolving pond, settling pond, storage yard, bottom liner of tailings, etc; 7. Low density polyethylene film is suitable for traffic facilities: foundation reinforcement of highway, seepage prevention of culvert; 8. LDPE anti-seepage membrane is suitable for agriculture: anti-seepage of reservoir, drinking water pool, impoundment pond and irrigation system; 9. HDPE film is suitable for aquaculture industry: intensive, industrialized aquaculture pond, fish pond, shrimp pond lining, sea cucumber ring slope protection, etc; 10. High density polyethylene anti-seepage membrane is suitable for salt industry: salt field crystal pool, brine pool cover, salt film, salt pool plastic coverConstruction method The geomembrane shall not be dragged or hard dragged during transportation to avoid sharp object stabbing. 1. It should be extended from the bottom to the high position, not too tight, and 1.50% of the remaining width should be reserved for local sinking and stretching. Considering the actual situation of the project, the slope shall be laid from top to bottom; 2. The longitudinal joints of two adjacent frames shall not be on a horizontal line, and shall be staggered for more than 1 m; 3. The longitudinal joint shall be more than 1.50M away from the dam foot and bending foot, and shall be set on the plane; 4. First slope, then field bottom; 5. When the slope is laid, the spreading direction shall be basically parallel to the maximum gradient line. Lay 1. Before laying the geomembrane, the corresponding qualification acceptance certificate of civil engineering shall be provided. 2. Before cutting the geomembrane, the relevant dimensions shall be measured accurately, and then cut according to the actual conditions. Generally, it is not suitable to cut according to the dimensions shown in the drawing, and it shall be numbered one by one and recorded on the special form in detail. 3. When laying the geomembrane, try to minimize the welds and save the raw materials as much as possible on the premise of ensuring the quality. At the same time, it is easy to guarantee the quality. 4. The lap width of the joint between the membrane and the membrane is generally no less than 10cm, which generally makes the arrangement direction of the weld parallel to the maximum slope, that is, along the slope direction. 5. Generally, in the corner and abnormal section, the joint length shall be minimized. Except for special requirements, no weld shall be set as far as possible within 1.5m from the top slope or stress concentration area on the slope with a gradient greater than 1:6. 6. During the laying of geomembrane, artificial fold shall be avoided. When the temperature is low, the geomembrane shall be tensioned and paved as much as possible. 7. After the geomembrane is laid, walking on the membrane surface, moving tools, etc. shall be minimized. All objects that can cause harm to the impermeable membrane shall not be placed on the membrane or carried on the membrane to walk, so as to avoid accidental damage to the membrane
