Geogrid factory is designed and synthesized to study the physical structure characteristics of materials: 1. The thickness of geosynthetic material is expressed in mm. The polymer mesh with square or rectangular shape formed by biaxial geogrid manufacturer can be divided into unidirectional tension and biaxial tension according to the different tensile directions during manufacturing. It is to punch holes on the extruded polymer sheet (the raw materials are mostly polypropylene or high-density polyethylene), and then conduct directional stretching under heating conditions. Using polypropylene plastics (PP) and special additives, the mine plastic mesh manufacturers have successfully developed flame-retardant and antistatic plastic belts for underground coal mines by using plastic directional stretching, flame retardant and antistatic technologies. Through the inspection of national quality inspection department, the mining plastic mesh fully meets the requirements and obtains the production license. Glass fiber geogrid manufacturer is a new excellent geo technical base material for strengthening road surface and subgrade. The product is made of alkali free glass fiber filament as the main raw material, woven by unique warp knitting weaving technology and coated with special rubber. The change of the thickness of the fabric has a great impact on the hydraulic properties of the fabric, such as porosity, permeability and filtration. The common thickness of various geosynthetic materials is: geomembrane 0.25-0.75mm, thickness up to 2-4mm; composite building materials, we can sometimes use thin geomembrane, thin up to 0.1mm; the thickness of geogrid varies with different parts of the country, and the rib thickness generally ranges from 0.5mm to tens of mm. 2. Unit management area teaching quality construction unit use area development quality is the quality of geosynthetic nano materials per unit working area. It reflects the safety performance of enterprise materials through various aspects, such as tensile strength, bursting strength and other mechanical system performance analysis, as well as for the porosity, permeability and other hydraulic properties, usually expressed in g / m2, which is geotechnical engineering

Physical properties of synthetic geogrids factory

The physical properties of geogrid factory are as follows

Thickness 1. The thickness of geosynthetics is expressed in mm. The change of thickness has great influence on the hydraulic properties such as porosity, permeability and filtration. The thickness of various commonly used geosynthetics is: geomembrane 0.25 ~ 0.75 mm, thick composite materials up to 2 ~ 4 mm; sometimes thin geomembrane is used, the thickness of thin geogrid will change, and the rib thickness is generally between 0.5 ~ dozens of mm.

The mass per unit area is the mass per unit area of geosynthetics. It reflects many properties of materials, such as tensile strength, fracture strength, porosity, permeability and other hydraulic properties, usually expressed in g / m2. It is one of the important physical properties of geosynthetics. The unit area mass of geotextile and geomembrane is affected by the density, thickness, admixture and water content of raw materials. The mass per unit area of common geotextiles is generally between 50 ー 1200g / m2.

Construction technology of geogrid factory:

Detection and cleaning of lower bearing layer → manual laying of Engineering geogrid → lapping, binding and fixing → paving subgrade soil of upper structure → rolling → testing

According to the width required by the design of geogrid factory on the flat bearing layer, the upper and lower parts of the geogrid are sealed with fragments of unarmed bad geogrid. The high-strength direction of geogrid is perpendicular to the axial direction of the embankment. The geogrid is horizontally placed with laying tension, which can avoid wrinkle, twist or pothole. The geogrid is spliced longitudinally by this method, and it is not less than 20cm Connection width. After the geogrid is laid, the artificial filler and the upper layer after rolling shall be laid in time to avoid long-term exposure, and for those using mechanical transmission materials, leveling, rolling and mechanical spread spectrum shall be rolled from both sides to the middle, and the rolling from both sides of the middle with its compactness shall be regulated. When all construction vehicles and construction machinery are prohibited from driving or parking on the laid geogrid, we often check the quality of the construction geogrid. We find that the damage, puncture, tear and other damage, according to the degree of repair or replacement.
