Application Status of Geogrid in Expressway Construction
Although geogrids have good performance characteristics and are widely used in highway construction, the author finds that only by mastering the correct construction methods can they play their due role. For example, some construction personnel have incorrect understanding of the performance of l...Read more -
Plastic grille has strong “anti rolling” ability
Biaxial tensile plastic geogrid is suitable for various embankment and subgrade reinforcement, slope protection, tunnel wall reinforcement, and permanent bearing foundation reinforcement for large airports, parking lots, docks, freight yards, etc. Increase the bearing capacity of the road (ground...Read more -
The difference between geomembrane and geotextile
Both belong to geotechnical materials, and their differences are as follows: (1) Different raw materials, geomembrane is made from brand new polyethylene resin particles; Geotextiles are made from polyester or polypropylene fibers. (2) The production process is also different, and the geom...Read more -
Application of Filament Geotextiles in Railway Engineering
the most widely known is the use of filament geotextile on highways. In fact, it is also widely used in railway engineering. In addition, filament geotextile materials have always been well known in railway engineering applications. The specification of geotextile shall ...Read more -
Types and uses of geotextiles
In a broad sense, geotextiles include woven fabrics and nonwoven geotextiles. The main raw materials for woven fabrics are PE and PP, with stable performance and long service life, and better performance. Non woven fabrics mainly include short filament non woven fabrics and long filament non wove...Read more -
Application of Geogrid in Dikes
Since the early 1980s, China has started the application and research of synthetic materials such as geotextiles. Through its application in many projects, the advantages of this material and technology are increasingly recognized by the engineering community. Geosynthetics have functions such a...Read more -
What is a geomembrane?
Geomembrane is a geomembrane material composed of plastic film as the impervious substrate and nonwoven fabric. The impervious performance of the new material geomembrane mainly depends on the impervious performance of the plastic film. The plastic films used for seepage prevention at home and ab...Read more -
Detailed explanation, performance, application and construction of dimensional composite drainage network
Using high-density polyethylene as raw material, the ribs are extruded through a special machine head, and the three ribs are arranged at a certain distance and angle to form a three-dimensional space structure with drainage channels. The middle rib has greater rigidity and forms a rectangular dr...Read more -
The Role of Geogrid in Subgrade, Road and Bridge Slopes
Geogrid is a commonly used composite material for road slope ecological slope protection and highway subgrade reinforcement, which greatly enhances the stability and strength of road subgrade and pavement And improve the safety of road driving. For highway slope protection and reinforcement works...Read more -
How to construct geogrids on high-grade highways and airport pavements?
Currently, there are two types of commonly used geogrids: with and without self-adhesive adhesive. Those with self-adhesive adhesive can be directly laid on the leveled base layer, while those without self-adhesive adhesive are usually fixed with nails. Construction site: It is required to compac...Read more -
How to distinguish between non-woven, woven and staple fiber needle-punched geotextiles
Short-filament geotextiles have excellent filtration, barrier, reinforcement and protection effects, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. Geotextiles are divided into woven geotextiles and non-woven...Read more -
