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 ?

The description of HDPE Geomembrane for Environmental Projects water conservancy projects landfill mining  canal
Geomembranes are impermeable geosynthetics that, until recently, were mainly used as canal and pond liners. However, modern technology has broadened liner applications to include landfills, wastewater treatment lagoons, oil and gas exploration (including hydraulic fracturing or "fracking"), aquaculture, irrigation ponds and remediation. In many of these applications, a nonwoven geotextile is used as a cushion to protect the geomembrane. In general, geomembrane liners offer excellent puncture resistance and can withstand a wide range of chemicals and temperatures. They are also highly flexible and conform well to the subgrade.

Q:How to ensure the quality of geogrid laying?
, the geogrid is not the number of laying, the quality is not serious non-compliance of the event, causing the attention of the relevant departments, in the report is to assess the quality of railway construction in central and southern Shanxi:
Q:Which is better than geotextile and geogrid
Drainage protection isolation can also be used for road subgrade reinforcement geogrid is mainly used in highway railway roadbed reinforcement and retaining wall reinforcement
Q:What are the criteria for the use of plastic geogrid
Each grid has a variety of specifications, the specific reference to the national standard requirements, but the specifications are not necessarily the same as the national standard.
Q:How much is a square grille
Warp knitted polyester geogrid, unidirectional tensile plastic geogrid and soil in underground coal mine with two-way stretch plastic biaxially oriented plastic guard net, steel plastic composite geogrid, coal mine with two-way welding plastic top net, high strength spiral rib steel wire grid model, integrated 3D Geomat, high strength geogrid, geocell, engineering fiber, geotextile composite geomembrane, whichincludesimportedwetthinfeltproductionline engineering materials etc..
Q:What is geogrid, what is the role?
Glass fiber grille is made of high quality enhanced E-glass fiber yarn, woven into the substrate with the foreign advanced warp knitting, warp knitting with directional structure, make full use of the fabric yarn strength, improve its mechanical properties, so it has good tensile strength, tensile strength and creep resistance, planar network shaped material and high quality modified asphalt coating processing and into. The follow similar compatibility principle, highlighted with the composite performance of asphalt mixture, and fully protect the glass substrate, which greatly improves the wear resistance and anti shearing ability of the substrate, which can be used to enhance the resistance, cracks, rutting of highway asphalt pavement, the end of the problem is difficult to increase.
Q:Bi directional plastic geogrid is suitable for engineering
Applicable to all kinds of embankment and roadbed reinforcement
Q:What are the physical properties of Geosynthetics
2, the quality of unit area: the quality of the unit area of the unit area of geosynthetics. It reflects the properties of materials in many aspects, such as tensile strength, bursting strength and mechanical properties such as porosity, permeability and hydraulic performance, usually expressed as g / m2, is one of the important physical properties of geosynthetics. The quality of geotextile and geomembrane per unit area is affected by the density of raw materials, and the influence of thickness, admixture and water content. The commonly used geotextile fabric area quality is generally in the range of 50 ~ 1200g / m2
Q:Fiberglass grille and geogrid which use more
Geogrid is made of polypropylene, PVC polymer and thermoplastic or molded by two-dimensional grid or a certain height of the three-dimensional mesh screen, when used as civil engineering, called geogrid.
Q:Physical characteristics of geogrid construction method
1, with a strong tensile strength, tensile strength in the range of 25-110kn/m, according to the product model is not the same, tensile strength is not the same.2, the stress elongation is small, the structure has a good lateral stability and enhance the ability.3, high physical and chemical stability, anti-aging, anti soil burial, good corrosion resistance.4, the friction coefficient is large, the net structure is fully integrated into the earth and rock structure to enhance the stability of the structure.5, the resistance to environmental stress is strong, when the stress is enhanced with a small amount of deformation, in the -20 to 120 degrees centigrade range of temperature deformation coefficient is small.6, the width of the general 4 -6 meters, light installation construction is simple and convenient, efficient, economic.
Q:Geosynthetic materials for flood control materials
Geosynthetics can be divided into geotextile, geomembrane and geotextile composite materials, special geotechnical materials 4 categories: fabric is a kind of porous material, with polypropylene, polyester and nylon and other synthetic fiber materials, according to the production method can be divided into shape, fabric two other non woven. The fabric style is to use a series of single chain according to a certain way woven, generally by the orthogonal warp and weft two group fiber woven fabric; non plastic geotextile is made of short fiber and long fiber directional or random order, by acupuncture or thermal bonding, chemical bonding, the biggest characteristic the strength is no obvious direction, so its use is wide.The aging rate of geotextiles is closely related to the intensity, temperature, humidity, the type and color of the raw materials, the structure of the fabric and the environmental conditions.
