Method for detecting void ratio of stone laying structure in grid

The invention relates to a method for detecting the void ratio of a stone laying structure in a grid, belongs to the technical field of ecological grid and gabion box construction, and realizes the detection of the apparent density of stone laying in the grid and the detection of the stacking density of the stone laying structure by combining an existing standard test detection method. According to the detection method, the structural form of the grid rubble is not considered, and the accumulation volume of the grid rubble can be detected only by dividing and measuring the residual net cage after the rubble is moved out, so that the void ratio of the rubble in the grid is calculated. 一种网格内砌石结构检测空隙率的方法，属于生态网格、石笼网施工技术领域，通过结合现有规范的试验检测方法，实现了对网格内部砌石表观密度进行检测，并对砌石结构进行堆积密度检测。这种检测方法，不用考虑网格砌石结构形式，只需要对搬出砌石后剩余网箱分割进行测量，就能检测出其堆积体积，从而计算出网格内砌石空隙率。
