A: Comparison of economic benefits (case 2/3/4 data):
project | Hot melt anchor scheme | Concrete internal support scheme |
Cost | Reduced by 30%~50% | benchmark |
Construction period | Shorten by 3~6 months | benchmark |
Recycled material value | 100% steel strands are reused | No recycling value |
Benchmark case:
· Shenzhen Meiyuan Project (Case 3): adjacent to the subway, displacement ≤ 23.5mm, saving 20 million yuan;
· Suzhou Ancient Building Group Project (Case 4): 3.2m away from the control and protection building, with a displacement of ≤8mm, to achieve zero interference construction.
