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:What is the reason for the change of geocell to geogrid
Hello, you must also know that geocell and geogrid are not the same products,
Q:I would like to ask the geotechnical engineering of highway engineering, geogrid raw materials for the conventional test items, parameters?
The conventional detection of geogrid includes: appearance, physical properties (including: Determination of mass per unit area, amplitude measurement, mesh size measurement)
Q:What are the procedures for using two-way geogrid
1 bidirectional geogrid is used to increase the bearing capacity of the road (ground) foundation, and the service life of the Yan Changlu (ground) foundation.2 bidirectional geogrid used to prevent road (ground) surface collapse or crack, keep the ground beautiful and tidy.3 bidirectional geogrid for the construction of convenient, time-saving, labor-saving, shorten the construction period, reduce maintenance costs.
Q:There are several types of basalt fiber geogrid
It is estimated that which is the boring manufacturers to use basalt fiber grille
Q:What is the geogrid GSJ80/HP
4, mixed with asphalt compatible materials - glass fiber geogrid treatment process after coating is designed for asphalt mixture, every fiber is fully coated with high compatibility with asphalt, so as to ensure that the glass fiber geogrid in the asphalt layer and not in isolation of asphalt mixture but, firmly together.5, physical and chemical stability, through special postprocessing agent coating, glass fiber geogrid can resist all kinds of physical and chemical erosion wear, can resist biological erosion and climate change, ensure that its performance is not affected.6, lock and limit the aggregate because of glass fiber geogrid is mesh structure, aggregate in asphalt concrete can be run through them, thus forming a mechanical interlock. This restriction hinders the movement of aggregates, so that the asphalt mixture in the case of load can achieve better compaction state, higher load capacity, better load transfer performance and smaller deformation.
Q:History of geotechnical materials
Geosynthetics are widely used in geotechnical engineering at present, which is a general name of polymer products. As early as in 1920s, the chemical industry was successful in the production of synthetic materials, but it was not until the late 50s that the material was gradually used as a new type of building materials to be used in geotechnical engineering. In the early stage, the products were mainly pervious to spinning and non-woven geotextiles, and later produced impermeable geomembrane. With the requirement of engineering practice and the improvement of manufacturing technology, the geogrid and other composite products with high strength reinforcement are manufactured. In this way, the original geotechnical fabric word has not summarized all kinds of products in the international meaning, so there are many alternative names, the geotextile material was the most common, but the habit still referred to as geotextile. Geotechnical material is divided into several categories of materials: geotextile, geomembrane, geogrid, drainage board, composite geomembrane, geotextile, geocell, bentonite waterproof blanket, etc..
Q:How much is the tensile strength of geogrid?
Whole plastic stretch type: two-way products: 15KN--50KN one-way products: 50KN---300KN
Q:Basic introduction of fiberglass geogrid
With resistance and aging properties of alkali resistant properties, widely used in asphalt pavement, cement concrete pavement and roadbed reinforcement; both rigid pavement and flexible pavement can be applied, compared with the traditional pavement, can reduce the cost, prolong life, prevent road reflective crack. Fiberglass geogrid can also be used in railway, airport, water conservancy, dams and other soft soil reinforcement and road base reinforcement.
Q:What is the difference between Geogrid and geogrid
Glass fiber mesh used in exterior wall, interior wall paint, mainly to prevent cracking, different materials at the junction of mortar plastering material hollowing. Local node reinforcement will also be used. Geotextile has excellent filtration, drainage, isolation, reinforcement, seepage prevention, protection, light weight, high tensile strength, good permeability, high temperature resistance, anti freezing, anti-aging, corrosion resistance. Common non-wovenUsed in the water layer, polyethylene polypropylene fiber waterproof is also used.
Q:Geosynthetic materials for flood control materials
Such SPE.Shows that a large number of engineering practice, geomembrane impervious good, general permeability coefficient K =10cm/s ~ 10cm/s; has great flexibility and adaptability to deformation ability; have good aging ability, under water, water is more durable. According to the anti aging test, it can be concluded that the service life of the polymer geomembrane buried in soil and water can be up to 50 years, and the service life of the high-density geomembrane in the dam is more than 100 years. Mainly made of geogrid, geogrid, belt, soil gabion, geotextile tube, geotextile bag, Geomat, EPS, geocell and so on, it is used for soil reinforcement and reinforcement. Such as the reinforcement of soft soil foundation, steep slope, retaining structure built in the stable foundation, embankment collapse rescue.
