As a new type of support structure, ACC has been gradually applied in many coal mine projects. However, in engineering application, the influence of c-shaped tube insertion depth and structural surface pressure on the reinforcement of ACC is still unclear. In this paper, the laboratory test method was used to establish a tensile and shear test system of the tube cable, and the shear mechanical properties of the ACC under 5 different c-shaped tube insertion depths and 3 different initial preload conditions were tested respectively. The shear load-shear displacement curve of ACC and its shear deformation are obtained. The mechanical properties of the ACC under different c-shaped tube insertion depths on the structural plane were studied, and the effects of the structural plane with and without normal pressure and different preload loads on the shear performance of the ACC were compared and analyzed. The test results show that the insertion depth of the c-shaped tube and the positive pressure of the structural surface have a certain influence on the reinforcement of the ACC under shearing action. The c-shaped tube with a large insertion depth will increase the shear load and shear deformation of the ACC. Compared with the insertion depth of 0mm, when the insertion depth is 50mm, 100mm, 150mm and 300mm, the peak shear load increases by 20.7%, 43.1%, 50.4% and 54.6%, respectively. The greater the insertion depth of the c-shaped tube, the higher the shear resistance of the ACC The better the performance, the reasonable c-shaped tube insertion depth can effectively improve the reinforcement effect of the ACC. Compared with no positive pressure on the structural surface, the positive pressure provided by the initial preload load to the structural surface combined with the high shear performance of ACC can further improve the peak shear load of the entire support system. The peak shear load and shear deformation of ACC under different initial preload loads are significantly different, and the peak shear load and shear deformation of ACC decrease by increasing the initial preload load. The breaking of ACC is mainly due to the combination of tension and shear, and compared with pure anchor cables, ACC has a good ability to enhance the shear strength of rock mass and resist shear deformation. The results of this study can provide reference for the further application design of ACC in coal roadway engineering.
