Matters needing attention in stone step construction

1, squares and roads should not use light plates. Some squares and roads are paved with smooth stones, mainly considering the inconvenience caused by smooth stones to pedestrians in rainy days. When laying a large area, singeing stone should be used, or only local lines and ribbons should be smooth, and most areas should still be singed.

2. The application of granite in environmental art mainly adopts wet installation. Attention should be paid to the improvement of construction technology and technical level of construction personnel, and strict technical disclosure and construction skills training should be carried out for management personnel and construction personnel. In the case of large-scale projects, we can choose the experiments that have been inclined to be carried out in advance, check the effect and coincidence degree, and then carry out large-scale paving.
