The following are the construction considerations for composite high quality gravel geocell (1) Use must be embedded: the thickness of the cover should not be less than 30cm. (2) The renovated anti-seepage system should be composed of cushion layer, anti-seepage layer, transition layer and protective layer. (3) The soil should be firm to avoid uneven settlement and cracks, and the turf and tree roots within the impermeable area of ​​the wholesale plastic geocells should be removed. Lay small-diameter sand or clay as the protective layer on the contact surface with the membrane. (4) When laying, the geomembrane should not be pulled too tightly. It is better to bury the soil at both ends into a corrugated shape. Especially when anchoring with rigid materials, a certain amount of expansion and contraction should be left. (5) During construction, stones should be avoided, and heavy objects should be directly hit on the plastic geocells factory price. It is best to construct, lay the membrane, and cover the protective layer during construction.

What is the permeability coefficient of HDPE impermeable plastic geocells manufacturers? Due to its chemical structure, polyethylene is a (substantially) impermeable substance. Polyethylene is composed of very long molecules, and indeed there is molecular space (sometimes called "free space") between individual polyethylene chains. When we say that polyethylene is essentially non-permeable, the existence of these spaces is also recognized. Osmosis can also occur, for example, when the pressure of the permeate is very high or the molecules of the permeate are very small. However, the degree of penetration shown by polyethylene is difficult to determine using existing test methods. Therefore, the test results often reflect the imprecision of the test process rather than the permeability of the material. An independent laboratory conducted tests on HDPE impermeable membranes and obtained the following results: It must be emphasized that due to differences in molecular shape, polarity and state (gaseous or liquid), different chemicals will have different permeability. For example, relatively small water molecules (atomic weight 18) will penetrate polyethylene more easily than larger molecules such as cyclohexanol (atomic weight 94). The polarity of the molecules must also be considered (similar to the proverb "similarities blend together"). HDPE impermeable biaxial geogrid for sale polyethylene is a non-polar molecule, so other non-polar molecules can be larger than polar molecules such as water. For reference, polyethylene is usually used as a packaging for raw materials including gasoline, motor oil, household cleaners (ie bleach), muramic acid, pesticides, insecticides, fungicides and other highly concentrated Chemicals. Some chemicals may be absorbed by other materials, but this will only happen at very high concentrations. These chemicals include halogenated hydrocarbons or aromatic (aromatic) hydrocarbons in concentrations exceeding 50%. Their absorption causes swelling and slight changes in physical properties, such as increased elongation. This includes many types of fuels and oils. However, this does not affect the ability of HDPE impermeable 3D geonet for sale liners to act as impermeable barriers for these materials. As a result, the permeability of HDPE impermeable membranes is usually extremely low, which is almost negligible.

What should be paid attention to before cutting HDPE impermeable wholesale plastic geocells? Before cutting HDPE geomembrane, the relevant scale should be accurately measured, and then cut according to practice. Generally, it is not suitable to cut according to the scale shown in the figure. It should be numbered piece by piece and recorded in a special form. On the top, when laying geomembrane, we should strive to have fewer welds. On the premise of ensuring quality, try to save the original data. At the same time, it also simply guarantees the quality. The lap width of the joint between the membrane and the membrane is generally not less than 10cm, usually the welding seam is placed parallel to the large slope, that is, along the slope direction, usually in the corner and deformation section, the joint length should be as much as possible Shorten. Except for special requirements, within 1.5 meters from the top slope or stress concentration area on slopes with a slope greater than 1: 6, no welding seam should be provided as much as possible to prevent artificial wrinkles. When the temperature is low, it should be tightened as much as possible. Flatten HDPE impermeable fiberglass geogrid manufacturers. All-digital AC servo motor and driver are selected, directly connected to the motor, small size, high efficiency, and extremely low noise. It has high driving rigidity, large acceleration and deceleration acceleration, and improved reliability. Realize constant velocity displacement control, constant velocity experimental force control, constant velocity strain control, control function, all digital hardware implementation, HDPE impermeable high quality 3D geonet has strong anti-interference ability, good stability, high degree of software integration, contains a variety of The data experiment specification template is selected to be related to the flatness of the underlying layer, the allowable tensile stress of the data, the elastic modulus of the data, the head and the particle size of the cover layer in the laying range, and the HDPE geomembrane thickness planning takes into account the strength required mainly by the water pressure In addition, it is necessary to consider the use conditions such as exposure, burial pressure, climate, service life, etc., using synthetic fiber or glass fiber as a reinforcement material, and a new type of geotechnical material that is compounded with a composite geomembrane.

