Self-repairing high-strength composite geotextile based on MICP technology and preparation method
The invention discloses self-repairing high-strength composite geotechnical cloth based on an MICP technology and a preparation method. The self-repairing high-strength composite geotechnical cloth is composed of first bio-fiber geotechnical cloth, high-strength composite geotechnical cloth and second bio-fiber geotechnical cloth which are sequentially arranged from bottom to top. The first bio-fiber geotextile consists of animal fur fibers, plant stem and leaf fibers and synthetic fibers, and is processed and formed by a needling process; the high-strength composite geotechnical cloth is composed of high-strength warp yarn fibers, high-strength weft yarn fibers and polypropylene fibers, and the high-strength warp yarn fibers, the high-strength weft yarn fibers and the polypropylene fibers are interwoven to form a groined structure in a warp-weft crossing and up-down overlapping Central pores of each #-shaped structure formed by the high-strength warp fibers, the high-strength weft fibers and the polypropylene fibers of the high-strength composite geotechnical cloth are uniform and consistent in size; the second bio-fiber geotextile is formed by needling animal fur fibers, plant stem and leaf fibers and synthetic fibers, penetrating through a central pore of the #-shaped structure of the high-strength composite geotextile and connecting with the fibers of the first bio-fiber geotextile.
本发明公开了一种基于MICP技术的自修复高强复合土工布及制备方法，由自下而上依次布置的第一生物纤维土工布、高强复合土工布和第二生物纤维土工布组成；第一生物纤维土工布由动物毛皮纤维、植物茎叶纤维和合成纤维组成，经针刺工艺加工成型；高强复合土工布由高强经纱纤维、高强纬纱纤维和丙纶纤维组成，以经纬穿越、上下交叠的方式，相互交织形成井字形结构；高强复合土工布的高强经纱纤维、高强纬纱纤维和丙纶纤维形成的各个井字形结构的中心孔隙均匀且尺寸大小一致；第二生物纤维土工布由动物毛皮纤维、植物茎叶纤维和合成纤维经针刺，穿过高强复合土工布的井字形结构的中心孔隙，与第一生物纤维土工布的纤维连接成型。
