Impermeable geotextile is an engineering material used to prevent liquid penetration, which is widely used in various fields such as water conservancy, transportation, and construction. Its main function is to prevent the penetration of moisture, gases and liquids, and to protect the engineering structure from damage.
First, the characteristics of impermeable geotextiles.
Impermeable geotextile has the following characteristics:
1.Strong impermeability: impermeable geotextile is made of polymer materials, which has excellent impermeability and can effectively prevent the penetration of moisture, gas and liquid.
2.Good corrosion resistance: impermeable geotextile has good corrosion resistance, can resist the erosion of various chemicals, and ensure the stability and safety of the engineering structure.
3.Convenient construction: impermeable geotextiles can be laid by different construction methods, such as laying, lapping, stitching, etc., and the construction is convenient and fast.
4.Environmental protection and pollution-free: The impermeable geotextile is made of environmentally friendly materials, which will not cause pollution to the environment and meet the environmental protection requirements of modern engineering construction.
Second, the application field of impermeable geotextiles.
Impermeable geotextiles are widely used in the following fields:
1.Water conservancy engineering: It is used for anti-seepage treatment of water conservancy projects such as reservoirs, dams, and channels to improve the stability and safety of water conservancy projects.
2.Traffic engineering: It is used for waterproof treatment of highways, railways, bridges and other traffic projects to ensure the normal operation and service life of traffic projects.
3.Construction work: It is used for waterproofing treatment of houses, basements, tunnels and other construction projects to improve the durability and safety of buildings.
Third, the production process of impermeable geotextiles.
The production process of impermeable geotextile mainly includes the following steps:
1.Material preparation: Polymer materials are selected as raw materials, such as polyethylene, etc.
2.Ingredients: The raw materials are batched according to a certain proportion to ensure the quality and performance of the product.
3.Production and processing: The raw materials after batching are melted, extruded, stretched and other processing processes to form impermeable geotextiles.
4.Inspection and packaging: inspect the impermeable geotextile produced to ensure that the product quality meets the standard requirements, and package and store.
Fourth, the use of impermeable geotextiles.
The use of impermeable geotextiles is as follows:
1.Pre-construction preparation: clean and level the construction area to ensure that the construction environment meets the requirements. At the same time, prepare the tools and materials required for construction, such as impermeable geotextiles, adhesives, etc.
2.Laying impermeable geotextiles: lay the impermeable geotextiles on the construction area according to the design requirements to ensure that the laying is smooth and wrinkle-free. Adhesive is used at the lap joint to ensure that the lap joint is firm and reliable.
3.Inspection and acceptance: After the laying is completed, the impermeable geotextile is inspected and accepted to ensure that its quality meets the design requirements. If there is any unqualified place, it needs to be treated and repaired in time.
In a word, impermeable geotextiles, as an important engineering material, have been widely used in various fields. It has the characteristics of excellent anti-seepage performance and corrosion resistance, which can improve the stability and safety of engineering structures. In the process of use, it is necessary to pay attention to the construction method and operation details to ensure its normal effect.
