First, the type of geomembrane
Geomembrane can be divided into many types according to the material, such as HDPE (high density polyethylene) geomembrane, LDPE (low
density polyethylene),geomembrane, LLDPE (linear low density polyethylene) geomembrane, composite geomembrane and so on. Different kinds of
geomembranes have different performance characteristics and are suitable for different engineering environments.
HDPE geomembrane: has a high service life and good anti-seepage effect, but also has good puncture resistance, tensile resistance, acid and alkali
resistance and corrosion resistance, suitable for pollution, corrosion, acid and alkaline geotechnical construction, such as urban solid waste landfill,
tailings treatment site, waste slag storage yard.
LDPE geomembrane: has a high elongation at break, good flexibility, suitable for road, railway subgrade, subway, basement and other geotechnical construction.
Composite geomembrane: composed of geotextile and geomembrane, it has the advantages of convenient construction, good anti-seepage effect, good puncture
resistance, etc., and is suitable for large-scale field construction anti-seepage geotechnical construction, such as artificial lake anti-seepage, reservoir anti-seepage,
water channel anti-seepage, river anti-seepage and other projects.
Advantage:
Strong impermeability:
HDPE geomembrane has a very high impermeability coefficient, which can effectively prevent the penetration of water and other liquid substances and prevent
pollution.
Light weight, high strength:
the material is light weight, easy to transport and construction, and has a high tensile strength and elongation at break, to meet the needs of high standards of
engineering projects.
Good chemical stability:
it can resist the corrosion of strong acid, alkali and oil, and is a good anti-corrosion material.
Strong weather resistance:
It has good weather resistance and anti-aging performance, and can be used for a long time while maintaining the same performance.
Good environmental performance:
harmless to the environment, will not produce harmful substances, will not pollute the water quality.
Strong adaptability:
can be used in a variety of different harsh geological and climatic conditions, adapt to geological uneven settlement.
Effect:
Environmental protection project:
used for anti-seepage treatment of landfill, sewage treatment plant and other places to prevent leakage and pollution.
Water conservancy project:
as the anti-seepage material of reservoirs, DAMS, channels, etc., to improve the anti-seepage performance and service life of water conservancy projects.
Municipal engineering:
Used for anti-seepage treatment of subway, building underground engineering, sewage pipes, etc.
Garden engineering:
In artificial lakes, rivers, reservoirs and other places as impermeable materials, to protect water quality and ecological environment.
Aquaculture:
As a impermeable material for aquaculture ponds, it provides a leak-free breeding environment and is conducive to the development of aquaculture industry.
Other fields:
It is also suitable for petrochemical, mining, transportation facilities, agriculture and other fields to meet the seepage prevention needs in different scenarios.
Geomembrane construction precautions:
Construction preparation: Before construction, the base surface should be levelled to ensure that no sharp objects protruded, so as not to puncture the soil diaphragm.
At the same time, the required leveling materials such as sand or clay, as well as welding equipment, should be prepared.
Laying and welding: When laying HDPE geomemofilm, it should be naturally developed to avoid excessive stretching or discounting. The two adjacent geomembranes
should be connected by thermal welding or special tape to ensure the sealing of the joints. When welding, the temperature and time should be controlled to avoid
overheating or undercooling leading to poor welding quality.
Inspection and acceptance: After the completion of construction, the HDPE geomembrane should be comprehensively inspected to ensure that it has no defects
such as damage, no bubbles, and no wrinkles. At the same time, acceptance tests, such as leakage tests, should also be carried out to ensure that its anti-seepage
performance meets the requirements.