Precautions for the construction of geomembrane welding machine: The quality of the plastic geocells manufacturers seam affects the following projects. Generally, the seam can be glued or geomembrane welding machine. The two membranes of the geomembrane should be reserved for 10--20 cm sides, select the geomembrane welding machine corresponding to the weld, adjust the gap between the geomembrane at the joint, ensure the width of the joint, flat, without wrinkles, and dust Wait. Geomembrane welding machine hot welding is the heating of the surface of the PE high quality plastic geocells, which is heated by the pressure roller to melt them. Adjust the temperature and rate when welding with the geomembrane welding machine, and use the hot air torch to repair the places that can not be welded by the geomembrane welding machine. Friendly reminder of the manufacturer of plastic geocells for sale welding machine: Geomembrane thickness less than 0.25mm should be bonded with KS glue. If it is too thin, air holes or damage can occur and the anti-seepage effect cannot be achieved. The laid geomembrane should be welded and tested.

1. Protection; Protect the geomembrane to avoid the loss of anti-seepage function caused by the destruction of garbage or gravel. The wholesale biaxial geogrid enables the geomembrane to maintain a longer service life. 2. Isolation effect; Used as a barrier between waste / gravel or soil / gravel to prevent solids from entering the leachate drainage system and leachate conditioning tank. 3. Strengthen the effect; Before laying the geomembrane, the fiberglass geogrid for sale reinforces the slopes with poor original conditions (excessive movement, poor stability, etc.) and soft soil foundation.

Before the laying of the composite film, the earthwork of the channel is filled and the slope surface is finished. The flatness and compaction of the slope surface meet the design requirements and the laying of the composite film can only be carried out after the acceptance of the supervision engineer. 1. Construction preparation 1) Quality inspection of composite membrane materials. The composite high quality fiberglass geogrid used in the project is a two-cloth one-membrane composite geomembrane. Before use, the quality inspection center station is entrusted to inspect various technical indicators of the product. All indicators meet the standards and design requirements. 2) Clearing and leveling the dike slope, removing all sharp-angled debris, backfilling the rammed under-slope, sloping the rich slope and passing the supervision and acceptance, and providing a working surface for the laying of composite geomembrane 3) Splicing in the geomembrane field In order to facilitate the construction and ensure the splicing quality, the composite wholesale fiberglass geogrid should be as wide as possible to reduce the amount of on-site splicing. Before construction, the composite geomembrane width and site length needs to be cut in the unit and spliced. To meet the required size of the block, roll it on the steel pipe, and manually transport it to the working surface to lay it, and it is necessary to avoid damage to the material.

Its tensile strength, elongation at break, strong resistance to puncture 4. Low price and wide application 5. Stable material and strong resistance to chemical agents 6. wholesale fiberglass geogrid manufacturers explain that the seams are connected by double seams with hot welding machine. The seams have high strength and complete testing equipment, which is not easy to produce.

Composite geomembrane is widely used in various anti-seepage projects. The large number of applications of geosynthetics in civil engineering, especially in flood control and emergency rescue projects, and their effectiveness have attracted the great attention of the majority of engineering and technical personnel. The composite geomembrane is widely used in the channel anti-seepage project of irrigation area. Combining the construction practice, let's talk about the construction method of composite HDPE geomembrane factory price. The composite geomembrane is heated by oven far infrared on one or both sides of the film, and the geotextile and geomembrane are pressed together to form a composite geomembrane. Its form has one cloth and one film, two cloths and one film, etc. Geotextile is used as a protective layer of wholesale HDPE geomembrane to protect the impervious layer from damage. In order to reduce ultraviolet radiation and increase anti-aging properties, it is best to use the buy method to lay. In construction, the sand or clay with a smaller material diameter should be used to level the base surface first, and then the geomembrane should be laid. The geomembrane should not be stretched too tightly. The part buried in the soil at both ends is corrugated. Finally, use a layer of fine sand or clay to lay a 10cm filter layer on the geomembrane. Lay a 20-30cm stone as a protective layer against impact. During construction, every effort should be made to prevent stones from directly hitting the HDPE geomembrane for sale, and it is best to carry out the protective layer construction while laying the membrane. The connection between the composite geomembrane and the surrounding structure should be anchored with expansion bolts and steel plate beading, and the connection part should be coated with emulsified asphalt (thickness 2mm) to prevent leakage at this place.
