Description

Technical Field

[0001] The utility model relates to the technical field of cement blankets, in particular to a cement blanket for irrigation channels. Background Art

[0002] The scientific name of cement blanket is concrete canvas. It is a soft cloth impregnated with cement. When it comes into contact with water, it will undergo a hydration reaction and harden into a very thin, waterproof and fireproof durable concrete layer. It is mainly used in ditch irrigation. Although the irrigation channel cement blanket currently used can meet the use requirements of irrigation channels, it still has defects in actual use;

[0003] For example, the patent publication number CN219133489U provides an irrigation channel cement blanket, which is provided with a non-woven fabric layer, a woven fabric layer, a textile fabric layer and a bottom film layer, and a cement-based composite material layer is filled between the woven fabric layer and the textile fabric layer, wherein a covering layer is provided on the edges around the cement-based composite material layer; it can prevent the cement-based composite material from falling off;

[0004] However, the cement blanket has poor wear resistance. Since there are a large number of protrusions inside the irrigation channel, the cement blanket is easily rubbed against the protrusions when it is laid, causing the bottom film on the surface of the cement blanket to rupture, affecting the protective performance of the cement blanket. At the same time, during the construction process, workers walking on the cement blanket are also likely to damage the top leak-proof layer, thereby affecting the waterproof performance of the cement blanket. Therefore, a cement blanket for irrigation channels is proposed. Utility Model Content
