Geotextiles for construction-manufacture,factory,supplier from China

Geosynthetics are geosynthetic materials that are widely used in geotechnical engineering today, and they are a generic term for polymer products. As early as the 1920s, the chemical industry successfully produced synthetic materials, but it was not until the late 1950s that these materials were gradually promoted as a new type of construction material for geotechnical engineering. The early products were mainly permeable woven and non-woven geotextiles, and later impermeable geomembranes were produced.

The characteristics of filament geotextiles are as follows:High strength and high draft: The strength and draft capacity of filament geotextiles are higher than those of ordinary geotechnical materials, and can withstand high loads and stresses in different engineering environments.Acid and alkali resistance, aging resistance: Filament geotextiles have good acid and alkali resistance, are not affected by the environment, and have high durability.Good penetration and good drainage performance: the mesh of filament geotextile can selectively hinder the movement of soil particles, but it does not

1、InsulationThat is, the application of filament geotextile to have different chemical properties (particle size, dispersion, mortar consistency and relative density, etc.) of the construction of raw materials (such as sand and sand grains, sand and gravel, sand and soil mix, etc.) to carry out isolation.

During the "Tenth Five-Year Plan" and the "Eleventh Five-Year Plan", China plans to make huge investments in various projects such as water conservancy, electric power, transportation, environmental protection, river management, etc., including water conservancy construction, the South-North Water Transfer Project, electric power investment, highway and railroad construction, environmental engineering construction, as well as ports, airports, garbage disposal, river and lake management, sand control, etc. The investments amount to trillions of yuan.

Quality filament geotextiles grasp the following three points:1, look at the defects. Knitted polyester fabric appearance defects more, serious defects will affect the effect of wearing. Such as leaky needle hole, lack of silk, hook silk, broken head, silk pulling tight and serious weft slanting, etc.. Lighter defects, such as color difference, rolled edge, bad edge, spell silk, knotted knot, color flower, reflection, oil-colored silk, thick and thin silk, etc. Although the cloth with light defects can be worn, but affect the grade of the fabric.2、Look at the appearance.

What is the main function of geogrids1. If used in road construction, geogrids can not only help increase the bearing capacity of the foundation, effectively extend its service life, but also effectively prevent cracking or collapse of the ground, thereby ensuring that the ground can maintain a beautiful and flat appearance.2. If used in culvert construction, geogrids can effectively prevent cracks and collapse of culverts.

                                                                              The importance of auxiliary geotechnical materialsIn civil and construction engineering, the use of auxiliary geotechnical materials can enhance and stabilize the structure of infrastructure such as soil, stone, or water.

                                                                           Do you know the function of HDPE geomembraneOf course, HDPE geomembrane is a geosynthetic material made of high-density polyethylene material, mainly used for anti-seepage isolation, anti-seepage leakage, popularization of highway construction, water conservancy engineering, and environmental protection in civil engineering.

 Filament polyester nonwoven geotextile plays a role in railroad engineering  Filament polyester non-woven geotextile is a kind of geosynthetic material made of polyester filament fibers with high strength, corrosion resistance, aging resistance and good water permeability.  Filament polyester nonwoven geotextiles are needed for railroad construction mainly because they have a series of excellent properties, which can help enhance the stability and bearing capacity of the soil, and improve the durability and safety of the railroad roadbed.

                                                                Performance characteristics of geotechnical cells1. It has flexible expansion and contraction, can be transported and stacked, and can be tensioned into a mesh during construction. It is filled with loose materials such as soil, gravel, and concrete, forming a structure with strong lateral limitations and high stiffness.2.
