The soil nails are used for connecting the concrete panel and the soil body and improving the slope stability, the operation of inserting the soil body is complex, and the materials are used more, so that the proper quantity and the installation sites which can well meet the structural strength of the soil nail wall can be determined before construction, and if the quantity of the soil nails is increased only by adjusting the large surface position of the reinforcing steel bar net, the construction cost performance is lower.
In addition, the control of the spraying thickness of concrete is also a great difficulty in construction, and the quality of the concrete is difficult to control accurately. When the quality test is carried out, the insufficient spraying thickness of the concrete can be compensated by the repair spraying, but the reworking repair spraying not only can slow the progress of the project, but also has great influence on the structural integrity of the concrete panel.
