Geotechnical construction has become a more important work in our daily life. The use of geotechnical data in the process of geotechnical construction is particularly important, especially the use of geotextile manufacturers china, which has been recognized and concerned by a wide range of customers and friends, including a wide variety of geotextiles. However, any damage in the use of geotextile products still needs to be repaired.The quality requirements of geotextile manufacturers china must not be relax.

The normal construction process of geotextile operation is to spray asphalt glue oil evenly on the cracked road surface first, then lay the fabric interlayer, and then heat the pavement layer on it. The hot pavement layer should be able to absorb the glue oil under the fabric to make it reach the fullness, so it needs the fabric to have excellent adsorption ability. In its operation, there will often be damaged geotextile, at this time, do not waste it, They can stop mending, the mended geotextiles can be reused, and at some level, they also reduce our consumption cost

The application of geotextile manufacturers china is very common, I believe you have a certain understanding. Today, the main thing brought to you is the application of Geotextile in highway maintenance. The main purpose of Geotextile in highway maintenance is to protect the moisture of new pavement and extend the service life of road. The detailed main table is as follows:

(1) Geotextile can be applied to strengthen asphalt pavement, cement concrete pavement and subgrade. It can be applied to both rigid pavement and flexible pavement. Compared with the traditional pavement, it can reduce the cost, extend the service life and avoid the reflection crack of the road

(2) Geotextile products are suitable in thickness, easy to be separated from asphalt pavement, and form an isolation layer after being separated from adhesive layer oil, which has the function of waterproof and heat preservation

(3) The quality of geotextile is light and high strength, which is very suitable for the technical requirements of Geotextile in the process of highway construction

(4) The surface of geotextile is rough and not easy to slide. When laying, the rough surface shall be upward after special treatment to increase the friction coefficient and the separation force of the surface layer, so as to avoid being rolled up and damaged by the wheels during construction, and at the same time to prevent the vehicles and Pavers from slipping on the cloth

(5) The geotextile for highway maintenance is easy to construct and has good application effect, while the fiber of common geotextile is easy to be taken up by vehicle tires, which causes hanging of the fiber, and even can be rolled up in serious cases, forming displacement and structural damage of geotextile

Geotextile is made of non-woven fabric. It is mainly used to strengthen the foundation. Geomembrane is made of high-density polyethylene, and it is mainly used to prevent seepage. The connection between the two is composite geomembrane, which is divided into one cloth, one membrane and two cloth, one membrane, with stronger anti-seepage function

Geotextile manufacturers china, is a kind of permeable geotextile material made by needling or weaving the constituent fibers. The products are cloth like, usually 4-6 meters wide and 50-100 meters long. Geotextile is divided into woven geotextile and non-woven geotextile

Geotextile manufacturers china has excellent filtration, drainage, barrier, reinforcement, anti-seepage and protection effects. It has light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. The geomembrane at the construction site is made of plastic film as the anti-seepage base material and non-woven fabric, Its impervious function mainly depends on the impervious function of plastic film

At present, PVC, PE and EVA are the main plastic films used for anti-seepage at home and abroad. They are a kind of polymer chemical flexible materials with small proportion, strong extensibility, high habit of deformation, corrosion resistance, low temperature resistance and good frost resistance

The primary mechanism is that the impermeability of plastic film is used to separate the leakage channel of earth dam, and the water pressure and deformation of dam body are accepted with its larger tensile strength and elongation rate; the non-woven fabric is also a kind of short polymer fiber chemical data, which has high tensile strength and elongation after acupuncture or hot sticking forming, and it is connected with plastic film, It not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the touch surface due to the rough surface of the non-woven fabric, which is conducive to the stability of the composite geomembrane and the protective layer. Together, they have good corrosion resistance to bacteria and chemicals, and are not afraid of the corrosion of acids, alkalis and salts

The use scale of geotextile and geomembrane is not the same. Geotextile manufacturers china has the effect of strengthening, barrier layering, filtering, drainage and safety in engineering. Geomembrane is mainly used in projects with high impervious requirements, such as seepage prevention, barrier, reinforcement, crack prevention, reinforcement, horizontal drainage, etc. in engineering construction. Both of them can have their own effects and can be combined to show their respective interests
