Problems solved by technology

However, because this kind of geotextile is easily punctured by the filler, which affects the isolation and reinforcement effect; the degree of occlusion with the soil is low, and the tensile properties are poor; it is easy to age and has poor corrosion resistance.

Embodiment Construction

[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...

Abstract

A high-weatherability and -strength water conservancy net for protecting slope of dike and treating foundation is composed of net ribs and nodes which is the cross point of net ribs. The net check has diamond shape. Its advantages are high stability, strength and impact resistance.

Description

Technical field [0001] The invention relates to a water conservancy net used for preventing river bank scour, coast slope protection, foundation treatment and other projects. Background technique [0002] At present, most of the geotextiles used (formerly called geotextiles, non-woven fabrics) are made of polypropylene resin, and stones are used as fillers to prevent river bank erosion, coast slope protection and foundation treatment. However, this kind of geotextile is easily punctured by fillers, which affects the isolation and reinforcement effect; the degree of occlusion with the soil is low, and the tensile properties are poor; it is easy to age and has poor corrosion resistance. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of geotextiles, the present invention provides a water conservancy net with high strength, anti-aging and corrosion resistance. [0004] The beneficial effects of the present invention are that, due to t...
