What Methods should be Paid Attention to During the Construction of Geomembrane


Construction method:

 

Do not drag or pull the geomembrane during transportation to avoid injury from sharp objects.

1. Extend from the bottom to the high position, don't pull it too tightly, and leave a margin of 1.50% to prepare for local sinking and stretching. Taking into account the actual situation of this project, the slope shall be laid from top to bottom;

2. The longitudinal joints of two adjacent panels should not be on the same horizontal line, and should be staggered by more than 1m;

3. Longitudinal joints should be more than 1.50m away from the dam foot and bend foot, and should be located on a plane;

4. Slope first and bottom of the field;

5. When laying on a slope, the film spreading direction should be basically parallel to the line of maximum slope.

Layout:

1. Before laying the geomembrane, the corresponding qualified acceptance certificate of the civil engineering should be obtained.

2. Before cutting the geomembrane, the relevant dimensions should be accurately measured and then cut according to the actual size. Generally, it is not advisable to cut according to the size shown in the figure. It should be numbered piece by piece and recorded in detail on the special form.

3. When laying geomembrane, we should try to minimize the number of welds, and save raw materials as much as possible under the premise of ensuring quality. At the same time

Easy to ensure quality.

4. The lap width of the seam between the film and the film is generally not less than 10cm, usually the welding seam arrangement direction is parallel to the maximum slope, that is, arranged along the slope direction.

5. Usually in corners and deformed areas, the length of the joints should be as short as possible. Except for special requirements, on slopes with a slope greater than 1:6, within 1.5 meters from the top slope or stress concentration area, there should be no welds as far as possible.

6. When laying the geomembrane, avoid artificial wrinkles. When the temperature is low, it should be tightened and flattened as much as possible.

7. After the geomembrane is laid, it is necessary to minimize walking and moving tools on the surface of the membrane. Anything that can cause harm to the impermeable membrane should not be placed on the membrane or carried on the membrane to avoid damage to the membrane. Cause accidental damage.

Geomembrane Liners for Hydroelectric Power Plants

  In a world where "going green" is the cool thing to do, harnessing water power in the form of hydroelectricity is the largest source of clean, renewable energy available today. Hydroelectric power is reported to account for 52% of renewable energy generation in the U.S. and 7% of total electricity generation, and failure to achieve reliable and consistent water flow could leave millions of people stranded. The various types of hydroelectric plants in use today each have their own unique geomembrane uses to assist in the protection and delivery of water within their systems, helping to more efficiently provide green energy to the public.   Impoundment The most common form of hydropower generation is the impoundment behind a dam. The reservoir created by the dam is the key to this system. This harnessed water flows through a turbine and connects to a generator, which in turn generates electricity and connects to the consumer. Containing as much water as possible and directing...

What is the Basic Principle of a Geocell?

The reason why the geocell has excellent functions and has attracted the attention of the engineering community, we should also start with its basic principles. When describing its principle in foreign literature, it is called "a honeycomb three-dimensional confinement system, which can significantly improve the performance of ordinary filling materials in load-bearing and pest control applications in a large range." Its key principle is three-dimensional confinement. As a   Geocell Manufacturer , share with you. Geocell For Slope Protection Everyone knows that when a car is driving on the desert, it will press two deep tracks, the pressed part sinks deeply, and the two sides of the track will bulge high. If the vehicle behind continues to advance along the rut, the sinking part will sink further, and the bulging part will bulge further, until the bulging part hits the chassis of the car, and the sinking rut buries most of the wheels, making it impossible to move forward. The...

Geo Liners for Decorative Ponds

Geo liners for decorative ponds help to enhance the beauty and value of your property. Whether the pond will be for aesthetics, attracting wildlife, fishing, or lacing up your skates in the winter; there are many factors to consider when designing and building your dream pond.   Area and Depth Depending on the climate and intended use of your constructed pond, depth may be more of a factor than most people realize. If the pond will be constructed in a climate with four seasons and is intended to maintain fish stock; certain areas, depths, and slopes are suggested to allow aquatic life to thrive. For a vibrant fish population or cool swimming hole, a minimum pond area of 1/2 to 1 acre is recommended, with as much as the pond as possible reaching a depth of 15 feet and side slopes at 1:3 for fish habitat and 1:4 for swimming access. This combination of depth and relatively steep side slopes help reduce aquatic plant growth. An irregular shoreline is also helpful for fishery habitat....
