FAQ of geosynthetics :

 

What is geosynthetics ?

 

Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary.

 

What kinds of geosynthetics we have ?

 

Non-woven geotextile, geogrids, geocells, GCL, Geomembranes, Geonets, Geocomposites etc .

 

What is the geosynthetics used for ?

 

Hydraulic

 Lagooning and Water Treatment, Ornamental Ponds, Golf Courses

 Aquaculture and Desalination,Water Lagoons,Tanks, Reservoirs, Liquid Waste,Floating Cover Solutions, Drainage and Filtration

Q:Method for laying geogrid
Geogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosynthetics. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and fiberglass polyester geogrid.
Q:Who knows the evaluation criteria and technical disclosure of Geogrid
1) place: in the surface layer of 50cm thick sand gravel or sand (egg) gravel cushion, and compaction, which is not only conducive to improve the friction between the soil and the grid, but also conducive to the consolidation of the foundation drainage
Q:Highway construction steps?
The specifications are as follows: Geogrid TGDG25 TGDG35 TGDG50 TGDG80 TGDG110 TGDG120 TGDG150 width of 1 meters -3 meters; bidirectional geogrid TGSG20-20 width 2.5-5m TGSG15-15 TGSG25-25 TGSG30-30 TGSG40-40 GS30-30 GS50-50 m; plastic composite grid GS60-60 GS80-80 GS80-60 GS150-150 width 4-6m meters; BJG35-35 BJG50-50 BJG60-60 BJG80-80 glassgrid width 4-6 meters;
Q:How many grams per square meter of 15KN Geotextiles
The square Mick weight of polyester staple fiber geotextiles 15KN is 500 grams
Q:How to distinguish from the appearance of plastic geogrid and fiberglass geogrid
Appearance difference is obvious,
Q:How much is the tensile strength of geogrid?
Solder paste type: 200KN or less
Q:What is the distance between the waterproof plate and the top of the tunnel?
Some of the design drawings, the specification seems to be unable to find, which is related to the location of longitudinal flexible drainage pipe
Q:What is the purpose of this approach for the treatment of geogrid slopes in embankment slopes?
Do you understand the true role of geogrid?
Q:What is the cost per cubic meter of reinforced earth retaining wall
2, the use of Geogrid on the railway to avoid the soft ground on the basis of the railway premature settlement and destruction of real estate3, the geogrid used in the dam, dam, river, canal, Wai sea embankment, reservoir reinforcement and other water conservancy projects4, geogrid reinforced airport foundation can greatly improve the bearing capacity of the runway, to ensure the safety of aircraft landing
Q:Self adhesive fiberglass geogrid price 1m2 how much money
This also depends on the specific specifications of the model
