Antiweathering, high strength water conservancy network

[0008] From figure 1 Among them, we can see that the present invention includes mesh bars 1 and mesh knots 2. The net knot is the intersection point of each mesh bar, and the shape of the grid is a regular rhombus, of course, it can also be a rhomboid, a flat rhombus or other polygons. Since the knots in the grid structure are easily damaged, the thickness of the knots is much greater than the thickness of the bars. The invention is made of high-density polyethylene resin, treated with anti-aging technology such as antioxidant and light stabilizer, and the aging test shows that the strength retention rate of the product is greater than 80% after 10 years of use.

[0009] The present invention can use nets to make net cylinders or cages filled with stones to form a whole, which can resist the attack of strong wind and waves. Because the stone cylinders or stone boxes made have good water permeability, weather resistance and are not corroded by seawater, And it can absorb wave im
