High-strength degradable geotechnical sand bag and preparation method thereof
The invention discloses a high-strength degradable geotechnical sand bag which comprises geotechnical sand bag cloth, biological curing powder and filling sand. The geotechnical sand bag cloth comprises an inner wear-resistant layer, a natural degradable framework layer and an outer wear-resistant layer which are arranged in sequence. The inner wear-resistant layer is manufactured by drawing various degradable chemical fiber materials into fibers, carding the fibers into a net shape and adopting a needling process; the natural degradable framework layer takes high-strength plant fibers as raw materials and is tightly needled on the inner wear-resistant layer; the external wear-resistant layer is positioned on the other side of the natural degradable framework layer; the inner wear-resistant layer, the natural degradable framework layer and the outer wear-resistant layer are combined to form the soil engineering sand bag cloth through a hot melting and crimping process; the biological curing powder is arranged between the natural degradable skeleton layer and the external wear-resistant layer; the degradable soil engineering sand bag is formed by folding soil engineering sand bag cloth and sewing the soil engineering sand bag cloth, and the degradable soil engineering sand bag is filled with filling sand.
本发明公开了一种高强可降解土工砂袋，包括土工砂袋袋布、生物固化粉剂、以及充填砂；土工砂袋袋布包括依次布置的内部耐磨层、天然可降解骨架层、以及外部耐磨层；内部耐磨层是将多种可降解化纤材料拉丝成纤维后，梳理成网状后，采用针刺工艺制作而成；天然可降解骨架层以高强度植物纤维为原料，紧密针刺于内部耐磨层上；外部耐磨层处在天然可降解骨架层的另一侧；内部耐磨层、天然可降解骨架层、以及外部耐磨层通过热熔压接工艺，组合形成土工砂袋袋布；生物固化粉剂置于天然可降解骨架层和外部耐磨层之间；可降解土工砂袋是由土工砂袋袋布对折后缝制而成，且可降解土工砂袋内填充有充填砂。
