Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.

Meat duck net raising fast fattening technology
Compared with grazing and ground leveling, meat ducks have the advantages of saving labor, saving labor, saving padding, not subject to seasonal restrictions, and have the advantages of fast growth, low disease incidence, and high feed conversion ratio. Practice has proved that online fattening ducks can greatly shorten the feed cycle and increase economic efficiency. After 45 to 50 days of feeding, the meat duck live weight up to 2.5 kg and the survival rate is above 97%. The duck fattening technology for fast-growing ducks is introduced as follows: I. Feeding equipment settings Ducklings on the Internet require a well-structured duck house. The cement floor must have a certain slope, a drainage ditch, and a sewage pool outside. The net bed adopts angle iron or wooden frame structure, generally 40 to 50 cm from the ground, and the width is 1 to 3 meters. Put angle iron or bamboo on the horizontal shelf, spacing 2 to 3 cm. The upper layer is padded with plastic mesh. A 50 cm-high fence is placed on the outside of the grid, and a sink and a trough are set inside the fence. Second, the feeding and management of meat ducks 1? Feed: Feed full price pellets, require particle material diameter: 1 to 21 days of age is 3 mm; after 21 days of age is 6 to 8 mm; can also be fed with powder wet mix . Feed nutrient levels: 18% crude protein, 6% crude fiber, 0.85-1.2% calcium, 0.48% phosphorus, and 16% crude protein, 6% crude fiber, and 0.8% to 1.2% calcium at 3 weeks of age Phosphorus 0.44%. 2? Feeding and drinking water: Ducklings within 1 week of age often maintain feed in the pan (slot); 5 weeks of feeding at 2 weeks old, 1 feeding at night; 3 feedings of 3 weeks above 3 weeks, 1 feeding at night . Ducklings drink 5% to 8% of sugar water within 24 hours after hatching. They can also feed a quick-filling solution of vitamins and trace elements. Afterwards, they can freely drink water and wash the sink once a day. 3? Shelter temperature: 1 to 3 days old at 35°C; 4 to 7 days old at 32°C; thereafter, it falls at 2 to 3°C per week, and it desorbs after 21 days of age. 4? Humidity: Relative humidity of 70% in the first week, 65% in the second week, 60% later. 5 light: 1 to 3 days of age 24 hours of full light; 4 to 10 days of age, the use of natural light during the day, sooner or later turn on the light to feed; after 10 days of natural light. 6. Feeding density: 15 eggs per square meter from 1 to 7 days; 6 eggs per square meter after 21 days of age. Third, the disease prevention and control measures Ducklings 3 to 7 days of age with 0.01% of drinking water to prevent digestive tract diseases; 15 to 20 days of intramuscular injection of duck attenuated freeze-dried vaccine. Keep the ducks in a dry, sanitary, ventilated environment Good, the feces under the bed is cleaned once every 3 days to prevent rat damage. The outside environment of the duck house is sprayed with 2% to 3% of fiery alkali water every 10 to 15 days; once every 5 to 7 days in the duck house, it is disinfected once with a disinfectant such as perchloric acid and peracetic acid.
