Release time: 2017-04-13 22:57 1379 views

Domestic geotextile manufacturers with a certain production scale and technical level feel that geotextiles are not only of great significance to improve the quality of current rivers, lakes, and seas remediation projects in China, and reduce project costs, but also to open up markets and adjust the structure of the textile industry. It is also of great significance. Under the background of the state's active adjustment of fiscal policies and expansion of investment in basic construction, it can become a shining "bright spot" in China's current economic development. Geotextile mainly refers to a new type of synthetic material used in civil engineering, using high-molecular polymers such as polypropylene and polyester chips as raw materials. According to production methods, it can be divided into non-woven, woven, synthetic and other types. Different types of geotextiles have different functions. It mainly has filtering function, drainage function, isolation function, reinforcement function, anti-seepage function, and protection function.

First, the geotextile market is huge. According to statistics, 75% of the existing 250,000 kilometers of dykes in China require foundation treatment and reinforcement. Historically, water conservancy projects have been the application market of geotextiles. Only the first phase of the Yangtze River Estuary Deepwater Channel Regulation Project requires 14 million square meters of composite geotextiles, 670,000 square meters of non-woven geotextiles, and geotechnical models. The bag is 590,000 square meters, and the amount is very considerable. In addition, a large number of geotextiles can also be used in highway, airport construction, railway, and environmental protection projects. The development of geotextiles will also help textile companies to turn losses into profits and promote structural adjustment of the textile industry.
Geotextile is widely used in water conservancy, highway, seawall, railway, airport and other projects, which plays an important role in improving the quality of the project, reducing the cost of the project, and accelerating the progress of the project. It is hailed as the fourth place after steel, wood and cement. Kind of building material. In foreign countries, the United States began to use geotextiles in the late 1950s, and the world-famous Dutch coastal defense project built in the late 1950s also used geotextiles in large quantities. A large number of geotextiles are used in various projects in Germany, France, the United Kingdom, and Japan. At present, more than 100,000 projects in more than 100 countries and regions around the world use more than 1 billion square meters of geotextiles (about 400,000 tons) each year, and they are increasing at an annual rate of 9%.
