Geogrid for cold region and use method of geogrid
The invention provides a geogrid for a cold region and a use method of the geogrid, and belongs to the field of geogrids. The ribs are crossed in pairs and are arranged in the window; the main body is made of an elastic material and can elastically deform; the two ribs divide the window into two first cavities and two second cavities, the shape memory deformation piece is V-shaped and penetrates into the edges, surrounding the first cavities, of the two ribs, and the two ends of the shape memory deformation piece extend in the direction away from the intersection position of the two ribs. The shape memory deformation piece is cooled to shrink and deform, and the distance between the two ends of the shape memory deformation piece is reduced in the preset direction; the shape memory deformation body shrinks and deforms in a low-temperature environment to drive the width of the cavity to shrink, so that a trend force shrinking in the preset direction is formed on the geogrid, the width of the window is reduced, and the amount of the soil body protruding out of the window and separating from the rock-soil body is reduced; and weakening of the reinforcing effect of the geogrid on the rock-soil body is avoided.
本发明提出了一种用于寒冷地区的土工格栅及其使用方法，属于土工格栅领域，主体上沿布设有若干窗口；若干肋条两两相交叉并设置在窗口内；主体采用弹性材料制成并能够弹性形变；两个肋条将窗口分隔为两个第一腔体及两个第二腔体，形状记忆形变件为V形并穿置在两个肋条围绕第一腔体的边缘内，形状记忆形变件的两端朝远离两个肋条交叉部位的方向延伸，形状记忆形变件受冷收缩形变并使其两端沿预设方向的间距缩小；形状记忆形变体在低温环境下收缩形变，带动腔体的宽度也收缩，从而在土工格栅上形成沿预设方向收缩的趋势力，使窗口的宽度缩小，减少土体从窗口中凸出并脱离岩土体的量，从而当回到日间较高温度时，避免削弱土工格栅对岩土体的加固效果。
