The invention discloses a self-water-absorbing composite geogrid, and belongs to the technical field of earthwork engineering. The self-water-absorbing composite geogrid comprises a plurality of transverse ribs arranged at equal intervals and a plurality of longitudinal ribs arranged at equal intervals, wherein the transverse ribs and the longitudinal ribs are perpendicularly intersected and wovento form the self-water-absorbing composite geogrid; and a water-absorbing material is embedded into the transverse ribs and the longitudinal ribs. The self-water-absorbing composite geogrid has the following beneficial effects that 1), water absorbing is achieved, the rib material contains the water absorbing material, water accumulated at a low water level in a reinforcement layer can be suckedout, the influence of accumulated water on the stability of the soil body is reduced, and the drainage consolidation time of the lower soil body is shortened; 2), water permeability is achieved, by adding the water-absorbing material to the ribs, the geogrid is made to form a drainage net, and it is not necessary to combine earthwork cloth for drainage of a treatment layer; and 3), water drainageis achieved, the problem that the polymer water-absorbing material has a water loss characteristic after air-drying is eliminated, the self-water-absorbing geogrid can be partially reversely arrangedon the surface of a dam in a wrapping manner when in use and used for air-drying and draining; and pre-compression-free drainage of the water at the bottom of the dam is achieved through the self-water-absorbing geogrid.
本发明公开了一种自吸水复合土工格栅，属于土工工程技术领域，包括若干等间距设置的横向肋条和若干等间距设置的纵向肋条，横向肋条和纵向肋条垂直相交，编制而成自吸水复合土工格栅；横向肋条和纵向肋条内嵌吸水材料。本发明具备以下优点：1)吸水性：肋条材料含有吸水材料，可以对加筋层内的低水位的积水吸出，减少因积水对土体稳定影响及下部土体的排水固结时间；2)通水性：通过在肋条中添加吸水材料，使土工格栅形成排水网，无需联合土工布进行处理层的排水；3)排水性：根绝高分子吸水材料具有晾晒后失水特性，自吸水土工格栅可在使用时，部分反包于堤坝表层，用于晾晒排水；实现堤坝底部的水通过自吸水格栅的无预压外排。
