Compared with the prior art, the utility model has the advantages and positive effects that:

cement carpets are fusion products of woven materials and cementitious materials. The toughness of the woven material counteracts the weakness that ordinary concrete is too rigid and easy to crack, and the compressive failure resistance and compressive elastic modulus of the cement blanket exceed those of the ordinary concrete in terms of material strength. Meanwhile, the bottom of the cement blanket is provided with a waterproof and seepage-proof material. The waterproof and chemical corrosion resistant performances are better, and the fireproof performance is obviously improved compared with that of common concrete. The cement blanket can be rolled up for bulk transportation, so that the transport cost and the labor cost are saved, and the cement blanket is very convenient for workers to assemble and disassemble and transport. And the shape of the cement blanket can be cut and placed at will. In the past, cement carpets can be used in special shapes or places where common concrete is difficult to mold, and in most cases, large mechanical assistance is not needed. Once laid, hydration reaction occurs after watering, and the cement blanket can reach 80% strength within 24 hours. In addition, the durability and maintenance problems which are most difficult to treat by the traditional concrete are solved, and the cement blanket is surpassed, and because the middle of the cement blanket is a three-dimensional fiber framework, the cement blanket is not easy to break compared with common concrete, and the erosion of wind, rain and chemical substances is difficult to permeate. In the aspect of maintenance, the effect can be achieved by only coating a layer of cement paste, and compared with common concrete, the cement paste has the advantages of time saving and money saving.

Cement carpets have made a breakthrough in terms of scour resistance. The cement-based woven fiber blanket is characterized by having a thickness of 1-5cm and comprising a mesh surface cloth layer, a stainless steel wire layer, 3D alkali-resistant glass fibers, a plastic geotechnical cloth layer and a protective isolation layer which are sequentially arranged from top to bottom.

The water flow protection device has the advantages that the original water flow property can be not disturbed or is less disturbed as much as possible, and the influence on a protection area is less. The cement blanket is arranged in a protective engineering way, so that the outline of the whole protection is kept smooth, no obvious protruding part or concave part exists, and the cross section of the water flow is not compressed or is less compressed as much as possible, so that the general flushing is reduced. In the water flow top flushing or inclined flushing section, the water facing side slope of the protective building should be properly slowed down when the water facing side slope is conditional so as to alleviate local flushing.
