Field Test Study on Cutting Obstacle Piles Directly by Shield Cutters

Abstract:

Shield cutting obstacle pile directly has significant economic and social benefits compared to traditional methods, however, the corresponding cutting technology is far from mature currently in the international. Based on the construction need of cutting 14 bridge piles with the diameter of 1.0~1.2 meters by Suzhou subway shield, the preliminary scheme of cutter configuration was studied and proposed first, and then the worlds first field test of shield cutting reinforced concrete piles was carried out, the effect and rule of shield cutters cutting piles were analyzed, and the cutter configuration scheme was verified and optimized. The test results indicate that the shell cutter is fit for cutting reinforced concrete pile, its cutting effect on rebar and concrete is shear cutting; In order to make rebar shorter, we should make the rebar be cut off instead of pulled off as possible as we can. The main damage form of shell cutter is alloy cracked. Cutting side pile produces more damage on shell cutter than cutting central pile. The shell cutter configuration scheme should not only satisfy the whole cutting ability and covering the entire cutting plane, but also to be favorable to fix rebar by surrounding concrete.
