Termite control of cables

Termite-prevention buried cables for buried plastic cables have many advantages over overhead overhead cables: savings in materials, stable communications, confidentiality and safety, no fear of typhoon blow-off, less arable land, and no obstacles to traffic, are currently being widely used. Since the 1940s, cable plastics have developed rapidly. In most cases, polyvinyl chloride (PVC) and polyethylene (PE) are used as cable jackets. It has good electrical properties, low cost, and easy production and use. Corrosion resistance and other advantages, has been widely used in communications and power transmission. However, these cables also have the problem of being generally harmed by termites. Here are some ways to prevent termites from feeding. Ecological prevention of ants 1, possible avoidance method: In the survey line, as far as possible to avoid the ants suffering from serious areas, such as forests, cemeteries and so on. 2. Sand-buried cable method: Fill 30 cm of river sand at the bottom of the cable trench, lay cables on the sand, and then cover 30 cm of sand on the cable and the side walls before compaction. It is difficult for termites to damage the cable through the sand layer. 3. Water level buried method: The cable buried below the water level, such as under the rice field or the cable trench to dig deep to 1.5-2 meters, can also avoid the harm of milk termites. 4. Ant cable protection: Place the cable in the cement or hard plastic jacket layer, and then use the anti-item material to bond at the joint of the casing. Drug treatment The most widely used drug treatment is the poisonous soil method and the injection of the drug into the cable sheath to achieve the purpose of preventing termite damage. 1, drug treatment of soil or processing jacket 2, made of drug-containing cable sheathing dam termite prevention and control methods to make new and old dams, consolidate the achievements of prevention and control, take preventive measures, must adhere to the "prevention, prevention and control The principle of comprehensive management and the gradual elimination of this is the fundamental measure for realizing the long-term stability of dams and dams. Eradication of termite breeding grounds and protection of the environment Through continuous perseverance in the termite breeding area of ​​500-1000 meters in the vicinity of dams, it is possible to effectively control the spread of termites to dams around dams and to consolidate the results of dam prevention and control.

one. Elimination of termites, winged adults, light trapping, artificial killing, and biological control. Surface treatment of dykes 1. Change the ecological environment of termites in levees 2. Chemical treatment of soil 3. Laying of anti-virus soil 3. Treatment of Embankment Foundations New embankments should be carefully inspected for the presence of termites prior to construction. Strict removal of termite hazards on the dam base and nearby hills. Use chemicals to treat the soil and poison termites.
