Geotextile is a very common and versatile product and is a geosynthetic material made of fibers through needle punching or weaving into a cloth shape. It is a kind of non-woven and woven fabric products, a new type of geotechnical material used in civil engineering.
Bentonite geosynthetic clay liners have better water resistance than ordinary waterproof blanket. Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Just use bentonite granular or powder and water between the overlap part to connect and fix. No special inspection is required after construction, and it is easy to repair if waterproof defects are found. It provide great convenience for construction workers.
How do wrinkles occur when installing geomembrane? It is related to the many decisions made during design, product selection and installation, as well as the site boundary conditions. So, how can we improve overall global practice?
When describing the reasons for the benefits of growing plants, it is mainly geotextile made of Geotextile Filter Fabric. This fabric can be used for air pruning, drainage and ventilation of the soil where the plants are located.
Since the 1980s, geosynthetics (mostly geotextiles and geogrids) have been used to minimize reflective cracks in asphalt overlays and improve the performance of basic aggregate layers.
The geosynthetics reinforced cushion is composed of a combination of soil cushion and geosynthetics such as a geogrid mat, geocell, etc., which are layered in the cushion. Compared with common cushions, the tensile and shear properties of reinforced cushions are significantly improved, which effectively prevents the cushions from breaking and shearing damage, and ensures the integrity of the cushions. Meanwhile, the rigidity of the reinforced cushion layer is large, which performs the limitation and homogenization of the soft soil deformation and reduces the amount of settlement.
Wuhan Huoshenshan Hospital project utilized a 20cm sand cushion layer + filament nonwoven geotextile + HDPE geomembrane + filament nonwoven geotextile + sand cushion layer to form an impervious structure. "Two geotextiles one geomembrane" refers to two layers of non-woven fabric and a geomembrane in the middle, which was equivalent to putting on a "protective raincoat" for the underground and surrounding environment of the hospital.
Geotextile, also known as geofabric, is usually a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving processing way. In this article, geotextile definetion, types, characteristics, applications have all been described. Specific geotextile can be designed for different construction engineering project requirement.
As a new type of leak control material, HDPE geomembrane liners has been increasingly utilized to a large number of projects thanks to its excellent impervious feature, chemical resistance feature, non-toxic feature, cost-saving feature and other features. Ordinary utilization projects are included landfills, sewage treatment plants, canals lining, reservoirs, chemical plants subgrade lining, fuel refineries foundation and oil tanks lining, etc.
In this article, it will explain waterproofing structure of geomembrane liners/geomembrane composite and their general installation method. The thickness of both single layer geomembrane liners and geomembrane compsoite is a key and principle issue when designing a waterproofing structure. Its best joint method is to use thermal plastic welding machine.
Biaxial Geogrids, geocomposites are both of the ever-expanding line of geosynthetics. These paving synthetics have different applications and provide different functions in paving applications.
Woven slit films (tapes) are flat and have less filtration properties. They are best used in silt retention, separation and stabilization applications for their lower elongation and higher strength. Non Woven Geotextile Fabrics are primarily used in paving, filtration, drainage, separation and pond cushioning.
If you have customers interested in having a pond installed in their landscape, take a look at a few recommendations from Yingfan on building a pond related with choosing a location, filtration system and cusion for hdpe geomembrane liners.
With the rapid development of economic modernization, people's living standards are constantly improving. In order to satisfy people's appetite taste, people are increasingly demanding various kinds of seafood and fish.With the continuous advancement of science and technology, the fish pond hdpe anti-seepage geomembrane enters the farmer's field of vision and is quickly applied due to the advantages of simple construction, short installation period and low cost.
As the key medium of the anti-seepage structure, the geomembrane layer of geotextile composite geomembrane should meet the stress requirements during installation, because the anti-seepage effect of the geomembrane is related to the strength and thickness of the geomembrane.
